[2005] custom messagebox

[hockey1314]

Ok maybe im just being lazy. But maybe there is a cool new trick i will learn.

I need a msgbox that basicly just asks the user 1,2,3,or4 Each one could be on a button. So no "input" would be needed.

Then my code would do something based on what was selected.


Dont really want to create a new form for this and have to pass values back and forth. Just wanted a simple pop up.


Any ideas or suggestions. Or am I just better off creating a tiny form and dealing w/ passing the values back and forth.

Nope message boxes are strictly limited in terms of what they can present. It is only a few lines of code to write your own popup though.

[hockey1314]

do you have an example of a simple popup then?

or is it just building a new form and going from there?

[Bulldog]

It can be done, see http://www.knowdotnet.com/articles/a...dapicalls.html (this is in C# but should be easy enough to convert).

It might be quicker to just make a small form...

Edit: Here's a VB example http://vbnet.mvps.org/index.html?cod...ssageboxex.htm

[keystone_paul]

Fraid so - but all you need is a start function that accepts your four options as strings, display four buttons and set their captions, display the form as a dialog, wait for a click and then return the name of the selected item and close the form.

Bulldog,

Your right...looks simpler to create you own form...lOL

Paul,

I guess form time is the way to go..

Ok maybe im just being lazy.

No maybe about it.

Create your own using a form. This is something that you will, or at least theoretically you will, be able to use in a whole lot of different projects.

[hockey1314]

Ok i built my own little form for this. But I am stuck.

I pass the variables to the new little pop up form. But I am missing how to call the form as a function so i can get the result of wich radio button was selected.

I put a comment in where i think a function would be needed to get the return but have never asked for info back from a form before. Only sent it to a new form.

Any guidence?

I did a simple moc up to get it working then will go for the real deal. Form 1

Public Class Form1
    Dim total As Integer = 3
    Dim strtxt(5) As String

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        ' This needs to be a function that then sets the restults to label2.txt
        
        Dim NewMDIChild As New Form2(total, strtxt)
        NewMDIChild.Show()

    End Sub

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim txt1 As String = "1st line"
        Dim txt2 As String = "2nd line"
        Dim txt3 As String = "3rd line"
        Dim txt4 As String = "4th line"
        Dim txt5 As String = "5th line"
        strtxt(0) = txt1
        strtxt(1) = txt2
        strtxt(2) = txt3
        strtxt(3) = txt4
        strtxt(4) = txt5
    End Sub
End Class

Form 2

Public Class Form2
    Dim ttl As Integer
    Dim Tstring(5) As String

    Public Sub New(ByVal totalvar As Integer, ByVal txtstr() As String)
        InitializeComponent()

        ttl = totalvar
        Tstring = txtstr
    End Sub

    Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim radioarray(5) As RadioButton

        radioarray(0) = RadioButton1
        radioarray(1) = RadioButton2
        radioarray(2) = RadioButton3
        radioarray(3) = RadioButton4
        radioarray(4) = RadioButton5


        For count As Integer = 0 To 4
            radioarray(count).Visible = False
        Next
        For count As Integer = 0 To ttl
            radioarray(count).Text = Tstring(count)
            radioarray(count).Visible = True

        Next
    End Sub
End Class

If for example you have a TextBox on the child form, you can interrogate the child forms controls after it is closed, like this;

        Dim NewMDIChild As New Form2()
        NewMDIChild.ShowDialog()
        ' After the sub-form closes, the control data is still available
        MessageBox.Show(NewMDIChild.TextBox1.Text)

Since you're showing a kind of MessageBox, then ShowDialog is appropriate.

[hockey1314]

so would that be true with radio buttons too. Basiclly i want to know wich radio button they selected. Then knowing that I can grab the correct text.

[Bulldog]

That's the idea, I suggest you evaluate them in the sub-form and just pass the 'conclusion' back to the main form.

[hockey1314]

Ok i gave that a shot but my message box pops back blank. So either i screwed something up assigning the info or its not getting it back when the form closes.

