• RST packet sent by the server

  - by intoTHEwild

  I am developing a client in Flash and using http req/resp to communicate with the server. For a while the session works fine and then the connection is terminated by the server. I did a wireshark sniff at the server and the last message which it sends is a RST packet. Also it happens only when I'm using IE and the server and client are in different domains. This does not happen in FireFox. I have been struggling to find a sol, till I found this thread. It's a bit old but I hope I could get some help. I am not sure if this bit of info is important but I am connecting to the server via a gateway. Any clue or suggestions for where should I look into to locate the problem ?

• PHP: Facebook stream.publish and outdated template bundles?

  - by AFK

  Ok So I haven't tried messing with the facebook PHP API for months.. it's gross. Since template bundles are apparently now defunct, how can I publish a story into my users news feed for their friends? I've also already requested permissions. Edit: The issue seems to arise from requested permissions not being set for the user when They are granted. So far I have this $appapikey = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'; $appsecret = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'; $facebook = new Facebook($appapikey, $appsecret); $fb_user = $facebook->require_login(); try { $facebook->api_client->feed_publishUserAction(); } catch(Exception $e) { } edit: I've looked through the facebook "api documentation" multiple times it's just not clear to me. I can't tell what's actually deprecated or not. They link to tutorials 2-3 years old! if you have a problem with your iframe application reloading over and over and over try using $facebook-require_frame()

• Socket server stops accepting connections after a period of time

  - by Rob

  We have an async socket server written in C#. (running on Windows Web Server 2008) It works flawlessly up until it stop accepting new connections for an unknown reason. We have about 200 concurrent connections on average, however we keep a count of both connections created and connections dropped. These figures can reach as high as 10,000 or as low as only 1000 before it just stops! It can run for up to around 8 hours sometimes before it stops or it can run for about half hour, at the moment it's running for about an hour before we have another application bring it back up automatically when that can't connect (not exactly ideal). It doesn't appear like we're running out of sockets as we're closing them properly, we're also logging all errors and nothing is happening immediately before it stops. We can figure this out. Does anyone have any ideas what might be going on? I can paste code, but it generally just the same old async beginaccept/send code you see everywhere.

• How does struts 1.X ActionForm handle pure html checkbox list?

  - by BlueDolphin

  I am dealing with an old application which uses struts 1.2. And for some reason, we are using pure html form to submit to struts action. For example: for the content output of testAction.do, I try to submit to itself. item 1 item 2 Then I associate an form bean TestForm with testAction. I am not sure how to specify the properties in the form so that it take the value from myitem1 after user click "submit" I tried to add getMyitem1(), setMyitem1(String[] items), getSelectedMyitem1(), setSelectedMyitem1(String[] items) Those set methods are only called when page are loaded. I guess my understanding of ActionForm in struts 1.x must be wrong. Please advise, thanks.

• update columns when value is numeric in tsql

  - by knittl

  i want to normalize date fields from an old badly designed db dump. i now need to update every row, where the datefield only contains the year. update table set date = '01.01.' + date where date like '____' and isnumeric(date) = 1 and date >= 1950 but this will not work, because sql does not do short circuit evaluation of boolean expressions. thus i get an error "error converting nvarchar '01.07.1989' to int" is there a way to work around this? the column also contains strings with a length of 4, which are not numbers (????, 5/96, 70/8, etc.) the table only has 60000 rows

• Changing <img src="XXX" />, js event when new image has finished loading?

  - by carillonator

  I have a photo gallery web page where a single <img src="XXX" /> element's src is changed (on a click) with javascript to show the next image—a poor man's ajax I guess. Works great on faster connections when the new image appears almost immediately. Even if it takes a few seconds to load, every browser I've tested it on keeps the old image in place until the new one is completely loaded. It's a little confusing waiting those few seconds on a slow connection, though, and I'm wondering if there's some javascript event that fires when the new image is done loading, allowing me to put a little working... animated gif or something up in the meantime. I know I could use AJAX for real (I'm using jQuery already), but this is such a nice and simple solution. Besides this lag, is there any other reason I should stay away from this approach to changing images? thanks.

