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.

View 5 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.
Text Data To Table

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).

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.

View 6 RepliesOur application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"
View 1 RepliesI have a design question about parsing data in Silverlight. I need to allow my users to validate their csv data (they paste ten rows into a textblock), but I am not sure if I should attempt to do it on the client side where I don't have access to the textfileparser class or send the data to a webservice for validation. If I send it to a webservice how do I ensure the data is secure?

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?
