I have a Guess the Number game where I would like to enhance the game a little more by adding when the user is getting warmer, or colder or if they are freezing or boiling... I have no idea how to do this. I have the game to where it is telling you that the user needs to go higher or lower. Can someone please help me??

And also I want a text box to be able to tell how many guesses they have guessed... how do you do that?

Thanks a million!! :)

How about something like
           If intGuess < intNumberToGuess Then

 

                lblinfo.Text() = "Too Low!"

 	  If Abs(intGuess - intNumberToGuess) > 10 Then

               	 MsgBox("Number is Too Low,  And you are cold- Have another go!")

	  Else

		 MsgBox("Number is Too Low,  But you are getting Warmer- Have another go!")

 	  End If

 

            ElseIf intGuess > intNumberToGuess Then

 

                lblinfo.Text = "Too High!"

 

 	  If Abs(intGuess - intNumberToGuess) > 10 Then

               	 MsgBox("Number is Too High,  And you are cold- Have another go!")

	  Else

		 MsgBox("Number is Too High,  But you are getting Warmer- Have another go!")

 	  End If

Abs is coming up with an  error... it says expressions is not an array or method and cannot have an arguement list...
do you know why it could be doing this?

Thanks!

Is this VB6 ?
Abs is a built in function for absolute value

Description
Returns the absolute value of a number.
Syntax
Abs(number)
The number argument can be any valid numeric expression. If number contains Null, Null is returned; if it is an uninitialized variable, zero is returned.

Remarks
The absolute value of a number is its unsigned magnitude. For example, Abs(-1) and Abs(1) both return 1.
The following example uses the Abs function to compute the absolute value of a number:

Dim MyNumber
MyNumber = Abs(50.3)  'Returns 50.3
MyNumber = Abs(-50.3) 'Returns 50.3
