Hi,

    I would  like to display all listview items in one row with scroll bar below it –  instead of multiple rows and scroll bar on the right.  Someone told me that I can achieve it using LVM_SETITEMPOSITION message.

    According  to my knowledge code below should set position for each item added to listView  control. There are two ways of doing it - we can use Messagewindow.SendMessage from Microsoft.WindowsCE.Forms or use DllImport and SendMessage.   For  some unknown reason code is not working as expected and control displays items  in multiple rows.    

    Could  someone please help me ?

    

    public static IntPtr MakeLParam(int  wLow, int wHigh)

            {

                return (IntPtr)(((short)wHigh << 16) | (wLow & 0xffff));

            }

    

            

            [DllImport("coredll.dll",  SetLastError = true)]

            public static extern IntPtr  SendMessage(IntPtr hWnd, uint Msg, IntPtr  wParam, IntPtr lParam);

    

            const uint LVM_SETITEMPOSITION = 0x1000 + 15;

    

            private void function()

            {

                

                ImageList imageList = new  ImageList();

                listView.View  = System.Windows.Forms.View.LargeIcon;

                

                

    

                try

                {

                    

                    int x = 0;

                    foreach ()

                    {

                      

                        ListViewItem item = new  ListViewItem(desc);

                        

                        

                        //magic

                        int index = listView.Items.Count;

    

                        

    

                        IntPtr wparam = (IntPtr)index;

                        IntPtr lparam = MakeLParam(x, 0);

    

                        Message mes = Message.Create(listView.Handle,  0x1000 + 15, wparam, lparam);

                        Messagewindow.SendMessage(ref  mes);

    

    

                        

    

    

    

    

                        //old

                        //IntPtr listH = listView.Handle;

                        //int index = listView.Items.Count;

    

                        

                        //int y = 0;

    

                        //int t = SendMessage(listH, LVM_SETITEMPOSITION, index,  m);

                        //IntPtr t = SendMessage(listView.Handle,  LVM_SETITEMPOSITION, (IntPtr)index, MakeLParam(x, y));

    

                        x  += 20;

    

                         listView.Items.Add(item);

                        

                    }

                    

                     listView.LargeImageList = imageList;

                    

                }

                catch (Exception  ex)

                {

                    

                }

            }
