Re: [python-win32] Getting the text out of a listbox from another process

[João Paulo Fernandes Farias]

Hi!

I've found the code bellow does what I want. Anyway to do it with
ctypes / win32 extensions?

<code>
#define WIN32_LEAN_AND_MEAN
#include <stdio.h>
#include <windows.h>
#include <commctrl.h>

int main(void) {
 HWND hwnd=FindWindow(NULL, "Stealing Program's Memory: ListView");
 HWND listview=FindWindowEx(hwnd, NULL, "SysListView32", NULL);

 int count=(int)SendMessage(listview, LVM_GETITEMCOUNT, 0, 0);
 int i;

 LVITEM lvi, *_lvi;
 char item[512], subitem[512];
 char *_item, *_subitem;
 unsigned long pid;
 HANDLE process;

 GetWindowThreadProcessId(listview, &pid);
 process=OpenProcess(PROCESS_VM_OPERATION|PROCESS_VM_READ|
                     PROCESS_VM_WRITE|PROCESS_QUERY_INFORMATION, FALSE, pid);

 _lvi=(LVITEM*)VirtualAllocEx(process, NULL, sizeof(LVITEM),
                              MEM_COMMIT, PAGE_READWRITE);
 _item=(char*)VirtualAllocEx(process, NULL, 512, MEM_COMMIT,
                             PAGE_READWRITE);
 _subitem=(char*)VirtualAllocEx(process, NULL, 512, MEM_COMMIT,
                                PAGE_READWRITE);

 lvi.cchTextMax=512;

 for(i=0; i<count; i++) {
  lvi.iSubItem=0;
  lvi.pszText=_item;
  WriteProcessMemory(process, _lvi, &lvi, sizeof(LVITEM), NULL);
  SendMessage(listview, LVM_GETITEMTEXT, (WPARAM)i, (LPARAM)_lvi);

  lvi.iSubItem=1;
  lvi.pszText=_subitem;
  WriteProcessMemory(process, _lvi, &lvi, sizeof(LVITEM), NULL);
  SendMessage(listview, LVM_GETITEMTEXT, (WPARAM)i, (LPARAM)_lvi);

  ReadProcessMemory(process, _item, item, 512, NULL);
  ReadProcessMemory(process, _subitem, subitem, 512, NULL);

  printf("%s - %s\n", item, subitem);
 }

 VirtualFreeEx(process, _lvi, 0, MEM_RELEASE);
 VirtualFreeEx(process, _item, 0, MEM_RELEASE);
 VirtualFreeEx(process, _subitem, 0, MEM_RELEASE);

 return 0;
}
