There's nothing special to it. You can use normal file handling routines. Just like how you write a file to your hard disk.

Do not follow Monty's advise he is confused .
Well you are already half way thro to reach what you want .
You said you write the last selected string in a section called Default in an .ini file . So why not you just read the same Default entry when app starts and compare it with combobox items and then you SetSel(item no) . I feel you mean setting focus by "blue color"

Ya..u mean...I will compare with if condition n then use selcur method. ( i want to focus or highligh last item..For example when we select any application then it will show us in blue or any color.. that what i want.. ie just only indicate me this section i selected last time.. )
Setcursel is appropriate method or not??

Hi
Read the Default section of .ini file and get the string in CString or LPCTSTR = lpszStr;
Now implement the following in your OnInitDialog()
int lastselection = m_combo.FindString(0,lpszStr);
m_combo.SetCurSel(lastselection);

Hi
1) Read your ini file and load the default string in CString str or LPCTSTR str;
2) implement the following in your OnInitDialog
int lastselection = m_combo.FindString(0,lpszStr);
m_combo.SetCurSel(lastselection);

Well you will have to Owner draw the combobox yourself, lots of articles on owner draw on CP use search.
Then it comes to be that the soothing light at the end of your tunnel
Is just a freight train coming your way

After you have added all the items to the combobox, call SelectString() with the one you want selected.

In caseof VS2005, you need to dilog class from class view right click on its properties, and then add/edit required message/overidables.

hey guys,
I was wondering what the most efficient way of finding the number of occurences in a list is.
Say I have a list....
struct data{
int number;
int occurences;
};
data list[7];
list[0].number = 5;
list[1].number = 6;
list[2].number = 6;
list[3].number = 8;
list[4].number = 9;
list[5].number = 9;
list[6].number = 9;
how would i sort in such a way that I eliminate the numbers that occur more than once like this,
list[0].number = 5;
list[1].number = 6;
list[2].number = 8;
list[3].number = 9;
and saves the number of occurence for each number
list[0].occurences = 1;
list[1].occurences = 2;
list[2].occurences = 1;
list[3].occurences = 3;
I thought of every possible way,
I can do it for numbers that appear twice but three times, i duno how to deal with it.....
Someone please help me out

Why did you use the name 'list' for a variable which is an array ?
Could you post your current algorithm to correct it ?
