VS 2010 Type CLASS Not Defined?
May 29, 2010
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.

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 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 trying to import data excel (*.xlsx) to reportview... but i'm getting stuck for six hours to solve this problem :
type OledbConnection, OledbAdapter, and OledbCommand is not defined
i also couldn't find any reference named Microsoft Jet OledB 4.0 in my visual studio 2010 ......... but i find Microsoft Jet and Replication Object 2,6 Library... i added it to my reference , but it didn't work to solve my problem where can i download reference to Microsoft Jet OledB 4.0... is there any mistakes in my installation package visual studio 2010? once, i got message that type "crystalreport" is not defined, probably because i use visual studio 2010 that's not include crystal report in their package installer, and i decided have to download it as 3rd party..here my codes so far... i'm not finished it yet to the report view... i was stuck in this "type not defined error"here i attached also my files ( my macro.xla (zipped in *.zip), and some excel files to execute)

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.

It looks to me like a reference error yet all Crystal reference are included. I have set up a test program and this work fine. Yet when I run this in my main program I get this error. This is trying to run a Crystal Report. I know this is Crystal but I don't think it is an error or issue with Crystal I think it is more related to the the set up of the program.

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]

The following code at run time gives the error - Opearator '=' is not defined for type DBNull and type 'Boolean'.
The reason is the data at the table is set as NULL value.. How can I change it to accomodate the error.

I am trying to write a class to implement search as you type. e.g. a form has a textbox and a listbox. Each time the textbox text changes, the list is the list box is filtered accordingly. E.g entering "ha" in the textbox would cause the filtered listbox to display 'I plan on implemtneting a sayt class.(see example below)
The thing I am having problems is working out how the two controls will 'talk 'to each other.
e..g when the textchanged event fires for the textbox, how does a sayt object 'know' that it needs to refilter the listbox?

To correct this error I use the given help that microsoft provides below and i am still getting the error messages can anyone assist me with the source codes if i send some code snippets?Check that the type definition and its reference both use the same spelling.
Check that the type definition is accessible to the reference. For example, if the type is in another module and has been declared Private, move the type definition to the referencing module or declare it Public.If the type is defined, but the object library or type library in which it is defined is not registered in Visual Basic, click Add Reference on the Project menu, and then select the appropriate object library or type library.
