| How to maintain order in a grid with three row types. Brady Kelly 13:32:07 |
| | I've probably just been looking at this too long, but would like some input
please. I have a DataGridView that presents reporting bands. Each band may
or may not have a header or a footer, so I use a rowType var that guarantees
the header-band detail-footer will always remain in sequence, but I now
worry about inserts and deletes, where any one of the three, or all three,
may be deleted. Insertions are also causing a brain freeze today.

| Erratic Masterpage cast exception Mark Aurit 00:57:07 |
| | I have a masterpage named MasterpageController with a menu. In the
codebehind I have a method SetMasterMenu(<some parms>) to display the
appropriate menu items.
The content page, which has a MasterType directive, executes the method
using "this.Master.SetMasterMenu(<some parms>)". Runs fine for maybe 5-10
"start with/without debugging"'s, while I am in development mode in
vs.net 2005, and then I'll start getting an "Unable to cast object of type
'ASP.masterpagecontroller_master' to type
'ASP.masterpagecontroller_master'" when the content page attempts to
execute the method. I have to restart IIS
to get the app to run correctly .. then a few starts later I get the
exception.
I havent seen this behavior when I publish the app onto a staging
server, just on my development laptop.
Any ideas on how to fix this? Does it only happen while in development,
not in a published site?
Thanks, Mark

| Allowing a method to timeout Amit Bhatnagar 20:18:55 |
| | Hi All.
I am finding that my win32 call to SystemParametersInfo in my
FormClosing event handler sometimes hangs my application preventing it
from terminating. Is there a way where I could make the call but after a
timeout period then continue executing the rest of my FormClosing code?
Place this in a thread? I'd like to make the solution generic enough so
that I could timeout any method.
Any ideas?

Try the command "mode com1" (or what ever com port you use) in a cmd shell.
What settings are returned? Do they match the settings you want to use from

you meant?

Thanks, Don. I have a very small test c# (2.0) app that opens a serial
port, sets the baud rate and a few other items, and then writes a stream of
50 chars. Doesn't seem to present a problem. I have a much larger, more
complicated c# app that also writes to a serial port with similar port
settings and less characters and I keep getting a write timeout error. So
it doesn't seem to be the hardware. I am looking for other places I might
have screwed up (and yes, I do know the port is open!  .

It's not always just the length of the data and the baud rate. I've seen
write timeouts happen when using virtual serial port controls even though
given the baud rate and the length of the data there was ample time to
complete the operation. The most recent drivers for the siLabs 210x USB to
Serial chips seem to be especially slow. With a write timeout of 400ms I was
sometimes unable to write 2 characters to my device at 38400 baud.
If the write operation isn't completed during the timeout period a
timeoutexception will be thrown.

I have been searching for info on what actually will cause a WriteTimeout
error to happen on a serialport object in net 2.0. There are lots of
articles that talk about a Write operation not being able to complete in the
time allotted. However, besides having a series of bytes to be written that
when taking into the account the baud rate cannot complete in the allotted
time, I can't think of another reason for this error to occur - nor can I
find reference to when it will occur.
Any ideas or places you could point me, please?

| TCP Queue (Backlog) Gavin Landon 11:11:42 |
| | Morning all..
I'm having an issue that I've spent a few days on. I'm building a web server and when I stress tested the server I got great results, but with one bad one.. I'm getting a lot of socket errors. I have the following, but this doesn't seem to be working list expected..
IPAddress inputDNS_IP = Dns.GetHostEntry(this.m_szHost).AddressList[0];
this.svrListener = new TcpListener(inputDNS_IP, this.m_lPort);
//setup timeouts..
this.svrListener.Server.ReceiveTimeout = 30000;
this.svrListener.Server.SendTimeout = 30000;
//start with a backlog "TCP/IP Queue" of 1024
this.svrListener.Start(1024);
I've changed the backlog param in Start() from 1 to 4096 and no matter what the value it doesn't seem to queue up the TCP message like expected. Am I missing something?

Does anyone know of any?

| Windows\App shut down? (OT?) Peter Osucha 00:13:28 |
| | Hi all,
This probably isn't the appropriate place to ask this question - my
apologies in advance. I hope someone might suggest a more appropriate
place to ask this...
I have a windows app running on a machine. If a user goes to
Start-->Shut Down to shut down the system, what can I expect to happen
to my app as far as it shutting down? Does it just get a hard 'END'
message or is the shut down of the app more controlled? App is in C#
for net 2.0...
Thanks,
Peter

| Passing property Accesor as Function` Brady Kelly 01:55:09 |
| | Warning: This is a purely academic and speculative post.
This has suddenly become a real 'would like to have' feature in the project
I'm currently working on. I know this isn't possible in standard C#, but
I'm trying to find a hammer with the right weight and shape to beat this
into some semblance of working. What I would like to achieve is something
like this, in the commented line:
public class PersonForm
{
System.Windows.Forms.TextBox textRate = new TextBox();
public void BuildPerson(Person person)
{
Person pers = new Person();
pers.HourlyRate = textRate.Text.Length == 0 ? (double?) null :
double.Parse(textRate.Text);
// SetPropertyFromText(pers.HourlyRate, textRate.Text)
}
}
My SetPropertyFromText should take the pers.HourlyRate as a delegate
parameter, not as a double?, determine the correct type conversion based on
the type of the pers.HourlyRate, and set the property to the converted
object value.
I can easily use a property name as my property parameter for
SetPropertyFromText, but then I lose compile time checks. Our generated
DAL, nettiers, provides, for each entity, an Enum with all the column
properties for each entity, and I think this is about as close as I've seen
to what I want, but not quite there.
Any ideas on the matter?

| Is it safe to have a mixed-mode DLL serve out COM objects? Gyorgy Bozoki 07:57:08 |
| | Hi all,
I'm working on a mixed-mode DLL in C++ that calls into managed code,
implemented in C#. As it turnes out, the 3rd-party application that I need
to talk to provides some of its functionality through COM interfaces - I
need to implement some of those interfaces on my objects in C++ code.
As I'd prefer to have as few DLLs as possible (my objects will be inproc
servers), I'd like to use the mixed-mode DLL to serve out the COM objects
implementing these interfaces.
Is there anything wrong with this approach? I don't see anything wrong about
it, but it's been a while since I wrote COM code and never before in
mixed-mode.
Thanks for any advice,
Gyorgy Bozoki

| Calling C# from C++... Gyorgy Bozoki 09:07:27 |
| | Hi all,
I have a problem and I was wondering if someone could give me some advice.
I have a 3rd-party application to which I'm creating a plugin. The plugin
must be a plain Win32 DLL that exports several functions by ordinal. I'll
have to implement the DLL in C/C++, because of memory allocation
requirements - doing this in C# would be very cumbersome.
I also have another DLL written in C# that exposes a few classes and
dialogs, so that users of this DLL can pass some data to these dialogs and
show them on the screen to the user. The DLL is already complete and is used
in several places (all .Net, so far), so I cannot change it in any way.
What I need to do is to use this same C# DLL from my first DLL, which is
written in C++. I know both C++ and C#, but I don't know much about interop
between the two. What would be the best approach to write the C++ DLL so
that it can talk to both the unmanaged 3rd-party app and my managed DLL?
Thanks in advance,
Gyorgy Bozoki
