Database Adapter Error in VB.NET
I am getting this error:
An unhandled exception of type 'System.NullReferenceException' occurred in 8.exe Additional information: Object reference not set to an instance of an object. Which points at this piece of code: DBCareerAdapter.SelectCommand.CommandText = strSelect & _ strWhere & CStr(intminatbats) & " " & _ strOrderBy Can anyone tell me what the error means or point me in the right direction? My strings are not empty...and I have delcared the adapter beforehand. Thanks

1) This belongs in the .NET area of the forum
2) It would help if you told us what strSelect and strWhere was? 3) Quote:
Means that you are trying to reference an object that you haven't instantiated. Example This will throw the above error Code:
Declare the variable as a type Dim x As Object You can't do this because you haven't created the object yet. x.Property = Value This will work Code:
Declare the variable as a type Dim x As Object Instantiate it (create it) x = New Object x.Property = Value
