Form Applications in Visual Studio and Threads

[kargo]

Hi,
I'm writting messenger in c++, but this VS10 is ........ing me off. I have a class which has function I run as thread :

cResult =  recv(this->_sock, Packet.buff, 1024, 0);
		if (cResult > 0)
		{
			Packet.size = cResult;
			Packet.from = (int*)this;

			switch (Packet.buff[2])
			{
				case 1: return this->IcomingPacket_AuthResult(Packet); break;
			}
		}

And now what I want to do is to display message in richBox on Form. How to call that stupid richBox within my class file let's say it "MyClass.cpp"??

Another thing is that boost thread isnt working when I use GUI :

Error	3	error C3861: '_InterlockedExchange': identifier not found	C:\c++ visual\boost_1_49_0\boost\smart_ptr\detail\spinlock_w32.hpp	62	1	Messenger_Client
Error	4	error C3861: '_InterlockedExchange': identifier not found	C:\c++ visual\boost_1_49_0\boost\thread\win32\basic_timed_mutex.hpp	46	1	Messenger_Client
Error	5	error C3861: '_InterlockedExchangeAdd': identifier not found	C:\c++ visual\boost_1_49_0\boost\thread\win32\basic_timed_mutex.hpp	160	1	Messenger_Client
Error	8	error C3861: '_InterlockedExchange': identifier not found	C:\c++ visual\boost_1_49_0\boost\smart_ptr\detail\spinlock_w32.hpp	62	1	Messenger_Client
Error	9	error C3861: '_InterlockedExchange': identifier not found	C:\c++ visual\boost_1_49_0\boost\thread\win32\basic_timed_mutex.hpp	46	1	Messenger_Client
Error	10	error C3861: '_InterlockedExchangeAdd': identifier not found	C:\c++ visual\boost_1_49_0\boost\thread\win32\basic_timed_mutex.hpp	160	1	Messenger_Client

Please help me asap

Just to make sure I understand, this is using C++ .NET with Windows Forms? And the problem you are having is that you cannot manipulate the GUI from a non-GUI thread?

You can use richBox.Invoke() to cause code to run on the GUI thread. See here: Control.Invoke Method (Delegate) (System.Windows.Forms)

The errors about missing InterlockedExchange functions are sometimes caused by not including windows.h, which could happen if boost is not properly configured, you're missing the Windows SDK, etc.

I dont even know how to change Text of richbox within the method of my class. This class is in another file and I have to call somehow to my form object. Tried this way but didnt work :/

Form1.richTextBox1->Text("Logged");

Honestly its my first gui in Visual, so far I wrote only console apps in c++ and gui in Delphi.
