Sending/receiving Data
How can you receive files or send files to diferent machines? Is there some command in winsock that helps you achieve this? Do you know some code for this? or even a web-site that explains this? If you do know some info then do tell me...

thankyou very much


Sending And Receiving Data For A Game
I'm working on a simple round to round based game (kind of like turn based but not quite). I'm just learning the winsock control and I've learned a good portion, such as setting up the tcp/ip connection and sending and receiving data. So now comes my next problem. Here's the game code will work:

The game has the code for both host and client. During the starting of the game, the host has randomize variables for the 30 planets, and then send all that information to the client. So it looks like this: (planets is a user defined variable type i have to contain each planet data in an array. stargrid is an image array, 0 to 109, on form1.)

For a = 0 To 29

If host = True Or p2player = True Then

b = Int(Rnd * 109)
Loop Until planets(b).exists = False

Dim conArmy As Integer
Dim conRegen As Integer
conArmy = Int(Rnd * 45) + 15
conRegen = Int(Rnd * 20) + 7

End If

planets(b).exists = True
planets(b).grid = b
stargrid(b).Visible = True
stargrid(b).Picture = neutralplanet.Picture
planets(b).regen = conRegen
planets(b).army = conArmy
planets(b).temparmy = planets(b).army
planets(b).owner = "Neutral"

Next a

The IF section is the part that the host has to randomize for each planet. After that, it just sets the variables with the info. What i need to do is send those variables to the client. But when i send the data and receive the data on the client side, it sends so fast that the buffer contains the last variable and the client sets all the variables to the last variable isntead of getting the data seperately each time. (i hope that made sense). What i have set is an IF statement. If host = true, then it sends all the data seperately using functions i wrote. If client = true, then its set to receive the data using another function. And here they are.

Public Sub Winsock_DataArrival(ByVal bytesTotal As Long)
Winsock.GetData incdata
receiving = True
End Sub

Private Sub Winsock_SendComplete()
sendcomplete = True
End Sub

Public Sub Gsenddata1 (data1)
sendcomplete = False
Winsock.SendData data1
Loop Until sendcomplete = True
Unload Waiting
End Sub

Public Sub Ggetdata1()
Loop Until receiving = True
End Sub

I know my explanation might be alittle confusing.. I'm hoping someone can help me figure out a way to seperate the sends and receives? My only idea so far is to create another array that contains the incdata variable, and will have to make that work somehow, lol.

[VB6] Sending And Receiving Data With Winsock
I want to make a simple program that will be able to send and receive text messages and files by communicating with same program that is running on different PC. It will use TCP/IP connection.

Is it possible to make it with Winsock, and if it is, could someone explain to me or give me a link to a good tutorial for this.

Edit: And one more thing.- I have red that for small amounts of data, UDP protocol is used. So if i only want to send messages, is it better to use UDP protocol instead of TCP?

Receiving And Sending Complicated Data
I'll explain this as much as I can...
I need to grab data from an Xbox and send it to a remote computer, which will inject the data into another Xbox
I will be using PacketX( for this
This is one of the packets (or data from the Xbox)
In Hex:


for faster transfer of this packet to the remote computer, I change it into ASCII with a function hex2ascii(...) making the length of the packet half as much

This is what I need to do....
Now, when recieving the packet, I need to change it back to hex and put each of them into an array

Array(&hFF, &hFF, &hFF, &hFF, &hFF, &hFF, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, _
&h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, _
&h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00, &h00)

then send them to the Xbox by using that array

I've tried various ways, but none of them have worked

Sending/receiving Data With Multiple Connections
Hello, this is not really a Winsock question, but I need to send/receive data with multiple connections and I'm not really sure how to do this. It's a bit complicated, but I'll try to explain it the best I can.

I have several items in a Listview. To each Listview item belongs a Collection with strings (between 1 and 300). I need to send each string in the first Collection to the server and the server automatically sends data back. This needs to be done with multiple connections.

