VS 2005 / C++ / __gc program (converted from VS 2003)
i have this code in my program:
int found;
String *temp;
this->ofdOpen->ShowDialog() ;
the last line produces the folloing unhandleld exeption:
An unhandled exception of type 'System.Threadi ng.ThreadStateE xception'
occurred in System.Windows. Forms.dll
Additional information: Current thread must be set to single thread
apartment (STA) mode before OLE calls can be made. Ensure that your Main
function has STAThreadAttrib ute marked on it. This exception is only raised
if a debugger is attached to the process.
However my Main funtion lookes like this:
int APIENTRY _tWinMain(HINST ANCE hInstance, HINSTANCE hPrevInstance, LPTSTR
lpCmdLine, int nCmdShow)
{
System::Threadi ng::Thread::Cur rentThread->ApartmentSta te =
System::Threadi ng::ApartmentSt ate::STA;
Application::Ru n(new fclMain());
return 0;
}
Can anybody explain to me whats wrong? 3 7773

Was the call to ofdOpen->ShowDialog from your main thread, or from another?
-cd
System::Threadi ng::Thread::Cur rentThread->ApartmentSta te =
System::Threadi ng::ApartmentSt ate::STA;
makes no sense here, it's too late to set the ApartmentState at this point,
note also that _tWinMain is also not the real entry point of this 'WinForms'
application, so it makes no sense either to set the STAThreadAttrib ute as
suggested by the error message.
All you can do is set the /CLRTHREADATTRIB UTE:STA linker switch.

I just realized that the entire structure of code is different when you
convert a VS 2003 solution to VS 2005 compared to starting a new project in
VS 2005. VERY frustrating. I decided to start the project over in VS 2005.
Thanks anyway.
