Returns whether a window is the popup calculator window or one of its child windows.
C
BOOL SftMaskCalculatorWindow_IsCalculatorWindowOrChildWindow(HWND hwnd);
hwnd
The window handle to test.
Because the popup calculator is a separate top-level window, an application implementing focus- or activation-sensitive logic (e.g., closing its own popups when the "application" loses activation) can use this function to recognize the calculator as belonging to the masked edit control.
