增加 MsFlexGrid 的編輯功能
概述
MsFlexGrid 控件沒有提供文本編輯的功能，下面的例子演示了如何利用一個(gè)TextBox 實(shí)現(xiàn)編輯當(dāng)前網(wǎng)格的功能。
在按下一個(gè)鍵后， 就把TextBox 移動(dòng)到當(dāng)前的位置， 并激活。 在鍵入回車或移動(dòng)到其他網(wǎng)格時(shí)，
就把TextBox 中的內(nèi)容放到網(wǎng)格中。
實(shí)現(xiàn)步驟
1 打開 VB5， 開啟一個(gè)新的工程。
2 在菜單“工程” 中選擇 “部件”， 在列表中選中 “Microsoft FlexGrid Control ..”
3 放一個(gè) MsFlexGrid 控件和一個(gè)TextBox 控件(Text1)到 Form1。 修改MsFlexGrid 控件的名稱為 Grid1，
設(shè)置Grid1 的行，列 為 4， 固定行，列為 0。 設(shè)置 Text1 的 Visiable 為 False， BorderStyle 為
None(0)。
4 在Form1 的代碼中增加聲明：
Const ASC_ENTER = 13 '回車
Dim gRow As Integer
Dim gCol As Integer
5 增加代碼到 Grid_KeyPress 過(guò)程：
Private Sub Grid1_KeyPress(KeyAscii As Integer)
' Move the text box to the current grid cell:
Text1.Top = Grid1.CellTop + Grid1.Top
Text1.Left = Grid1.CellLeft + Grid1.Left
' Save the position of the grids Row and Col for later:
gRow = Grid1.Row
gCol = Grid1.Col
' Make text box same size as current grid cell:
Text1.Width = Grid1.CellWidth - 2 * Screen.TwipsPerPixelX
Text1.Height = Grid1.CellHeight - 2 * Screen.TwipsPerPixelY
' Transfer the grid cell text:
Text1.Text = Grid1.Text
' Show the text box:
Text1.Visible = True
Text1.ZOrder 0 ' 把 Text1 放到最前面！
Text1.SetFocus
' Redirect this KeyPress event to the text box:
If KeyAscii <> ASC_ENTER Then
SendKeys Chr$(KeyAscii)
End If
End Sub
6 增加代碼到 Text1_KeyPress 過(guò)程：
Private Sub Text1_KeyPress(KeyAscii As Integer)
If KeyAscii = ASC_ENTER Then
Grid1.SetFocus ' Set focus back to grid, see Text_LostFocus.
KeyAscii = 0 ' Ignore this KeyPress.
End If
End Sub
7 增加代碼到 Text1_LostFocus 過(guò)程：
Private Sub Text1_LostFocus()
Dim tmpRow As Integer
Dim tmpCol As Integer
' Save current settings of Grid Row and col. This is needed only if
' the focus is set somewhere else in the Grid.
tmpRow = Grid1.Row
tmpCol = Grid1.Col
' Set Row and Col back to what they were before Text1_LostFocus:
Grid1.Row = gRow
Grid1.Col = gCol
Grid1.Text = Text1.Text ' Transfer text back to grid.
Text1.SelStart = 0 ' Return caret to beginning.
Text1.Visible = False ' Disable text box.
' Return row and Col contents:
Grid1.Row = tmpRow
Grid1.Col = tmpCol
End Sub
8 好了。 按 F5 開始測(cè)試。 您可以自由地在 Grid 中移動(dòng)， 按回車可以開始或結(jié)束編輯。
使用MsFlexGrid控件的幾個(gè)函數(shù)
作者：中國(guó)論壇網(wǎng)收集 來(lái)源：http://www.51one.net 加入時(shí)間：2004-8-25
在VB處理數(shù)據(jù)顯示的時(shí)候,使用表格是一種好的方法,雖然DataGrid可以與數(shù)據(jù)源綁定,但是總有美中不足,就是
外觀不好看,所以有時(shí)應(yīng)用MsFlexGrid顯示數(shù)據(jù)還是一種比較好的方法,以下幾個(gè)函數(shù)是用來(lái)控制MsFlexGrid的程序
(本人語(yǔ)言表達(dá)能力有限,還請(qǐng)見諒)

在msflexgrid控件中每一個(gè)cell格的內(nèi)容是不可以由用戶直接編輯的但是我們可以通過(guò)一些小技
巧來(lái)方便的實(shí)現(xiàn)這編輯功能來(lái)擴(kuò)展msflexgrid的應(yīng)用（在實(shí)際應(yīng)用中這是很常用的功能）。
你只需按下面的做即可輕松實(shí)現(xiàn)編輯msflexgrid控件數(shù)據(jù)的功能
例在窗體上放一文本框txtvalue，和一msflexgrid控件grid
‘文本框控件的keypress事件
private sub txtvalue_keypress(keyascii as integer)
‘放入一些處理過(guò)程，如只需輸入數(shù)字時(shí)的處理
dim i
i=1
end sub
private sub txtvalue_change()
grid.text = txtvalue.text
end sub
'在grid的entercell事件中加入下例代碼
private sub grid_entercell()
txtvalue.text = grid.text
txtvalue.selstart = 0
txtvalue.sellength = len(txtvalue.text)
end sub
'當(dāng)用戶輸入數(shù)據(jù)時(shí)直接調(diào)用文本框的keypress事件
private sub grid_keypress(keyascii as integer)
txtvalue_keypress keyascii
end sub
ok,這樣一個(gè)可編輯的msflexgrid控件就完成了，簡(jiǎn)單吧!!
Private Sub fgrid1_click() '單擊MSFlexGrid
sphy = Trim(FGrid1.TextMatrix(FGrid1.Row, 0))
delrecord
End Sub
Private Sub fgrid1_RowColChange()'用上下鍵在MSFlexGrid上選擇
sphy = Trim(FGrid1.TextMatrix(FGrid1.Row, 0))
delrecord
End Sub
Private Sub DeleteRecord()'刪除
Dim I As Integer '
Dim Ssql As String
Dim response As String
response = MsgBox("真的刪除當(dāng)前記錄?", vbInformation + vbYesNo, "警告")
If response = vbYes Then
Ssql = "delete from login where loginname='" & sphy & "'"
gcnLeaguers.Execute (Ssql)
MsgBox "刪除成功！", vbInformation + vbOKOnly, "系統(tǒng)提示"
End If
Exit Sub
End Sub
刪除后可能還要刷新一下，你試試吧
MSHFlexGrid1.SelectionMode = flexSelectionByRow
還是
Private Sub Form_Load()
With MSHFlexGrid1
.FixedCols = 0
.Cols = 2
.Rows = 0
.AddItem "1" & vbTab & "11"
.AddItem "2" & vbTab & "22"
.AddItem "3" & vbTab & "33"
End With
End Sub
Private Sub MSHFlexGrid1_RowColChange()
Static intPrevRow As Long
If MSHFlexGrid1.Row <> intPrevRow Then
intPrevRow = MSHFlexGrid1.Row
Dim i As Long
For i = 0 To MSHFlexGrid1.Cols - 1
MsgBox MSHFlexGrid1.TextMatrix(intPrevRow, i)
Next
End If
End Sub
原理
當(dāng)用戶點(diǎn)擊msflexgrid中的某個(gè)cell格要輸入數(shù)據(jù)時(shí),產(chǎn)生entercell事件，在這里我們對(duì)文本
框進(jìn)行初始化，輸入當(dāng)前cell格中的內(nèi)容，并且選中所有文本。當(dāng)用戶要按下按鍵進(jìn)行輸入時(shí)，就直
接調(diào)用txtvalue的事件，由文本框來(lái)處理.
處理的結(jié)果同grid的當(dāng)前cell同步，使用戶編輯cell格就象使用文本框一樣方便。
網(wǎng)格單元格中文字的多行顯示很簡(jiǎn)單，只要把WordWarp屬性改為True就可以了。
1.VB6自帶MSHFlexGrid只支持2048條記錄顯示,這個(gè)問題通過(guò)裝VB6 的SP6解決.
2.TopRow屬性的使用,這個(gè)屬性可以使用代碼移動(dòng)MSHFlexGrid的行顯示,如要做一個(gè)從上至下的滾動(dòng)顯示，使用這個(gè)屬性解決起來(lái)非常方便
3.使用選碼高亮即選中顯示某一行,如要選中第三行,可以使用代碼:
MSHFlexGrid1.Row = 3
MSHFlexGrid1.TopRow =3
myMSHFlexGrid.ColSel = MSHFlexGrid1.Cols - 1
MSHFlexGrid中單擊某一行變色，如何實(shí)現(xiàn)？
Option Explicit
Public j As Long
Private Sub RowColor(i As Long, j As Long)
'i代表現(xiàn)在點(diǎn)的這一行
Dim n As Long 'n代表列
With Me.MSHFlexGrid1
For n = 1 To .Cols - 1
.Row = i
.Col = n
.CellBackColor = &HC0FFFF
If j > 0 And i <> j Then
.Row = j
.CellBackColor = &HFFFFFF
End If
Next n
j = i
End With
End Sub
Private Sub Form_Load()
With Me.MSHFlexGrid1
.Cols = 5
.Rows = 6
End With
End Sub
Private Sub MSHFlexGrid1_Click()
Call RowColor(Me.MSHFlexGrid1.Row, j)
Debug.Print j
End Sub

i的循環(huán)條件是從1到3，換句話說(shuō)循環(huán)的退出條件就是i大于3，所以當(dāng)循環(huán)結(jié)束時(shí)，i的值就是3+step，由于step默認(rèn)為1，所以i就等于4咯
補(bǔ)充說(shuō)明一下：next
i的作用相當(dāng)于i=i+step，當(dāng)最后一次循環(huán)運(yùn)行時(shí)，i=3，那么當(dāng)運(yùn)行到next時(shí)，i就被自動(dòng)+step，由于step是1，所以i就變?yōu)?了。這個(gè)可能會(huì)讓你更容易理解。
