Am using Vb.NET 2008 and SQL 2008. I have a problem, when the execution reaches daAdapter.Update(dtTable) then I receive this error ""String or binary data would be truncated.
The statement has been terminated"" Then the record fails to update. What could possibly be the error? Below is the complete code. Thanx in advance.

Dim SQLCon As SqlConnection

strServerName = GetSetting("Lands", "Connection", "DataL3")
strInitialCatalog = GetSetting("Lands", "Connection", "DataL4")
DataL1 = strUsername & strPassword & strServerName & strInitialCatalog
dTable = New DataSet

SqlQuery1 = "select * from FileRegister"
daAdapter = New SqlDataAdapter

SQLCom1.CommandType = 1

SQLCom.CommandText = SqlQuery
SQLCom1.CommandText = SqlQuery1
daAdapter.InsertCommand = SQLCom
daAdapter.SelectCommand = SQLCom1
daAdapter.Fill(dTable, "FileRegister")
dtTable = dTable.Tables("FileRegister")

I receive this error ""String or binary data would be truncated.
The statement has been terminated""

You have, for example, a field of type Varchar with size 100 and you're trying to insert a string value which length is longer than 100.

For text boxes you can set the Maxlength property to match the lengths in your DB. Over all you should validate user input and give a warning if the user is trying to enter data that does not match with your DB.
