I wrote C# Add-in using the function "RunThinAnalysis2" of  "SolidWorks Utilites"

gtcocswUtilities swUtil = (gtcocswUtilities)this.theiSwApp.GetAddInObject("Utilities.UtilitiesApp");

if (swUtil != null)

                    {

                        gtcocswThicknessAnalysis swThicknessAnalysis = swUtil.ThicknessAnalysis;

                        int status = swThicknessAnalysis.Init();                              

                        int errorValue = swThicknessAnalysis.RunThinAnalysis2(minValue / 1000.0, 

                                                                (int)gttckResolutionOptions_e.gttckHighResolution,

                                                                (int)gtResultOptions_e.gtResultSaveReport,

                                                                pathFolderThickness,

                                                                true,

                                                                true,

                                                                true);  

          }

This add-in is built up as a dll file, and it works well in SolidWorks

Now, there is a  new issues that I need to use another standalone program to wake up Solidworks and this addin

string SwLoaderPath =  ".\\sldutils\\SwLoaderSw.dll";

string addinLocation = System.Windows.Forms.Application.StartupPath + "\\ThicknessAndSectionAnalysis.dll";

long result2 = swApp.LoadAddIn(SwLoaderPath);

long result1 = swApp.LoadAddIn(addinLocation);

But every time when Solidworks is waken up,the "SolidWorks Utilities"  is not  active, and I have to turn on this option manually before using my Addin.

Is there any method to active  "SolidWorks Utilities"  using C# Solidworks API?
