Re: Using Python in ActiveX task - works when run as separate step

Well, I've got a bunch of other VBScript tasks running without any issues. I was trying to use Python in this case because I know it a little better than VBScript and it was easier to do what I needed. I will try the auto-generation of a blank function and see if I can run just that as a whole.

The way I defined my task was by defining a Main() function in Python and putting all of my code in there. Do I need to call the function as well or will DTS call the main() function? Do I just need to put my code in there without a function? Can you give me a sample of how you got your ActivePerl code to work? That may give me some pointers.

Thanks for your help.

Hello Pete,

Though it is possible to use different script engine such as perl, Python in ActiveX task, it is not official support.

It is suggest that you use a simple test script ( I use VB script as sample) to make sure if Python can work under this stiaution

Function Main()

	DTSGlobalVariables( "Test" ) = "Test"

	msgbox DTSGlobalVariables("Test")

	Main = DTSTaskExecResult_Success

End Function

You could execute the step in DTS package window.

I ever installed Perl and it works OK. If above step fail, please try to click "Auto Gen" to generate default (blank) function to test.

You should not need to call Main. The UI includes the entry point text box which does this for you. See the "FunctionName" property in BOL, which is what the task calls on execute.

Saying that I could never get other scripting languages to work, but probably my in experience in them, as I believe others have, Perl at least.
