Isn’t this what you needed? http://www.abstractvb.com/code.asp?A=1036

Mike,

I think for the most part that’s true. The syntax is the same, but the usage is a little different.

Here’s the code I was working on in both VB and C#

[Bindable(true),Category("Items"),DefaultValue(null)]
public System.Collections.ArrayList TabItems
{
get { return this._tabItems; }
set { this._tabItems = value; }
}

<Bindable(False), Category(“Data”), DefaultValue(Nothing)> Property TabItems() As ArrayList
Get
Return _tabItems
End Get
Set(ByVal Value As ArrayList)
_tabItems = Value
End Set
End Property

The difference is, the C# version compiles and works. The VB one doesn’t. I want use the DefaultValue attribute to set a (duh) default value of null (nothing) on the TabItems property in the designer. What do I pass into the arguments for the DefaultValue attribute in VB? I tried “typeof(ArrayList)” I tried various combinations of GetType(typeof()) and so forth. The MSDN docs couldn’t tell me anything, every example either use boolean properties or string properties. I wanted to see an example of a property with a reference type, besides string, that used the DefaultValue attribute. I still haven’t figured it out, it was easy in C# so I just re-wrote the control in C#. It took about 10 minutes for me to re-write it.

I started out dabbling in VB4 32bit, moved on to VB 5, and started using VB 6.0 while it was in beta. They’ve really screwed up VB, it can’t really be considered a RAD development tool anymore. Hopefully the Whidbey release will go a long ways towards fixing that situation.

Try this:

Default Public Property PropName(ByVal Value As Integer) as Integer
Get
Return _MemberVariable
End Get
Set
_MemberVariable = Value
End Set
End Property

The way to do this is as follows:

For other reference types, simply replace the GetType() value. For example, to set a default value for a string property:
