  • Deceptive MySQL Query

    - by jerebear
    So I don't consider myself a novice at MySQL but this one has me stumped: I have a message board and I want to pull a list of all the most recent posts grouped by the Thread ID. Here's the table: MB_Posts -ID -Thread_ID -Created_On (timestamp) -Creator_User (user_id) -Subject -Contents -Edited (timestamp) -Reported I've tried many different things to keep it simple but I would like help from the community on this one. Just to kick this out there...this one does not work as expected: SELECT * FROM MB_Posts GROUP BY Thread_ID ORDER BY ID DESC

  • Feedback on Optimizing C# NET Code Block

    - by Brett Powell
    I just spent quite a few hours reading up on TCP servers and my desired protocol I was trying to implement, and finally got everything working great. I noticed the code looks like absolute bollocks (is the the correct usage? Im not a brit) and would like some feedback on optimizing it, mostly for reuse and readability. The packet formats are always int, int, int, string, string. try { BinaryReader reader = new BinaryReader(clientStream); int packetsize = reader.ReadInt32(); int requestid = reader.ReadInt32(); int serverdata = reader.ReadInt32(); Console.WriteLine("Packet Size: {0} RequestID: {1} ServerData: {2}", packetsize, requestid, serverdata); List<byte> str = new List<byte>(); byte nextByte = reader.ReadByte(); while (nextByte != 0) { str.Add(nextByte); nextByte = reader.ReadByte(); } // Password Sent to be Authenticated string string1 = Encoding.UTF8.GetString(str.ToArray()); str.Clear(); nextByte = reader.ReadByte(); while (nextByte != 0) { str.Add(nextByte); nextByte = reader.ReadByte(); } // NULL string string string2 = Encoding.UTF8.GetString(str.ToArray()); Console.WriteLine("String1: {0} String2: {1}", string1, string2); // Reply to Authentication Request MemoryStream stream = new MemoryStream(); BinaryWriter writer = new BinaryWriter(stream); writer.Write((int)(1)); // Packet Size writer.Write((int)(requestid)); // Mirror RequestID if Authenticated, -1 if Failed byte[] buffer = stream.ToArray(); clientStream.Write(buffer, 0, buffer.Length); clientStream.Flush(); } I am going to be dealing with other packet types as well that are formatted the same (int/int/int/str/str), but different values. I could probably create a packet class, but this is a bit outside my scope of knowledge for how to apply it to this scenario. If it makes any difference, this is the Protocol I am implementing. http://developer.valvesoftware.com/wiki/Source_RCON_Protocol

  • how to remove empty tags in input xml

    - by SGB
    My java module gets a huge input xml from a mainframe. Unfortunately, the mainframe is unable to skip optional elements when it is not a leaf node, with the result that I get a LOT of empty tags in my input : So, <pre><code><SSN>111111111</SSN> <Employment> <Current> <Address> <line1/> <line2/> <line3/> <city/> <state/> <country/> </Address> <Phone> <phonenumber/> <countryCode/> </Phone> </Current> <Previous> <Address> <line1/> <line2/> <line3/> <city/> <state/> <country/> </Address> <Phone> <phonenumber/> <countryCode/> </Phone> </Previous> </Employment> <MaritalStatus>Single</MaritalStatus> </code></pre> should be <SSN>111111111</SSN> <MaritalStatus>Single</MaritalStatus> I use jaxb to unmarshall the input xml string that the mainframe sends it. Is there a clean/ easy way to remove all the empty group tags, or do I have to do this manuall in the code for each element. I have over 35 elements in my input xml, so I would love to it if jaxb itself had a way of doing this automatically? Thanks, SGB

  • How do I restrict foreign keys choices to related objects only in django

    - by Jeff Mc
    I have a two way foreign relation similar to the following class Parent(models.Model): name = models.CharField(max_length=255) favoritechild = models.ForeignKey("Child", blank=True, null=True) class Child(models.Model): name = models.CharField(max_length=255) myparent = models.ForeignKey(Parent) How do I restrict the choices for Parent.favoritechild to only children whose parent is itself? I tried class Parent(models.Model): name = models.CharField(max_length=255) favoritechild = models.ForeignKey("Child", blank=True, null=True, limit_choices_to = {"myparent": "self"}) but that causes the admin interface to not list any children.

    - by BillJeansk
    Hello, currently I have dual boot with 2 windows 7. (dont ask why, long story, I need them for each with different settings involving Audio Recording) I am very keen to install the new Ubuntu and get into a new OS, out of interest but I don't want to mess with my current 2 windows installations? If I install Ubuntu, will this simply add to my list of OS boot options when you set it, like I did when I install my 2nd Windows 7 Any comments or help would be great? Thanks Bill

  • How to configure bugzilla to not advance to next bug when updating?

    - by WilliamKF
    By default, when you apply changes to a Bugzilla entry, the web interface advances to the next bug in your list. I would like to disable this feature since it is almost never what I desire, planning to make further updates later. Further, I often update the wrong bug subsequently due to its changing the current bug without my noticing. How do I configure Bugzilla to not advance like this?

  • WPF MVVM Cancel Edit

    - by terkri
    How can I implement cancelation of editing an object using MVVM. For example: I have a list of customers. I choose one customer an click the button "Edit", a dialog window(DataContext is binded to CustomerViewModel) opens and I start editing customer's fields. And then I decide to cancel editing, but the fields of the customer have been already changed, so how can I return a customer to its previous state in MVVM?

  • extra white line under li items that have no border

    - by isabel018
    I have a problem with extra white lines showing up under my list items. It's not a border as I haven't set any borders, except the one under My Account, it's just to show that the white line is not a border. The one under it is -- a 4px border the same color as the background. This problem occurred after I had resolved a conflict between my Nivo Slider and the Woocommerce plugin on my WP site. I got both of them to work together, but then this other issue with the list cropped up. Any ideas as to what caused this and how to fix it? Here's my CSS if that helps: #header #navigation ul.nav > li.current_page_item > a { color: #D4145A;} #header #navigation ul.nav > li:hover a { border-width: 0px 0px 4px; border-style: none none solid; border-color: -moz-use-text-color -moz-use-text-color rgb(212, 20, 90); -moz-border-top-colors: none; -moz-border-right-colors: none; -moz-border-bottom-colors: none; -moz-border-left-colors: none; border-image: none; background: none repeat scroll 0% 0% rgb(212, 20, 90);} and the HTML for it too: <nav id="navigation" class="col-full parent" role="navigation"> <ul id="main-nav" class="nav fl parent"> <li class="page_item"></li> <li class="page_item page-item-11"></li> <li class="page_item page-item-12"></li> <li class="page_item page-item-13 parent"></li> <li class="page_item page-item-15 current_page_item parent"> <a href=""></a> <ul class="children"></ul></li> </ul> </nav> Help please! I'm at my wits' end! Thanks!

  • What kind of data belongs in a view model?

    - by Byron Sommardahl
    The name "view model" suggests that it models the data for the view. That much is obvious. What else can or should go in the view model? As an example, a view might display a list of items in a shopping cart, fields for customer's credit card info, and fields for customer's billing information. The view model might contain properties for all that OR it might only contain properties for the shopping cart items.
