i looking using custom build tool files of project. since command line similar of files , lazy type out entire command every time every file needs it, thought i'd create usermacro contains command line , every file needs custom build tool type $(mytool) command line. it works in vs calls process, macro defined using vs internal variables such %(fullpath) , %(filename) . unfortunately, though ui macro preview shows these variables are, appears they're being replaced once (at time visual studio parses macro?) rather every time macro used. usermacro: sometool.exe "%(fullpath)" -outputfile "$(projectdir)generated\%(filename).cpp" called: sometool.exe \path\to\project\generated\(filename).cpp looks if specified get's stripped away, command line missing drive letter , colon $(projectdir) weird reason. specifying macro content command line in file properties custom build tool working expected, that's lot of typing every file (and every new ...

i have form model indicators represented checkboxes. model value true/false in form object json. value convert boolean number, 1/0 respectively. there smart way this? example code: @component template: ` <form [formgroup]="myform" (ngsubmit)="save(myform.value)"> <input type="checkbox" id="mytoggle" formcontrolname="mytoggle"/> </form> ` export class mycomponent implementes oninit{ private myform:formgroup; mytoggle: number; constructor(private _fb:formbuilder) {} ngoninit() { this.myform = this._fb.group({ mytoggle: [0] }); } hopefully above demonstrating i'm trying set type of "mytoggle" number. initializing form setting default 0 , correctly leaving checkbox unchecked. however, updating checkbox checked set form value true instead of 1. want updated 1. via this question see there options converting booleans numbers. however, i'm unsure of how i...
