Hi,
I have code that works in Outlook (Office) 2013. I have added a custom context menu item to the right click of an attachment in a received email. The code looks like this:
private void adxCustomSaveFileButton_OnClick(object sender, AddinExpress.MSO.IRibbonControl control, bool pressed)
{
AttachmentSelection attachmentSelection = null;
attachmentSelection = control.Context as AttachmentSelection;
...
This code works fine in 2013, but the attachmentSelection variable is null in 2016. I am using adxnet-v703-b4061-vs-pre if that matters.
How can I get an AttachmentSelection in 2016?
Thanks,
Jeff |

Hello Jeff,
I would start with checking if controlContext is not null and its type is AttachmentSelection.

yeah, it is not null, and it's not an AttachmentSelection type, but I don't know what type it actually is. Here is what I do know (followed by output from the immediate window):
1. control.Context is NOT null:
control.Context
{System.__ComObject}
Native View: To inspect the native object, enable native code debugging.
Dynamic View: Expanding the Dynamic View will get the dynamic members for the object
2. control.Context is NOT of type AttachmentSelection:
control.Context is Microsoft.Office.Interop.Outlook.AttachmentSelection
false
3. Adding a reference to Visual Basic and testing the type of the underlying COM object says it's an Explorer, but it won't cast to one:
Microsoft.VisualBasic.Information.TypeName(control.Context)
"Explorer"
control.Context is Microsoft.Office.Interop.Outlook.Explorer
false
((Microsoft.Office.Interop.Outlook.Explorer)control.Context)
'((Microsoft.Office.Interop.Outlook.Explorer)control.Context)' threw an exception of type 'System.InvalidCastException'
Is this something you can test/confirm?
I am also having other similar issue with regions. adxOlFormsCollectionExplorerShare.GetForm(explorer); is also returning null in Outlook 2016 (but I can start another thread for that if you like).
Thanks,
Jeff |

Jeff,
In what scenario do you get this? I suppose you right-click an attachment in the Reading Pane and then select your item in the context menu the IdMso of which is ContextMenuAttachments. Correct?

Andrei,
Not sure I totally follow all of that. Yes, I right click an attachment in the reading pane. I select my item in the menu which fires the click event.
this.adxCustomSaveFileButton.OnClick += new AddinExpress.MSO.ADXRibbonOnAction_EventHandler(this.adxCustomSaveFileButtonButton_OnClick);
I should note that in Outlook 2016, you don't actually right click (you can, but it just opens the menu). What I mean by this is attachments now look like a button with a drop down arrow instead of just a file that needs a right click.... Don't know if that's relevant or not...

Thank you for the screenshot. I'll check this scenario on one of the test machines tomorrow.

Hello Jeff,
The code below reports attachmentSelection.Count is 1 when I click my button in Outlook 2016 build 16.0.4266.1003 32bit.
private void adxRibbonButton1_OnClick(object sender, IRibbonControl control, bool pressed) {
object context = control.Context;
if (context == null) {
System.Diagnostics.Debug.WriteLine("!!! adxRibbonButton1_OnClick. context == null");
return;
}
string typeName = Microsoft.VisualBasic.Information.TypeName(context);
System.Diagnostics.Debug.WriteLine("!!! adxRibbonButton1_OnClick. context is " + typeName);
if (typeName == "Explorer") {
Outlook._Explorer explorer = context as Outlook._Explorer;
if (explorer == null) {
System.Diagnostics.Debug.WriteLine("!!! adxRibbonButton1_OnClick. explorer == null");
} else {
System.Diagnostics.Debug.WriteLine("!!! adxRibbonButton1_OnClick. explorer != null");
Outlook._AttachmentSelection attachmentSelection = explorer.AttachmentSelection;
if (attachmentSelection == null) {
System.Diagnostics.Debug.WriteLine("!!! adxRibbonButton1_OnClick. attachmentSelection == null");
} else {
System.Diagnostics.Debug.WriteLine("!!! adxRibbonButton1_OnClick. attachmentSelection.Count = " + attachmentSelection.Count.ToString());
Marshal.ReleaseComObject(attachmentSelection);
}
}
}
Marshal.ReleaseComObject(context);
}

Andrei,
Thanks for the reply. Seems that AttachmentSelection was added to the 2016 dll's for the Explorer object. I had to upgrade to the 2016 office dll's to get it to compile. It does work though. I think the other issues I am having are related to similar issues. I hope the 2016 dll's are backward compatible because I'll have to use the same references against customers running older versions of Outlook.

Jeff,
As far as I know, the Explorer.AttachmentSelection property was introduced in Outlook 2010. I strongly recommend using interops for the lowest Outlook version that you need to support because calling a member available in an Outlook interop but missing in the Outlook object model will end with an exception and crash. If however you need to call a member which is available in the host's version loading your add-in but missing in the interop that you use, you use late binding. See also https://www.add-in-express.com/creating-addins-blog/2010/03/16/interop-assemblies-late-binding/.
