Based on a question I asked earlier, I did some work an managed to draw a line on my form using DirectX. This is the code if anyone is interested:
Now based on this, whenever I wrote Me.Handle instead of GetHandle() on the following line:
It seemed to work and draw the line on my own form.
But, as you might know I want to draw it on a another form and therefore I aquired that handle. Anyone got any ideas why it doesn't work?
Again many thanks in advance.
Code:
Imports Microsoft.DirectX
Imports Microsoft.DirectX.Direct3D
Public Class Form1
Dim device As Direct3D.Device
Dim buffer As VertexBuffer
Private Function GetHandle() As IntPtr
Dim p As Process = Process.GetProcessesByName("SA RS Tools")(0)
Return p.Handle
End Function
Private Sub initilizdx()
Dim present As New PresentParameters
present.BackBufferCount = 1
present.BackBufferFormat = Manager.Adapters(0).CurrentDisplayMode.Format
present.BackBufferHeight = Me.Height
present.BackBufferWidth = Me.Width
present.Windowed = True
present.SwapEffect = SwapEffect.Discard
device = New Device(0, DeviceType.Hardware, GetHandle(), CreateFlags.SoftwareVertexProcessing, present)
device.RenderState.CullMode = Cull.None
End Sub
Private Sub creat_vertxbuffer()
buffer = New VertexBuffer(GetType(CustomVertex.TransformedColored), 2, device, Usage.None, CustomVertex.TransformedColored.Format, Pool.Managed)
Dim ver(1) As CustomVertex.TransformedColored
ver(0) = New CustomVertex.TransformedColored(10, 50, 0, 1, Color.Red.ToArgb)
ver(1) = New CustomVertex.TransformedColored(100, 50, 0, 1, Color.Green.ToArgb)
buffer.SetData(ver, 0, LockFlags.None)
End Sub
Private Sub draw_me()
device.Clear(ClearFlags.Target, Color.Transparent, 0, 0)
device.BeginScene()
device.VertexFormat = CustomVertex.TransformedColored.Format
device.SetStreamSource(0, buffer, 0)
device.DrawPrimitives(PrimitiveType.LineStrip, 0, 1)
device.EndScene()
device.Present()
