问题 We develop a VSTO plugin for Word and we have the problem that the earliest entry point of the addin is the AddIn_Startup handler. The issue is that this handler is called too late for the AssemblyResolve handler we implemented to find the needed assemblies. I sovled the problem by assigning the handler to the AppDomain.CurrentDomain.AssemblyResolve event in the Addins.Designer.cs class, but as you all know, this code is autogenerated. Is there a way to assign the AssemblyResolve Handler

问题 I develop VSTO solutions for Word and Excel. Since yesterday, for no apparent reason, I am now unable to debug any of my solutions. I face the same symptoms even when I try to debug a new blank VSTO project. When the add-in launches (typically at Excel or Word startup), the following shows up: System.Security.SecurityException: Customized functionality in this application will not work because the certificate used to sign the deployment manifest for ExcelAddIn1 or its location is not trusted.

问题 I want to catch the change event on an AppointmentItem. I use Outlook 2017 for tests. To achieve I use: I attached the events like this: public void AttachEvents() { _CalendarItems.ItemAdd += Item_Add; _CalendarItems.ItemChange += Item_Change; _DeletedItems.ItemAdd += Item_Delete_Add; The Item_Change method looks like this: public void Item_Change(Object item) { if (item != null && item is Outlook.AppointmentItem) { Outlook.AppointmentItem myAppointment = item as Outlook.AppointmentItem; To

问题 I want to replicate the following code from VBA into c# VSTO: M_Script = LoadTextFile(qname, wk) qSource = workbook_path & "\" & qname & ".csv" Dim qry As WorkbookQuery Set qry = wk.Queries.Item(qname) qry.Formula = M_Script Set qry = wk.Queries.Add(qname, M_Script, qSource) wk.Connections.Add2 "Query - " & query.Name, _ "Connection to the '" & query.Name & "' query in the workbook.", _ "OLEDB;Provider=Microsoft.Mashup.OleDb.1;Data Source=$Workbook$;Location=" & query.Name _ , """" & query

问题 From what I understand you need to track Activation and Deactivation of the Explorers. During activation, you need to add SelectionChange event handlers for the current explorer. This seems to work perfectly for single clicks on AppointmentItems. But it crashes the Addin when double-clicking on an appointment series and selecting a single Appointment. Here is the source: On class level private Outlook.Explorer currentExplorer = null; private Outlook.AppointmentItem currentAppointmentItem =

问题 I have a ribbon button that inserts text into an outlook Inspector by modifying the MailItem object based on the recipients in it. The method that gets called on click looks like this: public async void OnTemplateClick(Office.IRibbonControl control) { var templateId = control.Tag; var template = templates.GetTemplateById(templateId); await templateUi.SetTemplate(control.Context, template); } the SetTemplate method looks like this: public async Task SetTemplate(object window, Template template

问题 I am trying to add a menu item to the attachment context menu. The problem is that the item does not show up. I've seen some examples where they say that this code should work: this.Application.AttachmentContextMenuDisplay += new ApplicationEvents_11_AttachmentContextMenuDisplayEventHandler(ThisAddIn_AttachmentContextMenuDisplay); private void ThisAddIn_AttachmentContextMenuDisplay(CommandBar commandBar, AttachmentSelection attachments) { if (attachments.Count > 0) { var cbc = commandBar

问题 I can not find any documentation to verify this or any working examples I want to achieve something like this xml below, but I think this really is not possible. <customUI onLoad="Ribbon_Load" xmlns="http://schemas.microsoft.com/office/2010/01/customui"> <ribbon> <tabs> <tab idMso="TabAddIns" label="Ribbon1"> </tab> <tab idMso="TabAddIns" label="Ribbon2"> </tab> </tabs> </ribbon> </customUI> 回答1: You can have multiple tabs, if you are using exiting tabs then set idMso="exiting tabids"
