[RESOLVED] Help With File Transfer Again Please..

Ok well i got most of it sorted out but i got a new problem an i can't seem to fix it if anyone has time can you optimize my code? the problem i'm having is when i send a file from computer A to computer B , Computer B trys to saves as computer A's directory EG computer A say C:\documents\usernamex\desktop while computer B c:\documents\diffusernamek\desktop so when i send a file to b from a it trys saving as a's directory but it doesnt exist becuase its on a an vice versa?

Code:

---

Private Sub senddataa(sFile As String, sSaveAs As String, tcpCtl As Winsock)
On Error GoTo ErrHandler
    Dim sSend As String, sBuf As String
    Dim ifreefile As Integer
    Dim lRead As Long, lLen As Long, lThisRead As Long, lLastRead As Long
   
    ifreefile = FreeFile
   
    ' Open file for binary access:
    Open sFile For Binary As #ifreefile
    lLen = LOF(ifreefile)
   
    ' Loop through the file, loading it up in chunks of 64k:
    Do While lRead < lLen
        lThisRead = 65536
        If lThisRead + lRead > lLen Then
            lThisRead = lLen - lRead
        End If
        If Not lThisRead = lLastRead Then
            sBuf = Space$(lThisRead)
        End If
        Get #ifreefile, , sBuf
        lRead = lRead + lThisRead
        sSend = sSend & sBuf
    Loop
    lTotal = lLen
    Close ifreefile
    bSendingFile = True
    '// Send the file notification
    tcpCtl.senddata "FILE" & sSaveAs
    DoEvents
    '// Send the file
    tcpCtl.senddata sSend
    DoEvents
    '// Finished
    tcpCtl.senddata "FILEEND"
    bSendingFile = False
    Exit Sub
ErrHandler:
    MsgBox "Err " & Err & " : " & Error
End Sub

Code:

Private Sub Winsock2_DataArrival(ByVal bytesTotal As Long)
    Dim strData As String
    Dim ifreefile

    Winsock2.getdata strData
    If Right$(strData, 7) = "FILEEND" Then
        bFileArriving = False
        sArriving = sArriving & Left$(strData, Len(strData) - 7)
        ifreefile = FreeFile
            Open sFile For Binary As #ifreefile
            Put #ifreefile, 1, sArriving

        sArriving = sArriving & strData
    End If

End Sub

Code:

---

Private Sub Command4_Click()
    If Dir$(txtFile) = "" Then
        MsgBox "File Does Not Exist"
    Else
        senddataa txtFile, GetFileName(txtFile), Winsock1
    End If
End Sub

Private Sub Command5_Click()
    If Dir$(txtFile) = "" Then
        MsgBox "File Does Not Exist"
    Else
        senddataa txtFile, GetFileName(txtFile), Winsock2
    End If
End Sub

---

Code:

---

Public Function GetFileName(flname As String) As String
Dim posn As Integer, i As Integer
Dim fName As String
   
posn = 0
For i = 1 To Len(flname)
If (Mid(flname, i, 1) = "\") Then posn = i
Next i
fName = Right(flname, Len(flname) - posn)
GetFileName = fName
End Function

I make command 4 visible when its the listener or host an command5 hidden vice versa if they connected other way can anyone help :confused:

You will have to create the remote folder if it does not exist:
Dim lDestFolder As String
Dim diffusername As String

diffusername = "YourRemoteUserName"
lDestFolder = "c:\documents and settings\" & diffusername & "\desktop\MyFolder"

If Dir$(lDestFolder, vbDirectory) = "" Then
MkDir lDestFolder
End If
Exit Sub
Be sure diffusername is correct

That's the thing though i just want the file to save where the program application is it does do that but it somehow sends one computers directory to the other to save the file which the directory is non existent because it sends its own computers directory to save on other computer but ugh idk im confused

So your saying it does not send just the file, it also sends the path to the file on the sending machine ?

Yea like it sends but it doesnt send all of the file now, and like say this app is located on your desktop eg c:\documents and settings\johndoe\desktop and the other computer is c:\documents and settings\janedoe\desktop so if you send a file to janedoe from johndoe janedoe trys to save it as johndoe's path and vice versa if you want to take a look ill attach its no big secret xP

if you have time to look an help id be so grateful :) :) :)

Ity looks to me you are just sending a string with no reference to a file:

Code:

---

Private Sub Command2_Click()
Dim sName As String
Dim sData As String

If sckconnect.State = sckConnected Or scklisten.State = sckConnected Then
sName = ReadRegKey(HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon", "DefaultUserName")
sData = sName & "..::.." & Text2.Text

Text1.Text = Text1.Text & sName & "..::.." & Text2.Text & vbNewLine

sckconnect.senddata sData

Lul forgot to mention im using multiple winsock controls, that peice of code is just for the chat, Winsock1 And Winsock2 is the file transfers and senddata/getdata are used for the screenshot video preview

You might need help from someone who knows about Winsock. Seems something is missing to me. It looks like the destination path has the where and text combined (sData). Never tried what you are doing. I will be interested to see how this comes out. To be sure i am understanding you want to write text messages on a remote desktop with no file involved?
Someone here will probably have a solutation.

Okay well im basically makeing a remote desktop helper i got the idea cuz my dad keeps getting viruses and this way he'll be able to direct connect with me if he needs help as well as if others want it too the breakdown

1. Chat-You will be able to chat while connected back and forth
2. File Transfer-Send files back and forth
3. Preview of there desktop (host only)

all of these i am using in this program as one single desktop helper so they all connect at the same time thats why i have multiple winsock controls everything works except the file transfer giving me a headache, so basically everything connects at same time so you can chat,transfer files and preview there desktop , just having trouble with the file transfer xP but if anyone else would like to help you welcome too it thanks though for peeking at it :)

I was checking into something similar a while back to make a live help for my website., but could not get past the ports and Ip parts, I finally settled on a free one http://www.livezilla.net/downloads/ and gotta say it sure works good for free.
Of course who knows free for how long. It has all the things you specified except the ability to view a remote desktop. I hope someone helps you as I may need the answer down the road myself. This site has some very sharp coders. If nobody helps in the next day I will post the same question if you don't mind

I think ive found the problem im gonna do more testing an keep you updated

I'm glad Thank you

Hey yo, alright i seemed to have to fixed it pretty damn good if i say so myself, bunch errors on top errors but got em all heres a list for future references

1. Like before never put DoEvents in a data arrival event i've learned that now
2. I was not specifing a save path for the file when it arrives easily done with a directory box or commondialog control, preferably directory box for me
3. It wasn't sending the filename and extension properly easily fixed on the data arrival event
4. On data arrival event for files you must clear the old binary data out of the temp string on send file complete else it would merge with other data thus cause corrupt data

Lol took me awhile to think the code over but it is working properly , if you would like the source+project let me know this could be as helpful to you as it is me, as i said before it is a remote desktop helper designed for mainly56k and really high connections :wave:

Thanks I would like to have the source code, as I will probably be making my own live chat at some point.
I have had run in's with DoEvents a few times. It has caused me a great deal of problems and other times it was a perfect fix. Just yesterday I was trying to make a form invisible and it fixed my problem:
Me.Visible = False
'DoEvents
Sleep 1800
Me.Visible = True
The form would only be partially invisible until I added doevents
