the project consitutes 5 dlls namely
appstart.exe
appcontainer.dll - a container that holds all the user controls
comms.dll - database layer
basectrl.cll - the parent template
screens.dll - all the user controls this is a main project that i work on.
frmContainerThreadExceptionHandler when thrown logs a exception detail into database. but for this exception it didnt log a exception.
why do you think upgrading .net 2.0? do you think it might fix this memory leakage problem? if yes how can i do that upgrade? i currenly run all project in visual studio 1.1.
thanks for all your help so far.

From the exception's traceback I can see it crashes inside frmContainerThreadExceptionHandler,
so if you don't see it in the database, it did crash before you write it out.
Try adding a Console.WriteLine(myException.ToString()) at the very start of the exception
or something similar (maybe just write to a new text file).
I see frmContainerThreadExceptionHandler is trying to create an ErrorForm and failing at it;
can you show its constructor code?
For a big project having problems I would consider upgrading to 2.0 since a couple of things
have improved, I recon exception handling is one of them. Anyway, I don't expect MS to
fix all bugs they still find in all older versions. If you decide to do it you will need:
- Visual Studio 2005 (the free Express Edition or other);
- 2.0 versions of all third-party stuff if any;
- to reopen your project and let the wizard convert it;
- I expect 99% of code to be compatible; a few classes got their method names or signatures
modified, the first build attempt will point them out.

Hi!
below is the code
-----
Private Sub ThreadExceptionHandler(ByVal sender As Object, ByVal t As System.Threading.ThreadExceptionEventArgs)
' This is our default, catch all exception handler
' get the stacktrace object for this exception
Dim stack As New System.Diagnostics.StackTrace(t.Exception)
Dim i As Integer
Dim files As New Hashtable
Dim file As DictionaryEntry
Dim errFrm As ErrorForm
Dim fileStr As String
If Not Me.Disposing Then
' create a hashtable of files and versions involved
For i = 0 To stack.FrameCount - 1
If Not files.ContainsKey(stack.GetFrame(i).GetMethod.DeclaringType.Assembly.Location) Then
files.Add(stack.GetFrame(i).GetMethod.DeclaringType.Assembly.Location, _
stack.GetFrame(i).GetMethod.DeclaringType.Assembly.GetName.Version.ToString)
End If
Next
For Each file In files
fileStr += file.Key & " - " & file.Value & vbCrLf
Next
errFrm = New ErrorForm
If Not t Is Nothing Then
errFrm.messageLbl.Text = t.Exception.Message
errFrm.stacktraceTxt.Text = t.Exception.ToString & vbCrLf
Else
errFrm.messageLbl.Text = "Invalid exception trapped by default handler"
errFrm.stacktraceTxt.Text = "Not available"
End If
If Not Me.IsDisposed Then
'Mailer.Send(t.Exception.ToString & vbCrLf & fileStr, "Computer name: " & System.Environment.MachineName & _
' vbCrLf & "User name: " & System.Environment.UserName & vbCrLf)
LogError(Strings.Left(t.Exception.ToString & vbCrLf & fileStr, 7000))
errFrm.filesTxt.Text = fileStr
errFrm.ShowDialog(Me)
errFrm.Dispose()
End If
stack = Nothing
End If
End Sub

I forgot to mention this. each time i hit the title to go to title detail screen. in console it throws this msg
The thread '<no name="">' (0x2378) has exited with code 0 (0x0) and it keeps building up for each event (i.e clicking the title to get to title detail screen) and at the end it crash. so below is the output of the debug msg.
The application crashed when i try to see the title detail in 16th time

Not sure what you mean by errorform constructor code. i believe this..
Public Class ErrorForm
Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New()
MyBase.New()
mLoadTime = Date.Now
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
.....

OK,
I think the problem you are having is caused by doing the ErrorForm stuff on a thread
that is not the main thread. When you do that on .NET 1.1 the app may hang, or the GUI
may fail to behave normally at any time; when you do that on .NET >= 2.0 you will get
an InvalidOperationException mentioning a "cross-thread-violation".
What you need to do is make sure the GUI-related code (that includes everything concerning
ErrorForm) to execute on the GUI thread; that is exactly the purpose of the
Control.InvokeRequired property and the Control.Invoke() method. I also would consider
creating the ErrorForm only once at app initialization, and populating and showing then
hiding it when appropriate (through Invoke).
As I said before, a more recent .NET version helps you in recognizing this kind of
faulty situation long before it causes trouble.

do you think is that why the memory is not freeing up? do you think this is whats causing the whole thing? each time i go from title to title detail it increases the memory by around 5mb and even when i go back it doesn't free the memory up.

I don't know about your memory situation; I do know any app that violates the "every control
should only be accessed by the thread that created it" rule will behave badly, it may
freeze the GUI, hang completely, or (for a while) seem to function normally; whatever the
symptoms, it can not be trusted.
If you violate the rule, first thing to do is fix it. Everything else that remains has
to be handled thereafter.

I'm not really sure about this but try looking in to using the event of KeyPress on you form.
in C# you'd get teh event with something like this.KeyPress+=new K...

I want to learn how to make an application like Shaderman in which we have blocks representing code and which we link together with lines. How are these block build? How are the lines being drawn? Did they use graphics 2d in C# to make the blocks and lines? Where could I find information?

Have you taken a look at what it's written in? Python - I figured that was mockery enough right there.

Hi friends
I have requirement like this.
Let's assume if one form contains more than one data grid which is used to populate different data's.
To identify the grid contents we can use grid caption.
Instead of using the grid caption show the Images in top left corner of data grid.
If any one come across this requirement.
Let me know how you were succeed this requirement
