闲来没事写个记事本玩玩！！！
阅读: 614 评论: 7 作者: 苏飞 发表于 2010-03-03 18:14 原文链接
这两天工作压力大，还好今天见着太阳了，这会儿没事写了个记事本，功能单一，适合练手，可能对新手会有所帮助，贴上来看看吧，
说到实现 记事本，我们应该选择什么样的控件呢，TextBox，还是RichTextBox ，TextBox的功能单一，对文字和颜色的支持基本上能用，但是说到图片就不行了
RichTextBox 在这一点上比它做的好，不过在版面的格式 上还有点不好，TextBox就不用说了基本上无法保存
如果是一般的功能使用的话，用RichTextBox足以，但是如果要实现更复杂一点功能 的话就不够用了，在这里我提一点点的思路，改写一下RichTextBox吧，这个方法有很多，网上也有不少，我是这样来实现的先到网上找一个写的差不多的，因为是写着玩，没有必要自己下功能写一个完整的，找个格式 和功能 差不多的，改一下就OK，这是我的源码，大家分享一下

/// This class adds the following functionality to RichTextBox:
///
/// 1 . Allows plain text to be inserted or appended programmatically to RTF
/// content.
/// 2 . Allows the font, text color, and highlight color of plain text to be
/// specified when inserting or appending text as RTF.
/// 3 . Allows images to be inserted programmatically, or with interaction from
/// the user .
/// </ summary >
/// < remarks >
/// Many solutions to the problem of programmatically inserting images
/// into a RichTextBox use the clipboard or hard code the RTF for
/// the image in the program. This class is an attempt to make the process of
/// inserting images at runtime more flexible without the overhead of maintaining

有了它我们的功能实现起来就方便太多了，第一步先看看实现 的效果吧
界面就是这个样子的
功能 不算多，就是对文件的格式 大小颜色，图片的位置还有文件的保存，打印等文件的处理
主窗下面有一个子窗体是来实现文字编辑的，主窗体主要是实现子窗体的版式，这样可以实现 多窗口化工作，比平常的notepad高了一级
菜单只要插入一个标准项目就可以了，还有就是工具也是同样的，SM自带的就够用了，
一个一个的来说吧，
先来说一下，字体是处理吧，
MS做的太多了， 只要下面几行就行了
代码
FontDialog fontDialog
=
new FontDialog();
// 当前字体的颜色
fontDialog.Color = rtMain.ForeColor;
fontDialog.AllowScriptChange = true;
// 如果要同时指定颜色的话可以在这里设置
// fontDialog.ShowColor = true;
if (fontDialog.ShowDialog() != DialogResult.Cancel)
{
// 将当前选定的文字改变字体
rtMain.SelectionFont = fontDialog.Font;
// 如果要同时指定颜色的话可以在这里取得
// rtMain.SelectionColor = fontDialog.Color;
}
rtMain.Focus();
// 当前字体的颜色
fontDialog.Color = rtMain.ForeColor;
fontDialog.AllowScriptChange = true;
// 如果要同时指定颜色的话可以在这里设置
// fontDialog.ShowColor = true;
if (fontDialog.ShowDialog() != DialogResult.Cancel)
{
// 将当前选定的文字改变字体
rtMain.SelectionFont = fontDialog.Font;
// 如果要同时指定颜色的话可以在这里取得
// rtMain.SelectionColor = fontDialog.Color;
}
rtMain.Focus();
rtMain 就是我前面所说的ZYBTextBox控件的名称
有了这个字体的实现下面的基本如一，下面来看颜色
代码
ColorDialog colorDialog
=
new ColorDialog();
// 是否开启自定义颜色
colorDialog.AllowFullOpen = true;
colorDialog.FullOpen = true;
// 是不有帮助
colorDialog.ShowHelp = true;
// 初始化当前文本框中的字体颜色，当用户在ColorDialog对话框中点击"取消"按钮恢复原来的值
colorDialog.Color = Color.Black;
if (colorDialog.ShowDialog() != DialogResult.Cancel)
{
// 将当前选定的文字改变颜色
rtMain.SelectionColor = colorDialog.Color;
}
rtMain.Focus();
// 是否开启自定义颜色
colorDialog.AllowFullOpen = true;
colorDialog.FullOpen = true;
// 是不有帮助
colorDialog.ShowHelp = true;
// 初始化当前文本框中的字体颜色，当用户在ColorDialog对话框中点击"取消"按钮恢复原来的值
colorDialog.Color = Color.Black;
if (colorDialog.ShowDialog() != DialogResult.Cancel)
{
// 将当前选定的文字改变颜色
rtMain.SelectionColor = colorDialog.Color;
}
rtMain.Focus();
还有图片
图片的实现有点不同，不过基本上一样
也是先得到文件，然后用 Bitmap img = new Bitmap(fName); 加一下就OK了
