Hi Everyone.

I am very limited on my vb.net skills, i am using vb.net in .net 4 Framework. I was wondering if someone could assist. i have searched google finding mimial result, im not sure if i am using the correct terminalogy for what i want to achieve...
but basicallyI have a form with a 4 textboxs(txtinfo, txtip, txthost, txttime) When the form loads it loads a textfile to TXTINFO. (please see below)

IP Address: 10.21.4.1, Host: RTR-BIF01,Time: 18:00 GMT

My issue is from this string i want to be able to pull out the nessary info to display in the other textboxs, soo i want to remove the Header names - IP, Host, time...example

VB

txtip.text = "10.21.4.1"
txthost.text = "RTR-BIF01"
txttime.text = today.toshorttime.tostring

Any information would be great or help would be great...once again my skill set for vb is very limited..

Thanks in advance

Solution 1

This is fairly simple to achieve. Split the string at the comma, then remove the IP Address: Host: and Time: portions of the text, saving what's left into your text boxes.

One option to remove them is like this:

VB

replace(VARIABLENAME, "IP Address: ", "")

Edit: Here is an example

VB

Dim infoString As String = "IP Address: 10.21.4.1, Host: RTR-BIF01,Time: 18:00 GMT"
Dim split As String() = infoString.Split(","c)
txtip.Text = Replace(split(0).Trim(), "IP Address: ", "")
txthost.Text = Replace(split(1).Trim(), "Host: ", "")
txttime.Text = Replace(split(2).Trim(), "Time: ", "")

No, it's alright... I usually give enough information to let the other person have a crack at it themselves rather than a full solution...

Check this Link http://msdn.microsoft.com/en-us/library/b873y76a.aspx

Edit: I update my example to show the use of Trim() (to remove any unwanted whitespace)

Solution 2

Use Split method for this

C#

string ss = "IP Address: 10.21.4.1, Host: RTR-BIF01,Time: 18:00 GMT";
           string[] split = ss.Split(new Char[] { ',' });

           ArrayList al = new ArrayList();

           foreach (string s in split)
           {

               if (s.Trim() != "")
                   al.Add(s);
           }

and assign value to text boxes as

C#

al[0].ToString().Replace("IP Address: ", "").ToString();
al[1].ToString().Replace("Host:", "").ToString();
al[2].ToString().Replace("Time:", "").ToString();

Hope now it works

However for this particular string this code
ArrayList al = new ArrayList();
foreach (string s in split)
{
if (s.Trim() != "")
al.Add(s);
}
is not necessary. Just do this i.e.
txtip.Text = Replace(split(0).Trim(), "IP Address: ", ""))
