Hello, Excuseme by my bad and wrong English:

Im I user of your product MYDAC in past days i buy this components,
My Name is Iván Caballero Cano

I have problems instaling using the software.
I use Delphi 5.

I Have 2 MyTable components.
I Have a MYSQL Database Versiòn 5.0.45

In a first table I have a field named "seccion" that is a INT(10)
In the second table i also have a field named "menu" that is a INT(10)

When i configure a DBLookUPCombobox component to get a value of first table to write this value in the second table
i get a error message when i run the program:

Project Project1.exe raised exception class EvariantError with message 'Invalid variant operation', Proccess stoped.


Can you help me with this problem?

Thank you

Set the TMyConnectionOptions.OptimizedBigInt property to True to map LargeInt fields to Integer fields.

Hello:

Thanks to respond my question.

This option exist in mydac for delphi 5???

I dont see it.

My version of mydac is 4.00.25 and maybe in this version the "OptimizedBigInt " propertie dont exist!

What can I do to resolve the problem?

Thanks.

The OptimizedBigInt property was added in the MyDAC version 5.20.1.14. Please, upgrade to the latest MyDAC build to solve the problem.