然后添加应该 rtMain.InsertImage(img);
下面是实现的代码
代码
OpenFileDialog openFileDialog
=
new OpenFileDialog();
// 初始目录
// openFileDialog.InitialDirectory = "d:\\";
// 图片格式
openFileDialog.Filter = "位图文件 |* .bmp | gif文件 |* .gif | TIFF文件 |* .tif | jpg文件 |* .jpg | 所有文件 |* . * ";
// 还原当前目录
openFileDialog.RestoreDirectory = true;
// 默认的文件格式
openFileDialog.FilterIndex = 1 ;
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
try
{
string fName = openFileDialog.FileName;
// 加载图片
Bitmap img = new Bitmap(fName);
// 添加到ZYBTextBox中
rtMain.InsertImage(img);
}
catch (System.IO.FileNotFoundException)
{
MessageBox.Show("没有找到文件！", "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
rtMain.Focus();
// 初始目录
// openFileDialog.InitialDirectory = "d:\\";
// 图片格式
openFileDialog.Filter = "位图文件 |* .bmp | gif文件 |* .gif | TIFF文件 |* .tif | jpg文件 |* .jpg | 所有文件 |* . * ";
// 还原当前目录
openFileDialog.RestoreDirectory = true;
// 默认的文件格式
openFileDialog.FilterIndex = 1 ;
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
try
{
string fName = openFileDialog.FileName;
// 加载图片
Bitmap img = new Bitmap(fName);
// 添加到ZYBTextBox中
rtMain.InsertImage(img);
}
catch (System.IO.FileNotFoundException)
{
MessageBox.Show("没有找到文件！", "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
rtMain.Focus();
字体加粗的实现
代码
//
处理粗体显示
System.Drawing.Font oldFont = rtMain.SelectionFont;
System.Drawing.Font newFont;
if (oldFont.Bold)
newFont = new Font(oldFont, oldFont.Style & ~ FontStyle.Bold);
else
newFont = new Font(oldFont, oldFont.Style | FontStyle.Bold);
rtMain.SelectionFont = newFont;
rtMain.Focus();
System.Drawing.Font oldFont = rtMain.SelectionFont;
System.Drawing.Font newFont;
if (oldFont.Bold)
newFont = new Font(oldFont, oldFont.Style & ~ FontStyle.Bold);
else
newFont = new Font(oldFont, oldFont.Style | FontStyle.Bold);
rtMain.SelectionFont = newFont;
rtMain.Focus();
当然像斜体，下划线的实现方法就基本和加粗是一样的了
代码
//
处理斜体显示
public void ttsbItalic_Click(object sender, EventArgs e)
{
// 处理斜体显示
System.Drawing.Font oldFont = rtMain.SelectionFont;
System.Drawing.Font newFont;
if (oldFont.Italic)
newFont = new Font(oldFont, oldFont.Style & ~ FontStyle.Italic);
else
newFont = new Font(oldFont, oldFont.Style | FontStyle.Italic);
rtMain.SelectionFont = newFont;
rtMain.Focus();
}
// 处理下划线显示
public void ttsbUnderLine_Click(object sender, EventArgs e)
{
// 处理下划线显示
System.Drawing.Font oldFont = rtMain.SelectionFont; ;
System.Drawing.Font newFont;
if (oldFont.Underline)
newFont = new Font(oldFont,oldFont.Style &~ FontStyle.Underline);
else
newFont = new Font(oldFont,oldFont.Style | FontStyle.Underline);
rtMain.SelectionFont = newFont;
rtMain.Focus();
}
public void ttsbItalic_Click(object sender, EventArgs e)
{
// 处理斜体显示
System.Drawing.Font oldFont = rtMain.SelectionFont;
System.Drawing.Font newFont;
if (oldFont.Italic)
newFont = new Font(oldFont, oldFont.Style & ~ FontStyle.Italic);
else
newFont = new Font(oldFont, oldFont.Style | FontStyle.Italic);
