  • Implement a custom editor in Visual Studio 2008 or 2010

    - by David Montgomery
    Hi, I'm trying to find documentation on how one would go about creating a custom editor plug-in for VS2008 or VS2010. The file syntax I want to edit is from a tool called TemplateMaschine by Stefan Sarstedt. An example of the template syntax: <%@ Assembly Name="System.Xml" %> <%@ Import NameSpace="System.Xml" %> <%@ Import NameSpace="System.Collections" %> <%@ Argument Name="className" Type="string" %> <%@ Argument Name="attributes" Type="ArrayList" %> public class <%=className%> { <% foreach(string attr in attributes) { %> public string <%=attr%>; <% } %> } The most important editor features for me would be real-time syntax checking and code completion. If we could get those features, it would save us THOUSANDS of man-hours. Failing to incorporate a custom editor into Studio, maybe there is some open source text editor project out there that might be easy to extend for my purposes? I've looked a little at Eclipse, but I would think code completion won't be an option (also, my Java stinks). Another possibility might be extending the SharpDevelop text editor component. Ideas and suggestions welcome!

  • ASP.Net Gridview paging, pageindex always == 0.

    - by David Archer
    Hi all, Having a slight problem with my ASP.Net 3.5 app. I'm trying to get the program to pick up what page number has been clicked. I'm using ASP.Net's built in AllowPaging="True" function. It's never the same without code, so here it is: ASP.Net: <asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333" GridLines="Vertical" Width="960px" AllowSorting="True" EnableSortingAndPagingCallbacks="True" AllowPaging="True" PageSize="25" > <RowStyle BackColor="#F7F6F3" ForeColor="#333333" /> <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" /> <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" /> <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <EditRowStyle BackColor="#999999" /> <AlternatingRowStyle BackColor="White" ForeColor="#284775" /> </asp:GridView> C#: var fillTable = from ft in db.IncidentDatas where ft.pUserID == Convert.ToInt32(ClientList.SelectedValue.ToString()) select new { Reference = ft.pRef.ToString(), Date = ft.pIncidentDateTime.Value.Date.ToShortDateString(), Time = ft.pIncidentDateTime.Value.TimeOfDay, Premesis = ft.pPremises.ToString(), Latitude = ft.pLat.ToString(), Longitude = ft.pLong.ToString() }; if (fillTable.Count() > 0) { GridView1.DataSource = fillTable; GridView1.DataBind(); var IncidentDetails = fillTable.ToList(); for (int i = 0; i < IncidentDetails.Count(); i++) { int pageno = GridView1.PageIndex; int pagenostart = pageno * 25; if (i >= pagenostart && i < (pagenostart + 25)) { //Processing } } } Any idea why GridView1.PageIndex is always = 0? The thing is, the processing works correctly for the grid view.... it will always go to the correct paging page, but it's always 0 when I try to get the number. Help!

  • Linked XSD files in Visual Studio 2010 - How to work with a file in the Unauthorized Zone

    - by David
    I am trying to view a 3rd Party's XSD file in Visual Studio 2010. The XSD file is stored on my local drive. It includes another XSD file, which is stored in the same folder on my local drive. Visual Studio (or perhaps the underlying .Net framework) will not process the included XSD file, because it is in an "unauthorized zone". This much is explained in the following MSDN blog. Does anybody know how I can authorize this included file, so I can see it in the beautiful new content model view?

  • Unit Testing-- fundamental goal?

    - by David
    Me and my co-workers had a bit of a disagreement last night about unit testing in our PHP/MySQL application. Half of us argued that when unit testing a function within a class, you should mock everything outside of that class and its parents. The other half of us argued that you SHOULDN'T mock anything that is a direct dependancy of the class either. The specific example was our logging mechanism, which happened through a static Logging class, and we had a number of Logging::log() calls in various locations throughout our application. The first half of us said the Logging mechanism should be faked (mocked) because it would be tested in the Logging unit tests. The second half of us argued that we should include the original Logging class in our unit test so that if we make a change to our logging interface, we'll be able to see if it creates problems in other parts of the application due to failing to update the call interface. So I guess the fundamental question is-- do unit tests serve to test the functionality of a single unit in a closed environment, or show the consequences of changes to a single unit in a larger environment? If it's one of these, how do you accomplish the other?

  • Simplest PHP Routing framework .. ?

