• Ludmila Koganer Classes and definitions

  Hello. Im learning to create and use classes as work. What I would like to know is how I can create definitions in my classes for methods that show up in the code window.

• Pauly C use radio button group to display a database field value

  I am working on a Forms project storing data in an Access Database, and for several fields I would like to use Radio Button Groups to have the user select from limited options. I can link the groups on the form to the fields in the database, but they appear blank when the record comes up instead of showing a checked state to indicate the value held in the field. I can put a text box on the form and use code to decide which radio button should be checked based on its value, and vice versa for which value to store for a new record, but is there an easier way Given so many other easy ways to do things with the program, i think I must be missing something. Thanks Typically when binding radio buttons to ...Show All

• Parkin The simplest copy n paste destroys code behind link - ridiculous time wasting nonsense

  Novice using vb.net 2005, vb.net 2005 express, vb.net 2005 pro This situation is just down right insulting and another ridiculous time wasting feature of the MS IDE. I've placed a split container on my form. Then cut and pasted a group of controls that are already present on the form with linked code behind already working onto one split panel and another group on another split panel. Nothing works. I've now got to step thru my code and manually update the handles on each and every event from the controls I've cut and pasted just to test the look n feel even before deciding to use the split container model. This: Private Sub btnReports_Click( ByVal sender As System. Object , ByVal e As System.EventArgs) Handles btnReports. ...Show All
