show these portions of your code
1. how you create your serial port reader
2. where you get the text from the serial port and attempt to assign to the textbox's Text property.

Serial Port Declaration :
private SerialPort comport = new SerialPort();

reponse from com port : string response = comport.ReadExisting()

Changing the value : textbox1.text = response.Substring(0, 1)

There's nothing using threading in the code you've posted. I assume you're using a thread to read the port, is your serial port declaration in there?

BTW, there's a simple example on MSDN[^] - it might be worth comparing to your code.

I guess you're setting the text from within the comport_DataReceived event handler, which the SerialProt object calls from another thread. Either you read up on threading, or you don't use the event but put a timer onto your form (or control) and poll the com port from the timer's Tick event.

Hi all,

I have the following method: GetNodeByName, so the thing is that I can get hold of the specific treenode but how can I select it?? Confused | :confused:

public TreeNode GetNodeByName(TreeView treeView, string key)
{
    TreeNode[] nodes = treeView.Nodes.Find(key, true);
    return nodes.Length > 0 ? nodes[0] : null;
}

Can anyone please put some light on this issue
Many thanks in advance

Is this what you mean?

System.Net.Dns.GetHostByName( "www..." );

edit: apparently GetHostByName is obsolete - use GetHostEntry now Blush | :O

Thanks! I needed something as simple but I still cant see the ip address!!

I tried

public static string GetWebsiteIP(string websiteName)
{
    IPHostEntry host;
    string strIP = String.Empty;
    host = Dns.GetHostEntry(websiteName);
    foreach (IPAddress ip in host.AddressList)
        strIP += ip.ToString();

    return strIP;
}

But I still get the website name I pass Confused | :confused:

GetWebsiteIP("www.codeproject.com"); //the output is still "www.codeproject.com"

Just tried it and it works for me Confused | :confused:

Also, a domain name can map to multiple IP addresses, so you might want to return a string[], or maybe just pick the first one?

Hi mister,

I have an Winforms app (Client) and Web app + WCF Services + Windows Services (Server). In server, I have installed SQL SERVER 2000.

Now, I want create a installer (MSI.exe or another Winforms app) to create a database, perhaps user, tables, stored procedures, .. Only the user introduces name of database, server, and if has Windows authentication; if not Windows authentication, I need user and password.

I have several scripts SQL, that I need execute too. If I use isql command I have problmes with codification because my scripts sql have Spanish characters. I tested with using ANSI and UTF-8 encoding for scripts .sql files, but didn't work.

Finally, how I can create this installer ? is it better MSI ?? or can I create an WinForms app ??

Any sample will be very very grateful.

Thanks in advance.

hi
how can i call a static method declared in Form1 from business_logic layer

i can call business_logic layer methods from Form1 because :

-------------------form1------------------

using business_logic
------------------------------------

but cannot see form1 methods from business_logic layer because :

----------------- business_logic layer ------------------------

using form1 //does not allowed because of circular dependency
-----------------------------------------------

so what can i do ?

Take the slightly longer way around, inside business_logic use myNamespace.form1.myMethod
