采用VB发送接收ascii码!我的接收怎么是乱码?
VB code:
Private Sub com_init()
With MSComm1
.CommPort = 1 'COM1
.Settings = "9600, E, 7, 1"
.InputMode = comInputModeBinary
.InputLen = 14
......
如题,我代码如下
Dim a As Long
Dim b As Long
a = &H5
b = &H31
List1.AddItem a Xor b
输出结果为52
可是正确结果应为34,我是那个地方出错了呢?请大侠帮忙
List1.AddItem hex(a Xor b)
谢谢!
......
"insert into user1(name,age) values('" & Text1.Text & "','" & Text2.Text & "' )"
问题:对sql语句中单、双引号模糊。既然 Text1.Text就表示字符串了,为啥还要 & 和 "呢?不是多此一举么?
"insert into user1(name,age) values(& ......
在VB,
dim a as long
怎么对 a 进行右移位 24?
怎么对 a 进行右移位 16?
怎么对 a 进行右移位 8?
怎么对 a 进行右移位 0?
VB程序中实现字节移位操作
VB code:
'2.逻辑右移
Public Function SHR(OPR As Byte, n As Integer) As Byte
Dim BD As Byte
Dim I As Integer
BD = OPR
For i = ......

字符串原来格式如下:
