  • trying to decide between asp.net and jsp

    - by Amir
    Hey Guys, I am wondering if anyone can shed some lights on the situation. I am about to start a project and trying to figure out what solution is best to go with asp.net or java jsp pages I have personally worked alot with .net and am really happy with the framework and Visual studio as IDE I find it easy to work with and there is a massive community support behind .net, i can get alot done quickly I have not every written anything use java jsp, there will be a learning curve here , so my experience is limited here. however after seeing jira i am very impressed with its capabilities, it has changed alot since the old days ( java 1.2 ) that i used to work with, and the fact that it runs under linux is a huge plus, so i am trying to decide is the learning curve, worth the price ? so given the situation above what would you recommended? Thanks, Amir

That is, in the window shown for the "Choose items", the controls are't anutomatically added to the list, as before. What should I do?

  • Rewriting VB.NET Lambda experession as a C# statement

    - by ChadD
    I downgraded my app from version 4 of the framework to version 4 and now I want to implement this VB.NET lambda function statement (which works on 3.5) Dim colLambda As ColumnItemValueAccessor = Function(rowItem As Object) General_ItemValueAccessor(rowItem, colName) and rewrite it in C#. This was my attempt: ColumnItemValueAccessor colLambda = (object rowItem) => General_ItemValueAccessor(rowItem, colName); When I did this, I get the following error: Error 14 One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll? C:\Source\DotNet\SqlSmoke\SqlSmoke\UserControls\ScriptUserControl.cs 84 73 SqlSmoke However, when I downgraded the app from version 4.0 of the framework to 3.5 (because our users only hae 3.5 and don't have rights to install 4.0). when I did this, the reference to "Microsoft.CSharp" was broken. Can I rewrite the VB.NET command in C# using syntax that is valid in C# 3.5 as I was able to in VB.NET? What would the syntax be?

  • how to invoke onclick function in html from vb.net or C#

    - by vbNewbie
    I am trying to invoke the onclick function in an html page that displays content. I am using the httpwebreqest control and not a browser control. I have traced the function and tried to find the link it calls but looking at the code below I tried inserting the link into the browser with the main url but it does not work. <div style="position:relative;" id="column_container"> <a href="#" onclick=" if (! loading_next_page) { loading_next_page = true; $('loading_recs_spinner').style.visibility = 'visible'; **new Ajax.Request('/recommendations?directory=non-profit&page=**' + next_page, { onComplete: function(transport) { if (200 == transport.status){ $('column_container').insert({ bottom: transport.responseText }); loading_next_page = false; $('loading_recs_spinner').style.visibility = 'hidden'; next_page += 1; if (transport.responseText.blank()) $('show_more_recs').hide(); } } }); } return false; Any ideas would be deeply appreciated.

  • Constructing an object and calling a method without assignment in VB.Net

    - by mdryden
    I'm not entirely sure what to call what C# does, so I haven't had any luck searching for the VB.Net equivalent syntax (if it exists, which I suspect it probably doesn't). In c#, you can do this: public void DoSomething() { new MyHelper().DoIt(); // works just fine } But as far as I can tell, in VB.Net, you must assign the helper object to a local variable or you just get a syntax error: Public Sub DoSomething() New MyHelper().DoIt() ' won't compile End Sub Just one of those curiosity things I run into from day to day working on mixed language projects - often there is a VB.Net equivalent which uses less than obvious syntax. Anyone?

  • asp.net mvc deployment

    - by Casey
    I've been dealing with a legacy asp.net 2.0 web site that was originally setup to deploy everything (source uncompiled) to the target server. I've been looking at doing some major upgrades and want to move to asp.net mvc. I'm coming from mostly a Java background where we typically deploy everything inside of a Web ARchive (war file) and the application server takes it from there. Is there a similar concept in the .net world? Right now in my mvc test app, I just put the compiled code into the deployed bin folder and the rest of the script/view files there as well. From what I have been reading it seems that most use the Publish feature of VS.

