• Flash Media Server dynamic file naming

  - by flying_tiger

  I'm trying to figure out most efficient/safe way to name recorded streams on FMS. The case is to get listing of recorded streams from the server (eg. rec_001, rec_002...) and dynamically add rec_003 filename to the new stream that is being recorded. I'm thinking about either using FMS File Object and put everything in array of files every time I start recording procedure or to create XML file that would serve as a database of file names. I'm searching for a solution efficient for MULTIPLE connections at a time and large amount of files. Which one of presented would be the best for this purpose? Or do you have any better suggestions of solving this problem?

• Backbone.js: How to utilize router.navigate to manipulate browser history?

  - by Xavier_Ex

  I am writing something like a registration process containing several steps, and I want to make it a single-page like system so after some studying Backbone.js is my choice. Every time the user completes the current step they will click on a NEXT button I create and I use the router.navigate method to update the url, as well as loading the content of the next page and doing some fancy transition with javascript. Result is, URL is updated which the page is not refreshed, giving a smooth user experience. However, when the user clicks on the back button of the browser, the URL gets updated to that of a previous step, but the content stays the same. My question is through what way I can capture such an event and currently load the content of the previous step and present that to the user? Or even better, can I rely on browser cache to load that previously loaded page? EDIT: in particular, I'm trying something like mentioned in this article.

• What causes Python "Interpreter not Initialized" error?

  - by ?????

  I'm now on my third full day this week of trying to get OpenCV to work with Python. (I have been trying on and off for the past 6 months). I get this error Python 2.7.1 (r271:86882M, Nov 30 2010, 10:35:34) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. dlopen("/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/readline.so", 2); import readline # dynamically loaded from /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/readline.so >>> import cv dlopen("./cv.so", 2); Fatal Python error: Interpreter not initialized (version mismatch?) and then it crashes (core dumps). python -v gives nothing after the dlopen. Any ideas from anyone who actually knows about this error?

• background picture for textview

  - by AndyAndroid

  Hi, I have a textview and a nine-patch image. Assigning this image in the xml editor to the tag "background" works as desired. Now I want to set this image dynamically in the coding, I thought myTextView.setBackgroundDrawable(mydrawable); would be the right thing to do. My png is in res/drawable. The API says that mydrawable needs to be an object of type drawable R.drawable.myninepatch is of type int. So my problem is that I have to convert from that int to a drawable somehow. Then I thought I can use a constructor NinePatchDrawable mydrawable = new NinePatchDrawable(); But I am again not able to construct such an object. Anyone an idea? Thanks.

• SQL Server (TSQL) - Is it possible to EXEC statements in parallel?

  - by Investor5555

  SQL Server 2008 R2 Here is a simplified example: EXECUTE sp_executesql N'PRINT ''1st '' + convert(varchar, getdate(), 126) WAITFOR DELAY ''000:00:10''' EXECUTE sp_executesql N'PRINT ''2nd '' + convert(varchar, getdate(), 126)' The first statement will print the date and delay 10 seconds before proceeding. The second statement should print immediately. The way T-SQL works, the 2nd statement won't be evaluated until the first completes. If I copy and paste it to a new query window, it will execute immediately. The issue is that I have other, more complex things going on, with variables that need to be passed to both procedures. What I am trying to do is: Get a record Lock it for a period of time while it is locked, execute some other statements against this record and the table itself Perhaps there is a way to dynamically create a couple of jobs? Anyway, I am looking for a simple way to do this without having to manually PRINT statements and copy/paste to another session. Is there a way to EXEC without wait / in parallel?

