Summary: Mono crashes in runtime while creating and accessing
dynamic controls e.g. buttons
Product: Mono: Runtime
Version: 2.0
Platform: x86
OS/Version: Windows XP
Status: NEW
Severity: Critical
Priority: P5 - None
Component: JIT
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
QAContact: [email protected]
Found By: Development
The following code demonstrates that mono crashes when trying to access a
button text that was created dynamically.
The same code running without the mono execution in .NET is executing perfectly
and the button text is appearing correctly. I am attaching a VB code the
replicates the problem. The code was written and compiled in VisualStudio 2008.
(two buttons are attached in a Form: Button1 and btnTest). The sender argument
does not deliver the text correctly when in Mono running mode.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
MessageBox.Show(sender.text)
End Sub
Private Function AddButton(ByVal Text As String) As Button
Dim btnNew As New Button
Static iCount As Integer = 1
Dim btn As Button
btn = Button1
btnNew.Left = btn.Left + iCount * (btn.Width + 10)
btnNew.Top = btn.Top
btnNew.Width = btn.Width
btnNew.Height = btn.Height
btnNew.Text = Text
AddHandler btnNew.Click, AddressOf Button1_Click
iCount += 1
Return (btnNew)
End Function
Private Sub btnTest_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnTest.Click
Me.Controls.Add(AddButton("One"))
Me.Controls.Add(AddButton("Two"))
Me.Controls.Add(AddButton("Three"))
End Sub
End Class
