  • What's the right way to communicate between 2 or more .Net applications running on a same computer w

    - by Ivan
    If my applications run on a same computer or even on different computers in a same LAN and need intense and quick communication, it seems illogical for me to use text-encoded web services and HTTP. I could possibly use IP/TCP/UDP sockets and invent my own protocols, but believe there is a standard way for .Net applications to send/receive object instances (and, maybe, even sharing an object by reference?). Can you tell me what's that standard way? I am only interested in .Net Framework 4 applications and don't need to support legacy frameworks.

  • Elmah and 404s under IIS6

    - by tomfanning
    Just wondering if it's possible to get Elmah to log 404s that aren't picked up by the ASP.NET framework - i.e. the 404s that IIS spots and replies to. Presumably this would involve some kind of entry in IIS - web site properties - Custom Errors tab. Can't find any reference on how to do this.

  • How to drop a primary key using ActiveRecord migrations

    - by knoopx
    Due to a mistake I forgot to add :id => false to a has_many :trough table creation migration. Now I reverted the association back to a has_and_belongs_to_many and ActiveRecord throws an exception complaining about the presence of the primary key. I couldn't find any reference on the ActiveRecord documentation so, do you know if there is any standard, clean way of doing it?

  • Stuck on an ASP.NET/WCF WSDL Parsing Error

    - by Vaccano
    I have a WCF Web Service that my ASP.NET app uses. It has been working fine for quite some time. I just added in a Dev Express Grid (and the Dev Express DLLs) and a new page that uses them and now I am getting parsing errors on the WSDL. But the weird part is that it works fine on my machine but fails on the web server machine. (Both are connecting to the same web services WSDL.) Here is the error message I am getting: Server Error in '/MyWebAppWebDev' Application. -------------------------------------------------------------------------------- Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Reference.svcmap: Failed to generate code for the service reference 'MyWebAppService'.

  • Programmatically add IP(s) or domain(s) to Relay Restrictions in SMTP Virtual Server on IIS 6

    - by RJ
    I have been given a task to create an admin page to programmatically add IPs or domains to a SMTP Relay Restrictions using C#. I spent some time researching this since yesterday and finally traced this down to a few posts on several website that use the System.DirectoryServices.DirectoryEntr class. Using the examples I found, I can add or deny IPs or domains under Connection control but not Relay Restrictions. What would be the commands in C# to add IPs to the Relay Restrictions? Below is a pic of the GUI in IIS for reference.-

  • Selecting a column that is also a keyword in MySQL

    - by randall123
    For some reason, the developers at a new company I'm working for decided to name their columns "ignore" and "exists". Now when I run MySQL queries with those words in the where clause, I get a syntax error; however, I can't seem to figure out how to reference those columns without running into an error. I tried setting them as strings, but that doesn't make any sense. Help? Also, is there a term for this kind of mismatch?

  • JavaScript setInterval loop not holding variable

    - by Ryan
    Here is my code: var showNo = 1; window.setInterval(function() { console.log(showNo); if(showNo === 1) { var nextNo = 2; } else if(showNo === 2) { var nextNo = 3; } else if(showNo === 3) { var nextNo = 4; } else if(showNo === 4) { var nextNo = 5; } else if(showNo === 5) { var nextNo = 1; } else { var showNo = 1; var nextNo = 2; } var showNo = nextNo; }, 500); My question is, why is the showNo variable not holding when the setInterval loop starts? The console displays 'undefined' in the above example. This may be a simple question, but I am trying to teach myself query and this has me stuck.. Any answers would be great. Thanks.

  • Gratuitous use of System.Runtime.Serialization attributes?

    - by rasx
    Is there any cost/drawback (apart from typing too much) to adorning a class with System.Runtime.Serialization attributes (like [DataContract]) such that it can be used locally as a direct reference to a desktop Client project or as a type for a WCF service? The goal here is to write a data-tier class that can be used in both rich client (WPF) and Web scenarios. My data classes will be in a project that is separate from Client and WCF (*.svc code-behind) code. Is this a valid attempt to reuse code?

