Hello Guys,

In the past, I had developed a function in Clipper that search an information in another table, and get that information to validate an Edit Control.

For example: in an edit control that user must insert a product code, if the user press a button, the system shows the products table in a grid, and let the user pick one product, double clicking on them or clicking and selecting an OK button.

This function gets the product code in this window and populate this code in the control that the user had the focus.

The same principle is that user must input a valid product code, that exists in another table, and don't go to another edit control until this code in inserted or the operation is canceled by hit the Cancel button or ESC key.

Is hard to implement this in Windev?
