knowing the Control Type dynamically.

Hi All,
Recently I was programming in VB and I came across a requirement. I wanted to know programatically what type each control is in a screen . Suppose a form has a command button, a checkbox, a textbox and a listbox. In my program code ( say open window event of the form) I want to know what type of control is Controls(3). I adressed the problem in an indirect way by naming the controls in a predefined format (e.g all textbox controls were named as txt...). In the program I checked controls(i).name . Can anybody give me a more general solution to this problem. If it is not possible in VB can VC++ handle this situation more gracefully ?

Thanking you in advance.

Try TypeName(Controls(3)). The TypeName function returns the Object Type when passed an object.

Hi

You can check the type of each control on your form by using either the TypeName function that returns a string of the control's type, or the 'TypeOf .. Is ..' command, eg:


Dim ctl as Control

for Each ctl In me.Controls
Debug.print TypeName$(ctl)
If TypeOf ctl is TextBox then
' DO something
ElseIf TypeOf ctl is CommandButton then
' Do something else
'
' etc.
End If
next
