    Initializing My Control

    I am having problems linking to Comctl32.dll used for the common control API. How do I go about importing the information from the file?

    Did you link to the lib file?
    Also to ensure that the compiler links the lib file you should call InitCommonControls or InitCommonControlsEx

    I am using InitCommonControlsEx. I am unsure how to link to the lib file. That is the problem I'm having.

    You can do it with this
    Code:
    #pragma comment(lib,"COMCTL32.LIB").
    or if your using devc++ I think the library is named COMCTL32.A

    It still does not recognize my common control functions. What am I doing wrong?
    Code:
    // Example Shows How To Create A Basic Animation Control
    #include <windows.h>
    
    #pragma comment(lib,"COMCTL32.LIB")
    
    #define WIDTH 500
    #define HEIGHT 350
    
    void CreateMyWindow();
    LRESULT CALLBACK WndProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam);
    void CreateMyAnimation();
    void InitializeMyCommonControls();
    
    char szClassName[ ] = "Animation";
    
    HWND hWnd;
    HINSTANCE hInstance;
    HWND hWndAnim;
    
    // Main Window Procedure
    int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, 
    				   LPSTR iCmdLine, int iCmdShow)
    {
    	CreateMyWindow();
    	ShowWindow(hWnd, iCmdShow);
    
    	MSG Msg;
    	while (GetMessage (&Msg, NULL, 0, 0))
        {
            TranslateMessage(&Msg);
            DispatchMessage(&Msg);
        }
    }
    
    // Message Queue Procedure
    LRESULT CALLBACK WndProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)
    {
    	switch(Msg)
    	{
    		case WM_CREATE:
    			InitializeMyCommonControls();
    			CreateMyAnimation();
    			break;
    		case WM_DESTROY:
    			PostQuitMessage(0);
    			break;
    		default:
    			return DefWindowProc(hWnd, Msg, wParam, lParam);
    	}
    
    	return 0;
    }
    
    // Animation Control Creation Procedure
    void CreateMyAnimation()
    {
    	hWndAnim = Animate_Create(hWnd, 1, WS_BORDER | WS_CHILD, hInstance);
    }
    
    // Initialization of Common Controls Procedure
    void InitializeMyCommonControls()
    {
    	LPINITCOMMONCONTROLSEX lpInitCommonControlsEx;
    
    	lpInitCommonControlsEx.dwSize = (LPINITCOMMONCONTROLSEX);
    	lpInitCommonControlsEx.dwICC = ICC_ANIMATE_CLASS;
    
    	InitCommonControlsEx(lpInitCommonControlsEx);
    }
    
    // Window Creation Procedure
    void CreateMyWindow()
    {
    	WNDCLASSEX wndClassEx;
    
    	wndClassEx.cbSize = sizeof(WNDCLASSEX);
    	wndClassEx.style = CS_HREDRAW | CS_VREDRAW;
    	wndClassEx.lpfnWndProc = WndProc;
    	wndClassEx.cbClsExtra = 0;
    	wndClassEx.cbWndExtra = 0;
    	wndClassEx.hInstance = hInstance;
    	wndClassEx.hIcon = LoadIcon(NULL, IDI_WINLOGO);
    	wndClassEx.hCursor = LoadCursor(NULL, IDC_ARROW);
    	wndClassEx.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
    	wndClassEx.lpszMenuName = 0;
    	wndClassEx.lpszClassName = szClassName;
    	wndClassEx.hIconSm = LoadIcon(NULL, IDI_WINLOGO);
    
    	RegisterClassEx(&wndClassEx);
    
    	hWnd = CreateWindowEx(0, szClassName, "Animation Control", WS_OVERLAPPEDWINDOW,
    						  CW_USEDEFAULT, CW_USEDEFAULT, WIDTH, HEIGHT, 0, 0, hInstance, 0);
    
    }

    You also need to include the header file.
    Code:
    #include <COMMCTRL.H>
