Should i use .net or VC6 itself? I'm planning to use VC6 itself bcoz it has many dependencies which are in vc6 and uses 3rd party dlls also.
If using VC6, should i create using ATL COM appwizard -> Service.exe or simply create a cpp file for service?

Will the SetTimer function restart then the UINT uElapse// time-out value is reached??

What function can I use to make an interval timer??

This is what SetTimer is for

I do this by overriding the OnSize message handler of MFC and I then just get the client rectangle of the dialog and then draw the lines with this new rectangle applied.

I get the client rectangle in the OnSize message handler, and then compute the new dimensions of the two lines

All I do then in the OnSize()-method is a call to Invalidate

But anyway I have to put an Invalidate() into the OnSize handler, because without that I see the changes only after hiding and showing again the dialog.

I don't really understand why this has to be done by a HDC

Does anybody here has a complete program of Circle Equation?

Somethings seem HARD to do, until we know how to do them.
