Right off the bat, ftpServerIP + "/" + fileInf.Name); will attempt to save "/fileName" because your ftpServerIP string contains a trailing /

Is "/" a valid character in a filename? Pretty sure not.
GenJerDan 21-Dec-20 5:03am View
   
Me, if I was sure the extra characters were non-text/non-printable, I'd add a "trim" in there somewhere to remove all extraneous characters from the ends. That's cheating, of course.

Yeah, I went with if/else. Simple, if not fancy. And it's working, which is all that Higher cares about. LOL
GenJerDan 17-Dec-20 10:06am View
   
That's my understanding of it, too. I just get nervous diddling with a live system. An example I found on the web has:
class Example {
static void main(String[] args) {
int[] array = [0,1,2,3];

for(int i in array) {
if(i == 2)
continue;
println(i);
}
}
}
in which everything gets printed except "2". I just wasn't sure if that would apply with a .eachFile loop, or if it's only good in vanilla "for" loops. That's from the documentation. S.O. is all over the place with answers, some saying "return", some saying "continue".
The divide seems to be "for" versus ".eachXXX" loops, with .eachXXX liking "return" best.
(I'll come back an Accept Solution once I try it out, if I don't get a more definitive answer. Thanks.)

Upgrades are not allowed until vetted by The Powers That Be. No updates to anything have occurred in months. (Closed system, all updates are manually done.)

How would LIKE work on a number? Is 3 like 13? Or is 4 like 3, only a little bigger?
Anyway, check out CAST and CONVERT and turn the number into a string and do the comparison on the newly converted string.

Where is the MDF located, and are permissions on that location set correctly?
GenJerDan 2-Apr-20 9:01am View
   
It also assumes all sorts of things which may not be true. There are many family names which are two or more separate "words", and probably a few given names. Getting two initials just became more complicated. If it really needs to be two initials, the code should take the first word and the last word in a split string list, and process those for the initials. (This will also work just fine for the simple case of two "normal" names, of course.)

I would say do NOT check availability on any domain-name site. Even legit ones. Unless you buy the domain immediately, the chances are good that someone else will buy it up and try to sell it to for the low-low-price of twice what it would have cost if you bought it immediately. I've been waiting for years for the jerk who bought up my preferred .com name and just has it parked.

Maybe just doing a web search for the domain you want, would at least tell you if it's already in use somewhere.

And, unless I'm not thinking clearly, that code will wind up only displaying the last instance that meets the conditional. Well...they might all appear, but you won't see them becasue they'll fly by really quickly. ;)

Heck with the breakpoint; put in an else (temporarily) and show what actually is in the TextBox. (In the meantime, Trim both the TextBox and the Clipboard text, and do a ToUpper or ToLower on them both (or otherwise de-case-sensitize the compare)) ;)
GenJerDan 26-Apr-18 2:22am View
   
If the form you're trying to close is the "main" form of the application, closing it will close the application itself. You're better off hiding it (you can close other forms, if there will be more following this pattern), or trying doing the whole thing differently. Have to you looked at any examples of "wizards"? Wizards do something close to what you seem to be wanting to do.

Since it looks like only a readonly preview is being asked for, how about using a PreviewHandler? https://www.codeproject.com/articles/18202/photoshop-preview-handler-for-windows-vista

Or am I missing something?

Thanks. That looks like it will provide more info than the Failed Request Tracing, which doesn't say much at all.

I wish. But we are constrained to work with what is. Maintenance mode, for now. That would involve New development.
GenJerDan 2-Sep-16 12:45pm View
   
It's in the pipeline; we just don't have the people to get everything done that needs doing in a timely manner. :(
GenJerDan 2-Sep-16 12:40pm View
   
I think the crashing is just as likely to be related to taking too long combined with a few dozen similar processes running at the same time. The Daily Upload of Data, all occurring at the same time, via this sort of ridiculous ASP/VBScript...thing.
We're in the process of converting at least this part to an SSIS, but we keep being overcome by circumstance; too many fires and not enough firemen.
IF there is an actual error, it doesn't show anywhere, and I don't have enough knowledge to put any decent debugging code in these things. And, of course, we are not allowed to install any tools on the servers.
I can say what the problem isn't: there's nothing wrong with the text files that are loaded. Running the process two or three times eventually gets all the data processed. And it's not even all that big. The files combined come out to be about 83K lines total.

