Problem with DOS Batch file

Hello

My solution will not work:
For a exotic Labelprinter I have to send Binary data direct to the printer.
I do this creating a File with the data.
Then I create a DOS Batch file as follow:
Cmd is string = "c:\windows\system32\LPR.exe -S " + Computername + " -P " + Printername + " " + Filename + " -ol"
an write it to my disk: fSaveText("C:\Temp\Batch.bat", Cmd)

This Batch can I start manualy without any problems, it works.
But unfortunately I am not able to start the batch by WinDev
I tryed 'exerun', 'DDEstart' (DDEStart("C:\Temp\Batch.bat"))
whatever i try, it does'nt work

Anybody can help me ?

Thanks in advance
Erich

why use a batch file when you can do an exerun direct of LPR.exe?

Anyway, your problem is most probably a rights problem... Try running your exe as administrator, that may solve it

Try with EXERUN or SHELLEXECUTE instead of DDESTART

Hi Erich,
run the "LPR.exe" directly.

The following works for me with a spool printer ...
j=ExeRun("c:\temp\spool.exe Rep8.txt",exeActive, exeDontWait, "C:\temp\")
