Hi,

I'm currently having a problem for which I haven't foud a solution.
I've got a winform application (C#, .NET 1.1) which should work correctly on
Vista (currently Beta 2).

I'm trying to do a send key but it does crash when the OS is Vista (It works
fine on Windows XP and lower).

Here is the line of code which crashes :
SendKeys.SendWait("^(c)");

Here is the exception :
Error details:-
======== Exception Information ========
System.Security.SecurityException: Requested registry access is not allowed.
   at System.ThrowHelper.ThrowSecurityException(ExceptionResource resource)
   at Microsoft.Win32.RegistryKey.OpenSubKey(String name, Boolean writable)
   at SYSTRAN.GUI.IEPlugin.IEPluginContextMenu.CleanContextMenu()
   at SYSTRAN.GUI.IEPlugin.IEPluginContextMenu.RegisterContextMenu()
The Zone of the assembly that failed was:
MyComputer

I've looked for information on Internet but I have found no solution related
to this particular issue.

I have tried to change security level for my assembly :
[assembly:UIPermissionAttribute(SecurityAction.RequestMinimum,                 
Clipboard=UIPermissionClipboard.AllClipboard)]

And also that :
// Create a new application domain.
AppDomain domain = AppDomain.CurrentDomain;      
// Create a new AppDomain PolicyLevel.
PolicyLevel polLevel = PolicyLevel.CreateAppDomainLevel();
// Create a new unrestricted permission set.
PermissionSet permSet = new PermissionSet(PermissionState.Unrestricted);
UIPermission perm = new UIPermission(UIPermissionClipboard.AllClipboard);
permSet.AddPermission(perm);
// Give the policy level's root code group a new policy statement based
// on the new permission set.
polLevel.RootCodeGroup.PolicyStatement = new PolicyStatement(permSet);
// Give the new policy level to the application domain.
domain.SetAppDomainPolicy(polLevel);

And in both cases, nothing changed ... I do still have the same error.
It's most probably a problem with the security in Vista where my application
isn't allowed to interact with the desktop. The solution may eventually be to
adjust some security properties on Vista, but but even by changing the
Runtime Security Policy of my assembly nothing changes.

Any idea would be welcomed.

Thanks.

Olivier

I finally found a solution using SendInput API, so I post it, in case someone
may be interested.
