Re: Please, need urgent help. Application wont start (clr20r3 error) - C# Discussion Boards

Yes. I have included an installer with prerequisities : .NET Framework 2.0, DirectX 9.0C Redistributable, DivX and XvID codec. I think that the application only needs this software.

OK - well, it seems to me you must be missing some dependancy, for it to work on some PCs and not others.

So, how can i fix that? I would be very greatful if you'd take a look at the source code :/

It's very very important for any developer to troubleshoot:

Add in a small routine to write to a log file or popup a messagebox for debug purpose. You can remove them in in the production version.

1. Has your application started at all? Add a debug message as the first line to execute. If the application has not been started at all, it should be due to missing dependency or the environment (.NET instalation etc).

2. If the application started, add in the debug message before and/or after the area where you think it may cause troubles. Slowly drill down to narrow down the trouble area.

3. Additionally, put a try catch block at the Application.Run and catch the exception and save the trace message to a file. You can read the trace message and try to find out where it went wrong.

The problem occurs when the user clicks on .exe file. Thats it.

And i have a problem, that the application works at my computer, only at some computers doesnt work :S So i cant test the application.

I thought that you can get at least some information out of the error log?

Click on View Detail, on the View Detail popup, look at the first line of StackTrace and see where is the line at which the exception is thrown, then drill down from there.

Seems to me there's something wrong in your frmIME. You should step into the code of the initialization of that form (F11) and see where it went wrong.

Hi.

I did what you suggested.

Here is the copy of the error that was given. Not sure i quite understand how to fix it, since the problem is, as reported, in security??

What to do next?

Oh, and is there a possibility to use the DLLs from my computer? I only use the DirectX.AudioVideoPlayback.dll (i think this is it, cus VS copies this file to the debug output as asked).

Hey guys...

this is a bit of a brain fart... but is it possible to have more than one condition in a case statement?

eg...

switch (myString)
{
     case "hehe" || "haha":
        //do something
        break;
}

thanx

Why don't you give it a try? If you are lazy opening Visual Studio for such simple tests, you can use snippet compiler, it's quite a handy tool.

How to insert data to a table in the database by using c# language?

hi,
read the Code Project Articles[^] and Googling[^]

Well, the trouble with your question is two fold

1 - we have to ask ourselves if it's worth helping someone who is unwilling to invest in a book, search the web, or show any signs of having tried to learn for themselves
2 - even if we were so inclined, we'd soon find that any help we tried to give would be limited given the typical length of a forum response, and the amount of detail required to properly cover the topic.

I recommend you read the article linked to in my sig, then type C# database insert into google. Typing the name of your database ( such as SQL Server, Oracle or Access ) will give you even more specific help.

cc is my ConnectionClass object.
cmd is SqlCommand object.
con is the object of SqlConnection

cc.cmd.Connection = cc.con;
cc.cmd.CommandText = "insert into tblName ([col1],[col2],...) values ('" + val1 + "','" + val2 + "',...)";
cc.cmd.ExecuteNonQuery();

I want to load treeview nodes in background. Information about them are stored in an xml file
<node some="" info="">
<more info="" />
<subnode sth="" else="">
</subnode>
</node>
etc.
This file can be quite big and computers can be quite slow. So, I want to have a repsonding UI and TreeView items should appear one after another.

Of course, I did something, but it is dangerously close to a WTF zone. That's it:

1. Start some Load method in a new thread.
in the Load method:
2. Handle Menu.OnNodeLoaded event -> menu_OnNodeLoaded.
3. Call a function which reads data from a file, sth like. Menu.FromXml(...).
in that function:
4. Iterate throught an xml file.
5. Create a MenuNode object, which contain a Path property, e.g. "node/subnode"
6. Fire OnNodeLoaded.
in Window.menu_OnNodeLoaded:
7. Iterate through menuNode.Path to find a TreeViewItem place where a new TreeViewItem should be added.
8. Create a TreeViewItem and add it to the treeView.

How to do that better?

Portable.NET is part of DotGNU, a project to build a complete Free Software replacement for .NET - a system that truly belongs to the developers.

I'm trying to draw a line on the form in C#.
When i place the below draw line code in Form1_Load() method it does not draw the line when application starts. But if the same code is placed in Form1_Paint() method it works.
System.Drawing.Pen myPen = new System.Drawing.Pen(System.Drawing.Color.Red, 5);
System.Drawing.Graphics formGraphics = this.CreateGraphics();
formGraphics.DrawLine(myPen, 10, 10, 150, 200);

Why does the code not work in Form_Load(). Is is required that all graphics code needs to be executed in Form_Paint() method only?

Well, probably because in one case you did it properly, and in the other, you did not. CreateGraphics creates a graphics object that is invalidated the next paint event. So, it's for drawing temporary things. Forms are always invalidated after the form load event, so your code was never going to visibly work.

Thank you for your answer. Well i have another problem. On the form i have a groupbox. I want to draw line inside the groupbox. How can i do this?

you'll need to handle it's paint event and draw your line.
