   The program I wrote monitors all windows running at a users   
   workstation, frequently testing those windows for text boxes, list   
   boxes, etc. for a specific string of characters that might contain   
   names of clients.  Any number of programs might be run at the user's   
   workstation that might contain such info.  If that string is found, my   
   program reacts by searching our own databases, documents, etc. for all   
   info pertaining to that client as an alert to the user of specific   
   procedures that must not be missed should they forget to check   
   themselves.   
      
   It works, but using the windows handle for each window found by   
   enumerating through the windows using EnumWindowProc() and   
   EnumChildProc() I still need to loop through each of those windows to   
   find the ID of the text boxes, etc. using the following code which   
   will find the text I'm searching in the variable strWindowsText below:   
      
   For lngCtrlId = 1 to 100   
       lngCtrlHWND = GetDlgItem(hWnd, lngCtrlId)   
       strWindowText = String(80, Chr(0))   
       SendMessage lngCtrlHWND, WM_GETTEXT, 100, ByVal strWindowText   
   Next lngCtrlId   
      
   As an example, if you open Notepad and type "Test" in Notepad's edit   
   screen, my program will find the string "Text" since I already know   
   that the ID of Notepad's edit screen is 15.  But if I didn't know the   
   ID is 15, I would need to loop through all possible values until I   
   reached 15 and my program would then find the text.  But an ID can be   
   as high as the maximum number for the ID data type, and to run a loop   
   to such a high number for all windows running may cause enough of a   
   delay to be ineffective.   
      
   I've already tried using GetDlgID() as you and others suggested, but   
   using the Notepad example, it doesn't seem to return a value of 15 as   
   the ID for the Notepad edit screen.   
      
   I'm going on the assumption I'm missing something here so I still plan   
   to play around with these suggestions.  Maybe I'm just not using these   
   functions properly or perhaps the method I've been using is the only   
   way?   
      
   Ideally, I would like to get a list of all control IDs from all   
   windows and then use the ID and the hwnd values to grab the text from   
   each using SendMessage.
