Guys, how can i add reg values in regedit from Decimal to Hexadecimal automatically? (in bath file)

Question

So, i have a code

reg add "bla bla bla" /v "bla bla bla" /t REG_DWORD /d "%problem%" /f >nul 2>&1 , btw %problem% is decimal number

so i need "%problem%" to be Hexadecimal value in decimal system, i tried reg add "bla bla bla" /v "bla bla bla" /t REG_DWORD /h "%problem%" /f >nul 2>&1 (instead /d i tried /h)

but its doesnt work, so how can i put my decima-system value in Hexadecimal cell?]

and i know that my knowledge of bat files is flawed...

Answer 1

btw %problem% is decimal number

Then just use it as is. If it's a hex value, then it has to start with "0x".

reg add hkcu\software /v TestValue /d 0xffff /t REG_DWORD /f  
reg query hkcu\software /v TestValue   
reg add hkcu\software /v TestValue /d 16 /t REG_DWORD /f   
reg query hkcu\software /v TestValue   
  

set problem=ffff  
reg add hkcu\software /v TestValue /d 0x%problem% /t REG_DWORD /f  
reg query hkcu\software /v TestValue   
set problem=16  
reg add hkcu\software /v TestValue /d %problem% /t REG_DWORD /f   
reg query hkcu\software /v TestValue
