I cannot instantiante activex component from vb.net (Cannot create ActiveX component) but in vbs yes
יום חמישי 29 ספטמבר 2011 12:28Hi everyone.
I really stuck and I don't know how to fix it.
You see, I create from server (windows Server 2003, service pack 2 ) a com+ application. I am in the domain from the active directory. I connected to the server with another accout, also from the same domain.
once that I created the com+ application proxy, I copied the MSI and cab files to my computer (Windows xp sp 3) and I installed the COM+.
I create a test.vbs, with:
Set a = CreateObject("ComProxy.ClasePrueba")
Here, the vbs works fine, ok.
But, when I try to do the same in vb.net in visual studio 2003, I got the well know 429 error "Cannot create ActiveX component"
I tried a thousand times with little variances int he process, with the same result. This drive me crazy.
Another guy, (also Windows xp sp 3) in his machine can instances the com+ app.
Both accounts haven't permissions to connect to the server (that's why we connect with a generic account)
I watch the dcomcnfg and both have the same configuration, same limits (allow local and remote access to Everyon) , both activate to the same ip address.
Any idea? someone else has had this error?
I tried to clean up the stack of the wrapper, but I don't know how.
I add the the "Imports System.Runtime.InteropServices" in namespace
I put the next line before call the CreateObject statement
but is wrong, Does anybody knows how can I clean the heap of the wrapp class?
Thanks in advance!
Any suggestion will be appreciated
Muss ist sein?? ... Ist muss sein!!!!!... Aber, ist konnte auch andere sein.......
