求助关于DLL和OCX文件的注册问题！

[dida]

问题是这样：我已经写好了DLL和OCX文件，现在客户浏览网页的时候需要调用我写的DLL和OCX文件，请问怎样才能将DLL和OCX下载到客户端并在客户端注册？

[929]

我想如果在网页上放了ACTIVEX控件，如果浏览器用户允许，它可以自动注册，不过你要在网页的OBJECT说明中指明如机器上没有此控件，它下载的位置，这可在CODEBASE属性中说明。

[我也看不穿]

我也关心这个问题

[softdoctor]

很简单：
在网页上你的OBJECT的CODEBASE属性设为
"http://www.youweb.com.cn/download/youdll.dll"
或
"http://www.youweb.com.cn/download/youdll.cab"
如果客户机器上没有该控件浏览器将自动下载安装。
cab是你控件的打包文件，IE支持cab,可大大加快下载速度。

无论是DLL,OCX都必须有数字签名，否则浏览器安全检验通不过
除非客户将你的站点设为信任站点或将INTERNET安全级别设为
最底。

好象在第一次浏览到时IE会自动下载并注册，所以第一次浏览时速度会很慢，以后就快了

我对ocx的安装密码很感兴趣，我曾用过别人的一个功能很强的控件，在安装后不能正确注册，因为有密码！

[freehero]

能不能在程序中自动设置某一个站点为可信任站点，从而ie不在提示没有数字签名！

softdoctor说得非常正确，除此之外别无它法。因为我以前也写过在网页上用的控件。

[wenfeng]

我也认为SOFTDOCTOR说的非常正确

[royluo]

freehero，你的愿望很好，不过只能是愿望了。
softdoctor说得非常正确
需要补充的是，如果是NT，不管浏览器的安全级别是什么
只要没有数字签名，它都不会下载

这样就不会有提示了：
1:先添加三个全局函数
// Helper function to create a component category and associated description
HRESULT CreateComponentCategory(CATID catid, WCHAR* catDescription)
{
ICatRegister* pcr = NULL ;
HRESULT hr = S_OK ;
hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,
NULL, CLSCTX_INPROC_SERVER, IID_ICatRegister, (void**)&pcr);
if (FAILED(hr))
return hr;
// Make sure the HKCR\Component Categories\{..catid...}
// key is registered
CATEGORYINFO catinfo;
catinfo.catid = catid;
catinfo.lcid = 0x0409 ; // english
// Make sure the provided description is not too long.
// Only copy the first 127 characters if it is
int len = wcslen(catDescription);
if (len>127) len = 127;
wcsncpy(catinfo.szDescription, catDescription, len);
// Make sure the description is null terminated
catinfo.szDescription[len] = '\0';
hr = pcr->RegisterCategories(1, &catinfo);
pcr->Release();
return hr;
}

// Helper function to register a CLSID as belonging to a component category
HRESULT RegisterCLSIDInCategory(REFCLSID clsid, CATID catid)
{
// Register your component categories information.
ICatRegister* pcr = NULL ;
HRESULT hr = S_OK ;
hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,
NULL, CLSCTX_INPROC_SERVER, IID_ICatRegister, (void**)&pcr);
if (SUCCEEDED(hr))
{
// Register this category as being "implemented" by
// the class.
CATID rgcatid[1] ;
rgcatid[0] = catid;
hr = pcr->RegisterClassImplCategories(clsid, 1, rgcatid);
}
if (pcr != NULL)
pcr->Release();
return hr;
}

// Helper function to unregister a CLSID as belonging to a component category
HRESULT UnRegisterCLSIDInCategory(REFCLSID clsid, CATID catid)
{
ICatRegister* pcr = NULL ;
HRESULT hr = S_OK ;
hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,
NULL, CLSCTX_INPROC_SERVER, IID_ICatRegister, (void**)&pcr);
if (SUCCEEDED(hr))
{
// Unregister this category as being "implemented" by
// the class.
CATID rgcatid[1] ;
rgcatid[0] = catid;
hr = pcr->UnRegisterClassImplCategories(clsid, 1, rgcatid);
}

if (pcr != NULL)
pcr->Release();
return hr;
}

2:将控件类的UpdateRegistry(BOOL bRegister)函数替换如下：
BOOL CLCCBatmanCtrl::CLCCBatmanCtrlFactory::UpdateRegistry(BOOL bRegister)
{
// TODO: Verify that your control follows apartment-model threading rules.
// Refer to MFC TechNote 64 for more information.
// If your control does not conform to the apartment-model rules, then
// you must modify the code below, changing the 6th parameter from
// afxRegApartmentThreading to 0.

if (bRegister)
{
HRESULT hr = S_OK;
//register as Safe for Scripting
hr = CreateComponentCategory(CATID_SafeForScripting,
L"Controls that are safely scripting");
if(FAILED(hr))
return FALSE;

hr = RegisterCLSIDInCategory(m_clsid,CATID_SafeForScripting);
if(FAILED(hr))
return FALSE;

//register as safe for initializing
hr = CreateComponentCategory(CATID_SafeForInitializing,
L"Controls safely initializing form persistent data");
if(FAILED(hr))
return FALSE;

hr = RegisterCLSIDInCategory(m_clsid,CATID_SafeForInitializing);
if(FAILED(hr))
return FALSE;

return AfxOleRegisterControlClass(
AfxGetInstanceHandle(),
m_clsid,
m_lpszProgID,
IDS_LCCBATMAN,
IDB_LCCBATMAN,
afxRegApartmentThreading,
_dwLCCBatmanOleMisc,
_tlid,
_wVerMajor,
_wVerMinor);
}
else
{
HRESULT hr = S_OK;

hr = UnRegisterCLSIDInCategory(m_clsid,CATID_SafeForScripting);
if(FAILED(hr))
return FALSE;

hr = UnRegisterCLSIDInCategory(m_clsid,CATID_SafeForInitializing);
if(FAILED(hr))
return FALSE;

return AfxOleUnregisterClass(m_clsid, m_lpszProgID);
}
}
OK!