After all the strings from the first collection have been sent to the server and all the data the server has sent back is received, then the item in the Listview has to be removed.

Then all the strings from the second collection have to be send to the server. After all the strings from the second collection have been sent to the server and all the data the server has sent back is received, then that item in the Listview has to be removed... etc, etc, until the end of the Listview.

Below is some pseudo code. I'm specifically having problems with the "DownloadNextPart" sub.

Option Explicit

Private col(1 To 5) As Collection
Private strData(1 To 4) As String
Private BufferData(1 To 4) As String

Private Sub Form_Load()
Dim i As Integer, x As Integer

For i = 1 To 5
lvwItems.ListItems.Add , , "Item in Listview: " & i 'several items in the listview

'add strings to the Collections (just an example)
Set col(i) = New Collection
For x = 1 To 50
col(i).Add "string to send to the server"
Next x

Next i

End Sub

Private Sub Command1_Click()
Dim i As Integer

For i = 1 To 4 '4 connections to the server
Sockets(i).Connect "", 80
Next i

End Sub

Private Sub Sockets_Connect(Index As Integer)

Call DownloadNextPart(Index) 'start downloading when connected to the server

End Sub

'I'm not sure how to make this work properly
Private Sub DownloadNextPart(Index As Integer)
Dim i As Long

With lvwItems
For i = 1 To .ListItems.Count 'loop through listview items

If Sockets(Index).State = sckConnected Then

'send next string in collection
'if there are no more strings to be sent from a collection then
'start sending strings from the next collection ????
Sockets(Index).SendData col(.ListItems(i).Tag).Item(???????) & vbCrLf

Exit Sub
End If

Next i
End With

End Sub

Private Sub Sockets_DataArrival(Index As Integer, ByVal bytesTotal As Long)

Sockets(Index).GetData strData(Index), vbString 'get data

BufferData(Index) = BufferData(Index) & strData(Index) 'buffer data

If InStr(1, BufferData(Index), "...") Then ' all data has been received
'do something with it

BufferData(Index) = vbNullString 'clear buffer
End If

'if this is the returned data from the last string
'in the collection, then remove Listview item ?????

Call DownloadNextPart(Index) 'download next part
End Sub

Mscomm Control - Sending /receiving Data To/from Serial Port (com1)

Sending And Receiving E-mail
I need to know how to send an e-mail from my VB6 program, and how to receive an e-mail, and place its contents into a variable. I've searched this thread and have had no luck implimenting any of the routines described here.

CDO The simplest seemed like using CDO, but I have Win XP my references list only contains CDO for Windows 2000, and if I try it anyway, VB crashes and closes.

SMPT. I followed these instructions:

for use with Visual Basic 6 (any edition):
1. download
2. unzip OSSMTP.dll from it to Windows System directory
3. run "regsvr32 OSSMTP.dll" from command-line

I don't know what "from command-line" means (dos perhaps?), but I press the Windows button + R to get the Run Dialog box. Then I typed "regsvr32 OSSMPT.dll and pressed OK. It told me the installation was a success.

I downloaded a zip that had a sample .vbp from
I put my own e-mail address after the = in the ".MailTo =" line. The first time I ran it, it locked up VB and I had to control+alt+delete to exit. The next time I tried it, it didn't crash, but there was no e-mail in my mailbox.

Any help would be appreciated.

**** edit ****
I kinda got it to work, but I had to make up a hotmail account. If I send mail to my new hotmail account, the program seems to work OK, except the e-mail doesn't show up in my mailbox. If I send to my other e-mail address, it tells me invalid address for an address that I know to be valid.

It gives me this:


220 Microsoft ESMTP MAIL Service, Version: 5.0.2195.6824 ready at Thu, 8 Jul 2004 18:12:56 -0700
250 Hello []
250 OK
354 Please start mail input.
SUBJECT:Test mail from control

250 Mail queued for delivery.
221 Closing connection. Good bye.

Everything here looks good, but I get no e-mails sent to my hotmail account.

