i want to create a boinc application to visit the local OS. such as visit the windows register to get some information and give a MessageBox to the local user.

and i write an application as usual c++ application. the application works well in local machine. but when i put it on the boinc server ( i download the image form the web), the application can be download in the boinc client and executed. but the messagebox do not appear.

i do not know is this the application problem or some options in the config.xml need to be set( i create the app use the uppercase).

can any one tell me ? thanks a lot!

BOINC v6 runs science applications on a separate user account. You can't display anything on the screen.

what does anything mean? if i write some with boinc graphic api, can it be shown on the screen?

actually, there is not any window. so if available, can you tell me how to create such a graphic application by using the example uc2_graphics.cpp form the create project and configuration. i think if the system is avalibale, it should be the problem of the the process i do it.

thanks a lot!

You can't show graphics when you want to. Particularly not a MessageBox.

The uc_graphics stuff you found is for screensaver graphics, to be shown when the user asks for them.
