Explanation / Answer

Hi,

TryParse will retrun true if the parsing to integer is successful. Please consider below code for verifying if the parsing is true or false. It is working module.

Please follow below steps-

1. Remove below lines from your code-

number1=CInt(txtA.Text)

number2=CInt(txtB.Text)

2. Now use below code for the if ..else logic-

Dim intRes As Integer

Dim result1 As Boolean = Int32.TryParse(txtA.Text, intRes)

Dim result2 as Boolean =Int32.TryParse(txtB.Text, intRes)

If result1=true and result2=true Then

<<<Put your code to compare numbers>>>

Else

lblresult.Text="Invalid Data"

End If

Sample code- I have written this for you to understand the functionality

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim value As Integer

Dim number As Integer

Dim result As Boolean = Int32.TryParse(TextBox1.Text, number)
If result = True Then
Console.WriteLine("Converted '{0}' to {1}.", TextBox1.Text, number)
MsgBox("Translation successful")

Else
Console.WriteLine("Attempted conversion of '{0}' failed.")
MsgBox("Translation Unsuccessful")
End
