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.
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 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 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.
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?
My self and most everyone else on our team is having the same issue with VS2008. The designer will not render many forms in designer mode. Currently I am getting this error "The type 'Team.CAD.UI.My.Resources.Resources' has not property named 'view_16'" Well veiw_16 is in the resouces file.
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 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 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'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 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 was busy with a project, i'd thought I take a pauze of an hour I closed my computer. Now I open my project I have my wirtten codes but I can't see the designer anymore.. what can be the problem and how to get it back?
I use MS visual studio 2010. I did open designer and view the form for the same file A before. But after some small changes, I can no longer view the form designer.vb, but can only view code in designer.vb. Even if I go back to the original source, I still can not open designer!!
The error is: The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following clsses in the file A-The base class BaseClass could not be loaded. Ensure the assembly has been referenced and all that projects have been built.
if i click the designer tab i can only see a white form and the text say "Me.Database1DataSet.DataSetName = "Database1DataSet" and "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"?
During my project I have suddenly lost my form design, all the designer code is still there but when I try and view the design layout it gives me an error saying 'navigation to webpage has been cancelled', does anyone know how to get around this extremely annoying bug ??
Yesterday I installed vs2008, installed SP1 all seems well.I have converted a project (from VS2005), it works fine but....When I try and modify any of the forms none of the controls aer displayed on the form.Additionally I have noticed that each form has a formname.designer.vb file, the top few lines of the code in the designer.vb files are;
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _ Partial Class frmFullMarketView Inherits System.Windows.Forms.Form
[Code]....
Then my controls are listed. Do I have to copy the code held in the seperate designer.vb file back to the 'formname.vb' file for all my forms?If so, why does VS2008 create all this extra work when converting forms from vs2005?
Using the new Visual Basic 2005 Express Edition Beta.Created a project, form, controls, etc. Worked great. Love it, compiled perfectly.Saved everything, closed the program, went to bed. Woke up, opened the project, but now CAN NOT open the form (form1.vb) in Designer mode!! I can open the code, it's all there, exactly as I left it, but cannot get back to the designer mode to (easily) add more controls to it!F7 just opens the code, right-click just gives me code option, not designer option.This is amazingly frustrating..
I have a project in MS Visual Studio 2008 - VB.NET. I have opened and closed my project which consists of two forms multiple times.Today when I open my project I cannot find one of my forms in designer mode.If I run my application the form displays correctly but I cannot view in designer mode to make changes.
I am working in VB.Net 2010 framework 2.0. Suppose i declares a property
[Code]....
In the form designer, the property "MyColor" will be seen the value as 150, 145, 145. I want to see this value as "NewColor" in form designer. This is the same like ControlDark, ActiveBorder etc. system colors. I want that instead of the color value, designer should show the variable name. The .Net framework also use the above implementation for System Colors and same i want to do.
I copy/paste controls in the projects, then I noticed that there are many controls are listed in designer.vb which actually are not being used. how can I clean these? will it affect the UI performance? or, it does nto matter at all
I don't want to allow some properties from going into form's designer file but the those properties will present on the form(property grid). The behavior of these properties will be same always.
I used the following code:
<DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> Public Property GradientBegin() As Color = Color.Red
But the problem I am facing is that -> on the property grid after changing the "GradientBegin" color to other than RED and compiling the program, it is replacing the new changed value to RED again. So I am not able to change the color actually.
On a recent project I stumbled across a page of code that looked unfamiliar, but which evidently was the code behind my form design. I'll copy and paste an excerpt to show you what I mean:
'Required by the Windows Form Designer Private components As System.ComponentModel.IContainer 'NOTE: The following procedure is required by the Windows Form Designer
[code]....
I thought this was a useful way to back up my project via email because it's in text form. But now I can't find the same information. I've looked in the Object Browser but couldn't find it anywhere. I think I stumbled on it the first time by right clicking Go to definition, but now that doesn't take me anywhere if I click on say form1. So where will I find this mysterious page that has all the form items information in text, not graphic form? Can't find it anywhere.
i have recently tried to copy my project between two acciunts, one which i access the project on a network drive and one which i will run programs from on the C:/ drive... when i tried to copy the project between accounts i began to receive the error message shown below
Just wanted to know if you had some design code which was created, and that is all you have. Can you open this designer code and create the actual working main Form from this? I don't need this designer code for any specific task, just wanted to know if there is a command within VB Studio 2010 that creates the actual Form from the design code. For example; The following piece of designer code is for a simple program that finds the Circumference of a Circle.
