• VIsual Studio : ASP.NET Extra Page Files

  - by Matthew

  Is there any way to write a VS Add-In or something else that would allow me to be able to link files to an ASPX page in ASP.NET. My goal is to be able to have this extra file created with every ASPX page, and then use a custom MS Build Task to analyze those files and do some stuff. So for example, when I created "MyPage.aspx", I'd actually see these files on disk... MyPage.aspx MyPage.aspx.cs MyPage.aspx.designer.cs MyPage.aspx.MyExtension I want to be able to see the file when I expand a page and be able to edit the file. Possible?

• Flagging complex properties as Browsable in the compact framework

  - by Rowland Shaw

  I'm working on a compact framework project and whilst most of the properties are fairly straight forward (I.e. mark them as browsable in the xmta file), I'm struggling to get this to work for more complex types - on the full framework, I'd just implement a custom TypeConverter and go from there, but it seems the CF TypeConverter doesn't have any of the type converting methods to override, which has left me a little stuck? It probably should be blindingly obvious but how would I go about supporting design time property support for more complex types (for the sake of argument, assume I can already convert to and from a string, but I'd prefer to keep this strongly typed, rather than just pretend it was a string and parse it both ways. Where should I be looking to achieve this?

• When should I write my own Look and Feel for Java Swing instead of customizing one?

  - by Jonas

  I have used a few different Look and Feels for Java Swing, but I don't really like anyone to 100% so I often end up with customizing it a lot. Sometimes I am thinking about if it is a better idea to write my own LaF (by extending an existing one), but I don't really know. For the moment, I mostly use Nimbus, but I change all colors (to darker ones) and rewrite the appearance of some components, like sliders and scrollbars. I also mostly customize all tables and I am thinking about to change the look of a few other components. When is it recommended to create a new Look-and-Feel instead of customizing one? What are the pros and cons? I.e. customize Nimbus or create a new one by extending Nimbus? Related article: Creating a Custom Look and Feel (old)

• How do you encrypt data between client and server running in Flash and Java?

  - by ArmlessJohn

  We have a multiclient system where the client is written in Flash and the server is written in Java. Currently, communication is done in Flash by usage of flash.net.Socket and the protocol is written in JSON. The server uses a custom port to receive connections and then proceed to talk with each client. As expected, data is sent and received on both fronts as raw bytes, which are then decoded as needed. We would like to encrypt the communication between clients and server. I have some basic understanding about public/private key encryption, but I do not know what is the best way to exchange keys or what libraries are available (on both languages) to do this. What would be the best strategy to attack this problem and where should I start looking for libraries/methods to implement this encryption?

• PyQt signal between QObjects

  - by geho

  I'm trying to make a view and controller in PyQt where the view is emitting a custom signal when a button is clicked, and the controller has one of its methods connected to the emitted signal. It does not work, however. The respond method is not called when I click the button. Any idea what I did wrong ? import sys from PyQt4.QtCore import * from PyQt4.QtGui import QPushButton, QVBoxLayout, QDialog, QApplication class TestView(QDialog): def __init__(self, parent=None): super(TestView, self).__init__(parent) self.button = QPushButton('Click') layout = QVBoxLayout() layout.addWidget(self.button) self.setLayout(layout) self.connect(self.button, SIGNAL('clicked()'), self.buttonClicked) def buttonClicked(self): self.emit(SIGNAL('request')) class TestController(QObject): def __init__(self, view): self.view = view self.connect(self.view, SIGNAL('request'), self.respond) def respond(self): print 'respond' app = QApplication(sys.argv) dialog = TestView() controller = TestController(dialog) dialog.show() app.exec_()

• Working with EnumSet class in GWT

  - by zenmonkey

  I am having trouble using EnumSet on the client side. I get this runtime error message: java.util.EnumSet.EnumSetImpl is not default instantiable (it must have a zero-argument constructor or no constructors at all) and has no custom serializer. Is this is a known issue? Here is what I am doing (basically a hello world app) Service: String echo (EnumSet<Names> name) throws IllegalArgumentException; Client: echoServ.echo (EnumSet.of(Names.JOHN), new AsyncCallback<String>() { ....... }); Shared enum class enum Names { JOHN, NUMAN, OBAMA }

