Identifying A Correction For An Error In The Application.Designer.vb Screen?
Feb 15, 2011
I've been trying to complete a program that I have to write for a class but keep getting an error that when double clicked, takes me to the Application.Designer.vb screen. The error that shows up in the Error List is "Employee' is a type in 'WindowsApplication1' and cannot be used as an expression." The resources I've tried to use (book and web) have been no help. Does anyone know what needs to be done to correct this error so I can test my program and correct any other possible errors? I can also provide the code for the program, if that will be any help. Here is the code that shows up in the Designer window:
I am using the following code in the 'Application.Designer.vb' to set one of the two forms as the the mainform for my splash screen.The global string array gSetupStr(0,1) only produces a correct result when any Msgbox is inserted before the 'If' statement.However,I do not want the Msgbox during a splash screen, but do want to control the mainform.

When i try to view MDIParent screen in designer mode I'm getting below exception...
`Could not find endpoint element with name 'NetTcpBinding_IMyService' and contract 'ClientProxy.IMyService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element.'
Little background to understand my question more clearly...
I've a WCF server which I'm trying to consume in my Winform application. So i've created a separate class library in which i added service reference and created a proxy. I've copied the client endpoint info from app.config in class library to UI app.config file.
When i run the application everything is working fine but when i try to open MDIParent screen in designer mode its throwing above exception.
Note: I think i'm getting error because i'm trying to create a proxy object on NEW method (form constractor) if i comment that line - i'm able to view designer screen.
I am working on a application which is basically a screen designer. I have implemented the form designing capabilities using IDesignerHost and other interfaces. In my application user can pick a component from toolbox and drop it on the designer screen and can configure the properties from property window. I have my own set of properties which gets populated from database. Screen designer is working fine but the problem occurs when user changes some properties from property window. Say user changes property 'Width' then I change the width of the selected control in designer but the problem is SelectionOverlay shows the old size. When I select another control and select old control again, SelectionOverlay(resize handlers which appears around the control) shows properly. How can I tell the SelectionOverlay that the size of the control is changed.
I am using 2010 express, and when I try to use it to open a program that I had made with 2008, it will open and it will allow me to debug the program, but neither the designer nor the code will show. It is just an empty space in the middle of the screen.
I have a few textboxes for inputing values in, but i want a textbox to prompt me if I have made a mistake inputting values, as well as setting focus on that textbox with the mistake, how do I go about doing that? So far, I have[code]...
The Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.
im about to develop a small appliacation for a bet system, which needs 6 screens, each screen will be a touch screen for each client... the application will be running in one computer only just with 6 screens. my question is does anyone knows how to control each screen separately?. somethign that would allow me to output each forms in different screens would work fine.
I am making a program that will put a black mask over an application (like a full screened game). This black mask will fade in and out, depending on certain criteria. Is there a way I can do that with VB? It's to help me dim my monitor without having to push anything.
Private Sub RichTextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged RichTextBox1.SelectionLength = 0 Dim words As New List(Of String) words.Add("Test")

I've started a project in Expression Blend and has been working the codes in Visual Studio 2008. It was alright, no problem. I've worked heaps of projects like that before without any problems. However, out of nowhere, my WPF designer in VS2008 now gives me the following error:
Object reference not set to an instance of an object. at MS.Internal.Package.VSIsolationProviderService.CreateIsolationProvider(String identity, AssemblyReferenceProvider assemblyReferences, IEnumerable'1 assemblyFolders) at MS.Internal.Providers.VSDesignerContext.GetIsolationProvider(IServiceProvider provider, [Code] .....
It displays the above instead of displaying the WPF designer. Also, I cannot Debug>Start Debugging the application anymore. I can still run/test/build it in Expression studio though. The funny thing is that if I restart a project in Expression blend, copy all the xaml codes, and copy all the vb .net codes from the original application, it works for some time, and then afterwards start giving me the same error at wpf designer in VS2008.
I just made a bunch of changes to my program, so I can't just undo what I did. My main form gives me the following error every time I try to load the designer:
Warning1Value cannot be null. Parameter name: objectType
I have rebuild the project with no success. A few other posts have mentioned that there could possibly be a reference to a button or image that no longer exists, but I have no idea which one.
