Iteration Of A Text File In Visual Basic?
Jul 25, 2011
Ok, so I'm making a program that will read from a text file, convert each line into an array, the. Send each of those lines 1 per tick. This is in 2010 Visual Basic. Closest I've gotten is sending all at once, I worked on it over night and am slowly destroying it. Ideally, I want Button 1 click to populate the array from the file at LocationTB then start the timer. The timer should send a line at a time on the GapTB interval.
Public Class Form1
Public TextLine As String
Public MyFileName As String

I have created a simple application where I fetch questions from an Access database and store the answers to another Access database. I am not sure how many questions client would like to ask, so I can't hardcode that number.
So, column names for answers table (besides user information like first, last name and so on) will be a1, a2, a3 ... aN.
And finally the problem!
For testing purposes I have hardcoded saving first 3 answers like this:
newEntry.a1 = answers(0)
newEntry.a2 = answers(1)
newEntry.a3 = answers(2)
Now I would like to iterate through all properties based on count of "a-type" properties:
'aCount is number of "a-type" properties
For i = 0 To aCount - 1
Dim property As String
property = "a" & (i + 1)
newEntry.property = answers(i)
Next
Of course, above code does not work, it is just a pseudo-code idea that "should" to the same as my hardcoded example.
Is it possible to iterate through predefined properties of newEntry object in that manner?

I am working on a program for the Windows Mobile 6.0 system and using Visual Basic 08. I would like for the current txt file that I have, that is formatted as follows: "NOR400","277225","ZIMA 4/6 12OZ NR BOTTLES","07199077603",21.65,"cs",7.19,"pk","C4/6PK","12 OZ "
to be imported and each item in the line will be assigned to its own txt box. I have been able to load up the file, in to one txt box, but am unable to separate the items in to their own box. Should I be using arrays for this?

I've seen posts on deleting the lines from a text file that are specified as a function parameter, but I only need to delete the first and last lines from the file.
I'm still a newbie when it comes to working in files, but it seems that it should be simple to delete the first line... Just delete all text from BOF to the first CrLf character. Am I right?
As for the last line, I understand that I'll have to get a count of the lines in the text file to find it (as the file won't always be x amount of lines long).

I need a small app that randomly shuffles a set of preloaded numbers. The shuffling will be visible on the screen and goes on continuously (looping) until a key is pressed and as soon as that happens it will show the winning number.Am using visual basics 2008 to develop the application but my problem is when i start the app and hit a key it will loop through my numbers on the text file and it will also display the event but if i hit a key to stop it will not stop..I was workin on the app but my problem is how to stop the loop and resume on the with a keypress. below is the app codes.
Dim Running As Boolean = False
Sub ReadAccounts()
Dim arr As New ArrayList
arr.Add("1366-665885-666-22650")[code]....

I am writing a visual basic.net application to pass remote shell command through command prompt. I need to get the text response after the rsh command is executed. My program codes can only get the output 'C:>' text (see below command prompt window display). Is there any solution for me to get the 'Permission denied' text as well?
Program codes:
RshProcess.StartInfo.FileName = Environment.SystemDirectory & "cmd.exe"
RshProcess.StartInfo.Arguments = "rsh..."

I am reading a temperature value from a transceiver into the serial port and I want this value to change the value of a label in my Visual Basic Form. This value changes every few seconds. I am using the code below:
Me.dataReceived.Text &= [text]
where dataReceived is the label I am using and [text] is the data I am reading from the serial port. This results in the data being displayed but instead of overwriting the label, it writes the value after each other. (The data is appended). I tried to remove the & before the = but this did not work as nothing showed up.?The code I am using is the following:
'To receive data into the text field
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived

I have a web page that has a few text fields, and a reset and submit button. I'm having trouble getting the reset button to work to clear the text fields because the required field validators and regular expression validators are blocking any code in the reset button's click event from occurring. how to get the validators to not activate when the reset button is clicked? One method I tried was to set the enabled property of all the validators to false in the reset button's code block but no luck.

I am writing a math game for my brother in Visual Basic to help him with double digit numbers(both adding and subtracting).Normally you solve a problem by writing right to left on a piece of paper. Is there any way of setting the text box to do this?
For Example:
58
+ 18
You would type in the text box '6' followed by '7' so it would read '76'I set the right to left property but it does not do what I want it to do.
