Excel add-in won't load when opening Outlook attachment

Hey everyone. I've run into a situation where my Excel 2010 automation add-in won't load when opening an Excel file as an attachment. More specifically, only in the situation where I have Excel already opened (and the add-in running fine) and then try to open the Excel attachment. 

My LoadBehavior is set to 3 and the add-in runs fine in all other situations. I should note that this isn't on my development machine, but a user's computer running Excel 2010 and Windows 7. Could this be as simple as telling Windows to open Excel files in the same instance? 

thanks!

Hi,

there is a way to open a mail item from a path to a .msg file.

var mail = Globals.ThisAddIn.Application.Session.OpenSharedItem(path) as Outlook.MailItem;


I would like to know if it is possible to detect the path of a mail item which was opened from a .msg file?

ribbon load event, thisAddin startup event, why does the firing order of these events change?

So , during the last few days i've developed a small prototype for Outlook 2010, using VSTO. it works fine so far, no problems. I had assumed that, first of all, the entry point of any custom addin for office was the startup event inside the thisAddin class. So, it was here where i would do all the usual security/user profile stuff (i.e: I'd check the current identity user, query some databases where we store roles/permissions etc, checking what that user is/is not allowed to do, and load some custom security object). Once i had this object loaded in the addin startup event, id check for it on any ribbon load event, enabling or chainging the visibility on the different controls.

Now, i have to migrate this prototype to word 2010. To my surprise, the chain or events is the opposite: ribbon load events are being fired first of all, and finally comes the startup event in thisAddin.

What could be causing this?

Thanks

.vsto file not getting invoked for Outlook 2013 addin

hi,

I just migrated our custom signature addin for Outlook 2013 to VS 2013 and used InstallShield for deployment.

Everything seems to get created like registry key and all the files under program files:

Manifest entry:file:///C:\Program Files\[custom app directory]\Office.Outlook.AddIn.EmailSignatures.vsto|vstolocal

and I have all the relevant files including the .vsto in C:\Program Files\[Custom App Directory]

The issue I'm facing is the add-in does not get invoked when I start Outlook 2013. I've to manually go in and invoke the .vsto and then it add the Custom Add-in.

One thing I noticed when I invoke the .vsto I get the following prompt 'cause of the certificate, but I've already installed the certificate. I'm not sure if this the cause of the add-in not getting installed on its own. Is there some way to get rid of this prompt ?

thanks.

Excel 2013 Can't change height of ChartArea

April 28, 2014, 12:32 pm

Hi,

I've inherited an Excel 2007 solution and am working to update it to work in Excel 2013. It's a Template-level solution using C# and running in Visual Studio 2013.

I haven't done a lot with Excel, so forgive me if this is a basic question.

In my code, I create a chart and place it on a ChartSheet based on a ChartTemplate that's stored in the .xlst file.  Then I try to adjust some of the settings of the chart's ChartArea.  However, when I try to adjust the height with this line of code:

newChart.ChartArea.Height = 300;

I get this exception:

System.ArgumentException: The shape is locked and cannot be resized.
   at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)
   at Microsoft.Office.Interop.Excel.ChartArea.set_Height(Double value)

If I manually do the same steps, once I move a Chart from a regular worksheet to a ChartSheet, the size options are greyed out. This doesn't happen in Excel 2007.

Do you have any ideas for a work-around?

We distribute an Excel document customization that uses the VSTO 4.0 runtime.  It has installed successfully on thousands of customers' computers, but one customer reports that the runtime fails to install.  He has provided a setup log, which I'm including below, but it doesn't provide much detail ("Exe (c:\e90d9681e1814a377c00\vstor40\vstor40_x64.exe) failed with 0x80070643 - Fatal error during installation.").

Is there some way to gather more information that would help diagnose this problem?  I don't know what to look at.

Please note that the customer is attempting to install Visual Studio 2010 Tools for Microsoft Office Runtime,not Visual Studio or the .NET Framework.

Thanks,
Tony

Reproducable with Windows XP - ... and Excel 2007 - ...:

  1. I do open Excel and create two or more new workbooks
  2. I do show a modal dialog, let's say via "MessageBox.Show" I open "notepad" and maximize its window
  3. I try to reactivate one of the excel workbook windows via the windows taskbar
  4. I expect: Excel will come up with my modal MessageBox to appear on top
  5. The actual result is: Neither the MessageBox nor any of the Excel workbooks comes up, when you click a workbook item in the windows taskbar!

range.Value2 = myArray is Honoring Autofilter! Help!

