Thread: trying Ex and its not working

hi im messing with CreateWindowEx and some things but now my app wont show..heres the code

Code:

#include <windows.h>

LRESULT CALLBACK WndProc(HWND , UINT , WPARAM , LPARAM);

static char szAppName[] = "test";
HWND hwnd , button1 , button2;
MSG msg;
WNDCLASSEX wc;

int WINAPI WinMain(HINSTANCE hInstance , HINSTANCE hPrevInstance , PSTR szCmdLine , int iCmdShow)
{
	wc.style = CS_DBLCLKS;
	wc.lpfnWndProc = WndProc;
	wc.cbClsExtra = 0
	wc.cbWndExtra = 0;
	wc.hInstance = hInstance;
	wc.hIcon = LoadIcon(NULL , IDI_APPLICATION);
	wc.hCursor = LoadCursor(NULL , IDC_ARROW);
	wc.hbrBackground = CreateSolidBrush(GetSysColor(COLOR_3DFACE));
	wc.lpszMenuName = NULL;
	wc.lpszClassName = szAppName;

	if(!RegisterClassEx(&wc)) return 0;

	hwnd = CreateWindowEx(0 , szAppName , "test" ,
						WS_OVERLAPPEDWINDOW ,
						CW_USEDEFAULT , CW_USEDEFAULT ,
						CW_USEDEFAULT , CW_USEDEFAULT ,
						HWND_DESKTOP , NULL , hInstance , NULL);

	button1 = CreateWindow("button" , "test" ,
						WS_CHILD | WS_VISIBLE | BS_GROUPBOX ,
						50 , 50 ,
						200 , 100 ,
						hwnd ,
						NULL ,
						(HINSTANCE)GetWindowLong(hwnd , GWL_HINSTANCE) ,
						NULL);

	button2 = CreateWindowEx(WS_EX_WINDOWEDGE , "button" , "test" ,
							WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON ,
							75 , 75 ,
							120 , 20 ,
							hwnd ,
							NULL ,
							(HINSTANCE)GetWindowLong(hwnd , GWL_HINSTANCE) ,
							NULL);



	ShowWindow(hwnd , SW_SHOW);
	UpdateWindow(hwnd);

	while(GetMessage(&msg , NULL , 0 , 0))
		{
			TranslateMessage(&msg);
			DispatchMessage(&msg);
		}
		return msg.wParam;
}

LRESULT CALLBACK WndProc(HWND hwnd , UINT message , WPARAM wParam , LPARAM lParam)
{
	switch(message)
	{
		case WM_DESTROY:
			PostQuitMessage(0);
			return 0;

	}
	return DefWindowProc(hwnd , message , wParam , lParam);
}

the window doesnt show

Code:

#include <windows.h>

LRESULT CALLBACK WndProc(HWND , UINT , WPARAM , LPARAM);

static char szAppName[] = "test";


int WINAPI WinMain(HINSTANCE hInstance , HINSTANCE hPrevInstance , PSTR szCmdLine , int iCmdShow)
{

HWND hwnd , button1 , button2;
MSG msg;
WNDCLASSEX wc;

    wc.cbSize = sizeof(WNDCLASSEX);
	wc.style = CS_DBLCLKS;
	wc.lpfnWndProc = WndProc;
	wc.cbClsExtra = 0;
	wc.cbWndExtra = 0;
	wc.hInstance = hInstance;
	wc.hIcon = LoadIcon(NULL , IDI_APPLICATION);
	wc.hCursor = LoadCursor(NULL , IDC_ARROW);
	wc.hbrBackground = CreateSolidBrush(GetSysColor(COLOR_3DFACE));
	wc.lpszMenuName = NULL;
	wc.lpszClassName = szAppName;
    wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);

	if(!RegisterClassEx(&wc))
    {
    MessageBox(NULL,"class reg failed","doh!",MB_OK);
    return(1);
    }

	hwnd = CreateWindowEx(0 , szAppName , "test" ,
						WS_OVERLAPPEDWINDOW ,
						CW_USEDEFAULT , CW_USEDEFAULT ,
						CW_USEDEFAULT , CW_USEDEFAULT ,
						HWND_DESKTOP , NULL , hInstance , NULL);

	button1 = CreateWindow("button" , "test" ,
						WS_CHILD | WS_VISIBLE | BS_GROUPBOX ,
						50 , 50 ,
						200 , 100 ,
						hwnd ,
						NULL ,
						(HINSTANCE)GetWindowLong(hwnd , GWL_HINSTANCE) ,
						NULL);

	button2 = CreateWindowEx(WS_EX_WINDOWEDGE , "button" , "test" ,
							WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON ,
							75 , 75 ,
							120 , 20 ,
							hwnd ,
							NULL ,
							(HINSTANCE)GetWindowLong(hwnd , GWL_HINSTANCE) ,
							NULL);



	ShowWindow(hwnd , SW_SHOW);
	UpdateWindow(hwnd);

	while(GetMessage(&msg , NULL , 0 , 0))
		{
			TranslateMessage(&msg);
			DispatchMessage(&msg);
		}
		return msg.wParam;
}

LRESULT CALLBACK WndProc(HWND hwnd , UINT message , WPARAM wParam , LPARAM lParam)
{
	switch(message)
	{
		case WM_DESTROY:
			PostQuitMessage(0);
			return 0;

	}
	return DefWindowProc(hwnd , message , wParam , lParam);
}

changes made:
moved your MSG, HWND and WNDCLASSEX statemnts inside of minmain
added: wc.cbSize = sizeof(WNDCLASSEX);
added: wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
changed: your regclassex function to return if it worked, before the app just flunked.

w00t just solved someone's problem. a first for me here

hehe..thanks

would you happen to know how to take the doted lines out from the inside of a button when its clicked?

I don't know if you can completely disable focus rectangle, but you can set focus to your parent window after button has been clicked like so:

Code:

case WM_COMMAND:
  {
    WORD wNotifyCode = HIWORD(wParam);
    WORD wID         = LOWORD(wParam);
    if (lParam)
    {
      switch (wID)
      {
      case IDC_MYBUTTON:
        if (wNotifyCode == BN_CLICKED)
        {
          SetFocus(hWnd);
          // TODO: Add button code here
        }
        break;
      }
    }
  }
  return 0;

But you have to add control ID to your button like this (remember to #define IDC_MYBUTTON):

Code:

button2 = CreateWindowEx(WS_EX_WINDOWEDGE, "button", "test",
                         WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,
                         75, 75, 120, 20,
                         hwnd, (HMENU)IDC_MYBUTTON,
                         (HINSTANCE)GetWindowLong(hwnd, GWL_HINSTANCE), NULL);

If you don't like focus rectangle then you can allways use BS_OWNERDRAW syle of course...

hmmm..i was thinking there would be a way because MFC and ATL dont have it and there based on api
