  • XHTML 1.0 DocType ignored in all browsers?

    - by John
    I was testing this, since I understood using XHTML let me use any valid XML for empty <div> elements: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"> <title>Test</title> </head> <body> <div style="border:solid 10px black; width:100px; height:100px"></div> <div style="border:solid 10px red; width:100px; height:100px"></div> <div style="border:solid 10px blue; width:100px; height:100px"></div> <div style="border:solid 10px black; width:100px; height:100px" /> <div style="border:solid 10px red; width:100px; height:100px" /> <div style="border:solid 10px blue; width:100px; height:100px" /> </body> </html> It doesn't work in any browser I try... this is how FireBug tells me it understands the document: <html> <head> <meta content="text/html;charset=utf-8" http-equiv="Content-Type"/> <title>Test</title> </head> <body> <div style="border: 10px solid black; width: 100px; height: 100px;"/> <div style="border: 10px solid red; width: 100px; height: 100px;"/> <div style="border: 10px solid blue; width: 100px; height: 100px;"/> <div style="border: 10px solid black; width: 100px; height: 100px;"> <div style="border: 10px solid red; width: 100px; height: 100px;"> <div style="border: 10px solid blue; width: 100px; height: 100px;"/> </div> </div> </body> </html> I'm a bit confused what the point is of using XHTML if I have to do this, I might as well just use HTML? Note, that setting the content type to content="application/xhtml+xml" makes no difference in FF3 at least.

  • c++: truth assignment warning with arguments?

    - by John
    I use the following to work with arguments in my programs, but it seems to just hand me a warning (just a warning): "warning: suggest parentheses around assignment used as truth value" The beginning of the code is as follows: enum{OPT_DISP_H = 0x2, OPT_DISP_W = 0x1}; int main(int argc, char *argv[]) { int opt = 0x00; char c; while((++argv)[0] && argv[0][0]=='-'){ while(c =* ++argv[0]) switch(c){ case 'h': opt |= OPT_DISP_H; break; //etc.. The while(c =* ++argv[0]) part being where the warning persists. The code works fine, but what does this warning mean opposed to what is used? I think the code is c = *++argv[0], using the pointer. So why does the single = work and what is really recommended to be used?

  • Sequential searching with sorted linked lists

    - by John Graveston
    struct Record_node* Sequential_search(struct Record_node *List, int target) { struct Record_node *cur; cur = List->head ; if(cur == NULL || cur->key >= target) { return NULL; } while(cur->next != NULL) { if(cur->next->key >= target) { return cur; } cur = cur->next; } return cur; } I cannot interpret this pseudocode. Can anybody explain to me how this program works and flows? Given this pseudocode that searches for a value in a linked list and a list that is in an ascending order, what would this program return? a. The largest value in the list that is smaller than target b. The largest value in the list that is smaller than or same as target c. The smallest value in the list that is larger than or same as target d. Target e. The smallest value in the list that is larger than target And say that List is [1, 2, 4, 5, 9, 20, 20, 24, 44, 69, 70, 71, 74, 77, 92] and target 15, how many comparisons are occurred? (here, comparison means comparing the value of target)

  • Which PHP calendar will suit my needs? Or build my own?

    - by John
    There are so many web based calendars out there that I'm not sure which will best suit my purposes. I want to create an events calendar, which I suppose looks and functions in much the same way as google calendar. But users shouldn't need to sign up for a gmail account or a google account. Users of my social network website should be able to create events in the calendar and share it with other friends in their "friend network". In month, year or day views, you can mouse hover events to see a bubble dialog that lists events in detail. People need to pay a monthly fee to use my website (not sure if this prevents me from using google apps). So is something like Google Calendar the way to go? Or are there other php/javascript calendars out there that already meet my needs? Or will it just save me more time to build my own?

  • Method-Object pairs in Java

    - by John Manak
    I'd like to create a list of method-object pairs. Each method is a function returning a boolean. Then: foreach(pair) { if method evaluates to true { do something with the object } } One way of modelling this that I can think of is to have a class Constraint with a method isValid() and for each constraint produce an anonymous class (overriding the isValid() method). I feel like there could be a nicer way. Can you think of any?

