>>Hi,

>>An automation process that used to work is now failing, in Excel 2010, for security reasons. Apparently Excel finds the idea of being automated to open an Excel file suspicious.

>>copy to (lcTempFile) type XLS
>>...
>>loWorkbookTemp = This.oExcel.oApp.Workbooks.Open(lcTempFile)

>>Excel - if it was previously open - says something about the trust center (similar to the message below, shown in Visual FoxPro).
>>
>>After accepting the message in Excel, Visual FoxPro gives the error message "You are attempting to open a file type that is blocked by your File Block settings in the Trust center..."
>>
>>I have used COPY TO ... TYPE XLS to make an Excel automation faster - transfer an entire DBF at once - since transferring one cell at a time would be exceedingly slow, especially for large files.

>>Any ideas, how best to handle this?

You can set lower values by enabling the Developer tab ( http://www.peppercrew.nl/index.php/2010/06/enable-vbamarcos-in-excel-2010/ ), then going into "Macro Security" and experimenting with the options.

Thanks. We managed to allow configure Excel so that it allows opening the files through automation - but this is not an ideal solution, since it requires configuring Excel at every client site. Also, I prefer to keep the security options, since they are pressumably there for a reason.
