Send Data To LPT (COM) ?!
My, question is: How can I send data, directly to the LPT. I mean, to control external objects (LED's for example) through the LPT. Do you know something, about the existing OCX or DLL-s.
P.S. (Info for COM port will be useful too)

How To Send Data With Multiple Data Types(different Everytime)
I am sending some data to an external USB device. This data contains ID + Parameters. ID should go as a hexa string and paramters should be sent as Hexa value(0x0000) having different data types (like long,byte,integer data type)
So, If i have Data like "dA2302" should be sent as
"dA" = hexa string - String Data Type
23 = 0x23 - cByte(&H23) - Byte Data Type
02 = 0x02 - cInt(&H02) - integer Data type
In USB API i can send this data using any object (could be string,long, or any structure object).
But, My Question is.. Everytime My Data can contain different number of parameters, different data types with different order. So, How can i send these multiple data type values in one object in Visual Basic?
Please Help.. Thanks
TCP/IP - Send Data/recv Data.
I trying to connect as following, and i see i am connected to the server. But i dont receive anything, the manual told to send me data as following, can anyone give a sign what type of string or varialbe to be used here, and what could be the value, i realy need to send so that atleast i see i am doing correct?
Manual for interconnect TCP/IP:
1. packets on the tcp socket are always 256 bytes long, they contain one or more primitives, each primitive has a type octet and a lenght octet. A primitive can have fixed size fields and vairable size fields. When a field has a variable size, the first octet of the field always contains the size of the field excluding the length octet.
2. Option mask format to send to server for getting responce explain in manual.
3. Please check the attached file.
Length=108 or 60
001:ip address 1
010:ip address 2
set to 1 if need
bit 7: set to 0
---- my code i am trying.....
Code:Private Sub Command1_Click()
If .State <> sckConnected Then
If .State <> sckClosing Then 'Sometimes the Winsock gets delayed in the closing state, so make sure it is closed before trying again
If .State = sckClosed Then 'If closed, ok to open, else close it ,Start 5 second count
.Protocol = sckTCPProtocol
.Connect "one1.one.com", "5900"
Private Sub Winsock1_ConnectionRequest(ByVal requestID As Long)
If Not Winsock1.State = sckConnected Then
Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
Winsock1.GetData gbIOBuff, vbArray + vbByte, bytesTotal
Text1.Text = Text1.Text & gbIOBuff & bytesTotal
Private Sub Command2_Click()
Winsock1.SendData Text3.Text + Chr(13)

I did read some of the stuff on winsockvb.com.
But with no sucsess.
Well i make my game in Visual Basic 6.0
With winsock. I have a current players list in my form.
i want the Client.exe to send a msg to the server, and for the server to add a item in the listbox on the client?.
how can i do this?, you have any Tutorials or sutch?
Thx for all the help
I am trying to make a program and their is a section where i want the user to do import on what they think about it and when they fill it out and and hit Submit the infomation they entered is Sent me can someone please tell me what Componets i have to use etc....
I need to come up with a method of sending data in my turn based game. I'm a noob to winsock but I have the connection stuff down and get sending text but I need to make sure when I send other types of data I come up with a way of doing it that will work.
I've looked around a lot and gotten some useful info but I'm having trouble with the very basics of sending data/receiving it.
I am using a central server and multiple clients, where a client sends info to the server and it is then sent to either multiple clients or a single.
Anyway, how might I send say a boolean from a client to the server and back to a single client?
Like OnlineGame(ArrayNumber) = true for example?
Do I make up an arbitrary string like StrExample = "Test" if OnlineGame = true? And then send the info to the server? Like Winsock.SendData StrExample and then receive it on server with DataArrival? And use SelectCase StrExample = "Test" then OnlineGame = true? And then pass it on in same way to Client?
I need some kind of working sample. I see all the Splitting and packet delimeters and DoEvents and I get what they do but I can't put it all together for my game and what I'm trying to do for my specific game.
Any help would be appreciated. Thanks.

Which Data? And How To Send With MScomm....
Hey all, posting in hope to see if someonw could point me in the right direction.
I've just began to learn VB 6 (from books) and have no other previous experience with any other programming langauge.
What i'm trying to do is send the appropiate date to a microcontroller, the problem i'm having is, I don't know which data i need to send, or how to send it...
Here's some info on the APIhttp://reprap.org/bin/view/Main/Step..._a_single_step
I belive the original program which was used was Java, but i presume i should still be able to send the data i need with VB if i could just figure out what data to send and how to send it.
I'm not looking for anyone to write the code for me, just someone who could maybe point me in the right direction as i've searched and read page after page without any progress..
P.s. If anyone needs any more info just ask and i'll help all i can.

