Hi,
I want to start a DOS batch file from a project with the path %X.
run -e %XBatch.bat
Only if I started the Origin project by double clicking then the batch file will be started from directory %X.
However, when I start Origin and load the project the command starts the program in the Origin directory %Y.
I tried fdlog.path$=%X but without success.
Any ideas how I can set the DOS window start directory?
Thanks, Tilman.

Hi Tilman,
You can't change the working directory from LabTalk, but you can from Origin C. I'm not positive that this will do what you need, but it might be worth trying...
# OC function
int ChgDir(string strPath)
{
return _chwd(strPath); // change working directory to strPath
}
# LabTalk usage
if( ChgDir(%X)==0 ) run -e Batch.bat;
(Now you don't need the full path in the run argument.)
...You might as well do it all in Origin C
# OC function
void Launch(string strApp)
{
string strPath = GetFilePath(strApp); // file path
string strFile = GetFileName(strApp); // file name
if( _chwd(strPath)==0 ) ExecuteApp(strFile,"");
}
# LT usage
Launch "%XBatch.bat";

Hi Mike,
thanks, I would have preferred the pure C solution.
BUT it doesn't work.
First the command _chwd should be _chdir.
And OriginC seems not know the command ExecuteApp.
I also couldn't find it in the help.
Your first example works only if I replace
_chwd with _chdir
Tilman.

Sorry, mixed up the function name with the name of the example given in the help file.
ExecuteApp is Origin 7.5.

Hi,
I had several problems with the calling of
batch files from a LabTalk script and sometimes
the same script does not work the same way
in different machines.
Concerning your example I guess I was luckier
by inserting the character '\' between the
string variable %B of the path and the batch file name:
run -e %B\BatchFile.bat;
Good Luck!

Hi Ricardo,
Whether or not you need the final '\' depends on how the path was generated. Most LabTalk commands that return paths automatically append '\'. Examples... %B=fdlog.path$, %B=%Y and %B=%X. (Although %X is empty until the project is saved.)