• Unable to add Solution to TFS 2010 due to existing (invisible)binding

  - by Refracted Paladin

  I have a smallish utility library I made that I had created in TFS Beta 2 to test out TFS. I now have TFS rc1 installed(and Beta 2 uninstalled) and am trying to add my Solution to TFS. I get an error saying that it is already bound to my old TFS, which was on a different system then this one. Strangely, when I go into Source Control and look at the bindings it says there aren't any. Also, I manually deleted the .vss and .vsc files and it still does it. Ideas? I looked through the numerous other SO topics related to this but unless I missed one none of them are dealing with my issue. Ideas?

• C/C++ enum and char * array

  - by Eric M

  Ran accross the following code in an article and didn't think it was standard C/C++ syntax for the char* array. As a test, both Visual C++ (visual studio 2005) and C++ Builder Rad XE both reject the 2nd line. Without using #defines, anyone have any tricks/tips for keeping enums and a string array sort of in sync without resorting to STL ? More of a curiosity question. enum TCOLOR { RED, GREEN, BLUE }; char *TNCOLOR[] = { [RED]="Red", [GREEN]="Green", [BLUE]="Blue" }; as an aside, the article this came from is quite old and I believe this might work under GCC but have not tested.

• Clear Input onFocus with Google Custom Search

  - by Wes

  I'm moving a sites search over to google custom search. The old input for text looks like this: <input type="text" value="Search this website..." name="s" id="searchbox" onfocus="if (this.value == 'Search this website...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search this website...';}" /> Now I need to Have the attr 'name' as 'q', like so: <input type="text" value="Search this website..." name="q" id="searchbox" onfocus="if (this.value == 'Search this website...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search this website...';}" /> The odd thing is that when I swap the name over to q, I'm unable to clear the search box on focus. Am I missing something super easy?

• Apache, and logrotate instances

  - by OlivierDofus

  Hi! If I have one website and I want to rotate its logs, there's one instance of logrotate that is launched. There are as many logrotate instances launched as they are virtual websites. Here you can find mod_log_rotate, with a 1.3 version and (only) 2.0 version: http://www.hexten.net/wiki/index.php/Mod-log-rotate It's 6 years old. Is there something new, or maybe is there something like that in recent Apache versions? I didn't find anything like that, and I don't know if this code is still "usable" for recent Apache versions (2.2.x) Don't hesitate to edit my post to make it proper English, thanks a lot!

• Check whether Excel file is Password protected

  - by Torben Klein

  I am trying to open an Excel (xlsm) file via VBA. It may or may not be protected with a (known) password. I am using this code: On Error Resume Next Workbooks.Open filename, Password:=user_entered_pw opened = (Err.Number=0) On Error Goto 0 Now, this works fine if the workbook has a password. But if it is unprotected, it can NOT be opened. Apparently this is a bug in XL2007 if there is also workbook structure protection active. (http://vbaadventures.blogspot.com/2009/01/possible-error-in-excel-2007.html). On old XL2003, supplying a password would open both unprotected and password protected file. I tried: Workbooks.Open filename, Password:=user_entered_pw If (Err.Number <> 0) Then workbooks.open filename This works for unprotected and protected file. However if the user enters a wrong password it runs into the second line and pops up the "enter password" prompt, which I do not want. How to get around this?

• Error including image in Latex

  - by euphoria83

  I am getting the following error while compiling my Latex File : ! LaTeX Error: Cannot determine size of graphic in tree.jpg (no BoundingBox). Why do I get this error ? What has this to do with an .eps file ? Infact, I could compile it fine with MacTex on my machine. But when I submit it online to a scientific journal for publication, it compiles it on the server and sends me the resultant PDF which as all these error that prevent it from compiling. I am using the following syntax for including the images : \begin{figure}[!h] \begin{center} \scalebox{0.45}{ \includegraphics{tree.jpg}} \end{center} \caption{\small A sample} \label{tree} \end{figure} What should I do ? Could it be that their server is using an old compiler ? UPDATE : It finally worked. I converted the first image to PDF and the compilation happened perfectly. I guess it used the bounding box value from that PDF and applied it to all images.

