I would like to know if it possible to start Workbook connection dialog (excel build-in) from my c# code (excel plugin)?

HiMatej Golob!

What version of Excel are you using?
I tested the following code in Excel 2007.
It displays the Workbook Connections dialog.



Globals.ThisAddIn.Application.CommandBars["Nil"].Controls["&Workbook Connections..."].Execute();


You might also want to take a look at Application.Dialogs although
I'm not familiar which of the enumeration values corresponds to the Workbook Connections dialog.
