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");
}
