For that kind of stuff, you can use hangfire. There's plenty of code sample available and it's a great tool.

A few things to check:
- have you created the grid columns? if they do not exist it will throw an exception.
- Your casting of values is weird. If the data is not what the code expects it will crash.
- ProductName is a string but you cast it as an integer, if you have a string in the text file it will crash.
- Quantity is an integer but you do not cast it. It is likely to throw an exception.

use the debugger it will be obvious, it is a good opportunity to learn about exception handling.

Once you solve this, it will work.

I guess you are trying to write a selenium test on a yahoo mail page or something ... It's full of scripts! This error means that the element does not exist or has changed or does not yet exist. It's probably due to a script.

See here : http://www.seleniumhq.org/exceptions/stale_element_reference.jsp

Yep! exactly...

What do you mean "And after?"
It's on github with the full source! The question has nothing to do with homework or whatever, it's obviously some guy that has no clue about anything relating to code...

But it's nice of you to take some time to answer him/her.

That would help.
Also, temp tables are notoriously slow... Avoid if performance is a concern! maybe try replacing by variable tables or even better don't use temp tables at all.
In this quite simple piece of code, there does not seem to be any reason to use temp tables, you can get the same result directly.

what about this link?

Just read the readme.md

Nowadays SQL feels a bit like old stuff, there are more modern and flexible ways to access your data. If you google ORM you'll get a few clues. See a general article about it on wikipedia https://en.wikipedia.org/wiki/Object-relational_mapping and a specific article about what is probably the most popular one in the .net world: Entity Framework. See here: https://msdn.microsoft.com/en-us/library/aa937723(v=vs.113).aspx
If you really, really want to use SQL in a .net program look at ADO.net... but most of the time it's not worth it IMHO. https://msdn.microsoft.com/en-us/library/h43ks021(v=vs.110).aspx

Fair enough.

looks like there could be a static property somewhere?

http://letmegooglethat.com/?q=Find+a+sucker+to+do+my+homework&l=1

WPF or Winform?

You have a point but Kendo is pretty nice when used correctly. See my answer below.

Is it OData 4 or OData 3?
If it is OData4 you're in luck as there is a now() function, what you could do is something like month(TimeByDay) eq month(now())-1

Have a look at clientTemplate()
columns.Bound(s => s.CostBand).ClientTemplate("#=Product.CostBand#");

the template can contain any javascript you want... pretty flexible.

You don't, it's a bad idea and it does not work well.
To learn about responsive design have a look at bootstrap for example.

You can try pdf.js it's quite cool!
https://github.com/mozilla/pdf.js/tree/master/examples/helloworld

Look here:
http://www.mikesdotnetting.com/article/230/getting-started-with-asp-net-mvc-5-using-visual-basic

There does not seem to be anything in this code that can trigger this exception. Have you try to debug it? add a breakpoint and go step by step until you find the line that causes an issue.

You could write an extension method that extract formatted lines (or paragraphs)
a line ends in /line
a paragraph ends in /par

Refer to the rtf specifications for details.

Yes I agree with you, it is a bit heavy handed and potentially dangerous but for sake of argument it is possible.
Also from within the clickonce you can do what ever you want, call a webservice exposing the server file system for example.

When you say "There is no way to launch Windows Explorer". This is not strictly true. There are ways round this limitation. For example host a clickonce and activate it, once the app is downloaded you can do what ever you want on the client PC...

For example:
HttpContext.Current.Response.ContentType = "application/x-ms-application"
HttpContext.Current.Response.Redirect(clickOnceUrl, False)
HttpContext.Current.ApplicationInstance.CompleteRequest()

See here: https://msdn.microsoft.com/en-us/library/t71a733d.aspx

ClickOnce is supported natively by Internet Explorer and Firefox and and Chrome using an extension like "ClickOnce for Google Chrome"

Try google or youtube.

for example: https://www.youtube.com/watch?v=HxCq77mrQyo

No worries. Glad you found the problem :)

I can't really tell you the answer as it could be a lot of things... But...

