vb中msflexgrid的使用举例（转）
【From】http://yiceyang.blog.163.com/blog/static/1118333120075604131404/
1、 将文本赋值给MsFlexGrid的单元格
MsFlexGrid.TextMatrix(3,1)=”Hello”
2、 在MsFlexGrid控件单元格中插入背景图形
Set MsFlexGrid.CellPicture=LoadPicture(“C:\temp\1.bmp”)
3、选中某个单元
MsFlexGrid.Row=1
MsFlexGrid.Col=1
4、用粗体格式化当前选中单元
MsFlexGrid.CellFontBold=True
5、 添加新的一行
使用AddItem方法,用Tab字符分开不同单元格的内容
dim row as string
row=”AAA”&vbtab&”bbb”
MsFlexFrid1.addItem row
6、怎样来实现MSFlexGrid控件单数行背景为白色，双数的行背景为蓝色?
Dim i As Integer
With MSFlexGrid1
.AllowBigSelection = True    ’ 设置网格样式
.FillStyle = flexFillRepeat
For i = 0 To .Rows - 1
.Row = i: .Col = .FixedCols
.ColSel = .Cols() - .FixedCols - 1
If i Mod 2 = 0 Then
.CellBackColor = &HC0C0C0    ’ 浅灰
Else
.CellBackColor = vbBlue ’ 兰色
End If
Next i
End With
7、MSFlexGrid控件如何移到最后一行
MSFlexGrid1.TopRow = MSFlexGrid1.Rows – 1
8、如何判断msflexgrid有无滚动条
Declare Function GetScrollRange Lib "user32" (ByVal hWnd As Long, ByVal nBar As Long, lpMinPos As Long, lpMaxPos As Long) As Long
Public Const SB_HORZ = &H0
Public Const SB_VERT = &H1
Public Function VsScroll(MshGrid As MSHFlexGrid) As Boolean           ’判断水平滚动条的可见性
Dim i As Long
VsScroll = False
i = GetScrollRange(MshGrid.hWnd, SB_HORZ, lpMinPos, lpMaxPos)
If lpMaxPos <> lpMinPos Then VsScroll = True
End Function
Public Function HeScroll(MshGrid As MSHFlexGrid) As Boolean           ’判断垂直滚动条的可见性
Dim i As Long
HeScroll = False
i = GetScrollRange(MshGrid.hWnd, SB_VERT, lpMinPos, lpMaxPos)
If lpMaxPos <> lpMinPos Then HeScroll = True
End Function
9、程序运行时，想动态增加MSFlexgrid的列数
在第2列后插入一列：
Private Sub Form_Load()
Me.MSHFlexGrid1.Cols = 5
MSHFlexGrid1.Rows = 2
For i = 0 To Me.MSHFlexGrid1.Cols - 1
Me.MSHFlexGrid1.TextMatrix(0, i) = i
Me.MSHFlexGrid1.TextMatrix(1, i) = i
Next
End Sub
Private Sub Command1_Click()
Me.MSHFlexGrid1.Cols = Me.MSHFlexGrid1.Cols + 1
Me.MSHFlexGrid1.ColPosition(5) = 3
End Sub
10、 MSFlexGrid中的对齐功能的使用
设置MSFlexGrid1.ColAlignment(index)=n
11、得到MSFlexGrid控件中当前选中的一行
msflexgrid1.rowsel就是当前选中行
12、 如何通过代码调节列宽度
msflexgrid1.colwidth(i)=4000
增加 MsFlexGrid 的编辑功能 [转帖]
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 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
