Main Form Properties

[Ibrahim]

Hi there,

am new to this field, so i wanted to run the form without close button.
so how i could do to disable the close button on the form.
and instead of using the close button i need to use button and display message
yes/no and if yes to close the form.

thanks

This will take a little bit of code to do.

- Set the FormBorderStyle of the Mainform to none
- Add a Button from the All Windows Forms group in the ToolBox
- Double click to the button to get back to the code
- Add this code:

Code: [Select]

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        If MsgBox("Are you sure?", MsgBoxStyle.YesNo) = MsgBoxResult.Yes Then
            Close()
        End If
    End Sub

- in the Properties window of the form, click the lightening bolt to see the event list
- double click in the FormClosing event to get back to the code
- put in this code:

Code: [Select]

    Private Sub MainForm_FormClosing(sender As System.Object, e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
        If MsgBox("Are you sure?", MsgBoxStyle.YesNo) = MsgBoxResult.No Then
            e.Cancel = True
        End If
    End Sub

You can add more forms to a project by right clicking the AdvancedHMI project in Solution Explorer and select Add->Windows Form

To communicate with multiple PLCs, add more drivers to a form, then set the ComComponent property of each control to tell it which PLC to retrieve the data from.

Try this:

  Private Sub MainForm_FormClosing(sender As System.Object, e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
        If MsgBox("Are you sure?", MsgBoxStyle.YesNo + MsgBoxStyle.Exclamation, "Title") = MsgBoxResult.No Then
