Using SQL Server Data Tools for VS 2010 and developing an SSIS Package, somehow the Toolbox got closed. NOt sure how. Upon re-oppoening, it was EMPTY. It took me DAYS of anguish and deleting the Toolbox.TBD files and re-installing and repairing and whatever else to try to get those Control Flow and Data Flow elements BACK on the Toolbox.I finally came across a post that mentiioned the difference between the standard VS Toolbox and the SSIS Toolbox. When did that happen?Any why, when I open an SSIS package, does it not open the SSIS Toolbox? VERY Frustrated.
