I have a very strange issue that I cannot seem to find an answer to online.
I have a
VB.NET application that creates an
Excel of data (roughly 42,542 rows in total) and the saves the file to a folder location & opens it on screen for the user.
The onscreen version & folder version is only showing 16,372 rows of data like it is being cut off.
When I go through debug I can see all the rows are being added & if I save manually in debug all the rows save. Some data seems to get lost on the system save.
I am taking data from 4 record sets & writing each set one after the other with specific headers for each block on the Excel sheet.
My save line is:
Would anyone please have any ideas as to what this might be?
Older version of Excel only support 16,384 rows per worksheet. You are saving as Excel7 (which is Excel 95) and has this limitation:
See here for a summary of sizes per version:
Change your code to another format, See here for all the allowed formats: XlFileFormat Enumeration
However the file format is actually an optional argument in the SaveAs method, so you could leave it off altogether: “For an existing file, the default format is the last file format specified; for a new file, the default is the format of the version of Excel being used.”
