I bought the book Cocoa Programming for Dummies and it's been very helpful. I'm doing a small program with two sliders. I've been able to get continous feedback in text boxes with them and I would like to know if it's possible to do continous operations using those values. Essentially, I want to continuously calculate the product of the two variables. Thanks.

Of course you can. The code to do this is left as an exercise to the reader (hint: try looking at Apple's Currency Converter tutorial).

I didn't see anything in the tutorial that was of much help. Perhaps I need to explain better. I want to take the values of two continuous sliders and get the product continuously. Now, I can get the product easy enough, I just don't know how to calculate it continuously. Right now I have to select the product box and hit return for it to refresh.

I don't know the example you are doing, but my guess is that you have a slider with a target to a method in some class called say, "sliderChanged".

In the sliderChanged method do something like:

-(void)sliderChanged:(id)theSlider {

[aTextField setFloatValue:[theSlider floatValue]];
}

This code assumes you have a text field called "aTextField". This will put the value of the slider into the the text field.

Hope this helps.

Whenever you update the values, send a message to update the product too.