• Should one use PHP to print all of a page's HTML?

  - by Mala

  Hi So I've always developed PHP pages like this: <?php goes at the top, ?> goes at the bottom, and all the HTML gets either print()ed or echo()ed out. Is that slower than having non-dynamic html outputted outside of <?php ?> tags? I can't seem to find any info about this. Thanks! --Mala UPDATE: the consesus seems to be on doing it my old way being hard to read. This is not the case if you break your strings up line by line as in: print("\n". "first line goes here\n". "second line goes here\n". "third line"); etc. It actually makes it a lot easier to read than having html outside of php structures, as this way everything is properly indented. That being said, it involves a lot of string concatenation.

• How to clear cache for previously installed InfoPath forms on a client computer?

  - by user313067

  Hi folks, We recently had a strange issue with an InfoPath 2007 form being opened from SharePoint 2007 and receiving the error message "the system cannot find the file specified". To be clear, this was not a form services enabled form. Anyway, after spending way too much time trying to figure out what was going on (nothing in the MOSS 2007 server log files), we determined that the user had previously installed an older version of the form (but with the same name) on their workstation using a no longer available msi file (meaning we could not uninstall it from the workstation). So I wanted to pass on a very simple solution for anyone who is unfortunate to run into this problem in the future (since I lost a great deal of hair over it): Fire up regedit, go to HKEY_LOCALMACHINE-Software-Microsoft-Office-InfoPath-SolutionsCatalog. Locate the key that has the previously installed form name, and delete it. This will cause InfoPath to stop trying to open the form locally (which is either old or doesn't exist) and force it to open your form from SharePoint. Hope this helps someone!

• creating a wordpress dev enviornment and uploading to production

  - by Jeff

  I am an old school java developer who is considering a using wordpress. I'm used to developing locally on my PC (yeah yeah not even a mac) and then ftping my files up to a production environment on a remote server. My high level review of wordpress gives me the impression that typically there is no concept of lower environments and that all updates occur directly in production. Is this the case? If not, can someone explain how one goes about uploading the files to a web site? Thanks, Jeff

• What are the reasons to use SQL Server instead of MySQL with a complex .Net project?

  - by cdeszaq

  We currently have a 10 year old nasty, spaghetti-code-style SQL Server database that we are soon looking to pretty much re-write from scratch as part of a re-write to a large web application. (The existing application will serve as the functional requirements for the next incarnation of the app) The new version will be developed in .Net, so a large portion of the application stack will be based on Microsoft technologies (Visual Studio will be used IIS will be the application server). One of the developers on the project has raised the possibility of switching to MySQL instead of SQL Server in order to save on cost for both the licence of the DB server, as well as the tools to design and manipulate the DB (such as the wonderfully free MySQL Workbench). What are the various pros and cons of using SQL Server vs. MySQL as the database for a complex .Net project? Price is one factor we have identified, both in terms of the DB server licence as well as tools to manipulate the DB, but what other factors come into play?

• Is it better to comment out unneeded code or delete it?

  - by Matt Connolly

  For web applications under maintenance, assuming you have source control, when you need to remove part of the UI and the associated code, do you delete the code and check in, or do you comment out the old code? Arguments in favor of deleting: cleaner code, can still see deleted code in source control history, no worrying about refactoring code that might be uncommented some day. Arguments in favor of commenting: sometimes you need to add the feature back in and the developer adding it back in may not know to check source control history, sometimes the code represents unique functionality that can be a handy reference, seeing it all in one place can help provide clues to deciphering the active code.

• How to break a series of git commits into patches for submission to another project

  - by krosenvold

  So I've been bashing away at my favorite open source project for quite some time, and It's time for submitting issues with patches back. I have to regroup my commits more or less fully, and hopefully extract some pieces of code that can function as distinct patches to avoid code bombing. Currently I usually do something like this: rebase/squash everything to one commit since the old ones often don't make sense as patches undo that commit start adding stuff that I think fits to one commit, using add/add -i commit stash the rest test that commit re-apply the stash and start from 3 until all is accounted for It works, but is there a better way ?

