如何让vb中的label或text中的部分文字变颜色Vb中Label或者Text只能设置一种文字颜色,无法使部分文字变色
但可以换一种思路,例如
在label中,如果想将部分文字设为其他颜色,可以在label控件上再加一个与这些文字宽度相等的新的label , 平时隐藏,改变文字时,显示 , 并使它上面的文字显示为制定颜色,且调整位置至与原来的文字重叠,就可以达到使部分文字变色的目的了 。
vb.net 如何使文字能渐变颜色,就是颜色慢慢变淡然后在慢慢恢复?也容易vbnet如何文字变色 , 如果是黑白三个颜色加上相同的渐变量vbnet如何文字变色,彩色的是起始颜色的三个分量与终止颜色的对应三个分量的差值vbnet如何文字变色,再除于相同的份数,就得出三原色各自的步进量 。
窗体上放个图片框试试下面代码vbnet如何文字变色:
Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint
Dim startColor As Color = Color.Red
Dim endColor As Color = Color.Green
Dim s As String = "vb.net 如何使文字能渐变颜色,就是颜色慢慢变淡然后在慢慢恢复vbnet如何文字变色?"
Dim Steps As Integer = s.Length \ 2
Dim StepR As Integer = (CInt(endColor.R) - startColor.R) \ Steps
Dim StepG As Integer = (CInt(endColor.G) - startColor.G) \ Steps
Dim StepB As Integer = (CInt(endColor.B) - startColor.B) \ Steps
Dim R As Integer = startColor.R
Dim G As Integer = startColor.G
Dim B As Integer = startColor.B
Dim drawFont As New System.Drawing.Font("Arial", 16)
Dim X As Integer = 50
For i As Integer = 1 To Steps
Dim drawBrush As New SolidBrush(Color.FromArgb(R, G, B))
e.Graphics.DrawString(s.Substring(i - 1, 1), drawFont, drawBrush, X, 50.0)
X += 18
R += StepR
G += StepG
B += StepB
Next
For i As Integer = 1 To Steps
Dim drawBrush As New SolidBrush(Color.FromArgb(R, G, B))
e.Graphics.DrawString(s.Substring(i + Steps - 1, 1), drawFont, drawBrush, X, 50.0)
X += 18
R -= StepR
G -= StepG
B -= StepB
Next
End Sub