• Problems with overlapping ChildWindows in Silverlight

  - by Humanier

  Hello, I have a Silverlight application. At some point the app shows a ChildWindow with two datagrids and three buttons on it. One of the buttons is 'Reset To Defaults'. After it's pressed, the app shows another ChildWindow on top of the current one in order to ask confirmation. After the second ChildWindow is closed the first one starts to act funny. It's still changing highlighting of the elements on mouse events (mouseover on a grid element, click on a button). But clicking on the buttons doesn't fire my custom event handlers anymore. The only thing which is working on the ChildWindow is a small cross button created by the framework itself in the upper-right corner of the ChildWindow. I'd be grateful for any ideas on the cause of the problem or how to resolve it. Thanks.

• How to access properties of Access Database Table using C# ADOX?

  - by Sachin G

  I have created MS Access Database using C# ADOX library. I have created one table with several columns. What I want to achieve is when I insert date in one column, the date format should be YYYY-MM-DD and not MM-DD-YYYY. I know its just display format, but I want to access the property which we set when we open access table in design mode, and for column with date data type, set format as Custom (YYYY-MM-DD). I want this to be set at runtime while creating table only. I wanted to know what should be property name that I should use in order to access and set the format property of column?

• Scale div in an upwards direction, instead of down?

  - by Derrick

  I have a custom info window over a google map, sometimes these info windows contain an image. When they do, the info window scales down over the marker it is positioned over as soon as the image has finished loading. So the images take longer to load and the div's position has already been calculated by the time the image is finished loading. I do believe there is a way of checking if an image has finished loaded, but that seems a long route - is there not a simple way with JS or CSS to get the div to scale upwards instead of down. Anyone have any clues?

• Need help with Drupal bulk mail low open rate for legitimate mailing list

  - by Ron Williams

  I've moved from constant contact to Drupal Simplenews/Mimemail/SMTP. Previously the open rate was around 50% for constant contact, but now it's 4-5% for the same list via the mentioned setup. Mail is getting out from the server, but it's having an issue anyway. Here's the setup: -The e-mail list consists of approximately 80,000 addresses which is queued at 10,000 e-mails per cron run (which runs hourly). -The server is a Dual Core2Quad machine with 2GB of RAM. -When mail is being sent, the mail queue will usually go up to ~1000 at the beginning of the hour before reducing to ~250 by the time the next cron occurs. -Newsletter is themed to display custom style for newsletter on send -Newsletter is received by some, but appears to be bounced by many (based on low open rate_ -I've added SPF, domain keys, and a PTR record to the DNS -Server hostname (listed in ptr) is different from hosted domain -Very low spam number via Spamassassin -IP and domain are not blacklisted -Mail goes out via SMTP module on delivery. Any ideas?

• Forcing positive sign on double in .Net String.Format

  - by Max Yaffe

  Context: .Net, C# I want to print a complex number made from two doubles. The sign needs to show on the imaginary part. I'd like to use the default double formatting for each part to minimize the number of characters. I tried using String.Format("{0:+G;-G}{1:+G;-G}j", real, imaginary) but this ended up printing: "+G-Gj". Not quite what I wanted. Is there any way to do this using the G specifier or do I need to do a custom format which would sacrifice auto-switching the exponent, e.g. {1:+#.######e###;-#.######e###}j"

• How can I trigger an image load by clicking other element rather than the image itself (Lazy Load jQuery plugin)?

  - by janoChen

  In the Lazy Load plugin's documentation (A jQuery plugin that loads images only when an event occurs) says: Event can be any jQuery event such as click or mouseover. You can also use your own custom events such as sporty or foobar. Default is to wait until user scrolls down and image appears on the window. To prevent all images to load until their grey placeholder image is clicked you could do: $("img").lazyload({ placeholder : "img/grey.gif", event : "click" }); In this case is clicking the image, but how can I trigger the image load by clicking other element rather than the image itself (say an anchor link/button)?

