question on this function i found

VB Code:

Public Sub SendFile(SocketObject As Variant, ByVal FilePath As String, ByVal PacketSize As Long)
    Dim lonFF As Long, bytData() As Byte
    Dim lonCurByte As Long, lonSize As Long
    Dim lonPrevSize As Long
    
    On Error GoTo ErrorHandler
    
    lonSize = FileLen(FilePath)
    
    Open FilePath For Binary Access Read As #lonFF
        
        ReDim bytData(1 To PacketSize) As Byte
        
        Do Until (lonSize - lonCurByte) < PacketSize
            Get #lonFF, lonCurByte + 1, bytData()
            lonCurByte = lonCurByte + PacketSize
            SocketObject.SendData bytData()
            DoEvents
        Loop
        
        lonPrevSize = lonSize - lonCurByte
        
        If lonPrevSize > 0 Then
            ReDim bytData(1 To lonPrevSize) As Byte
            Get #lonFF, lonCurByte + 1, bytData()
            lonCurByte = lonCurByte + lonPrevSize
            SocketObject.SendData bytData()
        End If
    
    Close #lonFF
    Exit Sub
    
ErrorHandler:
        Debug.Print "Send File Error"
        Debug.Print "---------------"
        Debug.Print "Number:      " & Err.Number
        Debug.Print "Description: " & Err.Description
        Debug.Print "File:        " & FilePath
    
End Sub

so does this function only send the contents of the file?? not the actual file itself?

how can i end up viewing the file then if its a .png .html etc?
i want to be able to transfer files (rather than just file contents)between myself and another user thorugh a winsock connection

You send files in chunks, usaully 4096 or so bytes at a time(multiples of 1028 bytes). Winsock can't really deal with sending large amounts ot data at once. Would probably be ok sending a whole file over say a home LAN, but over the net your most likely going to end up with a corrupt file at the other end. So the client takes a chunk of the file (GET #1,,strChunk) and sends it to the server. The server then starts to reconstruct the file, chunk by chunk, using the PUT command (PUT #1,strChunk)... etc. The client sends the next chunk, server add this to the previous etc.. until all the file is sent. The do Loop ensures this.

So you are sending the actual file and not the contents, your opening it as Binary.

so this wont work for .png or other files? only.txt files?

when the client sends the file to the server, do i have to put some code on the server winsock too?

i want it to store the sent file in documents
