  • GLib Hash Table - Pointer

    - by Mike
    I'm trying to increment the value of some specific key if it was found. For some reason I keep getting the (pointer) address when I dump all keys:values from the hash table. Output a: 153654132 // should be 5 b: 1 c: 153654276 // should be 3 d: 1 e: 1 f: 153654420 // should be 3 int proc() { struct st stu; gpointer ok, ov; //... some non-related code here if(!g_hash_table_lookup_extended(table, key, &ok, &ov)){ stu.my_int = g_malloc(sizeof(guint)); *(stu.my_int) = 0; g_hash_table_insert(table, g_strdup(key), GINT_TO_POINTER(1)); }else{ stu.my_int = g_malloc(sizeof(guint)); *(stu.my_int)++; g_hash_table_insert(table, g_strdup(key), stu.my_int); } } Any ideas will be appreciate it.

  • Syncing two separate structures to the same master data

    - by Mike Burton
    I've got multiple structures to maintain in my application. All link to the same records, and one of them could be considered the "master" in that it reflects actual relationships held in files on disk. The other structures are used to "call out" elements of the main design for purchase and work orders. I'm struggling to come up with a pattern that deals appropriately with changes to the master data. As an example, the following trees might refer to the same data: A |_ B |_ C |_ D |_ E |_ B |_ C |_ D A |_ B E C |_ D A |_ B C D E These secondary structures follow internal rules, but their overall structure is usually user-determined. In all cases (including the master), any element can be used in multiple locations and in multiple trees. When I add a child to any element in the tree, I want to either automatically build the secondary structure for each instance of the "master" element or at least advertise the situation to the user and allow them to manually generate the data required for the secondary trees. Is there any pattern which might apply to this situation? I've been treating it as a view problem, but it turns out to be more complicated than that when you look at the initial generation of the data.

  • C# text creation issue

    - by Mike
    This is whats going on. I have a huge text file that is suppose to be 1 line per entry. The issue is sometimes the line is broken with a new line. I edit this entire file and wherever the file doesn't begin with ("\"A) i need to append the current line to the previous line ( replacing \n with " "). Everything I come up with keeps appending the line to a new line. Any help is appricated... CODE: public void step1a() { string begins = ("\"A"); string betaFilePath = @"C:\ext.txt"; string[] lines = File.ReadAllLines(betaFilePath); foreach (string line in lines) { if (line.StartsWith(begins)) { File.AppendAllText(@"C:\xt2.txt",line); File.AppendAllText(@"C:\xt2.txt", "\n"); } else { string line2 = line.Replace(Environment.NewLine, " "); File.AppendAllText(@"C:\xt2.txt",line2); } } } Example: Orig: "\"A"Hero|apple|orange|for the fun of this "\"A"Hero|apple|mango|lots of fun always "\"A"Her|apple|fruit|no pain is the way "\"A"Hero|love|stackoverflowpeople|more fun Resulting: "\"A"Hero|apple|orange|for the fun of this "\"A"Hero|apple|mango|lots of fun always "\"A"Her|apple|fruit|no pain is the way "\"A"Hero|love|stackoverflowpeople|more fun

  • forwarding a notification to another class

    - by Mike
    I am using this method - (void)keyboardWillShow:(NSNotification *)notification that is triggered when the keyboard shows. When this method is triggered, it receives a notification that contains several parameters about the keyboard, as the animation duration, animation curve and frame. I need to forward this notification and all its parameters to another class. So, I've tried to do this inside keyboardWillShow: [[NSNotificationCenter defaultCenter] postNotificationName:@"doSomething" object:notification userInfo:nil]; the doSomething notification runs doSomething method on another class, and it has this form: - (void) doSomething:(NSNotification *)notification { but when I try to read the notification values on this other class, using, for example, myRect = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue]; I obtain zero for all values. The notification is losing its parameters and not being forwarded. How can I do that? thanks.

  • foreach loop from multiple arrays c#

    - by Mike
    This should be a simple question. All I want to know is if there is a better way of coding this. I want to do a foreach loop for every array, without having to redeclare the foreach loop. Is there a way c# projects this? I was thinking of putting this in a Collection...? Please, critique my code. foreach (TextBox tb in vert) { if (tb.Text == box.Text) conflicts.Add(tb); } foreach (TextBox tb in hort) { if (tb.Text == box.Text) conflicts.Add(tb); } foreach (TextBox tb in cube) { if (tb.Text == box.Text) conflicts.Add(tb); }

  • resource-ref at application scope in EJB 2.1 Project

    - by Mike Deck
    Is it possible to define resource references that are applicable to all EJBs in an application? Currently I have an ejb-jar.xml that looks something like this: <ejb-jar> <enterprise-beans> <session id="foo"> <!-- snip --> <resource-ref> <res-ref-name>jdbc/myDatasource</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> </session> <session id="bar"> <!-- snip --> <resource-ref> <res-ref-name>jdbc/myDatasource</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> </session> </enterprise-beans> </ejb-jar> You'll notice that both EJBs have the same resource-ref defined for both of them. Is there a way to factor this duplication out within a J2EE 1.4 application? Ideally I should be able to define the jdbc/myDatasource resource once within the application and have anything running inside that container be able to access it by doing a JNDI lookup for "java:comp/env/jdbc/myDatasource". Is there any way to accomplish this?