What you need to do is look at the meaning of "Object reference not set to an instance of an object".

Basically it means you are trying to access a property or a method of an object that does not exist.

There are things you can do to make sure this does not happen. For example check for nullity before using a property or method or at least use a try{} catch{}

Also if you run in the debbuger step by step it is quite trivial to find the object that is null... look in the autos window.

I agree 100%. That's the way to go.

This link is so old!! Forget about it!

Instead have a look at codedUI, it is a proper framework rather than some kind of WPF UI automation clever hack...
anyway read here :https://msdn.microsoft.com/en-us/library/dd286726.aspx)

There are millions of google links for CodeUI.

Hello,
You could start by reading the documentation... http://docs.opencv.org/doc/tutorials/introduction/desktop_java/java_dev_intro.html
Valery.

Agree! It depends what you need to do. Another option for a beginner is to use a BackgroundWorker as it is so simple to use.

Sometimes the get is pretty complex and you need to specify what is returned. How would you do it otherwise?
If you want something simpler just use a variable.

yes use a variable for 3 and for 7.

int _min = selectedRange.Min;
int _max = selectedRange.Max;

and use them in the method...

if (e.NewValue < _min | e.NewValue > _max)

I've put the host, password, user and port in the appsettings section. Also I'm in the UK so the server is smtpout.europe.secureserver.net not the US one smtpout.secureserver.net

I'm calm and I did not shout at you... Sorry if you felt offended that was not my intention.
Anyway that does not change the point I was making iTextSharp is not free for commercial projects.

iTextSharp is not free!
For hobbyist or open source projects it is free under the AGPL v3 license.
If you want to use iTextSharp in a commercial product you need to pay for it... Server price is about $2000 per server, desktop price is about $100 per workstation... If you ask me that's quite expensive!
If you want to use version prior to v5 of iTextSharp then you are in troubles as it contains code fragments that infringe on many people's intellectual property and you could be sued...

https://www.google.com/?q=Give+me+any+link+or+Source+Code+for+WPF+Projects+on+C%23

and .net 3.5? .Net 4.0 is not an upgrade from 3.5... As far as I know SQL Server uses 3.5 not 4.0, so you must have 3.5 enabled even if 4.0 is installed.

Is .Net 3.5 installed? I saw that same error happening after .Net 3.5 was removed from a server.

I think someone down-voted some comments you made on an article.

Does the value that has 7 characters start with "0"....?

Hi,
I think you might take it the wrong way round.
What I would do for an existing site is
1)In visual studio create a TFS workspace, copy locally (ie in the workspace) the site files add them to TFS, check in.
2)work with the tfs version of the site, check in, check out, get latest etc... (the other developers have access to the same tfs copy)
3)once your are happy publish the site.
Seems fairly straight forward, you never work on the publish (deployed) site directly.

Why did someone downvote my answer? An explanation would be nice...

Professional UML Using Visual Studio .Net ?

What about pluralsight?
they have literally hundreds and hundreds of good quality training videos. It's not a book but maybe it's good enough?
For example: http://beta.pluralsight.com/courses/vs2010-uml

That seems to be a user right issue. In your setup project you can use a custom action to set the correct rights.
http://msdn.microsoft.com/en-us/library/d9k65z2d%28v=vs.100%29.aspx
http://msdn.microsoft.com/en-us/library/system.io.directory.setaccesscontrol%28v=vs.110%29.aspx

if you need to execute the code that is in the event without firing the event I would suggest you refactor your code and do it another way. for example you could put the code that is in the event in a separate method and call this method where ever it is needed.

That looks like homework to me... Maybe you should try to do it yourself? It's way more rewarding to achieve something by yourself than to copy someone else's answer...

yes it's possible. It's actually the purpose of ClickOnce. Easy deployment, accessible from anywhere.
From MSDN: "ClickOnce deployment allows you to publish Windows-based applications to a Web server, it enables you to create self-updating Windows-based applications that can be installed and run with minimal user interaction."

