Resolved [2005] DIm statement twice

[int3gral]

do i really have to declare a variable twice

IF intTemp > 32 or < 95 (because doesn’t state if these temp included too) Then
lblWarning.text = “Normal Temperature”
End if
that is wrong


im assuming the following is corrected because it doesnt say that there is build time errors.


If inttemp < 95 And inttemp > 32 Then
lblwarning.Text = "Normal Temperature"
End If

That's not declaring a variable twice. This is a declaration:

Dim intTemp As Integer

This:

If inttemp < 95 And inttemp > 32 Then

is simply referring to a variable twice and yes, you do have to do it twice. The operators And, Or, AndAlso and OrElse require two Boolean operands. In this case:

If inttemp < 95 And inttemp > 32 Then

you have two Boolean operands, i.e. (intTemp < 95) evaluates to a Boolean value and (intTemp > 32) also evaluates to a Boolean value. These two Boolean values are the operated on by the And operator and all is well. In this case:

IF intTemp > 32 or < 95 Then

(< 95) is not valid expression so you get a syntax error. VB provides no shorthand for what you want to doand nor should it. If it did then it would simply make complex Boolean expressions unreadable. If typing the variable name twice tires you out then lie down for a while.
