Does it happen all the time on some devices but not others or part of the time on any device?  If it happens all the time on some devices check the application permissions by going to Options -> Application Management, select your application and choose Edit Permissions from the menu.  If a required permission has been denied a ControlledAccessException is thrown.

It if happens occasionally on some devices verify the picture you are trying to send.  Third party applications are not able to access the images that come pre-installed on the device (backgrounds, etc...).  If you attempt to access them a ControlledAccessException is thrown.

hi thanks for feedback.

It happens occasionally. but the picture is not pre-installed on the device. is it a platfrom issue?

Could you please give some comments on how to invoke the BB messageconnection.

[RoyWinnie]

Hi MSohm, thanks for feedback. ::

1. It is not our 3rd party application access the images. It is our application initiate the message of BB. And the message accesses the images.
2. And the images are not pre-installed in BB. The images are pictures taken by camera.

Sometimes it can not  attach picture when send mms.

Please verify the application's permission settings.  Where is the code being run from (an ApplicationMenuItem, background listener or from within your application)?

[RoyWinnie]

hi MSohm, The code is run form ApplicationMenuItem.  Any comments?

[MSohm]

The ApplicationMenuItem run method is executed in the process of the application that contains the menu.  If you run from the Messages application, it runs in the Messages process, etc.  This also means that the run method is subject to the application permissions of the application that displays the ApplicationMenuItem.  

You can use the technique used in this example to ensure that you code runs within your own application's process instead.

Allow a background listener to detect and update a GUI application
