    Question Problem with BN_CLICKED!! HELP!!

    Ok, I want to put the BN_CLICKED in an 'if' statement(to check if it was clicked). When I run it though, I get a popup that is supposed to popup only when the button is clicked. Help with the below code please!:

    case WM_CREATE:
    case WM_COMMAND:
    HWND btn;

    btn = CreateWindow(
    "button",
    "Click me",
    WS_CHILD | WS_BORDER | WS_VISIBLE,
    10,
    10,
    50,
    50,
    hwnd,
    (HMENU) 1,
    g_hInst,
    NULL
    );

    if((hwnd, (WPARAM)WM_COMMAND, (LPARAM)BN_CLICKED, btn) != 0)
    {
    MessageBox(hwnd, "Hello", "Greetings", MB_OK + MB_SYSTEMMODAL);
    }
    break;
    break;

    Post Didn't work..

    When I use case WM_COMMAND:
    switch(LOWORD(wParam))

    The button won't even show up.

    hey sorry it took me so long to reply, i have been really buisy

    i suspect that it didnt work because you are not breaking the case before your "paint" or "create" case's . anyway here is a WndProc that will show a button and display a msgbox when it is clicked.

    *****************************
    //make these global
    #define ID_CONNBUT 10
    HWND ConnBut;

    LRESULT CALLBACK WndProc(HWND hWnd,UINT messg, WPARAM wParam,LPARAM lParam)
    {

    HDC hdc ;
    HINSTANCE hInstance ;
    int x, y ;
    PAINTSTRUCT ps ;

    switch (messg)
    {

    case WM_CREATE:

    ConnBut = CreateWindowEx(WS_EX_STATICEDGE, "Button","Connect",WS_CHILD | WS_VISIBLE | WS_BORDER | ES_LEFT, 0,0,100,25, hWnd, (HMENU)ID_CONNBUT,g_hInst, 0);//connbut


    break;

    case WM_PAINT:
    hdc = BeginPaint (hWnd, &ps) ;


    EndPaint (hWnd, &ps) ;

    break;


    case WM_DESTROY:
    PostQuitMessage(0);
    break;

    case WM_COMMAND:
    switch (LOWORD (wParam))
    {
    case ID_CONNBUT:
    MessageBox(NULL,"TEXT","TITLE",NULL);
    break;
    }


    default:
    return(DefWindowProc(hWnd,messg,wParam,lParam));
    break;
    }

    return(0);

    }

    Try

    //*******************************
    case WM_COMMAND:

    idControl=GET_WM_COMMAND_ID(wParam,lParam) ;
    switch(idControl)
    {
    //*******************************
    //*******************************
    case IDC_SIDE:
    if(HIWORD(wParam)==BN_CLICKED)
    {
