You can use Process.Start() to start a new process, and you can use Environment.CommandLine to get the command line the program was started with.

hi..

I created a windows application, I have 1 Picturebox & 1 button, when I click the button Picturebox should rotate (means flip), and the user should get 2D effect of the Picturebox (like in power point presentation the animation that we use to switch between the slides).
Any solution’s or links related to my question are kindly acceptable...

hi
you can register com objects with regsvr32.exe. pass the full filename as parameter.
after registering, add a reference to your project selecting the com object registered before.

visual studio create a wrapper for the com object and add this wrapper as refernece to the project.

regards

in this case your exe ist not a com object. all com object must contain
DLLRegisterServer and DLLUnregisterServer methods. this methods register/unregister
the com object.

Just so you know, you shouldn't post your question in lots of forums at the same time. Just pick the one most relevant forum and post there only.

In this case, the C# would have been the best place.

Check out the InterOp toolkit, part of the VB.NET powerpacks. You can easily port this to C#, various examples can be found both here and on Google.

Good luck Smile | :)

How do you talk to a remote serial port over a network?

alb1081117-Nov-08 22:04

Hi all

I have a project in which I have to communicate with a serial port on a piece of hardware. The hardware connects to a router via a standard Ethernet cable and is assigned an IP address and the serial port has a port number of 49510.

What I am hoping to do is send a string such as "ZOOM;1;0;FF,30,30,00,A2,32,EF;;;" from a remote computer on the network, to the serial port and then to listen for a response. I think this needs to be in TCP/IP format however I'm just new to C# socket programming and not sure how to achieve the end result.

Any help would be greatly appreciated.

comparing ascii values

I am using following code to verify whter enterd char is an alphabet.

theAddress.Substring(i,1).ToLower < "a"

The code runs perfectly in vb.net if I use Lcase but fails in c#.net.
The error is:

Error 1 Operator '<' cannot be applied to operands of type 'method group' and 'string'

How else can I do that.The code is in a for loop.

Plz help.I'd be obliged.

Well the error you are getting is because you missed the () from after the ToLower. It's a method call so you need the brackets. C# isn't like VB, you can't miss out the brackets if you don't pass any parameters.

But your next problem is you can't use '<' to compare two strings. '<' only works on Char data types, not Strings. You could call .ToCharArray() on your string to get it as a character array and pick out the character from the array you want to look at, and then if you use single quotes (') rather than double quotes (") for the 'a' then that will be treated as a character too. But that would be a rather painful way of doing it.

There are built in functions to do this kind of thing. Just do this:

Char.IsLetter(yourString, i);

Hi Simon,
I don't have VS in front of me but I think String has a Compare method. String.Compare, right? If so, He can use this method to compare his string instead of converting that into char array.

HisString.Substring(i, 1).ToLower().Compare("a");

I'm not sure if there's any Compare method in String. If there isn't, My apologize Smile | :)

[Edit]
Oh yes, I found that.

HisString.Substring(i, 1).ToLower().Compare("a");
String.Compare(HisString.Substring(i, 1).ToLower(), "a");

Look here[^]

Of course you can. As the string contains a single character, it will even work as expected, but it's not optimal.

Despite everything, the person most likely to be fooling you next is yourself.

It doesn't work for me. Try this:

class Program
{
    static void Main(string[] args)
    {
        String s1 = "test1";
        String s2 = "test2";
        if (s1 < s2)
        {
        }
    }
}

I get:

Error: Operator '<' cannot be applied to operands of type 'string' and 'string'
