• WCF, net.tcp, and ASP.NET development server

  - by bryanjonker

  I'm setting up a net.tcp WCF service using instructions here: http://blogs.msdn.com/swiss_dpe_team/archive/2008/02/08/iis-7-support-for-non-http-protocols.aspx One of the steps says to do the following: "If you open the IIS7 management console and you look at the advance setting of our IIS7HostedService Web Application, you will see that in the Enabled Protocols section just http is defined. You now have to add net.tcp (separated by a comma), so that our service will be able to respond also to TCP requests." This is fine, but what if I want to use the Cassini / VS2010 ASP.NET development server to debug (hitting F5 or cntrl-F5)? I don't think there's a way to change the settings in that IIS. Or is there? Are other programmers just so awesome that they don't need to go through the debugger? Or do they use wsHttpBinding?

• Tips on implementing a custom UITextView interface on the iPhone?

  - by Alex

  I am trying to implement a control to edit text that will display the text in multiple colors. None of the solutions I have attempted yet have been good enough. UITextView cannot accomplish this. All of the text must be the same color. Using CoreGraphics to draw the text does not allow the text to be selected. Using a UIWebView, DIV and PRE tags cannot be set to contentEditable on Mobile Safari. Currently playing with using an off-screen TEXTAREA and an on-screen DIV to show the rendered text. This works pretty well, except supporting all of these at the same time seems impossible: click-to-type, click-to-move-cursor, click-and-hold-select/copy/paste. Anyone have any tips on this predicament? I've been trying to find any preexisting library out there that will accomplish this in a good way, to no luck. I'm open to any ideas!

• IM (Instant Messaging) increase or decrease developer's productivity?

  - by GRGodoi

  In my team I have some developers that always have two or three IM windows open. The majority of these windows are not related with the project where they are nor with asking or offering programming help. I also use IM and, off course, some of my "talks" are not related with the job. But I feel that when I am using IM my productivity drops. I mean, there is more "mental" work to change the scope between the task I am doing and the conversation every time a new message arrive. Do you face the same situation? Is there some good practices to avoid this (excluding, off course, stopping using IM)?

• J2ME VS Android VS iPhone VS Symbian VS Windows CE

  - by Sadi

  I have very little idea about mobile platform, though I am interested to program for mobile platform. Would you please compare between J2ME VS Android VS iPhone VS Symbian VS Windows CE. I would like to know which one is better, and if there is any VM technology to test the programs. Which one should I choose and why? Is there any IDE, debugging facilities? Personally I would like to code for open source, but any suggestion are welcome. I have preliminary knowledge on java. I would also like to know, if there is anything else that you can recommended. Thank you

• How do I pass credentials to a machine so I can use Microsoft.Win32.RegistryKey.OpenRemoteBaseKey()

  - by JCCyC

  This .NET API works OK if I'm trying to open the Registry in a machine that's in the same domain as I am (and my logged-on user has admin rights on the target machine). It gets tricky if it's an out-of-domain machine with a different, local administrative user (of whom I do have the password). I tried to use WNetUseConnection() (which has served me well in the past in situations where what I wanted was to read a remote disk file) prior to calling OpenRemoteBaseKey(), but no dice -- I get an access denied exception. Clearly, I must pass credentials some other way, but how?

• How do I determine a best-fit distribution in java?

  - by Eadwacer

  I have a bunch of sets of data (between 50 to 500 points, each of which can take a positive integral value) and need to determine which distribution best describes them. I have done this manually for several of them, but need to automate this going forward. Some of the sets are completely modal (every datum has the value of 15), some are strongly modal or bimodal, some are bell-curves (often skewed and with differing degrees of kertosis/pointiness), some are roughly flat, and there are any number of other possible distributions (possion, power-law, etc.). I need a way to determine which distribution best describes the data and (ideally) also provides me with a fitness metric so that I know how confident I am in the analysis. Existing open-source libraries would be ideal, followed by well documented algorithms that I can implement myself.

• Stack overflow in xp cmd console

  - by Dave

  I am using an older program whose source code I cannot see. I am using the cmd.exe console in windows xp. The program ran with no problems on an xp machine last year, while a stack overflow code 2000 error was observed on a different xp machine (easy fix - use the machine that works). I tried running the program on the previously working machine lately, and now am getting the same error. No changes to the os were made and I did not change the service pack version. Any ideas on how to get around this stack overflow error so I can use the program? Dosbox will at least open the program, however it does not run to completion. Thanks!

