Hi All,
I have two forms in my app. I need to have functionality that when i click on nextButton on formA, formB should show and fromA should either hide it self or unload. Please help.
thanks,
Asif.

Set the forms' .Visible property.

Yup. Visible property would be good.
Try something like this:
this.Visible = false;<br />
FormB newForm = new FormB();<br />
newForm.ShowDialog();<br />
this.Visible = true;

That would imply the way you're trying to connect may not be right. Recheck the address and port number your app is using.

Are you using a proxy server to connect from your app? Your previous posts seem to indicate this. If so, set probably need to set your connection's .Proxy property.

I have a USB device I need to read from, the current software that runs the device has a lot of problems (needs administrator, crashed after 10 minutes, etc). The catch is that it is not a "human input device".
From what I have pulled from WMI, it uses the ClassGuid for a USB Hub ("{36fc9e60-c465-11cf-8056-444553540000}"). However, some USB snooping shows that the device has a bulk transfer end point, but only send information across the USB bus after the software is running.
Previous versions of the device were Serial/COM devices, so I am wondering if the "USB hub" has a hidden COM device on the other end.
Any advice on how to connect to the device would be greatly appreciated.

...How cool are they??!!
For ages I've wanted a regex facility on the String class, now I don't need to bother waiting for Microsoft never to add it as I can just write it myself in 4 lines of code!

Not that cool. Wait until you see how they get abused

Damnit! There I was being all optomistic and happy, and you had to come along and burst my bubble!

We'll see. I think extension methods are limited enough that there won't be abuse. I liken it to C#'s typedefing, e.g.
using Foo = blabhalbhabhalbahb;
..
Foo f = new Foo(); That feature was also open to abuse, as seen by all kinds of nasty C++ typedef'ing. C# limited its scope, and now we don't see abuse.
Likewise, I *think* extension methods won't be abused, or at least any abuse will be limited in scope, given that they have to be part of a static class and that consumers don't see them unless you specifically import that namespace. I think this limitation is a good one that will discourage abuse.

So for example you don't think this guy[^] is capable of abusing extension methods. I don't by it.

I don't buy it, either, because that's not what I'm saying. Most anything is abusable. Extension methods can be abused. But I think extension methods are limited in scope such that abuse is discouraged, and even when abuse occurs, it is limited (e.g. if I don't want to see your 420 extension methods on the string class, I don't have to).

Hmmm... now that concerns me, and I'll reread the spec, I don't want to be required to use the using directive just to use extension methods.
Can I please my wife by using extension methods?

Actually, I have to agree. I've just been playing round with a quick method to parse various types of data out as an appropriate type from a string, e.g.
string s = "1.12345";
double myVal = s.ToDouble();

I can't help but feel that I've seen this post somewhere else...

This is for a web app. I have a situation where I need to copy an bunch of files to another location but still give quick feedback to the user. Right now the file copy is inline and the performance is not great. I am considering threading off each file copy so I can give quick feedback to the user. If a copy fails it is not a big deal and the user will not access the copied files immediately. My concern is that hundreds of short running threads could drive CPU through the roof.... Does anybody have any experience with this or have any suggestions? Please let me know.

Hi Dave,
two comments:
1.
the normal approach to handle N jobs is to have a queue and a couple of threads; stuff all
the jobs in the queue, then let each of the threads fetch a job from the queue and execute
it, until the queue is empty. That way you get load balancing amongst the threads, and
only need a selectable but limited number of them, fitting the capabilities of the entire
system.
2.
whatever you do, chances are the limited bandwidth of your disk storage subsystem will keep
your CPU quite a long way away from the roof.

You should look into other aspects of the Microsoft Application Server family like Com+ or Message Queues for example. I advise against starting threads from an ASP.NET thread.

Hi,
i am trying to restart and application from within by using a batch file.
this is my batch:
TASKKILL /F /IM MyApp.exe /T
PAUSE
start MyApp.exe
when i run it by double clicking it - it does the job - closes and reopen MyApp.exe.
when i try to do it from the application by using :
System.Diagnostics.Process p = new System.Diagnostics.Process();
String path = Application.StartupPath + @"\";
p.StartInfo.FileName = path + @"ResetApp.bat";
p.Start();
the batch kill my application but doesn't restart it(doesn't get to the pause line in the batch file) - i guess that when my application is terminated it also kills the batch operation.
how can i detach the batch from the application, or is there other way to make my batch run from the application indepentlly?
thanks,
Samy

You could just try Process.Start(path + "ResetApp.bat");
Alternitavely, you could try starting your form, from within the OnFormClosed event, which gets fired:
[STAThread]
private static int Main(string[] args)
{
Application.Run(new MainForm());
}After the form has closed, but before your program actually ends.
^ This is of course assuming your using forms, and its not a console app.
