checking variable values, CString conversion, and DC pointers

[joelwenzel]

Hi,

I am wondering how I can check what is in certain variables in my program. I want to be able to just convert whatever variable I have and print it to the screen. So I have two problems

1. I need to somehow get a pointer to the device context from any function so that I can write using TextOut(0,0, mystring).

2. I need to be able to convert any kind of variable to a CString

Any ideas. I'm sure this is an easy question but I cannot find the answer.

It sounds like you could just use the debugger if all you need to do is check the value of a variable. If you don't know how to use the debugger, you should definately learn; it will save you hours of debugging time.

But if that's not all you really need to do, you can get a pointer to the DC with the CView::GetDC() method. Don't forget to release it with ReleaseDC() when you are done. To convert any other data type to a CString, just use the CString::Format method. If you've never used it before, it is basically sprintf for a CString and is very handy.

Thanks a lot. I will looking into using the debugger more.

Plus, I need to know all that conversion stuff anyway
