Handling OLE DB Error messages in ASP

I have been asked to put a delete key on certain database fields in an application and know that the ASP will fall over if the user tries to delete a record which is linked to another record in another table which is referentially linked - I have forced this in the relationship.

I do not want all associated records deleted but I do wnat to capture the error message and present it in a more user friendly way.

How do I capture the following screen info so that I can re-present it in a nice neat table.....


Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC Microsoft Access Driver] The record cannot be deleted or changed because table 'Product' includes related records.

/stone/product_select_maintenance.asp, line 218

I do not know the code in ASP but in C++ Builder I handle this as follows.

//Declarations
#include <ComObj.hpp>

//Code
try
{
    /*Delete record from table code*/
}
catch (EOleException &e)
{
    if (e.ErrorCode == 80004005)
    {
        ShowMessage("You are trying to remove a record that are linked with records in another table....");
        /*Error has been captured so you can do what you like here!*/
    }
}

Hope this code can give you a hint on how to handle the error.

Thanks for the thought. It looks very like javascript .... could a chunk of javascript in the header grab the message and put a pop up box on the screen (or re-direct to another page) and stop the message displaying as normal ?

Since the catch (EOleException &e) prevents the compiler from throwing the default message you are the one handeling what to be done. If I would not have entered the ShowMessage dialog I would have gotten the error but not know about it since I redirected the error to my error handler.

This use case outlines the migration challenges that organizations face and how the Acronis AnyData Engine supports physical-to-physical (P2P), physical-to-virtual (P2V), virtual to physical (V2P), and cross-virtual (V2V) migration scenarios to address these challenges.

Thanks for your help KeyPakt but this has not provided me with the solution. I have re-consulted my books and have resolved the problem very simply by using the VBScript object:

On Error resume next
                    MyConn.Execute="DELETE * FROM colour_group WHERE colour_group_ID="&request("colour_group_ID")&" "
                    If err.Number<>0 then
                        response.redirect"product_select_maintenance.asp?update_routine_accessed=yes&error=colour&description="&colour_group&" "   
                        err.clear
                    End If

As the only error which is likely to occur in my situation is the failure to delete the item selected (it is only this bit of SQL code which I am trapping) then if it fails I get an error which allows me to report the failure of the system to delete and the reason why.

Sorry, no points. Question withdrawn.
