   ByVal Index As Integer _

Exceptions

Exception type

Error number

Condition

ArgumentException

5

str is Nothing, Index < 1, or Index is greater than index of last character of str.

See the "Error number" column if you are upgrading Visual Basic 6.0 applications that use unstructured error handling. (You can compare the error number against the Number Property (Err Object).) However, when possible, you should consider replacing such error control with Structured Exception Handling Overview for Visual Basic.

Remarks

If Index is less than 1 or greater than the index of the last character in str, an ArgumentException is thrown.
