主题:[原创]vb 编程的一点心得和体会 ,希望会给您带来一点帮助
(1)
消息框中按钮之定义
MsgBox strMsg1, c1+c2+c3 , strMsg2
其中 strMsg1 为提示信息
strMsg2 为标题内容
c1+c2+c3 定义按钮形式,具体如下:
c1: 按钮的类型
0 vbOkOnly 只有一个按钮“确定”
1 vbOkCancel 两个按钮“确定”和“取消”
2 vbAbortRetryIgnore 三个按钮“终止”、“重试”和“忽略”
3 vbYesNoCancel 三个按钮“是”、“否”和“取消”
4 vbYesNo 两个按钮“是”和“否”
5 vbRetryCancel 两个按钮“重试”和“取消”
返回值: vbOk 1 确定
vbCancel 2 取消
vbAbort 3 终止
vbRetry 4 重试
vbIgnore 5 忽略
vbYes 6 是
vbNo 7 否
c2: 图标的类型
16 vbCritical ×
32 vbQuesion ?
48 vbExclamation !
64 vbInformation i
c3: 默认焦点
0 vbDefalaultButton1 左起第一个按钮自动获得焦点
256 vbDefalaultButton2 左起第二个按钮自动获得焦点
512 vbDefalaultButton3 左起第三个按钮自动获得焦点
和为: 00 0000 0000 B
c3 c2 c1
例: 1. i = MsgBox " 是否要删除该条记录 ? ", 1+32+0 , " 请确认"
2. MsgBox " 是否要删除 ! ", 0+32+0 , " 请...."
(2)
判断表的存在
Function M_fucScanTable(strTName As String) As Integer ' 搜索表 strTableName
On Error GoTo OpenErr
Set MyRsm = New Recordset
MyRsm.Open "Select * From " & strTName,Cn, adOpenKeyset, adLockOptimistic
MyRsm.MoveLast
M_fucScanTable = MyRsm.RecordCount ' 返回记录数,0 为空表
MyRsm.Close
Set MyRsm = Nothin
Exit Function
OpenErr:
M_fucScanTable = -1 ' 无表
End Function
(3)
动态建立表
strSQL = "CREATE TABLE " & strTName & _
"( Xh char(3) Not Null Primary key,Mc char(10),Xb char(2)," & _
"Csrq char(10),Zw char(20),Gz numeric(9,2),Bz char(30),Xp image )"
cn.Execute strSQL, , adCmdText
其中: Primary key 为设置主键(唯一)
(4)
插入记录 Insert
strSQL = "Insert Into A01(Xh,Mc,Xb,Csrq,Zw) " & _
"Values ( '" & Xhp & "','" & Mcp & "','" & Xbp &"','" &Rqp& "','" & Zwp & "' "
Cn.Execute strSQL
(5)
导出表格到excel
Dim newxls As Excel.Application
Dim newbook As Excel.Workbook
Dim newsheet As Excel.Worksheet
Set newxls = CreateObject("excel.application")
newxls.Visible = True
Set newbook = newxls.Workbooks.Add
Set newsheet = newbook.Worksheets(1)
For i = 0 To 7
For j = 0 To 4
MSFlexGrid1.Row = i
MSFlexGrid1.col = j
newsheet.Cells(1, 3) = Trim(Combo1.Text) & "班"
newsheet.Cells(1, 4) = "第" & bytXq & "学期"
newsheet.Cells(1, 5) = "课程表"
newsheet.Cells(i + 3, j + 2) = Trim(MSFlexGrid1.TextMatrix(i, j))
Next j
Next i
注意此项操作你先要 引用 excelctl type library 和 microsoft excel 9.0 object library
(6) with 语句的应用
With msflexgrid1
.CellAlignment = 4
.TextMatrix(1, 0) = "考试编号"
.TextMatrix(1, 1) = "学号"
.TextMatrix(1, 2) = "姓名"
.TextMatrix(1, 3) = "班号"
.TextMatrix(1, 4) = "课程名称"
.TextMatrix(1, 5) = "分数"
End With
(7)
响应回车
Private Sub Text2_KeyPress(KeyAscii As Integer) ' Text2 响应回车键
If KeyAscii = 13 Then
Command1.SetFocus
End If
End Sub
(8)
隐藏任务栏
Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, _
ByVal x As Long, ByVal y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
Private Sub Form_Load()
SetWindowPos Me.hwnd, -1, 0, 0, 0, 0, 3
End Sub
希望能给您在编程时带来一点方便
同时我也只是起到一个抛砖引玉的 目的
希望您也能供稿 我方便大家努力
谢谢各位 vb 爱好者们
