I did not write this application but I need to run a separate application based on the information entered in the text captured. I am not too sure where to start looking as to how this could be accomplished. I have looked into system hooks but this would mean that my application would have to be running already and have captured the text while it was entered. Is there a way to 'read' a screen from another running application?

You should ask your question in the nativeapi newsgroup instead, as you will have to use the Windows API to accomplish what you are asking for. You need to find and obtain the HWND handle of the specific edit field you are interested in, and then you can query its current text.

I should have mentioned that I was looking for a component to perform the capture. But thank you for the information.

I have about 5 fields that I would like to capture and use to call my application. I think what I am looking for is what some people call 'screen scraping' but in a windows environment. I would like to call up my application which would 'scrape' the window in the other application and then provide me the information that I need to continue with my application.

Quote: I have about 5 fields that I would like to capture and use to call my application. I think what I am looking for is what some people call 'screen scraping' but in a windows environment. Screen scraping essentially takes a screenshot of the screen and then analyzes it for information. In most cases, multiple screenshots are taken and then compared to see what changed from one to the next (such as for creating animations using differential info to minimize the amount of data that has to be stored/transmitted). That is way outside the realm of what you are asking for. Like I told you earlier, all you need to do is find the HWND handle of the particular edit field that you are interested in, and then query its current value directly. There are plenty of ways to do that.

Quote: Sorry. I should have mentioned that I was looking for a component to perform the capture. You don't need a component for it. Just use the API directly, specifically FndWindow/Ex(), EnumChildWindows(), GetWindowText(), etc. And use tools such as Microsoft's Spy++ or Borland's WinSight to see the Parent/Child relationship between nested controls so you can figure out how deep to drill into a window to find the edit control you want.

I found some sample code that should get me started. If I have any more questions, I will continue in the nativeapi.win32 group Thanks again.
