.xlms Excel file error while uploading using vb.net

Question

I try to upload a .xlms file, but when i click upload and after i click button

My program doesn't come in debugging mode or upload the file

Check this image below please

So why if i upload a .xls file it works, but if it is a .xmls file it displays that error.

Thanks

The two file types you are testing are quite different, .xls is the old MS Excel binary file format while .xlms is the Office Open XML format, in this case with macros embedded in the file (otherwise it would be .xlsx). Does your tool's documentation say it can handle the new file format (MS Excel 2007 - 2013)? — GeorgDangl

Is your .xmls file bigger than 4 MB? Try to adjust the following attribute value in web.config.

<system.web>
  <httpRuntime maxRequestLength="1048576" />
</system.web>
