A component I'm making has a public property that represents a percentage. How I can give it a % symbol in the Properties Window at design time in Visual Studio? I mean, like the Opacity property of a Windows Form.

How to add % symbol at the end of each integer to represent a string in textbox.
When running code analysis on my project, I receive the following message:
CA1051 : Microsoft.Design : Because field 'ClassName.VarName' is visible outside of its declaring type, change its accessibility to private and add a property, with the same accessibility as the field has currently, to provide access to it.
Public VarName As String to this:Public Property VarName As String
I don't understand why the Property keyword is so important in this particular case. Can anyone provide an explanation as to why changing this member to a Property makes a significant difference to code analysis?
As the title of the question, I need to validate regex using the following values:
(Maximum 2 decimal places, and 9 integers) with an optional percent symbol.
Valid:
10%
0%
1111111.12%
15.2%
10
2.3
Invalid:
.%
12.%
.02%
%
123456789123.123
I tried:
^[0-9]{0,9}([.][0-9]{0,2})d[\%]{0,1}?$
But It does not work as I want.
I have a form where I have created a custom property, DataEntryRole, and set its Browsable attribute to True, as shown:
<Browsable(True)> _
Public Property DataEntryRole() As UserRole.PossibleRoles
Get
Return mDataEntryRole
End Get
[Code]...
When I view the designer for my form, DataEntryRole doesn't appear in the property box. I assume that it should appear if I were to create another form that inherited from this base form, but that's not what I want. I want this property to show up in my current form.
I have a class where it's problematic to relay on the properties being serialized in alphabetical order at design time.In other words, property Z must be serialized before property A.The problem arises because property property Z clears property A whenever it changes - which happens in InitializeComponent.I work around this problem by setting a FirstTime flag, but that seems messy.
View 2 RepliesIn my never ending search for more knowledge, I have come across Partial Classes. I was wondering if some of the kind people who actually understand the uses could explain some of them to me. Now I know that when we create a form that we actually create a partial class which the generator rewrites when we add a control or change a property at design-time, and this allows us not to have to worry about setting up the controls ourselves.

I have a class that has a readonly collection property - Its a list of extender providers that have been applied to the control.I've implemented a simple property descriptor for the collection so that the property can be expanded in the property grid to examine each entry.
When I select an extender provider and set it to false, I remove it from the collection. The GetProperties method of the type converter is requeried and the property grid refreshes.However, when I set an extender provider to true, and thus add it to the collection, GetProperties is not requeried.
Somehow, the property grid is making a distinction between adding to and removing from the collection. Or alternativly, its refreshing when an extender provider is added, but not when one is removed.

I am creating a User Control where I have a property called Items. Items is of type LibraryPanelBarItem Collection (custom class) which contains a collection of LibraryPanelBarItem objects. I would like to be able to add these at design time by using the Collection editor that VS uses for adding things such as treenodes/listviewitems. Ideally I would also be able to declaratively add them to the html syntax. I can get the Items property to show up but I get no intellisense to add the items between the opening and closing tags.

View 1 Replies(I've answered the question below with a hack. I'm fairly confident in it unless MS change the way that codedom serializers the designer code.)ETA2:I've worked out what is going on. I wondered why sometimes it would work and not others. It boils down to the name that I give to the internal property and the collection.If I rename the property 'Annoyance' to 'WTF', it will serialize correctly because 'WTF' is, alphabetically, after the name of the collection - 'InternalAnger'.It looks like the serializer is creating instances of objects alphabetically and needs my internal property to be created by the time it comes to create the collection.I can fix this with a rename, but that's a hack and I fear that writing a custom serializer is a big job - which I've never done before.ETA: Jesus, I'm sick of this. This problem was specifically about persisting an interface collection but now on further testing it doesn't work for a normal collection. Here's some even simpler code:
Public Class Anger
End Class
Public Class MyButton

i am working on this exercise where i have to find suburbs with minimum and maximum percentage POS (public open space).i manage to get the minimum and maximum but i need a way to allow for two or more suburbs with same minimum or maximum..for example three subrubs ( suburb A, suburb B, and suburb C) all has same POS of 2%, then i need to list the three in the list box as minimum with subrub name(from my code i can get only one) with the maximum values as well( allow two or more suburbs with same maximum in a similar way)..below is the code.. i have removed some codes to make it read easy whi are not relevant.. i got POS percentage correct and i wanna start from there..

I searched on the forum / Internet for the solution how a PropetryInfo object (of a Public property) can reveal if it has a Private Protected Setter ... it was all in vain .... all help I found was about how to "Set" value of a public property having a Private Setter.I would like to know if I have a PropertyInfo object of a public property, how would I know if its Setter is Non Public?
I tried, in a exception handling block, where I did a GetValue of the PropertyInfo object and then called SetValue by setting the same value back... but to my surprise it worked well and didn error out.

What is a public read only property?If you're not living on the edge, you're taking up too much room
View 2 RepliesWhat is the purpose of Public property? why would i do this instead of just doing Public abc as string? [code] Because you may want to do data validation on it before assigning the value to the Private variable. Because you might want to raise an event when the value in the Private variable changes. Because you might later want to make it a ReadOnly property.

Return Me.Statusbar1_LastChecked.Text[code]....
Now when I run the code, the msgbox shows the current text and then the new text. BUT the actual text in the StatusBar remains unchanged.
Is there any way I can put Public Properties on a single line in VB.NET like I can in C#? I get a bunch of errors every time I try to move everything to one line.

is there a way to have the Get part of a property available as public, but keep the set as private?Otherwise I am thinking I need two properties or a property and a method, just figured this would be cleaner.

View 2 RepliesI have a listbox binded to a list of objects. For each list item I wanted to have a rectangle whose fill color is determined by a few properties of the binded object. So I did the following:
Made sure INotifyPropertyChanged was implemented on my object.Created a class to expose the properties I am interested in as attached properties.Binded the properties of the object to the attached properties of the rectangle Created a style that uses triggers to set the rectangle fill based on attached properties.
This works, but only the first time the property of the object changes. After that, the attached properties do not seem to be receiving notification when the data object's property changes. I have double checked and my data object is raising the INotifyPropertyChanged event.
<Rectangle Style="{StaticResource RecordStateRectangleStyle}"
Width="10" Height="10" Stroke="Black"
local:RecordAttachment.RecordState="{Binding Path=RecordState}"
local:RecordAttachment.IsDeleted="{Binding Path=IsDeleted}" />
