printout statements

[wongjoekmeu]

Hello all,
I have a C++ program written as a CWinApp which compiles but somewhere
has an error. I use the visual studio .NET compiler by the way. I am
use to programs written in unix environment. Because the program has an
error I want to use print out statements using cout to check values of
my variables. But the problem is that I do not have a console where it
prints out the value. How do I check now the value ??? Thank you in
advance for your help.

You will need to ask this question in a forum dedicated to your Windows
compiler. Here only the C++ language itself is discussed, which does not
cover those special issues of Windows programs. If you go to the Microsoft
web site and look for the newsgroups, you will find many there.

Use 'OutputDebugString' together with 'sprintf', the string will be output
to the debugger window (RTFM on it). And questions on debugging Windows
applications are better asked in a Windows programming newsgroup (like
comp.os.ms-windows.programmer.win32). Here such questions are off-topic.

Why don't you have one?

How do I check now the value ???

Redirect the output to a file. Under linux, you can do:

../myprogram > file

to write the result into a file. Or you can instead of to cout write it into
an fstream within your program.

Technically you are off-topic because your question is related
to how a specific compiler under a specific operating system works.
So next time ask in a Windows programming group.

However:
* Visual Studio comes with a good debugger. You should not have
problems to use that. The debugger can show any variable.
Just position the caret on the variable, right click and select
'Quick View' (That's how it worked under VC++ 6.0, but I guess
.NET is not much different)

* When you have your debugger running, check out the TRACE macro
This comes in handy, if you regularily need to output great amounts
of debug data.

* If all else fails, you can always use MessageBoxes to pop up
a quick and dirty output dialog.

Try outputting your messages to a text file.
This will also show the messages in the order they
were executed and you don't have to mess with any
extra windowing stuff.

And sending text to a text file is _standard_
C++.
