RUN, maximum length of command?

[Polyphem]

Hi,

i call a program with parameters via RUN(). The number of parameters is variable. At a certain point, the RUN command just stalls...

e.g. "test.exe param1 param2 param3 param4" works, but if i add up to 50 parameters and the command line is getting really long, the RUN command does not work. Is there a maxium length? And maybe any way around it?

Thanks and Regards

Any of the parameters has blank spaces. Any parameters with blanks space need to be between quotes (")

test.exe param1 param2 param3 param4 "param 5" "param 6"

Thanks for the reply. Thought about that allready, all quoted. It only has to do with the length? Is there a 256 character limit? The parameters are in a variable. Currently i write the command to a temp .bat and start that. But thats only an imperfect work-around.

I'm not aware of a limit myself, and I couldn't find it in the docs either.

If this is an AutoIt App, have you looked at possibly $CmdLineRaw? And maybe just parsing from the other app?

Currently i write the command to a temp .bat and start that. But thats only an imperfect work-around.

If the same command runs from a batch file it will run from autoit too.

I will use ConsoleWrite() to double chech the run() syntax.

Ex:

ConsoleWrite('test.exe param1 param2 param3 param4 "param 5" "param 6"' & @CRLF)
Run('test.exe param1 param2 param3 param4 "param 5" "param 6"', @TempDir)

There used to be a limit on the char length of all parameters together. So if StringLen($params) > 512|1024|4048 or what it is today you could possibly be in trouble. Not sure if this applies to XP (or Vista)
