That's basically my question. Under the GRE key there's a GreHome
value which holds the directory I want. I have no problem enumerating
these keys, the thing I don't know how to do is find which of the GRE
registered is the one that was installed with NS7.
I later noticed the AppList subkey and I now look to see if Netscape
is listed there. Here is my code, is it correct?
I assume that if a subkey begins with "Netscape 7" it's what I'm
looking for and that there aren't several versions of Netscape 7+
installed on the machine.
// Look in the AppList sub key to see if this is
// the GRE with which Netscape is associated.
bool IsNetscapeGRE(HKEY key)
{
CRegKey AppList;
LONG rc = AppList.Open(key, _T("AppList"), KEY_READ);
if (ERROR_SUCCESS != rc)
return false;
DWORD count, maxLen;
rc = RegQueryInfoKey(AppList, NULL, NULL, NULL, &count,
&maxLen, NULL, NULL, NULL, NULL,
NULL, NULL);
if (ERROR_SUCCESS != rc)
return false;
// ignore minor versioning (is this right?) <==== QUESTION
const CString Netscape = _T("Netscape 7");
CString buffer; // manage memory
TCHAR* name = buffer.GetBuffer(maxLen + 1);
for (int i = 0; i < count; ++i) {
DWORD len = maxLen + 1;
rc = RegEnumKeyEx(AppList, i, name, &len, NULL,
NULL, NULL, NULL);
if (ERROR_SUCCESS != rc)
continue;
// Check if 'name' begins with the Netscape string.
CString actual(name, Netscape.GetLength());
if (actual.CompareNoCase(Netscape) == 0)
return true;
}
return false;
}