  • Some special characters defined in "ISO-8859-1" can't be shown when encoding with "UTF-8"

    - by Mike.Huang
    I need to get a string from URL request of brower, and then create a text image by requested text. I know the default encoding of the Java net transmission is "ISO-8859-1", it can works normally with all characters what defined in "ISO-8859-1". But when I request a multi-byte Unicode character (e.g. chinese or something like ¤?), then I need to decode it by "UTF-8" from "ISO-8859-1". My codes like: String reslut = new String(requestString.getBytes("ISO-8859-1"), "UTF-8"); Everything is fine, but I found some characters in ISO-8859-1 are not been shown now, which characters are 0x80 - 0xFF(defined in" ISO-8859-1"), i.e. the characters after 0x80 (in "ISO-8859-1") not been shown when converted to "UTF-8" from "ISO-8859-1". Any other method can solve this query?

  • IList<Item> Collection Class accessing database

    - by Mike
    Hi, I have a database with Users. Users have Items. These Items can change actively. How do you access the items in a collection type format? For the user, I fill all the user properties at the time of instantiation. If I load the user's items at the time of the instantiation, and the items change, they will have old data. I was thinking, maybe I need an ItemCollection class and have that a field/property apart of the user class, that way to traverse all the user's items I could use a foreach loop. So, my question is, what is the best practice/best way of accessing the items from a database using some sort of collection? On accessing the particular Item, it needs to get the latest database information, and when the user does do a foreach loop, the latest item information must be available. I.e. What I'm trying to do Console.WriteLine(User.Items[3].ID); returns 5. //this updates the item information and saves it to the database. User.Items[3].ID = 13; //Add a new item to the database. User.Items.Add(new Item { id = 17}); foreach (Item item in User.Items) { //this would traverse all items in the database. //not some cached copy at the time of instantiation of the user. }

  • Converting a year from 4 digit to 2 digit and back again in C#

    - by Mike Wills
    My credit card processor requires I send a two-digit year from the credit card expiration date. Here is how I a currently processing: I put a DropDownList of the 4-digit year on the page. I validate the expiration date in a DateTime field to be sure that the expiration date being passed to the CC processor isn't expired. I send a two-digit year to the CC processor (as required). I do this via a substring of the value from the year DDL. Is there a method out there to convert a four-digit year to a two-digit year. I am not seeing anything on the DateTime object. Or should I just keep processing it as I am?

  • C# switch: case not falling through to other cases limitation

    - by Mike Fielden
    This question is kind of an add-on to this question In C#, a switch case cannot fall through to other cases, this causes a compilation error. In this case I am just adding some number to the month total for the selected month and each subsequent month thereafter. (simple example, not meant to be real) switch (month) { case 0: add something to month totals case 1: add something to month totals case 2: add something to month totals default: break; } Is there a logical alternative to this in C# without having to write out a ton of if statements? if (month <= 0) add something to month if (month <= 1) add something to month if (month <= 2) add something to month .... etc

  • Website Sitemaps and <priority>, is it working?

    - by Mike Gleason jr Couturier
    Hi, My "Privacy Policy" page is seen more important by Google than other really more important pages on my website. I'm currently creating a script to generate a sitemap, should I bother with the priority? How do you effectively assign priorities to pages? I consider one of my page important but the page have less content than another one less important to my eyes... but maybe Google bot will see it the other way around. If my degree of "importantness" differs from the one of Google, will I get penalized on the ranking for a particular page? Thank you for sharing your black art with us :P

  • Are there any libraries to allow Python or Ruby to get info from SVN?

    - by Mike Trpcic
    I'm looking for plugins that will allow my codebase to interact with, browse, and poll an SVN server for information about a repository. Trac can do this, but I was hoping there was an easy-to-use library available to accomplish the task, rather than trolling through the Trac codebase. Googling for this returns mostly vague results about storing your code in and SVN repository, which is far from what I'm looking for.

