Posted: Tue Nov 11, 2008 7:37 pm Post subject: [C++] Icon in a DLL GUI

Code:

void Window()
{
HWND hWnd;
MSG iMsg;
WNDCLASSEX wc;

ZeroMemory(&wc,sizeof(WNDCLASSEX));

wc.cbSize = sizeof(WNDCLASSEX);
wc.style = CS_HREDRAW | CS_VREDRAW;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hbrBackground = (HBRUSH)COLOR_BTNHIGHLIGHT;
wc.hIcon = LoadIcon(NULL,IDI_APPLICATION);
wc.hCursor = LoadCursor(NULL,IDC_ARROW);
wc.hInstance = Module;
wc.lpfnWndProc = WndProc;
wc.lpszMenuName = NULL;
wc.lpszClassName = _T("Wintermute");
wc.hIconSm = LoadIcon(NULL,IDI_APPLICATION);

if (!RegisterClassEx(&wc)){
   MessageBox(0,_T("Failed"),0,0);
   ExitWindow();
}
hWnd = CreateWindowEx(WS_EX_APPWINDOW | WS_EX_DLGMODALFRAME,_T("Wintermute"),_T("GrandChase Trainer"),WS_SYSMENU,CW_USEDEFAULT,CW_USEDEFAULT,200,130,0,0,Module,0);
ShowWindow(hWnd,SW_SHOWNORMAL);
UpdateWindow(hWnd);

while (GetMessage(&iMsg,0,0,0))
{
   TranslateMessage(&iMsg);
   DispatchMessage(&iMsg);
}
ExitWindow();
}

Basically, I have an icon added as a resource. This icon is called Icon_1.ico. My problem is that I have no clue how to do it. I have tried changing wc.hIcon and wc.hIconSm but, it doesn't change anything...

The GUI otherwise works...

wc.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDC_ICON1); * - Italics: Change them to your identifiers that hold the instance and resource ID. _________________

Code:

#define IDI_ICON1 L"GC_Icon.ico"
...
HMODULE Module;
...
void Window()
{
HWND hWnd;
MSG iMsg;
WNDCLASSEX wc;

ZeroMemory(&wc,sizeof(WNDCLASSEX));

wc.hInstance = Module;
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = CS_HREDRAW | CS_VREDRAW;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hbrBackground = (HBRUSH)COLOR_BTNHIGHLIGHT;
wc.hIcon = LoadIcon(Module,IDI_ICON1);
wc.hCursor = LoadCursor(NULL,IDC_ARROW);
wc.lpfnWndProc = WndProc;
wc.lpszMenuName = NULL;
wc.lpszClassName = _T("Wintermute");
wc.hIconSm = LoadIcon(Module,IDI_ICON1);//LoadIcon(NULL,IDI_APPLICATION);

if (!RegisterClassEx(&wc)){
   MessageBox(0,_T("Failed"),0,0);
   ExitWindow();
}
hWnd = CreateWindowEx(WS_EX_APPWINDOW | WS_EX_DLGMODALFRAME,_T("Wintermute"),_T("GrandChase Trainer"),WS_SYSMENU,CW_USEDEFAULT,CW_USEDEFAULT,200,130,0,0,Module,0);
ShowWindow(hWnd,SW_SHOWNORMAL);
UpdateWindow(hWnd);

while (GetMessage(&iMsg,0,0,0))
{
   TranslateMessage(&iMsg);
   DispatchMessage(&iMsg);
}
ExitWindow();
}
...
BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
if (ul_reason_for_call == DLL_PROCESS_ATTACH)
{
   Module = hModule;
   CreateThread(0,0,(LPTHREAD_START_ROUTINE)&Window,0,0,0);
}
return TRUE;
}

For some reason, this does not work. To add the icon, I right-clicked the project Add->Existing->GC_Icon.ico

I am still rather new to CreateWindow and all that but, basically, once this icon is added, the trainer is finished so, I would love you for numerous years if you could tell me where I am screwing...

Take out WS_EX_DLGMODALFRAME from the dwExStyle and the icon will come up _________________
