How to Add String in MultiColumn ListBox

Pankaj Jain

Hi All I m working on a ATL Project. I have to add string in a multi column List box using SendDlgItemMessage() but I dont get any idea about that. I m using it like this SendDlgItemMessage(IDC_LIST1, LB_INSERTSTRING, (WPARAM) 0, (LPARAM)"Hi"); SendDlgItemMessage(IDC_LIST1, LB_INSERTSTRING, (WPARAM) 1, (LPARAM)"All"); But it is not working. I want to Add "Hi" in one column and "All" other. If u have any Idea Please suggest me Thanks & Regards Pankaj Jain

WPARAM value refers to item index, not column index.

For that you need to answer questions asked. I asked, what do you mean by not working ?

Same as you written in in your original post. I think you mistaken multicolumn with number of columns as in list box. In case of list box, multi column means, there will be no vertical scrolling as number of string keeps increasing. Instead, string will be added to next column and so on, and horizontal scroll bar will appear. I hope this clear your doubts.

A MultiColumn ListBox doesn't give that functionality - you want a ListView instead. To add text to a ListView in the way you want, use something like:

// Set up the columns
LVCOLUMN col = {0};
SendDlgItemMessage(IDC_LIST2, LVM_INSERTCOLUMN, 0, (LPARAM)&col);
col.iSubItem = 1;
SendDlgItemMessage(IDC_LIST2, LVM_INSERTCOLUMN, 1, (LPARAM)&col);

LVITEM item = {0};
item.mask = LVIF_TEXT;
item.iSubItem = 0;
item.pszText = "Hi";
int itemIndex = (int)SendDlgItemMessage(IDC_LIST2, LVM_INSERTITEM, 0, (LPARAM)&item);
item.iSubItem = 1;
item.pszText = "All";
SendDlgItemMessage(IDC_LIST2, LVM_SETITEMTEXT, itemIndex, (LPARAM)&item);

SendDlgItemMessage(IDC_LIST2, LVM_SETCOLUMNWIDTH, 0, LVSCW_AUTOSIZE);
SendDlgItemMessage(IDC_LIST2, LVM_SETCOLUMNWIDTH, 1, LVSCW_AUTOSIZE);

[Updated to correct code, add column sizing]
