If you're using keyboard hook (i.e., WH_KEYBOARD), you may use nonzero value as a result to block it. Here's a quote from MSDN:<br />
&quot;If the hook procedure processed the message, it may return a nonzero value to prevent the system from passing the message to the rest of the hook chain or the target window procedure.&quot;

Hi experts!<br />
I have a dokument with selected text. With my app I want to copy this text to path 'C:\A' &nbsp;by pressing 'a' or 'A'<br />
and/or to path 'D:\B' by pressing key 'B'. Hooking is not the problem, but how can I avoid to replace the selected<br />
text with my keystroke ?<br />
<br />
