I am not sure if this is possible but I need to know when a window is about to close and before it closes, retrieve some information from the window.
For example, if Notepad is running and you click the X to close it, can a DLL know this and get information such as the window caption and also let me call an API to retrieve the text first?
I also want to do this child windows such as an instant message in AOL. When the IM window is about to be closed, perform some action with an API call first.
My problem working with hooks is some of them hang. So I don't want this DLL to hang the system at all and it must work with Windows 98,ME,XP and NT.
Please let me know if you can do this and also if you can have it work with child windows as well. Do child windows within other programs such as AOL send notifications to windows? I would imagine.
ONLY BID if you know exactly how to do this and can do it asap. I need this very soon. If you have an example of this routine already done, then I could accept your bid sooner. I need to call this DLL from my VB 6.0 program to turn it on and off and to be notified with the information I need when any window closes. So a sample VB app would be needed with it to show how to use it.
