Hi guys I'm new to the COM World. I'm coding in X++ on Microsoft Axapta and I'd like to find out if a com object is available for a specific methods: StgOpenStorageEx and probably IPropertySetStorage both located in the OLE32.dll.

The class name of a COM object is supposed to be either its ProgID (programmatic identifier) or CLSID (class identifier):

ProgIDs have the following format: <program>.<component>.<version> (e.g. "AXAPI.Axapta.1 "). Note that the version element of the ProgID can often be omitted.

CLSIDs are 128 bit values and have to following format: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} (e.g. "{80F444A1-46FF-11D2-8459-0008C7A0D1EA}").

The thing is I don’t know the <program>.<component> format for the methods I'm looking for (StgOpenStorageEx and IPropertySetStorage) and I don’t know any possible CLSID ether.

I obviously need more info on how to access a specific COM and there format.  I'm not expecting any one to know X++ or to past me X++ code because X++ is applicable only to Axapta ERP developed by Navision with Microsoft an recently purchase by Microsoft.

If you guys have references or examples in any language I would appreciate it a lot
Thx for you feedbacks

In your example, AXAPI is actually the component, and Axapta is the class; there is a 1-1 correspondence between CLSID and Axapta.

If you want to dig around, and you have Visual Studio, go into the Tools (not the Enterprise tools) menu and select OLE View.  That will give you the OLE/COM Object viewer, which will let you peek into everything.

VB example:



Good Luck,
