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?

how 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.

I 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.
1- How to Hide them and only show the wanted property and method?
2- Is there a Wizard or custom tool for creating custom control or I had to do every thing by coding?

View 2 RepliesI am building a code behind page that has a public property (MyDTOItem) which is essentially a DTO object (dtDTOItem) Note: In my code the Get and Set are actually real code (I stripped it for the example).The problem I am having is in the Page_Load event. When I set the .Member1 property of the DTO object the Get code runs and not the Set and therefore the DTO ibject property .Member1 never gets assigned. I figured out that if I add code (MyDTOItem = New dtDTOItem) to the Page_Load event then it will set the value correctly. What I am trying to figure out is how to initialize the property object without having to do it explicitly. It has to be an extended property because I have custom Get and Set code.
Public Property MyDTOItem As dtDTOItem
Get
End Get
Set(value As dtDTOItem)

I've created a custom user control that has several properties. One specifies which database I want the control to access. I want to be able to present the user of the control a drop down from which he can select which database the control will interact with. How do I get the dropdown to work? I can get default values, but have yet to figure out how to get the selectable list.

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?

With VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file

I'm trying to add validation to one of my class properties:[code]The value for the golfer's handicap comes from a oombo box on the form. Even if I have nothing set for this property at runtime, my validation doesn't work. I tried putting the If statement under Get instead of Set, and tried mHandicap = value after an Else in the If statement, but nothing seems to work. I'm working in the dark here and can't find anything suitable online. I was hoping to not go down the path of ReadOnly or WriteOnly properties as I'm not at that stage yet, but does this make a difference for my purposes here? Can anyone guide me as to what I'd need to do from this point? If I've got it right, you can add validation in the class and this means that you then don't need to repeat this validation in the form??

I'm trying use just a user control form to act like the old VB6 picturebox. Mainly, i'm doing this is because a user control form is also a container but i also want it to have an image property. I've done this. The new control does have an Image property but the problem is that the user control form doesn't have an image property but only a BackgroundImage property.I was hoping that there is some way to place the selected image, directly on the surface of the user control and not to it's BackgroundImage property. Here is what is got so far:
Code:
Public Property Image As System.Drawing.Image
Get
Return Me.BackgroundImage
End Get
[code]....
As you can see, for now, i have to use the BackgroundImage property but i want to image to be placed on the controls surface, so that the image can be manipulated, like drawing game tiles on it or image processing. The user control doesn't have a real image property?
I have a For Each block loops through a list of objects, the objects are all instances of a single custom class I have made which has multiple properties.The logic used in this block uses a property of the custom class to do a set action, is it possible to dynamically supply which property it uses in the logic? This will be more efficient and prevent me from having to create this logic over for each property of the custom class.My best guess was that maybe it is possible with reflection, however my searches into reflection have left me more confused.
