从 DllMain 调用 IDirect3D9::CreateDevice() 挂起
可以有什么理由呢?
从 DLL_PROCESS_ATTACH 上的 DllMain() 调用 IDirect3D9::CreateDevice() ,它挂起的
代码很简单,就像:
BOOL APIENTRY DllMain( HMODULE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
if (ul_reason_for_call = DLL_PROCESS_ATTACH) {
IDirect3D9* d3d = Direct3DCreate9(D3D_SDK_VERSION);
D3DPRESENT_PARAMETERS pp = {};
pp.BackBufferWidth = 1;
pp.BackBufferHeight = 1;
pp.BackBufferFormat = D3DFMT_X8R8G8B8;
pp.BackBufferCount = 1;
pp.SwapEffect = D3DSWAPEFFECT_DISCARD;
pp.Windowed = TRUE;
IDirect3DDevice9* device = NULL;
HRESULT hr = d3d->CreateDevice(
D3DADAPTER_DEFAULT,
D3DDEVTYPE_HAL,
GetDesktopWindow(),
D3DCREATE_HARDWARE_VERTEXPROCESSING,
&pp,
&device);
device->Release();
d3d->Release();
}
return TRUE;
}
GetDesktopWindow() 用于简单起见,我尝试创建自己的窗口并使用它,结果相同
What can be a reason?
From DllMain() on DLL_PROCESS_ATTACH I'm calling IDirect3D9::CreateDevice() and it hangs
code is straightforward, just like:
BOOL APIENTRY DllMain( HMODULE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
if (ul_reason_for_call = DLL_PROCESS_ATTACH) {
IDirect3D9* d3d = Direct3DCreate9(D3D_SDK_VERSION);
D3DPRESENT_PARAMETERS pp = {};
pp.BackBufferWidth = 1;
pp.BackBufferHeight = 1;
pp.BackBufferFormat = D3DFMT_X8R8G8B8;
pp.BackBufferCount = 1;
pp.SwapEffect = D3DSWAPEFFECT_DISCARD;
pp.Windowed = TRUE;
IDirect3DDevice9* device = NULL;
HRESULT hr = d3d->CreateDevice(
D3DADAPTER_DEFAULT,
D3DDEVTYPE_HAL,
GetDesktopWindow(),
D3DCREATE_HARDWARE_VERTEXPROCESSING,
&pp,
&device);
device->Release();
d3d->Release();
}
return TRUE;
}
GetDesktopWindow() is used for simplicity, I tried to create own window and use it, the same result

您不能在 DllMain 中执行此类操作。具体来说,您不能从其他 DLL 调用函数。您只能在主应用程序调用导出函数时执行此操作。
引用 MSDN 上的文档:
You cannot do these kind of things in
DllMain
. Specifically, you cannot call functions from other DLLs. You can only do this from an exported function, when it is called by the main application.Quoting the docs on MSDN:
