EnumThreadWndProc Callback Function

Public Function EnumThreadWndProc (ByVal hwnd As Long, ByVal lParam As Long) As Long
  ' application-defined code goes here
End Function

Description & Usage

EnumThreadWndProc is an application-defined callback function used by EnumThreadWindows for each window enumerated. This function should process the window in whatever manner is required. This function does not necessarily have to be named EnumThreadWndProc -- that is merely the name given to it in discussions about the API.

Return Value

If the function returns 0, EnumThreadWindows will immediately stop enumerating thread windows. If the function returns a non-zero value, EnumThreadWindows will continue enumerating thread windows until it can no longer find any.

Visual Basic-Specific Issues

Like all callback functions, EnumThreadWndProc must be declared Public and be defined in a module.

Parameters

hwnd

A handle to the window which EnumThreadWindows has just found.

lParam

Whatever value was specified in the parameter list of EnumThreadWindows.
