ios - Change height of cell with change frame of content -


i can make animating of changing row height bad uitableviewrowanimationfade, because it's flickers when animate

- (void)viewdidload {     [super viewdidload];     self.title = @"main vc";     selectedindexes = [nsmutabledictionary new]; }  - (void)willanimaterotationtointerfaceorientation:(uiinterfaceorientation)tointerfaceorientation duration:(nstimeinterval)duration {     [self.tableview reloaddata]; }  - (bool)cellisselected:(nsindexpath *)indexpath {     nsnumber *selectedindex = [selectedindexes objectforkey:indexpath]; return selectedindex == nil ? no : [selectedindex boolvalue]; }  - (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath {     static bool nofirst;     if (!indexpath.row && !nofirst) {         [selectedindexes setobject:@(yes) forkey:indexpath];         nofirst = yes;     }     if ([self cellisselected:indexpath]) {         uiimage *cellimage = helperdf.dataarray[indexpath.row][@"image"];         cgfloat aspectratioindex =  cellimage.size.height / cellimage.size.width;         return [utils screenwidth:self.interfaceorientation] * aspectratioindex;     } else {         return heightcell;     } }

my didselectrowatindexpath

- (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath  *)indexpath {     nsmutableset *insideset = [nsmutableset new];     [insideset addobject:indexpath]; bool isselected = ![self cellisselected:indexpath];     (nsindexpath *keyindexpath in selectedindexes) {         [insideset addobject:keyindexpath];     }     [selectedindexes removeallobjects]; [selectedindexes setobject:@(isselected) forkey:indexpath];     [tableview reloadrowsatindexpaths:insideset.allobjects withrowanimation:uitableviewrowanimationnone]; }

so if use [tableview beginupdates] [tableview endupdates problems change frame of labels , numberoflinew. how can change frames of labels , other parametres, change in cellforrowatindexpath 

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *cellidentifier = @"maincell";     maincell *cell = [tableview dequeuereusablecellwithidentifier:cellidentifier];     nsdictionary *datadictionary = helperdf.dataarray[indexpath.row];     cell.titlelabel.text = datadictionary[@"title"];     cell.descriptionlabel.width = [utils screenwidth:self.interfaceorientation] - 40;     cell.descriptionlabel.text = datadictionary[@"fulltext"];     if ([self cellisselected:indexpath]) {         cell.sequebtn.hidden = no;         cell.pictureview.contentmode = uiviewcontentmodescaletofill;         cell.descriptionlabel.numberoflines = 7;     } else {         cell.sequebtn.hidden = yes;         cell.pictureview.contentmode = uiviewcontentmodescaleaspectfill;         cell.descriptionlabel.numberoflines = 2;     }     [cell.descriptionlabel sizetofit];     cell.pictureview.image = datadictionary[@"image"];     return cell; }   - (void)tableview:(uitableview *)tableview willdisplaycell:(uitableviewcell *)cell forrowatindexpath:(nsindexpath *)indexpath {     maincell *maincell = (maincell *)cell;     maincell.descriptionlabel.originy = maincell.sequebtn.hidden ? heightcell -  maincell.descriptionlabel.height - 5 : maincell.height - maincell.sequebtn.height - maincell.descriptionlabel.height - 12; }

this code used set uitableviewcell height dynamically:

- (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath {    nsdictionary* dict = [branchesarray objectatindex:indexpath.row];    nsstring* address = [nsstring stringwithformat:@"%@,%@\n%@\n%@\n%@",[dict objectforkey:@"locality"],[dict objectforkey:@"city"],[dict objectforkey:@"address"],[dict objectforkey:@"contactnumber"], [dict objectforkey:@"contactemail"]];      cgsize constraint = cgsizemake(220, maxfloat);     cgsize size = [address sizewithfont:[uifont fontwithname:@"helvetica" size:14.0f] constrainedtosize:constraint linebreakmode:nslinebreakbywordwrapping];     cgfloat height1 = max(size.height, 110.0f);    return height1+20; }

as set frame in - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath also

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)...

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...