rtMain.SelectionFont = newFont;
rtMain.Focus();
}
// 处理下划线显示
public void ttsbUnderLine_Click(object sender, EventArgs e)
{
// 处理下划线显示
System.Drawing.Font oldFont = rtMain.SelectionFont; ;
System.Drawing.Font newFont;
if (oldFont.Underline)
newFont = new Font(oldFont,oldFont.Style &~ FontStyle.Underline);
else
newFont = new Font(oldFont,oldFont.Style | FontStyle.Underline);
rtMain.SelectionFont = newFont;
rtMain.Focus();
}
对的打印这一块，我是直接使用的控件，呵呵 最后我会把源码放进来大家自己看吧，这里就不在多说了，
下面说一下存储方面的，
打开文件，实现很简单可以说跟上面所说的字体啊，图片啊， 都 差不多，
代码
OpenFileDialog openFileDialog = new OpenFileDialog();
// 初始目录设定
openFileDialog.InitialDirectory = "d:\\";
// 指定打开文件的格式
openFileDialog.Filter = "文本文件 |* .txt | RTF文件 |* .rtf | 所有文件 |* . * ";
// 还原当前的目录
openFileDialog.RestoreDirectory = true;
openFileDialog.FilterIndex = 2 ;
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
try
{
// 文件名
string fName = openFileDialog.FileName;
// 加载文件到编辑器里
rtMain.LoadFile(fName);
printDocument.DocumentName = Path.GetFileName(fName);
strFileName = fName;
// 取一个含有扩展名的文件名当做标题
this. Text = Path.GetFileNameWithoutExtension(fName) + " -- 记事本";
}
catch (System.IO.FileNotFoundException)
{
MessageBox.Show("没有找到文件！", "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
rtMain.Focus();
直接 把代码复制就行了，
自然还得有保存，
保存就更文件了，呵呵
代码
SaveFileDialog saveFileDialog
=
new SaveFileDialog();
// 指定打开文件的格式
saveFileDialog.Filter = "文本文件 |* .txt | RTF文件 |* .rtf | 所有文件 |* . * ";
saveFileDialog.FilterIndex = 2 ;
// 还原当前目录
saveFileDialog.RestoreDirectory = true;
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
try
{
// 要保存的位置
string strName = saveFileDialog.FileName;
switch (Path.GetExtension(strName).ToLower())
{
case ".txt":
rtMain.SaveFile(strName, RichTextBoxStreamType.PlainText);
break ;
case ".rtf":
rtMain.SaveFile(strName, RichTextBoxStreamType.RichText);
break ;
default :
rtMain.SaveFile(strName);
break ;
}
}
catch (System.Exception err)
{
MessageBox.Show(err.Message);
}
}
rtMain.Focus();
// 指定打开文件的格式
saveFileDialog.Filter = "文本文件 |* .txt | RTF文件 |* .rtf | 所有文件 |* . * ";
saveFileDialog.FilterIndex = 2 ;
// 还原当前目录
saveFileDialog.RestoreDirectory = true;
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
try
{
// 要保存的位置
string strName = saveFileDialog.FileName;
switch (Path.GetExtension(strName).ToLower())
{
case ".txt":
rtMain.SaveFile(strName, RichTextBoxStreamType.PlainText);
break ;
case ".rtf":
rtMain.SaveFile(strName, RichTextBoxStreamType.RichText);
break ;
default :
rtMain.SaveFile(strName);
break ;
}
}
catch (System.Exception err)
{
MessageBox.Show(err.Message);
}
}
rtMain.Focus();
然后在关闭这个窗体 的时候 加上个判断，功能就基本实现 了
if
(MessageBox.Show("要保存现有文件吗", "提示对话框", MessageBoxButtons.YesNo, MessageBoxIcon.Question)
== DialogResult.Yes)
保存SToolStripMenuItem_Click(sender, e);
== DialogResult.Yes)
保存SToolStripMenuItem_Click(sender, e);
对于基本的复制，粘贴，等操作其实只要调用 一下文件就行了，
就不在多贴代码了下了，下面把所有实现 的代码贴上来，有兴趣的朋友找一下吧，
也希望能多提建议，能帮上忙的和很高兴，帮不上的也希望能提提建议，呵呵
