forms - Get value back from a text box class -


we have script written no longer us. new powershell , function not returning value:

# prompt user ip/dns address input. function get-ip { [void] [system.reflection.assembly]::loadwithpartialname("system.drawing")  [void] [system.reflection.assembly]::loadwithpartialname("system.windows.forms")   # creates message box accepts dns/ip address input. $objform = new-object system.windows.forms.form $objform.text = "user input required" $objform.size = new-object system.drawing.size(300,200)  $objform.startposition = "centerscreen"  $objform.keypreview = $true $objform.add_keydown({if ($_.keycode -eq "enter")      {$x=$objtextbox.text;$objform.close()}}) $objform.add_keydown({if ($_.keycode -eq "escape")      {$objform.close()}})  $okbutton = new-object system.windows.forms.button $okbutton.location = new-object system.drawing.size(75,120) $okbutton.size = new-object system.drawing.size(75,23) $okbutton.text = "ok" $okbutton.add_click({$x=$objtextbox.text;$objform.close()}) $objform.controls.add($okbutton)  $cancelbutton = new-object system.windows.forms.button $cancelbutton.location = new-object system.drawing.size(150,120) $cancelbutton.size = new-object system.drawing.size(75,23) $cancelbutton.text = "cancel" $cancelbutton.add_click({$objform.close()}) $objform.controls.add($cancelbutton)  $objlabel = new-object system.windows.forms.label $objlabel.location = new-object system.drawing.size(10,20)  $objlabel.size = new-object system.drawing.size(280,40)  $objlabel.text = "please enter ip address of server want connect to:" $objform.controls.add($objlabel)   $objtextbox = new-object system.windows.forms.textbox  $objtextbox.location = new-object system.drawing.size(10,70)  $objtextbox.size = new-object system.drawing.size(260,20)  $objform.controls.add($objtextbox)   $objform.topmost = $true  $objform.add_shown({$objform.activate()}) [void] $objform.showdialog() }

i'm calling such:

$ip = get-ip

i enter in value , i'm not getting in $ip.

how capture value of text box?

for martin

i made changes martin suggested , here new code:

# prompt user ip/dns address input. function get-ip { [void] [system.reflection.assembly]::loadwithpartialname("system.drawing")  [void] [system.reflection.assembly]::loadwithpartialname("system.windows.forms")   # creates message box accepts dns/ip address input. $objform = new-object system.windows.forms.form $objform.text = "user input required" $objform.size = new-object system.drawing.size(300,200)  $objform.startposition = "centerscreen"  $objform.keypreview = $true $objform.add_keydown({if ($_.keycode -eq "enter")      {$script:x=$objtextbox.text;$objform.close()}}) $objform.add_keydown({if ($_.keycode -eq "escape")      {$objform.close()}})  $okbutton = new-object system.windows.forms.button $okbutton.location = new-object system.drawing.size(75,120) $okbutton.size = new-object system.drawing.size(75,23) $okbutton.text = "ok" $okbutton.add_click({$script:x=$objtextbox.text;$objform.close()}) $objform.controls.add($okbutton)  $cancelbutton = new-object system.windows.forms.button $cancelbutton.location = new-object system.drawing.size(150,120) $cancelbutton.size = new-object system.drawing.size(75,23) $cancelbutton.text = "cancel" $cancelbutton.add_click({$objform.close()}) $objform.controls.add($cancelbutton)  $objlabel = new-object system.windows.forms.label $objlabel.location = new-object system.drawing.size(10,20)  $objlabel.size = new-object system.drawing.size(280,40)  $objlabel.text = "please enter ip address of server want connect to:" $objform.controls.add($objlabel)   $objtextbox = new-object system.windows.forms.textbox  $objtextbox.location = new-object system.drawing.size(10,70)  $objtextbox.size = new-object system.drawing.size(260,20)  $objform.controls.add($objtextbox)   $objform.topmost = $true  $objform.add_shown({$objform.activate()}) [void] $objform.showdialog() $x }

i same error message before:

ps e:\dropbox\powershell scripts\sss cloud icons> .\cloudicons.ps1 creating directories... mkdir : cannot bind argument parameter 'path' because empty string. @ e:\dropbox\powershell scripts\sss cloud icons\cloudicons.ps1:80 char:4 + md $_.username +    ~~~~~~~~~~~     + categoryinfo          : invaliddata: (:) [mkdir], parameterbindingvalidationexception     + fullyqualifiederrorid : parameterargumentvalidationerroremptystringnotallowed,mkdir

did miss something?

** update **

i asked how calling get-ip:

# insert user entered ip pipeline. $ip = get-ip # sets user entered ip new file called propanehasip.rdp. (get-content .\propanetest.rdp) -replace 'full address:s:insertiphere',"full address:s:$ip" | out-file propanehasip.rdp  write-host "creating directories..." import-csv $csv | foreach-object {  # creates directories based on username field. md $_.username # creates icons based on propanehasip.rdp , wsid fields. (get-content ".\propanehasip.rdp") -replace 'remoteapplicationcmdline:s:insertwsidhere',"remoteapplicationcmdline:s:$($_.wsid1)" | out-file ".\$($_.username)\propane $($_.wsid1).rdp" (get-content ".\propanehasip.rdp") -replace 'remoteapplicationcmdline:s:insertwsidhere',"remoteapplicationcmdline:s:$($_.wsid2)" | out-file ".\$($_.username)\propane $($_.wsid2).rdp" } }

update #2

i figured out how debug in visual studio. error happening on line:

(get-content .\propanetest.rdp) -replace 'full address:s:insertiphere',"full address:s:$ip" | out-file propanehasip_new.rdp

$x valid inside block (the scope of variable $x), if change $script:x , add $x before ending } of function, works. additional $x needed represent return value of function.

changes:

$objform.keypreview = $true $objform.add_keydown({if ($_.keycode -eq "enter")      {$script:x=$objtextbox.text;$objform.close()}}) $objform.add_keydown({if ($_.keycode -eq "escape")      {$objform.close()}})  $okbutton = new-object system.windows.forms.button $okbutton.location = new-object system.drawing.size(75,120) $okbutton.size = new-object system.drawing.size(75,23) $okbutton.text = "ok" $okbutton.add_click({$script:x=$objtextbox.text;$objform.close()}) $objform.controls.add($okbutton)

end of function:

$objform.add_shown({$objform.activate()}) [void] $objform.showdialog() $x }

and... script taken here , should demonstrate use of windows.forms. however, didnt found date, when posted.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
