Help with structures and files

Hi, I'm new to VB, this is the first time I use it, so please excuse my ignorance.

This is what I want to do:

<filecontent>
data1moredata1andsomethingelse
</filecontent>

I need to open a file in binary mode, then read the first 4 bytes into a variable, the next 9 into another and the 16 left into a 3rd one. I know this is done via structure, declaring 3 variables and the specific length of each other, but, how?

Can anyone give me an example on how to work around this?

Thx in advance.

Well, as noone replied I'm gonna reply myself with the solution :ehh:

<filecontent>
1234onestringanotherstring
</filecontenet>

Code:

---

Private Structure Struct1
        Dim iID As Integer
        <VBFixedString(9)> Dim sOne As String
        <VBFixedString(13)> Dim sTwo As String
End Structure

Public Function Action(ByVal sFilePath As String)
        Dim Struct1 As New Struct1
 
        FileOpen(1, sFilePath, OpenMode.Binary, OpenAccess.Read, OpenShare.LockRead)
        FileGet(1, Struct1)

      'more code
      'Struct1.iID is 1234
      'Struct2.sOne is onestring
      'etc

End
