Opening a text file as readonly within an MDI

361 Views

Dear Members,

I am learning about creating GUIs in CVF from the book by Lawerence. I am on the chapter which introduces MDIs and I would like to open a file as read only, such that the user cannot edit the text in the window at all. To accomplish this, I tried setting the OFN_READONLY flag in the openfilename structure and while this checked the read only check box in the open common dialog, i was still able to make changes to the document.

Also, I am unclear on the use of the logical variables 'lret', 'iret' and 'bret'. When should they be used and why?

Any assistance with this issues will be greatly appreciated

Regards
Chandrika