Also, I don't really know what the information below means, but it shows up on the error page under 'call stack', so I figured I would include it
at System.ComponentModel.TypeDescriptor.TypeDescriptionNode.GetRuntimeType(Type objectType) at System.ComponentModel.TypeDescriptionProvider.GetRuntimeType(Type reflectionType)
I don't know what I may have clicked on but, in Solution Explorer under My Project, there are now duplicates of Application.Designer.vb under Application.myapp. One is named Application.Designer.vb and the other is named Application1.Designer.vb. If I comment out the code on one of them them build works without errors.
However, if I delete one of them, I get a warning "The custom tool Application.Designer.vb failed while processing the file 'My Project.Application.myapp." but it still builds. If I click on the warning, a messsage window appears with "The last attempt to run the custom tool 'My Project.Application.myapp' failed. Would you like to re-run the custom tool?" If I click NO, the program builds. If I click YES, it adds the duplicate Application1.Designer.vb again the the errors are back.how to eliminate the errors and the warning?
I was working on my project (creating a new form), and when I switched from the code view back to the designer view, I got the following error:
The designer cannot process the code at line 118: Me.VDARSQLDATASET = New Veterinary_Digital_Anesthesia_Records.VDARSQLDATASET() The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again.I am now getting this error on every page. This project has been working for months just fine, but for some reason the VDARSQLDATASET has dissapeared- kind of. I can still access the dataset (the file is still there), I just can't reference it in the code (intellisense can't find it).
I have opened a VB project which was created using a previous version of VB. So, it popped up the conversion wizard and it completed the conversion to 2010.
But when I tried to view the forms (using "View Designer"), it shows the following message[code]...
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?
I want to add a List(Of Book) property to my user control. I defined a Book class and BookCollectionEditor class for CollectionEditor. And also I defined a public property named BookList for my user control. For a custom control it works fine but for user control, the designer does not display my property. On markup I can add a Book item but on designer it gives error: "Type 'System.Web.UI.UserControl' does not have a public property named 'BookList'."Isn't is possible to define a list property for a user control?
<TypeConverter(GetType(ExpandableObjectConverter)), Serializable()> _ Public Class Book Private _name As String Private _author As String
I am working in Visual Studio with a solution containing multiple projects. The solution is based on a co-worker's computer. I am trying to build the project, I get the following error:
Error 17 Unable to open module file 'C:DocumentsVisual Studio 2010Projects ReportCreatorMy ProjectApplication.Designer.vb': The system cannot find the file specified. C:DocumentsVisual Studio 2010ProjectsBlahBlahBlahReportCreatorMy ProjectApplication.Designer.vb 1 1 ReportCreator
It is on my co-worker's computer, but I don't see it in source control. He has ReportCreator checked out. How do I create Application.Designer.vb?
I though I had solved this problem, but it is back:Code generation for property 'SelectedPeople' failed. Error was: 'Type 'ECS.Entities.Persistency.Person' in Assembly 'ECS, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.'The property on the error message is a List(Of Person) and for some reason it trigger this error, for almost anything I do, and its getting really anoying.Okanswering to the answers here is a little more information about the problem.
Yes it is during design time, it happens bascially anytime a open a form that has a UserControl that contains the Selected property in it, sometimes it happens even if I don't have focus on the form, also if I try to compile/run it happens and the message come in the form of a Message Box with just a OK, ECS.Entities.Persistency.Person is just a LINQ to SQL Generated Class, this should not matter at all to the problem, although I have added the attribute before the posting.he reason that this happens is because the Designer attempts to put the property on the Property Panel, and for that to happen, serialization happens.tryed to hide the property from the designer by using this attributes.
<DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _ <Browsable(False)> _ Public Property SelectedPeople() As List(Of Person)
I am trying to use a script mananger to use page methods to communicate between the server and client side of my page. I have added this code to the html
I have a project with multiple forms that are used to edit tables in a project data source (access DB). All the forms work fine, except the ones that use designer generated lookups.
When I am editing a row in a bound DGV on the lookup forms, they function fine, and the save button works fine. However, once I go to close the form it starts throwing "System.ArgumentException: DataGridViewComboBoxCell value is not valid." multiple times.
I've created applications similar to this in VS2008 without any issues.
[code]I have this XML file, how do i get the ID attribute? this question is not about "how to get attributes in xml's", i've found several solutions, but somehow i can't address to this specific attribute in this specific node.i can get info inside tables that are within "infNF" and i'm loading it into a dataset and using this code: ds.Tables(Table).Rows(row)(node)is there a similar way to do what i want to get THIS attribute?
