I am having a problem. I have a project "MicroSIP" which is used for SIP based call voice over IP. I am running it into VS 2010 and I need to customize it according to my need. For this as soon as I edit the main dialog ( Dialer ) and add some other controls ( like edit control of CEdit) and add member variable for from wizard of "Add Variable", it shows the message "unable to update DoDataExchange method".
More over if getting reference of newly placed "Edit Control" in the program , it has NULL pointer or undefined reference.
Anybody having any idea about this to resolve or some way around to resolve the issue. I am having extremely trouble for solving this scanario.
