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.

I am an experienced developer but new to VB and I'm having a problem with viewing a subclassed tabpage in designer view. I have created several classes that are subclasses of TabPage. They display fine when the application is run and I can view the code with no problem.
However, when I want to fine-tune the controls and I go to the View Designer, I get a list of the controls rather than the displayed form. It looks something like this:
<icon>ListBox1 <icon>ListBox2 <icon>BtnAdd <icon> BtnRemove <icon> GroupBox1
I expect I'm leaving something out of my class definition which is as follows:
Imports System.Windows.Forms
Public Class TabPageExample
Inherits System.Windows.Forms.TabPage
Private sTestType As String
Private dTestDate As Date

View 4 RepliesThe 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 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.
Each time I drag the tables from the data sources into the form, frm, I get errors from the frm.designer.vb like

Please can someone point me in the right direction? I would like to build my own code designer window similar to that of the one within the VB2010 IDE.I am not sure how to tackle this, at first I was thinking of using RichTextBox as this can accommodate the fonts and colors.
An example of what I am trying to achieve.Should be able to outline, expand and colapse based on my own tags. e.g. in the VB.Net IDE a function and end function are tags that would produce an outline
Should be able to change color of text based on characters. e.g. ' would turn green in the VB.Net ide as it is a comment Should be able to indent based on specific tags. e.g. With - End with would auto indent within the VB.Net ide
I should be able to cover the text color and indents using RichTextBox, but I am struggling with the outline expand and colapse.The purpose of the project is to build a simple interface for creating config files that use only specific tags
I am devloping a custom designer (like the form designer), which can be used to design custom controls at designtime (see spoiler for screenshot).The problem is that i want to show the propertyes of the currently selected object in the propertygrid window in VS, and i can not figure out how to do that.

View 6 RepliesI'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:

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

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:

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).