  • Subsonic : Same column name different tables

    - by John Transformer
    Hi, I have a query where I need to do a "Where" clause for two different columns in two different tables but subsonic creates the same parametrized parameter name for both which is causing an issue. How can I fix this? string _RawSql = new Select() .From(Tables.Table1) .InnerJoin(Tables.Table2) .InnerJoin(Table3.SidColumn, Table2.Table3SidColumn) .Where(Table1.SidColumn).IsEqualTo(2) .And(Table3.SidColumn).IsEqualTo(1) .BuildSqlStatement(); The query this is creating is SELECT .... FROM [dbo].[Table1] INNER JOIN [dbo].[Table2] ON [dbo].[Table1].[Table2Sid] = [dbo].[Table2].[Sid] INNER JOIN [dbo].[Table3] ON [dbo].[Table2].[Table3Sid] = [dbo].[Table3].[Sid] WHERE [dbo].[Table1].[Sid] = @Sid AND [dbo].[Table3].[Sid] = @Sid Note that in the last two lines its using @Sid for both Table1 and Table3. How go I do it so it uses @Sid0 and @Sid1? Any help would be appreciated. Thanks

  • Firing PropertyChanged event in a complex, nested type in WPF

    - by John
    Hey I have a question about the PropertyChanged vent firing in WPF whne it is used in a complex type. I have a class called DataStore and a list of Departments (an ObservableCollection), and each department again has a list of Products. Properties in the Product class that are changed also affect properties in the Department and DataStore class. How does each Product notify the Department it belongs to, and the DataStore (which is the mother class of all) that one or more of its properties have changed their values? Example: a product has a property NumberSoldToday and is bound. The Department has a property called TotalNumberOfProductsSold: public int TotalNumberOfProductsSold { get { int result = 0; foreach(Product p in this.products) result += p.NumberSoldToday; return result; } } And the data store has a property TotalProductsSold (for all departments): public int TotalProductsSold { get { int result = 0; foreach(Product p in this.deparments) result += p.TotalNumberOfProductsSold; return result; } } If all these properties are bound, and the innermost property changes, it must somehow notify that the value of the other 2 changed as well. How? The only way I can see this happening is to hook up the PropertyChanged event in each class. Th event must also fire when deleting, adding to the collection of products and deparments, respectively. Is there a better, more clever way to do this?

  • Templating Word Documents in C#

    - by NullGeo
    I was wondering if there is a library out there such that it could give me the ability to fill in word templates with custom values. For example: Following could be the content of the Word Document {Address} {PhoneNumber} Hello {Name}, How are you doing? In C# I would like to do something like this to replace all the placeholders in the Word document: using(WordDocument doc = WordDocument.Load("Mail.docx")){ var person = new {Name = "John Smith", Address="42 Wallaby Way, Sydney", PhoneNumber="555-555-5555"}; doc.Template(person); doc.Print(); } The resulting document would look like this: 42 Wallaby Way, Sydney 555-555-5555 Hello John Smith, How are you doing? Any libraries out there (preferably free) that let's me do this? Edit: I am not asking you to find anything that let's me do this. If that was the case, I would do a Google search by myself. Honestly, all I am asking is "has anybody used a library in the past to do this exact thing."

  • Have an external java application by notified of changes to Entity EJBs in JBoss AS

    - by John
    I'm trying to connect an external application to a JBoss AS container. The external application is a Java application that is currently being notified of changes to database entities through a JMS topic. I've added an EntityLifecycleListener class to all my entities that publishes a serialized (and unwrapped) copy of the entity to the JMS topic. The problem is that this implementation ignores the transaction boundaries of the JBoss container. For example, the @PostUpdate event can be fire, generating the JMS message for that entity, but the transaction could be rolled back causing the external application to be notified of an invalid change and become unsync'd. I need my external application to only be notified of successful commits to the database, but I need to be able to publish the entire java POJO to the external application. Is there an official way of doing this?

  • Correct term for PSD to HTML to CMS

    - by John Magnolia
    Hi, I have heard a lot of different terms to describe the process of turning a website design into a editable CMS. Currently I take the design and "slice" this up into HTML and CSS then I "plug" this into a CMS. I would class this as frontend development depending on the level of customisation required for the CMS. The reason I ask is I am currently writing up my CV and have become stuck on the correct term for this. Kind Regards

  • Released object crashes app

    - by John Smith
    I am using objective-C++ (+Boost) for iPhone development. I am in a rather tight loop and need to allocate and release a certain object. The code is something like this. for (int i=0;i<100;i++) { opt = [[FObj alloc] init]; //do stuff with opt [opt release]; } The FObj object is something like @interface FObj MyCPPObj * cppobj; @end In the implementation of FObj there is a dealloc method: -(void) dealloc { delete cppobj; //previously allocated with 'new' [super dealloc]; } I am afraid that if i don't release then the 'MyCPPObj's will just pile up. But releasing makes the app crash after the first loop. What am I doing wrong? Or perhaps should I make cppobj and boost::shared_ptr? (do boost shared pointers automatically release their objects when an objective-C++ object is deleted?)

