C#开发DirectX D3D 窗体一最下化就出异常,望DirectX高手帮助!!! 郁闷中...

Question

不会不过帮你顶

Answer 1

谢谢各位帮忙,不过我跟踪了.应为是while循环,我跟不了.错误是D3D内部错误while (MyForm.Created)
{
if (MyForm.Ini(MyForm.hScrollBar1))
{
MyForm.DrawScale();
MyForm.DrawWaveForm(MyForm.hScrollBar1.Value,
                    MyForm.TotalPointNum,
                    MyForm.PointNumPerPage,
            MyForm.Range,
                    MyForm.AcquireFrequency,
    MyForm.DataVector);

    Application.DoEvents();
}
}
:(

我测试发现如注释该函数则窗口最小化则无异常public bool InitializeGraphics()
{
try
{
// Now  setup our D3D stuff
PresentParameters presentParams = new PresentParameters();
presentParams.Windowed=true;
presentParams.SwapEffect = SwapEffect.Discard;
DeviceForScale = new Device(0, DeviceType.Reference, this, 
    CreateFlags.SoftwareVertexProcessing,                                             presentParams);
                
//>>>
                PresentParameters presentParams2 = new PresentParameters();
presentParams2.Windowed=true;
presentParams2.SwapEffect = SwapEffect.Discard;
DeviceForWaveForm = new Device(0, DeviceType.Hardware, panelShow,           CreateFlags.SoftwareVertexProcessing,                                                presentParams2); return true;
}
catch (DirectXException)
{ 
return false; 
}
}
