Printing Debug Output in Windows Programs

Question

I am starting to work with the Windows API. However, I noticed that you cannot use functions such as printf if you have a windowed application. What is the standard way to print debugging and logging information? Sorry if this is an obvious question.

Answer 1

I usually use OutputDebugString() , the API here . During application startup, you can view the results of this function using DebugView from SysInternals or in the Visual Studio output window during debugging.

Answer 2

Options:

• Create your own class that registers in the file
• Create a list view or edit a control , and add text to it
• Use OutputDebugString
• Create a window
• Windows Event Tracing (not for general logging)
