Hi, i am having problem with my vb project to clear all item in my form. Below is the code that i am using :
Dim ctrl, obj as control For Each ctrl in Me.controls If typeof ctrl is GroupBox then For Each obj In ctrl.Controls If typeof obj is TextBox or typeof is ComboBox or typeof is ListBox then obj.text ="" End if Next Elseif typeof ctrl is TextBox then ctrl.text = "" End if Next
The error is :
InvalidCastException was unhandled
An unhandled exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
Additional Information : Conversion from string "" to type 'Double' is not valid.
Please Enlighten me. I really do not understand it.
