Brian, Sorry I've screwed up in my advice to you. I've suddenly remembered that my problems were down to attempting to use excel as a datasource, with an insert, then subsequent read of the newly calculated value. This resulted in similar symptons to your problem, whereby it worked first time round but subsequent calls simply returned a cached result.
Using COM to do the insert was my workaround to the problem, plus I used the disable dbconnections commands as an extra measure on the datasource before invoking a DTS package in SQL 7 to retrieve and record the relevant result. In which case the placement of the tags are actually BEFORE calling the sheet (as a datasource) with the DTS package. Your problem is that you appear to be experiencing excel locking up even when connecting via COM in the custom tag. I suspect you dont even have the sheet set up as a datasource.

I placed it after the call to the custom tag that creates the csv file. Does it need to be before or wrap around the call? <cf_excel2csv excelFileIn="C:\Inetpub\wwwroot\clients\mysite\import\uploads contracts2.xls" CSVFileOut="C:\Inetpub\wwwroot\clients\mysite\import\uploads\ExcelFile.txt"> > <CFSET CFUSION_DISABLE_DBCONNECTIONS("datasourcename", 1)> <CFSET CFUSION_DISABLE_DBCONNECTIONS("datasourcename", 0)> Thank you very much for the help.

To fix the problem of inactivity in the excel part of the process on subsequent attempts, use the following: <CFSET CFUSION_DISABLE_DBCONNECTIONS("datasourcename", 1)> <CFSET CFUSION_DISABLE_DBCONNECTIONS("datasourcename", 0)> Which should help to kill any locked connections to the sheet. HTH, Dave -----Original Message----- From: Brian Ferrigno [mailto:[EMAIL PROTECTED]] Sent: 30 September 2002 16:40 To: CF-Talk Subject: COM help I need help tracking down an error in using CFOBJECT to create a csv file from an excel spreadsheet. I am using CF to open up an excel spreadsheet and then trying to turn the data into a csv file. The code i'm using works fine the first time the application is launched but on subsequent tries nothing happens. According to the company hosting my site COM is causing the CF service to fail then it has to be restarted. I'm listing the code i'm using below. Is this an issue with a patch needing to be installed or a problem with the code below? Any help would much appreciated.
