Oh
Divide the decimal by 16 and record the remainder, and do it until the number is 0
Look at the remainders, from last division to first, and that's your hexidecimal
I think, someone told me that one day 
Hold on...

You want a formula or a function?
Well in delphi its IntToHex.
In C# I think its Convert.ToHex ot something... |

All numbers are in hex, you just see it in decimal.
But here is 2 functions to convert a decimal number and hexadecimal:
| Code: |
Function HexToDec(NumberAsString:String):String;
begin
Result:=IntToStr(StrToInt('$'+NumberAsString));
End;
Function DecToHex(NumberAsString:String):String;
begin
Result:=Format('%x',[strtoint(NumberAsString)]);
End; |
usage:
| Code: | procedure TForm1.Button1Click(Sender: TObject);
begin
if Button1.Caption='HexToDec' then
begin
Button1.Caption:='DecToHex';
label1.Caption:=HexToDec(label1.Caption);
end
else
begin
Button1.Caption:='HexToDec';
label1.Caption:=DecToHex(label1.Caption);
end
end; |

VB6 actually has hex commands, I just figured it out now XD
Pretty simple, can't believe it's only 1 line of code
So for a converter, you would need a button and 2 text boxes
So text1 = the decemal, and text2 = the converted hex
| Code: | Private Sub Command1_Click
text2.text = Hex(text1.Text)
End Sub |

Umm, you could try saving the number before, or, try this
Dec(whatever here)
Not sure if it could work though
Nvm it doesn't
Try this for saving
Goes under button click
| Code: | Dim decimal as String
decimal = text1.text
text2.text = Hex(decimal) |
As for converting back, on another button
| Code: | | text1.text = decimal |

Dec() is not a function.
But I did find Oct() but its not for converting hex -> dec... |

Blader I found it on google lol.
| Code: | For y = 1 To Len(Text1.Text)
num = Mid(Text1.Text, y, 2)
Value = Value & Val("&h" & num)
y = y + 1
Next y
Text2.Text = Value |
It works lol. |
