Problem in retrieving text using WM_GETTEXT

[Javagal Srinath]

Hi I was using sendmesage function to a window in my DLL which is attached to other application using windows hook, mainly to get text from a control. sendmessage(hwnd,WM_GETTEXT,(wparam)100,(lparam)sztext); To my surprise sendmessage was not able to retrieve text in sztext. could the problem lies in the creator of application who has not properly written code in WM_GETTEXT case. I think he/she may not have written appropriate code to provide proper response when send message function with WM_GETTEXT is called. Am I wrong in analysing please reply if u have encountered a problem like this before thanks

It's hard to say. Here[^] is an interesting article on WM_GETTEXT and GetWindowText. Steve

Was it a password edit box ? ~RaGE();

Is hwnd a valid window handle?

How was sztext declared?

No offense meant, it is only that edit boxes with password option set react differently to the WM_GETTEXT message as when it is not set. ~RaGE();

hwnd was a window handle returned when a notification that a new window is created was recieved to my filter function cbtproc. The hook code was HCBT_CREATEWND I think sztext was properly declared May be we can not send "sendmessage(hwnd,WM_GETTEXT,(wparam)100,(lparam)sztext);" to retrieve text to all type of window.