• User management with aspnet membership provider

  - by 109221793

  Hi guys, Just a general question really. I have taken on the management of an application written in C# MVC that uses the asp.net membership api. With this a user can register, change their password, etc. My application consists of two areas, administrator and user. This adminstrator's area has lots of custom admin functionality relating to the application, however has no functionality utilizing the membership api. I want to be able to use the membership api for user management functions such as resetting a password of a user who has forgotten theirs, lock users out, etc. Are there any resources or articles out there that delve into this aspect of using the membership api? Any help would be appreciated :) thanks

• Combining 2 PHP frameworks that both implement __() internationalization function

  - by mclin

  Never had a question I couldn't google until now, and it may be a doozy: I have a PHP site that combines Wordpress with Kohana - Wordpress for the blog, and Kohana for the custom functionality. This is done using a Wordpress plugin that stitches them together. This works great except they both define a __() internationalization function, with different arguments etc. so once wordpress has overridden kohana's __(), if kohana calls __() it explodes. I'm not that familiar with PHP so this might be naive, but shouldn't this stuff be namespaced? Is there anyway other than changing the source of one or the other framework to allow them to call their own respective __()?

• how to force onLayout

  - by rekisum

  Hi i want to design a custom View where I need to recalculate my layout and redraw when user changes something. To force a onLayout(), the only solution that works for me until now is: onLayout(true, 0, 0, 0, 0); invalidate(); Of course that gives me a lint error and I have to add a @SuppressLint("WrongCall"). So there must be a smarter solution. Calls of forceLayout or requestLayout didn't work. Probably they only put a request on a stack but don't react immediately. As my view has no child elements and I do the drawing inside all by myself, could be I'm bypassing some Android design guides and abusing some principles. Can live with the lint error but maybe someone already found a solution. Thanks!

• Keeping messages in queue in case of receiver crash

  - by John Doe

  Hi, We've a Spring JMS message listener container for receiving messages asynchronously. Using DefaultMessageListenerContainer and in sessionTransacted mode. I understand being in sessionTransacted mode means in case of an exception the message will be put back into the queue. But how can I make sure the message won't be deleted from the queue even if the receiver (which is picked the message) crashes or just the machine running it looses power? At first I thought CLIENT_ACKNOWLEDGE acknowledge mode should save me, but apparently it's not the case, Spring calls .acknowledge() no matter what. So here's my question, how can I guarantee the delivery? Using a custom MessageListenerContainer? Using a transaction manager?

• Why isn't my log4net appender buffering?

  - by Eric

  I've created a custom log4net appender. It descends from log4net.Appender.SmtpAppender which descends from log4net.Appender.BufferingAppenderSkeleton. I programatically setup the following parameters in its constructor: this.Lossy = false; //don't drop any messages this.BufferSize = 3; //buffer up to 3 messages this.Threshold = log4net.Core.Level.Error; //append messages of Error or higher this.Evaluator = new log4net.Core.LevelEvaluator(Level.Off); //don't flush the buffer for any message, regardless of level I expect this would buffer 3 events of level Error or higher and deliver those events when the buffer is filled. However, I'm finding that the events are not buffered at all; instead, SendBuffer() is called immediately every time an error is logged. Is there a mistake in my configuration? Thanks

• Best direction for displaying game graphics in C# App

  - by Mike Webb

  I am making a small game as sort of a test project, nothing major. I just started and am working on the graphics piece, but I'm not sure the best way to draw the graphics to the screen. It is going to be sort of like the old Zelda, so pretty simple using bitmaps and such. I started thinking that I could just paint to a Picture Box control using Drawing.Graphics with the Handle from the control, but this seems cumbersome. I'm also not sure if I can use double buffering with this method either. I looked at XNA, but for now I wanted to use a simple method to display everything. So, my question. Using the current C# windows controls and framework, what is the best approach to displaying game graphics (i.e. Picture Box, build a custom control, etc.)

• Is there a standard format string in ASP.NET to convert 1/2/3/... to 1st/2nd/3rd...?

  - by Dr. Monkey

  I have an integer in an Access database, which is being displayed in ASP.NET. The integer represents the position achieved by a competitor in a sporting event (1st, 2nd, 3rd, etc.), and I'd like to display it with a standard suffix like 'st', 'nd', 'rd' as appropriate, rather than just a naked number. An important limitation is that this is for an assignment which specifies that no VB or C# code be written (in fact it instructs code behind files to be deleted entirely). Ideally I'd like to use a standard format string if available, otherwise perhaps a custom string (I haven't worked with format strings much, and this isn't high enough priority to dedicate significant time to*, but I am very curious about whether there's a standard string for this). (* The assignment is due tonight, and I've learned the hard way that I can't afford to spend time on things that don't get the marks, even if they irk me significantly.)

