Comparison mobile devices as dev. platforms iPhone, Blackberry Windows Mobile -

-

i trying compare 3 above mentioned platforms , considerations 1 needs think when programming in order create kind of code base run on three.

this have collected iphone - great if else write similar other two.

  1. only 1 application can run @ given time. i.e. why sqllite database loaded file app instead of traditionally having kind of server connect to.
  2. only 1 fixed size window 480x320 pixels
  3. runs in sandbox, when app deployed sandbox created "around" app, app can read/write files within area. low-level access phone restricted.
  4. since program can stopped @ time (see point 1) needs considered when designing app, @ time must app able write current state disk can resume later. if takes longer 5 seconds app aborted.
  5. 128mb ram, half of 64mb available app. there typicall 4gb storage (depends on model), no virtual memory, if memory running out app may aborted.

edit: clear, not after platform/os best developer, interested in spec. comparison know can expected if 1 has 3 target platforms , using native language each (not web apps), memory , other considerations are.

edit: removed language assumed native language platform used.

for windows mobile want add:

  • windows mobile in comparison iphone allows multiple applications run @ same time.
  • it comes variable screen sizes , has different sdks ( windows mobile professional 'windows phones' (smartphones) touchscreens , windows mobile standard 'windows phones' regular screens)
  • the framework used .net compact framework besides people prefer open-net open source framework.
  • unlike in iphone, windows mobile has no private api's means gives more power developers.
  • the memory size allowed program 32 mb
  • you not need developer license developing , shipping applications on windows mobile although windows mobile prompts avoid installing apllications unknown publishers.( more interesting unlike in iphone need have license while want debug applcation on device(not jailbroken devices.))

and bad things windows mobile, see link.

thanks,

madhup

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() . (i.e. if executes app command prompt write console.) the problem if create windows form (or wpf) application can have there no taskbar, console or window show up, console.writeline() nothing. if create console app, writes console, can't figure out how hide (and if did hide it, write command prompt window?)... how do this? just create standard console application. callers responsibility hide window caused program (from how run c# console application console hidden ): system.diagnostics.processstartinfo start = new system.diagnostics.processstartinfo(); start.filename = dir + @"\myprocesstostart.exe"; start.windowstyle = system.diagnostics.processwindowstyle.hidden;

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...
