我正在尝试使用以下代码：
HRESULT hResult;
HDC hDC;
IDXGISurface1 *pSurface = NULL;
hResult = m_flashTexture->QueryInterface(__uuidof(IDXGISurface1), (void**)&pSurface);
hResult = pSurface->GetDC(TRUE, &hDC);
assert(SUCCEEDED(hResult));
m_flashPlayer->DrawFrame(hDC);
drawFrame是......
void CFlashDXPlayer::DrawFrame(HDC dc)
{
if (m_dirtyFlag)
{
IViewObject* pViewObject = NULL;
m_flashInterface->QueryInterface(IID_IViewObject, (LPVOID*) &pViewObject);
if (pViewObject != NULL)
{
// Combine regions
HRGN unionRgn, first, second = NULL;
unionRgn = CreateRectRgnIndirect(&m_dirtyRects[0]);
if (m_dirtyRects.size() >= 2)
second = CreateRectRgn(0, 0, 1, 1);
for (std::vector<RECT>::iterator it = m_dirtyRects.begin() + 1; it != m_dirtyRects.end(); ++it)
{
// Fill combined region
first = unionRgn;
SetRectRgn(second, it->left, it->top, it->right, it->bottom);
unionRgn = CreateRectRgn(0, 0, 1, 1);
CombineRgn(unionRgn, first, second, RGN_OR);
DeleteObject(first);
}
if (second)
DeleteObject(second);
RECT clipRgnRect; GetRgnBox(unionRgn, &clipRgnRect);
RECTL clipRect = { 0, 0, m_width, m_height };
// Fill background
if (m_transpMode != TMODE_FULL_ALPHA)
{
// Set clip region
SelectClipRgn(dc, unionRgn);
COLORREF fillColor = GetBackgroundColor();
HBRUSH fillColorBrush = CreateSolidBrush(fillColor);
FillRgn(dc, unionRgn, fillColorBrush);
DeleteObject(fillColorBrush);
// Draw to main buffer
HRESULT hr = pViewObject->Draw(DVASPECT_TRANSPARENT, 1, NULL, NULL, NULL, dc, &clipRect, &clipRect, NULL, 0);
assert(SUCCEEDED(hr));
}
else
{
if (m_alphaBlackDC == NULL)
{
// Create memory buffers
BITMAPINFOHEADER bih = {0};
bih.biSize = sizeof(BITMAPINFOHEADER);
bih.biBitCount = 32;
bih.biCompression = BI_RGB;
bih.biPlanes = 1;
bih.biWidth = LONG(m_width);
bih.biHeight = -LONG(m_height);
m_alphaBlackDC = CreateCompatibleDC(dc);
m_alphaBlackBitmap = CreateDIBSection(m_alphaBlackDC, (BITMAPINFO*)&bih, DIB_RGB_COLORS, (void**)&m_alphaBlackBuffer, 0, 0);
SelectObject(m_alphaBlackDC, m_alphaBlackBitmap);
m_alphaWhiteDC = CreateCompatibleDC(dc);
m_alphaWhiteBitmap = CreateDIBSection(m_alphaWhiteDC, (BITMAPINFO*)&bih, DIB_RGB_COLORS, (void**)&m_alphaWhiteBuffer, 0, 0);
SelectObject(m_alphaWhiteDC, m_alphaWhiteBitmap);
}
HRESULT hr;
HBRUSH fillColorBrush;
// Render frame twice - against white and against black background to calculate alpha
SelectClipRgn(m_alphaBlackDC, unionRgn);
COLORREF blackColor = 0x00000000;
fillColorBrush = CreateSolidBrush(blackColor);
FillRgn(m_alphaBlackDC, unionRgn, fillColorBrush);
DeleteObject(fillColorBrush);
hr = pViewObject->Draw(DVASPECT_TRANSPARENT, 1, NULL, NULL, NULL, m_alphaBlackDC, &clipRect, &clipRect, NULL, 0);
assert(SUCCEEDED(hr));
// White background
SelectClipRgn(m_alphaWhiteDC, unionRgn);
COLORREF whiteColor = 0x00FFFFFF;
fillColorBrush = CreateSolidBrush(whiteColor);
FillRgn(m_alphaWhiteDC, unionRgn, fillColorBrush);
DeleteObject(fillColorBrush);
hr = pViewObject->Draw(DVASPECT_TRANSPARENT, 1, NULL, NULL, NULL, m_alphaWhiteDC, &clipRect, &clipRect, NULL, 0);
assert(SUCCEEDED(hr));
// Combine alpha
for (LONG y = clipRgnRect.top; y < clipRgnRect.bottom; ++y)
{
int offset = y * m_width * 4 + clipRgnRect.left * 4;
for (LONG x = clipRgnRect.left; x < clipRgnRect.right; ++x)
{
BYTE blackRed = m_alphaBlackBuffer[offset];
BYTE whiteRed = m_alphaWhiteBuffer[offset];
m_alphaBlackBuffer[offset + 3] = 255 - (whiteRed - blackRed);
offset += 4;
}
}
// Blit result to target DC
BitBlt(dc, clipRgnRect.left, clipRgnRect.top,
clipRgnRect.right - clipRgnRect.left,
clipRgnRect.bottom - clipRgnRect.top,
m_alphaBlackDC, clipRgnRect.left, clipRgnRect.top, SRCCOPY);
}
DeleteObject(unionRgn);
pViewObject->Release();
}
m_dirtyFlag = false;
m_dirtyRects.clear();
m_dirtyUnionRect.left = m_dirtyUnionRect.top = LONG_MAX;
m_dirtyUnionRect.right = m_dirtyUnionRect.bottom = -LONG_MAX;
}
}
我还应该提一下，我使用以下方法设置了m_flashTexture：
D3D11_TEXTURE2D_DESC textureDesc;
ZeroMemory(&textureDesc, sizeof(textureDesc));
textureDesc.Width = width;
textureDesc.Height = height;
textureDesc.MipLevels = 1;
textureDesc.ArraySize = 1;
textureDesc.Format = DXGI_FORMAT_B8G8R8A8_UNORM;
textureDesc.SampleDesc.Count = 1;
textureDesc.Usage = D3D11_USAGE_DEFAULT;
textureDesc.BindFlags = D3D11_BIND_SHADER_RESOURCE | D3D11_BIND_RENDER_TARGET;
textureDesc.MiscFlags = D3D11_RESOURCE_MISC_GDI_COMPATIBLE;
HRESULT hr = device->CreateTexture2D(&textureDesc, NULL, &m_flashTexture);
每当我运行这段代码时（还有更多的东西，但是它被埋在其他一些类中，如果你认为别的东西会有用，请告诉我。）我得到了一个蓝色的死亡屏幕在flashPlayer-＆gt; drawFrame（）函数中。我不知道造成蓝屏的原因。
任何想法或任何人都会看到突出的东西，看起来会导致蓝屏？
感谢。

有谁知道这意味着什么？
答案 0 :(得分：0)
每当你编写用户空间应用程序并导致BSoD时，某些内核级代码肯定存在错误（无论是windows内核本身，还是某些驱动程序，在这种情况下，它看起来像igdpmd64.sys） 。简而言之，由于用户空间应用程序所做的事情，操作系统永远不会在任何情况下崩溃。所以我会研究一下这个驱动程序是否有升级。
但是，您的代码中也可能存在错误地使用DirectX并触发此驱动程序错误的错误。
当然，我会尝试创建一个绝对最小的完整程序来触发崩溃。至少你可以把它提交给司机作家。
