Issue in GetString()

PeterRollier — Thu, 06 Jun 2024 08:24:31 GMT

Hi,

I'm getting a General Function Failure when I try to use GetString in a row.
I can get the field information and type without a problem.
on an integer field I can get the value.

Dim myId As Integer = r.GetInteger("OIDN")
Dim myValue As String = r.GetString("WAARDE")

In the above code the .GetString is nog working, can someone help me what I'm doing wrong?

thanks

I realize this is late help, but maybe it will help others. You need to check IsNull first on desired field:

if (!row.IsNull(fieldName)) { var value = row.GetString(fieldName); return value; }

It applies to all Get* methods.
