[sowrav]

Hi,

i am trying to test the ECom example given in the sdk in .net IDE with carbide 2.0.1. Though i could build the console application successfully while running its giving -1(Not found) error. Does ecom works with carbide? where should rsc and implementation dll be placed for emulator. can anyone help me please

Thanks mitt for your reply.its working fine.

I don't think it needs any special capabilities, at least didn't see any problems on running mine in emulator. Only requirement that I found out was that it seems to require trusted UID.

What do you mean by "trusted UID"? Do you mean protected UID range?

Looking at SIP example in SDK and its ECom plugin's registration file A00001EC.rss, it uses implementation_uid = 0xA00001EC, which is from unprotected range.

[symbianyucca]

yep that's what I was supposed to say. Anyway, though it is said that MMF plugins are not supported, I tried making one and got it working in emulator pretty well.

Anyway, it seemed to require ProtServ before it was recognized in the phone.

I tested ECom plugin - no protected UID required. I use UID from Axxxxxxx range, and it works.

And yes, you need ProtServ capability, which is probably needed by all ECom plugins.

Hi, worked with capability NONE for me.

[pkosonen]

But doesn't work with UID from unprotected range!

[mike.b]

Works for me with UID Axxxxxxx, tested also on real device.

[pkosonen]

Got a newer image to my phone and unprotected UID worked for me also with RND certificate.
The crazy part is that if I use self signing or developer certificate I get an error "Cannot grant capabilities" (I have CAPABILITY NONE) but if I use RND certificate everything works fine.

What certificate and capabilities have you used?

"It's a wonderful, wonderful world..."

[mike.b]

Self-created certificate, and 0 caps in exe.

[pkosonen]

How is that possible? You've said that ProtServ is required for the ECom, but with self signing You can get only the following capabilities:

"The following user capabilities can be granted with user's confirmation when the signature is not valid:
LocalServices NetworkServices ReadUserData WriteUserData UserEnvironment
This applies also in the case of self-signed certificates."

Of course the application can be self signed but the ECom can't be.

Or am I missing something here?

[mike.b]

As I know, you sign SIS file, not executable or dll.

Ecom plugin is actually DLL + registration file. The ECom DLL is not run directly, but this is loaded by ECom framework, and the DLL is then assigned capabilities of process that loaded it.
Normally DLL must have equal or greater capabilities than executable that loads it. ECom dll's are exception to this rule.

I'm not sure if ProtServ capability is needed for ECom dll, but I've seen that in recognizer example and some other examples, so I used it. I suppose it should work with zero capabilities too.
