Ah, I wasn't aware IsNullOrWhiteSpace wasn't available until .NET 4.0, good point then.

lewax00 18-Oct-13 17:29pm View

I agree, that is a much cleaner option.

I wanted to +5 this too, but then realized you were the answerer. You might want to edit that information into your answer though, it's kind of important.

lewax00 25-Jul-13 10:07am View

In what context? A C++ server with JavaScript client side in a web browser? A C++ program that can be scripted with JavaScript? This makes no sense as it's written.

lewax00 23-Jul-13 12:03pm View

Does that even compile? I'm pretty sure when passing arrays as parameters you have to specify the size in the parameter list or use a pointer. [e.g. void callbyvalue1(char a[10],char b[10]) or void callbyvalue1(char *a, char *b)]

Sorry, but you're just going to have to make that effort if you want real help.

Then it sounds like it's an internal problem, you need to find out who's changing it and why. Or decide if everyone really needs access to sa.

Make sure no one else has the password to sa (and make sure it's sufficiently secure as to not be guessed easily), and make sure no other account has authority to change it.

I mean I don't have Chrome installed. I know it has a debug console by default, I just can't confirm the shortcut.

lewax00 12-Jul-13 14:09pm View

But did you fix that on your page? Could be related.

As for debugging JS:
Firefox: Ctrl+Shift+K
IE: F12
Chrome: (from comment below, I don't have it installed) Ctrl+Shift+I

Any of those should give you the errors from JS.

Are your jQuery and jQuery UI scripts actually in different folders? Because they're pointing to different paths.

If you have a question, please post your own question instead of bumping up a 2 year old question (I'm assuming that's what you were going for, because I see no relation to the question in your "solution").

lewax00 11-Jul-13 12:32pm View

I think that covers most of the options, +5.

I'm a little hazy on the details, but could you also use a union for this?

lewax00 10-Jul-13 16:33pm View

Like I said, if it is an option, it would be in your BIOS. I don't know what's in your BIOS, each one is different. For example: my home PC's has many options relating to over clocking, my work PC does not. But my work PC allows me to have my computer automatically boot everyday at the same time, an option my home PC doesn't have. Of course, such logging could still be disabled the same way a locked BIOS could be.

If you really can't remove the CD drive, then your best option is really to lock the BIOS, then physically lock the case. (The thing I'm talking about is visible in this image: http://archive.benchmarkreviews.com/images/reviews/cases/Ultra_m998/ULT40069_ExtLock.jpg it's the thing with the hole that's sticking through the slot in the case.)

lewax00 10-Jul-13 14:47pm View

Encrypting the hard drive is no good if the user in question has the key of course. It's awfully difficult to secure a computer from it's primary user (if that is the asker's goal).

lewax00 10-Jul-13 14:44pm View

That's become a surprisingly viable option recently. My home PC has no CD drive, and I rarely miss it. The one in my work PC has never been used by me either.

And yes, the USB is still an issue, if the mobo supports that option (not all of them do, I had a new laptop about 4 years ago that didn't, but it was a rarity even then).

lewax00 10-Jul-13 14:40pm View

That's a more interesting question...I'm not aware of a BIOS with that capability, but it's not infeasible (which is where the logging would have to be triggered I would think). You'd have to look around in your machine's BIOS to determine if it had such a feature.

Would another option be physically locking the cases? Most cases have a small metal loop that prevent the case from opening when something is put through it (usually a lock or metal cable). Then the BIOS password might still be viable, because they wouldn't be able to get inside the case.

lewax00 10-Jul-13 14:07pm View

Trying to program your own BIOS or editing the existing one is a bad idea. If you make one mistake, your motherboard could be completely bricked. And for something this complex and delicate, if you have to ask how, then you aren't ready to do it. You're better off taking Richard's advice and just changing the settings, which should allow you to do what you want. As far as resetting the BIOS by removing the battery, if someone has physical access to your machine there's nothing you can do to stop them. They could just pull out your hard drive and put it in another computer and do whatever they want to it, same with any other piece of hardware.

