data type

If STATUS is a string and I have this code:

Dim status as string = 5
If status <= 7 Then
   go here
end if

why does this code see the IF statement as true, since STATUS is not an integer?

just wondering...

[dynamic_sysop]

you mean like this? :

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim status As String = 5
        If Convert.ToInt32(status) < 7 Then
            MessageBox.Show("the value is less!")
        Else
            MessageBox.Show("the value is more!")
        End If
    End Sub

I think it attempts to convert it and fails so it uses the default value of 0 which is less than 7 making the statement true.

Edneesis, thats makes sense...but say I have this code instead:

Dim status as string = "5"
If status = 5 Then
   go here
end if

it still runs the IF statement as true...if 5 is a string, how can it equal an integer?

The answer is "Implicit Datatype Conversion"

[Edneeis]

You can use Option Strict to force implicit conversion as eshaanye said. Or as long as the string is meant to contain a string version of a number than you can use the parse method of an integer to convert it.

Dim status as string = "5"
If Integer.Parse(status) = 5 Then
   go here
end if

that'll do...thanks
