  • Amazon EC2 Development Stack

    - by sirmak
    I want to use EC2 for some reasons and EC2 provides both windows and linux deployments, but linux is much cheaper (linux reserved instances are approx. %63-%85 price of windows ones and spot instances are %50 cheaper for linux). I need a type safe lang and mainstream platform and I prefer to use .net/c# stack (but not mono for some reasons), but in this situation java seems a better fit for the future (when ec2 instance counts begin to increase). So, is it worth to use .net ? best regards,

  • Protecting DLL's

    - by j-t-s
    Hi All Quite a few people have really taken interest in the dll's ivé sent them, and they're not the type that should be given away for free too often... I was just wondering, if I were to sell my components, user controls etc, how would I go about protecting them, in terms of ownership/encrypting code (if possible) etc.. What steps have you taken to help prevent people using yours without paying for them? Thank you very much! jt

  • JSONP context problem

    - by PoweRoy
    I'm using a javascript autocomplete () in a greasemonkey script. On itself it works correctly but I wan't to add JSONP because I want the data from another domain. The code (snippet): function autosuggest(url) { this.suggest_url = url; this.keywords = []; return this.construct(); }; autosuggest.prototype = { construct: function() { return this; }, preSuggest: function() { this.CreateJSONPRequest(this.suggest_url + "foo"); }, CreateJSONPRequest: function(url) { var headID = document.getElementsByTagName("head")[0]; var newScript = document.createElement('script'); newScript.type = 'text/javascript'; newScript.src = url +'&callback=autosuggest.prototype.JSONCallback'; //newScript.async = true; newScript.onload = newScript.onreadystatechange = function() { if (newScript.readyState === "loaded" || newScript.readyState === "complete") { //remove it again newScript.onload = newScript.onreadystatechange = null; if (newScript && newScript.parentNode) { newScript.parentNode.removeChild(newScript); } } } headID.appendChild(newScript); }, JSONCallback: function(data) { if(data) { this.keywords = data; this.suggest(); } }, suggest: function() { //use this.keywords } }; //Add suggestion box to textboxes window.opera.addEventListener('AfterEvent.load', function (e) { var textboxes = document.getElementsByTagName('input'); for (var i = 0; i < textboxes.length; i++) { var tb = textboxes[i]; if (tb.type == 'text') { if (tb.autocomplete == undefined || tb.autocomplete == '' || tb.autocomplete == 'on') { //we handle autosuggestion tb.setAttribute('autocomplete','off'); var obj1 = new autosuggest("http://test.php?q="); } } } }, false); I removed not relevant code. Now when 'preSuggest' is called, it add a script to the header and circumvent the crossdomain problem. Now when the data is received back 'JSONcallback' is called. I can use the data, but when 'Suggest' is I can't use the this.keywords array or this.suggest_url. I think this is because 'JSONcallback' and 'Suggest' are called in a different context. How can I get this working?

  • ASP.NET site sometimes freezing up and/or showing odd text at top of the page while loading, on load

