c⌒っﾟДﾟ)っ 我注入的是IMGUI的官方demo程序 “example_win32_directx11.exe” 当中，代码也是按照官方demo的更改尺寸写的，但是ResizeBuffers就是不成功
static void CleanupRenderTarget() {
client.render.pD3dDeviceContext->ClearState();
client.render.pD3dDeviceContext->Flush();
if (client.render.pRenderTargetView)
{
client.render.pRenderTargetView->Release();
client.render.pRenderTargetView = nullptr;
}
::Sleep(100);
}
static void CreateRenderTarget() {
ID3D11Texture2D* pBackBuffer = nullptr;
HRESULT hr = client.render.pSwapChain->GetBuffer(0, __uuidof(ID3D11Texture2D), (LPVOID*)&pBackBuffer);
if (SUCCEEDED(hr))
{
client.render.pD3dDevice->CreateRenderTargetView(
pBackBuffer,
0,
&client.render.pRenderTargetView);
pBackBuffer->Release();
}
}
