hi,

im trying to add stuff to a listbox in a dialog called by my CDocument class

ie.

CODE
CMyDocument::DoSomeStuff()
{
CMyDialog dlg;
dlg.listbox.addString("whatever");

********

dlg.listbox.doModal();
}


do i need to add something at the ******* to refresh my listbox because at the moment it is appearing downright empty. i created it by making a dialog in the resource editor of vc++ .NET 2003 and then using add class wizard, and add member wizard to make the listbox an accessable control.

thanks for your time!

try
List->InsertItem (&item);
List->InsertColumn (x,fd->name,LVCFMT_LEFT,strlen(fd->name)*6+16,1);

CODE


  List->DeleteAllItems( ); // 删除当前所有item

  res = mysql_store_result( myData );
  for ( int x = 0; fd = mysql_fetch_field( res ); x++ )
  {
   List->InsertColumn (x,fd->name,LVCFMT_LEFT,strlen(fd->name)*6+16,1);//获取column
  }
  LV_ITEM    item;
  item.mask = LVIF_TEXT;
  item.iItem = -1;
  while ( row = mysql_fetch_row( res ) )
  {
   j = mysql_num_fields( res );
   item.iItem+=1;
   for (int k = 0; k < j; k++ )
   {
    item.iSubItem = k;
    item.pszText=row[k];
    List->InsertItem (&item);
    List->SetItem (&item);
   }
  }

hmmmm.... thanks but i think that is for mysql....

im using mfc in visual c++ .NET, so it isn't much of a help.

thanks for your time anyway.

hi again, i finally got stuff sorted out. I was after the mfc dialog UpdateData(FALSE) method after the CListBox.AddString() method but i was putting UpdateData(FALSE) in the Dialog's OnCreate() method. because the control wasn't created yet, the listbox control could not be refreshed (i think).

thanks for your help!
