Hi Again,
i found the PageScale property, and as i understand it changes my page size
(in my case it's 70% smaller).
the problem is that if i use it, it doesn't effect the font size or the
image size that i'm drawing(printing).
is that mean that i have to have 2 different class, one for printing my
document in A4 Size and the second to print it 70% smaller?
thanks,
Gidi.

If you're talking about the Graphics.PageScale property, it doesn't
exactly change your page size. It changes the scaling between "world
coordinates" and "page units". This is probably not exactly what you want
because...

Right, because those things carry with them their own units that are
applied independently. I think that there may be some way to adjust how
those are drawn. However, there's a simpler way. Use the
Graphics.ScaleTransform() method instead. This works similarly to how the
PageScale property does, but should apply equally to _all_ graphics
rendered.

Whether you need two different classes depends on how you've designed your
code. It's entirely possible to design a single class such that it allows
you to specify scaling that's applied when it draws its graphics. Whether
you follow that approach or use two different classes is up to you.

Because C# doesn't support covariance of return types in terms for
interface implementation and member overriding. To override/implement
something, you have to supply exactly the same signature.
It's a pain, but that's the way it is.

I'm afraid that I can't offer anything more than what you have learned
on your own. I only suggested that class because I have seen the
original poster's question many times in various forums and that is,
invariably, the answer that is given. I haven't delved too deeply

Not really, but you can embed WPF in WinForm (via ElementHost) and
WinForm in WPF (via WindowsFormsHost).
However, depending on the complexity, the zooming picturebox (that Chris

Take a look at the System.Net.Sockets namespace.
You could use a TcpListener object to listen for requests from the desktop
application, and a TcpClient (or easier: a WebRequest object) to connect to
the original web server.
However, there might be an easier way: You could use an asp.net application
hosted in IIS to receive the requests from your client. An Http Handler in
your application would process all requests, and use the WebClient class to
send the same requests to the original webserver. This would save you from
programming all the multithreading that you would need to add into your code
if you were using a TcpListener to process mutiple client requests.
You say that you "do not want to create a web service proxy nor do I want to
do anything with web services". However, this route that you don't want to
follow might be the easiest of them all. If all the requests from your
desktop client are calls into a web service, you can probably, with a bit of
work, use asp.net web services to emulate the services in the original
server, and also use the web service client in .Net to call into the server.

Simply move it outside of the method.
For the record, I'd probably use a List<PitureBox> rather than a
PictureBox[] so that I can resize it more easily...

//allocate the picture box

From: DaveC
I am trying to use a ssh stream reader that has no timeout method. It
simply watches the stream until an escape character appears in the
stream. It then returns the contents of the buffer. Thus, when the
server never responds to a read action (no escape character appears in
the stream), the program appears hung while the thread is waiting for
a stream character that never comes.
To solve this, I issue the stream read inside of a 'try' block with a
catch for a custom exception. Just before the call to the stream
reader, I launch a watchdog function with its own thread. The watchdog
sleeps for 3 seconds and then checks the buffer (passed in by
reference) to see if it is still empty. If it is empty, it throws the
customer exception and pulls the main thread back to the catch portion
of the try.
This sounds good, but isn't working. When the exception throws in the
watchdog thread, it is treated like an unhandled exception even tho
the thread was launched from inside of a 'try' that has an explicit
handler for that exception.
In the code snippet below, as part of my efforts to figure this out, I
have the watchdog throw an exception for either condition of the read
stream. If the stream has something in it, one exception is thrown,
and if the stream buffer is still empty another exception is thrown.
Again, both are treated as unhandled even tho the function was launced
with its own thread from inside the 'try' block.
How can I get these exceptions to be handled by the 'try' block catch
blocks?

This is what i noticed in a .net 1.1 app.
you have to try catch within the function that the thread executes. if
you dont have a try catch in the function then you dont get notified
about the unhandled exception.
Dont know if things have changed since then.

An exception can only be caught in the thread which throws it. In
other words, if you want a particular "catch" block to execute, you
need to move that into the code executed in the other thread.

Ouch... the whole basis of my approach is that one thread could watch
and use an exception to interrupt another thread that was not
performing well.
Could I name my main() thread and then have the watchdog thread throw
the exception on the main thread instead of its own thread?
What would the code for that even look like?
throw new Thread.Threads("main").ClearException(); //complete and
total WAG
- OR -
Should I be using some other mechanism to watchdog and break the hung
stream read?

No. The rule about catching an exception only from the thread in which it
was thrown is absolute. You can't inject an arbitrary exception into some
other thread.
However...

> stream read?
Since you didn't post much detail in your actual code, I can't say for
sure. But generally speaking, you can cause an exception on a thread
that's blocked on an i/o operation by closing the i/o object on which the
operation was started. Depending on the type of "ssh", you could probably
call "ssh.Close()" in your "watchdog" thread to cause an exception.
Note, however, that however you do this, you have a race condition in
which your watchdog thread could wind up closing the i/o object just
_after_ it successfully returned but before it was able to assign the
result to your "response" variable. This may or may not be an issue for
you.
Finally, note that you don't get to pick the exception that's thrown. So
your code would use the exception to detect the exceptional case (which is
as it should be anyway), and the lack of an exception would indicate
success.

the exception on the main thread instead of its own thread?
What would the code for that even look like?
throw new Thread.Threads("main").ClearException(); //complete and
total WAG
- OR -
Should I be using some other mechanism to watchdog and break the hung
stream read?

I have created a very simple C# class library (DLL).
I have ticked the "Register for COM interop" option in the project
properties dialog.
I have made the [assembly: ComVisible(true)] in the AssemblyInfo.cs file.
I can call a public method in this library from VBScript.
So far so good, now I'd like to have some very *simple* loggging capability.
For other applications I've gone down the [log4net] route and rolled by own
loggers etc...etc.
For this tiny DLL, I'd like to have for example the option to just drop a
[myDll.dll.config] file into the same directory as the DLL and add a trace
listener that outputs to a file or optionally roll my own trace listener
(i.e. udp).
I've successfully done things with trace listeners, but cannot get the DLL
to pick up the custom trace listener config file.
I've tried various names for the config file, but no joy.
Any suggestions?
Is it because I'm calling it from a VBScript file and not a .NET application?

Hi all
I have a MDI Container with a Form as MDI Child.
Now I want to set the Opacity on this child form
but it does not work ...
Does somebody know how to do this ??
Thanks for any comments

Maybe you can try with RegularExpressions
string local_pattern = @"[^0-9]";
System.Text.RegularExpressions.Regex local_RegEx = new
System.Text.RegularExpressions.Regex(local_pattern);
return local_RegEx.Replace(local_InputString, "");

If I understand your question correctly, the answer is "no". The "using"
directive applies only to the code file being compiled.
If you can explain more specifically how it is you'd think the
Designer-generated code file would use your other assembly reference, it's
possible that someone could come up with a different idea for solving
whatever problem you're trying to address. For example, how is it that
you'd expect the Designer-generated code file to even be aware of this
other assembly? What action in the Designer would you take that would
cause the Designer-generated code to use the other assembly?

As long as your application doesn't require the use of stored procedures,
you might want to consider shipping your app with SQL Server Compact 3.5
edition. It can be deployed by simply including the 7 required assemblies
and your database "SDF" file with your app; no special installation is
required. It also takes up *Way* less space.
