Dataport,NetworkControl,CommDD and signing problems

[rchik]

Hello there!
The case is, I have a developer certificate with manufacturer granted CommDD and NetworkControl capabilities and still cannot open the dataport on my symbian 9.1 device. Here is a piece of code:

	#ifdef __WINS__
	#define PDD_NAME _L("ECDRV")
	#else
	#define PDD_NAME _L("EUART")
	#endif
	#define LDD_NAME _L("ECOMM")
	
	TInt stepFailed = -1;
	
	TInt r;
		
	r = User::LoadPhysicalDevice (PDD_NAME); // step 1 
	
	if ( ( r != KErrNone ) && ( r != KErrAlreadyExists ) )
 	{
 		stepFailed = 0;
 	}
	
	if( stepFailed == -1 )
	{	
		r =	User::LoadLogicalDevice (LDD_NAME); // step 2 
	
		if ( ( r != KErrNone ) && ( r != KErrAlreadyExists ) )
		{
			stepFailed = 1;
		}
	}
	
	if (stepFailed == -1)
	{	
		r =	StartC32 (); // step 3
	
		if ( r != KErrNone )
		{
			stepFailed = 2;
		}
	}
	
	if ( stepFailed == -1)
	{
		r = server.Connect (); // step 4
	
		if ( r != KErrNone )
		{
			stepFailed = 3;
		}
	}
	
	if ( stepFailed == -1)
	{	
		r = server.LoadCommModule(_L ("DATAPORT")); // step 5
	
		if ( r != KErrNone )
		{
			stepFailed = 4;
		}
	}
	
	if ( stepFailed == -1 )
	{
		r = iComm.Open( server, _L ("DATAPORT::0"), ECommShared);
		
		if ( r != KErrNone )
		{
			stepFailed = 5;
		}
	}
	
	switch ( stepFailed )
	{
		case -1:
		{
			CNotify::Notify(_L("Port opened successfully"));
		}
		break;
		case 0:
		{
			CNotify::ErrorNotify(_L("Failed PDD load"));
		}
		break;
		case 1:
		{
			CNotify::ErrorNotify(_L("Failed LDD load"));
		}
		break;
		case 2:
		{
			CNotify::ErrorNotify(_L("StartC32 failed"));
		}
		break;
		case 3:
		{
			CNotify::ErrorNotify(_L("Connect failed"));
		}
		break;
		case 4:
		{
			CNotify::ErrorNotify(_L("LoadCommModule failed"));
		}
		break;
		case 5:
		{
			CNotify::ErrorNotify(_L("RComm Open failed"));
			
			TBuf<50> message;
			
			message.Format(_L("Error code:%d"), r);
			
			CNotify::Notify(message);
		}
		break;
	}

this code always gives me the last "RComm Open failed" message with error code -46 which means KErrPermissionDenied

Therefore, I have a question - am I doing something wrong or what? I have studied all the stuff in the forums and the only manufacturer granted capabilities that might be needed to open dataport are NetworkControl and CommDD everywhere, maybe I sign the file wrong? I don't know, the Tool7 (VerifySymbianSigned_25_05_2007.exe) says the following about my sis file:

------------------------------
File format : SISX (V9)
SIS file : TestPhoneCallSigned.sis
------------------------------
Symbian Signed : No
Developer Certificate Signed : Yes
ACS Publisher Signed : Yes
ACS Publisher Supplier : Verisign (1 found)
Unknown Certifictaes : 0
------------------------------

as I see, both my ACS and devcerts have managed to sign this file.

PLEASE HELP, I have spent so much time getting those ACS and devcert and still no success

Perhaps you should look in the technical library? Specifically TSS000472

[rchik]

actually, this is the basic document that all my certificate mess was based on, as you see, among advanced capabilities it mentions only NetworkControl and CommDD and my certificate has them, as I have already said, here is the total list of capabilities that my devcert has:

PowerMgmt
ProtServ
SwEvent
NetworkServices
LocalServices
ReadUserData
WriteUserData
Location
SurroundingsDD
UserEnvironment
ReadDeviceData
WriteDeviceData
TrustedUI
CommDD
NetworkControl

[rchik]

did I get it right that all I have to do to activate the capabilities in program is to put the following in the Capability field of the Project->Properties->C/C++ Build->Tool Settings->System Options?

"PowerMgmt ProtServ SwEvent NetworkServices LocalServices ReadUserData WriteUserData Location SurroundingsDD UserEnvironment ReadDeviceData WriteDeviceData TrustedUI CommDD NetworkControl"

I am using Carbide.c++

The case is, I am not getting any capability providing message during the install, only the warning that I am about to install the programm written for development purposes. As well as I don't get any warning message when I launch the app itself, is it normal?
