Stream Reader / Writer - Illegal Characters In Path
Apr 28, 2011I'm trying to setup a simple app that reads a file and then writes the contents to another file using OpenFileDialog and SaveFileDialog. Looking at the debbugger it looks like it's reading fine, I can see the data I want written. Towards the end of my code I get the following error message:"Illegal characters in path". I've researched this error. I'm not using any illegal characters such as /\? etc and the pathname contains all alpha characters. I'm pulling the test file from the C drive and trying to save it there as well.

Stream Reader And Writer - Read Data From A File
Jan 27, 2009I am trying to make my application read data from a file. Then save the data back. However I keep getting an error which says the file is still open so cannot be edited.

Heres my code so far!

Stream Writer / Reader - Modifying Time Intervals
Apr 28, 2009I am new to Visual Basics and I am using Visual Basic 2008 express. I have been using video tutorial on line to learn VB and they are great in explaining what is happening the code vs. just looking at code. I think from what little I can find I would be using StreamWriter WriteLine and StreamReader readLine .I am using a couple of forms. I am looking for simple basic code to use a form as a way of modifying timer intervals and store the values in a single text file on separate lines.
Description:
Form1: will contain the main code that will run. It will contain some timers. I want the timers to look in a text file for their intervals. Each timer would be on a different line.
Example:
Timer1 interval would be located on line 3
Timer2 interval would be located on line 6
Timer3 interval would be located on line 20
Form2: will contain 3 textboxes. This is where when I load form2 I will also read the same values from the text file to preload the text boxes. I will now be able to change the timer intervals as needed and press a button to update the text file. The update button will also reload the new timer settings on Form1. This is very similar to how a CNC Machine works with Parameter settings. This can be useful for storing many different settings for a form that a user can modify and be stored and reloaded next time the program runs.
VS 2005 - Reader And Writer For Favorites In Browser Application
Oct 19, 2010I'm making a browser and for the favorites I'm using a reader and writer to read and write new favorite to a .txt file. Now if I edit the text file manually and load up the browser, the favorites show up as they should but the problem comes in when I add the a new favourite and then reload the application. Once reloaded the favorites seem to copy what was originally in the file and then whatever I added last at the bottom.
Here is the
Public Class Form1

VS 2005 Strea Reader/Writer Delete Line
Dec 6, 2010I have a program that reads a text file tab delimted using OLEDb .I need to be able to allow the user to insert a user created record into the file which I can do.
The problem is I need to be able to let the user edit that record. From my understanding you can not edit or delete with OLEDB only insert So I thought I would read the file using stream reader, find the line I want to edit and just delete it, rewrite the file, then let the user insert a new record
If someone has a better way to perform this operation I am open its just the best way I could find with my limited knowledge and the reading and researching I have been doing thus far.
So I am trying to step-by step and first read the file which seems to work then find the line that would need to be deleted. So I was trying to use the
line.startswith method. I am using msgbox to see if that works before I continue but it doesnt seem to work I know my file has several lines starting with "Active" but my msgbox returns "False"
Here is the code I have so far

.net - Inter Process Reader Writer Lock (or File Handles And Access Denied)
May 8, 2009We needed an inter-process reader/writer lock.We decided to use a file and lock the first byte using LockEx and UnlockEx. The class creates a file in the system temp folder when it is created. The file is created with readwrite access and share read|write|delete.We also specify DeleteOnClose so we don't leave loads of temp files laying around. Obviously AcquireReader and AcquireWriter call LockEx with appropriate flags and ReleaseLock calls UnlockEx.We have tested this class using a small application that you can run several instances of and it works perfectly. The application that uses it has a problem, which we have managed to re-produce in another small test app. In pseudo code it is
Create InterProcessReaderWriter
Dispose InterProcessReaderWriter without acquiring any locks
Launch a child process which takes a reader lock
The first time this runs, it works fine. If you attempt to run it again, while the child process from the first time is still holding the lock, we get an UnauthorisedAccessException when trying to open the file.This appears to be a permission issue, not a sharing violation but all the processes in this test case are running as the same user.

Mar 14, 2010I am trying to use the eID SDK (for using the belgian ID-card) in VB. It's supported but I can't get it to work. I have never worked with sdk's before. I did manage to get it to work in c++ in console but I really need it in visual basic. Also the VB examples that come with the sdk are made in an older version of visual studio and when my version tries to convert them they don't work. I want to use the sdk to see when a card is inserted into the reader and to read out the data. (both i got to work in c++ console).

Jun 18, 2009I am working on writing a program that once a magnetic strip card is swiped, the number on the card is validated against a database storing information on the user. What is the best was to get the stream from the USB swipe card reader, build by Magtek, and then just pull the 9 digits I need? I have currently been using an Excel macro that searches the Excel document, but I want to get away from this system and make it more user friendly.

Reading ASCII Data From Magnetic Swipe Card Reader?
Sep 27, 2011We have the customers credit card number on file which we use simply to identify them when they swipe at our computer. The problem i'm running into is that when they swipe their card in the card reader (Magtek mini usb) it outputs the data as ASCII which looks something like %B followed by the credit card number in whatever textbox i have the program focused on. I'm sure i could just search the textbox for any 16 character number string and assume that is their card number, but i was just curious if there is some best practice to decript the ASCII output from the magnetic card reader.
View 1 RepliesCapture Raw Signal From WiFi Card As Would A Sound Card
May 9, 2012Is it possible to capture the raw signal from a WiFi card in the same way you can capture the signal from a sound card? (I already found code for working with a sound card and for drawing spectrograms) I'm wondering because it would make a cool radio-type project. I'd prefer a solution that integerates well with .net (VB or C#).My basic goal is to capture the ambient radio waves and build a primative "telescope" of sorts. Using the built in computer hardware is just the easiest way to accomplish this. If you have any other suggestions about how to accomplish this goal in a different way please post it as an answer also.
