    <p>Well, it turns out I was wrong on several points there. However it is possible to do by allocating memory inside the target process, constructing the required struct (LVITEM) there, sending the message and reading back the result from the buffer allocated in said process.</p> <p>For the sake of completeness, I attach a code example for reading SysListView32 items from a foreign process, given a window handle of the control.</p> <pre><code>from win32con import PAGE_READWRITE, MEM_COMMIT, MEM_RESERVE, MEM_RELEASE,\ PROCESS_ALL_ACCESS from commctrl import LVM_GETITEMTEXT, LVM_GETITEMCOUNT import struct import ctypes import win32api import win32gui GetWindowThreadProcessId = ctypes.windll.user32.GetWindowThreadProcessId VirtualAllocEx = ctypes.windll.kernel32.VirtualAllocEx VirtualFreeEx = ctypes.windll.kernel32.VirtualFreeEx OpenProcess = ctypes.windll.kernel32.OpenProcess WriteProcessMemory = ctypes.windll.kernel32.WriteProcessMemory ReadProcessMemory = ctypes.windll.kernel32.ReadProcessMemory memcpy = ctypes.cdll.msvcrt.memcpy def readListViewItems(hwnd, column_index=0): # Allocate virtual memory inside target process pid = ctypes.create_string_buffer(4) p_pid = ctypes.addressof(pid) GetWindowThreadProcessId(hwnd, p_pid) # process owning the given hwnd hProcHnd = OpenProcess(PROCESS_ALL_ACCESS, False, struct.unpack("i",pid)[0]) pLVI = VirtualAllocEx(hProcHnd, 0, 4096, MEM_RESERVE|MEM_COMMIT, PAGE_READWRITE) pBuffer = VirtualAllocEx(hProcHnd, 0, 4096, MEM_RESERVE|MEM_COMMIT, PAGE_READWRITE) # Prepare an LVITEM record and write it to target process memory lvitem_str = struct.pack('iiiiiiiii', *[0,0,column_index,0,0,pBuffer,4096,0,0]) lvitem_buffer = ctypes.create_string_buffer(lvitem_str) copied = ctypes.create_string_buffer(4) p_copied = ctypes.addressof(copied) WriteProcessMemory(hProcHnd, pLVI, ctypes.addressof(lvitem_buffer), ctypes.sizeof(lvitem_buffer), p_copied) # iterate items in the SysListView32 control num_items = win32gui.SendMessage(hwnd, LVM_GETITEMCOUNT) item_texts = [] for item_index in range(num_items): win32gui.SendMessage(hwnd, LVM_GETITEMTEXT, item_index, pLVI) target_buff = ctypes.create_string_buffer(4096) ReadProcessMemory(hProcHnd, pBuffer, ctypes.addressof(target_buff), 4096, p_copied) item_texts.append(target_buff.value) VirtualFreeEx(hProcHnd, pBuffer, 0, MEM_RELEASE) VirtualFreeEx(hProcHnd, pLVI, 0, MEM_RELEASE) win32api.CloseHandle(hProcHnd) return item_texts </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
