VB6 PictureBox.line in c# - how?

[chuawenching]

Hi there.

I try to look for this function in c# and cannot find line in pictureBox1!

Any idea what happen to it?

Any idea how to solve it?

Do i really need to use gdi or graphics to do it?

Any help... maybe some sample codes can help me...

Just say the vb6 code is like this

PictureBox1.Line(Paths.GetNode(i).X, Paths.GetNode(i).Z) - (Paths.GetNode(i + 1).X, Paths.GetNode(i + 1).Z), RGB(0, 0, 256)

How will do that exactly in c#?

Path.GetNode() is my own functions of geting x,y,z!

Thanks.

Those as well as shape controls dont exist in .NET anymore. You have to use GDI+ or GDI.

Hmm.. maybe a sample of codes which i can imitate the arguments i use in c#!

I never code in gdi.. maybe some guides on code.. should be cool

thanks for the reply!

You need to create graphics object for your control or use the one that is passed into Paint event or the OnPaint ovverride.
To use the one from Paint event do this:

//in your paint event
e.Graphics.DrawLine(new Pen(Color.Blue),100,100,200,200);
//first you specify the pen used to draw then coordinates

If you want to create the graphics object you do something like this:

Graphics gr = this.CreateGraphics();
gr.DrawLine(new Pen(Color.Blue),100,100,200,200);

Using the paint arguments from the paint event is required to get the maximum performance.

Hmmm...

thanks..

do i code that in Main(), i mean the 2nd code!

But based on:

PictureBox1.Line(Paths.GetNode(i).X, Paths.GetNode(i).Z) - (Paths.GetNode(i + 1).X, Paths.GetNode(i + 1).Z), RGB(0, 0, 256)

--> I need to use drawline and accepts the same argument like picturebox.line

Hmm.. anyway i will give it a try first! See what i can do with gdi power!

Thanks!

Thats essentially what it accepts. First the pen, for which you specify the color, like the RGB argument for the Line Method.
Then the coordinates of the starting point of the line, same as first two in Line and then 2for ending point, again same as Line. Very similar.
Remeber that the second one will only draw it once, if the window needs to repaint you will have to call that method again.

Hmmm.. thanks anyway can you check out my other post on copy bitmap into memory or array...

i am waiting for someone to answer it..

maybe you are the right person..

Thanks.. i am looking into gdi!

Just wondering, when i render 3d in directx, should i use gdi+ or i better use everything on directx 8.1 or 9

what i mean can i integerate gdi into directx?

Thanks.
