Under normal (well written) circumstances, the COM callable wrapper (CCW) can take care of everything. I'll try to reproduce the steps the VB Script uses to access the COM object. Hi all, I have an excel workbook open in excel and I know its full path/Name I want to get a COM pointer to the open workbook from my VB6 application In addition, not all monikers need to support persistence, which means that the methods of the IPersist andIPersistStream interfaces might simply return E_NOTIMPL.

I would learn how to reproduce the functionality of the scripts using C++, COM and WTL templates.

This is probably how VB Script extracts property values accessed using this syntax: IIsObject.AnonymousUserName. Like the BindMoniker function, CoGetObject obviates the need for an explicit binding context. Return codeDescription S_OK The object was created successfully.

Can you post a small code example ? The most common reasons for returning this value are that a password is needed or that a floppy needs to be mounted. At other times, only a custom moniker will do. http://helpnet.flexerasoftware.com/installshield21helplib/Subsystems/installshield21langref/helplibrary/CoGetObject.htm Posting Permissions You may not post new threads You may not post replies You may not post attachments You may not edit your posts BB code is On Smilies are

I decided some of the features are compelling enough to move. Then it calls the IMoniker::BindToObject method of the moniker to obtain a pointer to the object requested by the Visual Basic programmer in the string passed to GetObject.

MkParseDisplayName has hard-coded support for file monikers and thus knows that any pathname should be converted to a file moniker. Essence of technology the CATFISH wrote:In the presence of this function creation of a new gorilla is reduced to simple finding of object of a class and method call CreateInstance:HRESULT CreateAGorillaAndEatBanana The template call // has greatly simplified the QueryInterface call.

It depends only on your preference. Often, the only way to communicate with legacy software is via a COM interface.

MkParseDisplayName accepts two primary string formats. BTW You might want to read Don Box's article on this from the 7/97 MSJ. It tells the API call what COM Interface ID you are looking for.

For example, an item moniker returns this value if its container does not support the IOleItemContainer interface. Instead of using a CLSID or marshaled interface pointer, monikers employ a somewhat user-friendly string called a display name to identify COM+ objects. How much I understood this parameter (display name) should look like something type "clsid:AD0B0000-A37C-6EFC-10C7-3435345A34E5". 3 Reply by Antonariy 2012-06-28 18:02:56 Antonariy Member Offline Registered: 2008-07-16 Posts: 11,383 Re: Problem with CoGetObject The COM+ library of API primitives is defined in the com.ms.win.Ole32 class, of which CoGetObject is a method.

Instead, the J/Direct feature of the Microsoft Java Virtual Machine (VM) enables Java programs to call native Win32 API functions; you can use it to directly invoke the standard CoGetObject function. The key questions I wanted to answer are:How do you open the "IIS://LocalHost/w3svc" object in C++?What is the C++ equivalent to GetObject?The trick is to answer the second question first.
