I am using a dropdown datawindow which allows editing. When i am editing a correct value in it everything works fine. (i am using this datawindow to select a bank. bank_descr appears and bank_code is returned to the program ). However when i am giving a bank code that does not exist in the dropdown list i am not receiving any error indication. i know that i can check the whole situation thru itemchanged event. Is it possible to do it with some other way?

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.
