Post:
now i implemented a application with graphic by using boinc api. and when i run the application with standalone model, the graphic works well. but when i put it on the boinc server and download it as a project, the application works but the graphic does not appear.

my boinc client is run on windows XP. and the server side is the image downloaded form http://boinc.berkeley.edu/dev. i create the project following the quick start tutorial with the command "./make_project --url_base http://a.b.c.d --test_app test". and when i compile the graphic application. i change the application name to uppercase_5.27_windows_intelx86.exe and upload it to the server side.

so can any one tell me what happend? is there anything in the config.xml need to be set? thanks your guys a lot.

Post:
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!

but the question now is how can i put it on the unix server and make the windows client run it. i tried:

http://boinc.berkeley.edu/trac/wiki/QuickStart

but it seems doesn't work. it gives the error report:

10) Message boards : API : does check out have some problem? (Message 21168)
Posted 8 Nov 2008 by lanye
Post:
i checked out the boinc and want to build some application on the windows platform. but when i comile win_build with vc++2005. the BOINCBaseView.cpp file seems have some problem.

there are several hundred of lines look like this:

strEncodedHtml.Replace(wxT("?), wxT("&Scaron;"), true);
strEncodedHtml.Replace(wxT("?), wxT("&OElig;"), true);
strEncodedHtml.Replace(wxT("?), wxT("&lsquo;"), true);

seems that there is a " missed behind the wxT"?) and i compared with the file form the web-based interface, i find the content in " " changed form some thing like Æ to ? and " missed. is this the problem of the check out application or the problem of the system?
i use TortoiseSVN for checking out and my system is windows XP. can any one help me? thanks very much!
