MsgBox always return "no" regardless of what the user click

The following seems to work just fine.....

Can you provide some more code around how your using this, console, windows application and does this occur in all projects you create or just this one.

You know that you can leave off the Bold item as msgbox is part of the core language.

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If Microsoft.VisualBasic.MsgBox("Do you want to save your changes", MsgBoxStyle.YesNo) = MsgBoxResult.No Then
Me.Button1.Text = "No"
Else

Me.Button1.Text = "Yes"
End If
End Sub

End Class

Is there anything about this machine we should know - did it have a beta of visual studio installed, or a previous version of visual studio 2003

Thank you for your response. I have a windows application. The issue does not occur in other projects, and as a matter of fact, I use the exact same code other places in my application and it works fine. Its just in this one event handler. Enclosed is the complete code:

Private Sub RepositoryItemLookUpEdit1_EditValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RepositoryItemLookUpEdit1.EditValueChanged

'

' Declare local variables

'

Dim objPart As Parts

Dim objPartRev As PartRevs

Dim objTemplate As Templates

Dim cm As CurrencyManager

Dim response As MsgBoxResult

Dim intResponse As Integer

'

' Get the current PartRev we are working with

'

If objPart Is Nothing Then Exit Sub 'No Part object

If objPartRev Is Nothing Then Exit Sub 'No PartRev

'

' Get the currency manager for the objParts collection now so we can refresh it later

'

'

' If there is already a Process prompt to overwrite it first

'

If Not objPartRev.ProcessItems Is Nothing Then

If objPartRev.ProcessItems.Count > 0 Then

'Microsoft.VisualBasic.MsgBox("You are about to overwrite the existing process.", MsgBoxStyle.Information, "ShopTrack")

response = Microsoft.VisualBasic.MsgBox("Are you sure you want to overwrite the existing process?", MsgBoxStyle.YesNo, "ShopTrack")

If response = MsgBoxResult.No Then

Exit Sub

End If

End If

End If

'

' Get the ProcessTemplate Selected

'

objTemplate = RepositoryItemLookUpEdit1.GetDataSourceRowByKeyValue(CType(sender, DevExpress.XtraEditors.BaseEdit).EditValue)

'

' Call the shared method to remove the old process and add the new process from the template (objPartRev passed by reference)

'

'

' Mark the part as changed now

'

'

' Refresh the CurrencyManager now

'

'

' Done

'

End Sub

I am using DevExpress controls, but again this does not happen with other event handlers, even of the same class. DexExpress support has no idea either.

Any help would be greatly appreciated!

Thanks,

Susan

I'll just give something in here! If you want to you can use something like the following, which i have used in all my applications:

If MsgBox("Question Here", [yesno option], "title") = # then

else

end if

The following values are what you would use for the # (number ):

Yes = 6

No = 7

Cancel = 2 (when using yesnocancel option)

If you want to do it a bit differently set the answer to a string and test the string!

Also you dont by any chance happen to have mcafee antivrius software on this machine.

This has been creating numerous problems with messagebox functionality.

I am using McAfee Internet Security Suite 8. I disabled all services and re-ran my tests with the same result. The really wierd part is that this code works elsewhere in my code, it's just in this event handler.

Thanks,

The following thread indicates there is a patch for mcafee which you should look at - The mcafee antivirus has been causing a number of problems with the Messagebox functionality.

That is the correct behavior. The resturn value of an MessageBox (or any other Dialog for that matter) is not a boolean value, but a System.Windows.Forms.DialogResult Enum member (http://msdn2.microsoft.com/en-us/library/system.windows.forms.dialogresult.aspx).

A messagebox can return other values than yes/no (Abort, Retry, Cancel, Ignore, OK)

So you should always compare the value with the enum value
