Hi,
I have the folloving code:
Public class MyForm : Form
{
……
void SomeMethod()
{
a = new Obj1(this);
Thread t = new Thread( new ThreadStart( a.CallMethod ) );
t.Start();
}
}
Class Obj1
{
Public Obj1(Form myForm)
{
parent = myForm;
}
Public void CallMethod()
{
…
if (parent != null) //// so far debugging is OK
{
Do something
}
Process.Start(. ..) //Run a process (external exe file)
....
if (parent != null) //// =Debugger will hang
{
Do something
}
}
The debugger will either hang out on the second occurence of "if (parent !=
null)" or sometimes it seems like it goes through but doesn't stop on any
futher break point. When I run it wthout a debugger, everything is OK.
I am debugging form a Vista 64 bit machine, and application (32 bits) is
running on virtual machine VMWare, Vista 32. I am attaching debugger to the
process while debugging.
Why I can not debugging it?
Thanks,
Lubomir 3 1342

I think when you try to access the form from a different thread , it
does not like it...
try this
MyForm .CheckForIllega lCrossThreadCal ls=false;
to see if that is the probelm..

It is the same even when I pass null instead of "this".
Could you provide details of the process start call. Are you redirecting
output or anthing that will stop the process finishing. Maybe that is the
cause of the hang

I'm using Visual Studio 2005 Pro final, and I've noticed some bizarre
behaviour when I'm debugging programs with multiple threads.
Specifically, if I set a breakpoint in one of my non-UI threads, and
try to step-over a line of code, my thread aborts and pretty much
breaks my application. I tried a similar test in a console application
and it seems to work fine.
Here is a sample to show what I mean. Create a new Windows application...

Alright, based a on discussion on this mailing list, I've started to
wonder, why use threads vs processes. So, If I have a system that has a
large area of shared memory, which would be better? I've been leaning
towards threads, I'm going to say why.
Processes seem fairly expensive from my research so far. Each fork
copies the entire contents of memory into the new process. There's also
a more expensive context switch between...

While debugging my application I have noticed that occasionally a message
saying "Win32 Thread xxxx exited with code 0 (0x0)" appearing in the debug

I found that the threads were only there in programs that used...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