  • Asp.net 4.0 site fails because no handler mapped with Classic appPool

    - by AndyV
    When I create a Asp.net app and flip the appPool to "ASP.NET v4.0 Classic" it fails with the following error: HTTP Error 404.17 - Not Found The requested content appears to be script and will not be served by the static file handler. After some searching it seems to be the handler not mapping correctly for the Classic mode but I can't find out where or how to fix that. I have the full .Net 4.0 install with VS2010 and the app works fine if I flip the appPool to Integrated. Also, it's a Windows 7 machine (I'm having the same problem on a Vista box). Thanks in advance. Andy

  • How to automatically include generated source files into a C# project in Visual Studio?

    - by Charles Prakash Dasari
    I have a situation where I need to generate a bunch of C# code files in a prebuild step of a project and include the generated files into the current project for compilation. Is there a way to do this cleanly without having to muck with the project file every time the prebuild step is run? My solution should work for both IDE based build and a Team Build based on MSBuild. Since both are MSBuild based, I suspect there won't be much difference; but wanted to call it out. Any help is greatly appreciated, thanks!

  • ComboBox's Selected Value Changed On Lost Focus in VB.NET

    - by tunwn
    I have a datagridview(dgv) with a DataGridViewComboBoxColumn(colLocation) colLocation.AutoComplete = False colLocation.HeaderText = "Stored to" colLocation.DataSource = DB.getLocation() colLocation.DisplayMember = "description" colLocation.ValueMember = "id" I added the colLocation to dgv. "descirption" contains Unicode characters. I can see the comboBox correctly and choose the item. The problem is when the comboBox lost the focus, the value is changed to first item of the comboBox. Any suggestion? Updated: I found out that the ComboBox doesn't change the data when the DisplayMember is in English characters. It changes only when the DisplayMember is in Unicode chracter. Any idea for how could solve this? – tunwn 0 secs ago

  • ASP.Net Custom Field From Query In DataSet

    - by boruchsiper
    I added a new query to a table adapter in a DataSet. This query adds another field to the query whcih is a sum from another table. Here is the full query: SELECT (SELECT COUNT(donationID) AS Expr1 FROM Donations AS da WHERE (dn.donorID = donorID)) AS Count, Solicitor, address1, address2, city, companyName, country, donorID, email, first, last, phoneHome, phoneMobile, phoneWork, state, webURL, zip, (select sum(amount) from Donations as dna where dna.donorID = dn.donorID) as SumDonations FROM Donors AS dn order by last The new field is represented in the last part of the query: (select sum(amount) from Donations as dna where dna.donorID = dn.donorID) as SumDonations I can preview the data in the xsd but the last field "SumDonations" is not showing up as a field I can add to my gridview. I rebuilt the website but no luck. What am I missing?

  • ASP.NET MVC on IIS6

    - by Seb Nilsson
    Where can I find some good pointers on best practices for running ASP.NET MVC on IIS6? I haven't seen any realistic options for web-hosts who provide IIS7-hosting yet. Mostly because I don't live in the U.S. So I was wondering on how you best build applications in ASP.NET MVC and make it easily available to deploy on both IIS6 and IIS7. Keep in mind that this is for standard web-hosts, so there is no access to ISAPI-filters or special settings inside IIS6. Are there anything else one should think about when developing ASP.NET MVC-applications to target IIS6? Any functions that doesn't work? UPDATE: One of the bigger issues is the thing with routes. The pattern {controller}/{action} will work on IIS7, but not IIS6 which needs {controller}.mvc/{action}. So how do I make this transparent? Again, no ISAPI and no IIS-settings, please.

  • Managing multiple .NET languages in a web application

    - by tomfanning
    I am part of a development team building a new ASP.NET 3.5 web application. Two of us are C# coders, and the other is a VB.NET coder. I know that we can mix languages on a per-project basis, and one can build classes in one language that inherit from classes written in the other language in a different project (which we are already doing), but I can see us getting into a situation where we might well end up with cyclic dependencies between our various project DLLs. Other than simply having a high number of projects (more seperation of concerns into more libraries), how have you managed this situation on your own projects? Note - I believe this question to be different enough from the only similar match I could find (this one) on the basis that we are not wanting to use different languages in order to take advantage of their specific features per se, but rather to make use of what developer resource is available to us (i.e. one dev just happens to be VB.NET only).

