objective c - how to temporarily hide the main menu (NSMenu)? -


i'm trying implement feature password protect cocoa app. in appdelegate, if password entered correctly on window, i'll bring main app window calling nsapp runmodelforwindow method.

it works fine, except, in preferences allow user change password. means in order prevent hacking users, i'll have hide main menu, until password entered correctly.

i don't want remove menu items using removeitematindex or programmatically set target action call method bring preference window. instead, temporary hide [nsapp mainmenu]. searched , can't seem find method, sethidden:yes in order hide it.

i have tried [[nsapp mainmenu] canceltracking] doesn't job

is there easy way this?

you can use -setpresentationoptions: method on nsapp hide , show many parts of standard os ui, including menu bar , dock. note must hide both menu bar , dock together:

/* hide */ [nsapp setpresentationoptions:[nsapp presentationoptions] |                                nsapplicationpresentationhidemenubar |                                nsapplicationpresentationhidedock];  /* show */ [nsapp setpresentationoptions:[nsapp presentationoptions] ^                                nsapplicationpresentationhidemenubar ^                                 nsapplicationpresentationhidedock];

this pretty disruptive ui experience though. consider disabling menu items or ui elements don't want user access while password dialog on screen.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
