how to trap an error
hi need some help with this i dont know how to trap errors properly
i have a module passing code from my listbox when user double clicks it (it starts a program using shell function)
now if the file is not found i need to trap the error (err.number is 53 "File Not Found")
when the error is raised i need a msgbox to show stating game is not found and then i need the error to be cleared so that the user can select another line in the listbox.
now the code in the module has 52 shell statments depending on which line in the listbox is double clicked.
below is the code that i need to trap errors on.
Code:
Public Sub Load_Game_Paragon()
If Form1.lblBtnPress.Caption = "4" And Form1.List1.ListIndex = 0 Then

Re: how to trap an error
Try putting this in you sub or function
Code:
Dim int_ErrReturn As Integer
Dim str_ProcName As String
str_ProcName = "Your sub/function name"
On Error GoTo ProcError
'
Code goes between here
'
On Error Resume Next
Exit Function ' you use sub instead of function for subs
ProcError:
g_bln_ErrEdit = False
g_str_ErrProcName = str_ProcName
g_lng_Err = Err
g_str_Error = Error
g_bln_ErrCancel = False
int_ErrReturn = g_f_int_ErrorRoutine(0)
Resume Next
Then put this code in a global module
Code:
Public Function g_f_int_ErrorRoutine(int_ErrNo As Integer) As Integer
Dim str_Time As String
Dim str_Date As Date
str_Time = Time
str_Date = Date
' If it is a program error and not a system error
' Then set error message and error title
If int_ErrNo Then
Select Case int_ErrNo
Case 1: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 2: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 3: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 4: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 5: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 6: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 7: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 8: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 9: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 10: g_str_ErrMsg = "You Have Ended This Application !" & vbNewLine & vbNewLine & _
" Do You Want To Save The Current Information ? (Y/N) " & vbNewLine & vbNewLine & _
" Press Cancel To Return To The Application . "
g_str_ErrTitle = g_str_FormName
Case 11: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 12: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 13: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 14: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 15: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 16: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 17: g_str_ErrMsg = " "
g_str_ErrTitle = " "
Case 18: g_str_ErrMsg = " "
g_str_ErrTitle = " "
End Select
End If
' Change button(s) to yes/no if g_str_ErrMsg = 4
If int_ErrNo Then
Select Case int_ErrNo
Case 4: g_int_ErrButton = 36
Case 9: g_int_ErrButton = 35
Case 10: g_int_ErrButton = 35
Case Else: g_int_ErrButton = 16
End Select
End If
' If program error then display message box and get return
If int_ErrNo Then
g_f_int_ErrorRoutine = MsgBox(g_str_ErrMsg, g_int_ErrButton, g_str_ErrTitle)
g_bln_ErrEdit = False
Open g_str_ErrorLog For Append As #1
Write #1, str_Time, str_Date, g_str_ErrTitle, g_str_ErrMsg, g_int_ErrButton, g_f_int_ErrorRoutine, vbCrLf & vbCrLf
Close #1
Exit Function
End If
' If system error then display message box and get return
g_str_ErrTitle = "Operating / VB System Error in " & _
g_str_ErrProcName
g_str_ErrMsg = "Error # " & _
Trim$(Str$(g_lng_Err)) & _
" - " & _
g_str_Error & vbCrLf & vbCrLf
If g_bln_ErrCancel Then
g_str_ErrMsg = g_str_ErrMsg & _
"This Program will Now Terminate"
g_int_ErrButton = 16
Else
g_str_ErrMsg = g_str_ErrMsg & _
"Cancel Program ( Yes, No )"
g_int_ErrButton = 20
End If
g_f_int_ErrorRoutine = MsgBox(g_str_ErrMsg, g_int_ErrButton, g_str_ErrTitle)
' Open g_str_ErrorLog For Append As #1
'
' Write #1, str_Time, str_Date, g_str_ErrTitle, g_str_ErrMsg, g_int_ErrButton, g_f_int_ErrorRoutine, vbCrLf & vbCrLf
'
' Close #1
If Not g_bln_ErrEdit Then
If g_bln_ErrCancel Then
End
Else
If g_f_int_ErrorRoutine = 6 Then
End
End If
End If
End If
End Function
Be sure to declare the data fields in the app. There may be more than you need in here but this should help.

Re: how to trap an error
Simple, easy, direct, and proper way to catch an error is not to use on error resume next or on error goto 0... For example, you just created the following sub...
Code:
Private Sub MySub()
End Sub
and now to add error trapping to it...
Code:
Private Sub MySub()
On Error GoTo LabelName 'now label name can be almost anything but here I normally copy the subs name
'and use it. So my label name would be MySubError
'exit the sub so the error handler is not invoked
Exit Sub
'now this next line is the label, or as I call it the anchor. If an error occures, the program will jump
'to this point and execute the next line
MySubError:
'and so you can check for that error
If Err.Number = 53 Then
MsgBox "File Not Found! Please Try Again.", vbOkOnly + vbInformation, "Not Found"
Err.Clear
Else
MsgBox "My Sub " & Err.Number & ":" & Err.Description
End If
End Sub
Good Luck

vb5prgrmr is correct about usning on error resume next, I did not notice that I pasted a bit of code that contained that. There was instance when I wanted to use this such as ...
Code:
On Error Resume Next
m_obj_rst.MoveLast
m_obj_rst.MoveFirst
On Error GoTo ProcError
