I am relatively new to the C++ world - I am working on a form control that is supposed to use a List box to pull a value out of an array of values and display it in a text box.
This is way above my head, but I want to figure it out.
Here is my task:
1-Write a program for Eddies Equipment Rental
2-Build a windows form that looks like this:
3-Eddie Charges one amount for full day rentals and another amout for half days.
4-Use 3 parallel arrays to store the data
Data is as follows:
5-Load the list box during the form load (optional)
6-The user should click on the item in the list box to select the equipment GOT THIS
7-the user must enter an f or h for full or half day GOT THIS
8-the Display Charge button will display the approrpiate amount in the rental charge text box I really need help with this.
the Clear button will clear the 2 text boxes GOT THIS
I have the form built - and the clear button working.
I have the listbox issueing values based on selection - but don't know how to put that data in to an array that is also getting data from the Duration Text box. I actually am not sure how to get the data outside the function itself. To use it with the click function of the Dsiplay Button.
I got the txtDuration to validate input - and it uses a message box to alert the user if they input the wrong thing. Though the built in error handler is a bit annoyoing - if you hit the backspace the program throws another error message box - that I didn't program, would like to turn that off. it tells you that you must have exactly one character - which is not necresary.
Alot of the problem I am having is that I don't know where to put stuff - when there is already a ton of code generated that I don't understand.
Any help would be greatly appreciated.
code for form that I have already is below:
