Commands on Form Load - vb.net

Question

I have a command in a form which activates on Form Load which is as follows
Private Sub frm_15_IssueWarning_Load(sender As Object, e As EventArgs) Handles MyBase.Load
lbl_incidentid.Text = frm_6_UpdateIncident.lbl_incidentid.Text
'checks to see if a containment already exists for the Incident, if it does, hide the save containment button
Dim SqlString As String = "select [containmentid],[incidentid],[containmentdate],[containment] from [containment] WHERE [incidentid] = #incidentid"
Using conn As New OleDbConnection(ConnString)
Using command As New OleDbCommand(SqlString, conn)
command.Parameters.AddWithValue("#incidentid", lbl_incidentid.Text)
Using adapter As New OleDbDataAdapter(command)
conn.Open()
Dim reader As OleDbDataReader = command.ExecuteReader()
Try
If reader.Read() Then
Button1.Visible = False
Else
Button1.Visible = True
End If
Finally
reader.Close()
End Try
End Using
End Using
End Using
And all this works great, however the first command
lbl_incidentid.Text = frm_6_UpdateIncident.lbl_incidentid.Text
If I remove this line and place it in form 6 so that when pressing the button on form 6 to open form 15 it includes the line
lbl_incidentid.Text = frm_15_IssueWarning.lbl_incidentid.Text
The rest of the command on form load no longer works, previously this has'nt been a problem because you could only access form 15 from one location but now this is changing so the form can be opened from various locations. Is there a command I can write here so that the form knows what form was open/pressed in order to make it here and act accordingly or can anyone suggest another way round this issue? I apologise if this doesnt make much sense, its a bit of a ramble.

Answer 1

In the end I changed the forms a little, instead of opening the form and closing the previous form straight away I inserted an if statement to see what previous form was open before closing it so the new form could act accordingly, please see example below
'checks to see which form is open to see where to get incident if from
If frm_6_UpdateIncident.Visible = True Then
Me.lbl_incidentid.Text = frm_6_UpdateIncident.lbl_incidentid.Text
frm_6_UpdateIncident.close()
End If
If frm_17_IncidentView.Visible = True Then
Me.lbl_incidentid.Text = frm_17_IncidentView.lbl_incidentid.Text
frm_17_IncidentView.close()
End If
It was actually really simple, no idea why I didint think of this in the first place