You did not mention InstallShield in your question. Anyway ClickOnce does not require InstallShield...

I might be wrong but I though ASP.net was compiling the sites using Aspnet_compiler.exe, not the compilers provided by the framework (or at least not directly)

This code is OK and should work.
Have you checked your connection string? are you targeting the same database, same server? my guess is that you have a server/database mix up.

mstsc.exe has two interesting flags:
/admin => connects to the console and does not lock the PC.
/shadow:xxx => connects to session number xxx and shadows a user.

have you tried these?

Yes it will be null... you've just declared the array. you need to fill it with data.
string[] lines = File.ReadLines("malincinsi.txt").ToArray();
string[] ListProductCodeFileLines = File.ReadLines("productcode.txt").ToArray();

Where do you assign data to comboBox1? and what is the content of your text file?
Put a break point on "if (comboBox1.Text == ListLines[i])" press F9 in Visual Studio to set a break point.
Look at the value of your variables and see why if does not work.
String comparison is case sensitive, try "comboBox1.Text.ToLower() == ListLines[i].ToLower()"
Also spaces can be a problem... try "comboBox1.Text.Trim().ToLower() == ListLines[i].Trim().ToLower()"

What is in your variable "a" ?

Hello,

Actually I think it may be possible using OpenXML. When the document is rendered, each rendered page break in the document object model is marked with a LastRenderedPageBreak. see here: http://msdn.microsoft.com/en-us/library/documentformat.openxml.wordprocessing.lastrenderedpagebreak(v=office.14).aspx

You need to delete all the elements between 2 LastRenderedPageBreak. This is where it becomes tricky as LastRenderedPageBreak can be anywhere in the document elements tree and you'll need to re-create a coherent tree.

I think it might be quite a complex task!

That does not work... only the active tab has it's MainWindowTitle set. All the other processes have an empty window title.

A web application is not a desktop application? Can you explain what is the reason to do this conversion?

Yes you can use it. It is "marked" as deprecated but it is still there... actually it is still there in .net 4.5

Extract form the Microsoft documentation:
The .NET Framework and the common language runtime strive to support backward compatibility (allowing applications that were developed with one version of the .NET Framework to run on the next version of the .NET Framework). This makes it difficult to simply remove a type or a type member. Instead, the .NET Framework indicates that a type or a type member should no longer be used by marking it as obsolete or deprecated. Deprecating a type or a member involves marking it so that developers are aware it will go away and have time to respond to its removal. However, existing code that uses the type or member continues to run in the new version of the .NET Framework.

If I were you I would start with the basics and read about exceptions... Here's a good starting point: http://www.codeproject.com/Articles/125470/Exception-Handling-for-C-Beginners

stamper.setPdfVersion(PdfWriter.PDF_VERSION_1_4);

Where is the code to correct?

What have you been using? Can you show us some code?

Installshield is big piece of junk! If you have the opportunity to use anything else then consider changing!!!

Where are you stuck? for copy-paste see google.

Use FireFox, go to Add-ons, search for youtube... the first 300 ish result download youtube videos.

2 good advices!
buy one, get one free :)

I guess some server at google must be able to load your file to display it. LocalHost is visible to you only, you should provide a public URL rather than a local one.

I love Linqpad! such a great tool! and plenty of example of the c# in a nutshell book available. It's a great tool to use and a great tool to learn.

https://www.google.co.uk/?q=how%20to%20create%20a%20setup%20file%20in%20visual%20studio%202010

Yep! That's what I would do :)

simple and easy :)

It's not really a programming question...
A way to do it is to configure your firewall for example: http://www.trishtech.com/2010/05/block-a-program-in-windows-7-firewall/

good to know :)

Maybe you should ask once only ???

And... what do you want? sorry but I don't get it.

