點選得到行程式碼 
msgrid1.Col就是你選擇的列號 
msgrid1.Row 就是你選擇的行號 
msgrid1.text就是你選擇單元格的內容。

增加 MsFlexGrid 的編輯功能


概述
MsFlexGrid 控制元件沒有提供文字編輯的功能,下面的例子演示瞭如何利用一個TextBox 實現編輯當前網格的功能。

在按下一個鍵後, 就把TextBox 移動到當前的位置, 並激活。 在鍵入回車或移動到其他網格時,

就把TextBox 中的內容放到網格中。

實現步驟
1 開啟 VB6, 開啟一個新的工程。

2 在選單“工程” 中選擇 “部件”, 在列表中選中 “Microsoft FlexGrid Control ..”

3 放一個 MsFlexGrid 控制元件和一個TextBox 控制元件(Text1)到 Form1。 修改MsFlexGrid 控制元件的名稱為 Grid1,

設定Grid1 的行,列 為 4, 固定行,列為 0。 設定 Text1 的 Visiable 為 False, BorderStyle 為

None(0)。

4 在Form1 的程式碼中增加宣告:

Const ASC_ENTER = 13 '回車
Dim gRow As Integer
Dim gCol As Integer

5 增加程式碼到 Grid_KeyPress 過程:

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 增加程式碼到 Text1_KeyPress 過程:

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 增加程式碼到 Text1_LostFocus 過程:

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 開始測試。 您可以自由地在 Grid 中移動, 按回車可以開始或結束編輯。

使用MsFlexGrid控制元件的幾個函式




在VB處理資料顯示的時候,使用表格是一種好的方法,雖然DataGrid可以與資料來源繫結,但是總有美中不足,就是

外觀不好看,所以有時應用MsFlexGrid顯示資料還是一種比較好的方法,以下幾個函式是用來控制MsFlexGrid的程式

(本人語言表達能力有限,還請見諒)


''MsFlexGrid操作函式

''合併列
Public Function MergeCol(GridObj As Object, ByVal StartCol As Long, ByVal EndCol As Long, ByVal

ColValue As String, ByVal CurrentRow As Long) As Boolean
If StartCol > EndCol Or StartCol > GridObj.Cols Or CurrentRow > GridObj.Rows Then
MsgBox "對不起,行列設定錯誤!", vbOKOnly, App.Title
MergeCol = False
Exit Function
End If

For I = StartCol To EndCol
GridObj.MergeCol(I) = True
GridObj.TextArray(faIndex(GridObj, CurrentRow, I)) = ColValue
GridObj.ColAlignment(I) = flexAlignCenterCenter
Next I


GridObj.MergeRow(CurrentRow) = True

MergeCol = True

End Function



''合併行
Public Function MergeRow(GridObj As Object, ByVal StartRow As Long, ByVal EndRow As Long, ByVal

RowValue As String, ByVal CurrentCol As Long) As Boolean
If StartRow > EndRow Or StartRow > GridObj.Rows Or CurrentCol > GridObj.Cols Then
MsgBox "對不起,行列設定錯誤!", vbOKOnly, App.Title
MergeRow = False
Exit Function
End If

For I = StartRow To EndRow
GridObj.MergeRow(I) = True
GridObj.TextArray(faIndex(GridObj, I, CurrentCol)) = RowValue
GridObj.ColAlignment(CurrentCol) = flexAlignCenterCenter

Next I
GridObj.MergeCol(CurrentCol) = True
MergeRow = True

End Function

''轉換索引
Public Function faIndex(GridObj As Object, ByVal row As Integer, ByVal col As Integer) As Long
If row > GridObj.Rows Or row < 0 Or col > GridObj.Cols Or col < 0 Then
MsgBox "對不起,行列設定錯誤!", vbOKOnly, App.Title
faIndex = -1

Exit Function
End If

faIndex = row * GridObj.Cols + col

End Function


''插入行
Public Function SetItem(GridObj As Object, ByVal row As Integer, ByVal col As Integer, ByVal

SetValue As String) As Boolean
If row > GridObj.Rows Or row < 0 Or col > GridObj.Cols Or col < 0 Then
MsgBox "對不起,行列設定錯誤!", vbOKOnly, App.Title
SetItem = False
Exit Function
End If
GridObj.TextArray(faIndex(GridObj, row, col)) = SetValue

SetItem = True
End Function

''得到單元格值
Public Function GetItem(GridObj As Object, ByVal row As Integer, ByVal col As Integer) As String

If row > GridObj.Rows Or row < 0 Or col > GridObj.Cols Or col < 0 Then
MsgBox "對不起,行列設定錯誤!", vbOKOnly, App.Title
GetItem = ""
Exit Function
End If
GetItem = GridObj.TextArray(faIndex(GridObj, row, col))
End Function

在msflexgrid控制元件中每一個cell格的內容是不可以由使用者直接編輯的但是我們可以通過一些小技
巧來方便的實現這編輯功能來擴充套件msflexgrid的應用(在實際應用中這是很常用的功能)。

你只需按下面的做即可輕鬆實現編輯msflexgrid控制元件資料的功能

例在窗體上放一文字框txtvalue,和一msflexgrid控制元件grid

‘文字框控制元件的keypress事件
private sub txtvalue_keypress(keyascii as integer)
‘放入一些處理過程,如只需輸入數字時的處理

dim i
i=1
end sub

private sub txtvalue_change()
grid.text = txtvalue.text
end sub


'在grid的entercell事件中加入下例程式碼
private sub grid_entercell()
txtvalue.text = grid.text
txtvalue.selstart = 0
txtvalue.sellength = len(txtvalue.text)
end sub

'當用戶輸入資料時直接呼叫文字框的keypress事件
private sub grid_keypress(keyascii as integer)
txtvalue_keypress keyascii
end sub

ok,這樣一個可編輯的msflexgrid控制元件就完成了,簡單吧!!

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, "系統提示" 
End If 
Exit Sub 
End Sub 
刪除後可能還要重新整理一下,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
當用戶點選msflexgrid中的某個cell格要輸入資料時,產生entercell事件,在這裡我們對文字
框進行初始化,輸入當前cell格中的內容,並且選中所有文字。當用戶要按下按鍵進行輸入時,就直
接呼叫txtvalue的事件,由文字框來處理.

處理的結果同grid的當前cell同步,使使用者編輯cell格就象使用文字框一樣方便。

網格單元格中文字的多行顯示很簡單,只要把WordWarp屬性改為True就可以了。

1.VB6自帶MSHFlexGrid只支援2048條記錄顯示,這個問題通過裝VB6 的SP6解決.
2.TopRow屬性的使用,這個屬性可以使用程式碼移動MSHFlexGrid的行顯示,如要做一個從上至下的滾動顯示,使用這個屬性解決起來非常方便
3.使用選碼高亮即選中顯示某一行,如要選中第三行,可以使用程式碼:
MSHFlexGrid1.Row = 3
MSHFlexGrid1.TopRow =3
myMSHFlexGrid.ColSel = MSHFlexGrid1.Cols - 1

MSHFlexGrid中單擊某一行變色,如何實現?