If you want a better answer, why do you want to create this restriction? Maybe there's another way to accomplish your goal.

lewax00 8-Jul-13 15:58pm View

lewax00 5-Jul-13 18:18pm View

Try opening it via a command line window and see if there are any errors. (Go to the directory it's in, hold shift + right click, and select "Open command window here", then type in the file name and press enter. If the option doesn't show up, make sure you're not highlighting any files.)

lewax00 5-Jul-13 18:14pm View

+5, but for mobile applications, don't forget Java as well, considering Android is a major player in that space.

lewax00 27-Jun-13 19:00pm View

Any reason you aren't using the % operator instead of a function? Should be faster than function call.

lewax00 27-Jun-13 18:57pm View

Exactly. +5

lewax00 27-Jun-13 9:58am View

Are you sure your data isn't entirely non-ASCII characters (this is a more accurate term for what you want, technically all of them are Unicode)? Also, what format of Unicode is it? UTF-8, UTF-16...?

lewax00 26-Jun-13 23:47pm View

I highly doubt Java was used in writing any Windows OS. Especially considering there is no JVM installed initially.

lewax00 26-Jun-13 20:09pm View

Assuming of course it is well formed XML, but not all HTML is. I think a plain TextReader/TextWriter would be more appropriate, if you don't plan on using related XML structures.

lewax00 25-Jun-13 11:15am View

What kind of files? The method would be completely different for every kind of file, and with some it will not be possible.

lewax00 24-Jun-13 10:07am View

Hmm...I guess the first thing to check here is: does CurrentThread.CurrentCulture return the same value in both cases? Could be coincidence that it worked in the first place.

lewax00 20-Jun-13 13:00pm View

Not entirely relevant, but why are you making a browser that would most likely be run inside another browser? Seems like a strange design decision to me.

lewax00 20-Jun-13 12:58pm View

Best practice seems to be putting scripts at the end now, so the page can finish loading before the scripts are run.

lewax00 18-Jun-13 18:19pm View

Care to add a source for that? It could be useful information to have as part of the answer.

lewax00 14-Jun-13 20:13pm View

Well without having access to the code, and with no error logs, its impossible to know. So here's another shot in the dark that was the cause of similar errors I've encountered: you're trying to access some file, registry key, etc that requires administrator permission, and you've only tested on computers with UAC disabled, so it worked in your test environment, but not on the client machine that has UAC enabled. Get them to try running it as admin, if it works, then I'm likely right.

lewax00 14-Jun-13 19:18pm View

By "here in the U.S." do you really mean "on my machine"? Or have you actually tested it on other computers?

lewax00 11-Jun-13 17:35pm View

Technically speaking, there are no ASCII characters above 127. ASCII is a 7-bit encoding, only capable of representing 0-127, anything higher requires an eighth bit, which makes it extended ASCII, and is not standard across platforms.

lewax00 6-Jun-13 12:38pm View

Then it's a problem with the API. I can write to HKCU without elevation on Windows 7 just fine; this is how it's supposed to work. If the API requires elevation for HCKU that's a problem with the API, not UAC.

lewax00 6-Jun-13 12:37pm View

Deleted

You didn't specify which section it's in there, it's probably going to HKLM, which like I said, requires elevation.

lewax00 6-Jun-13 12:16pm View

Current user doesn't require elevation.

EDIT: Try it again in HKLM, it won't work. HKCU is intended to be used by any and all programs without admin permissions.

lewax00 6-Jun-13 11:44am View

Depends, what is in DisableTaskManager.reg? Some areas of the registry do not require elevation, others do. Or since you aren't checking the output of of your process, it might just be failing completely and you ignore the error message.

lewax00 3-Jun-13 13:26pm View

I don't think this is the appropriate place for this. Rule 10 that appears right next to the box you typed your question into: "Do not be abusive, offensive, inappropriate,harass anyone on the boards or post ads or spam. Doing so will get you kicked off and banned. Play nice." Specifically the part about ads.

lewax00 22-May-13 17:50pm View

Can you add the code that you generate that value in, and the code from that point to where this function is called (i.e. I assume it's a function, so the point from that function call to the call to this one)? I've seen some similar problems in the past, so it might be related (and if it is, I know how to fix it).

lewax00 16-May-13 16:14pm View

You're probably better off just making the child window part of the Silverlight application instead. I'm not sure how feasible it is to have them communicate directly.

lewax00 15-May-13 14:25pm View

Alright, you seem to have missed the point: we need the line of code it occurs on. The error should mention a line number, or if it shows up in the "Error List" tab, you can just double click it and it will take you to the line the error is occurring on. Add that line to your question (and maybe the whole class or function it's in) using the "Improve question" button. Then we might be able to figure out what's wrong.

