我最终能够让 VS 6 在 Win 8 和 Win 10 上运行。基本步骤如下：
在 \Windows 中创建一个名为 msjava.dll 的虚拟文件。（例如，“echo >msjava.dll”）如果没有这一步，VS 6 安装程序就不会走得太远。
安装 VS 6 和 SP 6。
将 MSDEV.EXE 重命名为其他名称，例如 MSDEVQ.EXE。
为排除容错堆填充程序的 MSDEVQ 创建兼容性数据库。如果没有这一步，调试大量使用 HeapAlloc 等的程序会非常缓慢。
对于调试，请确保在对 OLE32 进行任何调用之前触发断点。我在主程序的早期或（对于 MFC 应用程序）InitInstance 函数中包含以下标头：
X64DebugHack.h：
#ifdef _DEBUG
// In order to be able to debug this application on x64, we need to single
// step across at least one statement before ole32.dll gets loaded. So
// always leave this breakpoint in place.
requiredbreakpoint:
int junkola = 42;
// Check to see that there was a breakpoint...
PUCHAR pjunk;
_asm lea eax, requiredbreakpoint
_asm mov pjunk, eax
if (*pjunk != 0xCC)
AfxMessageBox("Required breakpoint was not set prior to loading OLE32.DLL -- single stepping will not be possible during this debugging session.", MB_OK | MB_ICONHAND, 0);
LoadLibrary("OLE32");
#endif
- 编写一个提供“停止调试”按钮的扩展 DLL。该扩展必须搜索和销毁调试句柄，这些句柄在 Win64 中的句柄类型与在 Win32 中的不同。编写扩展的机制超出了本论坛的范围，但实际工作的代码在这里：
CCommands::HelpAssistantKill:

BSTR bsStopDebugging = SysAllocString(L"DebugStopDebugging");
if (!bsStopDebugging)
break;

SysFreeString(bsStopDebugging);
if (hr != 0)
break;
} // do once
while (FALSE);
if (phi)
delete[] phi;
if (hDll)
FreeLibrary(hDll);
if (!didit)
{ // didn't do anything
MessageBox(NULL, "Unable to find and close any debug object handles", "HelpAssistant", MB_OK | MB_ICONINFORMATION);
} // didn't do anything
return S_OK;
} // CCommands::HelpAssistantKill
这感觉像是一项非常英勇的努力，但我在 VS 6 上构建了大约一百万行代码，我必须继续工作。现在我已经为 VS 2015 构建了一个可行的宏处理器，我可以对这个应用程序进行转换。