• Upload images problem: IO error. (Error #2038)

  - by ile

  I'm using script which is uploading files to server via flash component. Sometimes, very rarely, when trying to upload images via Firefox I get following error: IO error #2038. Searching on the net I could find reason why is it really happening to me. But I found solution for my case: I open IE6, do the same thing there (photos are always uploaded without problem) and the when I try again in Firefox problem disappears. If someone had similar problems maybe this could help or maybe this hint could help to someone discovering cause of the problem :)

• why is this closing the new pop up window

  - by user295189

  I am trying to open a window and then redirecting the original page to a new location. It opens the window, however before redirecting the parent page, it closes the new window too. How can I fix that function orderPrint() { var n = new Object(); n. ID = <?php echo $ID->ID; ?>; n.action = posttothispage.php"; n.target = popWinCenterScreen("/common/html/empty.htm", parseInt(window.screen.height * 0.8), 796, "resize"); myFuction.PostRequest(n); window.location = “someotherpagethanthis.php”; }

• How to get Java Decompiler / JD / JD-Eclipse running in Eclipse Helios

  - by Universalspezialist

  Java Decompiler (JD) is generally recommended as a good, well, Java Decompiler. JD-Eclipse is the Eclipse plugin for JD. I had problems on several different machines to get the plugin running. Whenever I tried to open a .class file, the standard "Source not found" editor would show, displaying lowlevel bytecode disassembly, not the Java source output you'd expect from a decompiler. Installation docs in http://java.decompiler.free.fr/?q=jdeclipse are not bad but quite vague when it comes to troubleshooting. Opening this question to collect additional information: What problems did you encounter before JD was running in Eclipse Helios? What was the solution?

• Could the HTML 5 Video tag pick up an IP Multicast Stream?

  - by DrewBarbs

  I've been researching methods of getting an IP Multicast over UDP to the browser, and have found little that suggests I would be able to do it without using a plug-in like Java, Flash, or Silverlight in order to open a UDP port and (somehow) render the video. Checking out the HTML 5 <video> spec, there is (obviously) little in the way of specific implementation details, so as far as I can tell, there is nothing stopping a browser from parsing a address of the form "udp://224.1.1.1:8000" and joining a multicast group on that IP/port. Is this a correct understanding? Or must the resource pointed to by the <source> be a file?

• RadWindow AlwaysOnTop

  - by klausbyskov

  Does anyone have any experience with the RadWindow wpf control from Telerik? My problem is that when I open a RadWindow and minimize my application then when I maximize the application the RadWindow is not visible. I can use alt+tab to get the RadWindow in front again, but I would really like to avoid having to do this. I'm doing the following to display the RadWindow: this.theWindow.ShowDialog(); Where theWindow is an instance of a class that inherits from RadWindow. Any ideas?

• Oracle analytic functions for "the attribute from the row with the max date"

  - by tpdi

  I'm refactoring a colleague's code, and I have several cases where he's using a cursor to get "the latest row that matches some predicate": His technique is to write the join as a cursor, order it by the date field descending, open the cursor, get the first row, and close the cursor. This requires calling a cursor for each row of the result set that drives this, which is costly for many rows. I'd prefer to be able to join, but what something cheaper than a correlated subquery: select a.id_shared_by_several_rows, a.foo from audit_trail a where a.entry_date = (select max(a.entry_date) from audit_trail b where b.id_shared_by_several_rows = a.id_shared_by_several_rows ); I'm guessing that since this is a common need, there's an Oracle analytic function that does this?

• Editing Data in Child Window with RIA Services and Silverlight 4

  - by Rick Arthur

  Is it possible to edit data in a SilverLight Child window when using RIA Services and Silverlight 4? It sounds like a simple enough question, but I have not been able to get any combination of scenarios to work. Simply put, I am viewing data in a grid that was populated through a DomainDataSource. Instead of editing the data on the same screen (this is the pattern that ALL of the Microsoft samples seem to use), I want to open a child window, edit the data and return. Surely this is a common design pattern. If anyone knows of a sample out there that uses this pattern, a link would be much appreciated. Thanks, Rick Arthur

• How to correctly filter a datatable (datatable.select)

  - by Phil

  Dim dt As New DataTable Dim da As New SqlDataAdapter(s, c) c.Open() If Not IsNothing(da) Then da.Fill(dt) dt.Select("GroupingID = 0") End If GridView1.DataSource = dt GridView1.DataBind() c.Close() When I call da.fill I am inserting all records from my query. I was then hoping to filter them to display only those where the GroupingID is equal to 0. When I run the above code. I am presented with all the data, the filter did not work. Please can you tell me how to get this working correctly. Thanks.