lewax00 15-May-13 9:57am View

You asked this yesterday, and I'll tell you the same thing I told you then: we can't help you without seeing the line causing the error. You can re-ask the question all you want, but without the relevant details, no one can help you.

lewax00 14-May-13 18:19pm View

We need more information, specifically the line of code (and related lines) that is giving you this error.

lewax00 14-May-13 17:37pm View

Honestly, it's just too vague. Your requirements will changed based on what you want to do, a "web app for lawyers" could be pretty much anything. Choices like language, hardware, etc. will really depend on the details.

lewax00 3-May-13 17:35pm View

I added something to my solution that may help, see above.

lewax00 3-May-13 17:06pm View

I don't really get what you're trying to do here, but integer division always truncates. So: -5/20 = -0.25 which will truncate to -0, which is the same as 0. As far as checking if a value is negative though, just check if it's less than 0.

lewax00 3-May-13 1:52am View

Are you sure YOU have the rights to do that? You can't very well give a program the proper permissions if you don't have them yourself (e.g. on a work computer, if it's you're own personal computer it's probably not an issue).

lewax00 1-May-13 11:15am View

I'm not familiar with "nltk", but assuming "str2tuple" returns a tuple, you're never creating the second level of the list, you're just appending to "tuplelist". So you'll only end up with a list of tuples. At some point you're going to need to create a new list, append that to tuplelist, then add tuples to that new list instead.

If you want to use C#, then an .html page isn't really an option. C# won't run in a plain .html page. So that leaves you with two options if the file extension matters that much to you: use Javascript, which would require to leave your database open to everyone, some of which will have malicious intents, or write your own HTTP server in C#.

You're closer now. The next problem is this: you still haven't assigned anything (besides 0) to x, y, or z. That's what "a.nextInt()" is for, it reads the next number from the command line. Instead of assigning it to s, assign it to x, y, and z (individually), then calculate s and print it.

lewax00 22-Apr-13 17:58pm View

So what is the problem? Again, without knowing what the difference between what you expect it do do and what it is doing, we can't help.

lewax00 22-Apr-13 17:20pm View

So...what is your question? All I see is a code dump. Please tell us what the program is doing, what you expect it to do, and any exceptions it may have thrown. Otherwise, we probably won't be able to help.

What are you entering for names? Keep in mind, cin.getline null terminates strings, so you actually only have room for 9 characters.

lewax00 9-Apr-13 0:55am View

No, that would index the array to size (5 in this case), which would be beyond the bounds of the array. That would be unsafe code, as you have no idea what's being stored there.

In JS you can declare functions inside of functions, it is perfectly valid.

Have to agree with this, XML is the wrong format to be using when performance is a concern. And files are a poor choice in general if it needs to be able to be edited by multiple threads/processes simultaneously (as it probably would be in the case of a website).

lewax00 3-Apr-13 19:56pm View

I'm not sure I understand the problem, is only one thread completing? If so, have you made sure a) all threads have actually finished executing and b) there are no errors in the other threads?

lewax00 3-Apr-13 17:47pm View

You'll need to be more specific than "have some problems and didn't work connections together". How is it not working exactly? Specifically, what do you expect it to do, and what is it actually doing? Also, include any error messages, if there are any.

lewax00 2-Apr-13 15:52pm View

I'm guessing you either don't have your network/firewall properly configured to allow your phone to access the server (don't ask me how, I've never been good with configuring networks properly), or you're using the wrong address from your phone. Impossible to tell without more details though. (Have you tried pinging your server from your phone? That's always a useful first step for these kinds of things, and there are multiple free apps that can do it.)

lewax00 22-Mar-13 16:52pm View

It's pretty simple: if 1 = 0, then using basic arithmetic, you can prove any number equals any other number. (e.g., to prove 4 = 2, multiple both sides by 2, then add 2 to both sides). If every number is equal to every other number, then equality means nothing. Without equality, even arithmetic is useless. (What's 1 + 1? Anything I want it to be, since 1 is equal to anything else.) It basically ends up with meaning: math is completely wrong (because the rules are wrong) or math is completely meaningless (because any arbitrary statement is true).

lewax00 22-Mar-13 0:53am View

If you can prove that 3 + 5 = 9 though, you might want to write a paper on how, because you could use that to prove 1 = 0, which basically destroys mathematics as we know it...

