Hi,
you can launch all kinds of commands, including opening Word documents, or executing
DOS batch files, using the Process and StartInfo classes.
Put the batch file name into StartInfo.FileName, and optional arguments in StartInfo.Arguments.

Does anyone have any links to resources that may help me. I've been asked to come up with a proposal for an intercom type system, LAN based only.
The problem over normal VOIP is that the voice communication is a simulation of radio traffic, so the users on system may all be on different channels, only when connected to the same channel can they communicate.
To simplify, I'm willing to have a limited number of preset channels which users can join/leave. When two or more people are on the same channel, they can talk to each other in a half-duplex method.
I was thinking about having a "server" machine and using some form of remoting allowing users to call a common Talk() method on a remote instance (thus allowing the blocking others from talking if required).
My questions really are related to the "streaming" of the transmit from the "talker" out to the "listener".
I should have time to do a good implementation, but need to present the posposal at the start of next week!
Any links, ideas would be welcome.
Regards,
Ray

I'd love it if there were... and money isn't that big an object for the right product (it's an important component of an 8 figure project).
The latest spanner added to the design is that listeners need to be able to listen to multiple independant channels at the same time! I'm convinved we'll end up creating the framework but I'd still love an API/library to do the comms/audio side of things!
In the mean time, I'm presenting the solution without going into programming/implementation specifics -- since that is actually inappropriate at this early stage of my project!

hi
Is there any way that we could shut down and restart our system through our c# applicaiotn ? thanks in advance
hello

|
|
|

To know more about other command write shoutdown /? at command prompt.

Thanks
but this code goes into abnormal execution ,, forms statrs opening countless
so amazing ,, why is that? i am using dont net v 2
thanks in advance
hello

It can probably be done through API calls. I know their are methods that allow you to show the ShutDownDialog. Try looking for API Guide and API Viewer on Google, and look through their listing of API commands.

Hi all
I have a c# application which sends a singnal through com port on some device attatched on the local system com port , every thing goes ok when i run this application from the local system (workgroup)and i can send and receive singal from local system's com port,, but the problem is that when i run this application on a system which is client of a central server(win2003 server) , it doesnot detect device on its local com port it searches device on the com port of server computer and because there is no device on the com port of remote server so my application does not work , thoug it is network isuue ,, but any idea > what to do ?
thanks in advance
hello

What do you mean by "on a system which is client of a central server"? Are you saying that this local machine is running a Terminal Server instance on the Win2K3 box? If so, this arrangement won't work since your actually running the application on the server, not the local workstation.

yes its an instance ,, but there is also a RFID card(ps2)attatched ,, but this machine detects this and respond,, so why it cant detece its local com port ?
i thing i am wrong not cleared with the concept somewhere plz help me
thanks in advance
hello

Terminal Services run an instance of a workstation on the SERVER, not the local workstation. The local workstation just shows you the display of the remote Windows session. The TS Session will NOT interact with the local machines hardware devices. It's just like your keyboard and mouse are connected to the server itself.

Hi, here is my scenario...
i have the following in my solution...
App1 - normal application
App2 - normal application
CoreApp - library containing classes and 'core' functionality
App1 and App2 talk to each other via their sql server databases.
now, sometimes app1 and app2 may be installed on the same server, sometimes they are not.
so, if they are installed on the same box there will be a connection string to the other apps db in their web.config file.
if the connection string does not exist then i must call the other apps web service which will perform the db insert for me.
i made an interface, lets says its called IComms
it defines the method signature that allows app1 to put something in app2s database.
so to send a message i write this code in App2..
<br />
<br />
dim proxy as IComms<br />
'see if we have connection string for app1 database<br />
<br />
if getConfigSetting("App1ConnectionString").length = 0 then<br />
'use web service<br />
proxy = new app1.webservice<br />
else<br />
proxy = new CoreApp.dbCalls<br />
end if<br />
<br />
proxy.sendmessageToApp1("hello")
this is all very well, but the reference to app1s web service in app2 does not create an implementation of the interface on the proxy class.
is there any way round this or should i just design the app without the use of an interface?

hi,
when sending mails using SmtpClient, does it open connection each time I do .Send()
if yes how can i avoid it?
If no what is the mechanism used to send Email.
cheers
------------------------------
Its not the fall that kills you; it's the
sudden stop at the end.

|
|
|

Yes it does and no, you can't avoid it. Each time Send is called, it opens a connection, sends the email, then closes the connection. You can't get it to keep a connection open. THe only way to do what you want is to write your own implementation of an SMTP Client that specifically includes the functionality you're looking for.

Hey everybody.
I would like to know speed differences between vb6 and C#. How much C# is slower because of the CLR? Do you know some good web site where this is tested?
Thanks in advance,
Fedor

I don't think anyone has tested VB6 against C#. Test it yourself if you have any doubts. But, I think you'll find that the .NET CLR doesn't make C# or VB.NET slower than VB6. I think you'll find just the opposite.

I assume that you mean how much slower managed code is compared to unmanaged, as the CLR (common language runtime) is not very different from how VB6 works. VB6 also has a runtime library, the difference is just that it's specific for VB6 and not shared with any other language.
Here[^] you can find a comparison between C#, VB6 and other languages.
As you see, C# is roughly twice as fast as VB6 for simple operations. When using objects the difference grows substantially, as C# is roughly 100 times faster than VB6.
The difference in performance when it comes to objects is largely due to the way that the managed code handles objects, so you see that managed code doesn't make C# slower, but in fact very much faster.

Expose the c# application (or at least the interfaces you are interseted in) as a COM object, use tlbexp to export a type library for early binding...

|
|

Thanks,
But can you eaplain or give some like to example how to do it ?
Im new in the .NET framework issue ....
