I'm using CreateDXGIFactory to get the graphics adapters and display modes. When I call it, it works fine and I get all the data. However, when I exit my program, the main Win32 thread exits, but something stays open because it keeps debugging. Does CreateDXGIFactory create an extra thread and I'm not closing it? I don't understand. The only thing I would suspect is that in the documentation it says it doesn't work if it's called from DllMain. It is in a DLL, but it's not called from DllMain. And it doesn't fail, either.
I'm using DirectX 11.
Here is the function that initializes DirectX. I haven't gotten past retrieving the refresh rate because of this problem. I commented everything out to pinpoint the problem.
bool CGraphicsManager::InitDirectX(HWND hWnd, int width, int height)
{
HRESULT result;
IDXGIFactory* factory;
IDXGIOutput* output;
IDXGIAdapter* adapter;
DXGI_MODE_DESC* displayModes;
DXGI_ADAPTER_DESC adapterDesc;
unsigned int modeCount = 0;
unsigned int refreshNum = 0;
unsigned int refreshDen = 0;
//First, we need to get the monitors refresh rater
result = CreateDXGIFactory(__uuidof(IDXGIFactory), (void**)&factory);
//if(FAILED(result))
//{
//MemoryUtil::MessageBoxError(TEXT("InitDirectX"), 0, 0, TEXT("Failed to create DXGI factory\nError:\n%s"), DXGetErrorDescription(result));
//return false;
//}
/*//Create a graphics card adapter
result = factory->EnumAdapters(0, &adapter);
if(FAILED(result))
{
MemoryUtil::MessageBoxError(TEXT("InitDirectX"), 0, 0, TEXT("Failed to get graphics adapters\nError:\n%s"), DXGetErrorDescription(result));
return false;
}
//Get the output
result = adapter->EnumOutputs(0, &output);
if(FAILED(result))
{
MemoryUtil::MessageBoxError(TEXT("InitDirectX"), 0, 0, TEXT("Failed to get adapter output\nError:\n%s"), DXGetErrorDescription(result));
return false;
}
//Get the modes
result = output->GetDisplayModeList(DXGI_FORMAT_R8G8B8A8_UNORM, DXGI_ENUM_MODES_INTERLACED, &modeCount, 0);
if(FAILED(result))
{
MemoryUtil::MessageBoxError(TEXT("InitDirectX"), 0, 0, TEXT("Failed to get mode count\nError:\n%s"), DXGetErrorDescription(result));
return false;
}
displayModes = new DXGI_MODE_DESC[modeCount];
result = output->GetDisplayModeList(DXGI_FORMAT_R8G8B8A8_UNORM, DXGI_ENUM_MODES_INTERLACED, &modeCount, displayModes);
if(FAILED(result))
{
MemoryUtil::MessageBoxError(TEXT("InitDirectX"), 0, 0, TEXT("Failed to get display modes\nError:\n%s"), DXGetErrorDescription(result));
return false;
}
//Now we need to find one for our screen size
for(unsigned int i = 0; i < modeCount; i++)
{
if(displayModes[i].Width == (unsigned int)width)
{
if(displayModes[i].Height == (unsigned int)height)
{
refreshNum = displayModes[i].RefreshRate.Numerator;
refreshDen = displayModes[i].RefreshRate.Denominator;
break;
}
}
}
//Store the video card data
result = adapter->GetDesc(&adapterDesc);
if(FAILED(result))
{
MemoryUtil::MessageBoxError(TEXT("InitDirectX"), 0, 0, TEXT("Failed to get adapter description\nError:\n%s"), DXGetErrorDescription(result));
return false;
}
m_videoCard = new CVideoCard();
MemoryUtil::CreateGameObject(m_videoCard);
m_videoCard->VideoCardMemory = (unsigned int)(adapterDesc.DedicatedVideoMemory);
wcstombs_s(0, m_videoCard->VideoCardDescription, 128, adapterDesc.Description, 128);*/
//ReleaseCOM(output);
//ReleaseCOM(adapter);
ReleaseCOM(factory);
//DeletePointerArray(displayModes);
return true;
}
Also, I don't know if this means anything, but this is some of the output log when the function is commented out:

P.S. I know it is CreateDXGIFactory because if I comment it out, the program exits correctly.
