Compiler Error Message: BC30002: Type 'SharedBaseClass' Is Not Defined
Dec 7, 2011
I am running a web server using VB.net and I have a bunch of pages that need to utilize similar functionality, so I was thinking of creating a shared base class that incorporates all of this shared functionality. I created a file call it SharedBaseClass.vb, and I also have a class that should inherit from this class, SubClass.aspx.vb. The Top few lines of the the parent class look like this:
Partial Class SharedBaseClass
Inherits System.Web.UI.Page
And of the child class that should inherit:
Partial Class SubClass
Inherits SharedBaseClass
Then at the top of the SubClass.aspx file it looks like this:
<%@ Page Title="" Language="VB" MasterPageFile="~/Main_SA.master" AutoEventWireup="false" Src="SubClass.aspx.vb" Inherits="SubClass" %>
Assume that all of these files are located in the same directory.But when I try to run this, I get an error:Compiler Error Message: BC30002: Type 'SharedBaseClass' is not defined.And then the highlighted error is on the line that reads: Inherits SharedBaseClass I've also tried importing the file to no avail.

I've got an ASP.NET application that I installed by creating a web setup. I ran into a problem where ASP.NET wasn't registered with IIS so it gave me a "installation was interrupted" message that told me exactly nothing. Anyhow, I finally got it installed, and I can access the main page, but it's telling me that my class isn't defined. The dll is in the same directory as the Default.aspx page Here's the main error information
Compiler Error Message: BC30002: Type 'SIValidator.SIValidator' is not defined.
Source Error:
Line 4:
Line 5: <script runat="server">
Line 6: Dim validator As New SIValidator.SIValidator()
Line 7: Protected table As New arrayList()
[code]....
Is there some obscure setting that may not be set?

It is possible to create an instance of a C# class within a aspx.vb codebehind file?
When I try this within the Page_Load event:
Dim oFlow As New Flow(HttpContext.Current.Request)
I get the Type 'Flow' is not defined. The Flow class itself is located here:
App_Code/CSCode/Cust/Frm/Flow.cs
There's no namespace associated with this class.

I have a class named "Person" defined in the App_Code folder with Visual Web Developer 2008 Express Edition. It was working fine when I set it up the other day. Now, I get the message "BC30002: Type 'Person' is not defined" when I reference the class in my code behind page.

I'm getting a: mypage.aspx.vb(390,0): error BC30002:Type 'MyNamespace.MyClass' is not defined when I try to compile, run, etc. my website. What's really odd is that I don't have anything in my Error List before or after I do this. I wouldn't have an idea of what was wrong, except I have my compile verbosity turned way up. The line it's failing on looks like:

What can I replace this line with? I have read on the internet that since my application should be web-based, I cannot use the Windows namespace. I think what I am asking for is a pretty simple solution, but I am a very new VB programmer. More of my code below.

I am working on my new server now. I have created very simple page which has a for loop on code behind. If i dont define "i" as integer before the loop, i got this error
Compiler Error Message: BC30451: Name 'i' is not declared.
But, i can use for loops without declaration of "i" before loop.
For i = 1 To 10
Response.Write(DateTime.Now.ToString)

This error first appear to occur randomly. Steps to recreate:Open Visual Studio and load a solution (some files automatically opened) - this is when the problem occurs Close all open files Restart visual studio and load solution (no issues)Open Exactly the same files again, restart visual studio and load solution so files open automatically (problem occurs!)
However, when trying to narrow it down to a single file (that is automatically opened when the solution is loaded), I couldn't reproduce the problem. Now with all the files open again the problem doesn't occur!!! So it looks like it is fixed - though this happened before and eventually the issue came back.
I think it is to do with one of the user controls with DevExpress controls on it - when the error occurs, the designer displays the error. Though I can't reproduce it at the moment to confirm that.

I have this code working. It sets the Visible property of controlToSecure to False. [Code] However I would like to get rid of hardcoding types of properties. In this case i'm hardcoding Boolean. Instead I would like to define the property type dynamically. I tried it like below but I get an error on line 2 "Type property Type is not defined". I just defined that type on the line before though? Does anyone know why this doesn't work and how i could get it to work? [Code]

I'm trying to implement the GetHttpContext function from HtmlHelperTest.cs in VB.NET using Rhino Mocks, but I'm getting "Type 'HttpContextBase' is not defined." The compiler suggests changing it to HttpContext, but when I do that I get a run time error that a sealed class cannot be mocked.My test project references System.Web and also imports that namespace. Is there something else I need to do in order to get the HttpContextBase type to be visible to the code I'm witting?
Imports NUnit.Framework
Imports Rhino.Mocks
Imports System.Web.Routing

[url] aspx has an example of using invoke to write to a textbox from a different thread than where it was created. I need to do this in a current program I am working on, so I tried the VB version of the code in my VB 2008. I get an error at "Dim d as New SetTExtCallback(AddressOf SetText)" stating that Type'SetTextCallback' is not defined. In the example, SetTextCallback is not defined anywhere - something they left out?

I call the sub with:

The problem I have is that I get the error: "Type 'caller' is not defined."If I change GetType(caller) to GetType(vbLogin) it works fine. (vbLogin is one of the forms)I need to find a way to get it working using caller though.

I tried importing the System.Drawing namespace to this class which didn't change anything either. I've never really touched the OOP side of VB.NET before, this is my first attempt creating a class.
