實現步驟

步驟一：建立視窗，並設計視窗畫面

步驟二：按鈕 “十進位制==>二進位制”事件

Dec=Trim(文字框0.Text)

D2B = ""
Do While Dec > 0
D2B = Dec Mod 2 & D2B
Dec = Dec \ 2
Loop
lblerjinzhi.Text=D2B

步驟三：按鈕“十進位制==>十六進位制”事件

Dec=Trim(文字框0.Text)

Dim a
D2H = ""
Do While Dec > 0
a = CStr(Dec Mod 16)
Select Case a
    Case "10": a = "A"
    Case "11": a = "B"
    Case "12": a = "C"
    Case "13": a = "D"

    Case "15": a = "F"
End Select
D2H = a & D2H
Dec = Dec \ 16
Loop
lblshiliujinzhi.Text=D2H
 

步驟四：按鈕“十六進位制==>十進位制”事件
