VB中的Rich TextBox控件中如何使第三个字显示红色

Answer 1

简单的：
Private Sub Command1_Click()
RichTextBox1.SelStart = 2
RichTextBox1.SelLength = 1
RichTextBox1.SelColor = vbRed
End Sub

更人性化的：
Private Sub Command1_Click()
Dim MySelStart As Integer, MySelLength As Integer
'记录RichTextBox的光标位置和选定长度
MySelStart = RichTextBox1.SelStart
MySelLength = RichTextBox1.SelLength
'选定第三个字符，并且颜色设为红色
RichTextBox1.SelStart = 2
RichTextBox1.SelLength = 1
RichTextBox1.SelColor = vbRed
'恢复之前的光标位置和选定长度
RichTextBox1.SelStart = MySelStart
RichTextBox1.SelLength = MySelLength
End Sub
