Introduction

The purpose of the article is to illustrate the use of colordialog, fontdialog, linklabel and helpprovider. This is a simple demo of how they work.

This article illustrates one of my first C# code. I wanted to use MDI control and try out the linklabel control and the helpprovider control.

I had problems creating an About dialog box and hence I coded an application that uses system dialog to change the font and color of a text and the help provider opens the help HTML file, which displays the help message.

The name of the class is MainDlg, which comprises of a Label, colordialog, fontdialog and a helpprovider.

private void menuItem2_Click(object sender, System.EventArgs e)
{
    fontDialog1.ShowDialog();
    label2.Font = fontDialog1.Font;
}

private void menuItem3_Click(object sender, System.EventArgs e)
{
    colorDialog1.ShowDialog();
    label2.ForeColor = colorDialog1.Color;
}

private void menuItem6_Click(object sender, System.EventArgs e)
{
    AboutDlg ne = new AboutDlg();
    ne.ShowDialog();
}

private void menuItem9_Click(object sender, System.EventArgs e)
{
    Help.ShowHelp(new MainDlg() ,"help.htm");
}

There is another class which is an inherited class called AboutDlg, this comprises of a linklabel , which carries an email ID.

By using the following code, the mail recipient is invoked.

private void linkLabel1_LinkClicked_1(object sender, 
     System.Windows.Forms.LinkLabelLinkClickedEventArgs e)
{
    linkLabel1.LinkVisited = true;
    System.Diagnostics.Process.Start("mailto:ragava@fastmail.ca");
}