• How to extend the Turbogears 2.1 login functionality

  - by Marc

  I'm using Turbogears 2.1 and repoze.who/what and am having trouble figuring out how to extend the basic authentication functionality. I am essentially attempting to require users to activate their account via an emailed link before they can login. If they try to login without activating their account, I want to display an appropriate error message. The default Turbogears functionality simply displays one message for all errors. I created my own authentication plugin which works fine. It won't allow users to login if they have not activated their account. However, the problem comes when I try to create the form and display custom error messages. How can I go about doing this? Thanks

• NSColor, 10.6 and Gamma 2.2

  - by Stephen Blinkhorn

  With Snow Leopard the default gamma changed from 1.8 to 2.2. I happen to be working on a few Mac apps that use a very dark custom colour scheme provided by Cocoa. On 10.5 it looks fine but on 10.6 with the new gamma it's much darker and really hard on the eyes. The colour scheme is defined using numerous [NSColor colorWithCalibratedRed:green:blue:alpha:] objects within a theme class. Is there any way to 'convert' an NSColor object so that it displays on 10.6 exactly as it would on 10.5 with the old 1.8 gamma? I know this can be achieved globally from within System Preferences but that's not what I'm after.

• email tracking image duplicate requests

  - by DEH

  I am embedding tracking images within emails that are being sent from a custom-built opt-in CRM system. The image src is an encoded .gif, such as src="12_34_675.gif". The image is served by an ASP.NET httphandler that decodes the src encoding and serves a transparent image. Everything works fine, but some email clients request the image multiple times, creating duplicate entries. Some clients make three calls all within one second, and some seem to make tens of calls over a day or so. Mostly email clients make single calls, but these few duplicates are very perplexing. I know I can code around them, but I'd really like to understand what's going on. I've checked the IIS log files, which show that the duplicate requests are coming from the client machines. I can't think what might be causing these duplicate http requests. Help!

• Kohana v2 - problem with routes

  - by yoda

  Hi, I'm attempting to set some custom routes in Kohana v2. What I'm looking for is some method that allow the system to : follow a pre-defined name to it's related root; redirect the non-matched url's into another controller; To give you a more clear view over the problem, I want the first url parameter to be associated to certain pages (contacts, home, services, about us, etc), and those urls who doesn't match the previous pages would be routed into a controller called products, in order to determine if the first url parameter regards a product name. Here's a sample of what I have : $config['_default'] = 'home'; $config['([a-zA-Z]+)'] = 'products/showcat/$1'; What am I missing here? Thanks in advance!

• Displaying User Relationships Module Blocks

  - by Bob Lerner

  I'm unable to display any of the User Relationships' auto-created blocks in any of my sidebars. I have tried enabling all modules and permissions I can think of, with no success. The block I'm most interested in is the block that would allow users to be invited to an existing relationship (e.g. Friend), but as I say this nor any of the other blocks display. Other Drupal blocks and custom blocks display just fine. The blocks do show up in the blocks listing, and I've tried different ways of configuring them. Any help, or even confirmation that someone has been able to do this with the latest stable versions of Drupal and the User Relationships module, would be appreciated. Thank you.

• Attaching files to WCF REST service responses

  - by David Seiler

  I have a resource that looks something like this: /users/{id}/summary?format={format} When format is "xml" or "json" I respond with a user summary object that gets automagically encoded by WCF - fine so far. But when format equals "pdf", I want my response to consist of a trivial HTTP response body and a PDF file attachment. How is this done? Hacking on WebOperationContext.Current.OutgoingResponse doesn't seem to work, and wouldn't be the right thing even if it did. Including the bits of the file in a CDATA section or something in the response isn't safe. Should I create a subclass of Message, then provide a custom IDispatchMessageFormatter that responds with it? I went a short distance down that path but ultimately found the documentation opaque. What's the right thing?
