syslistview32

问题 I try to spy an syslistview32 element. Reading the content is working quite well but I'm not able to get the text of the column headers. This is "my" code (I don't want to adorn myself with borrowed plumes - most of the code is from https://konradn.wordpress.com/2012/02/21/read-listviewitem-content-from-another-process/): [System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential)] struct LV_COLUMN { public System.Int32 mask; public System.Int32 fmt;

问题 I have a SysListView32 that should potentially host millions of rows, and three columns of text A, B, C each < 256 characters. Let's say column B has many many repetitions (example: column A is filename, column B is path, and each row is a file of the filesystem), and has only 100k different values (instead of several millions). Is it possible to avoid duplication in RAM of content of column B of the ListView GUI element? Can we fill a ListView with only pointers to arrays elements (taken

问题 here is my code : public static string ReadListViewItem(IntPtr lstview, int item) { const int dwBufferSize = 1024; int dwProcessID; LV_ITEM lvItem; string retval; bool bSuccess; IntPtr hProcess = IntPtr.Zero; IntPtr lpRemoteBuffer = IntPtr.Zero; IntPtr lpLocalBuffer = IntPtr.Zero; IntPtr threadId = IntPtr.Zero; try { lvItem = new LV_ITEM(); lpLocalBuffer = Marshal.AllocHGlobal(dwBufferSize); // Get the process id owning the window threadId = GetWindowThreadProcessId(lstview, out dwProcessID);

问题 I have an application with a ListView ('SysListView32') control, from which I would like to extract data. The control has 4 columns, only textual data. I have been playing around the following lines (found online somewhere): VALUE_LENGTH = 256 bufferlength_int=struct.pack('i', VALUE_LENGTH) count = win32gui.SendMessage(TargetHwnd, commctrl.LVM_GETITEMCOUNT, 0, 0) for ItemIndex in range(count): valuebuffer = array.array('c',bufferlength_int + " " * (VALUE_LENGTH - len(bufferlength_int)))
