如何在wince下注册COM组件？

[duguqiubai0823]

如题目所示，我想在Wince下面注册COM组件，应该使用什么命令呀？

你可以，loadlibrary , getProcAddress, 然后调用DllRegisterServer，试一下吧，结果告诉我，[e-mail]

//先反注册
LPCTSTR strFileName;
strFileName=TEXT("\\Windows\\my.dll");

typedef (WINAPI * UNREGISTER_FUNC) (void);
UNREGISTER_FUNC MyFunc=NULL;
HMODULE hModule=::LoadLibrary(strFileName);
if(hModule)
{
MyFunc=(UNREGISTER_FUNC)GetProcAddress(hModule,L"DllUnregisterServer");
if(MyFunc==NULL)
{
MessageBox(NULL,TEXT("can't find 'DllUnregisterServer' func!"),TEXT("Error"),MB_OK);
}
else
{
MyFunc();
MessageBox(NULL,TEXT("Unregister dll ok!"),TEXT("Error"),MB_OK);
}
::FreeLibrary(hModule);
}
//注册
typedef (WINAPI * REGISTER_FUNC) (void);
REGISTER_FUNC MyFunc2=NULL;
HMODULE hModule2=::LoadLibrary(strFileName);
if(hModule2)
{
MyFunc2=(REGISTER_FUNC)GetProcAddress(hModule2,L"DllRegisterServer");
if(MyFunc2==NULL)
{
MessageBox(NULL,L"can't find 'DllRegisterServer' func!",TEXT("Error"),MB_OK);
}
else
{
MyFunc2();
MessageBox(NULL,L"register dll ok!",TEXT("Ok"),MB_OK);
}
::FreeLibrary(hModule2);
}
//更新注册表

lRet = RegSetValueEx(hKey, (LPCTSTR)wszName3, 0, REG_SZ, (LPBYTE)lpData, dwDataSize);
delete [] lpData;
}

RegCloseKey(hKey);

}

我那个帖子的问题，也帮我看看。。。

[henryxuv]

我的CE下，根本没有这个程序！！楼主的问题解决了么？？

[xinlanr]

直接调用 REGSVRCE.EXE

在开始->运行里输入 REGSVRCE 你的dll名称 就可以

[zzxblsy]

楼主的问题解决了没有啊？？我也遇到相似的问题，我用5.0的IImage接口做了一个图片显示的程序，在模拟器上运行的很好。。但是down到机器上却跑不了了，CoCreateInstance函数的返回值显示是因为类没有注册。。。汗啊，不知道怎么在ce下注册。
