• Find the “DlgGroupChat Window Class” window handler, using FindWindowW.
• Find the “SysHeader32” window handler in the sublist. Use EnumChildWindows.
• Send a LVM_GETITEMCOUNT message using the SendMessage function to get the number of users in the room.
• Send LVM_GETITEMTEXTA messages to each user metric using the SendMessage function to get the room member's nickname.
LVM_GETITEMCOUNT and LVM_GETITEMTEXT are messages used to interact with ListView controls in Windows.
- LVM_GETITEMCOUNT: This message is used to get the number of items in a ListView. When sending this message to a ListView, it will return the number of items currently in that ListView.
- LVM_GETITEMTEXT: This message is used to get the text of an item in a ListView. When sending this message to a ListView, you need to provide the index of the item for which you want to get the text and a buffer to store the text. After sending the message, the buffer will contain the text of that item.
In the case of Paltalk, we use the LVM_GETITEMCOUNT message to get the number of users in the room and the LVM_GETITEMTEXT message to get the nickname of each user.

Nếu bạn đã sử dụng LVM_GETITEMTEXTW nhưng vẫn không lấy được tên người dùng chứa ký tự tiếng Việt, có thể có một số vấn đề khác xảy ra. Bạn có thể kiểm tra lại các bước sau:
- Đảm bảo rằng bạn đã cung cấp đúng con trỏ LVITEMW cho hàm SendMessage khi gửi tin nhắn LVM_GETITEMTEXTW.
- Đảm bảo rằng bạn đã cấp phát đủ bộ nhớ cho trường pszText của cấu trúc LVITEMW và đặt giá trị cho trường cchTextMax bằng kích thước của bộ nhớ đã cấp phát.
- Đảm bảo rằng bạn đang sử dụng các hàm xử lý chuỗi Unicode để xử lý kết quả trả về từ LVM_GETITEMTEXTW.
Nếu bạn đã kiểm tra lại các bước nhưng vẫn không lấy được tên người dùng chứa ký tự tiếng Việt, có thể có một số nguyên nhân khác gây ra vấn đề này. Để giúp tôi xác định nguyên nhân của vấn đề, bạn có thể cung cấp thêm thông tin về mã nguồn của bạn, cụ thể là phần liên quan đến việc gửi tin nhắn LVM_GETITEMTEXTW và xử lý kết quả trả về. Bạn cũng có thể cung cấp thông tin về phiên bản của Paltalk mà bạn đang sử dụng và hệ điều hành của máy tính của bạn.

- Get the list of users in the room: Retrieve the nicknames of users currently in the room, using the SysHeader32 control and LVM_GETITEMTEXTA as suggested by the Paltalk team.
- Check microphone status: Use the WM_USER + 1 message with the member index to check the "asking for microphone" flag, and use LVM_GETITEMW to check mic status (where LVITEMW::iImage equals 10 if the mic is on).
- Fix issues with existing code: Update the code to use the correct window class (Qt5150QWindowIcon instead of DlgGroupChat Window Class, based on prior context) and ensure it works with the latest Paltalk build (1.29.0.89332).
- Support Unicode: Ensure proper handling of nicknames with Vietnamese text and emojis (e.g., 😊👍), as Paltalk uses Segoe UI font with emoji support.
- Incorporate prior functionality: Retain the ability to read chat messages, filter system messages (join/leave/muted), and list rooms reliably, as implemented in the previous code.
- Provide English comments: Since the user is American, all comments, console output, and log messages should be in English, as done in the previous response.
The Paltalk team's response indicates that to get member names and mic status:
- Find the SysHeader32 control (likely a typo; they meant SysListView32, as SysHeader32 is typically the header of a ListView, not the list itself).
- Use LVM_GETITEMCOUNT to get the number of users.
- Use LVM_GETITEMTEXTA to get nicknames.
- Use LVM_GETITEMW to check mic status (iImage == 10 for mic on).
- Use WM_USER + 1 with the member index to check the microphone queue flag.
However, the user's complaint suggests that previous attempts to get member names (likely using SysListView32) failed, possibly due to incorrect control identification, outdated window classes, or issues with Unicode handling. I’ll update the previous code to:
- Use SysListView32 (instead of SysHeader32) for user lists, as it’s the standard ListView control.
- Implement LVM_GETITEMTEXTA and LVM_GETITEMW for nicknames and mic status.
- Add WM_USER + 1 for the microphone queue flag.
- Retain pywinauto as a fallback for reliability.
- Use Qt5150QWindowIcon for room windows (consistent with prior context).
- Keep all messages and comments in English.
Below is the updated Python code that addresses the user’s request and incorporates the Paltalk team’s guidance.

- User List: Compare the nicknames from the code with the user list in Paltalk’s UI.
- Mic Status: Check if users with “Mic On” match those currently speaking in the room.
- Microphone Queue: Verify that users with “Asking for Mic” are in the mic queue.
- System Messages: Ensure messages like “[User] has joined the room” or “[User] has been muted” appear in the system messages list.
- Unicode: Confirm that Vietnamese text (e.g., “Xin chào”) and emojis (😊👍) display correctly.
- Check the Log:
- Open paltalk_log_2025-08-21.log and look for errors like “User list handle not initialized” or “Error retrieving user list.”
- Confirm entries like “Found user list control: SysListView32” or “Found X users.”
- Use Spy++:
- Open Paltalk, join Inner peace ♥, and use Spy++ to verify:
- Room window: Class must be Qt5150QWindowIcon.
- Chat display control: Class is RichEdit20W, RichEdit32, RichEdit50W, or ui::controls::EmojiTextEdit.
- User list control: Class is SysListView32 or ui::controls::UserList.
- If classes differ, update the code:
pythonif class_name in ["SysListView32", "ui::controls::UserList", "NewClass"]:
- Open Paltalk, join Inner peace ♥, and use Spy++ to verify:
- Manual Testing:
- In Paltalk, observe the user list, send messages (e.g., “Xin chào 😊”), and check mic/queue status.
- If no users are retrieved, ensure Paltalk build 1.29.0.89332 is installed.
- Share Debug Info:
- Extract paltalk_log_2025-08-21.log.
- Capture Spy++ screenshots of the room window and user list control.
- Describe issues (e.g., “No users retrieved” or “Mic status incorrect”).
- List rooms: ~50-100ms.
- Read messages: ~50-100ms (Win32), ~100-200ms (pywinauto).
- Get user list: ~100-200ms (Win32), ~200-300ms (pywinauto).
- Mic status/queue: ~1-5ms per user.
- Unicode: LVM_GETITEMTEXTA may have limitations with non-ASCII characters; pywinauto is more reliable for Vietnamese/emojis.
- Mic Status Limitation: pywinauto cannot retrieve mic status or queue flags; use win32gui for those.
- Paltalk Build: Ensure build 1.29.0.89332 is installed, as older versions may not support WM_USER + 1 or LVM_GETITEMW.
