发帖数: 177 | 1 现有用PB5做的若干PBL，在主PBL中有连接数据库的代码，可是在PB
中与数据库的连接必须是明码写在PB的脚本中的，若不编释，则可通
过单步跟踪获得数据库的用户名和口令，很不安全。
请问在不对所有PBL编释的情况下，可有解决方法可使通过单步跟踪
无法获得数据库的用户名和口令。
如果可对主PBL进行单独编释，请详细说明如何单独编释。
多谢！ |

发帖数: 808 | 2 I want to read or write a binary file in pb5.
But the functions,such as FileRead,FileWrite are
work in ASCII.So i want to use API functions.
OpenFile or CreateFile
ReadFile or ReadFileEx
WriteFile or WriteFileEx
CloseHandle
Can you tell how to declare these extern functions
in pb? |

The purpose of this assignment is to give you more experience using the AVR
ports, and to add some I/O devices that might become useful later for our
RTOS.
You are to use one of the provided keypads to implement a “digital lock.”
Your program should allow the user to enter a four digit code from the
keypad, and if the code that is input matches the one included in your
program, the “lock” should open. In this case, the lock opening will be
represented by the lighting of an LED.

发帖数: 10 | 7 在Delphi4中定义了一个函数
function MyFun(h1,h2:PChar):WORD;
用Delphi编写的程序调试生成的DLL,一切正常。
但在PB中
用 FUNCTION int MyFun(string h1, string h2) LIBRARY "fundll.dll"申明后
执行，却出现无效页错误，被迫退出, 这是怎么回事 |

发帖数: 29 | 10 I just want to do a simple QBE.
1)querymode=yes
2)acceptTex
3)retrieve
4)querymode=no
The problem is no matter what I input in query mode, I always get all records
in table (query creteria dosn't work!)
I checked the sqlsyntax in sqlpreview even, there is no "where" at all.
I am working on PB9. So anybody can give me some suggestion? Thanks!
Actually I used PB5 PB6 for 2+ years several years ago. I am really mad that
I can't even do the simle QBE right now!
Please help! Thanks! |
