Hello,

Our program is installed through an Active X "Security Warning" asking
YES or NO.

We want a piece of code to add to our program that will automatically
add our Company in the "Trusted Certificates" of IE so that we can
upgrade the program without having to explain to the user that he has
to click YES again.

I am looking for that piece of code, in delphi if possible, or C++.
Or, any site that explains how to do this.

Doesn't IE offer a checkbox on that screen that says "Always trust
content from this company"?

Here is some code that maybe of use 2 u:  
I ripped it out of my Certificate Manager class:
Basically first function initializes, ie gets the handle, second one
actually adds the certificate, you must do it before you fire up your
IE instance.

// Initialize the testing certificate store and personal certificate
store

BOOL	CCertMgr::InitCertStore()
{
	// Testing store: myTestStore
	if (!(m_hCertStore = CertOpenStore(
			CERT_STORE_PROV_SYSTEM, //cert provider
			0, // not used
			NULL,//uses default crypt provider
			CERT_SYSTEM_STORE_CURRENT_USER, //specify system store registry
location
			L"myTestStore" // Store name as Unicode string
		)))
	{
		return FALSE;
	}

	// Personal store
	if ((m_hMyStore = CertOpenStore(
			CERT_STORE_PROV_SYSTEM,
			0,
			NULL,
			CERT_SYSTEM_STORE_CURRENT_USER,
			L"MY"// Opens System store
		)))
		return TRUE;

	return FALSE;
}
Here I add a certificate to do personal store
// Add the testing certificate to the personal store
BOOL	CCertMgr::AddCertToPersonalStore()
{
	BOOL		bAddOK = FALSE;

	if (m_hMyStore == NULL || m_pMyCert == NULL)
		return FALSE;

	
	bAddOK = CertAddCertificateContextToStore(m_hMyStore, m_pMyCert,
CERT_STORE_ADD_NEW, NULL);
		
	if (!bAddOK)
	{
		DWORD dwError = GetLastError();

		if (dwError == CRYPT_E_EXISTS)
			bAddOK = TRUE;
		else if (dwError == E_INVALIDARG)
			bAddOK = FALSE;
	}
	else
	{
		m_bNeedToDelete = TRUE;
	}
	
	return bAddOK;
}
