-

hi im trying save image sdcard , im having problem using media scanner scan new saved file available

the errors in following lines 

new string[] { file.tostring() }, null, // error: file cannot resolved  new mediascannerconnection.onscancompletedlistener() {  // error: mediascannerconnection.onscancompletedlistener cannot resolved type

this code:

public void savetosdcard(bitmap bitmap, string name) {         boolean mexternalstorageavailable = false;         boolean mexternalstoragewriteable = false;         string state = environment.getexternalstoragestate();         if (environment.media_mounted.equals(state)) {             mexternalstorageavailable = mexternalstoragewriteable = true;             log.v(tag, "sd card available read , write "                     + mexternalstorageavailable + mexternalstoragewriteable);             savefile(bitmap, name);         } else if (environment.media_mounted_read_only.equals(state)) {             mexternalstorageavailable = true;             mexternalstoragewriteable = false;             log.v(tag, "sd card available read "                     + mexternalstorageavailable);         } else {             mexternalstorageavailable = mexternalstoragewriteable = false;             log.v(tag, "please insert sd card save ad "                     + mexternalstorageavailable + mexternalstoragewriteable);         }     }      private void savefile(bitmap bitmap, string name) {          string filename = name;         contentvalues values = new contentvalues();         file sdimagemaindirectory = new file(environment                 .getexternalstoragedirectory(), getresources().getstring(                 r.string.directory));         sdimagemaindirectory.mkdirs();         file outputfile = new file(sdimagemaindirectory, filename);         values.put(mediastore.mediacolumns.data, outputfile.tostring());         values.put(mediastore.mediacolumns.title, filename);         values.put(mediastore.mediacolumns.date_added, system                 .currenttimemillis());         values.put(mediastore.mediacolumns.mime_type, "image/png");         uri uri = this.getcontentresolver().insert(                 android.provider.mediastore.images.media.external_content_uri,                  values);         try {             outputstream outstream = this.getcontentresolver()                     .openoutputstream(uri);             bitmap.compress(bitmap.compressformat.png, 95, outstream);              outstream.flush();             outstream.close();         // im having problem           // tell media scanner new file             // available user.             mediascannerconnection.scanfile(this,                     new string[] { file.tostring() }, null,                     new mediascannerconnection.onscancompletedlistener() {                 public void onscancompleted(string path, uri uri) {                     log.v("externalstorage", "scanned " + path + ":");                     log.v("externalstorage", "-> uri=" + uri);                 }             });         } catch (ioexception e) {             // unable create file, because external storage             // not mounted.             log.v("externalstorage", "error writing " + file, e);         }     }

i got working nicely static method scanfile

and here code:

string filepath = environment.getexternalstoragepublicdirectory(environment.directory_pictures).getabsolutepath() + "/" + filename;     mediascannerconnection.scanfile(this, new string[] { filepath }, null, null);

hope helps...

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
