I'm toying with an idea that would require me to parse a text file that contains a SQL statement. (i.e. Select * From Customers) I would like to be able to programmatically via Visual Basic identify key words, table names, comment lines, etc.So, how do compilers handle such a task? How does a SQL database handle such a task? All of the parsing tools are for CSV files with some sort of consistent delimiter. I'm wondering if I need to read the file one character at a time and then do some sort of comparison.

I'm trying to parse a text file. First I plan on extrcating each line, then extracting each field by searching for a tasb.When I use InStr to search for a (return for end of line) or (for tab) I always get a zero. But if I put in a visable letter such as a I got a 5.also I tried /r, /n and all return a zero.The file looks as follows:
ID Name
1 Patient
2 Bed
3 PatientSet

I was wondering if anyone knew of a good tutorial for parsing data from a text file and then populating the data into multiple text boxes. I have a text file with information pertaining to my form. The text file consists of key identifiers for each piece of information needed and I was wondering how to programmatically fill in my form by parsing that data.

I'm using visual basic 2008 express to do some simple stuff. For this project, Im reading in one large text file.The top of each page has a header section that is always the same, except sometimes a dept# changes, signifying a new set of data.The first line always has the text "RunDate", so when I read that, I know that I'm at the top of the first page.After reading the first line, I'd like to immediately go to the sixth line and grab that dept# and store it.dept = left(trim(myline,7)(Its always 7 characters long) so I know what dept I'm working on.I'll then loop through and write each line to a new text file, until I hit the top of a new page.At that point I need to look at line 6 again. if the dept # is the same, I'll keep writing to the same file.Reading and re-writing from the text files is easy, I just loop through line by line, but I need to be able to jump down to the 6th line, and I don't know how to do that without reading each line to that point"

I would provide my code but I made it so complicated I don't really want to show it. I want to start over.I would like to create the most simple way to begin parsing the text file below beginning with the line - 1, EVENT parsing this comma delimited portion.I would like to
1. NOT include the comments and
2. NOT parse the Array1 and Array33 portion of the file
3. Put it into a collection based on the AlarmLog class provided below.

I'll start off by saying I am using Visual Studio 2008 Standard. I am creating a program that will open installed programs using short code. For instance, if a user types in 'npp' then Notepad++ opens. I have it working just fine to respond to the predefined commands, but I would like to expand it so that the user can define their own settings simply by typing the program directory and the custom short code they want: Example: If I am an end user and would like to say define a short code for Windows Media Player, I would simply type the following: (Assuming Excel or likewise is used to open the csv file).

I have a piece of code in my application that is giving me a funny result. I am reading a text file and based on it's first word on the line I have a bunch of IF statements that then assign the value to a variable.
The problem is that not all the if statements are being met, well they are but that's what's weird.

Im trying to parse a log file and display the data in a textbox.The log is forever changing so it will have to be some kind of a loop.I only want the new data to be added to the textbox after the application is running, not the contents already in the log file.

I am using Streamreader to read a text file containing data such as the following:
IN;SC;PU;PU;SP1;LT;VS10
IN;SC;PU;PU;SP1;LT;VS10
PW5;PU4179,27448;PD4179,29951;PD3244,29951;PD3244,30286;PD5494,30286;PD5494,29951;PD4555,29951;PD4555,27448;PD4179,27448;
The final goal is to use the numbers next to the PU and PD characters to perform specific calculations.
Essentially, I think the code needs to do the following:
1. Read each block of characters ending in a ";"
2. If the block commences with anything other than PU or PD, discard it
3. Extract the numbers in such a way that calculations can be performed. The following is an example:
x y
PU4179,27448;
PD4179,29951;
[Code]....
Essentially, there will be hundreds of these rows and I will need to sum up the deltas so that a specific formula can be applied.
I have tried doing this a number of ways but each seem very inefficient (using text boxes to store/swap data and creating additinal text files are 2 methods I have tried) and so I'm looking for some direction.

in vb, you can use text which is in textbox instead of numerical expressions. I mean, if I write 50 in textbox1 and also I can write like that code:
Dim result As Double = TextBox1.Text + 0.4
as you see, I didnt convert any type but it works in vb.net
But I want to learn what are disadvantages of this using?
(I am just talking about arithmetic operations)

I am attempting to parse multiple lines of text from a text file using regexpressions. I am using vb.net with visual studio 2008. At the moment I am filling my datatable with the text file information and am able to return each line of text and parse the first set of numbers that I am attempting to break up. I have multiple string with varying lengths of character lengths and numeric lengths however the delimiters are sometimes different. Sometimes will be whitespace and sometimes will be whitespace and chars. But is always 2 spaces. Here is my code:

I have a rich text box full of encrypted data split by ";" and I have
Dim Pass, Data, Game1, Game2, Key1, Key2 As String
Dim PassEnd, Game1End, Game2End, Key1End, Key2End As Integer
Data = showencrypt.Text
PassEnd = InStr(showencrypt.Text, ";")
[code]....
Pass gets decrypted ok, and Game1 gets decrypted ok. Key1,Game2,Key2 are all the same as Game1 though. Is there something I am missing? Why is it setting all of them the same? I've tried settings the Start of the InStr's at the previous End but it doesn't work.

I'm a PHP/MySQL/HTML guy, but in the course of my work, I sometimes have to delve into Gatesland.I am working in VS2005 developing reports, and occasionally I have to write some custom code. This code is in (I believe) VB.NET. I avoid this as much as possible. It is my belief that if you have to use custom code in a report, you're doing something wrong with the DB, or with your query.Now, my boss (for reasons unknown) is storing data in the database as HTML. This data is historical, having a month and a dollar amount, and comes in a form like this:[code]I know this breaks even 1NF. I did not design the database. I simply must suffer under it's schema. See, the developer did this so that he could just read in a field, and dump it straight out to an echo/print statement when forming up the HTML. Unfortunately for me (the report developer), HTML shows up as verbose text if I dump it out as a field in a text field in a VS2005. So, I need to strip out he HTML tags, and replace them with appropriate values.
I am first trying to strip out the <th> data, and print it out with appropriate line feeds and carriage returns. This is the code I am trying to use:[code]Now, far from doing what I intend it to do, it simply returns the jubilent result "#Error". Wonderful. I'm sure the client will be happy.There must be some simple syntax errors or something going on there, but I am nowhere near an expert with VB.NET. I've used VBA extensively, but last time I used it was about 3 years ago. I'm hoping I can cash in some of that positive rep I've got, and get some much needed help in the dark wilderness of Microsoftia

Im new to VB and am working on a program for work using functionality to replace the use of hyperterminal and excel macros to dump data from a plc to a spreadsheet. I have the program setup and dumping the data to a rich text field, but this is about as far as my experience will let me go. So here are my questions:
1. Im wondering if it would be possible to use the text parsing method to sort the data into fields by first using a comma to delimit the fields and then tab (not sure how to put it as a character) to start a new line. this will then be displayed in a data grid view and later form there dumped to an excel file. i was also looking at the serial port functionality to see if it could parse too, what would be the best way to go about this?
2. I also need to be able to open more than one instance of my program and load connection settings into it (like what can be done with hyperterminal). Im wondering if it would be possible to use the save dialog to allow the user to save the settings to a file and open the settings file when launching any given instance?

I am using SendKeys to send out some text using;
Dim pText As String
pText = txtPost.Text
SendKeys.Send(pText)
Whenever I use symbols like ')' it will fail as it cannot parse it. How do you get around this?
