Type Not Defined Error When Creating Class
Feb 26, 2012
First I put it inside a Module and it works just fine. However when I created a Class and put it inside it, it showed up some errors. (they are in the code's comments)
Public Class MyImageClass
'function to merge 2 images into one
Public Function Merge(ByVal img1 As Image, ByVal img2 As Image) As Image 'Type 'Image' is not defined
Dim bmp As New Bitmap(Math.Max(img1.Width, img2.Width), img1.Height + img2.Height) 'Type 'Bitmap' is not defined
[Code] .....
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.

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 have been having some trouble today with a User-Control of mine. Is what is happening is when I try to build an application with the control in it, the Form.Designer has an Error saying that Namespace.ControlClass is not defined. I have no idea what the problem might be and hope that one of you do.The weird thing is that the Control Builds just fine and I can drag it from toolbox to the form and THAT works. Also, it works just fine in Design-time. It didn't start erroring until either, I upgraded it to VS2010 or until I changed it a bit today. If necessary, I can post it here.

I am in the process of migrating from VB6 to VB 2008. In a pixel grid system I have thousands of cells with about 15 properties each. In VB6 I employed the user-defined datatype "udtCell()" as my array structure. Is this still a good approach - or should I perhaps make Cell a class?

I'm running a button click event so that it will open a spread sheet from a certain path and export it as a pipe delimited as a seperate file name. Everything looks fine except for this one error I keep getting..."Type 'Excel.ApplicationClass' is not defined". I have imported Microsoft.Office.Interop.Excel as well and have added a reference library. I am currently running Visual Studio 2010. Here is the code.
Private Sub btnRun_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

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'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 have the following
Sub ChangeLanguage(ByVal caller As Object, ByVal lang As String)
Dim c As Control = caller.GetNextControl(caller, True)
Do Until c Is Nothing
[code].....
I call the sub with:
ChangeLanguage(Me, "en")
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 am writing some simple utility applications in VB.NET. I am using Visual Studio 2010 Express.I'm trying to throw a FileFormatException exception in my code if a user specifies a file that has the wrong extension. Documentation indicates that this exception has been around since .NET 3.0. See
[URL]
However, Visual Studio gives me an error saying that System.IO.FileFormatException is not defined. It's not a typo, either. FileFormatException appears in the object browser in System.IO, but doesn't appear in the Intellisense drop down when I type System.IO.File.
Here is my simple function:
Function ValidateDBFile(ByVal DbFilePath As String) As Boolean
ValidateDBFile = False
If IO.File.Exists(DbFilePath) Then
Dim flInfo As New IO.FileInfo(DbFilePath)

I dont get this. I use code from one project that works and paste into anther and now its full of errors.
I have no clue how to solve this (See attached image).All of the errors have to do with Excel and Outlook applications.The info for "Imports" section is the same as my other project and all the "Dims" are the same as well. (These are two separate projects).Basically, I copied a form from one app and made a stand alone app for that form.

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.
