Object doesn't support this property or method

[asd78fg]

I'm developing a DLL in C++ that is accessed from an ASP page. When running the page this error is thrown:

Object doesn't support this property or method: 'ldap_obj.objectVersion'

The method objectVersion() does exist; as I browse component services I can see that method for my object. Plus, all other methods in the object work perfectly, so I assume it to be a problem with the C++ side of everything. I am at a loss as to what may be causing this error. Does anyone have any suggestions?

The C++ code:
STDMETHODIMP Cuserinfo:bjectVersion(long *versionNumber)
{
*versionNumber = 2;
return S_OK;
}

The line in the ASP file that is throwing the error:
versionNumber = ldap_obj.objectVersion()

are you actually using the method without sending in a parameter as in the sample you submitted?

versionNumber = ldap_obj.objectVersion()

If so, you have to send a pointer to your long variable (or the addressof)

The long variable versionNumber is an [out, retval] variable in this object -- a long value is used similarly in other methods of this object without requiring a value to be passed in (as a value is passed out through it). Theoretically, versionNumber() should be the correct way of calling this function, then.

Besides, even when I try passing a value, it throws the same error.

sorry, didn't know that. The only other thing I can think of is that the actual function is private or protected, for internal implementation only (maybe a mistake).

No reason you would have known that -- I neglected to mention it . That the method may be private is an excellent suggestion, but the only place I see any indication of that is in the header file that defines this object, and this method is listed among the public functions there. In addition, if it were private, I think it would not show up in Component Services under the object's interface. I might be mistaken about that, though, as I am still really new to this.

Some new information:

After more fiddling around, it seems that I can not add ANY new method. I copied/pasted a method known to work, renaming the new copy. Once again the method is seen in the Component Services browser, but when I try to call it from the ASP page, I get the same error as before. What's more, if I call the method that worked (the one that got copied), it works fine... only its clone fails.

So it looks as though somehow new methods I create can be seen, but can not be called. Any idea as to why this might happen?
