dynamic ListBox Created.

[jahyun100]

I created a combo box using ActiveX.
I received an "unknown name" error when trying to check the selected item

        public void Macro_Init_CombBox()

        {

            try

            {

                //Get the zenon Element

                zenOn.IElement zElementActivX = this.Project.DynPictures().Item("top").Elements().Item("ActiveX_1");

                //Set the zenon AktiveX Element as ComboBox Control

                 Microsoft.Vbe.Interop.Forms.ComboBox combo = zElementActivX.AktiveX() as Microsoft.Vbe.Interop.Forms.ComboBox;

                object defaultParameter = null;

                //Fill the ComboBox with Items

                int y = 1970;   

                string a = DateTime.Now.ToString("yyyy");

                int lastYear = Convert.ToInt32(a);

                object k = 1970;

                int asdf = 0;

                for (y = 1970; y <= lastYear; y++)

                {

                    k = y;

                    defaultParameter = asdf;

                    combo.AddItem(ref k, ref defaultParameter);

                    asdf++;

                }

                

            }

            catch (Exception ex)

            {

                System.Diagnostics.Debug.Print("ERROR Macro_Init(): "

                + ex.Message + " " + ex.Source);

            }

        }

        public void Macro_seletedItems()

        {

           

            try

            {

                 zenOn.IElement zElementActivX = this.Project.DynPictures().Item("top").Elements().Item("ActiveX_1");

                Microsoft.Vbe.Interop.Forms.ComboBox combo = zElementActivX.AktiveX() as Microsoft.Vbe.Interop.Forms.ComboBox;

            

                string temp = combo.SelText;  //error

            }

            catch (Exception ex)

            {

                System.Diagnostics.Debug.Print("ERROR Macro_Init(): "

                + ex.Message + " " + ex.Source);

            }

        }

I changed the way WPF.
But controls are invisible

I do not know how to put an item in a Combobox in C #.

Hi!

Do you really need to make the listbox/combobox in code instead of the one provided as a dynamic element in zenon?
You can dynamically fill it with text/values by using a string-variable.
