I'm using the .dll with Visual Studio 2008 and I'm programming in VB.
If I try to write numeric or date values to the cells, everything works fine.
If I try to write string values to the cells, it appears to work fine, but when I try to open the resulting file I get an error message that reads: "Excel found unreadable content in [name of .xlsx file]. Do you want to recover the contents of this
If I choose "yes", the book opens, but every cell that should have a string value is completely blank (the other values are fine).
Thank you, in advance, for any ideas you may have.
