System.Runtime.InteropServices.COMException（0x88980406）

我们有一个连接到显微镜的WPF应用程序。 有一种情况，在应用程序中我们可以切换显微镜的物镜，当我们这样做时，有一个硬件调用，告诉显微镜更换镜头，之后UI更新。

我们对这个场景进行了压力测试，最终得到了一个

System.Runtime.InteropServices.COMException (0x88980406)

源为PresentationCore.dll

调用堆栈是：

Message = Exception from HRESULT: 0x88980406;Category: Critical;Priority: -1;EventId: 1;

机器配置是： Microsoft Vista SP2 .Net Framework 3.5

您能否就如何解决此问题向我们提供一些意见。

1 个答案:

答案 0 :(得分：0)

正如BerndOtt建议的那样，至少在我看来，这与调整大小的HwndTarget有关。

我注释掉了这两行代码，现在我已经解决了这个问题：

HwndTarget hwndTarget = source.CompositionTarget;
hwndTarget.RenderMode = RenderMode.SoftwareOnly;

将其放入onLoaded方法，如here所示。
