ios - Getting OauthException when uploading a video to facebook -


i trying upload video on iphone user's facebook timeline using social framework. used snippet given in this answer. here code:

- (void)performactivity { nslog(@"sharing on facebook.");  acaccountstore *accountstore = [[acaccountstore alloc] init];  acaccounttype *facebookaccounttype = [accountstore accounttypewithaccounttypeidentifier:acaccounttypeidentifierfacebook];  nsdictionary *options = @{acfacebookappidkey : @"***", acfacebookpermissionskey : @[@"email"], acfacebookaudiencekey:acfacebookaudiencefriends};  [accountstore requestaccesstoaccountswithtype:facebookaccounttype options:options completion:^(bool granted, nserror *error) {     if (granted) {          nsdictionary *options = @{acfacebookappidkey : @"***", acfacebookpermissionskey : @[@"publish_stream"], acfacebookaudiencekey:acfacebookaudiencefriends};          [accountstore requestaccesstoaccountswithtype:facebookaccounttype options:options completion:^(bool granted, nserror *error) {             if (granted) {                 nslog(@"publishing");                 acaccount *fbaccount = [accountstore accountswithaccounttype:facebookaccounttype][0];                  nsurl *videourl = [nsurl urlwithstring:@"https://graph.facebook.com/me/videos"];                  nsurl *pathurl = [nsurl fileurlwithpath:[nsstring stringwithformat:@"%@session.mov", nstemporarydirectory()]];                 nsdata *videodata = [nsdata datawithcontentsoffile:[nsstring stringwithformat:@"%@session.mov", nstemporarydirectory()]];                 nsdictionary *params = @{                                          @"title": @"nebuu",                                          @"description": @"mebuu"                                          };                  slrequest *uploadrequest = [slrequest requestforservicetype:slservicetypefacebook                                                               requestmethod:slrequestmethodpost                                                                         url:videourl                                                                  parameters:params];                 [uploadrequest addmultipartdata:videodata                                        withname:@"source"                                            type:@"video/quicktime"                                        filename:@"nebuu video"];                  uploadrequest.account = fbaccount;                  [uploadrequest performrequestwithhandler:^(nsdata *responsedata, nshttpurlresponse *urlresponse, nserror *error) {                     nsstring *responsestring = [[nsstring alloc] initwithdata:responsedata encoding:nsutf8stringencoding];                     if(error){                         nslog(@"error %@", error.localizeddescription);                     }else                         nslog(@"%@", responsestring);                 }];             }}];     }}]; }

as can see, first requested read permission(email) then, requested publish permission if first request granted. code works fine, permissions granted , app begins uploading video(i can see in network monitoring tool). however, after video uploaded error:

{   "error": {     "message": "an unexpected error has occurred. please retry request later.",     "type": "oauthexception"   } }

what might problem here? read other posts , seems possible thet error originated facebook's side. suggestions?

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
