Webmaster Forum / ColdFusion / Advanced Techniques / January 2006

Hello Everyone,

I am trying to access VSS Automation APIs through coldfusion to find out the
version of a file

        <cfobject   type    = "COM"  
                           action  = "create"  
                           class   = "SourceSafeTypeLib.VSSDatabase"  
                          name    = "vss">

        <cfscript>
             vss.open("\\servername\SRCSAFE.INI", "username", "password");
            Ver = vss.VSSItem("$\filepath\filename.cfm").VersionNumber();
       </cfscript>
       <cfoutput>#Ver#</cfoutput>

However, I get following error

The cause of this exception was that:
coldfusion.runtime.com.ComObjectInstantiationException: An exception occurred
when instantiating a Com object..  
 
The error occurred in E:\TestDir\test.cfm: line 21
 
Called from E:\TestDir\test.cfm: line 21
 
19 :         <cfobject   type    = "COM"  
20 :                     action  = "create"  
21 :                     class   = "SourceSafeTypeLib.VSSDatabase"  
22 :                     name    = "vss">
23 :     </cfcatch>

I have installed VSS client on the WebServer. So all the required DLLs should
be available. To Verify, I tried to access the same VSS Automation APIs through
VB, compiled an exe and it worked fine on the same server.

Am I missing something?

TIA