• Reference non-GAC version of DLL in Visual Studio 2010

  - by Eric J.

  This is similar to Add Non-GAC reference to project but the solutions presented there don't seem to help. I have a WinForms UI Library (Krypton from ComponentFactory) installed in the GAC. There's a bug I want to track down in that library, so I added the source code to my solution, removed the old references from my WinForms project to Krypton DLLs, added them back as a project references, ensured Copy Local is set to true, double-checked that the path (on reference properties tab) points to my local project, and... ...the GAC version is still being used while debugging. I cannot set a breakpoint in the Krypton source, Debugger.Break() or other code changes to not execute, and when I start the Visual Studio 2010 debugger, I see a Loading from ... GAC_MISL message relating to the Krypton DLLs flash by in the VS 2010 status bar. The DLLs are not copied to the WinForm's Debug folder. How can I reference the "project" version of the files while debugging while leaving them registered in the GAC?

• Unable to remove package from Delphi 2005

  - by Robo

  I needed to reinstall a package, DrRX.bpl. I removed it from the package list, and trying to install a newer version of the same package. I've replaced the old component's dir with the new one. When I open the new DrRX.bpl and click install, I get the error "Package C:\Program Files\Borland\BDS\3.0\components\rx work\output\DrRx.bpl cannot be installed because another package with the same basename is already loaded (DrRx.bpl)" I cannot find any reference to DrRX in my package list, DrRX does not appear in the Tool Palette. How do I locate where Delphi thinks this is installed, and remove it, so I can reinstall the package?

• I am not able launch JNLP aaplications using "Java Web Start"?

  - by akjain

  Up until recently, I was able to launch/open JNLP files in Firefox using Java web start. Don't know what happened all of a sudden JNLP files stopped launching, a splash screen appears saying Java Starting... and then nothing happens. Even the Java Console in the browser and javacpl.cpl applet doesn't open. Tried all possibilities: removed all older version and installed the latest JRE (java version "1.6.0_17"), still it doesn't work. Done some googling for this problem, people suggested to start javaws.exe with -viewer option but same behavior (a splash screen appears saying "Java Starting..." and then disappears) The problem is that I don't know any place (logs etc.) to look for to see what is causing the problem. I am using WinXP SP3, and some of the screenshots below shows further info about my system. I can provide any other detail if required but please help me solve this problem. Update: Although this question is bit old, Following solution fixed above issue for me (indeed this was the actual cause)

• FileReference and HttpService Browse Image Modify it then Upload it

  - by user177787

  Hello, I am trying to do an image uploader, user can: - browse local file with button.browse - select one and save it as a FileReference. - then we do FileReference.load() then bind the data to our image control. - after we make a rotation on it and change the data of image. - and to finish we upload it to a server. To change the data of image i get the matrix of the displayed image and transform it then i re-use the new matrix and bind it to my old image: private function TurnImage():void { //Turn it var m:Matrix = _img.transform.matrix; rotateImage(m); _img.transform.matrix = m; } Now the mater is that i really don't know how to send the data as a file to my server cause its not stored in the FileReference and data inside FileReference is readOnly so we can't change it or create a new, so i can't use .upload();. Then i tried HttpService.send but i can't figure out how you send a file and not a mxml.

• Trying to Unit Test A Class That Makes DB Queries Using Hibernate And Can't Get Session Created...

  - by Jared Michaels

  I am trying to implement JUnit tests for a class that performs DB queries using Hibernate. When I create the class under test, I get access to the session through the factory by doing the following: InitialContext context = new InitialContext(); sessionFactory = (SessionFactory) context.lookup(hibernateContext); This works fine when I deploy this to JBoss 5.1. I am trying to figure out how to get this to work with my JUnit test. I keep getting an exception stating that I "Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial". I've searched high and low but haven't been able to find any information about what specifically I need to do to get this to work. I am not using Spring or any frameworks, just plain old Java and JUnit.
