Hello,
I can't get the currently path of a dll class library, which is loaded as an ActiveX in a ASP.NET web site.
I have tried several commands, but no success. For example, I tried to get current path in variable _path:

namespace WebScanControl {

    [ApplicationControl(Width=640,Height=480)]
    public sealed partial class ScanControl:ApplicationControl {

        public ScanControl() {
            InitializeComponent();
        }

        protected override void Construct(ReadOnlyCollection<object> args) {
            try {

                string _path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);


            } catch(Exception ex) {
                MessageBox.Show(string.Format("{1}{0}{2}", Environment.NewLine, ex.Message, ex.StackTrace), ex.GetType().Name, MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
            base.Construct(args);
        }

     }
}

Open in new window

However, variable _path gets:

C:\Users\miyahira\AppDataLocalTemp\3f3574554-2ef8-e8r9-9c8b-e40561d03bb

Which is not its path.

As you see, this class library is an ApplicationControl. Is that tht reason why it's not possible to get its current path?

It's because you are using GetExecutingAssembly, which returns the executing assembly.  If you want to get the location of the DLL for the ApplicationControl type, you want to use the GetAssembly method, i.e. -
using System;
using System.Drawing;
using System.Reflection;
using System.Windows.Forms;

namespace EE_Q28606618
{
	class Program
	{
		static TextBox textBox1 = new TextBox();
		static Color color1 = Color.AliceBlue;
		static SomeObject someObject1 = new SomeObject();

		static void Main(string[] args)
		{
			Console.WriteLine("Location of TextBox: {0}", Assembly.GetAssembly(textBox1.GetType()).Location);
			Console.WriteLine("Location of Color: {0}", Assembly.GetAssembly(color1.GetType()).Location);
			Console.WriteLine("Location of SomeObject: {0}", Assembly.GetAssembly(someObject1.GetType()).Location);
			Console.ReadLine();
		}
	}

	class SomeObject
	{
		public SomeObject() { ;}

		public override string ToString() { return "I am some object"; }
	}
}

Open in new window

Which produces the following output -Capture.JPG-saige-

Sorry, I didn't explain myself clearly. What I am looking is the path where my created dll is loaded, I'm talking about  WebScanControl.dll.

Please use CodeBase property as follows:
string _path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().CodeBase);
