How Does Compiling Happen Only For The First Time In Project-less Development

Jan 16, 2011

I read these words in a book:

Projectless development simplifies debugging: When creating a web project, you must recompile the entire application when you change a single page. With projectless development, each page is compiled separately, and the page is only compiled when you request it for the first time.

How does compiling happen only for the first time in projectless development?

Should it recompile every time I run the page to reflect the new code I wrote it?

Validation Didn't Happen On 2nd Time Around?

Jan 18, 2010

I have a Page_load sub with the following:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Request.ServerVariables("SERVER_PORT") = 80 Then
Dim strSecureURL As String
[code]....

The validation load in this page worked on the first click of btnDonation, if I don't change anything and click the btnDonation again, it automatically go to my confirm page. Instead, I want it to continue to check for requiredFieldsOK(). Note that if I fill in one of the missing required fields, the validation will work.

My question is: How can I continue to check for requiredFieldsOK() even if user didn't fill out any additional information?

Visual Studio :: New Class File In App_Code In Vs 2010 In New Web Project Not Compiling

May 23, 2010

Best way to describe my issue with vs 2010.create a new website. create the App_Code folder. create a new class in the folder. put the line "x" in the class declaration. hit compile. And the website will compile with no errors. It's not "seeing" this new class as being part of the project best I can tell.

Setting Up A Project's Development Environment From Scratch?

Aug 27, 2010

I'm in the process of setting up a project's development environment from scratch. My company has used various technologies, but this is the first time we're able to focus on the development environment for a .NET project from the ground up -- and I'm the lucky guy who gets to make it work.

I'm actually very excited to do this, as it has the potential to become a pattern for repeated success across multiple projects.

I'd like your help to assess the build process that I'm using and shout out where I may find myself running into issues.

So, here goes--

Server Side:Windows Server 2008
SQL Server 2008 (relatively small / low traffic DB, wasn't worth devoting a separate VM in dev)
VisualSVN for hosting source code (just easier to manage on Windows),
Trac hooked into VisualSVN for wiki/bugs/tracking
NAnt for automatic builds / running unit tests
FxCop (potentially) as another set of tests from CruiseControl to check framework best practices
CruiseControl.NET for continuous integration, to automatically call the NAnt build and run NUnit / FxCop tests when new source is committed.
Dev Machines / Tools:VS 2010
NUnit
CSLA (potentially) to use in developing our business logic layer
NHibernate or Entity Framework (potentially) help facilitate OR/M

Visual Studio :: Running Project With VS Development Server?

Feb 25, 2011

I'm attempting to run/debug an ASP.NET MVC project under .NET 4.0 using VS2010's Dev Web Server. The server appears to spawn successfully and an instance of IE Explorer opens. However, the browser never seems to find the page. The browser just "spins" showing only a white page...no error message.VS is configured to randomly select a port, although I get the same results when configuring numerous static ports.The ASP.NET project is the start-up project.

How To Approach A Sharepoint 2010 Development Project Coming From WebForms And MVC

Jan 20, 2011

I have a good amount of knowledge in the ASP.NET Webforms and MVC worlds. Shortly I will be tasked with implementing custom web applications with Sharepoint. I have great flexibility with this project (i.e - I can use custom web apps outside of Sharepoint if that's possible) but like most projects the most limiting factor I have to deal with is time.

Here are some questions that come to mind:

Can I easily integrate a custom MVC project into Sharepoint 2010? What are the pros and cons if I can? Same as #1 only with Webforms. If #1 and #2 are not viable solutions, can I easily create custom web applications within the Sharepoint world? What will the learning curve be with my background? I understand developers can now use Windows 7 to deliver Sharepoint 2010 solutions. It looks like I can use a trial of Microsoft Sharepoint Foundations 2010. If that's correct, are there any development differences or gotchas I need to be aware of before digging into the Foundation version? I don't want to get up to speed on Foundation and then find out that the Server edition (the version that will be deployed) is vastly different.

How To Request The Extended Permission At The Time Of Authentication Only In Facebook App Development

Nov 8, 2010

I am developing a facebook application in asp.net using the facebook developkit downloaded from [URL] website.

I am practicing a sample application in SDK 3.02samplesIFrame.

They have give an attribute called RequiredAttribute = true in IFrameMaster.Master.cs, which will access the basic information.

But I want to request for extended permission in the same screen itself.

For that i have used this.RequiredPermissions = new List() { Facebook.Schema.Enums.ExtendedPermissions.publish_stream, Facebook.Schema.Enums.ExtendedPermissions.offline_access };

But there is no use.

Is there any way to do it.

Web Forms :: Page Aspx Download Itself (on FF3) Running At Server But Not At Development Time

Apr 19, 2010

I have a webform that has a master page. In the web form I have a dropDownList it has PostBack=True, cause every time I changed the option I concat paratemer (item choosen) at hyperlink's navigate url property, for example I have 2 items:

id text
1 Option1
2 Option2

If the users select Option1 then concat at the url "?option=1" The problem is, that when I choose one option and then click at hyperlink everything goes right, but at the second time I choose an option the browser try to download de page itself aspx. update: even if I click at other hyperlink or link button after choose an option and click the hyperlink, the same thing happens (the browser ask me for download the page aspx)

I have no idea how to avoid this behavior at browser and it happens just at server with the IIS not while I'm testing at VS2008, update: ah I almost forget, if I click "cancel" at the prompt of firefox, then everything goes right again, until the next time I choose other option and click at the hyperlink, then everything goes wrong again...

