  • ASP.NET / WCF - Execute Server.Execute Asynchronously

    - by user208662
    Hello, I need to run the HttpContext.Current.Server.Execute method in my ASP.NET application. This application has a WCF operation that does some processing. Currently, I am to do my processing correctly from within my WCF operation. However, I would like to do this asynchronously. In an error to attempt this asynchronously, I tried running Server.Execute in the DoWork event handler of a BackgroundWorker. Unfortunately, this throws an error that says "object reference not set to an instance of an object" The HttpContext element is not null. I checked that. It is some property nested in the HttpContext object that appears to be null. However, I have not been able to identify why this won't work. It happens as soon as I move the processing to the BackgroundWorker thread. My question is, how can I asynchronously execute the Server.Execute method? Thank you,

  • T-SQL IsNumeric() and Linq-to-SQL

    - by cdonner
    I need to find the highest value from the database that satisfies a certain formatting convention. Specifically, I would like to fund the highest value that looks like EU999999 ('9' being any digit) select max(col) will return something like 'EUZ...' for instance that I want to exclude. The following query does the trick, but I can't produce this via Linq-to-SQL. There seems to be no translation for the isnumeric() function in SQL Server. select max(col) from table where col like 'EU%' and 1=isnumeric(replace(col, 'EU', '')) Writing a database function, stored procedure, or anything else of that nature is far down the list of my preferred solutions, because this table is central to my app and I cannot easily replace the table object with something else. What's the next-best solution?

  • Add Trace methods to System.Diagnostics.TraceListner

    - by user200295
    I wrote a Log class derived from System.Diagnostics.TraceListener like so public class Log : TraceListener This acts as a wrapper to Log4Net and allows people to use System.Diagnostics Tracing like so Trace.Listeners.Clear(); Trace.Listeners.Add(new Log("MyProgram")); Trace.TraceInformation("Program Starting"); There is a request to add additional tracing levels then the default Trace ones (Error,Warning,Information) I want to have this added to the System.Diagnostics.Trace so it can be used like Trace.TraceVerbose("blah blah"); Trace.TraceAlert("Alert!"); Is there any way I can do this with an extension class? I tried public static class TraceListenerExtensions { public static void TraceVerbose(this Trace trace) {} } but nothing is being exposed on the trace instance being passed in :(

  • Bash alias to open Vim at last cursor position mark

    - by Pierre LaFayette
    The mark " in Vim takes you to your last cursor position. I want to create an alias that will open my Vim instance and jump to that mark; something which is obviously extremely useful. This works from the command line: $ vim -c "'\"" File.cpp Now I want to make an alias for this: $ alias v='vim -c "'\""' Well that's not going to work! You need to escape the first single quote you say... $ alias v='vim -c "\'\""' Hmm. That didn't work either... So I try a whole lot of variations of single quoted and double quoted madness, bang my head against the table and load up stackoverflow in my browser, and here we are. How do I properly escape this alias?

  • Browser Detection Python / mod_python?

    - by cka
    I want to keep some statistics about users and locations in a database. For instance, I would like to store "Mozilla","Firefox","Safari","Chrome","IE", etc... as well as the versions, and possibly the operating system. What I am trying to locate from Python is this string; Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.14) Gecko/2009090216 Ubuntu/9.04 (jaunty) Firefox/3.0.14 Is there an efficient way to use Python or mod_python to detect the http user agent/browser?

  • Why are pieces of my HTML showing up on the page and breaking it? Is it PHP related?

    - by Jason Rhodes
    I've been building a site in PHP, HTML, CSS, and using a healthy dose of jQuery javascript. The site looks absolutely fine on my Mac browsers, but for some reason, when my client uses PC Safari, she's seeing strange bits of my HTML show up on the page. Here are some (small) screenshot examples: Figure 1: This one is just a closing </li> tag that should've been on the Media li element. Not much harm done, but strange. Figure 2: Here this was part of <div class='submenu'> and since the div tag didn't render properly, the entire contents of that div don't get styled correctly by CSS. Figure 3: This last example shows what should have been <a class='top current' href=... but for some reason half of the HTML tag stops being rendered and just gets printed out. So the rest of that list menu is completely broken. Here's the code from the header.php file itself. The main navigation section (seen in the screenshots) is further down, marked by a line of asterisks if you want to skip there. <?php // Setting up location variables if(isset($_GET['page'])) { $page = Page::find_by_slug($_GET['page']); } elseif(isset($_GET['post'])) { $page = Page::find_by_id(4); } else { $page = Page::find_by_id(1); } $post = isset($_GET['post']) ?

