KErrPermissionDenied and Keylistener

[gemilib]

Hi
when my app executes the following istruction

TRAP(errorCode,User::LeaveIfError( iCaptureHandle = iWindowGroup->CaptureKey( KKeyCode0 , 0, 0 )));

it exits with the following code:
errorCode=-46

(KErrPermissionDenied = -46 An operation cannot be performed due to a potential security violation.)

I have added SwEvent Capability in the mmp file.

the code is at the following link

Could you help me ,please?

You should not have multiple CAPABILITY lines in the .mmp, since only the first one will be taken into account.

Could I have in .mmp file one line like this?


CAPABILITY ReadUserData SwEvent

You should not have multiple CAPABILITY lines in the .mmp, since only the first one will be taken into account.

you are right gemilib line is very important if you did not mention this in your mmp file by default the capability is none and for key handling you need SwEvent capability.

for more detail about mmp file look "mmp File" in sdk.