Data Stream Send
I am trying to jury rig an application within our institution and I really don't know what to do at this point. Basically I have a data stream (effectivly a .txt file) that needs to be sent. The applications we currently use (which aren't cutting the mustard) send to a port and IP address. Effectivley it somehow sends this information to a specific IP/Port address and there is a handshake which accepts it. I have absolutly NO idea how to send this information or even where to begin since I cant ask the vendor (since I'm stepping on their toes).
Any suggestions would be greatly appreciated.
WriteFile API To Send Data On LPT
I have a problem with spoolsv.exe whic make a cache to all the data which i send to the parallel port.
For example ,i have a routine like :
Private Sub SendDataToLPT()
myHandle=CreateFile("LPT1", GENERIC_READ Or GENERIC_WRITE, 0, ByVal 0&, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, ByVal 0&)
WriteFile myHandle,Byval "AAA",3,NrOfBytesToSend,0
WriteFile myHandle,Byval "BBB",3,NrOfBytesToSend,0
WriteFile myHandle,Byval "CCC",3,NrOfBytesToSend,0
...so i need to send 3 time than 3 bytes but spoolsv.exe "catch" this data and send to LPT1 all 9 bytes once.In fact, instead to send :
spoolsv.exe send "AAABBBCCC".
Please, if have someone any idea how can i solve this problem.
Fatest Way To Send Data ?
Well there are a few options and altough there probably won't be that much difference in speed transfer between them i'd still like to, for fun, find the best set of inputs to use. For starters i have the choice of
TCP/IP or UDP ?
Then i can use either the,
1) Winsock control
2) A class API wrapper for the winsock control
3) Pure winsock API(not entirely sure how this differs from 2))
4) I can also use winsock 2.0
So what is the absolute best combination to use for a P2P file sender ?

Send Data To Two Sheets
I would like to know if it is posible to send data to two sheets inside the same workbook? Do I have to like "activate" the sheet before sending the array. Basicadlly I want to send "raw" data to one sheet and some calculated "data" to the second sheet. This is the code I have try:
Private Sub Command1_Click()
Dim Absorb(1024) As Long
Dim o As Excel.Application
Dim oWB As Excel.Workbook
Dim oWS As Excel.Worksheet
Dim Limit As Integer
Limit = ebNumTracks.text 'Gives the # of Tracks
Set o = New Excel.Application 'Opens an Excel instance
Set oWB = o.Workbooks.Add 'Open Excel Workbook
Set oWS = oWB.Worksheets("sheet1") 'Add WorkSheet
Set oWSS=oWB.Worksheets("sheet2") 'I add this for using 2nd She
o.Visible = True 'Make Excel Visible
Picture2.Cls 'Clears the pic box
o.Sheets("sheet1").range(o.Cells(1, 1), o.Cells(1024, Limit)).Value = aData() 'Put data on Excel
List1.Clear 'Clear Listbox
For j = 1 To ebNumTracks.text 'Plot all tracks
List1.AddItem "Track#" & j
' GetRowCCDData (j) 'Get the Row data
Picture2.CurrentX = MinX
Picture2.CurrentY = MinY
For i = 1 To nXPixels Step 10
Absorb(i) = aData(i, 1) / aData(i, 2) 'This will determine the column difference
Picture2.Line -(i, aData(i, j)), QBColor(j - 1) 'Plot lines 'Pulls from aData
' Picture2.Line -(i, aRowData(i)), QBColor(j - 1) 'Plot lines 'Pulls from GetRow
o.Sheets("sheet2").range(o.Cells(1, 1), o.Cells(1024, Limit)).Value = aData
(In this case I try to send the same array to the second sheet because I was just testing it)

How Do I Send Data From One Datagrid To Another?
OK, a little hard to explain so bare with me.
Anyway, I'm writing a program for a friend thats opening a shop. The program retrieves the data from a database full of his product/descriptions/stock/prices.
I've set up a datagrid that displays this info. What he wants to do is to be able to dblclick a row that contains all the above info for an item and add this to a temp. shopping list.
I've thought of passing the row he selects to another datagrid, adding to it dynamically. The thing is, how do I go about this? I've got the database running perfect. He scrolls up and down the product datagrid a row at a time, but I haven't a clue on how to pass the selected row to the new datagrid.
I hope I haven't confused you.
Thanks for any help.
