[英]Get listview from third party application
我正在嘗試從第三方應用程序獲取列表視圖,這是我試圖完成此操作的方式
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, StringBuilder lParam);
const int LVM_GETITEMCOUNT = 0x018B;
const int LVM_GETITEMTEXT = 0x0189;
// Get ListBox contents hwnd
private List<string> GetListViewContents(IntPtr listviewHwnd)
{
int cnt = (int)SendMessage(listviewHwnd, LVM_GETITEMCOUNT, IntPtr.Zero, null);
List<string> listViewContents = new List<string>();
for (int i = 0; i < cnt; i++)
{
StringBuilder sb = new StringBuilder(256);
IntPtr getText = SendMessage(listviewHwnd, LVM_GETITEMTEXT, (IntPtr)i, sb);
listViewContents.Add(sb.ToString());
}
return listViewContents;
}
然后,我使用UISpy獲取應用程序上listview屬性的句柄,並使用以下代碼填充我的應用程序列表框:
IntPtr ks = new IntPtr(0x00040FA8); // temp handle for the 3rd party listview
listBox1.DataSource = GetListViewContents(ks);
沒有返回數據,這是什么問題?