  • Localize Currency for iPhone

    - by Meltemi
    I would like my iPhone app to allow the input, display and storage of currency amounts using the appropriate symbol ($, €, £, ¥, etc) for the user. Would NSNumberFormatter do everything I need? What happens when a user switches their locale and these amounts (dollars, yen, etc.) are stored as NSDecimalNumbers. I assume, to be safe, it's necessary to somehow capture the locale at the time of entry and then the currency symbol and store them in my instance along with the NSDecimalNumber ivar so they can be unwrapped and displayed appropriately down the road should the user changed their locale since the time when the item was created? Sorry, I have little localization experience so hoping for a couple quick pointers before diving in. Lastly, any insight on how to you handle this kind of input given the limitations of the iPhone's keyboards?

  • Binding to NSTextField Cell not working, edited value resets to default

    - by cygnus6320
    I'm working on a Core Data document application that dynamically creates NSTableColumns. The data cell type may be a checkbox, slider, etc. Programmatically binding to all cell types works, except for NSTextFieldCell. All NSTextFieldCells fail to bind, and after editing they return to their default value. This happens no matter if they're binding to a string, a number (with an NSNumberFormatter applied), or a date (NSDateFormatter applied). I'm using the following format to do all bindings: NSDictionary *textFieldOpts = [NSDictionary dictionaryWithObjectsAndKeys:@"YES", NSContinuouslyUpdatesValueBindingOption, @"YES", NSValidatesImmediatelyBindingOption, nil]; [aCell bind:@"value" toObject:[[entryAC arrangedObjects] objectAtIndex:0] withKeyPath:@"numberData" options:textFieldOpts]; Again, these statements work if the cell type is anything but an NSTextFieldCell. I threw in an observeValueForKeyPath method to log when the value changes... and for other cell types (NSSliderCell for instance) I can see the value changing, but with the NSTextFieldCell, it never, ever updates. Help!

  • Visual Studio 2008 "Publish" option generates some empty folders

    - by Kevin Pang
    When I right click an ASP.NET MVC solution and select the "Publish" option, the final output it generates contains several empty top-level folders. For instance, the "Service References" folder that gets automatically added when you add a service reference to a web app is generated without any files in it. Why are these folders generated at all if there's no content in them? Is there a way to let Visual Studio know to not bother publishing them? This isn't a big deal since it doesn't really affect the app (and before deploying I can always delete the empty folders), but it's a little annoying.

  • Python equivalent of mysql_real_escape_string, for getting strings safely into MySQL?

    - by AP257
    Hi all Is there a Python equivalent of PHP's mysql_real_escape_string? I'm trying to insert some strings into a MySQL db direct from Python, and keep getting tripped up by quotes in the strings. mysql_string = "INSERT INTO candidate (name, address) VALUES " for k, v in v_dict.iteritems(): mysql_string += " ('" + v_dict['name'] + "', '" + v_dict['address'] + "'), " mysql_string += ";" cursor.execute(mysql_string) I've tried re.escape() but that escapes every non-alphanumeric character in the strings, which isn't what I need - I just need to escape single quotes in this instance (plus more generally anything else that might trip up MySQL). Could do this manually I guess, but is there a smarter way to do it in Python?

  • Are preprocessors obsolete in modern languages?

    - by Earlz
    Hello, I'm making a simple compiler for a simple pet language I'm creating and coming from a C background(though I'm writing it in Ruby) I wondered if a preprocessor is necessary. What do you think? Is a "dumb" preprocessor still necessary in modern languages? Would C#'s conditional compilation capabilities be considered a "preprocessor"? Does every modern language that doesn't include a preprocessor have the utilities necessary to properly replace it? (for instance, the C++ preprocessor is now mostly obsolete(though still depended upon) because of templates.)

  • JBoss Seam - Jetty - Virtualhosting

    - by Walter White
    Hi all, I am trying to cutback on the memory usage of my server and would like to optimize the architecture. I currently deploy 2 separate web applications to Jetty 6.1.22 that correspond to different virtualhosts. They have pretty much the same application stack except one has fewer components and are styled differently (content, images, css, etc.). If I change my design pattern over to EJB / EAR + 2 WARS embedded, will that lower the memory consumption? Will that give me a single instance of JBoss Seam, Quartz, and all of my components? They must use a different datasource. Thanks, Walter

