增加 MsFlexGrid 的编辑功能
概述
MsFlexGrid 控件没有提供文本编辑的功能，下面的例子演示了如何利用一个TextBox 实现编辑当前网格的功能。
在按下一个键后， 就把TextBox 移动到当前的位置， 并激活。 在键入回车或移动到其他网格时， 就把TextBox 中的内容放到网格中。
实现步骤
1 打开 VB5， 开启一个新的工程。
2 在菜单“工程” 中选择 “部件”， 在列表中选中 “Microsoft FlexGrid Control ..”
3 放一个 MsFlexGrid 控件和一个TextBox 控件(Text1)到 Form1。 修改MsFlexGrid 控件的名称为 Grid1， 设置Grid1 的行，列 为 4， 固定行，列为 0。 设置 Text1 的 Visiable 为 False， BorderStyle 为 None(0)。
4 在Form1 的代码中增加声明：
Const ASC_ENTER = 13 '回车
Dim gRow As Integer
Dim gCol As Integer
5 增加代码到 Grid_KeyPress 过程：
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 增加代码到 Text1_KeyPress 过程：
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 增加代码到 Text1_LostFocus 过程：
Private Sub Text1_LostFocus()Dim tmpRow As IntegerDim 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.RowtmpCol = Grid1.Col' Set Row and Col back to what they were before Text1_LostFocus:Grid1.Row = gRowGrid1.Col = gColGrid1.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 = tmpRowGrid1.Col = tmpColEnd Sub
