In this example the dialog box is placed above all open windows.
The main window of VFP is unavailable for input while the dialog exists. But all other open windows are accessible, though the dialog window keeps staying on the top.
After closing the dialog, the VFP main window may not acquire a focus automatically, depending on both OS and VFP versions in use.
Notice that HWND value used in this example is zero. That means that the dialog has no parent window. You can find HWND of the VFP Main window through the GetActiveWindow, or GetFocus (conditionally) functions.
A HWND passed to this function as a parameter -- I guess -- implies that you can take this value from any other window.
