          msflexgrid1.colwidth(i)=4000
          增加 MsFlexGrid 的編輯功能

          概述
          MsFlexGrid 控件沒(méi)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(kāi) VB5, 開(kāi)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