My code is working great and fast.  I grab a range...

                Excel.Range dataRange = Globals.ThisAddIn.Application.ActiveWorkbook.Names.Item(rangeAddress).RefersToRange;

get the values into an array...

                object[,] myValues = (object[,])dataRange.Value2;

Manipulate them, and then write them back with...

                    dataRange.Value2 = myValues;

That is, it all works until autofilter screws things up.  It seems Value2 is skipping the rows that are auto-filtered, which is HORRIBLE, since auto-filter is really just for display.  The kick in the teeth is, that the dataRange itself STILL comes back the correct size as it is WITHOUT the autofilter, so it's not even consistent in that regard!

How can I manipulate my sheet values efficiently (ie, without writing cell by cell) with autofilter on?

Thanks

C# To Create A SQL Server Connection in Excel

I know the syntax to connect to access and link in a query to make the worksheet refresh the query.  But how can I use C# to create a connection to SQL Server, embed a SQL statement into that worksheet and save the connection within the workbook so that the connection/sql statement can be refreshed from within Excel?
For example, if I record an Excel Macro with the steps this is the output, but I can not translate to C#

With ActiveWorkbook.Connections( _"Brimstone TestDB TestTable").OLEDBConnection
        .BackgroundQuery = True
        .CommandText = Array("Select * From testTable")
        .CommandType = xlCmdSql

Hi friends,

My Office 2010 + VS 2010 were going on good enough. Unfortunately the day I had MS-Office 2013 installed the moment I start to debug any project with an F5 upcomes the message:

You cannot debug or run this project, because the required version of the Microsoft Office application is not installed.

How can I simply create an Excel 2010 Add In from the VSTO templates available for the same in the VS 2010, although I have Office 2013 installed?

Please see if you can help.

Thanx in advance.

How can I collapse the entire ribbon when editing a new mail message?

May 1, 2014, 11:50 am

I am trying to automatically collapse the ribbon when a message compose window is opened.  The ribbon can be collapsed by the user by typing Ctrl + F1.  If this were an Add-In for Microsoft Word, I think this would be accomplished by executing

Globals.ThisAddIn.Application.ActiveWindow().ToggleRibbon();

However, since this is an Outlook Add-In it appears to be more difficult.  I want this to be done when the compose window is first opened so I have added an Activate event handler on the inspector.  From within the Activate event handler I am trying to execute this code:

Microsoft.Office.Interop.Word.Document wd = inspector.WordEditor as Microsoft.Office.Interop.Word.Document;
Microsoft.Office.Interop.Word.Window w = wd.ActiveWindow as Microsoft.Office.Interop.Word.Window;

if (w != null)
{
	w.ToggleRibbon();
}

Unfortunately I get an exception on the second line:

This object model command is not available in e-mail.

How can I collapse the ribbon when a new mail compose window is opened?

Thanks.

Alt+Tab causes CustomTaskPane to be shown on the Wrong PowerPoint Window

December 12, 2013, 4:31 pm

We are seeing a behavior in PowerPoint that causes custom task panes to be displayed on the wrong PowerPoint window. This behavior can be replicated by having two PowerPoint window open and Alt+Tabbing right after clicking a ribbon button that adds a custom taskpane. Alt+Tab sets the focus on the second PowerPoint application where the custom task pane appears, even if we passed in the DocumentWindow we Alt+Tabbed from to the CustomTaskPanes.Add() call. The DocumentWindow is retrieved through the ribbon button via IRibbonControl.Context as DocumentWindow.

We also tried passing in a DocumentWindow directly from the PowerPoint.Application.Windows[n] collection, resulting in the same behavior described above.

It seems that PowerPoint is relying on ActiveWindow internally rather than the DocumentWindow that was passed in the CustomTaskPanes.Add() call.

Word and Excel behave normally the custom task pane is displayed in the correct window after an Alt+Tab. We are passing in the respective objects to CustomTaskPanes.Add as described in http://msdn.microsoft.com/en-us/library/bb608620.aspx

Thank you.

VSTOInstaller /silent not supported

We currently have a number of users with an OLD add-in for Project that needs to be removed. I'm trying to use VSTOInstaller to remove the add-in through SCCM, but it wasn't built with support for the /silent option. Is there any way around this after the fact? Or any other methods I could possibly use to automate the uninstall from users where it's currently installed without prompting them?