  • Visual Studio 2008 macro only works from the Macro IDE, not the Macro Explorer

    - by Cat
    Edit: Creating a new module in the same VSMacros project fixed the problem. The following macro only works if I open the Macro IDE from Visual Studio and run the macro from there. It'd be much more useful if I could just right click the macro from the Macro Explorer from my Visual Studio instance. I must be doing something obviously wrong, but I've never worked with VS macros before. The MessageBox does not appear in either case. Option Strict Off Option Explicit Off Imports System Imports EnvDTE Imports EnvDTE80 Imports EnvDTE90 Imports System.Diagnostics Imports System.Security.Principal Imports System.Windows.Forms Public Module AttachToSdtProcess Sub AttachToSdtProcess() Try 'If MessageBox.Show("Attach to SDT.exe", "Caption", _ ' MessageBoxButtons.OKCancel) = DialogResult.Cancel Then 'Return 'End If Dim dbg2 As EnvDTE80.Debugger2 = DTE.Debugger Dim trans As EnvDTE80.Transport = dbg2.Transports.Item("Default") Dim compName As String = WindowsIdentity.GetCurrent().Name compName = compName.Substring(0, compName.IndexOf("\")) Dim proc2 As EnvDTE80.Process2 = _ dbg2.GetProcesses(trans, compName).Item("TheExecutable.exe") If proc2 Is Nothing Then MessageBox.Show("Could not find TheExecutable.exe") End If proc2.Attach2(dbgeng) Catch ex As System.Exception MsgBox(ex.Message) End Try End Sub End Module

  • Objective-c string appending causes exception

    - by Dave C
    Hello Everyone, The following code is causing me some problems. The third line causes a program crash... it doesn't happen the first time I step through but somehow later on in the program. If I comment out that third line, the program runs smoothly. NSString *myRequestString = @"text"; int i = 1; myRequestString = [myRequestString stringByAppendingString:[NSString stringWithFormat: @"t=%d", i]]; That code causes this exception: * -[CFString release]: message sent to deallocated instance 0xb4c43fe0 On a side note, can anyone tell me how to concatenate strings in objective-c like any other normal language... I can't believe that there is no concatenation operator. Any and all help is greatly appreciated.

  • Bison: Optional tokens in a single rule.

    - by Simone Margaritelli
    Hi there .. i'm using GNU Bison 2.4.2 to write a grammar for a new language i'm working on and i have a question. When i specify a rule, let's say : statement : T_CLASS T_IDENT '{' T_CLASS_MEMBERS '}' { // create a node for the statement ... } If i have a variation on the rule, for instance statement : T_CLASS T_IDENT T_EXTENDS T_IDENT_LIST '{' T_CLASS_MEMBERS '}' { // create a node for the statement ... } Where (from flex scanner rules) : "class" return T_CLASS; "extends" return T_EXTENDS; [a-zA-Z\_][a-zA-Z0-9\_]* return T_IDENT; (and T_IDENT_LIST is a rule for comma separated identifiers). Is there any way to specify all of this only in one rule, setting somehow the "T_EXTENDS T_IDENT_LIST" as optional? I've already tried with T_CLASS T_IDENT (T_EXTENDS T_IDENT_LIST)? '{' T_CLASS_MEMBERS '}' { // create a node for the statement ... } But Bison gave me an error. Thanks

  • How do I get the member to which my custom attribute was applied?

    - by Sarah Vessels
    I'm creating a custom attribute in C# and I want to do different things based on whether the attribute is applied to a method versus a property. At first I was going to do new StackTrace().GetFrame(1).GetMethod() in my custom attribute constructor to see what method called the attribute constructor, but now I'm unsure what that will give me. What if the attribute was applied to a property? Would GetMethod() return a MethodBase instance for that property? Is there a different way of getting the member to which an attribute was applied in C#? [AttributeUsage(AttributeTargets.Method | AttributeTargets.Property, AllowMultiple = true)] public class MyCustomAttribute : Attribute Update: okay, I might have been asking the wrong question. From within a custom attribute class, how do I get the member (or the class containing the member) to which my custom attribute was applied? Aaronaught suggested against walking up the stack to find the class member to which my attribute was applied, but how else would I get this information from within the constructor of my attribute?

  • Let system time determine animation speed, not program FPS

    - by Anders
    I'm writing a card game in ActionScript 3. Each card is represented by an instance of a class extending movieclip exported from Flash CS4 that contains the card graphics and a flip animation. When I want to flip a card I call gotoAndPlay on this movieclip. When the frame rate slows down all animations take longer to finish. It seems Flash will by default animate movieclips in a way that makes sure all frames in the clip will be drawn. Therefor, when the program frame rate goes below the frame rate of the clip, the animation will be played at a slower pace. I would like to have an animation always play at the same speed and as a consequence always be shown on the screen for the same amount of time. If the frame rate is too slow to show all frames, frames are dropped. Is is possible to tell Flash to animate in this way? If not, what is the easiest way to program this behavior myself?

