Getting ListView Header Text

[Farhan Ali]

Asalam o Alaikum: I am getting problem while finding the ListView Header text through SendMessage() Does any body Knows Thanx

Is there any particular reason you are using SendMessage() instead of myListView.Columns[columnIndex].Text

Actually i am trying to get ListView Header text from other application. So i have to use SendMessage(); there are other functions like LVM_GETITEM ,i am in a search of this kind of function. Thanx

Here's a sample on how to do it (just copy / paste the code and build it) public const UInt32 LVM_FIRST = 0x1000; public const UInt32 LVM_GETCOLUMN = LVM_FIRST + 95; public const UInt32 LVCF_TEXT = 0x0004; [StructLayout(LayoutKind.Sequential, Pack=8, CharSet=CharSet.Auto)] public struct LVCOLUMN { public uint mask; public int fmt; public int cx; public IntPtr pszText; public int cchTextMax; public int iSubItem; public int iImage; public int iOrder; } [DllImport("User32", CharSet=CharSet.Auto)] public static extern IntPtr SendMessage(IntPtr hWnd, UInt32 msg, UInt32 wParam, ref LVCOLUMN lParam); private void button1_Click(object sender, System.EventArgs e) { int iTextSize = 255; IntPtr pText = Marshal.AllocHGlobal(iTextSize); LVCOLUMN lCol = new LVCOLUMN(); lCol.mask = LVCF_TEXT; lCol.cchTextMax = iTextSize - 1; lCol.pszText = pText; uint nIndex = 0; SendMessage(listView1.Handle, LVM_GETCOLUMN, nIndex, ref lCol); System.Diagnostics.Trace.WriteLine(Marshal.PtrToStringAuto(pText)); Marshal.FreeHGlobal(pText); } } } I hope that not naming my controls properly will not bother you :) The demo uses list view on the same form, but I assume you already know how to get the handle of the listview, and replace it in the code above.
