Runs Commands in order

[newkid]

Hi, I'm using Windows Forms C++. I'm getting the user to add commands to a listbox then they click on a button and this runs the commands in the listbox. The problem I have is, I don't know how to run these commands from an index number because they are currently being run in the order shown below and not in the order of where they are in the listbox. Does anyone have any ideas? do { if(lstCommands->Items->Count > 0) { if(lstCommands->Items->Contains("Move forward")) { protocol_test(2, distance, 0); } else if(lstCommands->Items->Contains("Move Back")) { protocol_test(3, distance, 0); } else if(lstCommands->Items->Contains("Turn Right")) { protocol_test(4, distance, degrees); lstCommands->Items->Remove("Turn Right"); } else if(lstCommands->Items->Contains("Turn Left")) { protocol_test(5, distance, degrees); } } else if(lstCommands->Text->Empty) { MessageBox::Show("No Commands selected","No Commands",MessageBoxButtons::OKCancel,MessageBoxIcon::Exclamation); } } while(!lstCommands->Items->Count == 0);

Yes. An Object Oriented Design would be far easier to understand. In this regard finding errors would be relatively simple.

If/then and switch statements are the simplest form of instance –specific behavior….
The more paths through a program the less likely the program is to be correct….
The proliferation of conditionals reduces reliability….
This problem is compounded when conditionals are duplicated.

These problems can all be eliminated by converting the conditional
logic to messages, either with subclasses or delegation.