  • Vim Register Use in Ex Mode

    - by Peck
    Potentially 2 questions in one. I would like to know how to reference a register in Ex mode. For instance, I'm editing a file and I want to save the file with a timestamp (or just datestamp really) appended to it. I know I can set register to the value of a shell commands output using: :let @a = system("date +\"%Y-%m-%d\"") Is there any to dereference this register and insert its value into an Ex command? Something like: :w testfile.<value of "a register> Copying to the system clipboard and pasting would be nice, but doing it in a more generic/programitic way for building on other commands in the future would be nice.

  • What is an "incompletely constructed object"?

    - by Joonas Pulakka
    Goetz's Java Concurrency in Practice, page 41, mentions how this reference can escape during construction. A "don't do this" example: public class ThisEscape { public ThisEscape(EventSource source) { source.registerListener( new EventListener() { public void onEvent(Event e) { doSomething(e); } }); } } Here this is "escaping" via the fact that doSomething(e) refers to the enclosing ThisEscape instance. The book states: Publishing an object from within its constructor can publish an incompletely constructed object. This is true even if the publication is the last statement in the constructor. If the this reference escapes during construction, the object is considered not properly constructed. I don't quite get this. If the publication is the last statement in the constructor, hasn't all the constructing work been done before that? How come is this not valid by then? Apparently there's some voodoo going on after that, but what?

  • Starting to make progress Was [MediaRecorder prepare() causes segfault]

    - by dwilde1
    Folks, I have a situation where my MediaRecorder instance causes a segfault. I'm working with a HTC Hero, Android 1.5+APIs. I've tried all variations, including 3gpp and H.263 and reducing the video resolution to 320x240. What am I missing? The state machine causes 4 MediaPlayer beeps and then turns on the video camera. Here's the pertinent source: UPDATE: ADDING SURFACE CREATE INFO I have rebooted the device based on previous answer to similar question. UPDATE 2: I seem to be following the MediaRecorder state machine perfectly, and if I trap out the MR code, the blank surface displays perfectly and everything else functions perfectly. I can record videos manually and play back via MediaPlayer in my code, so there should be nothing wrong with the underlying code. I've copied sample code on the surface and surfaceHolder code. I've looked at the MR instance in the Debug perspective in Eclipse and see that all (known) variables seem to be instantiated correctly. The setter calls are all now implemented in the exaxct order specced in the state diagram. UPDATE 3: I've tried all permission combinations: CAMERA + RECORD_AUDIO+RECORD_VIDEO, CAMERA only, RECORD_AUDIO+RECORD_VIDEO This is driving me bats! :))) UPDATE 4: starting to work... but with puzzling results. Based on info in bug #5050, I spaced everything out. I have now gotten the recorder to actually save a snippet of video (a whole 2160 bytes!), and I did it by spacing the view visibility, prepare() and start() w.a.a.a.a.a.y out (like several hundred milliseconds for each step). I think what happens is that either bringing the surface VISIBLE has delayed processing or else the start() steps on the prepare() operation before it is complete. What is now happening, however, is that my simple timer tickdown counter is getting clobbered. Is it now that the preview and save operations are causing my main process thread to become unavailable? I'm recording only 10fps at 176x144. Referencing the above code, I've added a timer tickdown after setPreviewDisplay(), prepare() and start(). As I say, it now functions to some degree, but the results still have anomalies. // in activity class definition protected MediaPlayer mPlayer; protected MediaRecorder mRecorder; protected boolean inCapture = false; protected int phaseCapture = 0; protected int durCapturePhase = INF; protected SurfaceView surface; protected SurfaceHolder surfaceHolder; // in onCreate() // panelPreview is an empty LinearLayout surface = new SurfaceView(getApplicationContext()); surfaceHolder = surface.getHolder(); surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); panelPreview.addView(surface); // in timer handler runnable if (mRecorder == null) mRecorder = new MediaRecorder(); mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); mRecorder.setOutputFile(path + "/" + vlip); mRecorder.setVideoSize(320, 240); mRecorder.setVideoFrameRate(15); mRecorder.setPreviewDisplay(surfaceHolder.getSurface()); panelPreview.setVisibility(LinearLayout.VISIBLE); mRecorder.prepare(); mRecorder.start(); Here is a complete log trace for the process run and crash: I/ActivityManager( 80): Start proc com.ejf.convince.jenplus for activity com.ejf.convince.jenplus/.JenPLUS: pid=17738 uid=10075 gids={1006, 3003} I/jdwp (17738): received file descriptor 10 from ADB W/System.err(17738): Can't dispatch DDM chunk 46454154: no handler defined W/System.err(17738): Can't dispatch DDM chunk 4d505251: no handler defined I/WindowManager( 80): Screen status=true, current orientation=-1, SensorEnabled=false I/WindowManager( 80): needSensorRunningLp, mCurrentAppOrientation =-1 I/WindowManager( 80): Enabling listeners W/ActivityThread(17738): Application com.ejf.convince.jenplus is waiting for the debugger on port 8100...

