Bill, thanks I ended up using http://blogs.msdn.com/b/pfxteam/archive/2012/04/13/10293638.aspx

under the sections avoid unnecessary marshalling and offloading to another thread.

No I set it to something like "/images/resize/test.png" where the images folder is a subfolder of the directory it is running from.

Yeah, that is a good idea. Unfortunately, I have the clients update themselves every 1.5 seconds, so I can't look at it in the browser's tools before the update happens. Perhaps there is a way in Chrome or IE to make the page stop updating itself through the page's timer?

Thanks.

I ended up doing exactly what you suggested before I saw your response.

Dave, that isn't entirely true. We have an ASP.NET application that does get the MAC address of a browser client on the same network as the server. However, as you say, you can't get it directly.

The way to do it is to get the IP address of the client, then look up the MAC address in the ARP cache on the server.

That worked perfectly for me.... Thank you very much!

DeleteSheet represents a method that is called. They all have different functionality, but all return a bool. Should I use a delegate for this and pass the delegate to the generic method?

David Knechtges 20-Dec-13 11:28am View

Griff,

The Delete method executes different code, based on what function it is, but they all return bools. How can I handle that? Use a delegate for this?

Yes it is right IF the data coming back from the database does not include the "-->" at the beginning of the string. Maybe it is his question that is unclear to me. I thought his database was sending back "-->1234-567-89" and he wanted "-->123456789", which in the solution I posted below is correct.

David Knechtges 6-Sep-13 9:08am View

That won't work - he has 2 dashes at the beginning of the string.

Now I am curious - it appears you are doing the right things, but the receiving app is not. I know you are a really experienced programmer from reading your articles, so I am going to suggest that you try this now:

Try writing a quick sample app in unmanaged code doing the exact same thing you are doing in C#. See that the receiving app sends back the information you want. My guess is that it may not. You can also then experiment with different types of memory to send it to the app also if the first way you try does not work.

I have done this in the past in order to figure out the way to get something like this to work in the way that I wanted.

Thanks for the tip. My comment above was meant to be done in your GetMessageText function. Copy the bytes from the IntPtr, and see what you get.

David Knechtges 3-Feb-11 10:38am View

How about copying the data to a byte array and then converting it? That would show you if the array of unmanaged bytes is coming across correctly, and then you could use the managed stuff to convert it to a string.

Like using the Copy(IntPtr, Byte[], Int32, Int32) overload.
