Re: how to call an event inside another event

Lets say that in the loadmain you set text for a label like this
Label1.Text = "Load Main"
But you want to do the same thing if you click a button, then create a function called for example

VBNET Syntax (Toggle Plain Text)
private void SetLabel()
{
Label1.Text = "Load Main"
}
private void SetLabel()
{
Label1.Text = "Load Main"
}

then your load main will have this

VBNET Syntax (Toggle Plain Text)
private void LoadMain()
{
SetLabel()
}
private void LoadMain()
{
SetLabel()
}

and the button event

VBNET Syntax (Toggle Plain Text)
private void buttonevent()
{
SetLabel()
}
private void buttonevent()
{
SetLabel()
}

I hope you understand the idea. regards

Re: how to call an event inside another event

VB.NET Syntax (Toggle Plain Text)
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Try
            MsgBox("Form Load")
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Try
            Call Form1_Load(sender, e)
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
 
    End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Try
            MsgBox("Form Load")
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Try
            Call Form1_Load(sender, e)
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try

    End Sub

But i suggest u to write the form load code into procedure,& call that procedure on form load & on button click,instead of calling form load event again
