So I have my program running with input from a file:
ie Project Menu -> Properties -> Debugging -> Command Arguments -> I have:
Code:< inputfile.txt
The program works fine when I run without debugging. It loads the input from the file just fine...
Now, when I want to debug, and stop at breakpoints etc, it *IGNORES* that file completely.
Why? Is there any way to debug WITH command line arguments (input from file)?
I seem to recall that you might not be able to redirect input when running through the debugger for some reason. Regular command line arguments will work fine. Were you able to search for anybody else with the same problem?
Hmm, wow... That sucks. Pretty big feature to lose out on... Unfortunately no, even tried Google.Quote:

I don't know. This was the first hit when I searched for "redirect input Visual C++ debug":

It seems to indicate there might be a bug, but I don't have time to test it or search further at the moment.
Ahhhh s h * t
There has to be some kind of a workaround?
One workaround would be to add something like "for(;;);" to the start of your program, execute it from a command prompt, and then once the program it running, attach your debugger to the running proces and move the execution point to the next statement.
Oh wow... Trying this...Quote:

Take the yellow arrow and drag it to the line you want to move to.
Yellow arrow? Is this in a menu or a toolbar?Quote:

First, break the program (press the pause button).
A yellow arrow will point at the line it's currently at (it's to the left, where you can see the breakpoint).
Grab it and drag it to the line you want to move to.
If it pops up some dialog after you do, simply dismiss it with OK.
Wow, you guys on these forums are geniuses, haha!Quote:

One issue (with Visual in general I guess), is there a way to get it to not step into the C++ stuff for every cin and cout? (Not my code)
Also, just curious, how does Visual C++ know that the process I am attaching to is the exact same as the one I have open when I click debug?Code:template<class _Traits> inline
basic_ostream<char, _Traits>& __CLRCALL_OR_CDECL operator<<(
basic_ostream<char, _Traits>& _Ostr,
const char *_Val)
{ // insert NTBS into char stream //<--- steps in on this line every cin and every cout
typedef char _Elem;
typedef basic_ostream<_Elem, _Traits> _Myos;
ios_base::iostate _State = ios_base::goodbit;
streamsize _Count = (streamsize)_Traits::length(_Val); // may overflow
streamsize _Pad = _Ostr.width() <= 0 || _Ostr.width() <= _Count
? 0 : _Ostr.width() - _Count;
const typename _Myos::sentry _Ok(_Ostr);
etc...
Man this is awesome!!!! Thanks guys!!!
For the quick first question: use step over (F10 with the VS6 scheme).
Using step over should work for most of those issues. However, you can also make step into skip certain functions by editing a config file. It's somewhat complicated and I'm not 100% it is cstill available in VC++ 2008, but it's worth looking up if you want more options for the debugger.
Oh yeah! lolQuote:
