hWnd ActiveX

Do you know hWnd? It's the handle of a window. In Windows system, the handle identifies every window and it's unique for every window. Some ActiveX need the hWnd of your form, button or picture box to operate the window. But some containers don't provide the property to get the handle of the window. Now with the FREE hWnd ActiveX, you can do that very easily. hWnd ActiveX is a 32bit OLE Control Module to help you to get the handle of the windows. You can get the parent, child, previous, next window's handle and you can search the window's handle by the caption text.

How to use hWnd ActiveX:
hWnd ActiveX has five methods to help you to get the window's handle.
GetParent(hWindow) : This method will return the parent window's handle of the hWindow.
GetChild(hWindow) : This method will return the first child window's handle of the hWindow.
GetNext(hWindow) : This method will return the sibling window below the hWindow.
GetPrevious(hWindow) : This method will return the sibling window above the hWindow.
FindWindow(hParentWindow, hChildAfter, Caption) : This method will search the window which caption is the same as Caption. The searching starts from the hParentWindow as the root window and begins with the next child window after hChildAfter. You can pass the returned value to hChildAfter in the next call to FindWindow to find all the windows whose captions are Caption.
hWindow, hParentWindow or hChildAfter are known window's handle which you can get from previous calls to hWnd ActiveX or the hWnd property of the hWnd ActiveX. If the method returns 0(zero), that means a error or no window.
hWnd property : The window's handle of hWnd ActiveX. You can pass this value to the methods of hWnd ActiveX.
hWnd ActiveX has its own window. If some containers, you still can get the hWnd from hWnd ActiveX if the ActiveX is invisible. But some containers not. In these containers, you need to set the hWnd ActiveX visible. If you don't want the users to see the ActiveX, you can put the ActiveX outside of the container window (for example, set Left and Top to -100, -100).
