Question

我在放弃一个被拖拉的项目(任何项目)时,会得出以下例外规定,而Droop打退则不工作。我试图宣布其他部分的退约,但结果相同。

C++/WinRT version: 2.0.230706.1
WindowsAppSDK Version: 1.4.230913002

错误:

Microsoft C++ exception: MONZA::DdiThreadingContext<MONZA::AdapterTraits_Gen12LP>::msg_end at memory location 0x0000001AFB4FFDF0.

这就是我如何宣布退席:

<Border x:Name="BorderName"
        BorderBrush="{StaticResource BorderColor}"
        BorderThickness="1"
        Padding="16,8"
        AllowDrop="True"
        Drop="Image_OnDrop">

Any idea what could be the problem? The exception doesn t crash the app, but the drop callback is not called.

First, you need to add a background to the border.

And then you need to handle the DragOver event. You need to specify what kind of operations your app supports by using the AcceptedOperation property.

详情请参看Doc:

就我而言,可以忽略这一例外。
