由什么决定RegisterTypeLib是写入win32还是win64? [英] What decides whether RegisterTypeLib writes to win32 or win64?

问题描述

我正在处理两个基于ATL的COM项目.

I am working with two ATL-based COM projects.

两者都实现DllRegisterServer只是

STDAPI DllRegisterServer(void)
{
  // registers object, typelib and all interfaces in typelib
  return _Module.RegisterServer(TRUE);
}

最终打电话给

::RegisterTypeLib(pTypeLib, bstrPath, szDir);

atlbase.h:6516.

in atlbase.h:6516.

但是由于某种原因，此调用使项目之一得以创建

But for some reason this call makes one of the projects create

HKEY_CLASSES_ROOT\TypeLib\<guid>\<version>\0\win64

在Windows 7 32位系统上使用regsvr32.exe注册时

when registered using regsvr32.exe on Windows 7 32 bit.

另一个项目正确创建

HKEY_CLASSES_ROOT\TypeLib\<guid>\<version>\0\win32

.

我应该从哪里开始寻找并解决此问题?

Where should I start looking to find and fix this behavior?

推荐答案

类型库很有可能是针对win64平台的. 检查类型库的属性.可以通过 ITypeLib访问它们: :GetLibAttr :

It is strongly possible, that the typelibrary is targeted for the win64 platform. Check the typelibary's attributes. One may access them via ITypeLib::GetLibAttr:

ITypeLib::GetLibAttr(TLIBATTR **ppTLibAttr)

TLIBATTR结构的字段类型为 SYSKIND .它包含一个指示平台的值.

The TLIBATTR structure has a field of type SYSKIND. It contains a value which indicates the platform.

typedef enum tagSYSKIND {
  SYS_WIN16   = 0,
  SYS_WIN32   = ( SYS_WIN16 + 1 ),
  SYS_MAC     = ( SYS_WIN32 + 1 ),
  SYS_WIN64   = ( SYS_MAC + 1 ) 
} SYSKIND;

我希望这可以帮助您解决问题
