The clickable area of the menu is still not enlarged by font. Is there any other way? The left and top of the client area of the form should also be adjusted according to the font size. How to do this?
vb setSystemMetrics,maybe need use for set menu area height?
Declare Function GetSystemMetrics& Lib "user32" (ByVal nIndex&)
Const SM_CYCAPTION = 4
Const SM_CYMENU = 15
or hook GetSystemMetrics(SM_CYMENU),return font height?
