Thread: Ws_popup

In a program i am working on i need a new window that pops up and has no border or title bar. I used a WS_POPUP style as it is perfect with no title bar, no boarder, just a plain window. But i need to allow the user to be able to move it around as with normal windows. however the WS_POPUP is static... So how do i go about creating this. i know its simple, i've just never done this, nor can i find any information on it.

I don't think there's a 'style' you can give a window to do this, however it's would be pretty easy to implement it. This will move a popup window (300x300) while the left mouse button is held down, and should give you some ideas -

Code:

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
	PAINTSTRUCT ps;
	HDC hdc;
	static POINT pWindowOrigin = {0,0};
	static POINT pMouseOrigin = {0,0};
	static POINT pMouseDestination = {0,0};
	static BOOL bWindowMoving=FALSE;


	switch (message) 
	{

	case WM_LBUTTONDOWN:
		bWindowMoving=TRUE;
		//Ensure mouse input isn't lost
		//if leaves client area
		SetCapture(hWnd);
		pMouseOrigin.x=LOWORD(lParam);
		pMouseOrigin.y=HIWORD(lParam);
	
		break;

	case WM_LBUTTONUP:
		bWindowMoving=0;
		ReleaseCapture();
		break;
	
	case WM_MOUSEMOVE:
		if(bWindowMoving)
		{
			pMouseDestination.x=LOWORD(lParam);
			pMouseDestination.y=HIWORD(lParam);
			int x= pMouseDestination.x-pMouseOrigin.x;
			int y= pMouseDestination.y-pMouseOrigin.y;
			pWindowOrigin.x+=x;
			pWindowOrigin.y+=y;
			MoveWindow(hWnd,pWindowOrigin.x,pWindowOrigin.y,
				300,300,TRUE);
			
		}break;
	


	case WM_PAINT:
		hdc = BeginPaint(hWnd, &ps);
		EndPaint(hWnd, &ps);
		break;
	
		
	case WM_DESTROY:
		PostQuitMessage(0);
		break;
	default:
		return DefWindowProc(hWnd, message, wParam, lParam);
	}
	return 0;
}

You could try using a dialog that pops up. You can create it without a boarder and titlebar. I have used the resource editor to do this before.
