I am creating a application form to view/change a tag from a software called InTouch.
I added the dll as a reference and I would like to use the Read(string tagName
) fct in the IOM.InTouchDataAccess. VS does not see the fct Read when I write InTouchWrapper TagType = new read()
. It only sees InTouchWrapper as I wrote in the code which gives me the error IOM.InTouchDataAccess.InTouchWrapper' does not contain a constructor that takes 0 arguments
I don't understand why is this happening. I am running the InTouch software while coding, maybe there is an access conflict with the software.
MyCode
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using IOM.InTouchDataAccess;
namespace TagBrowser
{
public partial class TagBrowser : Form
{
public TagBrowser()
{
InitializeComponent();
}
private void TagBrowser_Load(object sender, EventArgs e)
{
}
private void TagBox_TextChanged(object sender, EventArgs e)
{
}
private void TypeBox_SelectedIndexChanged(object sender, EventArgs e)
{
InTouchWrapper TagType = new InTouchWrapper();
}
The dll
using System;
using System.Collections.Generic;
using System.Text;
using NDde.Client;
namespace IOM.InTouchDataAccess
{
public class InTouchDdeWrapper : IDisposable
{
private int DDE_TIMEOUT = 60000;
private DdeClient _ddeClient;
public InTouchDdeWrapper()
{
_ddeClient = new DdeClient("View", "Tagname");
}
~InTouchDdeWrapper()
{
Dispose();
}
public void Initialize()
{
_ddeClient.Connect();
}
public string Read(string tagName)
{
return _ddeClient.Request(tagName, DDE_TIMEOUT).Replace("\0", "");
}
I'm putting this here in case somebody else would get the same problem:
Are you sure it's the correct dll you referenced? Try to open the exact referenced dll in a decompiler ( JustDecompile free , Reflector or dotPeek free ) and see if it's the code you expect.
