I can't seem to any useful information on the net either...

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 created a little demo application which is able to create a meeting request by using the Exchange WebService (EWS). I would also like to add some custom properties to this item but up to now I have only found examples which use the Exchange Managed API, which I won't use. There must be a way to create these properties by only using EWS... Does anybody know how and can provide a little code example?
View 1 Replieshow to create my own custom property that is an object but that allows a string to be passed in to the property grid to configure it.For example, with a font type property you can type "Microsoft Sans Serif, 18pt" into the property grid and it will create the appropriate font structure and fill it.
View 5 RepliesI want to create a custom control (let say textbox), after build, when I place that custom control on a form, all the properties for the default textbox are available.

2- Is there a Wizard or custom tool for creating custom control or I had to do every thing by coding?
I did some googling and found this forum post, and here is what I needed to do:

View 1 RepliesI am trying to work out a method to reset the image property of my picturebox on the fly.
I am able to load the original image from a file. But i want to save a clean copy of it before i draw on it. Between drawings i want to be able to reload it.
Here is what i have tried
Dim img as image
Using OpenFileDialog1 As New OpenFileDialog
With OpenFileDialog1

the code does not seem to work it just freezes. Im not sure exactly whats going on with it.
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?
I am just wondering how i can create a picturebox array like i could when i copied and pasted another picturebox in VB6 and it asked me if i want to add them to an array. Doing so made them code like this:

I'm attempting to create multiple PictureBox controls. This is as close as I've got this thing to work:
vb.net
Dim Obj(6) As PictureBox, i As Byte
Dim Pics() As Image = New Image() { _
[code]....
However, it gives me this error on run-time:
Quote:
Object reference not set to an instance of an object. on the line "Obj(i).Image = Pics(i)".It would work if I was able to create a 'new' instance: Dim Obj(6) As New PictureBox, however apperntly:
Quote:
Arrays cannot be declared with 'New'.I am pretty sure that my image resource files are 'instances' of objects'' because the code works fine when every statement is written out separately (no arrays).
I have made a usercontrol, it has a property that has a PictureBox datatype. When the usercontrol is dropped on a Form from the toolbox, I want the picturebox property (in the property window) to be showing all the picture boxes (names) that are on the form as a dropdown so I cant select them. How do I do that?

I'm trying to create a small game in VB2010. The gameplay is as follows:
civilians would walk/stand in a room/street and suddenly an evil character would pop from the ground/wall. This evil character would suddenly vanishes too. So, the player has to shoot it to kill the character. The evil character, civilians, etc. would be random. Also, there would be sound effects too. That is the popping up of the evil character, it's voice, the civilians voice, etc. I'm trying to make it as simple as possible but without degrading the quality of the game play. I think, I could somewhat create the graphics for the characters, scenes, etc. and can get the sound effects recorded.
So, the difficult part is,[ ] how could I make it a smoother for playing the game ?
[ ] what would be the best way to do animations ?
[ ] Creating a GIF and placing it in the picturebox and moving it ?
[x]how to play the music in background and at the same time play sound effects on certain instance ?
I 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}" />

I have created a custom class, which contains a panel and a label on it. I added to this class a pcaption property, which holds the label text. This property is browsable and I can change its value.But when I drag the custom control to the form and change the pcaption property, it has no effect. Even the <Defaultvalue> has no effect. Why?
Here is the class code:

Private panelcaption As String

Color values are unimportant, you can change it.
