View 4 RepliesUse The System.Threading Namespace In Asp?
Mar 19, 2010This may seem like a really simple question, but can I use the System.Threading namespace in ASP.NET web forms? I have a web page which uses HTTP GET/POST to gather page customisations (title, subtitle, etc.) from the user and numerical input which is passed to a ASMX web service. Currently they work sequentially, the customisation first followed by numerical processing. So can I use threading to do this?
View 3 RepliesTrying To Import The System.Web.Profile Namespace?
Mar 18, 2010I am using vb.net/VS.Net 2008/3.5. I am trying to Import the System.Web.Profile namespace like so:
<code>
Imports System.Web.Profile
</code>
However when I add that in I get a green squiggly error line that when hovering over shows me "Namespace or type specified in 'System.Web.Profile' doesn't contain any public member or cannot be found. Make sure the namespace or type is defined and contains at least one public member. Make sure the imported element doesnt use any aliases" When I use intellisense I see only three namespaces for system.Web, which are:
<code>
Imports System.Web.AspNetHostingPermission
Imports System.Web.AspNetHostingPermissionAttribute
Imports System.Web.AspNetHostingPermissionLevel
</code>
Do I need to add a reference in order to see System.Web.Profile?

.net - System.Web.HttpException Could Not Load Type '[namespace]?
Feb 7, 2011This started as Could not load type 'Global' error. After I tried a few things and getting no where I deleted the Global.asax file and now the error is Could not load type '[namespace].???'Where ??? is the class name of every page I try to load.The web site (when executed within VS2008, local dev computer) works fine but once published (with no errors) and deployed to the server gives me Could not load type '[namespace].???' error
I did install elmah and I was able to get more details for this "generic" Could not load type '[namespace].???' error
elmah reports a HTTP error 500 :
System.Web.HttpException Could not load type '[namespace].???' ->
System.Web.HttpParseException: Could not load type '[namespace].???'
I have checked the "basics"
References
Doing a clean and a build Checking the Inherits attr in the HTML against the code behind
UPDATE #1 I did deploy the site to a different DEV computer (configured IIS, virtual folder, etc.) and it works. When I use the same published code on the server, get the generic Could not load type '[namespace].???' error
UPDATE #2 I created a test web app. One form (Default.aspx) with a button. The click event does a Response.Write("Hello World"); I moved this app to the server and guess what, I get the Could not load type TestSite._Default
UPDATE #3 According to the fusion log viewer, these two websites are attempting to load CppCodeProvider and VJSharpCodeProvider, but I have no references to any of these. After a Google search, I found this post.I checked and I have no references to JAVA files.

View 2 RepliesHow To Find The File Path From A Namespace.class Name
Aug 26, 2010I'm programatically looking ito a .aspx file and getting the file class name declared in its CodeBehind. For example, when analyzing myFile.aspx I read in its Page Directive and found its CodeBehind equals "myApplicationmyPage.aspx.vb". Then I use the code
below:

Now I want to read the BaseFile (class = myApplication.Forms.BasePage). However, to read in this file, I need I need to get its full path instead of its namespace.class hiearchy. In this case, the BasePage is wrapped in a different namespace declaration thus I cannot just change the '.' to '' in order to get the path.How can I get the path of BasePage so I can read it?

View 8 RepliesVisual Studio :: Unable To Access System.XML Namespace From Macro
Mar 10, 2010I am trying to write a macro that accesses an XML file external to the editor.
For some reason, I am getting error messages on everything within the System.XML namespace
'Type XmlDocument is not defined'
'Type XmlTextWriter is not defined'
'Type XmlElement is not defined'
( etc... etc... etc... )
I've imported the namespace at the top of the editing context within the macro IDE:
Imports System.XML
I have also tried to reference the namespace members with a complete namespace reference:
System.XML.XmlDocument
It didn't work. It is still being indicated as undefined.
I've tested the code from within a stand-alone console app, and it works fine.
From this, am I to conclude that the System.XML namespace is not accessible from the macro facility?
Is there another option?

(Because nothing also happens when I try to add a reference to System.Web which is definitely referenced!)
View 6 RepliesSpecify CLR Namespace Of Auto-generated Web Service Proxy Class?
Sep 10, 2010When you add a Web Reference in an ASP.NET project in Visual Studio the web application's root namespace is always added.So, if I add a web reference called MyWebService and the default namespace of the application is MyApplication the namespace of the generated proxy class will be: MyApplication.MyWebService.
However, I want to be able to specify which namespace to use for the generated class (to skip the default namespace and have the namespace be called simply MyWebService).Is using wsdl.exe through the command line the only way of accomplishing this? I don't want to manually edit the generated class (since it can get re-generated).
