Disable the error highlighted elements are joined but do not intersect

[Anonymous]

When I want to join wall and structural framing it shows error that highlighted elements are joined but do not intersect. What this error mean?

And if I want to disable this error and create own taskdialog box and display my error how I do this?

this is my code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using Autodesk.Revit.Attributes;
using Autodesk.Revit.DB;
using Autodesk.Revit.UI;

namespace JoinGeometry
{
[Transaction(TransactionMode.Manual)]
class WBjoin
{
bool check;
public Result Execute(ExternalCommandData commandData)
{
UIApplication uiApp = commandData.Application;
// UIDocument uiDoc = uiApp.ActiveUIDocument;
// Application app = uiApp.Application;
// Document doc = uiDoc.Document;
UIDocument uidoc = uiApp.ActiveUIDocument;
Document doc = uidoc.Document;

//--get walls on the active view-----------

FilteredElementCollector collWalls = new FilteredElementCollector(doc, doc.ActiveView.Id);
collWalls.OfClass(typeof(Wall));

foreach (Wall w in collWalls)
{
FilteredElementCollector wallbeam = new FilteredElementCollector(doc, doc.ActiveView.Id);

wallbeam.OfClass(typeof(FamilyInstance));
wallbeam.OfCategory(BuiltInCategory.OST_StructuralFraming);

BoundingBoxXYZ bb = w.get_BoundingBox(doc.ActiveView);
Outline outline = new Outline(bb.Min, bb.Max);
BoundingBoxIntersectsFilter bbfilter =
new BoundingBoxIntersectsFilter(outline);
wallbeam.WherePasses(bbfilter);
foreach (FamilyInstance bem in wallbeam)
{
using (Transaction t = new Transaction(doc, "Join All Walls/beam"))
{
t.Start();
try
{

check = JoinGeometryUtils.AreElementsJoined(doc, w, bem);
if (check == true)
{

}
else
{
JoinGeometryUtils.JoinGeometry(doc, w, bem);
}
}
catch
{
TaskDialog.Show("revit", "cannot joined");
}

t.Commit();
}

}

}

return Result.Succeeded;
}
}
}

I want to join wall and column but there is problem in join. The two element bounding box is joined but not the actual elements are interesect,if I join that element is shows error. I want make code such a way that it check bounding box and also check the actual element is intersect or not. If both condion is statisfy then it join the element.How I do this?

I using the previous posted code.

Please try the following code and tell me if it satisfies your needs:

            UIDocument uidoc = uiApp.ActiveUIDocument;
            Document doc = uidoc.Document;



            //--get walls on the active view-----------
