Answer 2

请确保commonDialog控件已拖放到form上，具体步骤为：在vb的project菜单下，打开components子菜单，在弹出窗口中的controls标签页下，找到Microsoft
Common
Dialog
?.0(SP?)打上勾后确定，确定之后在控件选择那个栏位表会出现一个新加入的图标，鼠标移上去会出现CommonDialog字样，将它点击拖入你建立的窗体上，再尝试运行

Answer 3

没有在窗体添加
CommonDialog
控件
Ctrl+T，选择
microsoft
common
dialog..
再在工具箱中将其拖到窗体即可

CSDN的下载 需要先注册会员 我下载过 基本实现记事本的需求

Answer 5

以前做过.并不难实现,VB有个控件rich textbox,记事本的基本功能都能用它实现
