Creazy Commandline

[jumbojetjames]

hi all,

I have a problem with the commandline-args using CVI901. never had such a behaviour.
I give a string like "1 2" at the commandline to my program.
the intellisense-help tells me, that I have a argc=3 - just like awaited. but the software seems to have an argc-value of 5. If I put the value to the console a 5 appears and the software is just working this way. totally confused! I attached a screenshot.

any idea ?

best regards

Simon

Hey Simon - 

That's a pretty baffling picture you've got there...  A couple of us have tried to reproduce what you're seeing, and none of us have been able to.  If you do something like this: 

while (--argc)
    puts("Test");

do you get 3 Tests or 5?  Also, what happens if you explicitly do this: 

printf("The parameter-number is %d!!!", 3);

Also - are the results the same if you use sprintf instead of printf?

Finally, do you think you could post a very simple example that reproduces this on your machine?  Also, be sure to include both the .prj file and .cws file so that we can make sure we are matching all of your configurations.  

Thanks!

hi nick,

just this morning I switched on my computer and cannot reproduce the effect. but I saw this yesterday in two projects using the commandline (and was not drunken). anywhere - I attached the project which made the creazy picture I sent to you yesterday as a zip.

best regards

Hi folks,

I got interested by this post an tried it my self with the zip file data. And I cant reproduce it either. System is CVI 9 on WinXP.

 calling line in Commandline: cmdLine_dbg.exe 5

answer of the program:

 I've inserted a simple getchar() to keep the command line up.

Hope you figure that out. Greetings Martin