    - by David
    I'm looking for the simplest implementation of a routing framework in PHP, in a typical PHP environment (Running on Apache, or maybe nginx) .. It's the implementation itself I'm mostly interested in, and how you'd accomplish it. I'm thinking it should handle URL's, with the minimal rewriting possible, (is it really a good idea, to have the same entrypoint for all dynamic requests?!), and it should not mess with the querystring, so I should still be able to fetch GET params with $_GET['var'] as you'd usually do.. So far I have only come across .htaccess solutions that puts everything through an index.php, which is sort of okay. Not sure if there are other ways of doing it. How would you "attach" what URL's fit to what controllers, and the relation between them? I've seen different styles. One huge array, with regular expressions and other stuff to contain the mapping. The one I think I like the best is where each controller declares what map it has, and thereby, you won't have one huge "global" map, but a lot of small ones, each neatly separated. So you'd have something like: class Root { public $map = array( 'startpage' => 'ControllerStartPage' ); } class ControllerStartPage { public $map = array( 'welcome' => 'WelcomeControllerPage' ); } // Etc ... Where: 'http://myapp/' // maps to the Root class 'http://myapp/startpage' // maps to the ControllerStartPage class 'http://myapp/startpage/welcome' // maps to the WelcomeControllerPage class 'http://myapp/startpage/?hello=world' // Should of course have $_GET['hello'] == 'world' What do you think? Do you use anything yourself, or have any ideas? I'm not interested in huge frameworks already solving this problem, but the smallest possible implementation you could think of. I'm having a hard time coming up with a solution satisfying enough, for my own taste. There must be something pleasing out there that handles a sane bootstrapping process of a PHP application without trying to pull a big magic hat over your head, and force you to use "their way", or the highway! ;)

  • Writing a VM - well formed bytecode?

    - by David Titarenco
    Hi, I'm writing a virtual machine in C just for fun. Lame, I know, but luckily I'm on SO so hopefully no one will make fun :) I wrote a really quick'n'dirty VM that reads lines of (my own) ASM and does stuff. Right now, I only have 3 instructions: add, jmp, end. All is well and it's actually pretty cool being able to feed lines (doing it something like write_line(&prog[1], "jmp", regA, regB, 0); and then running the program: while (machine.code_pointer <= BOUNDS && DONE != true) { run_line(&prog[machine.cp]); } I'm using an opcode lookup table (which may not be efficient but it's elegant) in C and everything seems to be working OK. My question is more of a "best practices" question but I do think there's a correct answer to it. I'm making the VM able to read binary files (storing bytes in unsigned char[]) and execute bytecode. My question is: is it the VM's job to make sure the bytecode is well formed or is it just the compiler's job to make sure the binary file it spits out is well formed? I only ask this because what would happen if someone would edit a binary file and screw stuff up (delete arbitrary parts of it, etc). Clearly, the program would be buggy and probably not functional. Is this even the VM's problem? I'm sure that people much smarter than me have figured out solutions to these problems, I'm just curious what they are!

  • log-back and thirdparty writing to stdout. How to stop them getting interleaved.

    - by David Roussel
    First some background. I have a batch-type java process run from a DOS batch script. All the java logging goes to stdout, and the batch script redirects the stdout to a file. (This is good for me because I can ECHO from the script and it gets into the log file, so I can see all the java JVM command line args, which is great for debugging.) I may not I use slf4j API, and for the backend I used to use log4j, but recently switched to logback-classic. Although all my application code uses slf4j, I have a third party library that does it's own logging (not using a standard API) which also gets written to stdout. The problem is that sometimes log lines get mixed up and don't cleanly appear on separate lines. Here is an example of some messed up output: 2010-05-28 18:00:44.783 [thread-1 ] INFO CreditCorrelationElementBuilderImpl - Bump parameters exist for scenario, now attempting bumping. [indexDisplayName=STANDARD_S1_v300] 2010-05-28 18:01:43.517 [thread-1 ] INFO CreditCorrelationElementBuilderImpl - Found adjusted point in data, now applying bump.

So logback must be doing something different. The problem seems to be that although PrintStream.write(byte buf[], int off, int len) is synchronized, however I can see in ch.qos.logback.core.joran.spi.ConsoleTarget that System.out.write(int b) is the only write method called. So inbetween logback outputting each byte, the thirdparty library is managing to write a whole string to the stdout. (Not only is this cause me a problem, but it must also be a little inefficient?) Is there any other fix to this interleaving problem than patching the code to ConsoleTarget so it implments the other write methods? Any nice work arounds. Or should I just file a bug report? Here is my logback.xml: <configuration> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%-16thread] %-5level %-35.35logger{30} - %msg%n</pattern> </encoder> </appender> <root level="DEBUG"> <appender-ref ref="STDOUT" /> </root> </configuration> I'm using logback 0.9.20 with java 1.6.0_07.

