    CFileDialog Assertion Error

    Hello all, I am writing a program that is using a modeless dialog for the gui. MFC is used as a shared dll and when i create a CFileDialog I get a Debug Assertion Error, can anyone help me? Here is the Code:

    Code:
    case ID_LOADPROXIES:
    	{
    		CFileDialog dlg(TRUE,"*.txt",NULL,OFN_EXPLORER|OFN_FILEMUSTEXIST,"Txt files (*.txt)|*.txt|");
    			if(dlg.DoModal() == IDOK){
    				std::string s;
    					s.append(dlg.GetFolderPath());
    				s.append(dlg.GetFileName());
    					MessageBox(NULL, NULL, s.c_str(), MB_OK);
    			}
    	}
    break;
    As soon as the button is pressed the error happens, Any ideas?
