running program with piped input from visual studio

[michael83]

I have a fortran program that reads data using read(5,*) statements. I can compile and link it with IVF and can run it from the command line using a command like:

myprog.exe < input_data.txt

Is there some way to do this in Visual Studio? I've tried a few different run options but nothing works. I'm running the 8.1.019 version of IVF and the standard 2003 C++ .net visual studio.

Thanks.

Project Properties.General..Debugging..Command Arguments - put in "< input_data.txt" (no quotes)

Note that the default directory is that of the project.

I tried this and it did not work. I put some getarg statements into the program. When running from Visual Studio getarg picked up
"< input_data.txt" as an argument but the program still hung while waiting for standard input. When running from the command line getarg does not pick up anything put the program does read in the file.

I think Steve's wrong in this regard -- redirection isfeature of the command interpreter (cmd.exe) rather than the process itself.

You need something like:

Executable for debug session:

C:Winntsystem32cmd.exe

Program arguments:

/c D:UsersDujaCodeBrisiDebugTest.exe < Test.txt

This did work in CVF/VS6. I have not yet tried in in VS.NET - it should be the same.

Ah, sorry Steve -- it does work indeed.

Hi,

I'm not sure how you guys got Steve's suggestion to work. I'm running in Windows XP, service pack 2. That may be making a difference.

But I tried your suggestion, Jugoslav, and that worked (except that I had to substitute WINDOWS for winnt).

Thanks.

I can't get it to work in VS.NET either. Hmm. I will have to research this when I get back to the office (I'm doing training off-site this week.)
