Can you post the powershell script?

you should  be able to run it from a batch file just like running from a powershell console. in the batch try somethign like this followed by any paramenters you need.

powershell.exe  C:\Test\My Folder\test.ps1

Can you post the script?
it depends on your env path, you may need the full path to powershell.exe
the default is
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
then depending on what parametes the script needs you can put them after the ps1 file.

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe C:\Test\My Folder\test.ps1 -file c:\temp\temp_file.bmp

My script has no problem, I do not need to do anything to it, what I need is to call my script from a batch file and pass it a parameter

ok, then depending on what parameter needs past you can do what I posted before. It will all depend on how the script is written.

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe C:\Test\My Folder\test.ps1 -file c:\temp\temp_file.bmp



didn't wotk, since it would capture the "-file" as a first argument.  

I am calling my batch file from another program and I send it a file path as a string, so my batch has the following code:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe C:\Test\My Folder\test.ps1 %1

and it works if the file passed to batch does not contain spaces, otherwise I need single quotes around it

for instance

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe C:\Test\My Folder\test.ps1 %1

only caputres part of the file: C:\Program

so I need to run

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe C:\Test\My Folder\test.ps1 'C:\program Files\Test\my_file.bmp'

and then it works.  But the difficulty is in batch file I get it from somewhere else, so I have to pass it as %1

that is why I wanted to see the PS script.
You can also add this

Param(
$File)

than you can pass -file

I will have to do some testing, i have never tried to pass params through a batch loop to powershell.