Caret-delimited text, like^this.

D'oh! Yeah. Got a CheckBox UserControl, too. :p

And, yeah, I think it probably is the UserControl gobbling that part of it. Well, no matter, since this isn't a "real" thing. Might be fun to figure out how to "reexpose" it.
GenJerDan 15-Oct-13 11:23am View
   
Except for the pretty forms, it's a simple database app. I'll just set everything back to "Form" instead of the custom class first. If that doesn't do it, I'll grab the machete and start trimming... :p
GenJerDan 15-Oct-13 11:13am View
   
Not just my system, though, so it has to be the code. I'll go in and cut out all the "extra" stuff and see what happens. It's probably going to end up being the code uswed to pretty-fy the forms. That'll teach me to go to CodePlex for things.
GenJerDan 15-Oct-13 11:11am View
   
Not a dang thing. I've been "skinning" the forms, but took the skin off the one calling the dialog, but it made no difference.. I'll try de-skinning everything and see if there's something in there doing it. Have never gotten an error (at least that would point to where the problem is). Oh, and it happens with or without debugging, and inside or outside VS. I always seem to get the weird problems...
GenJerDan 14-Oct-13 20:32pm View
   
Yes. Tried with and without. No difference.
GenJerDan 14-Oct-13 20:32pm View
   
How do you screw up a MessageBox?
if (MessageBox.Show("Really delete this entry?", "Confirm delete", MessageBoxButtons.YesNo) == DialogResult.Yes)
{ etc.

That's System.Windows.Forms.MessageBox

Now that one, I didn't include the owner.

But for the FolderBrowserDialog, I did.

But there's not much to show, code-wise. I dropped the dialog on the form, not created in code, so all I'm doing is:

if (dlgFolders.ShowDialog(this) == DialogResult.OK)
{etc.

And it behaves the same whether or not there's a "this" in there.

I guess all this means is no else has ever seen this before. Googling shows other people...who fixed it by including the owner. Made no difference on mine.
GenJerDan 14-Oct-13 16:02pm View
   
What it is doing is main form "Form A" opens "Form B" modally, which pops up the FolderBrowserDialog modally when a button is pushed. I have not explicitly created any threads. Is Windows/VS doing it behind my back?
GenJerDan 26-Sep-12 9:06am View
   
It's not restricting the application. It's restricting the use of the entire computer on the network. Logons are already restricted via Active Directory. It's a legal requirement that the users agree to the terms of use once a year. Anyway, I found a solution.
GenJerDan 25-Sep-12 9:09am View
   
Nah. It's just the standard Gov warning. Same thing, pretty much, that pops up if you go to a government website.
And (and maybe I should have said this) it only pops up once per year. If the user agrees, they're good until the next year.
GenJerDan 24-Sep-12 19:57pm View
   
Not the usrer's computer. They belong to the Federal government.
GenJerDan 24-Sep-12 16:33pm View
   
Unless the user agrees to abide by the agreement, they ARE NOT ALLOWED to use the computer. If they don't like it, they can find another job somewhere else.
GenJerDan 24-Sep-12 15:14pm View
   
I guess I explained it badly. It's to prevent users from the using the computer, not just an app. It's essentially an additional log on screen for the system. (I'll edit above to clairify.)
GenJerDan 10-May-12 9:16am View
   
Whether "modal" is tyhe right term or not...don't know. But if I have three popups that need to be shown sequentially, the second has to wait for the first to finish, then it would pop up while the third waits. Then, after the second is done, the third can annoy the user. In a previous incarnation of the app, I used ShowDialog on the popup (which was just a regular form with some animation) and it worked fine because ShowDialog didn't return until it was done. This form uses ShowWindow (grrrrrr), so it "returns" immediately and the second and third appear before the previous one(s) are done. I'd have to go back to the old popup...if I can find the code...this one is SO much nicer.

