  • .net - how to connect windows service with systray application

    - by razor
    I have a windows service that do something periodically. on user account runs systray application (written in C#) that communicate with windows service (thru .net remoting) and shows a status and some option to users. Everything works well beside that systray app uses 20-30MB of RAM ! it have to work in terminal environment, when 50 users login, only systray apps take 1GB of RAM ! and i don't have to add, that's wrong :) Is it possible to write .net systray application that will be small ? (1-2MB max?) or should I write it in c/c++? then, what kind of communication should I use between windows service (written in C#) and systray app ?

  • Spawning Process Never Finishes on ASP.NET Page

    - by Nissan Fan
    The code below spawns the process and sits forever, never finishing. It doesn't matter what process I run. If I use delegates it doesn't work either. It just hangs up in my dev and on the test enviornment. Also, if I use Shell with Wait it does the same thing. If I set wait to false in either approach it works just fine. It's ASP.NET 2.0 VB.NET DotNetNuke 4.0 on Windows Server 2003. I can't even phathom why this would hang up. UPDATE: It causes the CPU to throttle up but it's not running anything. It's like there's something weird going on in the threading. From: http://www.freevbcode.com/ShowCode.asp?ID=5879 Public Sub ShellandWait(ByVal ProcessPath As String) Dim objProcess As System.Diagnostics.Process objProcess = New System.Diagnostics.Process() objProcess.StartInfo.FileName = ProcessPath objProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden objProcess.Start() 'Wait until the process passes back an exit code objProcess.WaitForExit() 'Free resources associated with this process objProcess.Close() End Sub

  • ASP.NET MVC, JSON & non JavaScript clients

    - by redsquare
    I need to ensure that an application I am developing is accessable and also works with JavaScript turned off. I just need a pointer to assist with the following. I had 3 'chained' select boxes and I wanted JavaScript enabled clients to have a nice Ajax experience. I can easily write the required functionality to populate the chained boxes on the change event of the preceeding select using jQuery and JSON with a WCF service. However what about the non JavaScript client? Would I wrap a submit next to the select and place these inside their own form to post back with a certain action or different querstring parameter? Can the same controller give me a partial JSON response as well as feeding the full HTML response. Can anyone point me to a good demo that utilises both JSON and normal HTTP posts to produce the same result in ASP.NET MVC. All ASP.NET MVC demo/examples I see forget about the non JavaScript enabled client.

  • ASP.NET JavaScript File Embeded In DLL With GZIP

    - by Lee Hesselden
    We have several fairly large JavaScript files embedded into a single script resources DLL. This is then consumed by multiple projects by way of a reference and page includes via the ASP.NET script manager. This keeps things nice and neat within our ASP.NET pages and requires very little work to integrate into new projects. The problem is that some of these script files are quite larger (approx 100KB) and take time to download. By running minify on them before embedding this is reduced down a lot (around 70KB) but not enough. What we would like to do is GZIP the files before they are embedded. However, just gzipping the files causes syntax errors as the content is not unzipped. There is a content type "text/javascript" applied in AssemblyInfo when the resource is embedded but we can't find a way to specify content-encoding. Is there any way to make this work without having to write a httpmodule/handler (which would mean changing the config for all consuming projects)?

  • Navigating from VB.NET code to C# code problem

    - by user181218
    Hi, There seemes to be a consistent problem with the following situation: Say you have a VS2008 solution, consisting of a (say console) application written in vb.net, and a class library written in c#. The application references the class library project. This, of course, complies and works well. However, when you right-click (in the vb.net application code) a function prototype/object type defined in the class library, and select "Go to definition", the object browser opens providing you with the the list of methods available for the class the class library consists of. BAD. However, if you try to do the same when both the application and cl are in c#, this works just fine and you navigate driectly to the relevant function/class.GOOD. Known issue? Solvable?

  • Using Jquery and Ajax in ASP.NET

    - by xkcd
    I am using ajax and jquery to load contents into a div. My jquery looks like this $("a.trigger").click(function() { $.ajax({ type: "POST", url: "GetStuff.aspx", data: "id=0", success: function(response){ $("#contentDiv").html(response); } }); }); In GetStuff.aspx I would like to write some asp.net html controls like private void Page_Load(object sender, System.EventArgs e) { Response.Expires = -1; Response.ContentType = "text/plain"; Response.Write("<asp:Label id=\"label1\" runat=\"server\" text=\"helloworld\"/>"); Response.End(); } However the label does not appear on the page. I tried to put the asp:Label in my aspx file like this <%@ Page Language="C#" Inherits="Untitled.GetStuff" %> <asp:Label id="label12" runat="server" text="helloworld2"/> It also does not work. How can I get asp.net html controls to show up?

