Get ListView items from other windows

Question

I'm doing some project on c#. I need to get i item from ListView window, handle of it I got by doing something like this

IntPtr par_hWnd = API.FindWindow(null, "Form1");
IntPtr child1 = API.FindWindowEx(par_hWnd, (IntPtr)0, null, null);

API is my static class with lots of dllimports from "user32.dll" I am able to get count of items in this ListView:

IntPtr count = API.SendMessage(child1, API.LVM_GETITEMCOUNT, 0, 0);

Now i need to get the text of item, but the result somehow must be placed in the LVITEM Structure, I don't know how to call SendMessage correctly, and how to implement LVITEM in c#. Can't find examples for c#. Any help?

Answer 1

I found a C# wrapper for WinAPIs that seems to provide access to the contents of an LV from any window.
ManagedWinapi

using ManagedWinapi.Windows;
using System;

namespace TestApp
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create a SystemWindow object from the HWND of the ListView
            SystemWindow lvWindow = new SystemWindow((IntPtr)0x6d1d38);

            // Create a ListView object from the SystemWindow object
            var lv = SystemListView.FromSystemWindow(lvWindow);

            // Read text from a row
            var text = lv[0].Title;
        }
    }
}

Also, I have also forked mwapi here and am trying to add some new functionality - Mainly centred around colouring ListView rows, but also adding some missing p/invokes etc.