Isolated how? Where would you put the the controls so they aren't wrapped in the master? Don't you put them in the Content areas?

I've had IIS "magically" decide to disable authentication and revert back to Anonymous. If that happened to you and you had your app set to Deny anonymous...it wouldn't work. What, exactly, is the error you're receiving?
GenJerDan 29-Aug-11 11:16am View
   
Talking too long in filling out a page shouldn't cause a Request timeout. If anything, it would be a Session timeout, which has a default of 20 minutes (unless the hosting provider changes it). The Request timeout is probably from whatever you're returning to the user after they've submitted the page, or while attempting to insert the data into a database (assuming that's where it's going). Any error codes at all being returned?
GenJerDan 29-Aug-11 10:01am View
   
You're welcome.
GenJerDan 25-Aug-11 15:57pm View
   
Check with the author if there's an updated version. Although I don't know why it wouldn't load in 2010. At worst, it should do a "convert" on it. Also, a search for "C# MHTML" will bring up a cople of pages worth of links, including: http://code.msdn.microsoft.com/Creating-a-MHTML-MIME-HTML-61cf5dd1 which might be what you're looking for.
GenJerDan 24-Aug-11 16:12pm View
   
OK. That's just weird. You get "500" on the regular pages (an IIS Internal Server Error), but 200/206 on the video file (which is ok).
GenJerDan 24-Aug-11 14:25pm View
   
If your network blocks MSDN and ASP.NET, then you really need to have a chat with them, since they are preventing you from doing your job.

Gosh. Sounds like a scary world, that WEB DEVELOPMENT place. Glad I live here.

Check the Event logs (Application) on the server. If nothing there, check the IIS logs, see if you're getting anything but a 200.

MSSQL 2005, No primary key (it would be a combination of multiple columns if I could do it...but I don't own it). As far as which columns match...all, except the one that can differ and one differentiating the rows. I can deal with that. Thanks.

It's not so much the CASE that would give me problems, it's the comparing two rows. The only way I can think of is to split the table into two temp tables and compare them row by row, selecting the proper row based on the criteria to return to the app.
GenJerDan 19-Aug-11 9:49am View

GenJerDan 15-Jul-11 14:33pm View
   
It probably isn't an issue in this case, but for the future: beware of your ending date. If there is any possibility that the time portion of the DateTime won't be null, that <= 7/15/2012 won't get you the ones born on the 15th in most cases.

Safer to add a day and just do a less-than, i.e. < 7/16/2012
GenJerDan 14-Jul-11 14:09pm View
   
well, then your added parameters don't match your declared parameters. Change them to @image_type and @image_size and see what happens.
GenJerDan 14-Jul-11 9:17am View
   
Never mind. I was thinking the sql string was getting managled from the ( being up against the rest of the text, but that's not the prob.
Is this code copied directly from your program? If so, @imagtype and @imagesize are incorrect, spelling-wise.
GenJerDan 13-Jul-11 16:49pm View
   
You just need to parse and replace some characters. For instance, if it returns 5.25E+12 do a .Replace("E+"," x 10^") on the string, which should reformat it to "5.25 x 10^12"
GenJerDan 14-Jun-11 9:22am View
   
Nope. The delay won't be the data transfer from the server. It will be the rendering of the grid. I've run into this way too many times in past, even with grids of only 1000 or so records.

The best way to do is to only retrieve enough records to display on a page, then fetch more as the user wants to see more. (There are a lot of examples here and elsewhere showing how to do that.)
GenJerDan 13-Jun-11 15:00pm View

Accepted because it is tacky to provide my own solution, even though it had nothing to do with either. Problem actually solved by Brian Eno and a cigarette.

