Question
How to fix this error: OIP-04119: Data has been modified
I have a VB6.0 application with editable DBGrid and oracle
data control and some textBox. The DBGrid and textBoxs are bound to the ORADC.
I have three buttons, new, delete and save.
When i click the New button, i fill the textboxs. Then i click Save Button to save the new record.
The problem is - after i click Save button, if i want to make change to this record and click Save button again(or if i want to delete this new record), i always get this message
Run-time error '440': OIP-04119: Data has been modified.
I cannot fix this bugs and don't know what cause it, and i cannot get any information from the website. So i have to ask some experts for help.
Please help me. Thank you

Hello,
OO4O does have some bugs in ver 7.2.2 and older with update problems. Try and use the dirty_write method during the CreateDynaset method. This will allow you to rewrite over previously updated info. It should look something
like the following;
Set yourOraDynaset = yourOraDatabase.CreateDyna
If you use ORADC, set the DirtyWrite property to TRUE
Add oradcItem.DirtyWrite = True to your code and it will works fine.
Private Sub mnuitmSave_Click()
On Error GoTo Errhandler
oradcItem.DirtyWrite = True
If oradcItem.EditMode = dbEditNone Then
oradcItem.Recordset.Edit
End If
oradcItem.Recordset.Update
DBGrid1.AllowAddNew = False
Errhandler:
If Err.Number > 0 Then
MsgBox Err.Source & " " & Err.Description, vbCritical, "Error"
End If
End Sub

Could you rewrite this Sub and check.
Private Sub SSCommandUpdate_Click()
On Error GoTo Errhandler
If Not DBGrid1.DataChanged Then
oradcItem.Recordset.Edit
DBGrid1.DataChanged = True
End If
oradcItem.Recordset.Update
DBGrid1.AllowAddNew = False
Errhandler:
If Err.Number > 0 Then
MsgBox Err.Source & " " & Err.Description, vbCritical, "Error"
End If
End Sub
Good luck.
