我正在Windows Mobile智能设备应用程序上绘制一个图片框。该图表运行良好,但之后立即消失。如何使照片保持在Picturebox上?
我用行:
this.Invoke(new EventHandler(picture2_show));
和我的画法:
private void picture2_show(object sender, EventArgs e)
{
using (Graphics objGraphics = this.pictureBox2.CreateGraphics())
{
Pen redpen = new Pen(Color.Red, 1);
int picBoxWidth = pictureBox2.Size.Width;
int picBoxHeight = pictureBox2.Size.Height;
int halfWidth = pictureBox2.Size.Width/2;
int halfHeight = pictureBox2.Size.Height/2;
Graphics objGraphic = this.pictureBox2.CreateGraphics();
objGraphic.DrawLine(redpen, 0, 0, 0, picBoxHeight);
objGraphic.DrawLine(redpen, 0, picBoxHeight - 1, picBoxWidth, picBoxHeight - 1);
//Rectangle first = new Rectangle(0, halfHeight, picBoxWidth, halfHeight);
Pen bpen = new Pen(Color.LawnGreen, 3);
for (int i = 0; i < array.Length - 1; i++)
{
objGraphic.DrawLine(
bpen,
pictureBox2.Size.Width * i/array.Length,
pictureBox2.Size.Height - array[i],
pictureBox2.Size.Width * (i + 1)/array.Length,
pictureBox2.Size.Height - array[i + 1]);
}
}
}
PictureBox的停留,但如何使图不会消失?

不客气。你应该通过点击空心支票来接受这个答案。 – SLaks 2011-04-22 17:22:50
