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 am trying to redirect command line output to a list box in a vba macro, and I've found some code that I think might point me in the right direction, but I keep on getting the same error. When I use this code [code]It gives me the error in the title and highlights the first declaration line.What does it take to define a new "process".
Quote:Handles clause requires a WithEvents variable defined in the containing type or one of its base types.
That error is on both of these, in blue

i am trying to read an existing excel 2007 file from vb.net i used a form with single button and i written code in button click event code is :[code...]
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]

Actually this is vb6 to .net converted code. I m getting compile error at following line
temp = Lset(DispElem(i)) bcz Lset is not supported in .Net Lset accept string data type for first parameter and interger for second.If you know any alternet solution or if you have any source code for Explicit convert UDT to string type and vice versa.
Public Pixels(0 To 95, 0 To 127) As Variant Red = Pixels(X, Y) And &HFF i get this code from VB6, and when i transfer to VB05 i got problem said " Operator 'And' is not defined for type 'Color' and type 'Integer'. " i sent to VS2005
Public Pixels(0 To 95, 0 To 127) As Object Dim red As Object Red = Pixels(X, Y) And &HFF
In my application when i click the button i'm getting this" Operator '=' is not defined for type 'Char' and type 'Boolean'." But when i test it locally there is no problem at all!
In trying to add a bit of usage variety to a generic class I'm working on, I ran into this issue with trying to cast an object into an interface instance where the interface is defined inside the generic class.
i want to know how to type cast to user defined type in vb.net.I have a mark object which contains student id , subject name,subject id and mark. I have to read the subject id from a combo box and read corresponding mark value from it to a text box.
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?
CultureInfo As Any (this is where it said: Type 'Any' is not defined) Dim string1 As String = "strWordGuessed" Dim string2 As String = "StrWordToGuess"
when a user inputs a value into a text box, i am searching that value in my dataset.although the number that i entered is in my dataset, i am getting this excemption.
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.