True or False, made no difference. AutoPostBack is set on the combos. It's acting like it's not a web app. Yes, I even tried running "Convert to Web Application" on the project. No diff. "Normal" HTML controls work just fine, i.e. a hyperlink will bring me to a new page. Driving me crazy.

Deja vu all over again... More info needed:
Does the player show up on the page, but no media in it? Or is there no player at all?
What does the source look like when the web page is rendered (View|Source in IE), meaning: Is the URL of the media correct?
GenJerDan 19-Apr-11 9:21am View
   
EVERY time I couldn't get a video to play it was because the URL was incorrect. Are you really getting the URL you're expecting?

I'd try a tiny test program in another language (C, C++, VB) that does nothing but the function you're having problems with and see if you get the same or a different error. But even before that, I'd put breakpoints in your existing code where you're connecting to the card...see if it really is getting connected.
GenJerDan 18-Apr-11 12:31pm View
   
Yes. But one of the posters mentions that the results are different when called from .NET and "regular" programming. Like the DLL isn't returning the datatypes expected, so the actual error may not be card removed, but something else entirely...

Well, if none of the results have a groupType 0 - 32, then the distro lists are not in OU=Groups. You can either find out which OU contains them, or back the query up one more level and search the entire OU=NetworkLocation. I'd only do once, though. Then look at the distro lists and see which OU they are in for future queries.
GenJerDan 7-Apr-11 9:49am View
   
The query is wrong. It should NOT start with "CN=". That's just looking at a particular object, not an OU. Cut it back to the first "OU=". If you don't have a way to browse the Directory (I use ADSIEdit.msc) to find where the Distribution Lists live, check with the Domain admin folks. They should have the info.
GenJerDan 7-Apr-11 9:31am View
   
DLs are just groups, separated out either by OU or the flag I mentioned above. Can you give an example of what you're seeing and what you expect to see? Outlook shows the displayName. It may differ from the cn and will surely differ from the distinguishedName. :^)

Ah. I guess they need to be embedded somewhere "upstream" of them being applied. Good to know.
Actually, the easiest way to do all this is to design your doc in Word, save it, then use the Document Reflector to deconstruct it into a C# class.

Well, if it's not the Subject or the sender tripping the junk alarm, it's probably the content of the email...or possibly lack of content. Another junk indicator is an HTML body without the plain-text version available.
A "good" HTML bodied email will have this in the header "Content-Type: multipart/mixed;" and then the body will be available as both "Content-Type: text/html;" and "Content-Type: text/plain; "

Probably some other security setting, but don't know. Windows & IIS have both locked themselves down pretty well as far as access to the drives/network go. I don't have IIS here (and not v5, anywhere) so I can't investigate further at the moment.

OK. That's ridiculous...maybe. If I *DO* run the setup as Admin, the app works just fine from that directory for everyone. Guess that would have been nice to put in the documentation and How-Tos. <sarcasm>Thanks MS.

The setup isn't specifically running as Admin, but yes, it apparently does it anyway or it's inherited because of the location... Looking at other apps in that directory, they're all owned by System or Administrators with limited access to anyone else... So how do the other "anybody" apps read and write there if they're not running as admin? I have to elevate in my app?

". . .as if HTTP Server hosting ASP could help to implement SMTP somehow, which is not the case."

Not to hijack or anything, but I'm doing something not disimilar and wonder if this is more efficient than doing the for loop above, since the loop will run its entire course, even if the first extension hits.

Then you are having a different issue. The above code is correct. Looking for a file called "WhateverYourAppIs.exe.config" in the output directory of VS (Debug, hopefully) and see what's inside. It should contain the last changes you made to the settings. If not, then you are not calling the .Save() method in the right place or at all.

While they (all the ones I checked, anyway) will work, they don't actually create a Word doc. They just "trick" Word or Excel into opening what you send it. That is probably fine in most cases...but not if you need a "real" doc for whetever reason (formatting, etc.).

It does the same as Answer 1 above, takes the first date and the very last date and uses them, even though there are dates between which are not adjacent to each other. My orginal Q sucked, because it wasn't clear enough.

