Networking in Virtual PC 2007

It seems pretty straightforward to use Virtual PC 2007. The only problem people might encounter while making a guest Window XP is to setup its network environment. By following the suggestions in this post, I select "Shared Networking(NAT)" and configure to use DHCP in the guest OS. Then everything works and the virtual gateway in the guest OS is always 192.168.131.254.

On the other hand, if I want to connect to the guest OS from the host, I need to select a network adapter for the guest OS and assign an IP address for the adapter in the guest OS. Also, be sure to turn off the firewall in the guest OS. Then the outside machine can access server applications in the guest OS.

Finally, the "Undo Disks" option in the setting is useful, too. If enabled, I can rollback the changes I make to the guest OS since it starts.

Update: Here is a post compiled a list of many useful information about Virtual PC.

ManagedSpy - A Testing Tool For Managed WinForm Applications

ManagedSpy is a tool for access the properties and events of managed windows applications at run time. It's good for debugging or testing Windows Forms controls and is equivalent to Spy++ for unmanaged windows applications.

ManagedSpy is acutally an example demonstrating the usage of ManagedSpyLib. ManagedSpyLib introduced a class, ControlProxy, with which we can get or set properties or subscribe to events of a System.Windows.Forms.Control in another process.

An introduction to ManagedSpy and the internal of ManagedSpyLib can be found in this MSDN article. The following is a testing program listed in the article for testing a WinForm application which has 2 textboxes accepting 2 integers and one button which multiply the 2 integers and shows the product in a third textobx. The lines of code in the blue color use the methods of ControlProxy. As you can see, the testing program programmatically accesses the three textbox controls and one button control in another WinForm program.

private void button1_Click(object sender, EventArgs e)
{
Process[] procs = Process.GetProcessesByName("Multiply");
if (procs.Length != 1) return;
ControlProxy proxy =
ControlProxy.FromHandle(procs[0].MainWindowHandle);
if (proxy == null) return;

//find the controls we are interested in...
if (cbutton1 == null)
{
foreach (ControlProxy child in proxy.Children)
{
 if (child.GetComponentName() == "textBox1") {
     textBox1 = child;
 }
 else if (child.GetComponentName() == "textBox2") {
     textBox2 = child;
 }
 else if (child.GetComponentName() == "textBox3") {
     textBox3 = child;
 }
 else if (child.GetComponentName() == "button1") {
     cbutton1 = child;
 }
}

//sync testchanged on textbox3 so we can tell if it has changed.
       textBox1.SetValue("Text", "5");
       textBox2.SetValue("Text", "7");
       textBox3.SetValue("Text", "");
       textBox3.EventFired +=
           new ControlProxyEventHandler(textBox3_EventFired);
       textBox3.SubscribeEvent("TextChanged");
}
else textBox3.SetValue("Text", "");

//now click on the button to start the test...
if (cbutton1 != null)
{
       cbutton1.SendMessage(WM_LBUTTONDOWN, IntPtr.Zero, IntPtr.Zero);
       cbutton1.SendMessage(WM_LBUTTONUP, IntPtr.Zero, IntPtr.Zero);
   Application.DoEvents();
}

if (result == 35) MessageBox.Show("Passed!");
else MessageBox.Show("Fail!");
}

void textBox3_EventFired(object sender, ProxyEventArgs ed)
{
int val;
if (int.TryParse((string)textBox3.GetValue("Text"), out val)
{
result = val;
}
}
