I am trying to read the file contents using
System.IO.File.ReadAllText
After reading the file contents the special charaters gets replaced with some garbage characters like "?".
To eliminate this I have used encoding along with above method
System.IO.File.ReadAllText(strFile, System.Text.Encoding.ASCII)
But still it is not working.

I have managed to access and read a specific file line by line. If I wanted to split information by a comma or space and then sort alphabetically or numerically, how would I go about this procedure? Would I create a loop within the reading loop to parse the information?

I am writing an application that will call a SQL Server job on all our client's systems. I'm able to execute it, and wait until it's finished. It has an output file that's save location is hard coded into the job however, and this is not the same location on all client's.
Since the job is identical on systems minus this one value, I want my code to read in the script of the job and parse out the location.I'm having trouble figuring out how to get the actual text of the job itself.
Is this possible in .NET? If so, how?
I am building a program to populate an Excel invoice template. The program works for the most part, except for one odd flaw. The program calls a module which first checks that two text boxes on a form have been completed. However, whilst the program does see when one of the text boxes has not been filled in (txtContact) it doesn't see the other (txtCustomer) even if I change the name of the text box to check it still only responds when the the other text box is empty.

I am having an issue with serial port timing when using it to read large flash content. If I slowly step through the code the program works as expected. If I let it runs by itself it only shows part of the result. The problem is not related to displaying the data on the form but mainly the "Serialport.BytesToRead".
Here is the code

I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.

Not sure what I am doing wrong here but I have 2 buttons and a rich text box. The issue is when I click the second button to add text to the rich text box and it over writes the current text that is already in the rich text box. How can I code this second button so that the text is added to the rich text box and not replacing the current text?

I have a form called 'Bookmarks' that loads a bookmark file that contains a single word on one line. I have put buttons on the form for sorting this list, deleting items and changing the character case to lowercase, uppercase or Sentence Case.Now, deleting and sorting the list works fine, but when I try to change character cases,nothing happens. I started the debugger and found that my case changing code does work, but the listbox doesn't seem to update it's contents.I tried listbox.Update() and listbox.Refresh() but that didn't work either.

I started programming in VB2008 couple of weeks ago (I'm using the express version) and I'm getting stumped by this ridiculously simple problem. I am trying to retrieve varying parameters from an external application and display their values in real time on a windows form control e.g. a label or text box. I already know what class and methods to reference for that, however I can only display instantaneous values (unless I use a .click event handler, but thats foolish I want them displayed without my intervention) I tried writing a loop in form load event handler but that prevents the form from loading. I also tried a loop in another module but that doesn't work either.

How can I read the file that was saved back into the ListBox?

Example I have 4 textboxes named textbox1 to textbox4 When the code is run the output in richtextbox1 is textbox4textbox3textbox2textbox1.

View 4 RepliesI have a basic math test program, and 2 forms to allow the user to choose which function to test on.
The first form has a list of radio buttons with the 4 basic math functions and a button to load the next form.The second form contains this code on Load..
[Code]...
frmOptions has 4 radio buttons, addition is default chosen.After selecting one, the user clicks a button to open frmTest.The above code runs upon first load to change a label to reflect what was chosen on frmOption above.
On step 3, the label on frmTest that is supposed to be changed based on the Checked radio button from frmOption never changes. It doesn't even change on the first load of the form, so I think something is wrong with the Checked property of the radio buttons.
I am having some trouble with some data I want to display on a form. The data is in a 2-D array, call it myarray(x,y). My attempts to display it have so far not worked. Similarly, I also need to read this data from the form back into an array for further calculations.