Right, but unfortunately, as far as I'm aware, the form does not track what steps you took to get the current visual state, so you cannot simple undo a step, you just clear the custom drawn part and redraw it with your new image.

If I asked you how to add an event handler to a button would the answer require instructions on how to click a button to make the event fire? Of course it's required, but it's not what's being asked. Nothing in his question suggests he's having difficulty getting to that point, he's asking what do do once he's already there. If he also has difficulty getting it to repaint, it's his responsibility to ask for further clarification.

In button2_Click, the loop should be "for(int i = 0; i < index; i++)", since you ignore all higher values anyways, then you don't need the if statement. Otherwise, looks good.

It varies from phone to phone, my Droid Razr dropped Flash when I upgraded to ICS and it isn't available in the App Store for me. From what I can tell, if you have Flash, you can continue to use it, but if your phone doesn't have it, you have to install it manually (and in my case, it doesn't work on my phone even then). Additionally, Adobe has announced they are no longer going to develop Flash for Android ( http://www.pcmag.com/article2/0,2817,2406507,00.asp ) Basically, even if you can, unless you only want to support a limited number of phones (and not even the newest ones), I wouldn't recommend it. If it's just for you, you could try, or use the opportunity to learn something new (Flash does seem to be on the way out...).

If you're using it a lot, using dynamic might cause a performance hit (I'm pretty sure it uses reflection, which from what I've heard can be a little slow), otherwise it should be fine (and should even work if you later pass in a custom class, as long as it has an integer property called Length).

In all honesty, you probably can't...not from the float itself anyways. Floats cannot represent every number, in many cases it is only an approximation. You can change how it's displayed however (like Stefan_Lang's answer below), or find a library for scientific/mathematical purposes that allows greater/arbitrary precision (I don't know of any for C/C++, so I can't help you there).

Never mind, you're right, because it increments it before checking it, and never uses 7 as an index.

The assignment seems pretty detailed, what are you stuck on?

lewax00 3-Dec-12 10:56am View

In a few places while accessing C you use "i <= k", this should be "i < k", because the indexes for an array of size k will be 0 to (k - 1). Replacing those should fix that problem I think.

lewax00 3-Dec-12 10:49am View

That sounds like you're writing something after the end of C, it's hard to say without seeing the rest of the code.

lewax00 3-Dec-12 10:30am View

If it's a small program it probably won't matter (i.e. if this function is only run a few times) because the memory will be reclaimed when the program exists, but what is the error?

lewax00 29-Nov-12 14:25pm View

That's not what they were looking for...try reading their question again. Plus your solution adds an extra UserInput1 to the Sum (the first iteration will add that amount, but it was already set to that amount).

Are you sure you really need a Regex for this? Why not just check the length of the string?

lewax00 27-Nov-12 12:21pm View

I love how all three answers capitalize the name of the array differently, but all have the same name. But the use of a variable for the length is a good idea.

lewax00 26-Nov-12 15:05pm View

I don't think there's much he can do about that, it's how scanf works. If you put in a number that large it rolls over into negatives (of course he could check for numbers less than 0, but maybe he wants to allow negative numbers).

lewax00 26-Nov-12 12:57pm View

He told you where it's located, "/boot/grub/". And it's not just one file, but many. Linux does not work the same way as Windows, configuring the boot loader will be a different process. You could probably get better help at a forum dedicated to Ubuntu or GRUB, I'm sure there are many of both.

lewax00 26-Nov-12 12:51pm View

What do you mean "did not work"? Did it fail to compile, or did it not do what you expected it to do? You need to add some more details.

lewax00 25-Nov-12 0:59am View

There's not enough information here to tell, but I'm guessing you are probably trying to get it before it's created. A little more context would help (if I'm right, then specifically which overridden method this is in or called from).

There's a lot of code there so I haven't looked at all of it, but are you sure the calc process is returned by Desktop.GetInputProcesses()?

And just a point of simplification, your method for launching new processes seems a little over done, you don't need to access to Windows API to do it, you can just use the Process class (which you are using in some places), unless there's something you're doing with the Windows API call that isn't done by Process.

