Interface Labview -> DLL with Parameter (char *argv[]) as a 2D string Array

[mk@FHI]

Dear All,

I have a DLL compiled by myself with a Parameter char *argv[]

_declspec (dllexport) int elog(int argc, char *argv[])

this was a comandline program with text Paraneters:

elog -v -x -test

and itwas working fine

Now I do not know how  to pass this command string with labview to the DLL, a normal string is not working.

It seems to be a 2D String to be passed:

 if (argv[i][0] == '-' && argv[i][1] == 'v')
         verbose = 1;

Thank for help!

Best Hepman

Try the LabVIEW code in the snippet below, taken from: http://lavag.org/topic/14642-passing-array-of-string-to-c-dll/#entry87758

This shows how you can pass an array of LabVIEW strings to a DLL. Note that what you have is an array of strings, not a 2-D array of strings. Your C code treats it as a 2D array of characters, and it works due to the way C dereferences pointers.
