C # applets-menus with history

I wrote a program with the history menu function a few days ago. It was not very well written and too complicated. Yesterday I found a new method, so I wrote it again. The code for dynamically adding a menu is as follows:
[Csharp]
// Menu. ini is a configuration file to store history.
If (File. Exists ("Menu. ini "))
{
StreamReader sr = new StreamReader ("Menu. ini ");
Int I = this. File ToolStripMenuItem. DropDownItems. Count-2;
While (sr. Peek ()> 0)
{
ToolStripMenuItem tlomenu = new ToolStripMenuItem (sr. ReadLine ());
This. File ToolStripMenuItem. DropDownItems. Insert (I, tlomenu );
I ++;
}
Sr. Close ();
}

I also used Visio to draw a simple program process.


The following is the code for the help window:

[Csharp]
/Call API functions
[DllImport ("user32")]
Private static extern long FlashWindow (IntPtr handle, bool bInvert );
 
Private void btnClose_Click (object sender, EventArgs e)
{
This. Close ();
}
 
Private void timereffectick (object sender, EventArgs e)
{
FlashWindow (this. Handle, true );
}

Select the font window code:

[Csharp]
Public FrmFont (Frm frm)
{
InitializeComponent ();
MianFrm = frm;
}
 
Frm mianFrm = new Frm ();
// Define the intermediate variable.
Public Font newFont;
Public bool getBlod;
Public bool getItalic;
 

// Add the font and size to the program.
Private void FrmFont_Load (object sender, EventArgs e)
{
InstalledFontCollection iof = new InstalledFontCollection ();
Foreach (FontFamily font in iof. Families)
{
CboFont. Items. Add (font. Name );
}
For (int I = 1; I <100; I ++)
CboSize. Items. Add (I );
}
 
Public void UpdateFrmMain ()
{
If (cboFont. SelectedIndex> 0)
{
Try
{
NewFont = new Font (cboFont. SelectedItem. ToString (), newFont. Size );
}
Catch
{}
}
If (cboSize. SelectedIndex> 0)
{
NewFont = new Font (newFont. FontFamily, float. Parse (cboSize. SelectedItem. ToString ()));
}
MianFrm. rtbNotePad. Font = newFont;
}
// Font selection changes
Private void cboFont_SelectedIndexChanged (object sender, EventArgs e)
{
UpdateFrmMain ();
}
// Font size drop-down box change
Private void cboSize_SelectedIndexChanged (object sender, EventArgs e)
{
UpdateFrmMain ();
}
 
The program runs as follows:

The main form code is as follows:
[Csharp]
// Define variables
StreamWriter str = null;
String strTemp;
String path = System. IO. Directory. GetCurrentDirectory ();
 
Private void help ToolStripMenuItem_Click (object sender, EventArgs e)
{
// Call the help form
FrmHelp help = new FrmHelp ();
Help. ShowDialog ();
}

// Open the file
Private void open ToolStripMenuItem_Click (object sender, EventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog ();
If (ofd. ShowDialog () = DialogResult. OK)
{
This. rtbNotePad. Text + = ofd. FileName;
This. rtbNotePad. LoadFile (ofd. FileName, RichTextBoxStreamType. PlainText );
String destination FileName = ofd. FileName. Substring (ofd. FileName. LastIndexOf ("\") + 1 );
This. Text = optional filename;
 
ToolStripMenuItem tlomenu = new ToolStripMenuItem (ofd. FileName );
Int I = this. File ToolStripMenuItem. DropDownItems. Count-2;
This. File ToolStripMenuItem. DropDownItems. Insert (I, tlomenu );
Tlomenu. Click + = new EventHandler (ToolStripMenuItem_Click );
}
}
 
Private void create ToolStripMenuItem_Click (object sender, EventArgs e)

{

Str. Write (strTemp );
}
}

Catch
{};

}
 
Private void Frm_Load (object sender, EventArgs e)

{

String temp;
