need help in raising events
Jan 13 2005 8:07 PM
hi! I'm just new in programming in vb.net. I have a user control that raises an event which is handled by the form where the control is loaded. the user control and the form are located in two separate projects and the control is loaded dynamically. This is my code for the user control: Public Delegate Sub ClearAllControls(ByVal bytIQAType As Byte) Public Class ctlControl Inherits System.Windows.Forms.UserControl Public Event ClearAllCtrls As ClearAllControls Private Sub btnClearAll_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnClearAll.Click Try RaiseEvent ClearAllCtrls(bytIQAType) Catch ex As Exception Call MsgBox(ex.Message) End Try End Sub End Class This is my code for the form: Public Class frmForm Inherits System.Windows.Forms.Form Public WithEvents ctlCtrl as prjControl.ctlControl Public Sub ctlCtrl_ClearAllCtrls(ByVal bytIQAType As Byte) Handles ctlCtrl.ClearAllCtrls Try 'call clear all of all loaded controls Catch ex As Exception call MsgBox(ex.Message) End Try End Sub End Class My problem is that when RaiseEvent is called it doesn't go to the ctlCtrl_ClearAllCtrls method in frmForm and just moves on to End Try. No error or exception occurs so I don't know what the problem is. Need help pls!
