如何实现将vsflexgrid中修改的数据反馈到数据库中

如何实现将vsflexgrid中修改的数据反馈到数据库中？

Private Sub vsflexgrid1_AfterEdit(ByVal Row As Long, ByVal Col As Long)

rs.MoveFirst '//rs为记录集

rs.Move vsflexgrid1.Row - 1

rs.Edit

If vsflexgrid1.text = "" Then

rs.Fields(vsflexgrid1.Col - 1) = Null

Else

rs.Fields(vsflexgrid1.Col - 1) = vsflexgrid1.text

End If

rs.Update

end sub

一、增加记录使用for来循环表格行。

for i=1 to grid1.rows-1

with rs

.addnew

.fileds(o)=grid1.textmariy(i,0)

.fileds(1)=grid1.textmariy(i,1)

.fileds(2)=grid1.textmariy(i,2)

.fileds(3)=grid1.textmariy(i,3)

.update

end with

二、添加行

grid1.additem row

三、删除当前行

with grid1

i=.row

.removeitem i

end with

四、要显示下拉框，可以使用vsflexgrid中列绑定功能

grid1.colcombolist(1)＝grid.buildcombolist(rs,"商品名称")

跟楼上的相比,仅仅是datamode不一样(2-flexDMBoundBatch)

但这样做的优势是非常明显的:可以撤销包括新增删除在内的所有操作,按保存键才写入数据库

Private Sub CmdDel_Click()

If fg.Row <> 0 Then fg.RemoveItem (fg.Row)

fg.Refresh

End Sub

Private Sub CmdAdd_Click()

On Error Resume Next

Adodc1.Recordset.AddNew

If Err.Number <> 0 Then MsgBox Err.Description

End Sub

Private Sub CmdUpdate()

Adodc1.Recordset.UpdateBatch adAffectAllChapters

End Sub

Private Sub CmdCancel_Click()

Adodc1.Recordset.CancelBatch

fg.DataRefresh

End Sub

Private Sub Form_Load()

Adodc1.ConnectionString = "FILE NAME=" & App.Path & "\conn.dsn"

Adodc1.LockType = adLockBatchOptimistic

Adodc1.RecordSource = "Your_Tablename"

Set fg.DataSource = Adodc1

End Sub

1、打印vsflexgrid可以使用vsprinter打印控件。跟vsflexgrid配套使用效果不错。

2、导出EXECL，可以使用grid.savegrid的方法。

用savegrid的方法，在导出execl时，如果碰到类似于银行帐号的列如：“６４６５４５６６６５”，导到ＥＸＥＣＬ中就不这样显示了，这个问题还不知道怎么解决？？

另外也可以写代码（这个方法比较实用，但慢一些）：

Dim excelApp As Excel.Application

Set excelApp = New Excel.Application

On Error Resume Next

If excelApp Is Nothing Then

Set excelApp = CreateObject("Excel.application")

If excelApp Is Nothing Then

Exit Sub

End If

excelApp.Visible = True

Me.MousePointer = vbHourglass

excelApp.Workbooks.Add

With excelApp.ActiveSheet

Dim i As Integer, j As Integer

For i = 1 To Grid1.rows

For j = 1 To Grid1.Cols

.Cells(i, j).value ="'"& Grid1.TextMatrix((i - 1), (j - 1))'加上“'”号则可以解决上面savegrid中银行帐号的导出问题。

Next j

DoEvents

Next i

End With

Me.MousePointer = vbDefault

Set excelApp = Nothing

End Sub

EXCEL同Vsflexgrid通过

最近很多的朋友,都想知道EXCEL怎样同VSflexgrid交换数据。

实际上，利用“复制”、“粘贴”菜单即可实现。具体如下：

（1）在Vsflexgrid上弹出右键菜单

Private Sub grid1_MouseDown(Button As Integer, Shift As Integer, X As Single, y As Single)

if Button = 2 Then PopupMenu mnutccd

End Sub

（2）设置各菜单的内容

A 复制

Clipboard.Clear

Clipboard.SetText grid1.Clip

B 剪切

Dim rowc As Long

Dim rowz As Long

Dim colc As Long

dim colz As Long

dim i as long

dim s as long

If grid1.Rows = 1 Then Exit Sub

Clipboard.Clear

Clipboard.SetText grid1.Clip

If grid1.RowSel > grid1.row Then

rowc = grid1.row

rowz = grid1.RowSel

Else

rowc = grid1.RowSel

rowz = grid1.row

End If

If grid1.ColSel > grid1.Col Then

colc = grid1.Col

colz = grid1.ColSel

Else

colc = grid1.ColSel

colz = grid1.Col

End If

For i = rowc To rowz

For s = colc To colz

grid1.TextMatrix(i, s) = ""

