Hello,
I have a C# project with windows forms.
I sometimes get unprdictable .NET exceptions. I don't always get them, so I
can't reproduce where exactly it happens. I can generally say it happens when
closing the application (maybe in the dispose method?).
Here are 2 examples:
System.Threadin g.ThreadAbortEx ception: Thread was being aborted.
at System.Windows. Forms.UnsafeNat iveMethods.Call WindowProc(IntP tr
wndProc, IntPtr hWnd, Int32 msg, IntPtr wParam, IntPtr lParam)
at System.Windows. Forms.NativeWin dow.DefWndProc( Message& m)
at System.Windows. Forms.Form.DefW ndProc(Message& m)
at System.Windows. Forms.Control.W ndProc(Message& m)
at System.Windows. Forms.Scrollabl eControl.WndPro c(Message& m)
at System.Windows. Forms.Container Control.WndProc (Message& m)
at System.Windows. Forms.Form.WndP roc(Message& m)
at System.Windows. Forms.Control.C ontrolNativeWin dow.OnMessage(M essage& m)
at System.Windows. Forms.Control.C ontrolNativeWin dow.WndProc(Mes sage& m)
at System.Windows. Forms.NativeWin dow.Callback(In tPtr hWnd, Int32 msg,
IntPtr wparam, IntPtr lparam)
System.Threadin g.ThreadAbortEx ception: Thread was being aborted.
at System.Windows. Forms.UnsafeNat iveMethods.SetF ocus(HandleRef hWnd)
at System.Windows. Forms.Container Control.FocusAc tiveControlInte rnal()
at System.Windows. Forms.Form.set_ Active(Boolean value)
at System.Windows. Forms.Form.WmAc tivate(Message& m)
at System.Windows. Forms.Form.WndP roc(Message& m)
at System.Windows. Forms.Control.C ontrolNativeWin dow.OnMessage(M essage& m)
at System.Windows. Forms.Control.C ontrolNativeWin dow.WndProc(Mes sage& m)
at System.Windows. Forms.NativeWin dow.Callback(In tPtr hWnd, Int32 msg,
IntPtr wparam, IntPtr lparam)
Any ideas?
thanks,

When checking the code more thoroughly It looks something like this:
void Main {
int retval = foo();
if (retval == FAILED) {
System.Environm ent.Exit(-1); }
else {
System.Windows. Forms.Applicati on.Run(new psScheduleTasks ()); }
}
void foo {
Thread a;
a = new Thread(new ThreadStart(Sho wWaitScreen));
a.Start();
more code...
a.abort();
return retval;
}
The exception is thrown when foo returns FAILED.
I tried using System.Windows. Forms.Applicati on.Exit() instead of
System.Environm ent.Exit(-1), but the exception is still begin thrown.

Are you spawning threads in your app?
Sometimes it happens when you close an application and some threads
are still running.

Hi,
I'm experiencing a wierd problem with IE 6 in Windows with two
_slightly_ different Version.
Give the following HTMl-Code, ideally the output of offsetTop should be
"105"; a few pixel plus minus would still be ok, whyever.
I've tested this successfully on 6.0.2800.1106 on a german W2KPro
machine, also with 6.0.2800.1106 on a german XPPro machine.

This is very strange: I have a Windows Form with a Panel on it. In that
panel I dynamically (at run time) create some labels, as so:
for i=1 to x
dim ctlNew as New Label()
with ctlNew
.Name="Whatever" & trim(cstr(i))
.Text=.Name
.Visible=True

This is driving me crazy and I really hope I can get an answer...
Take a look at the piece of code below (I'm using .net 2.0):

double pointTime = XDate.DateTimeToXLDate(point.time);
double pointValue = Convert.ToDouble(point.value);
list.Add(pointTime, pointValue);

In my web.config I added <pages enableSessionState="true">.
In each of my pages I also added EnableSessionState="True" to the Page

Any reason why even though I did this I keep getting this error....
