Tutorial: Visual C# For Beginners - Part 3 (With Pretty Pictures!!!)

Welcome To Part 3:

I'm sure that if you have completed Parts 1 & 2 then you are keen to continue with your project, so lets get cracking with that File Menu!

For this, you are going to need to add the following items:

openFileDialog
saveFileDialog
printDialog
printDocument

To add these to your project, click and drag them onto the bottom menu bar

Now you have added them all you will have something that looks like this:

Brilliant!

Now...Remembering what you learned in Part 2 you need to go ahead and click the "File" button and then double click the "Open" button

Add:

Formatted for C# with the GeSHI Syntax Highlighter [copy or print]
string OFile = "";
 
            openFileDialog1.InitialDirectory = "C:";
            openFileDialog1.Title = "Open a Text File";
            openFileDialog1.FileName = "";
            openFileDialog1.Filter = "Text Files|*.txt|Word Documents|*.doc";
            if (openFileDialog1.ShowDialog() != DialogResult.Cancel)
            {
                OFile = openFileDialog1.FileName;
                richTextBox1.LoadFile(OFile, RichTextBoxStreamType.PlainText);
            }

Which should give you:

Formatted for C# with the GeSHI Syntax Highlighter [copy or print]
private void openToolStripMenuItem_Click(object sender, EventArgs e)
        {
            string OFile = "";
 
            openFileDialog1.InitialDirectory = "C:";
            openFileDialog1.Title = "Open a Text File";
            openFileDialog1.FileName = "";
            openFileDialog1.Filter = "Text Files|*.txt|Word Documents|*.doc";
            if (openFileDialog1.ShowDialog() != DialogResult.Cancel)
            {
                OFile = openFileDialog1.FileName;
                richTextBox1.LoadFile(OFile, RichTextBoxStreamType.PlainText);
            }
        }

Now you want to go back and double click "Save"

Add:

Formatted for C# with the GeSHI Syntax Highlighter [copy or print]
string SFile = "";
 
            openFileDialog1.InitialDirectory = "C:";
            openFileDialog1.Title = "Save Your Notes!";
            openFileDialog1.FileName = "";
            openFileDialog1.Filter = "Text Files|*.txt|Word Documents|*.doc";
            if (openFileDialog1.ShowDialog() != DialogResult.Cancel)
            {
                SFile = saveFileDialog1.FileName;
                richTextBox1.SaveFile(SFile, RichTextBoxStreamType.PlainText);
            }

Which gives you:

Formatted for C# with the GeSHI Syntax Highlighter [copy or print]
private void saveToolStripMenuItem_Click(object sender, EventArgs e)
        {
            string SFile = "";
 
            openFileDialog1.InitialDirectory = "C:";
            openFileDialog1.Title = "Save Your Notes!";
            openFileDialog1.FileName = "";
            openFileDialog1.Filter = "Text Files|*.txt|Word Documents|*.doc";
            if (openFileDialog1.ShowDialog() != DialogResult.Cancel)
            {
                SFile = saveFileDialog1.FileName;
                richTextBox1.SaveFile(SFile, RichTextBoxStreamType.PlainText);
            }
        }

Now for the "Print" option:

Add:

Formatted for C# with the GeSHI Syntax Highlighter [copy or print]
printDialog1.Document = printDocument1;
            if (printDialog1.ShowDialog() == DialogResult.OK)
            {
                printDocument1.Print();
            }

Which gives you:

Formatted for C# with the GeSHI Syntax Highlighter [copy or print]
       private void printToolStripMenuItem_Click(object sender, EventArgs e)
        {
            printDialog1.Document = printDocument1;
            if (printDialog1.ShowDialog() == DialogResult.OK)
            {
                printDocument1.Print();
            }
        }

Now we are going to extend our "Exit" button. Go to the designer, click "File", double click "Exit" and delete 'Application.Exit();'

Add the following code in its place:

Formatted for C# with the GeSHI Syntax Highlighter [copy or print]
           if (MessageBox.Show("Are you sure you want to quit?", "Exit", MessageBoxButtons.OKCancel) == DialogResult.OK)
            {
                Application.Exit();
            }

Which gives you the following:

Formatted for C# with the GeSHI Syntax Highlighter [copy or print]
       private void exitToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (MessageBox.Show("Are you sure you want to quit?", "Exit", MessageBoxButtons.OKCancel) == DialogResult.OK)
            {
                Application.Exit();
            }
        }

Awesome!!!!!

Save your project and go play with it! You can even run a print from it if you own a printer!!!

Thats all for this tutorial.

In the next we will add code for "Save As" and "Print Preview".

We will also make a start with our Tools Menu! Even adding things like Fonts and Colours!!!
