vb.net亮灭效果的简单介绍

VB.NET关键字上色/高亮问题。

Private Sub RichTextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged

Dim pos = RichTextBox1.SelectionStart

Dim i As String = Regex.Matches(RichTextBox1.Text, "\bDim\b").ToString

RichTextBox1.SelectAll

RichTextBox1.SelectionColor = Color.Black

If Regex.IsMatch(RichTextBox1.Text, "\bDim\b") = True Then

For Each mat As Match In Regex.Matches(RichTextBox1.Text, "\bDim\b")

RichTextBox1.SelectionStart = mat.Index

RichTextBox1.SelectionLength = mat.Length

RichTextBox1.SelectionColor = Color.YellowGreen

Next

End If

RichTextBox1.SelectionStart = pos

RichTextBox1.SelectionLength = 0

End Sub

Q2: [VB.NET]如何用VB在窗体中实现闪烁文字

通过使用VB的Timer控件，程序员可以轻松的在窗体上实现闪烁文字的效果。本文将演示如何为Label控件加上闪烁效果，这种方法同样适用于其它多种控件。以下代码可以完成检验ForeColor属性的任务： Private Sub Timer1_Timer() If Label1.ForeColor = Label1.BackColor Then Label1.ForeColor = vbBlack Else Label1.ForeColor = Label1.BackColor End If End Sub 另外，你也可以让文字采用不同的颜色，比如交替采用红色和绿色： Private Sub Timer1_Timer() If Label1.ForeColor = vbRed Then Label1.ForeColor = vbGreen Else Label1.ForeColor = vbRed End If End Sub 当你停止文字闪烁时，还要确定文字的状态是可见的并且采用了合适的色彩。