  • Magento - determine which xml layout file a page is using?

    - by John
    I tried reading the documentation but I still don’t really understand how magento's xml layout files work. In the directory app/design/frontend/default/modern/layout, i see a lot of xml files. How do I determine which xml file any given page on the website is using? For example, if I were on the home page at http://mysite.com, which layout xml file am I using? What if I’m on http://mysite.com/hello-world, which xml file then?

  • Lua-Objective-C bridge on the iphone

    - by John Smith
    I have partially ported the LuaObjCBridge to the iPhone. Most things work but there are still some issues I have to deal with. There are sections where #defines are defined with-respect-to intel or ppc. Is the ARM chip closer to intel or ppc? Here is the most relevant section where most of the defines are: #if defined(__ppc__)||defined(__PPC__)||defined(__powerpc__) #define LUA_OBJC_METHODCALL_INT_IS_SHORTEST_INTEGRAL_TYPE #define LUA_OBJC_METHODCALL_PASS_FLOATS_IN_MARG_HEADER #define LUA_OBJC_POWER_ALIGNMENT #elif defined(__i386__)||defined(__arm__) #warning LuaObjCBridge is not fully tested for use on Intel chips. #define LUA_OBJC_METHODCALL_RETURN_STRUCTS_DIRECTLY // Use this or the code was crashing for me for structs LUA_OBJC_METHODCALL_RETURN_STRUCTS_DIRECTLY_LIMIT #define LUA_OBJC_METHODCALL_USE_OBJC_MSGSENDV_FPRET #define LUA_OBJC_METHODCALL_RETURN_STRUCTS_DIRECTLY_LIMIT 8 #define LUA_OBJC_INTEL_ALIGNMENT #endif For now I added arm with i386, but I could be wrong

  • How to test if an array contains a pair of numbers whose product is odd?

    - by John
    How can I write a function that takes an array of integers and returns true if their exists a pair of numbers whose product is odd? What are the properties of odd integers? And of course, how do you write this function in Java? Also, maybe a short explanation of how you went about formulating an algorithm for the actual implementation. Yes, this is a function out of a textbook. No, this is not homework—I'm just trying to learn, so please no "do your own homework comments."

  • doxygen with IDL/ODL

    - by John
    If you have a C++ project that has a bunch of .ODL files and the generated .h files from the ODL compiler, should doxygen be told to parse both .odl and .h, or only one or the other? In general I don't like documenting generated code but IDL is sort of a special case. In any case, it seems like the member listing of ODL files is not quite working properly in my tests, are ODL files properly parsed?

  • Javascript split with RegEx

    - by Rohan
    Hey again, I just asked a question about Regex, and received a great answer: http://stackoverflow.com/questions/3047201/javascript-split-without-losing-character Now, I have another question. My current Regex looks like this: var split = text.split(/(?=\w*\d*\d:\d\d)/); Basically, I'm trying to split using the timestamps (eg - 9:30 or 10:30, the difference between them is the extra digit in the latter). How do I go about this? Currently, if I have these two: 9:30 pm The user did action A. 10:30 pm Welcome, user John Doe. The splits are : 9:30 pm The user did action A. ---- 1 ---- 0:30 pm Welcome, user John Doe. How do I add an optional check for the first character in the timestamp? Thanks!

  • R: How to write out a data.frame so that I can paste it into SO for others to read?

    - by John
    I have a large data.frame displaying some weird properties when plotted. I'd like to ask a question about it on Stackoverflow, to do that I'd like to write the data.frame out in a form that I can paste it into SO and somebody else can easily run it and have it back into a data.frame object again. Is there an easy way to accomplish this? Also, if it is really long, should I use paste bin instead of directly paste it here?

  • How and/or Why is Merging in GIT Better than in SVN?

    - by John
    I've heard a few places that one of the main ways distributed version control systems shine, is much better merging than traditional tools like SVN. Is this actually due to inherent differences in how the two systems work, or do specific DVCS implementations like GIT/Mercurial just have cleverer merging algorithms than SVN?

  • C# - Erase all property values from a class?

    - by John M
    In a C# Winforms (3.5) application I have added a class that contains many properties (get/set) used to stored values from a 12 form long process. After form 12 I would like wipe out all the property values in the storing class so that the next user won't accidentally record values when starting the process at form 1. Is it possible to erase/destroy/dispose of all property values in a class? My class looks like this: private static int battery; public int Battery { get { return storeInspectionValues.battery; } set { storeInspectionValues.battery = value; } }
