I am currently developing a program that can read text to audio, I know there are already thousands of software out there but it is not in my country language. Now I have found a way to invent a similar program with high quality audio, text exchanges to wav file, and I made every word a wav file that corresponds to the word, I could type text into the textbox then I could read the corresponding wav file.
my problem is being able to highlight text while reading the text box, for example: type in the textbox: HELLO MY NAME IS JOHN, NICE TO MEET YOU. WHAT'S YOUR NAME! when read and mark the same time, if there are similar words in the previous line, then jumps back word marks and ignore next word. In our examples there are two words like: NAME, when read and mark it read and select the right until it reaches the next NAME and instead marked the first, then continues. If there are several words that are in the text, always highlights of the first word.
in directory C:Audio there is those word as wav file EXAMPLE: HELLO.wav + MY.wav + NAME.wav and so on. I do not want the mark back, i want it to select those who are not selected.
I've setup a TextWriterTraceListener which outputs the debug messages I've written to a file.This works fine however what I am trying to do know is output the content of this file to a textbox using a streamreader object.I originaly thought it may because I did not set the text file to allow read/write access so I changed this by setting the following:[code]
View 4 RepliesI've a got a homework assignment that chooses one of four values in a list box, stores it in a text file. Secondly, on the display click event it should access the text file, read the line, store it in a variable and then display the totals in a text box. Works sort of fine except that it doesn't display the totals correctly. Code for both buttons is below. The variable are assigned in the mainform (Tried also in the display button and didn't change anything). The save button works fine and stores fine in the text file, it's just the reading that's the problem.
Private Sub saveButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles saveButton.Click

I'm creating a program where the user has to input Name, and Number Of Pieces Made, then depending on the number of pieces a calculate is done called AveragePay. The can enter as many as they want. Then I have Name, Number Of Pieces, and AveragePay all displayed in a listbox. Now when the user clicks a button at the bottom, it needs to give them the TotalPieces, and TotalAveragePay. Now the problem i'm having is I'm not sure how to read from the listbox and get the Total's from there. If anyone could guide me in the right direction please.

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?

I am using VS2005 version of VB.Net programmer. I wanted to use the user input but most people tell me to use console...but I cannot use this function since my version is different, it will not show any results.

I want user to input two number such as 1.345 and 2.355 and use this number for addition and give the answer. I not sure how I write the code for mask textbox to be read once user input the numbers.

I want to perform two hashing operations concurrently on a single file, without reading the file twice. Is there some way to share the FileStream between two synchronized hashing threads? For example:
Dim Stream As New IO.FileStream("...", IO.FileMode.Open)
Dim HashA, HashB As Byte()
Dim A = New System.Threading.Thread(Sub()
[code]....
Maybe some way of caching a stream? Trouble is, I don't want the entire file in memory at once (it could be many gigabytes in size) and I don't want the file read more than once, due to speed issues. I want the file cached only sufficiently to ensure that both threads can work.For example, suppose at some point in time, thread A had read 100k of the file, but thread B had only read 20k of the file. The portion of the file between 20k and 100k should be cached; but then progressively forgotten as thread B catches up. Then again, if thread B is too slow, we might still end up with hundreds of megabytes being cached.Maybe thread A should be made to wait while thread B catches up. Maybe the ReadByte() function of the stream should block for a while if one of the threads is too far behind?

friend of mine has no HTML knowledge so I'm attempting to write a program that replaces certain parts of a html file to suit his needs.I've edited the HTML file and marked certain parts with "tags" like this:
#IMAGEURL1# I have a textbox where he can copy + paste an image URL and hopefully the #IMAGEURL1# is replaced with the contents of the textbox.
So can someone please enlighten me to-as how to open a HTML file (there's no textbox to display the contents just yet, I'll add one if needed), find the specified text and then replace it with whats in a textbox.
I am trying to import a TAB (NOt comma) delimited text file into a DataGridView. The following code works fine if I have a comma separated file. All I have to do is change the FMT to "Delimited".It just does not work with FMT=TabDelimited. All columns are read into single datatable column. The text file is ANSI text and I have double checked to make sure Tabs are tabs and not spaces, even exported a sample Tab Delimited file from Excel.Can this even be done using Text Driver? [code]

The application has text boxes (name, email address, etc) and I want to read information from certain lines in the text and place in the given text box.
Code:

StreamToDisplay = New StreamReader("C: esting estfile.txt")
TextBox1.Text = StreamToDisplay.ReadLine()
StreamToDisplay.Close()
Currently it's reading the first line of text (which is "[username]").
