Not embedded within IE control which is in a winforms control, no. The mediaplayer is hosted just within the app. But remember, due to the nature of the transparency of the borders, etc. (odd shaped windows form), THAT portion cannot operate as touchless deployment either (or as Mark always called it "dynamic winforms").
Although I would like to see how you got the AxHosted media control through the security? That would be interesting to review.
Aside from this though, you wrote this
"If you read the linked page, it states that ActiveX controls that are yet installed will invoke the information bar."
What do you mean by those that are 'yet installed'?
- Also very funny: I'm a former MS employee myself.

I don't have access to that code anymore (I no longer work for that company), but since our application was so large and required just about every permission I created an installer that added a code group (using a UrlMembershipCondition) that required the FullTrust permission set. Hosting the WebBrowser control was no different than hosting it in a locally launched Windows Forms application.
"Yet" installed means the ActiveX control (and related libs, etc.) haven't been installed yet. I.e., you install a fresh copy of Windows. You don't have QuickTime (I'd love to go without that resource hog, but unfortunately can't due to people actually distro'ing QT content!), Flash, etc. When you go to a page that requires them (assuming they have the right codebase), you'll get the bar in IE (with XP SP2). They haven't been installed yet.

Well, I do now have the activeX control showing the picture on the webpage without a warning, HOWEVER, if I script ANYTHING to it (even just getting a true / false property value) it triggers the stupid SP2 stuff.
So here's my question: CAN I through javascript detect if this object exists? I know I can do a Javascript attempt such as
var myClient = new ActiveXObject("Project.ClassName");
within a try catch, however even though this OCX is SIGNED, it says that it cannot create the object? Although putting the OBJECT tag with the classid shows up just fine.
Is this more SP2 B.S.?

You have to mark your ActiveX control "safe for scripting". This really isn't anything new in XP SP2, though. IE always acted this way when scripting ActiveX controls, but reacts a little different now (i.e., how it interacts with the user). I suggest reading about IE security zones and settings in MSDN Library.
Most of this comes down to the user's security settings. You can't get around them (knock on wood), otherwise what's the point of security? You have to work within them and utilize what you can.
If you want to use javascript to see if an object exists, there's always typeof you can use like so:
if (typeof("myControl") == "object") window.alert("It exists!");The fact that your ActiveX control is signed will 1) dictate what the user sees and how confident they should be (a nicer UI for signed components), and 2) the different security zone settings for signed and unsigned components, as well as signed and unsigned .NET Components (when the .NET Framework is installed).
I also urge you to explore the security zones settings if you haven't already. Be sure to set them all to default (click the "Default" button after selecting each one) at first to get a glimpse of what you're dealing with.

I coding one programm:
private void button1_Click(object sender, System.EventArgs e)
{
thread = new Thread(new ThreadStart(ThreadFunc));
thread.Start();
}
public void ThreadFunc()
{
try
{
tcpListener = new TcpListener(IPAddress.Any, 8080) ;
tcpListener.Start ( ) ;
while (bConnect)
{
if (tcpListener != null)
{
m_socket = tcpListener.AcceptSocket();
if(m_socket.Connected)
{
Thread thread1 =new Thread(new ThreadStart(Receive));
thread1.Start();
}
}
}
}
catch(Exception exp)
{
MessageBox.Show(exp.Message);
}
}
protected void Receive()
{
int iRead = 0;
byte[] bts = new byte[1024];
while (true)
{
iRead = m_socket.Receive(bts);
if (iRead == 0) break;
byte[] btRead = new byte[iRead];
Array.Copy(bts, 0, btRead, 0, iRead);
string sTemp = Encoding.Default.GetString(btRead);
listBox1.Items.Add(sTemp);
}
}
private void button2_Click(object sender, System.EventArgs e)
{
this.bConnect = false;
}
private void button3_Click(object sender, System.EventArgs e)
{
DoSomething();
}
I want to dosomething when click button3. It can stop the listener, and exit the thread. but I get a same result, the programm can't close normally.

I do a socket server, When I click button1 then throw one thread that it listen host port. If some data receive from remote host, then throw another thread that receive data. If I click button2, I want to close port and stop the listen thread , but I find it always fail.
yesterday, I found out If want to stop the listen port and thread, when I click the close button, send some data to server port then it can close normally.
But I want to know one better method.

Hi!
I just wanted to ask about the dlls that we add to the application folder using the setup projects, are they registered on installation and if yes why. The reason that i ask this is that my project required mfc70.dll for it to work, i added mfc70.dll in the application folder and now when i install the application using the installer, there is an error saying:
"Module C:\......\mfc70.dll failed to register HRESULT -2147024769 Contact your support personnel" and it gives me 3 options, "Exit installation", "try again" or "continue."
Please help me out here.
Thanks.

hi,
try to add through the reference folder which is avilable in your application.

Please clarify what do u mean by the reference folder, do u mean the folder which is present along with the installer while building from which installer program picks up the files and creates the MSI. If yes, then i did add the dlls from that folder, actually all other dlls work fine, its just a problem with mfc70.dll.
Thanks for the prompt reply.

I add all the files, whether dlls or other files to a folder named "Application" and keep it in the same directory as the setup project. Then in the setup project, i add the files to the application folder, by right clicking on the Application Folder->Add->File and then browse to the Application folder and add the mfc70.dll and other files from there. Am i doing something wrong? I have also made a hierarchy of folders inside application folder, and i add the files to the folders with the same method.
Thanks for your response.

If you see a your solution explorer you can see a References(lite brown color) folder. Please try to add your file in that folder.
Right Click and choose Add reference option. then try to browse the location of your .dll file( c:\winnt\system32) and click on open button.
Then tell me it is added properly or give you any error message.

You do not include MFC. You use a merge module for that, and it should never be registered from a directory other than the [SystemFolder]. Merge modules take care of this for you.
Besides, mfc70.dll - or any MFC library - does not export DllRegisterServer so it is not registerable.
System DLLs should only be added via merge modules, and just about all of them are. This makes sure that DLLs are installed and uninstalled (if applicable) correctly.

Take a look at the Application class which provides some static methods to retrieve the information you want.
