Use The Variable Instead Of Value For A Property In Form Designer
Dec 14, 2010
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 am working in VB.NET 2010 Framework 2.0.
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.

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 have an abstract user control(baseModule) that has a property that I plan on using a bitwise comparison on to determine what export types are supported by that module. In the designer of a module derived from baseModule, I am presented with a combobox with the ability to just select a single value (Html, Xml, etc.) I would like to be presented with a drop-down checked listbox so I could select which values I want.How can I accomplish this inside of VS2008? I've seen other properties support this.
Public Class ExportTypes
Public Enum ExportType
Html = 1
Xml = 2[code]......

Ive recently written a control called a ButtonRow in VB.NET that allows you to dynamically place buttons on it through a typed collection property. The property itself is tagged with the <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)>. However it works really bad. First of all, whenever you add buttons to it and you delete the controlafterwards, the designer code file still have the buttons declared but without the aButtonRow to who's collection they would be added. Secondly, you cannot copy the controlfrom one form to another. It would just copy the ButtonRow object without the buttons

I have some related Properties in a class. Namely, One is a collection of objects and the other is an index to the one that the class instance is looking at. In the designer, I need for the collection to be set prior to the index. I tried to do this manually, but when the file is saved, the Designer goes back and writes over my change. So I need to know how to tell the designer in which order to set the properties.

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 have written a Visual Studio 2008 addin that adds controls to a Form. I want some of those controls' Visible property set to False so they're hidden during runtime, so I do this:[code..]
This doesn't work. Not only is the control invisible in the designer window itself, but the Visible = False code doesn't even make it into [FormName].designer.vb. I have tried forcing Serialization on the Visible property like so, to no avail:[code...]

I have been making a control and have added a property for a list(of CustomClass). The custom class contains a string, an image and a list of another custom class which contains a string and an image. I have added this property to the designer by adding the browsable attributes and all appears to work correctly with this.
My problem comes when running the program. I can set all of the values within the property and I can go back to them and they are saved, however, as soon as I run the program, the values are wiped out as the property is set to Nothing.In order to allow my property to be edited and saved, I realize that I must initialize the list and have done so in the accessor method of the property (if the property's value is nothing).
I have modified the values in the designer and placed a breakpoint on all of the items which use the property and it's underlying field, as well as on the property's methods itself. The first breakpoint hit is of it being accessed and the value is always nothing.
I'm not sure where the values are supposed to be stored as I have checked the designer code where it would normally store types such as strings and I have checked the resources to see if they have been saved there (like an image would be). After running the code, the values in the designer are wiped out also.

Now I have the need to get a current value from a bindingsource in a property of a user control.In a previous thread I had tracked down the "Object variable or With block variable not set" to the return in the Get block of a property. At the time I was only using the Set so I just commented out the offending code until I needed it.
[Code]...
The error does not occur during a system compile, only upon saving the container object of the user control. As I said the Set works correctly, only the Get causes the error.I would like to know what I am missing/misunderstanding and am open to other suggestions of handling retrieving the current value of a bindingsource in a user control.

I am using Linq to Sql that generated a data contract for a table. I have a date field in that table which is a non-nullable field. I need to override the auto generated property of the date field to return a specific value, something like [code]Is it possible to override an autogenerated property in the designer.vb file using a partial class? I dont want to create a new property as it is currently being accessed in n number of places and I dont want to change it in every place.

I'm creating a UserControl that draws a simple radial gauge. I need it to be very customizable; the user should be able to customize everything such as the colors, fonts, sizes. So, I just made a property for every customizable detail. For example, I had ScaleFont, ScaleColor, ScaleStart, ScaleEnd, ScaleInnerRadius, ScaleOuterRadius, ScaleTickmarkFrequenty, etc.. etc.. etc...
Because there are so many properties about the same subject, I wanted to 'group' these properties into one "property". I've seen this done loads of times in third party controls, but I've never done it before myself.The idea is that the properties can be accessed like
Me.Gauge1.ScaleSettings.Start = 10
Me.Gauge1.ScaleSettings.End = 80
...
So far, I tried creating a class for each group, for example a clsScaleSettings class, containing properties like Font, Color, Start, End, InnerRadius, OuterRadius, TickmarkFrequenty, etc (corresponding to the same properties as above).
Then, for every 'group' or class, I create a Property. For example, I have the ScaleSettings property, which simply returns an instance of the clsScaleSettings class (I initialize the instance only once of course):
vb.net
Private _ScaleSettings As New clsScaleSettings
Public Property ScaleSettings() As clsScaleSettings
[code]....
Now, this works in the code editor. I can now use
Gauge1.ScaleSettings.Font = Me.Font
for example, and it sets the font correctly.But, I does not work in the designer, in the Property Grid. The whole reason I made the effort to move and rename nearly all properties (about 70!), and all references to those properties, to separate classes, was so that the user could design the gauge more easily using the Property Grid!Instead of having 15 settings related to the scale, scattered all over the Property Grid, he can now have one ScaleSettings property, which he can expand, and then he can edit the properties of that group easily.The ScaleSettings property is greyed out in the property grid... So I cannot expand it and view it's underlying properties.

I'm writing a custom control and I want to add a "MessageText" property of type String:
<Browsable(True),
DefaultValue(""),
Category("CustomControls"),
[code]....
The MessageText property is a multiline text, and the user must be able to set the text using the designer. The problem is that the designer doesn't allow to enter a newline directly for a string property.I want the same behaviour as the system TextBox's Text property, where you can click on the down arrow and write lines in the small text-editor that appears:How do I do that?

Long story short I made a form in VB.Net project which involves lots of icons and images. My problem is when I build my project, and then go back to that form, suddenly errors showed up.
The errors says : "The type 'MyProject.MyResources.Resources' has no property named 'myicon'". Just to be clear, it worked fine before I did the build, and it happened to every single images I have on Resource.
When I chose "Ignore and Continue" all of the images I used are gone. I tried to googled it, some says to delete my .exe file on Application/Bin/Debug folder, which is working. But this issue has been some kind of an annoying one, since it happens again every single time I build.

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.

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..
