>i am new to vb.net and i dont know how to create custom contols in vb.net and i am also not getting it into any book..plz tell me the steps for creating contols or tell me any book or ebook which in detail cover this topic.<OK, this is C# code, but the basic concepts are the same:
Basically, you'll want a class library that contains your sub-classed UI controls, like textbox, button, etc. Something like this:
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace MyCompany.WinUI.MyClasses
{
public class MyComboBox : System.Windows.Forms.ComboBox
{
}
public class MyTextBox : System.Windows.Forms.TextBox
{
}
public class MyButton : System.Windows.Forms.Button
{
}
}
That's it. These controls can't be sub-classed visually, but as you can see, it's easy enough to do it in code. I have all the basic controls sub-classed in one class library file. Once they're added to the ToolBox, then can be dragged onto any design surface in the IDE.
To add to a ToolBox:
When you have the IDE open in the designer view (not the code view), go to the ToolBox, right-click anywhere and choose the Add/Remove Items (in 2.0, it's "Choose Items..."), click on Browse and find the .DLL where your sub-classed controls are (you obviously needed to have compiled the class library after you created it). That's it ... they'll then be added to your ToolBox.
