View 1 Repliesat the moment I have a small application and need to take information from an object and display it into an excel file, using the Microsoft.office.interop class I've been able to write to the file, and it shows one by one the records being added, however about once every 3 times I try it, the spreadsheet stops filling somewhere between the 300th and 600th record, I have 6,000 in total and it's not breaking every time, I put a check after it finishes to see whether the last record is filled in but the code never reaches that point and I'm unsure of what's happening I also don't know how to debug the problem as it'd mean going through 6,000 loops to check for it stopping... which might not even happen?