  • Visual Studio 2010 isn't building before a run when there are code changes. It was doing working yes

    - by jamone
    I've been using using F5 (Start Debugging) for years to build the code (if its out of date), and then debug. This was working on VS 2010 also, however today it just start debugging without a build. Say I do a clean on the project, and then hit F5 instead of building it so it can run it throws an error message saying that the exe doesn't exist to run. How do I make it build first? What could have changed?

  • Visual Studio Question: When doing a compile/debug is VS suppose to delete existing files in the bin

    - by Greg
    Hi, Q1 - When doing a compile/debug is VS suppose to delete existing files in the bin\debug area? (for VS2008) if no then can I ask please: Q2 - My winforms checks for existance of a sqlite.db3 file and creates it if it needs to (programmatically). If the behavior I wanted was that each Compile/Debug I do is for the target Debug area to be clear, so that the program would exercise the code that builds the database file, how would I organise this? thanks

  • Python Django vs ASP.NET MVC

    - by eddyc05
    Hey guys ! i'm fairly new at web development scene and i was wondering if you guys can help me break up the pros and cons of using python django vs asp.net mvc besides the maturity level of its framework. I have intermediate experience with JAVA. As of right now, i'm leaning towards python but i just wanted to make sure i am making the right choice. I find myself limited with books available on asp.net web developments. I am aware that there is the storefront example on the official asp.net site. However, that tutorial was a little hard for me to follow. I've done a research around and was hoping python could be my next available choice. There are more tutorials available online for python anyways. What do you guys think??

  • Downloading a file in ASP.NET (through the server) while streaming it to the user

    - by James Teare
    My ASP.NET website currently downloads a file from a remote server to a local drive, although when users access the site they have to wait for the server to finish downloading the file until they can then download the file from my ASP.NET website. Is it possible to almost stream the download from the remote website - through my ASP.NET website directly to the user (a bit like a proxy) ? My current code is as follows: using (var client = new WebClientEx()) { client.DownloadFile(downloadURL, "outputfile.zip"); } WebClient class: public class WebClientEx : WebClient { public CookieContainer CookieContainer { get; private set; } public WebClientEx() { CookieContainer = new CookieContainer(); } protected override WebRequest GetWebRequest(Uri address) { var request = base.GetWebRequest(address); if (request is HttpWebRequest) { (request as HttpWebRequest).CookieContainer = CookieContainer; } return request; } }

  • Best Template Engine for ASP.NET MVC

    - by OnesimusUnbound
    I am exploring ASP.NET MVC and I wanted to add jQuery to make the site interactive. I used StringTemplate, ported to .Net, as my template engine to generate html and to send JSON. However, when I view the page, I could not see it. After debugging, I've realized that the $ is used by the StringTemplate to access property, etc and jQuery uses it too to manipulate the DOM. Gee, I've looked on other template engines and most of them uses the dollar sign :(. Any alternative template engine for ASP.Net MVC? I wanted to retain jQuery because MSFT announced that it will used in the Visual Studio (2008?) Thanks in Advance :)

  • How to best integrate HTML/design with C# code in ASP.Net or ASP.Net MVC?

    - by LuftMensch
    We're working on a new ASP.Net site. The last major site we did was in classic ASP--the procedure we used there was to have the HTML completed first, then "bring it to life" with the ASP code. In the ASP.Net world, how does this work? I.e. how do the designers do their work if much of the mark-up is actually being generated by the server controls? We are also looking at ASP.Net MVC as a potential lightweight alternative. Would be very interested to know what was worked best for people in both scenarios in terms of working with the designers and integrating their work with the code.