Form 1

Public Class Form1
    Dim total As Integer = 3
    Dim strtxt(5) As String

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        ' This needs to be a function that then sets the restults to label2.txt
        
        Dim NewMDIChild As New Form2(total, strtxt)
        NewMDIChild.ShowDialog()
        MessageBox.Show(NewMDIChild.Label1.Text)

    End Sub

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim txt1 As String = "1st line"
        Dim txt2 As String = "2nd line"
        Dim txt3 As String = "3rd line"
        Dim txt4 As String = "4th line"
        Dim txt5 As String = "5th line"
        strtxt(0) = txt1
        strtxt(1) = txt2
        strtxt(2) = txt3
        strtxt(3) = txt4
        strtxt(4) = txt5
    End Sub
End Class

Form 2

Public Class Form2
    Dim ttl As Integer
    Dim Tstring(5) As String

    Public Sub New(ByVal totalvar As Integer, ByVal txtstr() As String)
        InitializeComponent()

        ttl = totalvar
        Tstring = txtstr
        Dim answer As String = ""

        If RadioButton1.Checked = True Then
            answer = RadioButton1.Text
        ElseIf RadioButton2.Checked = True Then
            answer = RadioButton2.Text
        ElseIf RadioButton3.Checked = True Then
            answer = RadioButton3.Text
        ElseIf RadioButton4.Checked = True Then
            answer = RadioButton4.Text
        ElseIf RadioButton5.Checked = True Then
            answer = RadioButton5.Text
        End If

        Label1.Text = answer


    End Sub

    Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim radioarray(5) As RadioButton

        radioarray(0) = RadioButton1
        radioarray(1) = RadioButton2
        radioarray(2) = RadioButton3
        radioarray(3) = RadioButton4
        radioarray(4) = RadioButton5


        For count As Integer = 0 To 4
            radioarray(count).Visible = False
        Next
        For count As Integer = 0 To ttl
            radioarray(count).Text = Tstring(count)
            radioarray(count).Visible = True

        Next
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Me.Close()

    End Sub
End Class

I changed form 2 to this and it fixed it

now is there a way to display the radio buttons in that group that does not automaticly have one selected already when they display. Basicly all of them would display unselected.

Public Class Form2
    Dim ttl As Integer
    Dim Tstring(5) As String
    Dim answer As String = ""

    Public Sub New(ByVal totalvar As Integer, ByVal txtstr() As String)
        InitializeComponent()

        ttl = totalvar
        Tstring = txtstr

    End Sub

    Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim radioarray(5) As RadioButton

        radioarray(0) = RadioButton1
        radioarray(1) = RadioButton2
        radioarray(2) = RadioButton3
        radioarray(3) = RadioButton4
        radioarray(4) = RadioButton5


        For count As Integer = 0 To 4
            radioarray(count).Visible = False
        Next
        For count As Integer = 0 To ttl
            radioarray(count).Text = Tstring(count)
            radioarray(count).Visible = True

        Next
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If RadioButton1.Checked = True Then
            answer = RadioButton1.Text
        ElseIf RadioButton2.Checked = True Then
            answer = RadioButton2.Text
        ElseIf RadioButton3.Checked = True Then
            answer = RadioButton3.Text
        ElseIf RadioButton4.Checked = True Then
            answer = RadioButton4.Text
        ElseIf RadioButton5.Checked = True Then
            answer = RadioButton5.Text
        End If

        Label1.Text = answer
        Debug.WriteLine(answer)
        Me.Close()

    End Sub
End Class

The idea behind RadioButtons is that one is always selected, but you can set the Checkstate of all radio buttons to be False in the designer.

Incidentally you can do this;

        If RadioButton1.Checked Then
            answer = RadioButton1.Text

you dont need RadioButton1.Checked = True.

[hockey1314]

The checked state was set to false in all of my radio buttons. So does it always still have to have 1 checked by default. And that is why it is showing?

Thanks for the tip about not needing = true.

[Bulldog]

That would be normal.

[Bulldog]

If you wanted that functionality, you could use CheckBoxes instead.

[hockey1314]

not a big deal just an anoyance.

Thanks for your help.

[Bulldog]

If you put four checkboxes down, you can do handle the events so that only one is ever checked, but they can all be un-checked.

There's probably a more compact way of doing this, but this what I mean;

   Private Sub CheckBox6_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox6.CheckedChanged
        If CheckBox6.Checked Then
            CheckBox3.Checked = False
            CheckBox4.Checked = False
            CheckBox5.Checked = False
        End If
    End Sub
    Private Sub CheckBox5_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox5.CheckedChanged
        If CheckBox5.Checked Then
            CheckBox3.Checked = False
            CheckBox4.Checked = False
            CheckBox6.Checked = False
        End If
    End Sub
    Private Sub CheckBox4_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox4.CheckedChanged
        If CheckBox4.Checked Then
            CheckBox3.Checked = False
            CheckBox5.Checked = False
            CheckBox6.Checked = False
        End If
    End Sub
    Private Sub CheckBox3_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox3.CheckedChanged
        If CheckBox3.Checked Then
            CheckBox4.Checked = False
            CheckBox5.Checked = False
            CheckBox6.Checked = False
        End If
    End Sub