  • Actors in Scala.net

    - by weijiajun
    I have recently completed some study of erlang, and was intrigued by scala for its feature set and the ease of interpolating with java (and possibly .net) applications. I am finally studying actors and was wondering if there is an actor mechanism that currently works in .net. I have looked at the libararies that come down with sbaz and have found that there is a scala.Concurrent but no scala.actors.Actor. I tried to use the scala.Concurrent.Channel but was unable to use the ! to send messages. I was just wondering if this is something that is currently available and if so how do you go about setting it up.

  • Aldon and .Net Development

    - by David Stratton
    I'm looking for feedback from .Net developers who have experience with Aldon as a lifecycle management platform. We're seriously considering using Aldon for lifecycle management including source control, automated builds, etc. I know there are a lot of other options out there, but ours is primary an AS/400 shop (with AS/400 programmers outnumbering .Net developers 6 to 1), and Aldon is used already by our iSeries team. The benefit we're looking for is having one lifecycle management suite. Basically, I'm looking for opinions from people who have used Aldon and another set of tools (perhaps TFS, or a combination of SVN, Cruise Control, etc). If you've worked with both, do you have a recommendation on whether this is a good idea, or a bad idea? It's obviously a big choice, so any feedback would be helpful.

  • DNS Lookup in simple C#/asp.net ajax call is extremely slow

    - by Ryan
    I'm running this out of the VS 2008 debugger on Windows 7, running .Net 3.5. The idea was to make all ajax requests with jQuery only, rather than .net, following some tutorials online. Default.aspx - HTML page, jquery triggers method in Default.aspx.cs http://pastebin.com/pxBvKA2H Default.aspx.cs - C# Webform, just defines a GetDate fuction, which only returns a string for now (trying to eliminate any possible issues) (can only post one hyperlink...) pastebin.com/pnHn50hu The ajax query takes longer than it should. Profiling with firebug revealed that it took 1.03 ms. 1s DNS Lookup | 26ms Waiting | 1ms Receiving EDIT: It continues to take the same set of times if you continue to click and resubmit the request. Is there anything I can do to cut down on the DNS Lookup time / what did I do wrong? Thanks for any help.

  • Using ASP.NET Session for Lifetime Management (Unity)

    - by Sigray
    I am considering using Unity to manage the lifetime of a custom user class instance. I am planning on extending the LifetimeManager with a custom ASP.NET session manager. What I want to be able to do is store and retrieve the currently logged in user object from my custom classes, and have Unity get the instance of User from the session object in ASP.NET, or (when in a Win32 project) retrieve it statically or from the current thread. So far my best solution is to create a static instance of my Unity container on startup, and use the Resolve method to get my User object from each of my classes. However, this seems to create a dependency on the unity container in my other classes. What is the more "Unity" way of accomplishing this goal? I would like to be able to read/replace the current User instance from any class.

    Where can I get code example of using google docs with asp.net mvc? I need to upload documents and make it possible for people to download them. Also would be just great to make it possible to see the documents like I see them on google docs and be able to edit (probably use iFrame) but would like to get working example or some tips to get started. Code pieces are greatly appreciated, upvoted and marked as answer ;-), but I~ll be enought with a good starting points. P.S. I~m aware of google have docs for their api :-). Just looking for other places to start from. Codeproject article or github repo of api used with asp.net mvc would be the best.

  • ASP.NET - Exception logging approach for concurrent user scenario

    - by Whiskey-Tango-Foxtrot
    I am involved in designing a asp.net webforms application using .NET 3.5. I have a requirement where we need to log exceptions. What is the best approach for exception handling, given that there would be concurrent users for this application? Is there a need or possibility to log in exceptions at a user level? My support team in-charge wants to have a feature where the support team can get user specific log files. To give you a background, this application is currently on VB 6.0 and we are migrating it along with some enhancements. So, today the support personnel have a provision to get user specific log files.

  • Back Button gets Disabled on IE 7,8 for an ASP.NET site

    - by timeitquery
    In an ASP.NET 3.5 website we are noticing that the back button is not working properly. If the user does several postbacks (say 10 times), and than starts pressing back button - the back button gets disabled before the user gets through all the pages. The site does not use AJAX.net. I can reproduce the issue on IE 7 and 8 almost always. The problem seems to be with some sort of limit IE has on History Cache for a given tab/instance. In the tests I did the post request to the server are large - around 83k, and the responses are are round 300k. It seems that with these request sizes the history does not hold more than 4 items. The moment I get to the 5 post, the first item i had selected is dropped.

  • ASP.NET Controls Not Recognized

    - by Liam
    I just installed the release version of Visual Studio 2010, and it looks like there's something wrong with the standard ASP.NET server controls. When I create a basic server control, such as a TextBox, the editor underlines it in green and says (I also get no intellisense for ASP.NET controls): Element 'TextBox' is not a known element. This can occur if there is a compilation error in the Web site, or the Web.config file is missing. The web site builds fine, and the Web.config file is not missing: <?xml version="1.0"?> <configuration> <system.web> <compilation debug="false" targetFramework="4.0" /> </system.web> </configuration> The controls work just fine in the code-behind, and they function correctly when I run the site. Is there some configuration problem here?