  • IE is ignoring Z-Index on positioned elements

    - by Mike
    IE yet again is proving to be the bane of my existence. The top of a site I'm working on has a horizontal menu, an item of which triggers a pure-CSS menu that is positioned absolute within the parent menu DIV (positioned relative). This places the menu perfectly in both IE and the W3C compliant browsers. The problem arises when I have more positioned elements further down on the page. These are also positioned relative, because there is data inside them that needs to be positioned absolute... again, this displays properly in all browsers I've tested it on. The problem is, that then the top menu is opened, part is obscured by the positioned elements further down the page - in effect, it's positioned BELOW these elements even though there are z-index properties defined on all. (in both the CSS file and inline). The only way to get IE to display this properly is to place the actual HTML for the menu at the bottom of the page, below (in DOM terms) the positioned elements elsewhere on the page. I would only do this as an absolute last resort. All Elements are the same type (div). Here is the relevant HTML: <div id='menu'> <div id='cat_menu' style='display:none;z-index:10000;'> <table cellspacing='0' cellpadding='0' class='brmenu' width='100%'> [data] </table> </div> <div class='product_new' style='z-index:20;'>[data]</div> <div class='product_listing' style='background-color:#FFFFFF;'>[data]</div> And the relevant CSS: div#menu { height: 26px; padding: 0; position: relative; } div#cat_menu { position: absolute; top: 25px; left: 115px; width: 300px; z-index: 1000; } div.product_new { background-image: url("/images/sp_images.png"); background-position: 0 -108px; background-repeat: no-repeat; padding 0px; height: 40px; font-size: 9pt; margin-top: 5px; position: relative; z-index: 20; }

  • Android ScrollView jumps around when resized

    - by Mike
    I have a ScrollView that contains an number of other views (TextViews, ImageViews, etc.). The ScrollView is taller than the screen. I have an AsyncTask that updates the children of the ScrollView based on an http response. I've discovered an interesting behavior that I can't figure out how to work around. If I set any of the children's visibilities to View.INVISIBLE as part of the AsyncTask.onPostExecute(), everything works fine. However, if I set any of the children's visibilities to View.GONE, the ScrollView jumps down from the top when onPostExecute() is called. Exactly how far seems to vary. I'm guessing that re-laying out the ScrollView is causing it to scroll away from the top for some reason. So the question is: is there a way to either prevent or work around this behavior? PS. Using ScrollView.jump(FOCUS_UP) as a workaround isn't ideal since that'll force the user to the top even if they had intended to scroll down. EDIT: Actually, I was wrong. The problem wasn't with a child view being marked gone, the problem was with a sibling view being marked gone and the ScrollView getting resized. My ScrollView is inside a LinearLayout that also contains a Button. When the button is set to GONE, the ScrollView gets resized to take up the available space, causing it to scroll away from the top. Different cause, still looking for a workaround though if possible.

  • T4MVC adding current page controller to action link

    - by Mike Flynn
    I have the following ActionLink that sits in the home page on the register controller (Index.cshtml) @Html.ActionLink("terms of service", Url.Action(MVC.Home.Terms()), null, new { target="_blank" }) Generating the following URL. Why is "register" being added to it? It's as if the link within the Register page which has it's own controller is preappending the register controller to any link in that view? http://localhost/register/terms-of-service routes.MapRoute( "Terms", "terms-of-service", new { controller = "Home", action = "Terms" } ); public partial class HomeController : SiteController { public virtual ActionResult Terms() { return View(new SiteViewModel()); }

  • What do I use when a cron job isn't enough? (php)

    - by mike
    I'm trying to figure out the most efficient way to running a pretty hefty PHP task thousands of times a day. It needs to make an IMAP connection to Gmail, loop over the emails, save this info to the database and save images locally. Running this task every so often using a cron isn't that big of a deal, but I need to run it every minute and I know eventually the crons will start running on top of each other and cause memory issues. What is the next step up when you need to efficiently run a task multiple times a minute? I've been reading about beanstalk & pheanstalk and I'm not entirely sure if that will do what I need. Thoughts???

  • Generating a error code per property in Hibernate validator

    - by Mike Q
    Hi all, I am looking at using hibernate validator for a requirement of mine. I want to validate a bean where properties may have multiple validation checks. e.g. class MyValidationBean { @NotNull @Length( min = 5, max = 10 ) private String myProperty; } But if this property fails validation I want a specific error code to be associated with the ConstraintViolation, regardless of whether it failed because of @Required or @Length, although I would like to preserve the error message. class MyValidationBean { @NotNull @Length( min = 5, max = 10 ) @ErrorCode( "1234" ) private String myProperty; } Something like the above would be good but it doesn't have to be structured exactly like that. I can't see a way to do this with hibernate validator. Is it possible? Thanks.
