Hello

for what we use the following
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long

Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long

Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long

Private Const WS_EX_LAYOUTRTL = &H400000

Private Const GWL_EXSTYLE = (-20)



with thanks

GetWindowLong and SetWindowLong is used to get/set attributes of windows, like WindowProcs, Styles, and others.

FindWindowEx is used to wind a subwindow within a window (eg. a textbox).

WS_EX_LAYOUTRTL is used for Right to Left Reading (no idea).

GWL_EXTSTYLE is used to return/set the extended style of a window (the ones that DOES NOT fit in one WindowLong), marked with a WS_EX_ instead of just a WS_.

Right-to-left is for languages like Hebrew where you read it from right to left, rather than left to right as you would in English.
