Create Button In VB.NET Programmatically And Save It as Permanence

Hi, All Experts ... Argent, Please HELP ...

How to create a Button in Runtime and save it as Permanence. I Means to create Button or any control using coding but need it to save for next time using without using database to keep. Eg: Create a button during runtime, and the control will save permanencely for next use.

Not sure what you mean? :confused: A dynamic button is a dynamic button. Whether you save the settings for this button in an INI file, or even the registry, it will still have to be created dynamically from there.

Is this what you're looking for?

Code:

---


Public Class Form1

 
Private myButton As Button


Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Try

            myButton = New Button

            myButton.Size = New System.Drawing.Size(80, 24)
            myButton.Location = New System.Drawing.Point(40, 40)
            myButton.Text = "myButton"
            Controls.Add(myButton)

            AddHandler myButton.Click, AddressOf myButtonClick


        Catch ex As Exception

        End Try
    End Sub

    Private Sub myButtonClick()

        Try
            MessageBox.Show("OK")
        Catch ex As Exception

        End Try
    End Sub

 
End Class

Thanks, For Reply. YES, Currently I Save the setting in Local MS SQL Database, but every time in load slowly because too many setting inside, so what i want to find is the way to faster it ... Is that is i save those setting in .INI file will load faster ? Thanks.

Well there would be less overhead reading from an INI file than an SQL Server database. So yes. However, that may not even be the source of your performance problems. Maybe there is something else causing it. Can't really be sure since we don't have the code you're using.

Try the INI file route and see if that improves it.

Oh, Thanks, I Will Try it using .INI file, and Another Question, how to make a dynamic created Button can be moveable follow the mouse drag position ? thanks.

By the way, how to write/read/create using .INI file ... Sry, I very fresh in VB.NET ... Thanks in advanced .

Hi, Have anyone expert can tell me how to make faster Loading Control (Many Control) Like Button Dynamiclly Create at Runtime. The Loading for my from is slow and high latency until can see it load one-by-one. Becasue the Button Setting like position is all keep in Local Database. Thanks.

As Curt_c mentioned in his code, use AddHandler. Here is a link explaining how it works :

That is what we are trying to do. But I think you show really show us some of your code; there might be something else causing all the problems.

Thks, but can gif any sample code on it ... i still cant successful apply for my case ... Thanks

Hi,

How many buttons are you creating on your form? if there's any delay it's probably from reading the database and not form creating the controls

Why don't you just use 2 variables to locate your controls? Store those in a ini file.

Code:

---


    Public Class Form1

    Private myButtons(30) As Button


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim i As Integer = 0
        Dim xStep As Integer = 40
        Dim yStep As Integer = 20
        Try

            For i = 0 To myButtons.Length - 1

                myButtons(i) = New Button

                myButtons(i).Size = New System.Drawing.Size(80, 24)
                myButtons(i).Location = New System.Drawing.Point(xStep, yStep)
                myButtons(i).Text = "Button " & i
                'myButtons(i).Visible = False
                Controls.Add(myButtons(i))

                AddHandler myButtons(i).Click, AddressOf myButtonClick

                yStep += 40
                If i = 9 Or i = 19 Then
                    xStep = xStep + 100
                    yStep = 20
                End If

            Next i

            'For i = 0 To myButtons.Length - 1
            '    myButtons(i).Visible = True
            'Next i

        Catch ex As Exception

            MessageBox.Show(ex.Message)

        End Try

    End Sub

    Private Sub myButtonClick(ByVal sender As System.Object, ByVal e As System.EventArgs)

        Try
            MessageBox.Show(sender.ToString())
        Catch ex As Exception

        End Try
    End Sub

End Class
