Protected Function ProcessSiteImportFile( ByVal SiteData As DataSet) As String Just discovered - that it actually inserts 1 line of data and then gives me a conversion error. It seems that something else causes the error. Since EmplID field is a string - it's OK to have empty string in that field vs Null. What am I missing? About zero string - I just added this check to see if it resolve the error and it didn't help. I tried to insert just 4 fields (all with values) as a test - still getting this error. I specifically left 2 rows in excel without any Nulls and during debug watched every field - had no Null values, yet on the 'ExecuteScalar' command I'm getting the conversion error. The problem is that even if I don't have any Null values in excel file - I still get the 'conversion from type DBNull to type String' error and I don't understand why. I'm trying to insert data from excel file into SQL using Visual Basic project. I'm half way there but stil have a problem. Welcome to the All-In-One Code Framework!
