command line - Batch File Adding Space to Variable - 


@echo off  cls  rem start backup title backup  setlocal enabledelayedexpansion  rem capture date/time(right down second) , assign variable set yy=%date:~-4% set dd=%date:~-7,2% set mm=%date:~-10,2% set newdate=%dd%%mm%%yy%_%time:~0,8% set newdate=%newdate::=% set foldername=svetlana_backup_%newdate%  rem variables set drive=r: set sevenzip=%userprofile%\7z.exe  set destination=r:\backup  echo running backup batch file  echo please plug in %drive% pause  echo %foldername%  mkdir %destination%\%foldername%  /f "tokens=1,2 delims=," %%i in (backuplist.txt) (      set completesource=%%i     set completedestination=%destination%\%foldername%\%%j      echo source: "!completesource:"=!"     echo destination:"!completedestination:"=!"      mkdir "!completedestination:"=!"     xcopy "!completesource:"=!" "!completedestination:"=!" /e /f )  rem zip folder using 7z command line utility %sevenzip% -tzip %destination%\%foldername%.zip %destination%\%foldername%  rem remove unzipped backup folder rmdir /q /s %destination%\%foldername%  pause exit

this backup batch file i've been using last couple of days. worked until morning. reason, when creates variable foldername, contains space in string there none before. ends this:

svetlana_backup_22092016_ 93829

the space between dash , 93829 never there before until today reason. how remove , prevent happening again?

you can parse file-/foldername this
set foldername=%foldername: =%

this replace spaces empty string

the problem caused because test run @ time hour contained 1 digit. %time:~0,8% output time including space, time stored this: 9:38:29 7 characters , read last 8 ones.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
