Error - It Complains In The "Designer" That "Type 'namespace.dataset' Is Not Defined"?
Apr 29, 2010
In a VB.NET Windows form, I have a form named "form" I got this error in the form.Designer.vb whenever I assignt a data bound to a control. It complains in the "Designer" that "Type 'namespace.dataset' is not defined". The dataset is attached to the form in the design mode when I assign a data bound to a control to the Windows form and it generated the code to the "Designer" page. I can go to the "Designer" page to remove the "namespace" of the dataset and the error disappear. However the namespave re-appear to the dataset in the "Designer" page once I open the Windows form in the design mode.
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've create a new VS 2008 Window Form Project using VB. I added an oleDbDataAdapter to the first and only form, set it to a table in my Access 2007 Database (there is only one table, PK field autonum of course and two Memo fields). The Database is in the Project's folder. A standard oleDb Connection object was created, as I expected, then I select the DataAdapter and choose 'Generate Dataset' which produces a standard DataSet called 'DataSet1.xsd'. Now when I build the project I get an error 'Error 1 Type 'FontTest.DataSet1' is not defined.' I do have a reference in my new Project to System.Data.So what the @#%$@ is going on? Why isn't the Dataset create by the DataAdapter being recongized? I can get into the DataSet Designer. The DataTable create is perfect, three columns defined correctly as I expected.
CREATE TABLE [LogLevel] ( [Id] int primary key ,[Name] nvarchar(50) not null
[code]....
After creating a fresh endity model, I add the two tables above. When I try to build I get the following errors...
Type argument 'Inxsol.CommandPlan.Data.Model.Log.LogLevel' does not satisfy the 'Class' constraint for type parameter 'TEntity'. Value of type 'System.Data.Objects.DataClasses.EntityReference(Of Inxsol.CommandPlan.Data.Model.LogLevel)' cannot be converted to 'System.Data.Objects.DataClasses.EntityReference(Of Inxsol.CommandPlan.Data.Model.Log.LogLevel)'.
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 'My.Computer.FileSystem.CopyFile(txtBrowse.Text, "Original_Copy.xls", Microsoft.VisualBasic.FileIO.UIOption.OnlyErrorDialogs, FileIO.UICancelOption.DoNothing)
I am using VS.Net 2003. I have a solution that contains 4 projects. The first project contains the definitions of interfaces. The third project is using the interfaces defined in the first project. For the third project, I added a reference to the first project. But I'm still getting a build error
I am attempting to update an existing winforms application, that was created with a dataset control on all the winforms pages. I have ported it from VS 2008 to VS 2010 and I need to update the database section and connect it to the SQL backend using traditional code method.In the Solution explorer, when I click on the Dataset files, and click "Exclude From project" I am unable to build the project.Is it advisable to comment out the code lines that refer to the dataset in the .designer.vb files?
Type 'datestamp' is not defined...How can I update it to resolve the error..

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?
[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?
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 found the code below and when i run it I get the message Type 'BindingSource' is not defined. What do I need to do to get it to work. I just want to run it and try it out!!!!!!
I am experimenting with RavenDB embedded in my application. I am receiving a "Type 'EmbeddableDocumentStore' is not defined" error. I do, however, have a reference to Raven.Client.Embedded in my project.
Here's my VB.Net code:
Imports Raven.Client.Client Imports Raven.Client Sub Main()
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.
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 get this error on this line: System.Runtime.InteropServices.Marshal.Copy _
(Scan0, Data2, 0, Data2.Length)
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
I also sometimes get an error on this line:
Dim dc1 As IntPtr = CreateDC("DISPLAY", Nothing, Nothing, CType(Nothing, IntPtr))
What I'm trying to do is take a screenshot and then read the colors of pixels. I currently have a working vb.net copyfromscreen method but it's SLOW and using 100% cpu usage.
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'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:
