Question

I have a Visual C++ forms application for Windows, using Visual Studio 2010. I want to fire off a thread under this event:

private: System::Void Form1_Shown(System::Object^  sender, System::EventArgs^  e) {

}

How can I do this? I have been searching for hours and it doesn’t seem to work for me 🙁 can someone show me how I need to set up a thread that runs another method, and how to set up that method, and everything else (declarations, namespaces you use, etc)?

If you want to explore Visual C++, you will probably be better off working with unmanaged C++, and creating your application using the Win32 API and MFC for the GUI. C++/CLI is a very powerful language, but it basically requires you to know both C++ and C# before you even get started.

That said, here’s how you do it:

using namespace System;
using namespace System::Threading;

static void MyThreadFunc()
{
   // Insert code to be run on the other thread here.
}

void Form1_Shown(Object^ sender, EventArgs^ e)
{
    Thread^ thread = gcnew Thread(gcnew ThreadStart(&ClassName::MyThreadFunc));
    // If MyThreadFunc is an instance method, use "gcnew ThreadStart(this, &ClassName::MyThreadFunc)" to get the delegate.
    thread->Start();
}
