MesageBox Show only accepts two arguments, but I need a third argument

Question

I need to have a confirmation dialog box by showing MessageBox.Show("Caption", "Title", MessageBoxDialog), but an error occurred "Error 1 Overload resolution failed because no accessible 'Show' accepts this number of arguments"

Already tried to check some other codes in the internet, but its always with the same error.

This was copied from dotnetperls.com

`   Dim result1 As DialogResult = MessageBox.Show("Is Dot Net Perls awesome?", "Important Question", MessageBoxButtons.YesNo)`

and this one is currently in my code, copied from MessageBox with YesNoCancel - No & Cancel triggers same event

 `Dim result As Integer = MessageBox.Show("message", "caption", MessageBoxButtons.YesNoCancel)
    If result = DialogResult.Cancel Then
        MessageBox.Show("Cancel pressed")
    ElseIf result = DialogResult.No Then
        MessageBox.Show("No pressed")
    ElseIf result = DialogResult.Yes Then
        MessageBox.Show("Yes pressed")
    End If`

I suspect that you have a class in your project named `MessageBox`. That will take precedence over types with the same name in referenced assemblies. Either change that name or qualifying the other type in your code. — jmcilhinney, Oct 04 '19 at 11:26
I'd suggest using a `Select Case` in that code. It will be more succinct than `If...ElseIf`. — jmcilhinney, Oct 04 '19 at 11:27
Try using it like this `System.Windows.Forms.MessqgeBox.Show()` — preciousbetine, Oct 04 '19 at 13:18
if you want another argument, you've come to the right place =) — Ess Kay, Oct 04 '19 at 18:48
also, remove the `.show` just `msgbox("1","2",MessageBoxButtons.YesNoCancel)` — Ess Kay, Oct 04 '19 at 18:49
@EssKay No, that won't compile. You are mixing Apples and Oranges. — Mary, Oct 04 '19 at 20:57
@Mary thanks stalker :) Seems my memory was off and you were correct. My answer should reflect that — Ess Kay, Oct 07 '19 at 13:07

From my previous code which I thought I lost:

If confirm = MsgBoxResult.Yes Then Dim reConfirm As MsgBoxResult = MsgBox("YOU ARE REALLY SURE?", MsgBoxStyle.YesNo) If reConfirm = MsgBoxResult.Yes Then End If End If

Variant 1


Dim result = MsgBox("Message" , MsgBoxStyle.YesNoCancel, "Caption")
Select Case result
    Case MsgBoxResult.Yes
      MsgBox("Yes pressed")   
    Case MsgBoxResult.No
      MsgBox("No pressed")   
    Case MsgBoxResult.Cancel
      MsgBox("Cancel pressed")   
End Select

Variant 2

Dim result = MessageBox.Show("Message", "Caption", MessageBoxButtons.YesNoCancel)
If result = DialogResult.Cancel Then
    MessageBox.Show("Cancel pressed")    
ElseIf result = DialogResult.No Then
    MessageBox.Show("No pressed")    
Else
    MessageBox.Show("Yes pressed")    
End If
