View 8 RepliesI'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?
I am relatively new to asp.net environment.Recently working on a project, i discovered a problemi.e. I had to add using system.io to all file functions in any page. same for using sql functionsi.e. any method for that namespace had to be used in full like By adding the following section in web.config , ALL my pages automatically have access to that namespace
<namespaces>
<add namespace="System.Data"/>
<add namespace="System.Data.SqlClient"/>
<add namespace= "MySql.Data.MySqlClient"/>
<add namespace="System.IO"/>
</namespaces>

namespace Site {

public MyClass() {

The type or namespace name 'MyClass' could not be found (are you missing a using directive or an assembly reference?)
How to pass parameter while calling a class file in aspx.cs...my class file,
public ExifMetaInfo(Uri imageUri)
{
BitmapFrame bFrame = BitmapFrame.Create(imageUri, BitmapCreateOptions.DelayCreation, BitmapCacheOption.None);
_metaInfo = (BitmapMetadata)bFrame.Metadata;
}
I am calling this in my aspx.cx as,
protected void Page_Load(object sender, EventArgs e)

}
here showing error in (Uri imageuri);
I was just wondering, let's say I created a Method that is in a partial class in App_Code, and this Method would replace the same type of Method that would otherwise be in many files, and so, since it would be called from many files and would probably be called and used very frequently especially because of this. Would this overload this class? I'm not saying what would most likely happen, I'm just asking if it would be even remotely possible?
View 2 RepliesI have created a simple ASP.NET Website in Visual Studio 2008. I have a static C# class (lets call it someClass) contained in a separate file in the App_Code folder. I call a method from that class in my page's code behind like so:
someVar = someClass.someMethod(someParam);
This compiles correctly in VS 2008 but when I move it over to my IIS server, I get the following error (CS0103): Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. Compiler Error Message: CS0103: The name 'someClass' does not exist in the current context I have created a virtual directory for this website enabling 'Read', 'Run scripts (such ASP)', and 'Execute (such as ISAPI applications or CGI)'. I am not currently utilizing namespaces (as I thought I would not need to and I'm not sure how to use them properly). What am I doing wrong?
Is there a way to call a public function from a class?

I use vs2008 and my MVC 1.0 and 2.0 Projects were working perfectly but all of a sudden i have an error on trying to compile all of them;
The error is of the form;
Error 1 The type or namespace name 'Controllers' does not exist in the namespace 'XXX' (are you missing an assembly reference?)
Error 3 The type or namespace name 'Models' does not exist in the namespace 'XXX' (are you missing an assembly reference?)
Error 4 The type or namespace name 'AccountController' could not be found (are you missing a using directive or an assembly reference?)
Error 5 The type or namespace name 'IFormsAuthenticationService' could not be found (are you missing a using directive or an assembly reference?)
Error 6 The type or namespace name 'IMembershipService' could not be found (are you missing a using directive or an assembly reference?)
These errors seem to come from the HomeControllerTest and the AccountControllerTest.
note that i recently installed Azure Tools using the Web Installer..Dunno if that could be the cause or problem.
when I put a break point i get this error message:
Error 1 The type or namespace name 'X509Certificate' could not be found (are you missing a using directive or an assembly reference?) D:UsersatttDesktop

I' m simply trying to import code from one namespace I've created into another .net application. I add the reference into my other application, but when I do a build, I get the following error.
Could not find file 'Microsoft.Windows.CommonLanguageRuntime, Version=2.0.50727.0'
This only happens on a particular namespace I've created, all others work fine.

I would note that I updated to VWD Express 2010 then had to revert back to 3.5 because my host at Arvixe had not updated my server yet. He then said he updated it and I reverted up to 4.0 again. It turned out he hadn't and I tried to revert back...and then this showed up and numerous other errors.
I've just setup a new site on my IIS6 and I'm experiencing the following problem:
I can run normal HTML pages, but no .aspx files. If I call the aspx page directly I get a 404 - file not found - error message. This only happens with .aspx files.
tell me the class hierarchy of System.IO namespace?It's not clear in MSDN library.

When 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).

View 5 RepliesCurrently, I have many controls and objects such as Chart1 of mschart as part of the public partial class _Default : System.Web.UI.Page.
At the bottom, I've created a second class that is not part of the _Default webform class. How can I access the webform controls from this second class?
For example, I want to do
Chart1.Series["Series1"].Points.AddXY((pointIndex + 1) * 40, datapoints[pointIndex]);
I want to pass pointIndex integer and the datapoints array.
I know that Chart1 was created protected global access modifier in the designer.cs but when I changed it to public, it still had a problem.

I've inherited a half completed application that seems to use a model that I'm not sure can reliably work.It is a ASP.NET webservice that on each call loads a unmanaged C++ .DLL using
[DllImport ( "kernel32.dll" , EntryPoint = "LoadLibraryA" )]
public static extern int LoadLibrary( string lpLibFileName );.
[DllImport(@"MyUnamanagedDLL.dll")]
public static extern string DoStuff( );
In the unmanaged C++ .dll it is using a singleton to hold state between calls.This is so that it only has to initialise once and load a bunch of slow stuff from disk and database rather than on each webservice call as this is too slow.
I have the following method in a class withing a website.
public static void Authorise(int role, Page callingPage)
{
callingPage.Master.FindControl("divUnauthorised").Visible = true;
callingPage.Master.FindControl("ContentPlaceHolder2").Visible = false;
}
Now this works fine but I really want to just have the one parameter of role and not require the page to pass itself into the method. Is there a way of finding the object that called the method and casting it to a System.Web.UI.Page?