• Port scientific software to GPU and publish it

  - by Werner

  Hi, let's say that I am a physicist and that I am the master of the universe when it comes to port salready existing oftware to GPU's with 100x or more speedups. Let's say that I find that some other scientist, which does not know how to program GPU, publishes the Open Source code in his/her website of a physical simulation program, in the field I am expert on. Let's say that I realize "I can port that code to GPU", and I suggest him, but he shows no interest. My interest here is, 1) to port it to GPU, 2) to publish this result in a scientific journal related with physics and/or computer science My question for you is 1- would you proceed here to port the code to GPU (or other new arch) and publish it? 2- how would you do it and which journal do you suggest? Thanks

• System.Reflection - Global methods aren't available for reflection

  - by mrjoltcola

  I have an issue with a semantic gap between the CLR and System.Reflection. System.Reflection does not (AFAIK) support reflecting on global methods in an assembly. At the assembly level, I must start with the root types. My compiler can produce assemblies with global methods, and my standard bootstrap lib is a dll that includes some global methods. My compiler uses System.Reflection to import assembly metadata at compile time. It seems if I depend on System.Reflection, global methods are not a possibility. The cleanest solution is to convert all of my standard methods to class static methods, but the point is, my language allows global methods, and the CLR supports it, but System.Reflection leaves a gap. ildasm shows the global methods just fine, but I assume it does not use System.Reflection itself and goes right to the metadata and bytecode. Besides System.Reflection, is anyone aware of any other 3rd party reflection or disassembly libs that I could make use of (assuming I will eventually release my compiler as free, BSD licensed open source).

• Switch to tab by typing a substring of its name in Visual Studio 2005

  - by Vineus

  Is there a way to navigate between tabs in VS similar to the emacs iswtichb-mode or Firefox ubiquity switch tab mode (https://wiki.mozilla.org/Labs/Ubiquity/Ubiquity_0.1_Author_Tutorial#Switching_Tabs) ? In these apps, you just type a substring of the title of the tab (or buffer for emacs) to switch to this tab. For instance, to switch to a tab named "App_Code/Data/MyProgram.cs", you just invoke the tab switching command and then type "Progr" for instance to list all the tab whose name matches this string, including "MyProgram.cs". It's much easier to switch between tabs this way when you have a lot of documents open and when you now where to go (which is the case in most situation) Thank you !

• Looking for fully managed WeifenLuo(DockPanel Suite) replacement or hints on implementing one

  - by luiscubal

  I need a WeifenLuo replacement that'll run on both .NET and Mono, on Windows, Linux and Mac, preferrably licensed under the MIT license. I'd appreciate if the API was similar to WeifenLuo's, but I understand that such may not be available. Also, since I couldn't find anything on Google, I believe this might not exist. In this case, I'd like some hints regarding how to implement this. I have some(not much) Windows.Forms experience, and I must not use any P/Invoke. I already know out how to detect window motion and how to create a borderless translucent window on a given position and with a given size. So here are some problems I am facing: WeifenLuo supports multiple left/right/top/bottom panes, allowing them to be resized and contain more than one panel. It also supports splittable tabs. Is there anything else I should be aware of before starting? Are there similar open-source projects available?

  hi, I am in the conversion process of facebook app from fbml to iframe. Now i am testing using few iframe pages. $user = $facebook->require_login(); It gives the current user logged in. Once it get the variable from the facebook.com it saves in cookie by the PHP API provided by facebook). I logged out using another tab of facebook and i tryed using my app without refreshing the whole site (by just using the links inside my app). It still gives the $user variable. It indicates that user has logged in instead of user logged out. Please help me out. I want my app secured. It looks my iframe app accessible when we select "open this frame in new window". I need a solution for this too. Thanks in advance.
