Windows XP 上的 Direct3D ID3DXFont->DrawText 崩溃

我正在尝试从文件加载字体，然后在 Direct3D 中使用它，它在我的 Windows 7 计算机上完美运行，但如果我在 XP SP2 计算机上尝试它，第一次调用 DrawText 将返回 0（意味着失败），第二次尝试将导致程序崩溃。

Windows XP 上的 Direct3D 中导入的字体是否有一些限制？有没有办法获得一些有用的错误代码，因为 DrawText 返回 0 本身并不是很有帮助。

作为参考，这是我的字体导入代码：

if (AddFontResourceEx("ttfFiles/tf2Build.ttf", FR_PRIVATE, 0) == 0) {
    // Throw exception.
}

这是我创建 ID3DXFont 对象的方法（它也没有问题地返回）：

HRESULT result = D3DXCreateFont(
    d3dDevice_,
    height,
    0, 
    isBolded ? FW_BOLD : FW_NORMAL,
    0,
     false,
    DEFAULT_CHARSET,
    OUT_DEFAULT_PRECIS,
    DEFAULT_QUALITY,
    FF_DONTCARE,
    name.c_str(),
    &d3dFont );

if ( FAILED( result ) ) {
    // Throw exception.
}

编辑： 我设法让它发生在XP 中的调试器，出现了一个非常可怕的错误：

DirectFont.exe 中发生类型为“System.AccessViolationException”的未处理异常附加信息：尝试读取或写入受保护的内存。这通常表明其他内存已损坏。

这是堆栈跟踪：

usp10.dll!ClientData::GetOtlTable() + 0x35 字节
usp10.dll!otlResourceMgr::getOtlTable() + 0x7a 字节
usp10.dll!SubstituteOtlChars() + 0x1af 字节
usp10.dll!OtlShape() + 0x3c5 字节
D3DX9_43.dll!D3DXCore::CFont::DrawTextAW() + 0x5aa 字节 D3DX9_43.dll!D3DXCore::CFont::DrawTextA() + 0x26 字节

原文

I'm trying to load a font from a file and then use it in Direct3D, and it works perfectly on my Windows 7 machine, but if I try it on an XP SP2 machine, the first call to DrawText will return 0 (meaning it failed), and the second time it tries will cause the program to crash.

Are there some restrictions with imported fonts in Direct3D on Windows XP? Is there a way I can get some useful error code, since DrawText returning 0 isn't very helpful on its own.

For reference, here's my font importing code:

if (AddFontResourceEx("ttfFiles/tf2Build.ttf", FR_PRIVATE, 0) == 0) {
    // Throw exception.
}

And here's how I create the ID3DXFont object (which also returns without a problem):

HRESULT result = D3DXCreateFont(
    d3dDevice_,
    height,
    0, 
    isBolded ? FW_BOLD : FW_NORMAL,
    0,
     false,
    DEFAULT_CHARSET,
    OUT_DEFAULT_PRECIS,
    DEFAULT_QUALITY,
    FF_DONTCARE,
    name.c_str(),
    &d3dFont );

if ( FAILED( result ) ) {
    // Throw exception.
}

Edit: I managed to get it to occur under a debugger in XP, and here's the quite scary error that appears:

An unhandled exception of type 'System.AccessViolationException' occured in DirectFont.exe
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

And here is the stack trace:

usp10.dll!SubstituteOtlChars() + 0x1af bytes
