c# - Intermittent ArgumentOutOfRangeException when using AlternativeFrame -


i'm using winrtxamltoolkit's alternativeframe in xamrin/mvvmcross windows 8.1 application support animations while doing page navigations. animations run fine first couple of transitions, intermittently application unhandledexception mid-animation --

the operation attempted access data outside valid range (exception hresult: 0x8000000b)"

system.argumentoutofrangeexception: collection cannot work indices larger int32.maxvalue - 1 (0x7fffffff - 1). parameter name: index @ system.runtime.interopservices.windowsruntime.listtobindablevectoradapter.ensureindexint32(uint32 index, int32 listcapacity) @ system.runtime.interopservices.windowsruntime.listtobindablevectoradapter.getat(uint32 index)

that's stack trace. same animation works several times throw error on future attempt. have ideas causing or ideas on how more information?

the offending views unnecessarily ui heavy -- gridviews inside listviews when simple itemscontrols have sufficed. replaced them , exception went away.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
