Overview
The FindWindow function is a low-level function that locates a system wide window within a specified scope and returns the handle to that window.
Syntax/Parameters
Syntax
handle = FindWindow ( string class, [string title], [handle parent], [handle child] );
Parameters
class
A string specifying the class name of the window to find.
title
An optional string specifying the title of the window to match.
parent
An optional handle of the parent window to constrain the search. If the parameter is omitted or specified as NULL_HANDLE, the desktop is used, thus search all windows on the desktop.
child
An optional handle specifying the starting child window to start the search. The search begins with the next child window in the window Z-order.
Return Value
Returns a handle to the application frame window or NULL_HANDLE (0) if the window is not open. The handle should not be closed.
Remarks
The FindWindow function supports locating windows within the desktop tree of the current user. To find an edit window, use the FindEditWindow function.
The title is matched against the window text or caption for the window. The window text can also be the content or other data of the window depending on the class of window. It is generally set with the SetWindowText function, via resources of a number of other methods.
When specifying a child window parameter, the window must be a direct child window of parent window (not just a descendant of the parent window). If child is NULL_HANDLE or omitted, the search begins with the first child window of parent window. If both parent and child parameters are NULL_HANDLE or omitted, the function searches all top-level and message-only windows.