C 粘贴（精华部分)

Dim i As Long

Dim s As Long

Dim m As Long

Dim t As Long

If grid1.Rows = 1 Then Exit Sub

t = Len(Clipboard.GetText)

If t = 0 Then Exit Sub

For i = 1 To t

If Mid(Clipboard.GetText, i, 1) = Chr(9) Then s = s + 1

If Mid(Clipboard.GetText, i, 1) = Chr(13) Then m = m + 1

If s / (m + 1) + grid1.Col > grid1.Cols - 1 Then

grid1.ColSel = grid1.Cols - 1

Else

grid1.ColSel = s / (m + 1) + grid1.Col

End If

If grid1.row + m > grid1.Rows - 1 Then

grid1.RowSel = grid1.Rows - 1

Else

grid1.RowSel = grid1.row + m

End If

grid1.Clip = Clipboard.GetText

几个特殊的属性方法的使用：

FormatString 属性：管道符格式化字符串示例：

下面定义对齐方式同字意，列宽窄同距离

VSG1.FormatString = "^ 中 |< 左 |> 右 |> 右 |^ 中 "

+++++++++++++++++++++++++

搜索(查找)表格中符合条件的行：

FindRow 属性：该属性返回一个行值

MsgBox VSG1.FindRow(关键词,[指定行],[指定列],[敏感],[精度])

关键词：String，表示要搜索的字符串

指定行/指定列：Long，表示只在指定的行或列中找

敏感：Boolean，

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

'限制只能在指定列输入(这里默认倒数第2列)

Private Sub VSG1_BeforeRowColChange(ByVal OldRow As Long, _

ByVal OldCol As Long, ByVal NewRow As Long, _

ByVal NewCol As Long, Cancel As Boolean)

VSG1.Editable = flexEDKbd

If VSG1.Redraw <> flexRDNone And NewCol <> VSG1.Cols - 2 Then

Cancel = True

VSG1.Select NewRow, VSG1.Cols - 2

End If

End Sub

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

限制不能编辑某些列：(这里限制第1列和第3列)

Private Sub VSG1_RowColChange()

If VSG1.Col = 1 Or VSG1.Col = 3 Then

VSG1.FocusRect = flexFocusNone

VSG1.Editable = flexEDNone

'SendKeys "{TAB}"

Else

或：

Private Sub VSG1_RowColChange()

If VSG1.Col = 1 Or VSG1.Col = 3 Then

SendKeys "{RIGHT}"

Else

SendKeys "{ENTER}"

End If

End Sub

或：

Private Sub VSG1_RowColChange()

End If

End Sub

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

'对齐方式(-1标示所有)

.ColAlignment(-1) = flexAlignLeftCenter|flexAlignCenterCenter|flexAlignRightCenter

示例1：(最后一行的第3列靠右对齐)

将数字转换为大写金额的函数：

Function CurrencyToStr(ByVal Number As Currency) As String

Number = Val(Trim(Number))

If Number = 0 Then CurrencyToStr = "": Exit Function

Dim str1Ary As Variant, str2Ary As Variant

str1Ary = Split("零壹贰叁肆伍陆柒捌玖")

