I'm trying to export a number of tables with a variable number of fields and field names to a tab-delimited text file using VB code. If I use the TransferText method, I can only export to a comma-delimited text file if I do not have an export spec. I tried to create an export spec on the fly by inserting records into the MSysIMEXSpecs and MSysIMEXColumns tables, but I get an error if I try to make these tables not read-only. Any ideas?
