  • PHP shorthand syntax

    - by alex
    I've just came across this on GitHub. ($config === NULL) and $config = Kohana::config('email'); Is that the equivalent of if ($config === NULL) { $config = Kohana::config('email'); } Is this commonplace? Would I expect other developers looking at my code if I used that first way to instantly know what it was doing?

  • Catch Multiple Custom Exceptions? - C++

    - by Alex
    Hi all, I'm a student in my first C++ programming class, and I'm working on a project where we have to create multiple custom exception classes, and then in one of our event handlers, use a try/catch block to handle them appropriately. My question is: How do I catch my multiple custom exceptions in my try/catch block? GetMessage() is a custom method in my exception classes that returns the exception explanation as a std::string. Below I've included all the relevant code from my project. Thanks for your help! try/catch block // This is in one of my event handlers, newEnd is a wxTextCtrl try { first.ValidateData(); newEndT = first.ComputeEndTime(); *newEnd << newEndT; } catch (// don't know what do to here) { wxMessageBox(_(e.GetMessage()), _("Something Went Wrong!"), wxOK | wxICON_INFORMATION, this);; } ValidateData() Method void Time::ValidateData() { int startHours, startMins, endHours, endMins; startHours = startTime / MINUTES_TO_HOURS; startMins = startTime % MINUTES_TO_HOURS; endHours = endTime / MINUTES_TO_HOURS; endMins = endTime % MINUTES_TO_HOURS; if (!(startHours <= HOURS_MAX && startHours >= HOURS_MIN)) throw new HourOutOfRangeException("Beginning Time Hour Out of Range!"); if (!(endHours <= HOURS_MAX && endHours >= HOURS_MIN)) throw new HourOutOfRangeException("Ending Time Hour Out of Range!"); if (!(startMins <= MINUTE_MAX && startMins >= MINUTE_MIN)) throw new MinuteOutOfRangeException("Starting Time Minute Out of Range!"); if (!(endMins <= MINUTE_MAX && endMins >= MINUTE_MIN)) throw new MinuteOutOfRangeException("Ending Time Minute Out of Range!"); if(!(timeDifference <= P_MAX && timeDifference >= P_MIN)) throw new PercentageOutOfRangeException("Percentage Change Out of Range!"); if (!(startTime < endTime)) throw new StartEndException("Start Time Cannot Be Less Than End Time!"); } Just one of my custom exception classes, the others have the same structure as this one class HourOutOfRangeException { public: // param constructor // initializes message to passed paramater // preconditions - param will be a string // postconditions - message will be initialized // params a string // no return type HourOutOfRangeException(string pMessage) : message(pMessage) {} // GetMessage is getter for var message // params none // preconditions - none // postconditions - none // returns string string GetMessage() { return message; } // destructor ~HourOutOfRangeException() {} private: string message; };

  • LINQ to SQL: making a "double IN" query crashes

    - by Alex
    I need to do the following thing: var a = from c in DB.Customers where (from t1 in DB.Table1 where t1.Date >= DataTime.Now select t1.ID).Contains(c.ID) && (from t2 in DB.Table2 where t2.Date >= DataTime.Now select t2.ID).Contains(c.ID) select a It doesn't want to run. I get the following error: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. But when I try to run var a = from c in DB.Customers where (from t1 in DB.Table1 where t1.Date >= DataTime.Now select t1.ID).Contains(c.ID) select a OR var a = from c in DB.Customers where (from t2 in DB.Table2 where t2.Date = DataTime.Now select t2.ID).Contains(c.ID) select a It works! I'm sure that there both IN queries contain some customers ids.

  • A regex I have working in Ruby doesn't in PHP; what could the cause be?

    - by Alex R
    I do not know ruby. I am trying to use the following regex that was generated by ruby (namely by http://www.a-k-r.org/abnf/ running on the grammar given rfc1738) in php. It is failing to match in php, but it is successfully matching in ruby. Does anyone see what differences between php's and ruby's handling of regexes that might explain this discrepancy? http:\/\/(?:(?:(?:(?:[0-9a-z]|[0-9a-z](?:[\x2d0-9a-z]?)*[0-9a-z])\x2e)?)*(?:[a-z]|[a-z](?:[\x2d0-9a-z]?)*[0-9a-z])|\d+\x2e\d+\x2e\d+\x2e\d+)(?::\d+)?(?:\/(?:(?:[!\x24'-\x2e0-9_a-z]|%[0-9a-f][0-9a-f]|[&:;=@])?)*(?:(?:\/(?:(?:[!\x24'-\x2e0-9_a-z]|%[0-9a-f][0-9a-f]|[&:;=@])?)*)?)*(?:\x3f(?:(?:[!\x24'-\x2e0-9_a-z]|%[0-9a-f][0-9a-f]|[&:;=@])?)*)?)?/i Since you all love regexes so much, how about an alternate solution. Given the ABNF in an rfc, I want a way (in php) to check if an arbitrary string is in the grammar. APG fails to compile on a 64-bit system, VTC is not Free, and I have not found any other such tools. I would also prefer not to use a regex, but it's the closest I've come to success.

