Stupid error's! (original) (raw)

I am writing a simple text editer but the thing is it wont compile when I add support for opening the file from the command line, the code for it was taken from "Beginning C#" by Karli Watson (Wrox Press). I get three errors!

"formmain.cs(73,5): error CS0117: 'Text_Edit.formMain' does not contain a definition for 'fileName'"
"formmain.cs(492,48): error CS0103: The name 'fileName' does not exist in the class or namespace 'Text_Edit.formMain'"
"formmain.cs(492,5): error CS0029: Cannot implicitly convert type '' to 'System.IDisposable'"

Doesnt having 'string fileName' in the arguments of the function define it? (im used to C++), the third one I don't understand at all!

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.IO;

namespace Text_Edit
{
///

public formMain(string fileName)
{
//
// Required for Windows Form Designer support
//
InitializeComponent();

if (fileName != null)
{
this.fileName = fileName;
OpenFile();
}
}