• Drupal: FileFields... internal server error

  - by Patrick

  hi, I've moved my drupal installation to new server and the website works. HOwever I get an "internal server error" for each file field in my nodes. In other words, images and videos are not loaded. In Firebug, Net Tab I can see they cannot be retrieved from the server because of "internal server error". The only thing I changed with respect to the previous installation is commenting the following 2 lines in .htaccess # Don't show directory listings for URLs which map to a directory. #Options -Indexes # Follow symbolic links in this directory. #Options +FollowSymLinks Is this the issue ? How can I solve this ? thanks

• Conditionally setting the font color of an item in a drop down box in JSF

  - by Greg

  I'm a newbie to web programming, so please bear with me. I am using JSF 1.2 and I want to conditionally set the color of the items in my drop down list. In other words, I have a collection of items that, along with a key and a value, also have a boolean property, warning, that is dynamically set by user action. I want the drop down to show all of the items, but those whose warning property is set to true should be displayed in red. I assume I have to extend the SelectItem class to add in the boolean property. How do I then conditionally set the color of the font of those items whose warning property is set to true in my JSP pages? Thanks in advance

• In Linux, how can I completely disregard the contents of /etc/ld.so.cache?

  - by BillyBBone

  Hi, For the purposes of prototyping a new set of shared libraries in a development sandbox (to which I don't have root access), I'd like to know how to execute a binary while completely overriding the contents of /etc/ld.so.cache, so that none of the system libraries get loaded. How can this be done? I have looked at mechanisms like setting the LD_LIBRARY_PATH environment variable or launching the program wrapped inside /lib/ld-linux.so, but these methods all seem to supplement the loading of libraries from /etc/ld.so.cache, but not override it completely. Help?

• Changing Dropdown based on Other Dropdown Menu

  - by Shaded

  I've seen a few questions like this, but mine is a bit more specific so I hope this isn't considered a repost. I am working on a website that is built with struts 2 and hibernate. I need to dynamically populate a drop down menu using data from a sql query based on an option selected in another drop down menu. So basically when the first option is selected I need to rehit the server and get the results from a query like SELECT column FROM table WHERE option = dropDownOption On top of that, I would really like to use ajax to only refresh the affected elements, however I'm really unfamiliar with ajax. I have jquery on this project and I found they have some ajax built in, but is this a good method for using it? any advice on this topic would be appreciated.

• Filter Warnings In Error List Windows In Visual Studio 2010

  - by Chuck Haines

  I just recently got the approval to upgrade our project from .NET 1.1. to .NET 4. I loaded up the project in Visual Studio 2010 and I've got it compiled and working. However as is to be expected there are over 3000 warnings I need to start looking at and handling. The problem is this solution has about 20 projects in it. So what I'd like to be able to do is filter the warnings on project. So I could say only show warnings for this project. Does anyone know if this is possible in Visual Studio 2010 or if there is an add-on I can add?

• How to use SSRS to retrieve HTML snippets with embedded images the easy way

  - by Ram

  I have a web-app that retrieves reports from our SSRS server dynamically - we hit a URL and out pops some HTML4.0 which I stuff into a div for the user to view. I recently tried adding a report that has an embedded image (in the RDL itself) and the image doesn't make it through. What does make it through is an IMG SRC reference back to the SSRS box but we do not allow end users to hit the SSRS box directly... users query the web-app and the web-app interacts with the SSRS service. There is an option to render in MHTML (note that we typically use rs:command=RenderHTML with rs:format=HTML4.0) - the blob returned appears to be valid MIME but does not seem friendly for stuffing into a DIV... am I missing something obvious? My next step is to parse the MIME, swizzle the references and stuff the whole thing back into the page but I feel like this is the hardway. What is the easy way to retrieve HTML snippet reports out of SSRS with embedded images?

• PrivateFontCollection fails on appharbor

  - by grennis

  I am trying to load a custom font (ttf file) and draw into an image with the Graphics object. This code runs fine locally: PrivateFontCollection fonts = new PrivateFontCollection(); string path = context.Server.MapPath("~/App_Data/Futura LT Bold.ttf"); if (!System.IO.File.Exists(path)) { throw new InvalidOperationException("Font file is not deployed: " + path); } fonts.AddFontFile(path); However when run on appharbor, the call to AddFontFile fails with the exception: System.ArgumentException: Font 'Futura LT Book' does not support style 'Regular'. at System.Drawing.Font.CreateNativeFont() at System.Drawing.Font.Initialize(FontFamily family, Single emSize, FontStyle style, GraphicsUnit unit, Byte gdiCharSet, Boolean gdiVerticalFont) at System.Drawing.Font..ctor(FontFamily family, Single emSize) at LumenboxWeb.Controllers.GalleryController.FontTest() in d:\temp\h5oqslma.udd\input\src\LumenboxWeb\Controllers\GalleryController.cs:line 59 at lambda_method(Closure , ControllerBase , Object[] ) at System.Web.Mvc.ActionMethodDispatcher.Execute(ControllerBase controller, Object[] parameters) at System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext, IDictionary`2 parameters) I have tried different fonts, and they all work locally, but none work on appharbor. Is it possible to load fonts dynamically on appharbor?

