kEiAsCii As intEgEr

keyascii as integer 使一些函数的参数,keyascii 是参数名称,as integer是指定参数类型 表示这是一个整形的变量,常见于如下的函数 public sub textbox_keypress(keyascii as integer).end sub keyascii 里是接收到的一个键的ascii码(取值0---255)

dim s as string * 1 表示定义s为1单位长度的字符变量private sub text1_keypress(keyascii as integer)dim s as string * 1, s1 as string * 1, s2 as string * 1 '定义3个变量s = text1.text '你这有误,将text1属性赋值给ss1 = chr(asc(s) - 1) s2 = chr(asc(s) + 1

ASCII码记住常用的就行了,比如回车 13 .ASCII是American Standard Code for Information Interchange的缩写,用来制订计算机中每个符号对应的代码,这也叫做计算机的内码(code).每个ASCII码以1个字节(Byte)储存,从0到数字127代表不同的常用符号,例如大写A的ASCII码是65,小写a则是97.这些是都可以推出来的.

private sub picturel- click() dim asci as integer,i as integer picturel.print" i=0 for asci=32 to 126 picturel.print teb(7*i+2);chr(asci);"=";asci; i= i+1 if i=7 then i=0:picturel.print next asci end sub

1个文本框,1个按钮:Private Sub Command1_Click()Dim Ch As StringDim n As IntegerDim I As IntegerDim d(7) As ByteDim K As IntegerCh = Text1.Textn = Asc(Ch) '将ASCII码的十进制数存入变量n'十进制转换成二进制K = 7Do While K >= 0 d(K) = n Mod 2 n = n \ 2 K = K - 1Loop'显示二进制的各位For I = 1 To 7 Print d(I);Next IEnd Sub

(Key Ascii As Integer) If Key Ascii=13 Then For i=0 TO Comb01.ListCount-1 If Combo1.Text=【 】Then LabelCaption=“输入项已在组合框中” Exit Sub End If Next i LabelCaption=“已成功添加输入项”

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer) Print KeyCodeEnd Sub上38下40左37右39

'这个程序用不着command来做判断 看这个程序 只需添加一个textbox控件即可 private sub text1_keypress(keyascii as integer) if keyascii 57 then keyascii = 0 end sub

假定你Text2中的数字就是用逗号分隔的,那么Dim s() As String, i As Integers = Split(Text2.Text, ",")For i = 0 To UBound(s) s(i) = Val(s(i)) + 1NextOpen "D:\a.txt" For Output As #1Print #1, Join(s, ",");Close #1
