c# - Why does DotNetZip cause OutOfMemory Exception in Images? -

-

i have tried zipping .png image file zip file using dotnetzip after extract later on , use image.fromfile method gives me outofmemory exception. have tried other images gives me same result. if override image file wasn't zipped don't error.

compression code

savefiledialog sfd = new savefiledialog(); sfd.filter = system.abriviation + " game|*" + system.extention; sfd.addextension = true; sfd.showdialog();  if (sfd.filename != "") {      streamwriter write = new streamwriter(application.startuppath + "\\meta");     write.writeline(txtname.text);     write.writeline(new fileinfo(txtgame.text).extension);     write.writeline(txtcompany.text);     write.close();      file.copy(txtgame.text, application.startuppath + "\\game" + new fileinfo(txtgame.text).extension);     file.copy(txtgame.text, application.startuppath + "\\icon.png");      zipfile zip = new zipfile();     zip.addfile(application.startuppath + "\\meta", "");     zip.addfile(application.startuppath + "\\game" + new fileinfo(txtgame.text).extension, "");     zip.addfile(application.startuppath + "\\icon.png", "");     zip.save(sfd.filename);     zip.dispose();      file.delete(application.startuppath + "\\game" + new fileinfo(txtgame.text).extension);     file.delete(application.startuppath + "\\icon.png");     file.delete(application.startuppath + "\\meta");      close(); }

extraction code

zipfile zip = zipfile.read(file); bool foundmeta = false; string id = ""; foreach(zipentry e in zip){     if (e.filename == "meta")     {         e.extract(application.startuppath);         streamreader read = new streamreader(application.startuppath + "\\meta");         id = read.readline();         read.close();         file.delete(application.startuppath + "\\meta");         foundmeta = true;         break;     } }  if (foundmeta) {     if (!gamesystem.exists(id))     {         zip.extractall(main.library.path + "\\" + id.replace(" ", "_").tolower());         directory.createdirectory(main.library.path + "\\" + id.replace(" ", "_").tolower() + "\\games");         directory.createdirectory(main.library.path + "\\" + id.replace(" ", "_").tolower() + "\\games\\metas");     }     else     {         messagebox.show("system " + id + " added.", "8 bit", messageboxbuttons.ok, messageboxicon.error);     } } else {     messagebox.show("could not find meta file.", "8 bit", messageboxbuttons.ok, messageboxicon.error); } zip.dispose();  return gamesystem.load(main.library.path + "\\" + id.replace(" ", "_").tolower());

image loading code

string name = "", company = "", ext = ""; fileinfo info = new fileinfo(file); streamreader read = new streamreader(file); name = read.readline(); ext = read.readline(); company = read.readline(); read.close();  image icon = null; if (file.exists(system.gamemetapath + "\\" + info.name + ".png")) {     icon = image.fromfile(system.gamemetapath + "\\" + info.name + ".png");     //the error happens on line above. }  return new game(system, name, company, system.gamepath + "\\" + info.name + ext, file, icon);

is there way around or fix problem?

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution: ...

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
