CListBoxSafe is a class that can save data from a listbox to file and load data from a file into a listbox.

Introduction

This is my first attempt at writing a class and at writing a Code Project article so I hope it will be of some use. I noticed I was using a lot of listbox saving/restoring in my applications so I decided to write a class for this. The class does not contain error handling but it should work fine. To use it just add the files to your project and include ListBoxSafe.h. There are (only) two functions you can use (simplicity):

void LoadList(CListBox &list, CString FileName, int MaxItems, int ItemLen);

and

void SaveList(CListBox &ListToFill, CString FileName, int MaxItems, int MaxItemLen);

list/ListToFill is the ListBox that you need to save or fill.
FileName is the name of the file from which you want to load or to which you want to save to.
MaxItems is the maximum amount of items to be saved or loaded.
ItemLen/MaxItemLen is the maximum length of a listbox item (should be the same if you save and load).

You can give MaxItems the value 0, and it will be 999 by default.
You can give MaxItemLen/ItemLen the value 0, and it will be 30 by default.

Example

CListBoxSafe::SaveList(m_lMyList,"test.dat",0,0);
CListBoxSafe::LoadList(m_lDataList,"data.txt",0,0);
