Question

i have a function

void __stdcall TestThread( String^ a, String^ b)
{
 MessageBox::Show( a );
 MessageBox::Show( b );

 _endthread();
}

And i want to create a thread like this:
_beginthread( &HWSW_GUI::Form1::TestThread , 0, NULL );

Unfortunately i’m getting an error:
Error 2 error C3374: can't take address of 'HWSW_GUI::Form1::TestThread' unless creating delegate instance d:\testvs2008\hwsw_gui\hwsw_gui\Form1.h 5177

Can someone help me please? It is driving me crazy, and i can’t it figure it out.

Thanks!

Use managed thread instead of _beginthread.

To pass parameter to the thread, use Thread(ParameterizedThreadStart) constructor: http://msdn.microsoft.com/en-us/library/1h2f2459.aspx

Generally, working with any .NET language, including C++/CLI, avoid using unmanaged stuff (like PInvoke or mixing managed/unmanaged code in C++/CLI), unless this is absolutely necessary. Most standard programming tasks may be solved using pure managed code.
