Re: Question About CDialog class

["Alexey Parshin" <alexeyp@gmail.com>]

In your code, you are reading and setting the data from the
controls(widgets) using value(). In SPTK, you should use the method data()
instead.

So, this code:
////AND THIS LINE               txt_ID-> ????????
                       txt_Nombre->value(ps[0]);
                       txt_Depto->value(ps[2]);
                       txt_Cargo->value(ps[3]);

becomes:
                       txt_ID->data( listView2.data() );
                       txt_Nombre->data(ps[0]);
                       txt_Depto->data(ps[2]);
                       txt_Cargo->data(ps[3]);

If your compiler complains in:
                       txt_ID->data( listView2.data() );
the use:
                       txt_ID->data( (int) listView2.data() );
