How to Create a Notepad application in Visual Studio
Now, we will learn how to create a Notepad application in Visual Studio easily and quickly. In this article, we are going to use Menustrip control, adding menu items to Menustrip control, dialog controls, etc.
Please follow below steps to create a Notepad application.
Step 1: Take a new Windows Form and add a 'Menu Strip' control to it.
Step 2: For Form set its Text as "Untitled - My Notepad"
Step 3: On the Menu strip add 4 Menus
· File
· Edit
· Format
· Help
Step 4: Under 'File' Menu add the following Menu items
· New
· Open
· Save
· Save As
· Close
Step 5: Under the 'Edit' Menu add the following items
· Cut
· Copy
· Paste
Step 6: Under 'Format' Menu add the following items
· Word Warp (Checked)
· Color
Step 7: Under 'Help' Menu add the Menu item
· Calculator
· About My Notepad
Step 8: Place a 'RichTextBox' control and set its 'Dock' Property as 'Fill' and also change the name of it as "rtbData".
Step 9: Add a 'OpenFileDialog', 'SaveFileDialog', 'ColorDialog', and 'FontDialog' to the form.
Step 10: Now write the below code.
Using System.Diagnostics;
Declarations:
bool close = true;
private void SaveNewFile()
{
if(rtbData.Text.Trim().Length > 0)
{
DialogResult dr=MessageBox.Show("The text in the Untitled file has changed.\
n\Do you want to save the Changes?", "My Notepad",
MessageBoxButtons.YesNoCancel,MessageBoxIcon.Information);
if(dr==DialogResult.Yes)
{
DialogResult d=SaveFileDialog1.ShowDialog();
if(d!=DialogResult.Cancel)
{
string fpath=SaveFileDialog1.FileName;
rtbData.SaveFile(fpath,RichTextBoxStreamType.PlainText);
rtbData.Clear();
}
}
else if(dr==Dialog.Result.No)
rtbData.Clear();
else if(dr==DialogResult.Cancel)
Close=false;
}
}
Under 'New' Menu item:
SaveNewFile();
Under 'Open' Menu Item:
SaveNewFile();
OpenFileDialog1.ShowDialog();
string fpath=OpenFileDialog1.FileName;
rtbData.LoadFile(fpath,RichTextBoxStreamType.PlainText);
this.Text=fpath;
private void SaveFile()
{
SaveFileDialog1.ShowDialog();
string fpath=SaveFileDialog1.FileName;
rtbData.SaveFile(fpath,RichTextBoxStreamType.PlainText);
this.Text=fpath;
}
Under 'Save' Menu Item:
if(this.Text=="Untitled-MyNotepad")
SaveFile();
else
rtbData.SaveFile(this.Text,RichTextBoxStreamType.PlainText);
Under 'SaveAs' Menu Item:
SaveFile();
Under 'Close' Menu Item:
SaveNewFile();
if(Close==true)
this.Close();
close=true;
Under 'Cut' Menu Item:
rtbData.Cut();
Under 'Copy' Menu Item:
rtbData.Copy();
Under 'Paste' Menu Item:
rtbData.Paste();
Under 'WordWrap' Menu Item:
if(WordWrapToolStringMenuItem.Checked==true)
{
WordWrapToolStringMenuItem.Checked==false;
rtbData.WordWrap=false;
}
else
{
WordWrapToolStringMenuItem.Checked=true;
rtbData.WordWrap=true;
}
Under 'Font' Menu Item:
FontDialog1.ShowDialog();
rtbData.Font=fontDialog1.Font;
Under 'Color' Menu Item:
colorDialog1.ShowDialog();
rtbData.ForeColor=colorDialog1.color;
Under 'Calculator' Menu Item:
Process. Start ("calc.exe");
Now, open the Add New Item window and add a New Item choosing the option as "About Box" which will add a New Form as "AboutBox1.cs". By default the Form designed to be used as an About Box so make required changes and then write the below code under "About MyNotepad" Menu Item:
AboutBox1 f=new AboutBox1 ();
f.ShowDialog ();
Now we done with sample Notepad application which is same as Notepad application there in Windows Operating System. We can easily develop this kind of applications with ease and quick with Visual Studio.
Happy Learning….!!!!!