  • Incorporate Wordpress into Kohana 3

    - by alex
    I now need to make a Kohana 3 site have a Wordpress blog. I've seen Kerkness' Kohana For Wordpress, but it seems to be the opposite of what I want. Here are the options I have thought of Style a template to look exactly like the Kohana site (time consuming, non DRY and may not work) Include the blog within an iframe (ugly as all hell) cURL the Wordpress pages in. This of course means I will need to create layers between comment posting, etc, which sounds like too much work. Is there any way I can include a Wordpress blog within an existing Kohana application? Do you have any suggestions? Thanks Update Forgot to mention I have already programmed a model in Kohana to open pages based on their slug. Now I want to put blog content in there, and have the comments and other bits work. I also have installed WP e-Commerce and am wondering if there is any chance I can get that to work.

  • Google Maps custom marker - can the iframe accept one like the static maps?

    - by alex
    I was reading the static maps API, and it says you can include a custom marker in the GET params. You simply link to an image file. I now have a second Google Map within an iframe, and was wondering if you can attach custom markers via the GET params to it? Here is the src attribute of the iframe currently. http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=111+Fake+Street+Noosaville+Queensland+Australia&ie=UTF8&output=embed I can't seem to find the documentation on how to do this, if possible. Is this possible?

  • Limit URL Parameter Length in Web.Config

    - by Alex
    Is it possible to add some kind of restriction to the web.config to limit URL parameter length? I want to prevent people at the earliest possible point from submitting too large URL parameters so the server doesn't get taxed more than necessary in the event that somebody tries to "attack" it with large invalid URL parameters.

  • XNA .FBX Vertex Color Missing

    - by Alex
    When I vertex paint and export my models from Blender (or Maya) for use in my XNA 4.0 project, I somehow lose the vertex color channel for the model. I use no custom model object or content pipelines and my own shader throws me the error: The current vertex declaration does not include all the elements required by the current vertex shader. Color0 is missing. I tryed to reopen the model in other modeling tools and the vertex colors are there. What could cause the vertex color channel to not get loaded in XNA 4.0? Here's a temporary link to the FBX file(server refuses to send a fbx, so rename the .jpg file to .fbx after downloading) http://resources.gamestack.org/BananaBush.jpg

  • Style row banding and selection in tr:table using CSS

    - by Alex Larzelere
    I've got a tr:table that I need to style using CSS. All the normal style functions of a table are working, but row banding and row selection aren't coming up. When I view the rendered source, I'm not seeing a difference in the rows for an id or class to grab on to, and the official documentation doesn't have any attributes for declaring a style class for either. Is this possible and if so what do I need to do to get my CSS to grab onto it? <tr:table id="myTable" value="#{tableValues}" rowBandingInterval="1"> <tr:column> ##Stuff## </tr:column> <tr:column> ##Stuff## </tr:column> <tr:column> ##Stuff## </tr:column> </tr:table> Edit Let me try to clairfy what's happening. First, using the declaration above tells jsf to generate a table, and the attribute rowBandingInterval tells it to give each row alternating colors (If it was set to 2, then it would do 2 rows one color, 2 rows another, 2 rows the original, etc.) Once the page gets rendered into standard html, trinidad (and jsf) apply their own classes and IDs to the html. My normal procedure is to look at the rendered html, find the class that it is appling and add CSS rules for it. However in this case, no additional styles are added (nothing in the rendered html denotes one row to be different from another). So the question is, how do I tell trinidad to either give alternating rows and the user selected row different classes/IDs for me to grab on to with CSS?

  • Stored Procedures In Source Control - Automate Build/Deployment Process

    - by Alex
    My company provides a large .NET service-oriented solution. The services layer interact with a T-SQL back-end consisting of hundreds of tables and stored procedures. Our C# code is in version-control (SVN) but our stored procedures and schema are not. After much lobbying of expedient upper-management, I was allowed to review our (non-existent) build/deployment process to accomplish the following goals: Place schema and stored procedures under source-control. Automate the build/deployment process. I would like to proceed per the accepted answer's strategy in this post but have additional questions: I would like to use Hudson as my build server. Is this a reasonable choice for a C#/SQL solution? What better alternatives should I explore? Assuming I have all triggers, stored-procedures, schema, etc... under source control, and that they are scripted to individual files, how do I generate a build script which will take into account dependencies/references between these items? (SQL Server does this automatically, but it generates one giant script) What does the workflow of performing an update at the client look like? i.e. I have to keep existing table data. How do I roll-back schema changes? I am the only programmer. Several other pseudo-technical staff like to make changes directly inside SQL Management Studio. Is it realistic to expect others to adhere to this solution -- how can I enforce this? Thank you in advance for your help.

