Rvt获取窗体句柄

如果有，关闭对话框句柄

IntPtr ptr = FindWindow(null, "梁串编号索引"); if (ptr != null && ptr != IntPtr.Zero) {     int WM_CLOSE = 0x0010;     SendMessage(ptr, WM_CLOSE, 0, 0); }

win32获取界面信息，发送信息

[DllImport("user32.dll", EntryPoint = "FindWindow")] internal static extern IntPtr FindWindow(string ClassName, string WindowNamw);  [DllImport("User32.dll", EntryPoint = "SendMessage")] private static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);
