RE: Autosizing and column spanning conundrum

2008-07-24T21:32:01Z

Thanks for validating the issue. Though you say you believe it is by design,
you also seem to agree with me that the behavior is faulty... Just wanted to
let you know that I have therefore submitted this as a product issue in

Re: socket packet size = bandwidth?

2008-07-24T21:24:51Z

Yes, that's correct. The only real downside for the larger buffer is the
memory consumption locally. Generally speaking, larger buffers provided
to the Socket _improve_ performance, because you have to transition back
and forth between your application code and the network driver fewer
times. Of course, beyond a certain point (16K is a good number) you get

Re: socket packet size = bandwidth?

LOL
Sorry, I meant receiving 5 bytes. Most of my bandwidth is receiving
data, so this is the important part.
(I use Socket.Send(), obviously, to send data, and that takes an array
of byte, byte [], and I make that whatever size it needs to be at the
time, so I assume that this only uses as much bandwidth as is required

I added the symbols for the .NET Framework and stepped down through
the code. The final call made is:
SafeNativeMethods.UpdateWindow (new HandleRef(window,
InternalHandle));
which is the only line of code in the ControlUpdate method shown in
the top of the Call Stack.

Re: socket packet size = bandwidth?

2008-07-24T20:54:35Z

All due respect, it is at the very least poorly worded. :)
If you are asking a question that involves calling Socket.BeginReceive(),
why is your hypothetical case described as "I send a 5 byte 'hello'"? Are
you asking about sending, or about receiving? And is the question about a
UDP socket or TCP socket?

Re: Help with the difference between "Implements" and "Inherits"

2008-07-24T20:53:30Z

The first only inherit the interface. The second inherit
only the interface and the implementation.
But I would be careful with the second - it is easy to
become coupled with the internals of List.

For simple to intermediate games then C# would be an excellent choice.
I believe there game toolkits available.
For the most advanced games, then I think they will continue to
use C/C++.
The usage of C/C++ is to some extent historic determined. But
the real advanced games some of the parts especially for graphics

Hi Rainer,
You may be able to improve your situation somewhat by booting with the 3GB
switch and setting the LARGEADDRESSAWARE flag on your exe, but the best
solution is to install a 64 bit OS

Re: C# optimized code prevents debugging

2008-07-24T20:39:14Z

Nope, it's because the code is optimized by the compiler, and the
debugger doesn't know where the values are that you want to look at.
Run the same code with "optimize code", and you'll see everything you
want to see.

Re: C# optimized code prevents debugging

2008-07-24T20:37:56Z

Yes.
I understand. But, it appears that this 'simplified' project settings
for Express editions make clear decisions based on Release or Debug,
meaning that they are not just labels -- not in this context. The
settings specifically apply to one or both. It's too bad it doesn't
tell you which. :)

DataGridView refresh causes "Not Responding" application (but only when not in Visual Studio)

2008-07-24T20:26:51Z

Ok, extremely wierd situation here:
(I'll post the code below, after the explanation)
I've got a Windows application (.NET 3.5) that has a single Form with
a DataGridView embedded. The user presses a button to do a SQL query
(fill a DataSet). Before firing the query, I disable the grid/buttons
and turn on UseWaitCursor. After it completes, I re-enable the grid/

Re: C# optimized code prevents debugging

2008-07-24T20:23:26Z

Interesting. It's often the case that making things simpler for some
people makes them more complicated (and less predictable) for others :(
Because "Debug" is just an arbitrary label, I believe. There's nothing
really magical about Debug and Release as build configurations, as far
as I know. You can create your own, call them what you want and tweak
