Thanks for that code example, I've adapted it to what I'm trying to do and I'm almost there. However, when I do a sort now it works when it encounters a & e, but skips o for some reason.

I think I just need to tell the sort function sort by ascending order except when you encounter "a" "e" "i" "o" or "u" but am not sure how. Would it have something to do with the p parameter?

Oh sorry, I assumed that STL lists were passed by reference automatically.

Amended code....

Thanks, I assumed <char> but now its outputting the list unsorted.

Is there something that needs to be put it front of ch.sort(); because its inside of a function?

Thanks.

Thanks a lot.

I'm using this code:

Try
While carpetArea <= 0 And Double.TryParse(carpetArea, dblNumber)
carpetArea =...

Just in case this was it, I went to the beginning of the program and found carpetArea declared as a double instead of a single so I changed the while condition to this


While carpetArea <= 0 And...

Ok I tried same code as above except with

carpetArea = InputBox("Please enter the area that you want the carpet installed in:", "Area", "0")

While carpetArea <= 0 And Not...

Also, if it's a letter it still crashes with an invalid cast exception.

Thanks for the suggestion, I went ahead and tried it .
