changing dialog box property at runtime

[rahul]

I want to Launch a Dialog box from my mfc application.

Dialog Box is launched through a exported function from .dll

I want to keep Context Help Button (at top-right corner near close
button) only when at some input parameter is something. i.e. I want to
change dialog box property at run time

How can I get this thing done??

plz help..

When creating the dialog box object, you can set the extened window
style. In partiuclar you are interested in the WS_EX_CONTEXTHELP
flag. Take a look at CWnd::CreateEx and the dwStyle argument. Or if
you don't have access to its creation, you can still modify the style
with the CWnd::ModifyStyleEx method.

Also, you might try posting to microsoft.public.vc.mfc. That group
seems a little more active.
