C# Global Variable

[Kerry Brown]

My statement may have been unclear ... I meant to suggest that you COULD use the same access method as you use for docUI and doc.
ie:

namespace Projects.QuickVisibility_4.CS
{
    public partial class VisibilityForm : System.Windows.Forms.Form
    {
        UIDocument 	docUI;
        Document 	doc;
        Category 	catSections;
        Category 	catGrids;
        Category 	catRefplanes;


        //Check category visibility in the view and populate the checkbox
        public VisibilityForm(ExternalCommandData commandData)
        {
            docUI 	= commandData.Application.ActiveUIDocument;
            doc 	= commandData.Application.ActiveUIDocument.Document;

            RvtView curView      = doc.ActiveView;

            catSections 	= doc.Settings.Categories.get_Item(BuiltInCategory.OST_Sections);
            catGrids 		= doc.Settings.Categories.get_Item(BuiltInCategory.OST_Grids);
            catRefplanes 	= doc.Settings.Categories.get_Item(BuiltInCategory.OST_CLines);

            InitializeComponent();

            bool sectionVis 	= curView.getVisibility(catSections);
            checkBox1.Checked 	= sectionVis == true ? true : false;

            bool gridVis 	= curView.getVisibility(catGrids);
            checkBox2.Checked 	= gridVis == true ? true : false;

            bool refplaneVis 	= curView.getVisibility(catRefplanes);
            checkBox3.Checked 	= refplaneVis == true ? true : false;
        }

        //Get checkbox value and set visibilty in the view
        private void button1_Click(object sender, EventArgs e)
        {
            RvtView curView 	= doc.ActiveView;
            Transaction trans 	= new Transaction(doc);
            trans.Start("Hide or Unhide");

            bool sTorF = checkBox1.Checked == true ? true : false;
            curView.setVisibility(catSections, sTorF);

            bool gTorF = checkBox2.Checked == true ? true : false;
            curView.setVisibility(catGrids, gTorF);

            bool rTorF = checkBox3.Checked == true ? true : false;
            curView.setVisibility(catRefplanes, rTorF);

            trans.Commit();
        }
    }
}

I don't play with Revit so not sure of some of it's pecularities regarding Categories and InitializeComponent();

also;
could this

            bool sTorF = checkBox1.Checked == true ? true : false;
            curView.setVisibility(catSections, sTorF);

become this ;

            curView.setVisibility(catSections, checkBox1.Checked == true ? true : false);

I believe that InitializeComponent() is the standard VS generated code for a winform.

Better (IMO)

            curView.setVisibility(catSections, checkBox1.Checked);

Yes, of course

Kerry / Jeff -

I did not know this about C#, does VB.NET also suffer this shortcoming? I thought that was the point of using a Namespace within an Assembly, to allow for defining of variables, Classes, Properties, etc. without the risk of creating a conflict between Namespaces, no?

It must be contained within a class. You can create static or shared within a project but to accesss it you must use the class like MyClass.MyVariable.

VB will do things under the hood to mimic global varibles. If you place your variable in a module behind the scences VB adds a imports statement to each file in the project since in VB you can import elements(classes, modules, struct, enums, ....) so it seems you are not accessing the variable through the class but MyVariable will be replaced with MClass.MyVarible when compiled.

Jeff, as always, thanks for the clarification.

This is something that I have done before, despite my earlier confusion; recently in the context of a shared function that resided in my "__.vb" Class which contains many sub-functions, so that calls to this function from other Classes resembled core AutoCAD command line calls such as "__.MySubFunc()". *geek*

I am really trying to give C# a go - I've already purchased Andrew Treolsen's "Pro C# 2010 and the .NET 4 Platform" at Kerry's recommendation.
