问题 Could anyone help me get the first tab idMso value of an opened Outlook item window? I need to dynamically set it in a ribbon xml file, since I figured out it would be redundant to add each item window into the xml code. If anyone has an existing solution to share, that would be great. Thanks 回答1: Solved it :) Just edit the return string from the GetCustomUI on runtime, but trap the explorer item first Public Function GetCustomUI(ByVal ribbonID As String) As String Implements Office

问题 How to add a child node to a specific node in treeview? Say I have "Item1" in treeview already, how do I add "SubItem1" to "Item1" as it's child node? I know its probably really simple, but i tried lots of stuff, i just cant get it working. 回答1: Adding child node to parent (non-selected) First use Find() to get a reference to the parent node.

问题 What is the difference? I always use ByVal, but, I don't really have a good idea of when should I and when not... 回答1: If you pass in a reference, when you modify the value in the method, the variable in the call site will also be modified. If you pass value, it's the same as if another variable is created at the method, so even if you modify it, the original variable (at the call site) won't have its value changed. So, indeed, you should usually pass variables as value. Only pass as