When I change to the mail server for my other e-mail address, I get this:


501 5.5.4 Syntax error in parameters or arguments

Sending And Receiving Speech
Hello, I thought I remembered someone asking this question awhile back but couldn't find it. Anyways, I was wondering if someone could point me to somewhere where I can learn to make it so that people can send and receive the sounds that people are saying. For example

My Computer: Through my microphone I say "Hello"
Some other computer: Receives the "Hello" through his speakers. and says "Hello" back
My Computer: I receive what he says.

Any help would be great!

Sms Sending And Receiving Using Mscomm.. Help..
hi! gud day..

currently, im developing a sms application using VB6 (mscomm) and AT commands, w/ my 6210 and datacable(DLR-3P)..

i have already tested (AT commands) and tried sending/ receiving sms using hyperterminal, and it works..then wrote i have found a code (below; similar to the AT commands i have tested in hyperterminal) from the net, and pasted to my form;
changed a few (TEXT BOXES, for the mesg and the recipients number); however why it seems, it dosen't work, when i run (F5) the program; but when i try to debug it (F8) it do works, and i was able to send sure that i didnt worked since, i checked my phone credit (load) everytym i test the program, and nothing was subracted.. is there a problem with the code?

second, is there a way i can see in VB the values "error", "ok", "+cmgs:321"; the reponses of the modem after an command is executed, like when i test it to hyperterminal.. i would like to do some error trapping with that, and eventually put a alerts like "message failed" or "message sent".. bcoz when i run this code, i have to look at my phone, and all it says is "terminal connection interrupted", i couldnt tell if the mesg was sent or an error has occured..

third, im also programming the receive module of this program.. what i did was to modify some of the codes of sending sms..
(also see below).. i have tested the AT commands, and it works with hypertermnial.. but, my 3rd problem is, i dont know what to do next.. i have reading some threads of placing an code in commEventRecv.. i hav tried dat, but still it dosent seem to work..

can anyone help me with these.. pls.. i really need it for my project w/c is due less than 2 weeks.. please..

im really sorry, im new with mobile programming... and i had to jump start to AT commands, since it is a prequisite of my project (that the program that i will develope should be scalable to gsm modems; kinda plug and play concept)..

thank u to all.. i appreciate ur time of reading this on, andd all the suggetions, the help u culd give..

thanks u very much..

happy holidays!!

Thanks a bunch

Sending And Receiving Email With VB/VBA
I want to write a simple application that runs on my PC at home. I want it to do two things.

1) Periodically check a given email account on a POP3 server, write the email information (from, time, subj, text) to a text file, and delete the message from the server.

2) Periodically check a given directory on my hard drive, take the files that it finds there and send them via email to the address specified in the file.

The file handling and parsing I know how to do, integrating the email is trickier because I really don't know much about it. The system has Outlook Express installed and that is the mail client I want to continue using.

Any help would be appreciated.


Receiving (and Sending) Faxes In VB - Is It Possible????

Receiving/Sending E-Mail Through VB6?
Hello everyone,

I'm creating a basic remote-control application.  The server runs on my machine, then I can send some commands from my mobile phone (via email, hopefully) to my server machine to perform various functions.

Is it possible to send and receive email using VB6?  I'm broke, so I can't pay for any professional solutions.

Thanks for your help,


Server Sending && Receiving
I am new to writing client-server programs and i am having a problem getting my server program to send as well as receive on one port. I know it is something simple.  I even took out all the added stuff my program does to boil it down to the basics to test it.  But it still didnt work.  
Here is my test code:

Server side:

Private Sub Set_to_Listen_Click()
Winsock1.LocalPort = 8866
End Sub

Private Sub Send_to_Client_Click()
Dim buffer(0 To 2) As Byte
buffer(0) = 1
buffer(1) = 1
buffer(2) = 1