Then what you read is mistaken. In an PC CPU a byte is 8 bits. Period. This is a limitation that exists on a physical level. 8 bits only have 256 possible values, and since one of those is 0, the maximum is 255.

lewax00 12-Nov-12 21:37pm View

Well for starters, you can't represent 256 with a single byte...

lewax00 12-Nov-12 19:51pm View

You don't have to convert anything to binary. Everything on a computer is binary already, that's how computers store data (all data, all the time).

lewax00 12-Nov-12 11:56am View

Not sure why it would work with one but not the other, but you can simplify some of this using the System.IO.File class (specifically, ReadAllBytes and WriteAllBytes), the documentation is here: http://msdn.microsoft.com/en-us/library/system.io.file.aspx

Specifically:
FileStream fs = new FileStream(pathold, FileMode.Open);
Byte[] Doc = new Byte[fs.Length];
fs.Read(Doc, 0, (int)fs.Length);
fs.Close();

Can be shortened to:
byte[] Doc = File.ReadAllBytes(pathold);

And:
FileInfo fi = new FileInfo(LaunchedFile);
FileStream fs = fi.Create();
byte[] Data = new byte[0];
Data = ((byte[])doc);
int ArraySize = new int();
ArraySize = Data.GetUpperBound(0)-1;
fs.Write(Data, 0, ArraySize);
fs.Flush();
fs.Close();

Can be:
byte[] Data = new byte[0];
Data = ((byte[])doc);
File.WriteAllBytes(LaunchedFile, Data);

Less steps makes it easier to diagnose.

It depends on the device, for example I install a printer driver as part of a product installation this way:

The total is 16 exabytes (I don't think there is even a super computer today with that much RAM, but I might be wrong). This is assuming that each byte has an address, but addresses may just as easily be for words (which can differ my architecture) so you might reasonably expect as much as 128 exabytes (assuming each word was 8 bytes/64 bits). Of course both of these numbers are ridiculously high for today's computers, but maybe someday we'll utilize it fully.

lewax00 30-Oct-12 12:17pm View

I'm not sure that's entirely true. The compiler also as to store the value, and it probably makes some assumptions about how large that value can be (for example, it seems unlikely that a 32-bit compiler would allow for array sizes greater than 2^32-1).

VB.Net is heavily reliant on the .Net framework, so you aren't going to get any simple conversion from VB.Net to anything that doesn't run on .Net (C#, F#, IronPython, C++/CLI, etc.), but that won't solve your problem from the sounds of it. You will probably have to rewrite your application, unless you can run it on Mono.

So what exactly is your question? You provided a link to a question with a solution, and pasted the solution, but you haven't asked anything.

lewax00 21-Sep-12 13:02pm View

Not sure if it's related to your problem of not, but I'd like to point out in these lines:

u[k].q[i].token_bucket_min_depth = u[k].q[i].MRTR * 1000 * 5/8;
u[k].q[i].token_bucket_avg_depth = u[k].q[i].STR * 1000 * 5/8;
u[k].q[i].token_bucket_max_depth = u[k].q[i].MSTR * 1000 * 5/8;

5/8 will evaluate to 0 as it's written. So all three of them become 0 (0 * 1000 * other value = 0). You should change it to "5./8.", "5.0/8.0", ".625", replace "1000 * 5/8" with "625", or something along those lines if you actually want something other than 0.

From the page he linked to: "When opening a volume or removable media drive (for example, a floppy disk drive or flash memory thumb drive), the lpFileName string should be the following form: "\\.\X:". Do not use a trailing backslash (\), which indicates the root directory of a drive."

There's your answer, it's just used to tell the function you're opening a drive. It has no meaning on its own, just in the context of the function.

lewax00 17-Sep-12 11:30am View

Ah the makes more sense, it sounded as if you were trying to make a file on each machine to store information about the sockets and IPs of all the other machines. In that case you might need to use something to control access to the file you're writing to if each thread writes to the file, or just use a database, because those generally handle multiple incoming writes well.

lewax00 17-Sep-12 11:03am View

That's not necessary, if the grade is 85 it would fails the first condition (>= 90), then the second condition will be checked (>= 80), then it will assign the grade and exit the if-block. Nothing else will be evaluated. Those less than statements are already handled implicitly (e.g. a grade cannot make it to the check for B unless it is less than 90, so that will always evaluate to true in any case the evaluation occurs, because in any case where it is false the evaluation is never made).