Reason for my vote of 5 \n Really good tip. I'm currently doing something similar in the process template xaml definition. I'll refactor using a t4 template, it's a really good idea. Nice and clean :)

well... what have you tried? and in which language?

look at http://msdn.microsoft.com/en-us/library/System.Windows.Annotations.AnnotationService.aspx

http://www.codeproject.com/Questions/655899/check-at-input-type-of-user

I don't think that the right attitude when you find something boring to search is to ask someone else to do it for you... If you can't be arsed making an effort don't expect others to do it for you.

Wow! it's more than just a question... it seems you need to learn everything.
Google is full of resources. A few good places http://www.w3schools.com/aspnet/ or http://www.asp.net/ or http://msdn.microsoft.com/en-gb/vstudio/cc136611.aspx

you can always go to http://writemyhomework.org/ and ask them to give you the answer :)

Where is the code to export to Excel? What you are showing here is just he code to send an email with an excel attachment. It's not possible to help you if we can't see the code where the problem is.

Why would we do that? Most people here are happy to help if you are stuck on a specific problem, or if you don't understand something. They are not here to do your homework.

What is the code in the constructor of Data_Con?

Very good but .Net 4.5 only which rules out Windows XP and Server 2003.

I have the same issue but the other way round! vs2010 unloads all the projects from the solution, it happens only on one Windows server 2012, all other machines are fine. I never really found what the problem is.

The problem is that there's a huge fixed size width for the label and he's right aligned then in the CSS:

form.register label{
color:#444;
width:198px;
float: left;
text-align: right;
margin-right: 16px;
margin-top:2px;
}

So even if the form is centered, the CSS for the labels will push everything to the right, and it will look weird.

That seems quite expensive!... Did you look at the Standard rather than Shared option in the calculator, it mentions up to 500 websites. It does not calculate the price on the number of sites, but on the size and number of Virtual Machines. I guess 1 machine should be enough for you... It is still expensive at nearly $900 a year, but I guess you can run quite a few small sites from the VM.

Here's the best link ever: http://www.google.co.in/search?q=adventure+works

Do you use Visual Studio? Which version? What did you use to create the installer? Can you give a few clues?... It's difficult to guess with so little information.

Hello.

use a httpwebrequest:

HttpWebRequest webRequest = WebRequest.Create(@"https://maps.googleapis.com/maps/api/place/search/json?location=52.00,1.1957362&radius=7500&types=restaurant&sensor=false&key=yourkey") as HttpWebRequest;
webRequest.Timeout = 20000;
webRequest.Method = "GET";
webRequest.BeginGetResponse(new AsyncCallback(RequestCompleted), webRequest);

and in the call back parse the response:

private static void RequestCompleted(IAsyncResult result)
{
HttpWebRequest request = (HttpWebRequest)result.AsyncState;
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(result);
string response = string.Empty;
using (Stream stream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(stream);
response = reader.ReadToEnd();
}
}

The response string will have something like:
"results" :
...
"geometry" : {
"location" : {
"lat" : 51.8664050,
"lng" : 1.2132110
}
...
"name" : "King of spices",

write a class to parse the response and load in the listbox the info you like.

5 :) I read once a quote from Bruce Schneier on that subject: "Digital files cannot be made uncopyable, any more than water can be made not wet."

Why did you mention the webbrowser control?

A hosted VM is a virtual machine, basically it is like a normal server, except that it is somewhere in the "cloud" and you don't have to worry with hardware failure or internet access etc...

Visual Studio.

Did you try to type in google "triangulation library"... and try out one of the 1 million results.

I don't understand. Have you got some code already?

What do you mean? what do you want to do? display it, change it? can you clarify?

You can do that in 2 easy steps... Read about Timer, try coding something... It should not take more than 10 minutes.

Point well made! There are things that are off-limits... 5

What a silly assignment! I don't think that using riddles to teach programming is very clever... lewax00 solution points you articles showing how to format outputs.

Although Cisco contributes to a few open source projects, as far as I know the Cisco routers os (IOS)is not freeware and not open source. By giving the source away you most likely commit a crime and I think you may be in troubles... The only exception I am aware of is the that after purchasing Linksys, Cisco had to give away the sources of the WRT54g Os has it used some open source components, but cisco was quite quick to close the loophole.