• Qt layout problem.

  - by Lukasz Lew

  I have a following Qt code: QVBoxLayout* box = new QVBoxLayout; label = new QLabel(); // will be set later dynamically box->addWidget (label); Text in label will be set later. The problem is that when label resizes, it resizes QVBoxLayout, and it resizes other neighboring widgets. I don't want to make a label or layout fixed width. Because I want them to resize with a whole window. Is it possible to tell a widget to take all the place that it has in a layout, but not more?

• What's the reason why core data takes care of the life-cycle of modeled properties?

  - by mystify

  The docs say that I should not release any modeled property in -dealloc. For me, that feels like violating the big memory management rules. I see a big retain in the header and no -release, because Core Data seems to do it at any other time. Is it because Core Data may drop the value of a property dynamically, at any time when needed? And what's Core Data doing when dropping an managed object? If there's no -dealloc, then how and when are the properties getting freed up?

• How to find (or generate) thousands of company names for test/demo purposes

  - by schefdev

  Ok, so this is rightfully a testing question more than a development question, but the two should go hand in hand :) So, I've got a system I'm building which includes business contact information. Pretty common no doubt. My test/demo database currently has randomly generated individual's names loaded (thanks to a handy IRS spreadsheet I found). This has worked great for internal testing and review purposes, but it looks really odd when shown to prospective customers. So.... Does anyone know where I can grab or find a listing of thousands of business names (address information too would be nice)? I've tried various online public information sources (e.g. EDGAR, and county based property records searches), but these all require me to manually stitch together the results in blocks of 50 names or so at a time. I could do this, but was really hoping for a search service or data store out there that had this type of information readily searchable and retrievable in very large batches. Thanks!

• Alternative to iframe using AJAX

  - by JCHASE11

  Hello. I have a music player swf embedded on an html page. Is there any way to have the music continuously play, even when the different html pages are loaded? When a link is clicked, the page is refreshed, also restarting the swf(music). If the site was AJAX driven, this wouldn't be a problem, but all my pages are static. I suppose I could put the entire body in an iframe, but there has to be a better option. Any ideas?

• Can I change the datsource of report model at runtime

  - by Manab De

  I've some adhoc reports developed on some report models which are published on Report Server (we're using SSRS 2008). Everything is running well. Now in our production environment we've near about forty (40) customers who have their own database (each have the same table structures and other database objects). Now the challenge is whenever a customer will log into the report server using windows authentication and trying to view those reports we need to get the SQL data from the proper database only. Reports are designed using the report model and each model has a valid data source which is connected to particular database. We can create forty separate data sources each will be connected to specific database. My question is, is there any way through which we can change the report model data source name dynamically or during runtime based on the customer name so that during execution of the report, SSRS would fetch the data from the correct database but not from any other database. Please help me.

• Assigning unsigned char* buffer to a string

  - by CPPChase

  This question might be asked before but I couldn't find exactly what I need. My problem is, I have a buffer loaded by data downloaded from a webservice. The buffer is in unsigned char* form in which there is no '\0' at the end. Then I have a poco xml parser needs a string. I tried assigning it to string but now I realized it would cause problem such as leaking. here is the code: DOMParser::DOMParser(unsigned char* consatData, int consatDataSize, unsigned char* lagData, int lagDataSize) { Poco::XML::DOMParser parser; std::string consat; consat.assign((const char*) consatData, consatDataSize); pDoc = parser.parseString(consat); ParseConsat(); } Poco xml parser does have a ParseMemory which need a const char* and size of data but for some reason it just gives me segmentation fault. So I think it's safer to turn it to string. Thanks in advance.
