wincc中使用VB 实现报表

VB中MsFlexGrid控件的使用细则(收集)


>> 将文本赋值给MsFlexGrid的单元格

MsFlexGrid.TextMatrix(3,1)=”Hello”


>> 在MsFlexGrid控件单元格中插入背景图形

Set MsFlexGrid.CellPicture=LoadPicture(“C:\temp\1.bmp”)


>>选中某个单元

MsFlexGrid.Row=1

MsFlexGrid.Col=1


>>用粗体格式化当前选中单元

MsFlexGrid.CellFontBold=True


>> 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



>>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


>> MSFlexGrid控件如何移到最后一行

MSFlexGrid1.TopRow = MSFlexGrid1.Rows – 1


>>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


>>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


>> 请教MSFlexGrid中的对齐功能的使用

设置MSFlexGrid1.ColAlignment(index)=n



>>得到MSFlexGrid控件中当前选中的一行

msflexgrid1.rowsel就是当前选中行


>> 如何通过代码调节列宽度

msflexgrid1.colwidth(i)=4000
