suppose have 2 fragments , b. has 2 integer variables named data_1=2 , data_2=3. transaction fragment -> fragment b . note fragment b needs data_1 doesn't need data_2, so, send variable data_1 through bundle. so, when transaction fragment b -> fragment a , sending modified value of data_1, use new value of data_1 original value of data_2 = 3 retained ? if not, how retain value? there various ways of doing it, easiest way in opinion share data parent activity. basically so: class mainactivity extends activity { public static int data_1 = 1, data_2 = 2; //all other code goes here } then in child fragment set data go: mainactivity.data_1 = 5; whereas read data call static value. int current_data = mainactivity.data_1; if need instances of activity whatever reason can set getter , setter functions instance's (not static) variable.

i've had crash report, it's real edge case. launch pin security view applicationwillenterforeground (the feature optional). however, have form sheets use in situations in app. so pin view added subview on window , keypad presented. when form sheet showing, appears on top of pin view (which wrong) , action on form sheet causes crash, when showing keypad. so believe need dismiss form sheets if application resigns / becomes active. i've looked sending notification form sheet in applicationwillenterforeground , i'll have firstly determine if form sheet visible add method dismiss every form sheet. this seems lot of work edge case, can suggest alternative approach? for completeness here's error... the layout constraints still need update after sending -updateconstraints <_uikeyboardlayoutalignmentview: 0x14e59b790; frame = (0 0; 0 0); userinteractionenabled = no; layer = >. _uikeyboardlayoutalignmentview or 1 of superclasses may have overridden...

i'm writing c++ program has run administrator. gather way arrange add note effect manifest file linked executable. how do this? in c# can create manifest add new item, doesn't seem apply c++. project properties/linker has section on manifests, seems discuss automatically generating manifest each time program compiled, rather generating manifest once can edited. however, though generate manifest has value of yes, no manifest file appears in project directory tree after build. what missing? project -> properties linker -> manifest file uac execution level : requireadministrator note: manifest embedded exe file itself, resource. don't need edit it.

is there way add attribute method without modifying class file? e.g. i'm importing wsdl generates reference.cs containing proxy class methods. i have written attribute work me , adding method below, , works fine: reference.cs file public partial class whatever { [mycustomattrubute()] public void mymethod(string bleh) { // stuff return; } } however, problem if wsdl changes need update it, automatically lose changes reference.cs. can add attribute method file? if other method string, can not concatenate other method this? in other words when call mymethod(string bleh), pass 2 strings concatenated it. for example: mymethod(string1 + "|" + string2); this pass 2 parameters concatenated pipe, in method can use string[] vals = val.split('|'); which give array of parameters passed. way pass more 2 parameters through. then parameters as: sting para1 = vals[0]; sting para2 = vals[1];
