以下是使用VB(Visual Basic)绘制一个不使用插入图片的生日蛋糕的示例:
1. 打开Visual Studio(或其他VB开发环境),创建一个新的Windows Forms应用程序项目。
2. 在窗体上添加一个PictureBox控件,用于绘制蛋糕。
3. 添加以下代码到窗体的Paint事件处理程序中:
```vb
Private Sub Form1_Paint(sender As Object, e As PaintEventArgs) Handles MyBase.Paint
Dim g As Graphics = e.Graphics
'绘制蛋糕底部
Dim cakeColor As Color = Color.LightPink '蛋糕颜色
Dim cakeWidth As Integer = 200 '蛋糕宽度
Dim cakeHeight As Integer = 300 '蛋糕高度
Dim cakeX As Integer = (Me.ClientSize.Width - cakeWidth) / 2 '蛋糕X坐标
Dim cakeY As Integer = (Me.ClientSize.Height - cakeHeight) / 2 '蛋糕Y坐标
Dim cakeRect As New Rectangle(cakeX, cakeY, cakeWidth, cakeHeight)
g.FillEllipse(New SolidBrush(cakeColor), cakeRect)
'绘制蛋糕顶部
Dim candleColor As Color = Color.Yellow '蜡烛颜色
Dim candleWidth As Integer = 20 '蜡烛宽度
Dim candleHeight As Integer = 50 '蜡烛高度
Dim candleX As Integer = (Me.ClientSize.Width - candleWidth) / 2 '蜡烛X坐标
Dim candleY As Integer = cakeY - candleHeight '蜡烛Y坐标
Dim candleRect As New Rectangle(candleX, candleY, candleWidth, candleHeight)
g.FillRectangle(New SolidBrush(candleColor), candleRect)
'绘制蜡烛火焰
Dim flameColor As Color = Color.OrangeRed '火焰颜色
Dim flameWidth As Integer = 30 '火焰宽度
Dim flameHeight As Integer = 30 '火焰高度
Dim flameX As Integer = (Me.ClientSize.Width - flameWidth) / 2 '火焰X坐标
Dim flameY As Integer = candleY - flameHeight '火焰Y坐标
Dim flameRect As New Rectangle(flameX, flameY, flameWidth, flameHeight)
g.FillEllipse(New SolidBrush(flameColor), flameRect)
End Sub
```
4. 运行程序,即可看到绘制的生日蛋糕效果。
注意:这只是一个简单的示例,实际中你可以根据需求来自定义绘制的蛋糕样式和蜡烛数量。另外,可以通过调整坐标和尺寸来改变蛋糕和蜡烛的位置和大小。
