How to determine the message status (read/unread) in chat?

How to determine the message status (read/unread). Chat is realized with the XMPP protocol. XEP-0184 : Message Delivery Receipts supports notifying senders when their message has been delivered. You might be able to use that as a building block, as long as you don't expect existing clients to send these receipts -- the XEP is not widely-implemented today. I think you need to use the Displayed Chat Marker, per http://xmpp.org/extensions/xep-0333.html If you want to get the read receipts then instead of sending auto message delivery receipts, send it whenever user reads that message.

Infinite windows message loop

由 与世无争的帅哥 提交于 2019-12-02 21:17:26
问题 I have this message loop in my program: while (true) { if (PeekMessage(&msg, window, 0, 0, PM_REMOVE)) { if (msg.message == WM_QUIT) { MessageBox(NULL, L"Quit", L"", 0); break; } TranslateMessage(&msg); DispatchMessage(&msg); } else { Render(); } } This loop never ends.

django display message after POST form submit

由 我的未来我决定 提交于 2019-12-02 20:42:58
I have a page with a POST form, that have a action set to some url. i.e assume this page url is /form_url/ : .. The view in /submit_url/ take care of the form data. After this, I want to return the same page of the form with a success message. In the view that take care for the POST form, I use HttpResponseRedirect , in order to "clear" the form data from the browser. But in this way I can't display a message in the form page, unless I do something like: return HttpResponseRedirect("/form_url/?success=1") and then check for this parameter in the template. I don't like this way, since if the

How to use the default git commit message after resolving merge conflicts?

由 こ雲淡風輕ζ 提交于 2019-12-02 17:51:01
After doing a merge and resolving conflicts, is there an "easy" way to just accept the default generated commit message from the command line? One of our developers will resolve all the conflicts, and then do a git commit -m"Merge Commit" which replaces the generated commit message that listed all the conflict files. I would like to have a different flag that would just take the current file without modification. I know there is a -F or --file= option, but that requires knowing the file name all the time. Thank you Obviously the "right" answer here is to get your developer to follow correct

问题 In my asp site i'm trying to fetch user details from Active directory on page load. I like to show "loading.gif" image untill I get details. Could some help me as i'm new to jquery 回答1: Simple form of AJAX is the .get() method which should be enough for your needs.

Drawing box around message

由 混江龙づ霸主 提交于 2019-12-02 14:53:11
I'm working on this Python task that I can't figure out. It is the last of 3 functions and the first 2 were much easier to program then this one. The instructions are "Given a message that may contain multiple lines, utilize the split() function to identify the individual lines, and the format() function so that when printed, it draws a box around the message's lines, all centered. Box uses vertical bars & dashes on the sides (|, -), +'s in the corners (+), and there is always a column of spaces to the left and right of the widest line of the message." Some examples for what this function