Update (Code):

[Code]....

And here is the ASPX page

Visual Studio :: Cannot Connect To Development Server After Closing The Server And Restarting The Project

Sep 29, 2010

I'm getting "Cannot connect to ASP.NET development server" almost every time I stop the ASP.NET server before restarting the project in debug mode. It can take between 15 seconds and 2 minutes to get the error message, and Visual Studio is frozen.

Sometimes I get three in a row, and I have to wait 2 minutes each time, or go into Task Manager and kill to process. Then I have to start Visual Studio 2010 again, which is at least three times slower than Visual Studio 2008 to open.

It's *extremely* annoying. I know I don't have to close the server if the code has changed, but sometimes I simply want to restart my website in debug mode (there is a cache on most web service calls, so this clears the cache). A workaround is to add "foo" code to a class and restart the project.

I'm running Visual Studio 2010 Professional on Windows Server 2008. I'm running the Visual Studio Power Tools too, with the latest update.

Configuration :: How To Modify Project Settings At Run Time

Aug 24, 2010

I have several settings in my project area (stored in web.config). However, the scope is not editable and is permanently set to "Application", which means I can't edit them at run time. I would really like to be able to edit these from the web interface. I know that doing so would restart the application (since the web.config was modified), but I'm okay with that, once the settings are written.

Is there any way to programmatically modify the settings in the <applicationSettings><PROJECT.Properties.Settings> area of the web.config?

Is That Really The Possible Thing To Happen When Hiding A Datafield

Aug 23, 2010

My code below has a drawback. The scenario is this, i have two user roles - Approvers and Encoders. The encoders are not allowed to view the price only the approvers. Using the code below, i can now hide the Price column. but the problem is, when the encoder modified the quantity column, the Total Amount (Quantity * Price ) is zero. Giving zero value for price. When the approvers view the transaction,the Total Amount is zero. Is that really the possible thing to happen when hiding a datafield?

HTML Code:

For Each colField As DataControlField In colFields
If TypeOf colField Is BoundField Then
Dim bField As BoundField
bField = CType(colField, BoundField)
If bField.DataField = "ReceivPrice" Then
bField.Visible = False ' Hide Price Column
End If
End If
Next

Is It Wise To Mix MVC Development And Web Form Development In The Same Group Of Products?

Oct 20, 2010

We have a largely asp.net web form team (With some Oracle developers thrown in).

Question 1:

Is it a good idea to start using asp.net MVC which will mean redevelopment of a number of standard controls for not much benefit.

Question 2:

Is it a good idea to hire developers where there most recent skills are with asp.net MVC?

I doubt there is any benefit adopting MVC now, given the 100+ applications in this suite of products, and the maintenance/rework this will cause. Given this, is there any particular reason to hire MVC developers, as they won't be hitting the ground running, which is what I need now.

Handling Exceptions That Happen In A MVC Controller Constructor?

Apr 22, 2010

What's the best way to handle exceptions that happen from within a controller's constructor?

All I can think of to do is use Application_OnError() or put a try/catch in my ControllerFactory.

Neither of these solutions seem ideal. Application_OnError is to broad - I have some non-mvc content in the site that has its own error handling. Using a try/catch block seems kinda hacky.

If I'm serving different content type -html/text/json/rss.... I would like to be able to handle the exception from within the action method instead of having to write all kinds of conditions to determine what kind of error message to serve.

What will happen to asp.net membership if the client browser blocks cookies? Does framework throw an exception when a user tries to log in or do something else?

Button1.Disable=false Doesn't Happen Immediately?

Dec 13, 2010

I have a Wizard which has a FileUpload in one of the steps. It also has an "Upload" button. When the user browses to a file, and clicks Upload, I upload the file into SQL.

There seems to be some synchronization problem for very large files, and I would like to disable the Wizard's Next button until the Upload of the file to SQL completes. It can take a while, especially on a wireless PC.

In my OnClick event for the Upload button, I am trying to disable the Next button. The code, which is below, appears to be correct, but the Next button doesn't actually disable until the Query completes. Can I get the Next button to disable immediately instead of after the SQL Update completes?

Here is my code:

Protected Sub JustificationDocUploadButton_Click(ByVal sender As Object, ByVal e As EventArgs) Handles JustificationDocUploadButton.Click
If RequestJustificationAttachment_FileUpload.HasFile Then
Dim obj As Object = Wizard1.FindControl("StepNavigationTemplateContainerID")
Dim startButton As Button = obj.FindControl("StepNextButton")
startButton.Enabled = False
SqlDataSourceJustificationAttachment.Update()
End If
End Sub
