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.

View 5 RepliesI 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.

View 3 RepliesI 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.

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'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'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).

View 11 RepliesI need my application to do some fairly simple C-style curly brace text parsing. The text style is similar to C or C# in that it uses curly braces to define blocks of code.[code]As you can see it also uses C-style comments (//) and can (actually always will) use nested blocks, but only up to one level of nesting is allowed. As you can also see, the code does not have to be formatted neatly. There can be spaces before any opening or closing brace and it will still be valid.The text however is not similar to C or C# in a few ways:
- it does not need a semicolon ; after each 'statement' (abc, def)
- the block names will always consists of one single word except for the possibility of comments behind that word.
- the event names may contain more words
- the block and event names do not end in parentheses ()
I am telling you this because I have a C and C# parser which I can use (it came with the text editor control I am using) but it does not recognize the language I need as valid C or C#, because the block names do not end in parentheses, and the commands are not ended by semicolons. Therefore it keeps doing things wrong (it should automatically outline the text, auto indent it, smart format it etc) because it is expecting C syntax exactly, and it sees my language as loads of syntax errors (missing semicolons etc).So, I need a way to parse the language manually, and it needs to be pretty fast too. Some of the things I need include:
- Getting an entire block (including nested blocks) just from the block name (identifier?).
- Getting all block names (nearly had this working with the help you guys gave me but not completely there yet).
- Getting all event names in a specified block.
- Getting an entire block (or just the block name) just from the current cursor position (if the cursor position is somewhere in block2 I should be able to identify that and return 'block2').
- Probably more...
Then I thought, wait a minute, this C-style language is probably the most used language style, so there should be LOADS of examples online... So I started googling but did not find many relevant things.Is there anyone who has any knowledge about simple language parsers? Anyone who can help me do the things I wrote above..? I realize I am asking for a lot, but the language is pretty easy and I cannot imagine that it is extremely hard to parse it quickly. I also don't require any syntax error checking; all I need are the few things above (mainly retrieving the block names and event names).
