EnumChildProc Callback Function

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

Description & Usage

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

Return Value

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

Visual Basic-Specific Issues

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

Parameters

hwnd

A handle to the window which EnumChildWindows has just found.

lParam

Whatever value was specified in the parameter list of EnumChildWindows.
