Thanks Tracy - somebody has already done the work for me (http://www.tek-tips.com/viewthread.cfm?qid=1072829) It was just a question of finding the right thing to search (in my case foxpro localserver32) Here is the code:

* CheckServer.prg * (c) 2000, Tamar E. Granor and Della Martin * From: Microsoft Office Automation with Visual FoxPro * Hentzenwerke Publishing. www.hentzenwerke.com

LPARAMETER cServerName

LOCAL oRegistry, cClassID, cEXEName, lEXEExists, ; aClassIDValues, aClassIDValues, aServerNameValues

IF VERSION() = "Visual FoxPro 06" oRegistry = NewObject("Registry", HOME() + "FFC\Registry") ELSE SET PROCEDURE TO HOME() + "samples\classes\registry.prg" ADDITIVE oRegistry = CreateObject("Registry") ENDIF

lEXEExists = .F. DECLARE aClassIDValues[1], aServerNameValues[1]

WITH oRegistry

* Find the CLSID of the server. First, look for * the Class's Key. IF .OpenKey(cServerName + "\CLSID") = 0

* The Class's Key is open, now enumerate its values .EnumKeyValues(@aClassIDValues)

* The data portion of the first (only) value returned * is the CLSID. Find the LocalServer32 key for the CLSID IF .OpenKey("CLSID" + aClassIDValues[1,2] + "\LocalServer32") = 0

* Enumerate teh LocalServer32 values .EnumKeyValues(@aServerNameValues)

* The EXE file is stored in the first (only) data value returned. cEXEName = aServerNameValues[2]

* The value that's returned may have " -Automation" or " /Automation" or * " /AUTOMATION" & other trailing stuff at the end. Strip it off. IF "AUTO" $ UPPER(cEXEName) cEXEName = LEFT(cEXEName, ATC("AUTO", UPPER(cEXEName)) - 2) ENDIF

* Verify that the file exists lEXEExists = FILE(cEXEName)

ENDIF ENDIF ENDWITH

RETURN lEXEExists

Paul,

Once you find the MyServer.MyOLEPublicClass1, you get the value from the CLSID key. Then you'll look for the CLSID with that value. Here you'll find what you need. The InprocServer32 key will hold the filename, and usually the full path of the EXE/DLL file.

HTH, Tracy

Hi all

Let's say that I have an out-of-process automation server (MyServer.EXE)

containing OLEPUBLIC classes like MyOLEPublicClass1 etc and then I use CreateObject like this:

o = CreateObject("MyServer.MyOLEPublicClass1")

Class MyOLEPublicClass1 can determine the location of MyServer.EXE using

the _VFP.ServerName property but what I want to do is determine the location of MyServer.EXE BEFORE I use CreateObject. I imagine this should be possible via the registry (looking for an entry that refers to "MyServer.MyOLEPublicClass1" but I cannot get further than that.

Any ideas ? Thanks

Paul Newton
