没有必要购买DJ提到的工具。这是我的免费代码:
Public Sub InsertErrHandling(modName As String)
Dim Component As Object
Dim Name As String
Dim Kind As Long
Dim FirstLine As Long
Dim ProcLinesCount As Long
Dim Declaration As String
Dim ProcedureType As String
Dim Index As Long, i As Long
Dim LastLine As Long
Dim StartLines As Collection, LastLines As Collection, ProcNames As Collection, ProcedureTypes As Collection
Dim gotoErr As Boolean
Kind = 0
Set StartLines = New Collection
Set LastLines = New Collection
Set ProcNames = New Collection
Set ProcedureTypes = New Collection
Set Component = Application.VBE.ActiveVBProject.VBComponents(modName)
With Component.CodeModule
' Remove empty lines on the end of the code
For i = .CountOfLines To 1 Step -1
If Component.CodeModule.Lines(i, 1) = "" Then
Component.CodeModule.DeleteLines i, 1
Else
Exit For
End If
Next i
Index = .CountOfDeclarationLines + 1
Do While Index < .CountOfLines
gotoErr = False
Name = .ProcOfLine(Index, Kind)
FirstLine = .ProcBodyLine(Name, Kind)
ProcLinesCount = .ProcCountLines(Name, Kind)
Declaration = Trim(.Lines(FirstLine, 1))
LastLine = FirstLine + ProcLinesCount - 2
If InStr(1, Declaration, "Function ", vbBinaryCompare) > 0 Then
ProcedureType = "Function"
Else
ProcedureType = "Sub"
End If
Debug.Print Component.Name & "." & Name, "First: " & FirstLine, "Lines:" & ProcLinesCount, "Last: " & LastLine, Declaration
Debug.Print "Declaration: " & Component.CodeModule.Lines(FirstLine, 1), FirstLine
Debug.Print "Closing Proc: " & Component.CodeModule.Lines(LastLine, 1), LastLine
' do not insert error handling if there is one already:
For i = FirstLine To LastLine Step 1
If Component.CodeModule.Lines(i, 1) Like "*On Error*" Then
gotoErr = True
Exit For
End If
Next i
If Not gotoErr Then
StartLines.Add FirstLine
LastLines.Add LastLine
ProcNames.Add Name
ProcedureTypes.Add ProcedureType
End If
Index = FirstLine + ProcLinesCount + 1
Loop
For i = LastLines.Count To 1 Step -1
If Not (Component.CodeModule.Lines(StartLines.Item(i) + 1, 1) Like "*On Error GoTo *") Then
Component.CodeModule.InsertLines LastLines.Item(i), "ExitProc_:"
Component.CodeModule.InsertLines LastLines.Item(i) + 1, " Exit " & ProcedureTypes.Item(i)
Component.CodeModule.InsertLines LastLines.Item(i) + 2, "ErrHandler_:"
Component.CodeModule.InsertLines LastLines.Item(i) + 3, " Call LogError(Err, Me.Name, """ & ProcNames.Item(i) & """)"
Component.CodeModule.InsertLines LastLines.Item(i) + 4, " Resume ExitProc_"
Component.CodeModule.InsertLines LastLines.Item(i) + 5, " Resume ' use for debugging"
Component.CodeModule.InsertLines StartLines.Item(i) + 1, " On Error GoTo ErrHandler_"
End If
Next i
End With
End Sub
把它放在一个模块中,每次你向这样的表单或模块添加新函数或子时从即时窗口调用它(Form1 是你的表单的名称):
MyModule.InsertErrHandling "Form_Form1"
它将改变您在 Form1 中的 ode:
Private Function CloseIt()
DoCmd.Close acForm, Me.Name
End Function
到这里:
Private Function CloseIt()
On Error GoTo ErrHandler_
DoCmd.Close acForm, Me.Name
ExitProc_:
Exit Function
ErrHandler_:
Call LogError(Err, Me.Name, "CloseIt")
Resume ExitProc_
Resume ' use for debugging
End Function
现在在模块中创建一个 Sub,它将显示错误对话框,您可以在其中添加将错误插入文本文件或数据库:
Public Sub LogError(ByVal objError As ErrObject, moduleName As String, Optional procName As String = "")
On Error GoTo ErrHandler_
Dim sql As String
MsgBox "Error " & Err.Number & " Module " & moduleName & Switch(procName <> "", " in " & procName) & vbCrLf & " (" & Err.Description & ") ", vbCritical
Exit_:
Exit Sub
ErrHandler_:
MsgBox "Error in LogError procedure " & Err.Number & ", " & Err.Description
Resume Exit_
Resume ' use for debugging
End Sub
如果 proc 中已经存在“On Error”语句,则此代码不会进入错误处理。
