I have an assignment for uni. I'm to create an app that shows a shape selected from list within a combo box.

I have entered the

following items in the OptionComboBox

Square
Circle
Triangle

My overall design was

OnChange
if selection = square then
   displaysqaure
else
   if selection = circle then
       display circle
   else
       if selcetion = triangle then
            display triangle
       else don nothing

Guidance on how to use the combo box and it events would be great.

Thanks

The code you've posted above bears little resemblance to C++.  Are you programming in C++ or some other language?

In that case I think you need to work on this a bit more yourself.  The Experts Exchange site policy prohibits experts from doing your homework for you.  It's one thing to say, "please look at what I've done and help me figure out why it does this vs. what it's supposed to do."  But you're basically saying, "I haven't really done anything, please do it for me..."  That's not what this site is about.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Hey  Levi101

jhance has a point.
but still if you need a jump start, and as I suspect this combo box, is not the heart of the project, I will try to assist:
1) first what OS are you using? (your pseudo code smells like VB which is a hint towards windows, but it is not clear)
2) if the OS is clear, are you using any GUI library ?(MFC, ATL, DotNet windows forms etc.)

answer those, and you'll get the start point for your project

I'm not asking you to do my homework, I am simple asking for guidance on how to use the Onchange property of the combobox. I could use buttons or even a menu. However i feel it's cleaner if i use a combobox. I have refered the borland help and draw a blank. If it makes you feel any better the the bit I'm strugling with is the variable selction ie.
if user selects options one, where is the variable and how do I use it eg if (SelctionV = OptionCombo->item->Option 1);

I'm using borland C++ and its libaries, the OS is windows.

Hey Levi101

I think your syntax will be something of the form:

ShapeString = ComboBox1->Items->Strings[ComboBox1->ItemIndex];
