 Posted: Mon Mar 03, 2008 6:44 pm Post subject: [Solved]Calling thread from DLL |
 |
|
So basically I have a thread in my dll and a checkbox in my C# gui. I want it to call the thread from the dll when the checkbox is checked.
Something like this:
| Code: | if (mycheckbox.Checked == true)
{
//this is in C++: CreateThread(0, 0, (LPTHREAD_START_ROUTINE)&ThreadNAME, 0, 0, 0);
} |
Would I be able to do that? And if I use DllImport for my dll, would there be no parameters?

That woudnt work.
If you made a sepearte dll in C++ then u would DllImport it first, get the function that u wanna use.
then do
| Code: | if ( myCheckBox.Checked == true )
{
CallMyFunction(); // function name that u imported.
} |
and in your C++ Dll
| Code: | void __declspec(dllexport) CallMyFunction()
{
hTheadHandle = CreateThread( 0, 0, (LPTHREAD_START_ROUTINE)&ThreadNameInCDll, 0, 0, 0 );
} |

He Said that he's Calling it from a C# GUI, and he wants to call the function to create the thread within his dll.
C# doesnt even have CreateThread unless you Import it.

Bullshit.
Thread t = new Thread(new ThreadStart(VoidMethod_NoParamsHere));
t.Start();

Thread t = new Thread(new ThreadStart(VoidMethod_NoParamsHere));
t.Start(); |
I meant The API Function, not the C# Threading.

Oh, my bad.
Seemed like you were saying that you couldn't create threads in C# (which I disproved above).
