How to create Dialogs and Windows in the center of the Screen? (Visual C++)
I know how to make em, just not how to make them centered, since I've no clue about how to get the screensize, not even a fucntion name, I'll just ask it here.

I am NOT using MFC, just the regular win32API calls

I do have a WM_INITDIALOG, ill try put your centerwindow there
Well, following on from AAB's suggestion, I would say that you need a handle to your window, and the API calls GetParent, GetClientRect and SetWindowPos (in that order). A hint on how to implement it: look at the source code for CWindow::CenterWindow() (in ATLWIN.h, line 1134 in my version)

The problem is not the window, really, more is getting the screens resolution so that I can center it ;)

>>getting the screens resolution so that I can center it
You *can* center it using only the code in ATLWIN.h as mentioned above. Did you look at the lines
// center within screen coordinates
::SystemParametersInfo(SPI

I'll try these and award the right one - srry I';ve been offline so long.
void CenterWindow( CWnd* pAlternateOwner = NULL );
Parameters
pAlternateOwner
Pointer to an alternate window relative to which it will be centered (other than the parent window).
Centers a window relative to its parent. Usually called from CDialog::OnInitDialog to center dialog boxes relative to the main window of the application. By default, the function centers child windows relative to their parent window, and pop-up windows relative to their owner. If the pop-up window is not owned, it is centered relative to the screen. To center a window relative to a specific window which is not the owner or parent, the pAlternateOwner parameter may be set to a valid window. To force centering relative to the screen, pass the value returned by CWnd::GetDesktopWindow as pAlternateOwner.
Example
BOOL CAboutDlg::OnInitDialog()
{
CDialog::OnInitDialog();
CenterWindow();
return TRUE;
}
