HELP....using ExtTextOut in VC++

[Azie]

I got a problem using ExtTextOut. I am trying to display text inside a rectangle or circle. When I ran the program it gives me assertion fault. What is causing it? If there are any examples on using this function please let me know...

Thanks a lot.

Hi Azje,


you didn't say anything about the line or the file where the assert occured, so I looked in the MFC source files. The only asserts I found are when the CDC is not created properly so CDC::m_hDC is NULL.

I am using the ExtTextOut in the View file in the OnDrawEllipse class. The only

example that I could find is the one used in OnDraw class.

I want to label the circle(inside). How can achieve this without CDC::m_hDC

being NULL?


Thanks

Hi Azie,


sorry, but I don't found any OnDrawEllipse class or function in the MFC or SDK documentation. There's a OnDraw function in the MFC, a member of the CView class, but there you get a pointer to a CDC class, so you can call CDC::ExtTextOut. If you need to get a CDC by yourself I recommend you to look at the CDC class, especially at GetDC or CreateDC.