  • How to use a proprety/value table in MySQL

    - by David
    I inherited a mysql database that has a table with columns like this: object_id, property, value It holds data like this: 1,first_name,Jane 1,last_name,Doe 1,age,10 1,color,red 2,first_name,Mike 2,last_name,Smith 2,age,20 2,color,blue 3,first_name,John 3,last_name,Doe 3,age,20 3,color,red ... Basically what I want to do is treat this table as a regular table. How would I get the id numbers (or all properties) of a person who is age 20 sorted by last and than first name? So far I have: SELECT object_id FROM table WHERE property = 'age' AND value = '20' union SELECT object_id FROM table WHERE property = 'color' AND value = 'red' But I'm not sure how to go about ordering the data. Thanks

  • How does Rails find models and controllers? How can I get it to load more models?

    - by David
    I'm trying to create a non-ActiveRecord model in app/models/gamestate.rb. Then inside my controller (PlayController) I should be able to do GameState.new, right? No go: NameError (uninitialized constant PlayController::GameState): app/controllers/play_controller.rb:23:in `play' (at least in the development environment) But! If I do have a model called app/models/play.rb, then it's automatically loaded and I can do Play.new. So my question is: how does Rails know which classes to load? What sort of name mangling does it do to get from play#action to PlayController to app/controllers/play_controller.rb to app/models/play.rb? It seems awfully fragile, but maybe a better understanding of how this works would help. And finally, how can I get it to load app/models/gamestate.rb?

  • Downloaded chm is blocked, is there a solution?

    - by David Rutten
    CHM files that are downloaded are often tagged as potentially malicious by Windows, which effectively blocks all the html pages inside of it. There's an easy fix (just unblock the file after you download it), but I was wondering if there's a better way to provide unblocked chm files. What if I were to download the chm file (as a byte stream) from our server inside the application, then write all the data to a file on the disk. Would it still be blocked? Is there another/better way still?

  • Flex NetConnection error: Property onDirtyList not found on flash.net.NetConnection

    - by David Wolever
    I'm having some trouble with NetConnection. The following code makes a connection without issue… var n:NetConnection = new NetConnection(); n.objectEncoding = ObjectEncoding.AMF0; n.addEventListener(NetStatusEvent.NET_STATUS, function(...args):void { trace("HERE"); }); n.connect("rtmp://...host...", ...args); But as soon as the NET_STATUS event handler finishes (ie, hitting "step into" with the debugger), I get this error: ReferenceError: Error #1069: Property onDirtyList not found on flash.net.NetConnection and there is no default value. Error #2044: Unhandled AsyncErrorEvent:. text=Error #2095: flash.net.NetConnection was unable to invoke callback onDirtyList. error=ReferenceError: Error #1069: Property onDirtyList not found on flash.net.NetConnection and there is no default value. at Test/___Test_Application1_creationComplete()[/Users/wolever/Workspace/Test/src/Test.mxml:13] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\core\UIComponent.as:9440] at mx.core::UIComponent/set initialized()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\core\UIComponent.as:1168] at mx.managers::LayoutManager/doPhasedInstantiation()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\managers\LayoutManager.as:718] at Function/http://adobe.com/AS3/2006/builtin::apply() at mx.core::UIComponent/callLaterDispatcher2()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8744] at mx.core::UIComponent/callLaterDispatcher()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8684] Which is kind of scary because onDirtyList only yields two hits on Google. So... Any suggestions?

  • Access Flash Symbol Via Code from an .as Class

    - by David
    Hi, I've got a movie clip symbol in my .fla file that I need to reference in an .as file which is in a subfolder in the project. I select the symbol in the library and edit its properties. Its name is bubble; I Export for ActionScript and Export in frame 1. I give it a class name of Bubble. Now I need to go to my .as class, called SomeClass.as There, I need to reference the symbol, because I want to move it from within related code in that .as file. But if I try bubble.x I get an error. If I try var myBubble:Bubble = new Bubble(); I get 'Access of undefined property myBubble'. I was told that I might try 'importing the document class' but how do you import a class which is in the root directory of your app from within a class that's in a subfolder? (Don't know if this would provide the solution anyway)... Tanks.

  • Aggregate Functions and Group By Problems

    - by David Stein
    If we start with the following simple SQL statement which works. SELECT sor.FPARTNO, sum(sor.FUNETPRICE) FROM sorels sor GROUP BY sor.FPARTNO FPartNo is the part number and the Funetprice is obviously the net price. The user also wants the description and this causes a problem. If I follow up with this: SELECT sor.FPARTNO, sor.fdesc, sum(sor.FUNETPRICE) FROM sorels sor GROUP BY sor.FPARTNO, sor.fdesc If there are multiple variations of the description for that part number, typically very small variations in the text, then I don't actually aggregate on the part number. Make sense? I'm sure this must be simple. How can I return the first fdesc that corresponds to the part number? Any of the description variations would suffice as they are almost entirely identical. Edit: The description is a text field.
