问题 I'm working on a VSTO tools project for Excel. I'm now in the process of upgrading my machine. My "old" laptop was running Windows 7 x64 with Office 2010 and Visual Studio 2012. My new machine has Windows 8 x64 with Office 2013 and Visual Studio 2012. When opening my solution on VS2012, in the new machine, it gives me an error loading the project: Cannot create the project because the application associated with this project type is not installed on this computer. You must install the

问题 I develop a VSTO addon for Outlook. I sign the addon with a certificate purchased with Verisign Inc. The cert is valid and authorized by a trusted root authority. But when my customers install the addon they are still prompted with "Do you want to install this addon from this publisher?" question. From what I understand Verisign cert is enough to make this go away, am I right? Is this prompt a mandatory in VSTO addon installation? Thanks 回答1: No, the prompt isn't mandatory, but it sounds like

问题 I'm mocking VSTO objects and in one project (I didn't write) it has this code: var listOfSheets = new List<Worksheet>(); var mockSheets = Substitute.For<Sheets>(); mockSheets.Count.Returns(listOfSheets.Count); The Intellisense ToolTip for the mockSheets shows 6 properties: The line with the break point works in this project. However I have the same code in a different project (same references, namespaces, etc.), yet the Intellisense ToolTip for the mockSheets only shows 1 property: I know

问题 I've been stuck for a few hours on this problem : I am developing a PowerPoint AddIn in C# and I want to use a macro from another AddIn which is a PPAM file. The PPAM file is installed and enabled. In the Application reference I found that I need to use the Application.Run method but I cannot get it working ( nothing happens )... Here is my code: Globals.ThisAddIn.Application.Run("PPspliT.ppam!PPspliT.PPspliT_main", null); PPspliT.ppam is the installed AddIn ( which is located here : C:\Users

问题 I've tried 3 different code samples and they all fail. Here's the code from a MSFT employee (How to show a context menu on a range), the other two samples have pretty much the exact same code: private void ThisAddIn_Startup(object sender, System.EventArgs e) { CommandBar cellbar = this.Application.CommandBars["Cell"]; CommandBarButton button = (CommandBarButton) cellbar.FindControl(MsoControlType.msoControlButton, 0, "MYRIGHTCLICKMENU", Missing.Value, Missing.Value); if (button == null) { //

问题 I'm trying to develop an MS Office Addin in C# .Net and I don't have access to Visual Studio. Instead I'm using SharpDevelop as my IDE, (but my question is equally relevant to anyone developing using any other IDE or compiling from the command line...) I've done a bit of searching for guides on how to develop AddIns, but they all seem to require Visual Studio and follow these steps: Install the Interop Assemblies Create a Visual Studio .Net Project ( I'm unable to do this bit ) Extend the VS

问题 I use the following VB.NET (VSTO) code to add a shape in MS-Word, Dim app As Word.Application = Globals.ThisAddIn.Application Dim doc As Word.Document = app.ActiveDocument Dim left As Single = CSng(Convert.ToDouble(app.Selection.Information(Word.WdInformation.wdHorizontalPositionRelativeToPage))) Dim top As Single = CSng(Convert.ToDouble(app.Selection.Information(Word.WdInformation.wdVerticalPositionRelativeToPage))) Dim shape As Word.Shape = doc.Shapes.AddShape(1, left, top, 225.1F, 224.5F)

问题 Hope you can help me. I am looking forward to programming my first MS Access AddIn with Visual Studio 2015 (a Ribbon-Bar as VSTO), but not having started I have to stop already. Visual Studio provides templates for almost every office product, but MS Access. I heard it is possible to "change" for example the Excel VSTO-Template so it can be used to develop an MS Access Ribbon. Does anyone know a good instruction how to handle this? How are you developing VSTO for MS Access? Thanks for your

问题 I work on a VSTO in c#. When I click on button I save attachment in a folder. My problem is : when I have a rich email with an image in the signature, I have a element in my attachment. But I don't want save that image. Outlook (application) hide this attachment in the area attachment !
