Context Menu on items

Hello,

I developed an add-in to show a Context Menu on item right-click.

This was developed using Extensibility.IDTExtensibility2 interface in
Visual Studio, using the Microsoft Office 10.0 Library.

The add-in works fine on Office XP...any time I right-click an item,
it shows a context menu with an added button.

The weird thing happens on Office 2007... when I first right click the
context menu shows correctly. Then if I right-click immediately on
other items the menu doesn't always shows up with the added
button...instead if I wait at least three seconds between each right
click the context menu ALWAYS shows up correctly.

What could it be? I tried logging and debugging but I cannot solve the
issue.

Thank you,
Ivan

Here I post a snippet of my code:

Private Sub ActiveExplorerCBars_OnUpdate() Handles
_ActiveExplorerBars.OnUpdate

If _IgnoreCommandbarsChanges Then Exit Sub

If _ActiveExplorerBars.Item("Context Menu") IsNot Nothing Then
If _outApp.ActiveExplorer.Selection.Count > 0 Then
If _outApp.ActiveExplorer.Selection.Item(1).Class =
Outlook.OlObjectClass.olMail Then
AddContextButton(_ActiveExplorerBars.Item("Context
Menu"))
End If
End If
End If

End Sub

Searching Google I found this guy who find out the cause of the
problem:

"If a user has the reading pane enabled in a folder and they right-
click on a mail item while the reading pane is still loading data,
then the custom item added to the context menu will not appear. "

This is real...deactivating the reading pane it works fine on Outlook
2007...

So... anyone has a solutions to this?

Thank you very much,

Coding for context menus with any version of Outlook prior to Outlook 2007
is a hack. For Outlook 2007 you have all the new context menu events and
working with the context menus is supported by MS.

Outlook 2007 is slower than earlier versions and that's what's causing the
problem there.

What you might try is compiling a DLL that is compiled using the Outlook
2007 object model and loading it when you detect Outlook 2007. In that DLL
you pass in the trusted Outlook.Application object and instantiate the
Application.ContextXXX events you want to handle where ContextXXX represents
one or more of the available context events.

Something like that would allow you to handle the events correctly for
Outlook 2007 while still using the hacks needed for versions prior to
Outlook 2007.




Searching Google I found this guy who find out the cause of the
problem:

"If a user has the reading pane enabled in a folder and they right-
click on a mail item while the reading pane is still loading data,
then the custom item added to the context menu will not appear. "

Hello,
Click to expand...
I developed an add-in to show a Context Menu on item right-click.
Click to expand...
This was developed using Extensibility.IDTExtensibility2 interface in
Visual Studio, using the Microsoft Office 10.0 Library.
Click to expand...
The add-in works fine on Office XP...any time I right-click an item,
it shows a context menu with an added button.
Click to expand...
The weird thing happens on Office 2007... when I first right click the
context menu shows correctly. Then if I right-click immediately on
other items the menu doesn't always shows up with the added
button...instead if I wait at least three seconds between each right
click the context menu ALWAYS shows up correctly.
Click to expand...
What could it be? I tried logging and debugging but I cannot solve the
issue.
Click to expand...
Thank you,
Ivan

Ok, very smart.

What is the best way to detect the Outlook version?

Thanx,
Ivan

Coding for context menus with any version of Outlook prior to Outlook 2007
is a hack. For Outlook 2007 you have all the new context menu events and
working with the context menus is supported by MS.

Outlook 2007 is slower than earlier versions and that's what's causing the
problem there.

What you might try is compiling a DLL that is compiled using the Outlook
2007 object model and loading it when you detect Outlook 2007. In that DLL
you pass in the trusted Outlook.Application object and instantiate the
Application.ContextXXX events you want to handle where ContextXXX represents
one or more of the available context events.

Something like that would allow you to handle the events correctly for
Outlook 2007 while still using the hacks needed for versions prior to
Outlook 2007.




Searching Google I found this guy who find out the cause of the
problem:

"If a user has the reading pane enabled in a folder and they right-
click on a mail item while the reading pane is still loading data,
then the custom item added to the context menu will not appear. "

This is real...deactivating the reading pane it works fine on Outlook
2007...

So... anyone has a solutions to this?

Thank you very much,
Ivan

Outlook.Application.Version. It's a string so you'd have to parse the
string. I usually look at the 2 leftmost characters, if they are "12" it's
Outlook 2007, "11" is Outlook 2003, etc.




Ok, very smart.

What is the best way to detect the Outlook version?

Ok, so at first I have to load the Outlook 10 library in order to
detect the version and then if it is the 2007 version I load its
library, correct?

Thanx,
Ivan
 
You can't load the libraries it's what's referenced when you compile.

You would create a project to create a DLL and use the Outlook.12 library
for that (Outlook 2007). The main code only references the earliest version
of Outlook you need to support. If that code discovers that
Outlook.Application.Version.StartsWith("12") == true then it loads the DLL
that handles the Outlook 2007 context menus and doesn't instantiate the
CommandBars.OnUpdate() event handler since context menus will be handled
using that DLL.

But the menu item is not being displayed. Please help me get this problem
solved..
 
Did you look at the context menu handler examples at www.outlookcode.com to
see how to handle this? If the examples there aren't in C# they certainly
are in VBA/VB6 and you can translate them into C#.
 
Hi Kan Slovak, Yeah there are examples developed using C#, but not the one I
want for adding context menu item, but Kan I am sure this is the correct
code, but I am unable to see the item. Anyways, can you give me the exact
code in VBA or any other language, Ill convert it to C# and check...
 
private void ThisApplication_OnCBarsUpdate()

When I debug the code I am I came to know the CommandBar Context Menu is in
the seen in the loop, So the inner if condition is never executed. Please
help me understand what is the problem, why dont the Context Menu CommandBar
is not available in the code. Please help it is taking me real long time.
 
Sorry, mistakes in the last post..

Search at outlookcode.com for "context menu" and start looking at the
results. There are a number of VBA examples.
 
The context menu item is only there in the CommandBars collection if you
have right-clicked and are bringing up a context menu. Otherwise the code
should exit without finding the "Context Menu" CommandBar object. It's
certainly there when I run code that looks for it.
