我在sql server 2000中有这个查询:
select pwdencrypt('AAAA')
Run Code Online (Sandbox Code Playgroud)
它输出加密的'AAAA'字符串:
0x0100CF465B7B12625EF019E157120D58DD46569AC7BF4118455D12625EF019E157120D58DD46569AC7BF4118455D
如何从其原点(即'AAAA')转换(解密)输出?
我如何在VB.NET中编写以下算法?
Procedure logfile()
{
if "C:\textfile.txt"=exist then
open the textfile;
else
create the textfile;
end if
go to the end of the textfile;
write new line in the textfile;
save;
close;
}
