I went thru that. I have implemented the following similar code in my application:
private void SystemEvents_PowerModeChanged(object sender, Microsoft.Win32.PowerModeChangedEventArgs e)
{
//The system is going into or resuming from standby
if (e.Mode == Microsoft.Win32.PowerModes.Suspend)
{
mLog.Info("System is going into standby, FST must shutdown");
clsMessageBroker.Shutdown();

}
else if (e.Mode == Microsoft.Win32.PowerModes.Resume)
{
mLog.Info("System is resuming from standby");

}
But this is not helping. I doubt the autodetect has got to do soemthing with the problem. It has a lot of handlers called thru the wndprc method, but i'm not sure how they r getting closed or which of htem is throwing the exception which is leading to the crash.

Thanks so much! The application in the below link works great! but I'm looking for a similar one in C#. Or do you any work around ?

Hi Espen, thanks for the input. The VISTA system has .net f/w 3.5 sp1 installed.
However I found out that the method asdataview is supported in VISTA sp1 or later.
I want to know if there is a work around for VISTA with versions previous to SP1.

EnumerableRowCollection<devicevariablesdataset.devicevariablelistrow> query =
from rows in mVariableList.AsEnumerable()
where rows.Monitored == true
orderby rows.VariableName
select rows;

mSelectedVariablesLock.EnterWriteLock();
try
{
mSelectedVariables = query.AsDataView();// throwing exception
}
finally
{
mSelectedVariablesLock.ExitWriteLock();
}

this is the codepiece

EnumerableRowCollection<devicevariablesdataset.devicevariablelistrow> query =
from rows in mVariableList.AsEnumerable()
where rows.Monitored == true
orderby rows.VariableName
select rows;

mSelectedVariablesLock.EnterWriteLock();
try
{
mSelectedVariables = query.AsDataView();// throwing exception
}
finally
{
mSelectedVariablesLock.ExitWriteLock();
}

Please find the error details as below : System.TypeLoadException was unhandled Method 'FindByKey' on type 'System.Data.LinqDataView' from assembly 'System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is overriding a method that is not visible from that assembly. at System.Data.DataTableExtensions.AsDataView[T](EnumerableRowCollection`1 source) at IRst_VariableSelectorUIExtension.frmVariableSelector.BeginLoadDataMap(String fileName) in D:\Service Tool_SCM\Source_latest\IRst_VariableSelectorUIExtension\frmVariableSelector.cs:line 920 at System.Runtime.Remoting.Messaging.StackBuilderSink._PrivateProcessMessage(IntPtr md, Object[] args, Object server, Int32 methodPtr, Boolean fExecuteInContext, Object[]& outArgs) at System.Runtime.Remoting.Messaging.StackBuilderSink.PrivateProcessMessage(RuntimeMethodHandle md, Object[] args, Object server, Int32 methodPtr, Boolean fExecuteInContext, Object[]& outArgs) at System.Runtime.Remoting.Messaging.StackBuilderSink.AsyncProcessMessage(IMessage msg, IMessageSink replySink) Many Thanks, Vidya