    - by MGOwen
    I have various servers (dev, 2 x test, 2 x prod) running the same asp.net site. The test and prod servers are in load-balanced pairs (prod1 with prod2, and test1 with test2). The test server pair is exhibiting some kind of (super) slowdown or freezing during about one in ten page loads. Sometimes a line of text appears at the very top of the page which looks something like: 00 OK Date: Thu, 01 Apr 2010 01:50:09 GMT Server: Microsoft-IIS/6.0 X-Powered_By: ASP.NET X-AspNet-Version:2.0.50727 Cache-Control:private Content-Type:text/html; charset=ut (the beginning and end are "cut off".) Has anyone seen anything like this before? Any idea what it means or what's causing it? Edit: I often see this too when clicking something - it comes up as red text on a yellow page: XML Parsing Error: not well-formed Location: http://203.111.46.211/3DSS/CompanyCompliance.aspx?cid=14 Line Number 1, Column 24:2mMTehON9OUNKySVaJ3ROpN" / -----------------------^ If I go back and click again, it works (I see the page I clicked on, not the above error message). Update: ...And, instead of the page loading, I sometimes just get a white screen with text like this in black (looks a lot like the above text): HTTP/1.1 302 Found Date: Wed, 21 Apr 2010 04:53:39 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET X-AspNet-Version: 2.0.50727 Location: /3DSS/EditSections.aspx?id=3&siteId=56&sectionId=46 Set-Cookie: .3DSS=A6CAC223D0F2517D77C7C68EEF069ABA85E9392E93417FFA4209E2621B8DCE38174AD699C9F0221D30D49E108CAB8A828408CF214549A949501DAFAF59F080375A50162361E4AA94E08874BF0945B2EF; path=/; HttpOnly Cache-Control: private Content-Type: text/html; charset=utf-8 Content-Length: 184 object moved here Where "here" is a link that points to a URL just like the one I'm requesting, except with an extra folder in it, meaning something like: http://123.1.2.3/MySite//MySite/Page.aspx?option=1 instead of: http://123.1.2.3/MySite/Page.aspx?option=1 Update: A colleague of mine found some info saying it might be because the test servers are running iis in 64 bit (64bit win 2003) (prod servers are 32 bit win 2003). So we tried telling IIS to use 32 bit: **cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1 %SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i ** (from this MS support page) But iis stopped working altogether (got "server unavailable" on a white page instead of web sites). Reversing the above (see the link) didn't work at first either. The ASP.NET tab disappeared from our IIS web site properties and we had to mess around for an hour uninstalling (aspnet_regiis.exe -u) and reinstalling 32 bit ASP.NET and adding Default.aspx manually back into default documents. We'll probably try again in a few days, if anyone has anything to add in the meantime, please do.

I want to test out the following user scenarios Old version of Silverlight No Silverlight Cross browser In the past I have seen tools for uninstalling and installing different versions of Flash for this same type of testing. Is there anything like that for Silverlight? I know I can disable the plug ins but that is not the same IMHO TIA Pat

  • Delphi - Frac function losing precision.

    - by PeteDaMeat
    I have a TDateTime variable which is assigned a value at runtime of 40510.416667. When I extract the time to a TTime type variable using the Frac function, it sets it to 0.41666666666. Why has it changed the precision of the value and is there a workround to retain the precision from the original value ie. to set it to 0.416667.

  • How do I convert integers to characters in C#?

    - by Mike Webb
    I am trying to convert an index of 1 to 27 into the corresponding uppercase letter. I know that in C++ I could type this: char letter = 'A' + (char)(myIndex % 27); This same code does not work in C#. How can I accomplish this task in C#? EDIT: I'd rather not have to encode an enum or switch statement for this if there is a better mathematical solution like the one above.

  • Tool which can do both UML and ER Diagram

    - by Abhishek
    Hello, I have approval to buy one tool which can help programmers of my team to write better code. Most of my team members either do UML (.NET developers) or they do ER (database developers) Can you please recommend a tool for me which can do both of these type of diagrams? Please don't recommend Visio because my team already evaluated it and everyone disliked it as either a UML or ER diagram tool.

  • Distributed sequence number generation?

    - by Jon
    I've generally implemented sequence number generation using database sequences in the past. e.g. Using Postgres SERIAL type http://neilconway.org/docs/sequences/ I'm curious though as how to generate sequence numbers for large distributed systems where there is no database. Does anybody have any experience or suggestions of a best practice for achieving sequence number generation in a thread safe manner for multiple clients?

  • Is there a C# (.net) library similar to GNU readline?

    - by paul.moore.name
    I'm considering writing a console application in C# and I want to incorporate history, completion and command line editing features something like GNU readline (but not necessarily as extensive as that!) Is there an existing library for .net which provides this type of functionality? I guess one option would be to use interop services to call GNU readline. But is there a native option? Paul.

  • PHP script works fine until I send it a parameter from HTTPService in Flash Builder 4?

    - by ben
    I'm using a PHP script to read an RSS feed in my Flex 4 app. The script works when I put the url of the feed in the actual script, but I can't get it to work when I try to send the URL as a parameter from a HTTPService in Flex.

But for some reason It isn't. I know because when I compile I get errors about HINSTANCE not naming a type. Do I need to do anything else to make these defines available?
