(1/1)

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:


--- Code: C# ---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:

 
--- Code: C# ---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:


--- Code: C# ---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:


--- Code: C# ---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:


--- Code: C# ---printDialog1.Document = printDocument1;            if (printDialog1.ShowDialog() == DialogResult.OK)            {                printDocument1.Print();            }
Which gives you:


--- Code: C# ---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:


--- Code: C# ---if (MessageBox.Show("Are you sure you want to quit?", "Exit", MessageBoxButtons.OKCancel) == DialogResult.OK)            {                Application.Exit();            }
Which gives you the following:


--- Code: C# ---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!!!

If you need any specific peices of code explaining, feel free to ask...

To be perfectly honest...I completely forgot about these lol, I have moved on to Delphi programming lately but am more than willing to continue helping people with this :)

Thanks for the good feedback :)