  • Groovy Prototype Object

    - by Holden
    I have a method with an incoming variable, which represents a script. e.g. hello.groovy Foo.init(this) Foo.groovy class Foo { static init(app) { } } What is the best way to add a ton of new functionality to the app variable in the init method? Basically, I would like to add all the functionality of another object to the app object. For instance, if I had another class: class Bar { def a() { } def b() { } } I would like the app object to basically be a new Bar(). In JavaScript, this is easy by using the prototype object, but I cannot seem to get it working in groovy. What is the best way to accomplish this? Or should I be doing something differently?

  • Towards an F# .NET Reflector add-in

    - by CliveT
    When I had the opportunity to spent some time during Red Gate's recent "down tools" week on a project of my choice, the obvious project was an F# add-in for Reflector . To be honest, this was a bit of a misnomer as the amount of time in the designated week for coding was really less than three days, so it was always unlikely that very much progress would be made in such a small amount of time (and that certainly proved to be the case), but I did learn some things from the experiment. Like lots of problems, one useful technique is to take examples, get them to work, and then generalise to get something that works across the board. Unfortunately, I didn't have enough time to do the last stage. The obvious first step is to take a few function definitions, starting with the obvious hello world, moving on to a non-recursive function and finishing with the ubiquitous recursive Fibonacci function. let rec printMessage message  =     printfn  message let foo x  =    (x + 1) let rec fib x  =     if (x >= 2) then (fib (x - 1) + fib (x - 2)) else 1 The major problem in decompiling these simple functions is that Reflector has an in-memory object model that is designed to support object-oriented languages. In particular it has a return statement that allows function bodies to finish early. I used some of the in-built functionality to take the IL and produce an in-memory object model for the language, but then needed to write a transformer to push the return statements to the top of the tree to make it easy to render the code into a functional language. This tree transform works in some scenarios, but not in others where we simply regenerate code that looks more like CPS style. The next thing to get working was library level bindings of values where these values are calculated at runtime. let x = [1 ; 2 ; 3 ; 4] let y = List.map  (fun x -> foo x) x The way that this is translated into a set of classes for the underlying platform means that the code needs to follow references around, from the property exposing the calculated value to the class in which the code for generating the value is embedded. One of the strongest selling points of functional languages is the algebraic datatypes, which allow definitions via standard mathematical-style inductive definitions across the union cases. type Foo =     | Something of int     | Nothing type 'a Foo2 =     | Something2 of 'a     | Nothing2 Such a definition is compiled into a number of classes for the cases of the union, which all inherit from a class representing the type itself. It wasn't too hard to get such a de-compilation happening in the cases I tried. What did I learn from this? Firstly, that there are various bits of functionality inside Reflector that it would be useful for us to allow add-in writers to access. In particular, there are various implementations of the Visitor pattern which implement algorithms such as calculating the number of references for particular variables, and which perform various substitutions which could be more generally useful to add-in writers. I hope to do something about this at some point in the future. Secondly, when you transform a functional language into something that runs on top of an object-based platform, you lose some fidelity in the representation. The F# compiler leaves attributes in place so that tools can tell which classes represent classes from the source program and which are there for purposes of the implementation, allowing the decompiler to regenerate these constructs again. However, decompilation technology is a long way from being able to take unannotated IL and transform it into a program in a different language. For a simple function definition, like Fibonacci, I could write a simple static function and have it come out in F# as the same function, but it would be practically impossible to take a mass of class definitions and have a decompiler translate it automatically into an F# algebraic data type. What have we got out of this? Some data on the feasibility of implementing an F# decompiler inside Reflector, though it's hard at the moment to say how long this would take to do. The work we did is included the 6.5 EAP for Reflector that you can get from the EAP forum. All things considered though, it was a useful way to gain more familiarity with the process of writing an add-in and understand difficulties other add-in authors might experience.