Thanks, but that didn't do it. It collapsed all the dates, not just the adjacent ones. For instance, if the dates were 11/20, 11/21, 11/22, and then again 12/13, it set the start as 11/20 and the end as 12/13, whe what I need is 11/20-11/22, and then 12/13 standing alone. Maybe my question wasn't clear. Sorry.

Thanks. Unraveled it and put a break in...but it seems canceling a backgroundworker doesn't actually cancel much of anything until it feels like it, so it didn't make a difference. Sigh. Guess the app is as tweaked as it gets. On to writing the help file. Yecch.

If ClaimID is an int, why are you converting it to a string, then back to an int. And if it's an int, why are you passing it to the SQL as a varchar?
Anyway, are you setting breeakpoints when running in debug mode to see what the value is during all this? Maybe you're not getting what you expect you're getting.

Not putting this in as an answer, but I've had better success doing something like this:
views.SetActiveView(TheViewIWant);
rather than using the index.

Are you absolutely sure you wouldn't rather do this on the underlying datasource?

Tried three different methods: enumerate all the files, then filter them; filter them while enumerating them; and using .GetFiles instead with the filtering coming afterward (LINQless).
The difference was a couple thousandths of a second on 4000+ files, and even that wasn't consistent in which method was "fastest". Lesson learned: it don't matter worth a darn which you use. :^)

Which I will, if no one already knows the answer off the top of their head. But why do it if someone else already did it and will share their experience?
If no one has, no problem. And I'll drop my results in here in case someone else ever needs to know.

Well, that's...not optimal. :^)
I wonder if we could make an add-on that'll detect the video stream and throttle it severely for a few seconds to "fool" the initial buffering. Hmmm....

And, just in case anyone is interested, the app won't blow up if "using" the WMP control if it doesn't exist on the box. It just ignores it the reference. Had to put in VMWare and an N version of Windows to find out, but there it is.
GenJerDan 30-Oct-10 23:25pm View
   
But I don't want it to be an error, per se. I'd rather give the user a choice between using WMP, if available, or a VideoLan (which I'll include with the app), if not.

Looking in the registry for WMP will work, I guess. Don't need special permissions just to look, hopefully. :)
Meanwhile, Googling brought up a mention of "Managed Extensibility Framework", which is overly complicated for my purposes, but interesting...maybe in version 2.

As for not seeing the ActiveX...I wasn't seeing a ListBox, either, so something about the way I'm calling the form in the DLL is just plain wrong...and I can find no samples of how to do it. No samples that work, anyway. :(

Ah, ok. I'll just set them to 500 and hope for the best. If anyone runs up against a shorter limit, I'm sure they'll let me know. :)

The Comment and Keyword (Tags is the friendly name) I'm asking about are the ones you get if you right-click a file and select Properties | Details. Is that the same structure?

17,000 at the moment...if I did a full gathering, it might be twice that. Never got the hang of paging and such, though, especially when he user can sort the data anywhichway.
I ran up a version using what we've spoken of and it works without a hiccup, so I guess This problem is solved. Thanks!
I may change it to use the record number (an actual id field), rather than the filename when it comes to the find-and-change-color part. I don't know if it makes a difference, but finding an integer match might be faster than finding a string match. I'll test it both way and see if it matters.

Oh, yeah, another thing which others might find helpful in other situations: I *do* run this in the debugger, and it never complained about it until recently...when I went from 10 rows in the underlying table to about 17,000. So it really really pays to test things with the expected data, not just a handful of test data.

Wondering: would I also be better off checking the existence of the files directly from the underlying table, instead of via the DataGridView? The table won't change very often, and if the user *does* want to change it, I can kill the thread and run the process "next time".

Then use that list, as you said, to change the grid in the UI thread.

The thing was threaded just so the user doesn't have to sit there waiting and waiting and waiting while housekeeping is being performed, but it's not overly vital that it takes place uninterrupted every time the user starts the app.
