Worksheet Activate event is not firing

-
On a fine day, I found that custom task pane is not appearing on activating a worksheet. I could find no error messages in our log4net log and windows logs. I tried to troubleshoot for a while but nothing worked. 

 Finally, I went back my stable project and started comparing the code. It's found that the following line was commented out. 

                  Globals.Factory.GetVstoObject(projectPlanSheet);

 As soon as I have removed the comments and task pane showed up again. 
I found that GetVstoObject() generates an extended object which gives access to application level events. Also, check out HasVstoObject().  

 A short description about extended object

  • Add managed controls to any open document or worksheet
  • Convert an existing list object on an Excel worksheet to an extended ListObject that exposes events and can be bound to data by using the Windows Forms data binding model
  • Access application-level events that are exposed by Word and Excel for specific documents, workbooks, and worksheets

Recently, I noticed the followed issues in SFDC Ant deployment. Issue 1: Typo in XML <name> metadata data for Web Link Just to reiterate, all the buttons and links created under "Buttons and Links" section of the Object are treated as Web Links . Screenshot from Force.com Migration Tool Guide It should be WebLink, not Weblink. Otherwise, the following error occurs while extracting the package :  package.xml - Entity type: 'Weblink' is unknown. Correct XML is:  <types> <members>Opportunity.Cancel_CheckOut</members> <members>Opportunity.Generate_Deal_Sheet</members> <name>WebLink</name> </types> Issue 2: Unable to deploy entities with special characters Example: <types> <members> User w/Export  </members> <name>Profile</name> </types> I tried to deploy Profile entities with special characters like '-' and '/...

Information Architecture - Setup your term store to scale

-
In this post I am going to put together a list of best practices to consider when setting up a term store in Sharepoint Online. As you may already know term store is collection of term groups. And each term group consists of number term sets. Each term set contains a list/hierarchy of terms. Team group gives the flexibility in terms of access. You can assign permissions to users on their term group, rather than giving them access to the entire store.  Always maintain a corporate/general term group which contains common term sets across organization.  Every group/business unit should have a term group. Pin the terms from corporate term group as required into Business unit term groups.  For example, you plan to maintain list of document types in common term group. Thus, there is a term set created. Marketing department want to use this term set. But, they want to add a few more terms. In this case, you should create another term set in Marketing department term g...