  • How do I add a one-to-one relationship in MYSQL?

    +-------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------+-------------+------+-----+---------+-------+ | pid | varchar(99) | YES | | NULL | | +-------+-------------+------+-----+---------+-------+ 1 row in set (0.00 sec) +-------+---------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------+---------------+------+-----+---------+-------+ | pid | varchar(2000) | YES | | NULL | | | recid | varchar(2000) | YES | | NULL | | +-------+---------------+------+-----+---------+-------+ 2 rows in set (0.00 sec) This is my table. pid is just the id of the user. "recid" is a recommended song for that user. I hope to have a list of pid's, and then recommended songs for each person. Of course, in my 2nd table, (pid, recid) would be unique key. How do I do a one-to-one query for this ?

  • Problem with virtual mouse click

    - by Alex
    Hi. I have a program that simulates mouse click. Code is something like this: [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)] public static extern void mouse_event(long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo); private const int MOUSEEVENTF_LEFTDOWN = 0x02; private const int MOUSEEVENTF_LEFTUP = 0x04; public static void DoMouseClick(int x, int y) { Cursor.Position = new Point(x, y); mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, x, y, 0, 0); } This code works perfectly. For example I call this function every 30 minutes. But if I press WINKEY+L (Windows is locked) only cursor is moved but not press occurs. Any ideas?

  • How do I implement "cash out" on my site using PayPal?

    - by Alex
    I have a credit system set up on my site where user A can purchase a document from user B, let's say for 1 credit and user B's account gets credited, let's say for $1. User B can then "cash out" and recieve the money they earned from my (the site's) PayPal account into their PayPal account (let's assume that their email address is valid for now). When user A purchases a credit, they are taken to PayPal where they can login and complete the purchase, for this purpose I have an IPN listener set up on my site that stores credit information to my site's database. However, I can't find a mechanism to send the "cash out" information (i.e. user's email and amount to be paid) to PayPal. To elaborate: I understand that PayPal sends the IPN when someone purchases from me, but how do I post from my site to PayPal when the user clicks the "cash out" button? I have seen mention of Mass Pay, but can't seem to locate any code samples to go from. Am I missing something, or is there perhaps a different (and better) way to do this? Thanks!

  • Setting minOccurs="0" (required) on web service parameters of type int

    - by Alex Angas
    I have an ASP.NET 2.0 web method with the following signature: [WebMethod] public QueryResult[] GetListData( string url, string list, string query, int noOfItems, string titleField) I'm running the disco.exe tool to generate .wsdl and .disco files from this web service for use in SharePoint. The following WSDL for the parameters is being generated: <s:element minOccurs="0" maxOccurs="1" name="url" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="list" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="query" type="s:string" /> <s:element minOccurs="1" maxOccurs="1" name="noOfItems" type="s:int" /> <s:element minOccurs="0" maxOccurs="1" name="titleField" type="s:string" /> Why does the int parameter have minOccurs set to 1 instead of 0 and how do I change it? I've tried using [XmlElementAttribute(IsNullable=false)] in the parameter declaration without success.

  • Alternatives to LINQ To SQL on high loaded pages

    - by Alex
    To begin with, I LOVE LINQ TO SQL. It's so much easier to use than direct querying. But, there's one great problem: it doesn't work well on high loaded requests. I have some actions in my ASP.NET MVC project, that are called hundreds times every minute. I used to have LINQ to SQL there, but since the amount of requests is gigantic, LINQ TO SQL almost always returned "Row not found or changed" or "X of X updates failed". And it's understandable. For instance, I have to increase some value by one with every request. var stat = DB.Stats.First(); stat.Visits++; // .... DB.SubmitChanges(); But while ASP.NET was working on those //... instructions, the stats.Visits value stored in the table got changed. I found a solution, I created a stored procedure UPDATE Stats SET Visits=Visits+1 It works well. Unfortunately now I'm getting more and more moments like that. And it sucks to create stored procedures for all cases. So my question is, how to solve this problem? Are there any alternatives that can work here? I hear that Stackoverflow works with LINQ to SQL. And it's more loaded than my site.

  • VSS keep resetting working folder a the root of the C: drive

    - by Alex
    I have noticed several times (that is it does not happens all the time, but occurs regulary) that VSS has forgoten my working folder settings and re-set it to be a root of the C: drive. It is very annoying to find out that some of the files you have checked out and been working on are not in the same folder where you expect them to be (and it also pollutes the drive with a C:\SubProject1, C:\SubProject2 folders instead of keeping them all inside of C:\Work). Any recomendation to prevent VSS from doing this again and again. And yes, please, don't recomment switching to SVN, CVS, TFS etc - there are the rules I can't change.
