针对MSHFlexGrid的一系列通用方法-项目中实践代码分享

1.给MSHFlexGrid填充数据通用方法

'自定义报表填充程序 fgrid
Public Function ShowformfData(Resultset As ADODB.Recordset, ary As Variant, fg As MSHFlexGrid) As Variant
   Dim cl As field
   Static GridSetup As Boolean
   Dim MaxL As Long
   Dim Op As Long
   Dim rsl As ADODB.Recordset
   Dim rows, sl, field_value As Variant
   Dim i As Long
   Dim j, k As Long
 
'On Error GoTo ShowDataEH
   Set rsl = Resultset
 '------------------------------------------
 '等ERP系统全部导入到SQL SERVER 中才可用下面两行代码
 '如果不连AS400 ，则直接用下面函数
   If rsl.EOF Then
    Exit Function
   End If
 
   ShowMSHFlexGrid fg, rsl, ary
   Exit Function
 '
fg.Clear
fg.Cols =
fg.rows =
fg.ScrollTrack = True
'fg.ScrollTrack = False
Op =
fg.Enabled = True
If rsl.EOF Then
  MsgBox ("没有满足条件的记录,请重新修改您的查询条件")
  fg.rows =
  fg.Enabled = False
  Exit Function
Else
   fg.Visible = True
    For i =  To rsl.Fields.count
        fg.Cols = fg.Cols +
         If i =  Then
         fg.colwidth() =
         Else
 
               fg.Col = Op
               If rsl.Fields(Op - ).DefinedSize >  Then
               MaxL =
               Else
               MaxL = rsl.Fields(Op - ).ActualSize +
               End If
               If MaxL >  Then MaxL =
                   If MaxL <  Then MaxL =
                      fg.colwidth(fg.Col) = MaxL *
                      Op = Op +
          End If
         fg.TextMatrix(, i) = ary(i)
      'FG.TextMatrix(0, i) = rsl.Fields(i).Name
 
     Next i
      'Cols = fg.Cols + 1
      'For I = 0 To rsl.Fields.Count
      'fg.TextMatrix(0, I) = ary(I)
      'Next I
    fg.rows =
    k =
    If Not (rsl.BOF And rsl.EOF) Then
     i =
     Do While Not rsl.EOF
 
       For j =  To rsl.Fields.count
         If j =  Then
         fg.TextMatrix(fg.rows - , j) = k
         Else
 
            If Not IsNull(rsl.Fields(j - ).Value) Then
                 fg.TextMatrix(fg.rows - , j) = Trim(rsl.Fields(j - ).Value)
            End If
            If rsl.Fields(j - ).Type = adChar Then
                  fg.ColAlignment(j) =
            End If
 
          End If
       Next j
         fg.rows = fg.rows +
         fg.TopRow = fg.TopRow +
         fg.Refresh
 
         rsl.MoveNext
        k = k +
     Loop
    fg.rows = fg.rows - 
 
    End If
 
End If
If fg.rows >  Then
    fg.TopRow =
    fg.Refresh
  End If
 
  SetRowColor fg
  fg.FixedRows =
  fg.row =
  fg.Col = 
 
'b:
    Exit Function
 
'ShowDataEH:
'    MsgBox err & vbCrLf & Error$
'    fg.Visible = False
'    Resume b
 
End Function

2.更高效的方法获取是这样的，是今天在项目中必要要解决速度问题才弄出来的，而且即简单又快捷

Dim rsConstitute As ADODB.Recordset
 
txtsql = "select SSFXDM,KCWPDM,XTDWDM,SSZJYL from tabv "
     Set rsConstitute = Query(txtsql, msgtext)
 
     Set FGridCheck.DataSource = rsConstitute

3.针对MSHFlexGrid的一系列通用方法：

Public Function fgclear(fg As MSHFlexGrid)
'
    fg.Clear
    fg.rows =
    fg.Cols =
    fg.FixedRows =
    fg.FixedCols =
    fg.colwidth() =
    fg.colwidth() =
    fg.row =
    fg.Col =
End Function
 
' 设置MSHFlexGrid每列的颜色
Public Function SetColColor(fg As MSHFlexGrid)
'
Dim i
fg.FillStyle =
For i =  To fg.Cols -
    fg.Col = i
    If i Mod  <>  Then
        fg.row =
        fg.RowSel = fg.rows -
        fg.CellBackColor = &HC0FFFF
    End If
Next i
 
fg.FillStyle =
fg.row =
fg.Col = 
 
End Function
 
' 设置MSHFlexGrid每列的颜色
Public Function colw(fg As MSHFlexGrid) As String
'
Dim i
Dim S
S = ""
For i =  To fg.Cols -
    S = S & "fg.ColWidth(" & i & ")=" & fg.colwidth(i) & " '" & fg.TextMatrix(, i) & "   " & Chr() & Chr()
Next i
colw = S
 
End Function

Public Sub markfg1(ByRef fg As MSHFlexGrid, lb As Label, countlb As Label, delbutton As CommandButton)
Dim r, c
Dim markdgcount As Integer
r = fg.row
c = fg.Col
 
If r <>  Then
    If InStr(fg.TextMatrix(r, ), "√") =  Then
        fg.TextMatrix(r, ) = "√ " & fg.TextMatrix(r, )
        fg.Col =
        fg.CellAlignment = 
 
        For i =  To fg.Cols -
        fg.Col = i
        fg.CellBackColor = &HFF&  '红色      '蓝色&H8000000D
        Next
 
        If countlb.Caption = "" Then
            markdgcount =
        Else
            markdgcount = CInt(countlb.Caption) +
        End If
    Else
        fg.TextMatrix(r, ) = Right(fg.TextMatrix(r, ), Len(fg.TextMatrix(r, )) - )
    If Trim(fg.TextMatrix(fg.row, )) = "N" Then
    If r Mod  =  Then
        For i =  To fg.Cols -
            fg.Col = i
            fg.CellBackColor = &HE0E0E0
        Next
    Else
        For i =  To fg.Cols -
            fg.Col = i
            fg.CellBackColor = &HFFFFFF
        Next
    End If
    Else
    For i =  To fg.Cols -
    fg.Col = i
    fg.CellBackColor = &H80FF80
    Next
    End If
        If countlb.Caption = "" Then
            markdgcount =
        Else
            markdgcount = CInt(countlb.Caption) -
        End If
    End If
If markdgcount <>  Then
    countlb.Caption = markdgcount
    lb.Caption = "已选择了 " & CStr(countlb.Caption) & " 条记录！"
    delbutton.Enabled = True
Else
    countlb.Caption = ""
    lb.Caption = ""
    delbutton.Enabled = False
End If
End If
End Sub
