problem is when i enter any letter in the alphabet in textbox1 it gives me an error but when i enter any number on it, it goes perfectly to the database. i set the data type into text(all 3 of them). the other two textbox work just fine. textbox1 is the only problem.
i just want the textbox1 to accept any input not just a number like the other 2 textbox work..
heres the code:
Imports System.Data.OleDb
Public Class Form2
Dim cn As OleDbConnection

I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.

I need to control a device with a GPIB port. I have the commands that I need to use to do this; but I don't know which is the sintaxis in Visual Basic.
For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data

I've code this code below:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim hwrRequest As HttpWebRequest = HttpWebRequest.Create("http://www.example.com/web-service.php")
[Code]....
The MsgBox() at the end shows the response, which as I've added to my script, echos the result from the $user and $pass variables which are supposed to retrieve those details being written to the stream above, but they show up empty.
I'm retrieving those values by doing: $user = $_POST["user"]; $pass = $_POST["pass"];

I'm having a heck of a time figuring this out, the tutorials I found on the web are not complete or are for VB 6.0 (obsolete in some cases). On the C++ side I have the following ::
hwndExternalApplication = FindWindow(NULL, L"Dromocast Client");
SendMessage(hwndExternalApplication, WM_SETTEXT, NULL, (LPARAM)"Hello");
"Dromocast Client" is my visual basic application, and I checked to make sure it's not NULL. In fact I get made sure I'm getting some data on the VB side. On my Visual Basic side I have the following
[Code]...
When I send the data over it's garbage, meaning strTemp comes out as all these chinese characters, and my title bar on the visual basic program gets garbled with a bunch of chinese characters as well. My guess is my "SendMessage" is written wrong, or I'm doing something silly, but I have no idea what. I'm not a windows programmer so I'm kinda trying to figure this stuff out by googling.

I am currently writing a visual basic program that gets data from a serial port. everything is connected up but the data is not received until my device on the other side is turned on on the other side. which condition can i use in my loop to ensure that i only start comparing when i have started to receive so that my loop will not hang as there is no data input?

Currently I had write a simple VB code, my aim is when i click "Forward" button then the vb will send a character "A" to PIC, "Reverse" button will send "B" so I write my vb code for sending as below:
Dim Forward As Char = "A"
SerialPort1.Open()
SerialPort1.Write(Forward)
For the receiving part, after I received the data from PIC then I will show it at the label which act it as a screen. the receiving code as below:
SerialPort1.Open()
receive = SerialPort1.ReadChar()
If receive = "A" Then[code]....

i have a similar question so i thought i might post it here rather than clutter the place with a new thread, if that's okay.first off, i'm using VB 2010 Express, if that makes any difference.second, i'm trying to send data to form2 from form3 rather than the other way around. i'm still pretty much new to VB, but have a lot of experience in PHP and some in java. i'm making a basic program that creates critters on form3 and then adds them to a table on form2.[code]then adds a value of 1 to the progress bar (i still am trying to figure out how that works) on form2.

I have a program that I collect data using a com port. I display that using special visual controls - no problem here.
What I would like to do is to send this same information out over the network via ethernet to another PC located in another room.
I presume I would have to have another copy of the program on the second pc as the information is simply duplicated but I am not sure how to get the data out of one to the other

I'm creating a search form using an asp:button control with the urlpostback set to a results page. The problem is, the asp:button uses Visual Basic and the search results from Google require Javascript.
Is there a way to take the data from an asp: textbox in VB and then send it to another page that uses Javascript and use the data?

Given the following information
Public Enum Request As Byte
None = 0
Identity = 1
License = 2
End Enum
Protected mType As Communication.Request
mType = Communication.Request.Identity
Debug.Print (BitConverter.GetBytes(mType).Length.tostring)
2
Why does bitconverter report that mType is a length of 2. I would have thought that passing a Byte into BitConverter.GetBytes would just return the Byte. I mean it's no big deal because it's only sending a very small block of data across a TCP Socket, but I'm just intrigued why it thinks it's 2 bytes.

I have been using RSACryptoServiceProvider and was using the template code provided from the MSDN resource page.url...I wanted to encrypt the data on my computer and transfer the data to the FTP server and have it decrypted there. I have the encryption and decryption code but it is in the same program and only work during the instance it is open. The intention is to have a program that will encrypt and send the data to the FTP Server. There will also be a VB Script on the server to decrypt the data and store it in a separate location. How do I get it to store the public key on my computer and the private key on the server? Also, how to I transfer the encrypted data over to the FTP and have it saved there?The purpose of this project is that we have people located over the globe and are sending sensitive information to an FTP server at the home office. My boss has insisted on the data being encrypted before sending anything. But, on the server it will be decrypted so that a select few can go through the information.

How i can send data from one form to another form through a network? i'm not asking for the codes, i just want to know what i should do to accomplish this task. i'm conceptualizing a game with the following details:
1.) there are two players, connected through a network
2.) they take turns looking for words from a puzzle of randomized letters
3.) after the given time has elapsed their words are checked and if both players has the same word, the word is removed
4.) the score is tallied
My question is, how do i get the words from the other form? specifically, how can the server form get the words from the client form? is it possible if i use xml? or can the server form access the variables of the client form? (i don't think it can, though)

What I need is, a program will be distributed and the customer fills it out and such, clicks submit, and the data is sent to the company. I want to avoid using SMTP since not all consumers will have it set up. Is there anyway where this could be done, for the general user? I've spent the day thinking, but have no come up with anything.
The code, to send the info out, will just take the data from text fields, and sent it to either an email (hopefully not) or a place where the company can view it.

I am trying to send a command through my serial port to a external device. The format of the command frame is, more or less, like this:
'0x0A 0x03 0x20 0x00 Checksum'
What I've written on my code is just this:
VB code
num_dec = &HA + &H3 + &H20 + &H0
checksum = DecToHex(num_dec) '2D
data=&HA & &H3 & &H20 & &H0
SerialPort_RFID.Write(data & checksum)
The problem is that when I stop the program on the Serial...Write line, I see that the data I sent is on integer format instead of Hex format.

I am having trouble sending data to a comport..... I am a noob at this and have been doing my head in... I have done a fair bit to a few programs that I have on the go, but am stuck at sending some data to the comport...
I have in form1 put the serial port contol and added SerialPort1.Open() to that. I have then added 3 buttons that I was to use to send data to the port... Since this is for a radio scanner the buttons turn the backlight on / dim and off.....
LTN is used to turn the light on and works fine in hyperterminal.. I have got the port settings right in vs2008 but the code is wrong.
I have:

I'm using an Asynchronous Method to send data across the TCP Protocol. For the most part it seems to be working, but recently, I've been getting results that have missing bytes to them. How am I actually able to figure out what's missing on the sender's site and make sure all the data gets to the end? For example: my end client receives 1408 bytes of data when I sent 1532 bytes. I sent an array with a length of 1532 and the client only got 1408.
