"?" button on dialog box

[Deepak Dureja]

Hi,
How can I get the message that "?" button on dialog title has been clicked and I do whatever I want. I don't want to use it as context sensitive help. I want to display window when user clicks the "?" button.
Thanx in advance
Deepak

Hi,

I'm not surprised you had trouble with this as it seems completely undocumented (at least in my version of MS Dev), but with the help of Spy++ I discovered that this button actually sends a WM_SYS_COMMAND message with the id SC_CONTEXTHELP which you can intercept in the usual way!

Cheers,
Simon.
