hi.......
 
When i am using libpq on .net (vc7) I am getting the following errors.Mine is a simple C program in which just trying to
connect to the database and testing it for connection.This Application also includes so many other functions.
Anything wrong to include postgres in such an application......
I tried in someother application which deals with only postgres function.....It worked fine.When i added this in the above mentioned application I am facing problems......
 
Without including libpq.lib in (project-> properties->Linker->Input->Additional dependencies )
I just started learning to work on MFC/.Net
Please suggest me how to proceed
