windows - 如何要求用户激活我的程序？

Question

我想知道...

我有一个程序，我想为此收费。

它在 Windows 上运行，主要用 VB 和批处理文件编写...

如何强制用户为其购买产品密钥，并激活它以使用付费版本？

提前致谢！

这只是一个小例子，向您展示您可以限制程序的执行次数，因此如果达到最大执行次数，程序将自行自动删除

@echo off
Setlocal enabledelayedexpansion
Title Count the number of times my BATCH file is run
Mode Con Cols=70 lines=7 & color 0E
Set /a MaxExecution=3
set /a count=1
set "FileCount=%tmp%\%~n0.dll"
If Not exist "%FileCount%" (
    echo !count! > "%FileCount%"
) else (
    For /F "delims= " %%a in ('Type "%FileCount%"') Do (
        set /a count=!count! + %%a
        echo !count! > "%FileCount%"
    )
)
echo.
echo             This Program is running for "!count!" time(s)
Call :SelfDelete
