Internet speed is usually refered to as the downstream bandwith, iow the download speed, unless u specify bith upstream and downstream rates.

It is never the sum of both. That would be the maximum throughput of the device.

Hope this helps Smile | :)

Would anybody know how to do an update from a datagrid in ASP/C#?

I have it all the way to the update command, but can't find and good tutorials to Get it any further. I'm going to need to do a SQL statement, but I don't know how to GET the values back from the Grid.

In all seriousness, dump windows 98/ME and move to 2000/XP Pro.

OK, I have been play with this on and off all day and can not make it work.

How do I define an instance of of a performance counter at runtime?

I have the counter defined in the server explorer and can use the counter it's self, but I wish to add intances of the counter, in the same way as, for example, 'Processor/% Idle Time' has.

Anyone any ideas?

Thanks

Stephen

Drag it from the Server Explorer onto your form. That will give you a control to work with.

I can get a normal performance counter to work no problem, what I cant get to work is the InstanceName property.

If I try to access one of the existing performance counters that has multible instances that works, but I can not create my own.

Bassically I have this system that can load plug-in modules at run time. I have a custom counter called 'Messages Dispatched' now under that I want to create an instance for each plugin i.e. 'E-Mail', 'SMS' etc, just like under PRocessors you can see an instance of each processor.

The documentation said to pass the instance name in the constructor to ProcessCount but that does not work for me. The app starts and perfmon shows no instances, just the root performance count.

Thanks

Stephen.

Yeah but that shows how to use it from C#. Not how to implement it in C#. Frown | :(

Not quite true. C# supports the params keyword, which allows an object[] of user-defined size to be passed as a method parameter. This could be used to implement optional args in a sense.

i suppose, but not in the same manner as in c++ which i think is better.

Those are the key words right there.... Instead of writing a normal method and specifying default values you have to go through the array and find out which parameters go where, and lord help you if you have two parameters of the same type but only one is in the array WTF | :WTF:

There are times where I like not having optional parameters because it makes the user of that code think before just accepting the defaults; other times its a real PITA.
