Data integrity is probably the issue. Make sure the values typed in the textboxes are allowed for the underlying data fields datatype. For example, if it is expecting a number, textboxes all return string values and it will error out.
Also, I would get rid of command objects in this case. You just dont need them for what you are doing.
Create a single INSERT statement like you did but remove the "@" place holders and put actual values.
For example:
INSERT INTO MyTable (Field1, Field2, Field3)
VALUES ('Value of field1', 'Value of field2', 'Value of field 3')
Also, I would get rid of command objects in this case. You just dont need them for what you are doing.
I dunno, using a command object like that is safer. It forces correct datatypes and helps prevent against sql injection.
As for the problem, I don't think that is a valid SQL INSERT statement?

You are right. In this case, it's a toss up between letting the code handle exceptions or, what I like to do, check the data integrity before sending it to the db.
You are right. In this case, it's a toss up between letting the code handle exceptions or, what I like to do, check the data integrity before sending it to the db.
The problems are:
a). In your SQL statement you don't specify the fields to insert into - consequently you are required to enter all fields for the table you're inserting into. This means that if extra fields are added in your database, your query will then crash, which is what I suspect is happening to you. Try the following format: - Dim sSql As String = "Insert Into MyTable(Field1, Field2, Field3) Values(@Data1, @Data2, @Data3)"
-
Dim oCmd As New SqlCommand(sSQL, oCon)
b). Your SqlParameter instances don't need the @ symbol when you're creating your parameter object: - oCmd.Parameters.AddWithValue("Data1", TextBox1.Text)
-
oCmd.Parameters.AddWithValue("Data2", TextBox2.Text)
-
oCmd.Parameters.AddWithValue("Data3", TextBox3.Text)
Notice how in my SQL statement I specify the placeholders using the @ symbol, but when I create my SqlParameter instances, I don't use the @ symbol.
If you correct both of these issues in your code, it should fix your problem.
Problem is not with number of parameters.
Which line of code is creating the error ?

The type you pass to your stored procedure must match the type for the parameter. You are getting this error because you are passing a string when your proc expects a different type. You will need to Convert the text from your textboxes to match the type that your parameter expects. - ("@Parameter1", Convert.ToInt32(TextBox1.Text);

Just match the type with your database scheme ...