I quite sure that nobody will give you this here...

What does this mean? Can you clarify?

Without seeing any code it is difficult (or impossible) to know what's wrong...

CurStep let's you select at which point you want to perform the operation. CurStep=ssInstall means just before the installation starts,CurStep=ssPostInstall means just after the installation finishes CurStep=ssDone means just before Setup terminates. Anyway happy that you made it work. :)

Thanks. ;)

The exception you asked a question about was "cannot convert type string to system. mail.attachment", that's fixed. What is the error you have now?

Hello,

< html type='application/msword'>Hi < /html> won't work.

<html type='application/msword'>Hi </html> does work.

There should be no spaces in your html tag.

Valery.

Hi,

I've just tried the only demo of the editor and type the following html code in it : <strong>Hi</strong>

I then modify this text (not in the editor, in my code...) so that it looks like that:

<html type="application/msword">
<strong>Hi</strong>
</html>

Save that as Test.Doc, and open in word, it renders correctly, everything is fine in Word.

Could you describe your issue with more details please, maybe show some code?

Valery.

my pleasure :)

Thanks :)

Could you show us some code please?

Is that C#?

You beat me to it! :) 5!

A very good and detailed answer! it's a 5 :)

By the time I posted my answer 3 other answers were posted! :)

your question is a bit confusing, could you show us some code?

The answer is in the article you are using! Use compressed video.

I have seen that wikipedia link somewhere else :) I must bookmark it!!

Hello,

Mapforce allows you to generate a c# program that will convert an xml file from one schema into another. That is the purpose of this software!... there is menu in it to generate a conversion program in most popular language... it is kind of difficult to miss it!

I suggest you read about mapforce or maybe try to use it.

What is your question about?...

Valery.

I suggest you read a few books or maybe spend some time studying with websites like http://www.w3schools.com/ or many others... or aps.net as previously mentioned!

sure... everything is possible but it will take a long time!!

Hello,

You could have used "if (e.KeyCode == Keys.Left)" but otherwise it is fine, this code is correct, the problem must be somewhere else.

Valery.

did you add at the beginning of the file : using System.IO ;

On the Reflector toolbar there is a dropdown where you can select the .Net language you want to use for the decompiled code.By default it is set to C#, if you select another language you will see the code in this other language.
As far as I know, there is no obvious and reliable way to tell what is the original language, other than vaguely guessing.
What do you mean when you say "check how the packages are added"? Do you mean the references? that is independent from the programming language.

very good link.

Spot on!

When I was learning my job I use to do my homework myself...

Thanks. Your solution is nice and simple, I've never done it this way. I'll give it a go ;)

Thanks :) Valery.

I find it's quite funny that last week survey was about brackets!
http://www.codeproject.com/Surveys/1156/Do-you-wrap-single-line-statements-in-braces-or-be.aspx

Look for MSB3097 on google... that should point you in the right direction to fix this error.

Oops! I did not notice you had already answered.

Then look at Manfred's answer (#4):

for (int x = 0; x < pictureEdit1.Image.Height; x++)
{
for (int i = 0; i < pictureEdit1.Image.Width; i++)
{

That will solve your issue.

Maybe I wrote a bit too quickly, anyway. voting 1 is a bit harsh!

If you have somewhere else in the code something like:
while(backgroundWorker.IsBusy)
{
// some code...
}
I experienced that adding DoEvents() in the loop will make backgroundWorker.CancelAsync() work, otherwise it might not work.

while(backgroundWorker.IsBusy)
{
// some code...
Application.DoEvents();
}

Did you change your css as well? Note that the "=" signs have been replaced by ":".
If you apply both changes it works very well. ie the ":" in the css and <link> instead of <style>.
I vote 5 for Manfred solution.

I've got the same problem an another thing I have been looking at for my application is replacing the webbrowser control by an open source .net wrapper of webkit.
