  • Java io ugly try-finally block

    - by Tom Brito
    Is there a not so ugly way of treat the close() exception to close both streams then: InputStream in = new FileInputStream(inputFileName); OutputStream out = new FileOutputStream(outputFileName); try { copy(in, out); } finally { try { in.close(); } catch (Exception e) { try { // event if in.close fails, need to close the out out.close(); } catch (Exception e2) {} throw e; // and throw the 'in' exception } out.close(); }

  • Visual Studio 2010 Database Project does not understand Schema Names anymore?

    - by Xenan
    I just tried to upgrade a Visual Studio 2008 Database project to VS2010 and actually it is quite a mess. Hundreds of warnings, all unsolved references. It seems to boil down to Visual Studio not to understand Schema Names (aka Ownership) anymore. For example, the standard dbo schema: [$(MyDataBase)].dbo.MyTable is fine but: [$(MyDataBase)].myschema.MyTable gives an unsolved reference. It did work in VS2008. Also the abbreviation for dbo, the double dot: [$(MyDataBase)]..MyTable Doesn't work anymore. In the project property windows I restored the references to the correct servers (which were lost after the conversion) but that didn't help. This seems pretty basic but I don't have a clue how to solve this. Any help is appreciated.

  • Can GhostScript run in Medium Trust

    - by SkippyFire
    I am using GhostScript to generate some thumbnails of PDF pages in an ASP.NET application. I have it wrapped in this library called GhostScriptSharp that just uses DllImport to call methods in the GhostScript DLL. It looks like this wont work on a medium trust hosting environment, either because of the fact that it is calling unmanaged code, or that it looks like the library is creating files all over the place (outside my virtual directory). I ran Process Monitor and saw it trying to Read, QueryNameInformationFile, CreateFile and QueryStandardInformationFile in places like: C:\WINDOWS\system32\Halftone\Default or C:\gs\gs8.63\lib\Halftone\Default or C:\gs\font\Halftone\Default Any ideas about whether this is "fixable" to run in medium trust? If I can't use GhostScript, is there another free/open source library that WILL work in Medium trust?

  • Add dynamic URL (or button) to each node in Drupal

    - by Bryan Folds
    I've used CCK to create a 'Travel Offer' content-type which basically just lists the details for a travel package. My question is how to have a button or link on each node (when the user views it) that will link to a url that includes the title of the current node (eg: example.com/requestQuote/Title_Of_This_Node). I haven't implemented my system yet so I am free to change the content-type to include a button field or something like that...

  • Button with image and loading element id when clicked

    - by Diego Correa
    Hello guys, I've made an application that makes full use of ajax, and what I need to do is: I want a button with a description + image that when clicked is disabled and instead of the original image in the button, appears the ajax loading element id inside the button. And when the ajax loading is complete, the original image of the button returns to the normal. Is there any good source on how to do something like this? What do you guys suggest?

  • Execute javascript in PHP

    - by Andreas Bonini
    I'm generating your typical Web 2.0 HTML page with PHP: it contains a lot of <script> tags and javascript code that will substantially change the DOM after the load event. Is there a way to get the final HTML code directly from PHP, without opening the page with any browser? For example, let's say the HTML for the page is (it's just an example): <html> <head> <script>...the jquery library code...</script> <script>$(document).ready(function() { $("body").append("<p>Hi!</p>");</script> </head> <body> </body> </html> This HTML is saved in the $html PHP variable. Now, I want to pass that variable to some function that will return $result = <html>....<body><p>Hi!</p></body></html>. Is this possible?

  • Deep clone utility recomendation

    - by Supowski
    Is there any utility for deep cloning for java collections: Arrays Lists Maps NOTE: prefer some solution without usage of serialization, but with use of Object.clone() method. I can be sure that my custom object will implement clone() method and will use only java-standard classes that are cloneable...

  • Render SSRS .RDL to PDF and just open it.

    - by FelipeFiali
    I tried to be the most descriptive I could. Ok, so since I've never done anything like this before, I guess it's better to ask before starting at all to just don't get the whole process wrong. We have a report that has to be called from an ASP.NET application, it could be a simple button. Through the code-behind, I gotta pass in a paramater, render the report, and don't save it anywhere, just open it to the user, as a .pdf file so he could save or print it. So please, give me links or tips, I'm reading MSDN documentation right now... If you have any suggestion on other technologies, as for the report, I'd like to hear it, but it has to be called from ASP.NET. Thanks in advance!

  • Compression without Mod_Deflate

    - by pws5068
    Greetings all, After running tests with Google PageSpeed, I believe my site could really benefit from compressing js/html/css/php files. Unfortunately, my host (Host Gator) does not support Mod_Gzip or Mod_Deflate. I was able to enable php compression through the ini file. Is there another way to serve compressed files to browsers that support them, in a manner similar to Mod_Deflate?

  • can router configuration cause decreasing of download rate?

    - by behrooz
    My download speed got crazy since I changed the router's IP. But nothing got fixed after doing a factory reset. The speed was 1024 kb/s (128 kB/s) but it is 200kb/s (max) right now. I mean it works good if a request is small (i.e. a HTTP request) but it gets slow if a request has a big response. Help me please. (It is three days I'm downloading VS2010.)

  • Do DBA’s not desire sleep?

    - by drsql
    Or any support people for that matter.  I constantly hear people having to support this, support that, wearing the “beeper”, etc etc.  But these people do seemingly love what they do, because I hear this on “non-essential” communications channels, like Twitter, SQL Saturday conversations, etc.  These are people who are doing what they do because they like it. I have to be honest with you though, about the second time I was awakened by a beeper with the same problem I would be outraged....(read more)
