How to disable NextPage button in Print Preview.

Hello, 

My requirement is to disable the NextPage button during print preview.
I am doing some processing in CMyView::OnPrint. so I do not want the
user to select next page before my print processing for the current
page is completed.

So, I want to disable the NextPage button in start of CMyView::OnPrint
and enable it back when I'm done with my print processing.

My printing process is highly dependant on sequencial occurance of page
number, so if user keeps on pressing NextPage button, during the print
process of current page, then next OnPrint() will be called for a non 
sequencial page number, which I do not want.

Example : 
If my print processing is done for current page e.g Page No. 1 and user
presses the NextPage button four times, then my next OnPrint() function
is called for Page No. 9 which I do not want to happen.

Note : I do not want to put a WaitCursor here.

What do I need to do ?

Thank you,


ashok

You might try putting in an on update command handler for NextPage. When
you enter OnPrint and want to gray out the NextPage button, set a flag
that the update command handler checks. When finished, clear that flag.

The update handler checks that flag. If it is set, gray it out; if
cleared, pass the message along to the normal handler you have installed
that checks for further pages.

Use CPrintInfo::SetMaxPage() in CYourView::OnPrepareDC().
