GetDialogDpiChangeBehavior function

Returns the flags that might have been set on a given dialog by an earlier call to SetDialogDpiChangeBehavior.

If that function was never called on the dialog, the return value will be zero.

Syntax


DIALOG_DPI_CHANGE_BEHAVIORS WINAPI GetDialogDpiChangeBehavior(
   HWDN hDlg
);

Parameters

hDlg

The handle for the dialog to examine.

Return value

The flags set on the given dialog. If passed an invalid handle, this function will return zero, and set its last error to ERROR_INVALID_HANDLE.

Remarks

It can be difficult to distinguish between a return value of DDC_DEFAULT and the error case, which is zero. To determine between the two, it is recommended that you call GetLastError() to check the error.
