Question

所以，我在OpenGL中构建一个默认上下文，（没有扩展），出于某种原因，只要我的窗口打开，我就会出现“意外内核模式陷阱”的错误

现在，这是非常默认的。因为我刚刚使用了启动VS 2015社区win32应用程序，并逐字应用了OpenGL上下文代码。其中包括一个消息框，据说应该向我展示我的OpenGL版本（4.4）。但是，它打开空白，在关闭时，它应该打开OpenGL CS_DCOWN窗口，我是BSOD。

只是想知道是否有人能够了解具体导致BSOD的命令，或者我的做法是否错误？

Answer 1

据我了解，GetDC应该失败，因为仍然没有为此窗口创建客户区 - 第一个窗口消息是WM_NC_CREATE，这对于客户来说太早了区域操纵。

您只能在WM_CREATE之后执行D3D代码。
