Why have you written the underscore in the casting by loading???

void CMPRSDlg::OnItemChangingMPRSLst(NMHDR *pNMHDR, LRESULT *pResult) 
{
//just at the beginning of the function
for (int i = 0; i < number_of_items; i++)
{
if (Help_array[i] == 1)

last_item = i;
Help_array[i] = 0;
break;           //When you find an old selected item break to have the index
}
last_item = -1;  //There was no selection before;
}
//your code to get the item that is changing

Help_array[index_of_changing_item] = 1; //Last line of your function, this will be the last selected item in the next OnChangingItem...
}

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

Help me to understand what I'm saying, and I'll explain it better to you
