Thread: How can i add a button to existing ribbon

Here is an example to add a button to the existing ribbon try this code:

Code:

The idea is to handle the GetCustomUI callback. It fires only the first time
an item type is opened in that Outlook session and passes you a string
ribbonID argument, which is the type of item being opened.

This is a C# example of handling that callback for new mail items:

public string GetCustomUI(string ribbonID)
{
//RibbonID indicates type of Inspector that is about to be
displayed,
//   valid RibbonID values are as follows:
//Microsoft.Outlook.Mail.Read
//Microsoft.Outlook.Mail.Compose
//Microsoft.Outlook.MeetingRequest.Read
//Microsoft.Outlook.MeetingRequest.Send
//Microsoft.Outlook.Appointment
//Microsoft.Outlook.Contact
//Microsoft.Outlook.Journal
//Microsoft.Outlook.Task
//Microsoft.Outlook.DistributionList
//Microsoft.Outlook.Report
//Microsoft.Outlook.Resend
//Microsoft.Outlook.Response.Read
//Microsoft.Outlook.Response.Compose
//Microsoft.Outlook.Response.CounterPropose
//Microsoft.Outlook.RSS
//Microsoft.Outlook.Post.Read
//Microsoft.Outlook.Post.Compose
//Microsoft.Outlook.Sharing.Read
//Microsoft.Outlook.Sharing.Compose

//In this sample only new mail Inspector is handled for a
button.

switch (ribbonID)
{
case "Microsoft.Outlook.Mail.Compose":
// Return the RibbonX markup stored as a resource in the
project
return Resources.CustomRibbon;
default:
{
return String.Empty;
}
}
}


I'm not sure what version of VS you're using or if you're using a shared
addin or a VSTO addin, but you can download the Outlook 2007 templates I
have on my Web site (for VS 2005 for both shared and VSTO addins).

Those have simple XML for adding 2 groups to a custom tab in a new email
message. Each group gets 3 buttons. The templates are in C# and VB.NET (and
VB6). They're at http://www.slovaktech.com/outlook_2007_templates.htm.

For reference you should also download the schemas for Office 2007, you need
those for the correct names for the ribbon UI and to locate a group within
an existing tab or in the Office button groups.

As I mentioned, they're pretty basic (from my book). The XML itself looks
like this (from the VSTO C# sample):

onLoad = "Ribbon_OnLoad" >
insertAfterMso="TabNewMailMessage" >
visible="true">
onAction="CSToggle" getPressed="CSPressed" getImage="CS_GetImage" />
onAction="CSToggle" getPressed="CSPressed" getSupertip="CS_GetSuperTip"
getImage="CS_GetImage" />
getSupertip="CS_GetSuperTip" onAction="CSToggle" getPressed="CSPressed"
getImage="CS_GetImage" />
visible="true">
getSupertip="CS_GetSuperTip" onAction="CS_Action" getImage="CS_GetImage" />
onAction="CS_Action" getSupertip="CS_GetSuperTip" getImage="CS_GetImage" />