Winsock1.SendData buffer
End Sub

Private Sub Winsock1_ConnectionRequest(ByVal requestID As Long)
If Winsock1.State <> sckClosed Then
End If
Winsock1.Accept requestID
MsgBox "connected"
End Sub

Client Side:

Private Sub Listen_for_Server_Click()
Winsock1.LocalPort = 8866
End Sub

Private Sub Establish_Connection_Click()
If Winsock1.State <> sckClosed Then
End If
Winsock1.RemoteHost = ""
Winsock1.RemotePort = 8866
End Sub

Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
Dim sData(0 To 2) As Byte
MsgBox "freceived"
Winsock1.GetData sData, vbArray + vbByte '1

End Sub

The server hits the "set_to_listen" button, then the client hits the "establish_connection" button.  Once that is done the client hits the "listen_for_server" button and the server sends the data over.  At this point i get "Wrong protocol or connection state for the requested transaction or request" error.

I am using 2 computers and if i can get this test working i think i can get my larger program working.

Thanks in advance, i've been pulling my hair out.

Serial Communications: Sending And Receiving

I'm currently writing a VB program to send and receive data out of the serial port using the MSComm component to a chip tester. My question is, is it possible to send data out of Comm1 and to receive data in from Comm2 from a SINGLE computer or do I need 2 computers?

I have tried using 1 computer and have connected the pins on comm1 and comm2 as following:

Comm1 - Comm2
2 - 3
3 - 2
5 - 5

At the moment, I was able to send data out of comm1 but am receiving nothing in my display text box. It is not possible that the input buffer is empty so I suspect that something is wrong with my code.

Please help!!

Send/recv = Not Sending Or Receiving
VB Code:
Dim user1 As Stringuser1 = "kkkkk" Dim buf10 As Stringbuf10 = String(32, 0) sendString lngSocket, user1, Len(user1), 0recvString lngSocket, buf10, Len(buf10), 0If Left$(buf10, 4) = "blah" Then    MsgBox "ok...", vbCritical    Unload MeElseIf Left$(buf10, 5) = "blahh" Then[b]sendString lngSocket, hd2, Len(hd2), 0recvString lngSocket, buf10, Len(buf10), 0ElseIf Left$(buf10, 4) = "blap" Then    MsgBox "good"    Unload MeElseIf Left$(buf10, 5) = "blump" Then    MsgBox "Everything works..."End If[/b]

The code you see in bold doesn't work. The code above it works fine. So I take it you can't send/recv data 2 times each in the same function? or?

Any problems with any of this?

Sending/Receiving Binary Files
I was wondering if anybody would have any example code on how to send/receive binary files.
I've been trying to do this for awhile and have yet to be successful at it....

Any help would me much appreciated

Sending And Receiving Binary Through MS Outlook
I'm working on an application to read e-mail.
I have a different platform sending data through email and to conserve space I am sending the data in binary. My biggest problem is that certain charactors are used by Outlook as control codes and Outlook manipulates the data.

Does anyone know of a methode of temprarily "turning off" Outlook's response to control charactors? If not does anyone know of a email program that will do this?

I've thought of sending the data as an attachment but I beleive that too adds a lot of data to my message. I am very limited on the amount of space each message can contain, I beleive it's 104 bytes, so I would like to get as much data as possible without using up space for control codes.
For referance here are the ascii codes that I cannot receive correctly;
00, 10-13, 145-151, 160, 173.
I know what some of these control codes are, so I know what Outlook is trying to do, but that doesn't help me to receive them.
With a VB application I can create a file with codes 0-256 and read the file back correctly so I am pretty sure it is the email system that is createing the problem.

