c# - Programatically start a process independent of platform -


situation

i trying run command-line tool, dism.exe, programmatically. when run manually works, when try spawn following:

var systempath = environment.getfolderpath(environment.specialfolder.system);  var dism = new process(); dism.startinfo.filename = path.combine(systempath, "dism.exe"); dism.startinfo.arguments = "/online /get-features /format:table"; dism.startinfo.verb = "runas"; dism.startinfo.useshellexecute = false; dism.startinfo.redirectstandardoutput = true;  dism.start(); var result = dism.standardoutput.readtoend(); dism.waitforexit();

then result comes out as:

error: 11

you cannot service running 64-bit operating system 32-bit version of dism. please use version of dism corresponds computer's architecture.

problem

i'm aware of causes this: project set compile x86 platform. (see this question example, although none of answers mention this). however, unfortunately requirement @ moment continue targeting platform, not able fix switching cpu.

so question how programmatically spawn process in way independent of platform of parent- i.e. keep project targeting x86, start process target correct platform machine on.

even though i'm running correct dsim.exe in system32

but you're not. that's point. the file system redirector lies 32-bit processes , when ask system32 x86 process, file syswow64. if want access 64-bit exe, need ask via %windir%\sysnative

(%windir% being specialfolder.windows)

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.