  • How would I set up this enum to return the image I want?

    - by Justen
    I'm trying to set up this enum so that it has the ability to return the correct image, though I'm struggling with a way to incorporate the context since it is in a separate class. public enum CubeType { GREEN { public Drawable getImage() { return Context.getResources().getDrawable( R.drawable.cube_green ); } }; abstract public Drawable getImage(); } The error I'm getting is: Cannot make a static reference to the non-static method getResources() from the type Context

  • Failed opening 'SiteTest: Firefox.php' when running Yii Functional Test

    - by Phelios
    Warning: include(): Failed opening 'SiteTest: Firefox.php' for inclusion ... \yii\framework\YiiBase.php on line 418 Yii v1.1.10 PHPUnit v3.6.10 PHPUnit_Selenium v 1.2.6 I get this error when trying to run the example on the book "Agile Web Development with Yii 1.1 and PHP5" I kind of feel that there is a problem with the phrase SiteTest:, it shouldn't be there. But, how do I fix this? UPDATE (SOLVED): Apparently, the problem is not the warning shown above, but there is another error down the road. It says that "curl_init()" is undefined. I already enabled the php_curl extension, but the PHP from CLI is not using the same .ini file as the apache one. So, after I enabled the php_curl in the CLI version of the ini, it works fine now (still giving the warning, but the test is running).

  • Security of WCF endpoints

    - by Matt
    For the sake of argument, lets say that I've got a basicHttp WCF service. Besides implementing authentication (login/logout methods), what is stopping someone from just cracking open Visual Studio, adding a web reference to my website's service, and then playing playing around with my service? I'm not familiar with a method of stopping someone from doing this. The idea of someone downloading all of my Data/Operation contracts and then start playing around is keeping me up at night, and I like my sleep!

  • Ruby module_function, invoking module's private method, invoked in class method style on module shows error

    - by Jignesh
    test_module.rb module MyModule def module_func_a puts "module_func_a invoked" private_b end module_function :module_func_a private def private_b puts "private_b invoked" end end class MyClass include MyModule def test_module module_func_a end end Invoking module function from class c = MyClass.new c.test_module Output 1: $ ruby test_module.rb module_func_a invoked private_b invoked Invoking module function on module in class method style ma = MyModule.module_func_a Output 2: module_func_a invoked test_module.rb:5:in `module_func_a': undefined local variable or method `private_b' for MyModule:Module (NameError) from test_module.rb:31 As can be seen from the Output 1 and Output 2 when including the module in a class, no issue occurs when a module's private method gets invoked from a module function while in case when directly invoking the module function on the module in class method style the module's private method, invoked from module function, is not found. Can anybody make me understand the reason behind above behavior and whether invoking module function (which in turn invokes module's private method) on module in class method style is possible or not? If possible, then what rectifications are required in my code to do the same? Thanks, Jignesh

  • "[object Object]" passed instead of the actual object as parameter

    - by Andrew Latham
    I am using Heroku with a Ruby on Rails application, and running from Safari. I have the following Ajax call: $.ajax({ type : 'POST', url : '/test_page', data : {stuff: arr1}, dataType : 'script' }); arr1 is supposed to be an array of objects. There's a console.log right before that, and it is: [Object, Object, Object, Object, Object, ...] However, I got an error on the server side when I made this ajax call. The logs showed 2012-10-01T03:13:34+00:00 app[web.1]: Parameters: {"stuff"=>"[object Object]"} 2012-10-01T03:13:34+00:00 app[web.1]: WARNING: Can't verify CSRF token authenticity 2012-10-01T03:13:34+00:00 app[web.1]: NoMethodError (undefined method `to_hash' for "[object Object]":String): 2012-10-01T03:13:34+00:00 app[web.1]: Completed 500 Internal Server Error in 1ms I'm unable to replicate the error. It's really confusing to me - what would cause that string to sometimes be passed to the server instead of the object?
