Hi all

I m facing a problem with creating Instance of Categories Interface.
I copy this code from MSDN and try to execute in vb.net application.

Dim instance As _Categories
Dim Name As String
Dim Color As Object
Dim ShortcutKey As Object
Dim returnValue As Category

returnValue = instance.Add(Name, Color, ShortcutKey)


But it is showing Error "Object reference not set to an instance of an object."

Here is the link of msdn. Can anyone solve this problem and give me suggestion with the help of code...

推荐答案

实例不是设置为任何值，这就是您收到错误的原因.
请尝试以下代码:

Dim instance As Categories<br />Dim Name As String<br />Dim Color As OlColor<br />Dim ShortcutKey As OlCategoryShortcutKey<br /><br />Dim returnValue As Category<br /><br />Dim f As NameSpace<br />Set f = Application.GetNamespace("MAPI")<br />Set instance = f.Categories<br />Color = olColorFuchsia<br />Name = "MyCategory"<br />ShortcutKey = olCategoryShortcutKeyNone<br />Set returnValue = instance.Add(Name, Color, ShortcutKey)

instance is not set to anything, that''s why you get the error.

Try this code:

Dim instance As Categories<br />Dim Name As String<br />Dim Color As OlColor<br />Dim ShortcutKey As OlCategoryShortcutKey<br /><br />Dim returnValue As Category<br /><br />Dim f As NameSpace<br />Set f = Application.GetNamespace("MAPI")<br />Set instance = f.Categories<br />Color = olColorFuchsia<br />Name = "MyCategory"<br />ShortcutKey = olCategoryShortcutKeyNone<br />Set returnValue = instance.Add(Name, Color, ShortcutKey)
