Figure 11-10. By using ADO.NET capabilities to assign values to form control properties, you can create richly interactive forms. The following excerpt is from the top of the Button3_Click procedure. This excerpt assigns the value of the Text property for TextBox3 to the str1 String variable before passing the value of str1 to the IsInteger function procedure as the argument of an If clause in an If...End If statement. If the IsInteger function procedure returns a value of False, the Button3_Click procedure displays a message box about inputting an Integer value for the ContactID column value before exiting the procedure. Dim str1 As String = Me.TextBox3.Text 'Verify that an Integer value is input and is in 'proper range of values If IsInteger(str1) = False Then MessageBox.Show("Please input an integer as an ID value.", _ "Warning notice", MessageBoxButtons.OK, MessageBoxIcon.Warning) Exit Sub End If The test in this section for identifying a String value as representing an Integer value is more rigorous than similar code in the Returning a Value in a Windows Application section. The next listing is the code for the IsInteger function procedure. Instead of just verifying whether the str1 String value can convert to an Integer data type, this function procedure also verifies that the CDbl transform of str1 equals the CInt transform of str1. Unlike just using the CInt function by itself, this test about the equality of the CDbl and CInt function values correctly detects that 2.2 is not an Integer data type value. Using CInt by itself cannot rule out 2.2 as an Integer data type value. Function IsInteger(ByVal str1 As String) As Boolean Dim int1 As Integer Try int1 = CInt(str1) If CDbl(str1) = CInt(str1) Then Return True End If Catch ex As Exception Return False End Try End Function

Using the command when you are logged in to another computer via ssh works in exactly the same way. Let s consider an example. Assume there are two computers: A and B. You have a user account on each one. So sitting at the keyboard of A, you establish an ssh connection with B by typing the following:

The second check for the value in TextBox3 ties together tightly with the code to return the ContactName and ContactID column values, as well as the code to enable the control for editing column values and deleting rows After the check for str1 being an Integer data type value, the Button3_Click procedure invokes the InColRange function from Form2 This function was originally discussed in the Returning a Value in a Windows Application section Then, a Select Case..End Select statement processes the return value from InColRange (strReturn) In the event of a Value in range return value from InColRange, the procedure uses a SqlDataReader to extract the ContactName and ContactEAddr values corresponding to the ContactID column value in TextBox3 The procedure assigns the retrieved values to the Text property values for TextBox4 and TextBox5 The procedure also invokes the Sub procedure named DisableEnableUpdateDeleteControls with an argument of Enable.

This lets you log in to B as if you were sitting in front of it. You spot a file called spreadsheet.xls that you want to copy to your local machine (A). You therefore issue the following command:
