powershell - How to specify data type for hashtable? -


it seems powershell hashtable (@{}) map of string→string default. wish value type int32 calculation on it.

how specify type information when declaring hashtable variable?

hashtables map keys values. type of keys , values immaterial.

ps c:\> $ht = @{} ps c:\> $ht[1] = 'foo' ps c:\> $ht['2'] = 42 ps c:\> $ht  name                           value ----                           ----- 2                              42 1                              foo  ps c:\> $fmt = "{0} [{1}]`t-> {2} [{3}]" ps c:\> $ht.keys | % {$fmt -f $_, $_.gettype().name, $ht[$_], $ht[$_].gettype().name} 2 [string]      -> 42 [int32] 1 [int32]       -> foo [string]

if have integer in string , want assign integer, can cast on assignment:

ps c:\> $ht[3] = [int]'23' ps c:\> $ht.keys | % {$fmt -f $_, $_.gettype().name, $ht[$_], $ht[$_].gettype().name} 2 [string]      -> 42 [int32] 3 [int32]       -> 23 [int32] 1 [int32]       -> foo [string]

powershell Start-Process exit code -1073741502 when used with Credential from a windows service environment -

i'm running strange behavior powershell start-process call. here call: $process = start-process ` "c:\somepath\mybinary.exe" ` -passthru ` -credential $defaultcredential ` -wait ` -workingdirectory "c:\somepath" ` -loaduserprofile if ($process.exitcode -ne 0) { #do } this call return exit code - 1073741502 . after quick search, exit code seems related generic error when program not load required dll (aka. status_dll_init_failed ). when run without -credential $credential program runs correctly. in order isolate problem, manually launched some.exe in prompt target credential , runs smoothly. so problem seems come way start-process cmdlet launch process. i found potential solutions problem tried apply no luck : link , link . would have idea of what's going on here ? edit 1: run proc mon monitoring program activities when launched directly or via powershell script. problem seems occur when loading kernelbase
