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 have an answer for you, sorry, but i sure would be interested in knowing this too.

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.
