Parsing file.

Hi Gurus,
I am struck here with this issue and need some help:
Input file need to split into two output files as shown below.
The filelayout shown has header and details records I have to identfy the detail records say(105 - shown in below example) and need to be written in to another file with the header info.

Thanks in advance for your help.

Thanks

Each line consists of the following parts:

Some ID (4 characters), some CODE (3 digits) and NAME.

You need to open a file and read the lines.
Then you need to use .Split method of the System.String class to split each line into 3 tokens.
Then you can create a collection with these fields. For better handling of the information I suggest to use this class:

Code:

---

Class Record
    Public ID As String
    Public Code As Integer
    Public Name As String
End Class

---

Alternatively, you can use a Datatable.

The second step would be sorting your table or collection out and filtering (by name or by code)

Finally you open the output file and write the information back.

Now, which particular part of the above you don't know how to accomplish?

Thanks for the advice,
here the catch is there might be multiple employee sub-groups - with in dept group, knowing that perticular sub-group need to be seperated,
what would be the best process to follow.
can we write these sub-groups in seperate file and append to the actual file.
please help.