Sending From MSComm And Receiving From Winsock (VB)
hi all,

i am trying to send a text file through mscomm control to a device (MCU). the device then sends the text file back to the ethernet card. here i have used winsock control to receive data.

when i send data through winsock and receive in com port the text file receives properly, but when i send file through com port and receive through ethernet the text file is garbled. the code works partly for Unicode files but returns only garbled characters for ANSI file.

receiving through com port

Code:If link.PortOpen = True Then

    Select Case link.CommEvent
    Case comEvReceive
        'link.InputLen = 0
        If Ret1 = 5 Then
            'Open temp1 For Output As hLogFile
            Buffer = link.Input
            ShowData hidden, (StrConv(Buffer, vbUnicode))
            Buffer = link.Input
            'Debug.Print "Recv : " StrConv(Buffer, vbUnicode)
            ShowData rstext, (StrConv(Buffer, vbUnicode))
        End If
    End Select
End If

receiving through ethernet

Code:If term.State = sckConnected Then

If Ret1 = 5 Then
    term.GetData Buffer
    ShowData hidden, (StrConv(Buffer, vbUnicode))

    term.GetData Buffer
    'Debug.Print "Recv : " StrConv(Buffer, vbUnicode)
    ShowData rstext, (StrConv(Buffer, vbUnicode))
End If
End If

i store the data temporarily in a textbox and then save it to a file when a button is clicked

Sending And Receiving SNAP/Ethernet Packets
I am using VB6 and I want to send a SNAP packet (802.2) to a defined desitination (MAC address). My question is simple: how do I accomplish this?

A SNAP (Sub-Network Access Protocol) packet looks almost like an ethernet packet. If I am correct, this protocol is located below the TCP/IP stack. I have browsed the Internet for a solution and what I found was that I should use the WinSock Control and set the type of the socket to SOCK_RAW (raw socket). This, however, is not possible; the type can only be initialized with TCP or UDP. When using the Winsock Win32 API I can create a raw socket. But when I examine some sample code I somehow have the feeling that I am still on top of a TCP/IP stack because they require for instance an IP destination address.

Ok, attempt number 2 concerns WMI. I saw that when using WMI I can query my computer what NICs I have (I have a wired and a wireless NIC). But I am wondering if I can address a NIC and send a packet to it which the NIC will handle properly. I haven't found any interface to the WMI-COM to do this.

Again, what I want is this:
1) create/define a packet and initialize all required fields like MAC destination and source address.
2) present the packet to the ethernet driver (directly or indirectly?!?) to transmit the packet.
3) configure a listener for any receiving packets.

Can somebody help me with this problem; any link to sample source code will be very appreciated.

Receiving Data From Com 2!
I am trying to use a weightbridge system, that connects to com2 at 4800bps, even parity, 7 bit
data, 1 stop bit and hardware flow control (4800,e,7,1,r) and the
incoming data is in the format:

3 39840 kg 13

( weight ID of weighing)

I don't know what the 3 is for.

The data is sent when the record printer prints (IE: when print is
pressed on the display unit)

How can i make the ID and Weight appear in fields on a form in access when the data is sent? I'd very much appreciate any help.

Receiving Data In With Winsock
If I use the Data receive Event in Winsock to get the data from the buffer how do I ensure that I have finished receiving all the data before I get it??

And if I count the bytes and it is not all there should i re-send and receive on the same connection or should i close that connection and make a new one??

I am writing a program that connects with a machine tcp/ip sends a command to it, and the machine sends back data. I seem to be getting the data before i have received it all, because if i step through 1 line of code at a time my program works correctly if I run it flat out, i never get the correct amount of data.

Thanks to anyone that can help

Receiving Data Porblem
I'm trying to receive data from COMM Port and I use MSComm control. Parameters for MSComm1 are set as follows:

InBufferSize 0
InputMode comInputModeBinary

I expect to receive a variant form MSComm1.Input and to convert this into array of bytes. Code sample is:

Dim buffer() as Byte
ReDim buffer(1024)

Using debug mode and watches I realized that InBufferCount property keeps value (for exmpl.) 23 for a few seconds and then switches to zero without moving execution to next line of code. If I move execution to next line value is set to zero immediately.
I want to see results in TextBox or in debug window but I don't know h
