Hello Again, I've been working on a Zope application and one of the tasks is to integrate the web reports with Excel. I've got some financial reports that the user can browse through using a web interface. What I'm trying to do is have a link on the page that will download the report they're viewing into a local Excel worksheet. I decided to use com because I want the worksheet to have colors, print settings, formatting, etc. I already have working code in VB. I've looked into XML and Pyxlwriter but it looks like a new learning curve compared to just translating my VB com commands into Python. I'm using Visual Studio .Net 2003 with Active Python as my development environment. When I submit the URL that creates the XL worksheet in development, it works like a top. In testing, I've generated 50 different worksheets without any problems. When I try to run the same code in Zope I have problems. Under Zope, I take the submitted URL and create a worksheet that I save to a file. Then I return a meta command to redirect the browser to the newly created file which is downloaded to the users computer. The good news is that it works perfectly - sometimes. Other times I get this error message; Module ExcelReport, line 48, in __init__ Module win32com.client, line 95, in Dispatch Module win32com.client.dynamic, line 91, in _GetGoodDispatchAndUserName Module win32com.client.dynamic, line 79, in _GetGoodDispatch com_error: (-2147221008, 'CoInitialize has not been called.', None, None) The error message is coming back from the line; XLApp = Dispatch("Excel.Application"). The really strange thing is that the error seems to be random. Sometimes it works, sometimes it doesn't. I haven't been able to determine any rhyme or reason to it. When I restart Zope, it will work one to as many as 10 times. Then I'll get the error message. If I keep trying the same URL, it might eventually work or I may have to restart Zope to get it working again. Does anyone have any idea as to what's going on here? Thanks, Joe Goldthwaite