flexcpAlignment 对齐方式

flexcpBackColor 背景色

flexcpChecked 选择框

flexcpCustomFormat 格式设置

flexcpData 日期

flexcpFloodColor 颜色

flexcpFloodPercent 背景色

flexcpFont 字体

flexcpFontBold 粗体

flexcpFontItalic 斜体

flexcpFontName 字体名

flexcpFontSize 字体大小

flexcpFontStrikethru 删除线

flexcpFontUnderline 下划线

flexcpFontWidth 字符宽

flexcpForeColor 字符色

flexcpHeight 高

flexcpLeft 左

flexcpPicture 添加图

flexcpPictureAlignment 图对齐

flexcpRefresh 刷新

flexcpSort 分类

flexcpText 字符

flexcpTextDisplay 显示字符

flexcpTextStyle 文本样式

flexcpTop 返回顶端高，同 RowPos 和 valueMatrix 属性

flexcpvalue 返回字符值

flexcpVariantvalue 返回字符值

flexcpWidth 返回单元宽

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

flexSTSum 方法：每行增加小计行[这个方法还不会用]语法：

VSG.flexSTSum 常数名,

[GroupOn As Long], :标签列

[TotalOn As Long], :计算列

[Format As String], :格式，例 "$0.00"

[BackColor As Color], :Color

[ForeColor As Color], :Color

[FontBold As Boolean], :False|True

[Caption As String], :例 "数 %s"

[MatchFrom As Integer], :0|1|2|3

[TatalOnly As Boolean] :False|True

常数名：

常数常数值说明

flexSTNone 0 大纲唯一的，没有合计价值

flexSTClear 1 清除全部的小计

flexSTSum 2 总数

flexSTPercent 3 总数的百分比

flexSTCount 4 行数

flexSTAverage 5 平均

flexSTMax 6 最大的

flexSTMin 7 最小的

flexSTStd 8 标准偏差

flexSTVar 9 方差

1=flexArrow

2=flexCross

3=flexIBeam

4=flexIcon

5=flexSize

6=flexSizeNESW

7=flexSizeNS

8=flexSizeNWSE

9=flexSizeEW

10=flexUpArrow

52=flexSizeHorz '(&H34) '左右调整

53=flexSizeVert '(&H35) '上下调整

54=flexHand '(&H36) 手型

99=flexCustom '自定义

Const MA = "50,51,52,53,54"

Dim xy As Integer

xy = Val(Text1.Text)

If xy > 15 And xy <> 99 And InStr(MA, xy) = 0 Then xy = 15

VSG1.MousePointer = xy

If xy = 99 Then

VSG1.MouseIcon = LoadPicture("C:\icon\Icon.ico")

End If

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

单击列头将列互相拖动调换：

方法一：

VSG1.ExplorerBar = flexExMove '2 这是最简单的方法了

注意这个属性在VB属性表中只设置了0、1、2、3、5、7、8种常数值

ExplorerBar 属性(value=0|1|2|3|5|7|8)：

0-flexExNone：默认，单击列头选择整列，单击行头选择整行

1-flexExSort：单击列头可正反排序该列，单击行头选择整行

2-flexExMove：单击列头可交换列顺序，单击行头选择整行

3-flexExSortAndMove：具有 1 和 2 的功能

4：单击列头可正反排序该列并在列头显示相应箭头，单击行头选择整行

5-flexExSortShow：好像与 4 相同也

6：具有 2 和 4 的功能

7-flexExSortShowAndMove：好像与 6 相同也

8-flexExMoveRows：单击列头选择整列，可拖动行

9：单击列头可正反排序该列，可拖动行

10：可拖动行与列

11：可排序列及拖动行列

12：可排序列并在列头显示相应箭头，还可拖动行

13：同 12。

14：除 12 功能外，可拖动列

15：同 14。

方法二：

Private Sub VSG1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)

Dim r%, c%

r = VSG1.MouseRow

c = VSG1.MouseCol

If r = 0 And c > 0 Then

VSG1.Tag = c

VSG1.Cell(flexcpBackColor, 0, c) = vbYellow

VSG1.MousePointer = flexPointerMove

End If

End Sub

Private Sub VSG1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)

If Len(VSG1.Tag) Then

Dim r%, c%, p%

r = VSG1.MouseRow

c = VSG1.MouseCol

If r = 0 And c > 0 Then p = flexPointerMove

If VSG1.MousePointer <> p Then VSG1.MousePointer = p

End If

End Sub

Private Sub VSG1_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)

If Len(VSG1.Tag) Then

Dim r%, c%, target%

target = VSG1.Tag

VSG1.Cell(flexcpBackColor, 0, target) = 0

VSG1.Tag = ""

VSG1.MousePointer = 0

r = VSG1.MouseRow

c = VSG1.MouseCol

If r = 0 And c > 0 And c <> target Then

VSG1.ColPosition(target) = c
