问题 I am new to VSTO VB.Net programming. and I am developing a word application level Addin and want to trap keypress event. I have tried various codes of hooking but none is working. I want to use application level hook using WH_KEYBOARD instead of WH_KEYBOARD_LL . The following code which I have tried traps just one key stroke after that it stops. Moreover I could not understand where to put trap the keystrokes. How would I use the following for handling key events. Public Event KeyDown As

问题 I want to install vsto addin based on the excel version (32 bit or 64 bit). I am planning to bundle both 32bit and 64 bit msis and install one by determining the excel version. I am able to find this link to detect whether 2010 office is 32 bit or 64 bit by using registry. Detect whether Office is 32bit or 64bit via the registry But i want to check for excel 2007 and 2013 whether they are 32 bit or 64 bit. Is it possible to detect them via registry. 回答1: First, look for the installed version

问题 Sorry for the length of this, In the past I've been asked before to included everything I've tried when asking these sort of questions. I'm writing a Word Add-in and need to make changes to the document that I cannot achieve using the Word object model. Therefore, after the document is save to disk, I need to capture that event, close the file, do what I need to do and reopen it. (I know, not elegant, but that's what I have to work with.) Word has Before Save and Before Close, but no after

问题 We have a VSTO application-addin (not a document-addin) for Excel, and we want to expose an event to VBA code so that the VBA macro can do some action when this event fires in the addin. How can I get the VBA code to be able to subscribe to an event defined in the VSTO application-addin? I'd think that since the addin is loaded in the Excel process, this shouldn't be too tricky, but haven't found a way yet. BTW, using VS 2008 and Excel 2007. Thanks! 回答1: VSTO is not a DLL that can generally

问题 I have a button on an Excel sheet which starts a new thread to do some processing. If I want to make any changes to Excel (e.g. write data to a cell using Worksheet.Range("A1").Value = "info"; ), I think I must use the main UI thread. How can this be done? Typically in Winforms I would call Invoke on a control, but the Excel.Application or Worksheet or Range objects don't have an Invoke method. 回答1: That work doesn't 'need' to be done on the UI thread, .net will marshal the call for you, but

问题 Background: I have an extensive set of specialized VBA macros used in Word for document formatting purposes. In Word 2003, these macros were activated from a customized toolbar. I have recently transitioned to Word 2007 and would like to be able to run these existing VBA macros from a new Word Ribbon created with VS 2010. I have created a Ribbon; however, I cannot figure out how to call the existing macros from the new Ribbon buttons. Question: How do I call the existing VBA macros, which are

问题 I've got a minimal VSTO Addin for Outlook 2010 with a ribbon. My only goal is to display a ribbon (created via designer) with no functionality. From what little I can tell from MSDN ribbons should just automatically be displayed by default, perhaps with tweaking ControlIdType/CustomId properties for tabs. Alas, tweaking these properties does nothing -- Outlook loads and displays no tab. A simple message box displayed in the ribbon loader reveals it never is triggered. Additionally, I haven't

问题 I cannot seem to think of a way to correct the error mentioned in the title and was looking for some ideas on what should be done. I am trying to read the rows of a excel spreadsheet into an object. The first time it loops I have no problems because row 1, column 1 and row 1 column 2 have data in them. But when it gets to row 2, column 1 and row 2 column 2 it falls over with the above error because those cells in spreadsheet are "empty" I just cannot work out where I can put some "if null"

问题 Visual Studio 2012 does not appear to support Office 2007 (it only has project templates for Office 2010). If I want to create an add-in compatible with Office 2007, do I need to use Visual Studio 2010, or is there a simple way to do it with VS 2012? If there is a way to do it in VS 2012, are there any restrictions/advantages, etc. in doing so? 回答1: You can get VS 2012 working with Office 2007 . First create an Outlook 2010 Add-In and modify the project file ( .csproj ) so that it will open
