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);
