Hi,
I still have the same problem with embedding Windows Control. I'll just
requote what I posted last time:
[QUOTE START]
I managed to create a Windows Form Control and put it on my ASP .NET page. I
have done the suggestion that is provided by modifying the security settings.
From the stack trace, I would assume that the code throws exception when it
is trying to retrieve the processes list that has certain name. Below is the
code that I use to retrieve the processes.
Process[] processes = Process.GetProcessesByName("xxxx");
The above code is the first line within the method IsProcessRunning() which
is the top on the stack trace.
Could anyone help me on this?
Below is the error that I get:
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

If you guys are curious with the security check, this is what I wrote before
[QUOTE START]
I created a new Permission set that has unrestricted access on all resources
(DNS, Event Log, File IO etc) on Machine Level. After that I created a new
child code group (still at Machine Level) under LocalIntranet_Zone that has
this permission set. After that I called my application through
http://localhost/ActiveXAspTester. Hope that helps.
[QUOTE END]
I have also tried to execute Win32 API from my C# code using EnumProcesses,
OpenProcess, EnumProcessModules and GetModuleFileNameEx, but when I called
EnumProcessModules, somehow they give me error of being Access is Denied (net
helpmsg 5). Is there any other insight how to solve the problem?
Regards,
Budhi
