Get Data From One Text File?
Nov 29, 2009
I need to get data from one text file and use it for a calculation in another text file. The first file has the students' current grade and the second file has the students' overall GPA,. I need to get that current grade(named 'qp') out of the first streamreader so I can use it for my calculation but it only gives me the 'qp' of the last student in the first streamreader.
Here's the
Public srStudentfiles As New System.IO.StreamReader("c:studentgradesnew.txt")

Our 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"

I save data from datagridview to text file. I also load the same data from text file into datagridview for edit and update the same thing to text file. Let say this text file i called as Drill.txt. I have another text file called header.txt which need to match its value with the value of Drill.txt file then overwrite value from Drill.txt to header.txt. Now i want to make my Drill.txt in encrypted format to prevent anyone to open that file and modify out of program. They only can modify it through the program

I have a text file containing ten pieces of information (5 prices and 5 descriptions) I want to load the information from the text file in to the text boxes, so that it can be viewed and edited if required.
I've declared the filename, and various variables, but I'm not sure how to get the info from the file to my form?
filename = CurDir() & "/charges.txt"
Could I use something like this:
fileopen(1, filename, openmode.append)
do while not EOF(1)

I decided on a comma separated data file, saved as a text file. This is for data that will not change. After loading the data from the text file; then throughout the lifetime of the program the data can change. The data can then be saved back to a different binary file. The idea is to have a save state system going.Does anyone have a suggestion or is opposed to the idea. Is there a simpler way to organize something like this?

I am making a simple application that will be able to store competition data into a text file that I have given a custom extension to on saving. Here is an example of the format that i have saved the data in.
Code:
[Comp_Name]Test Competition[Comp_Name]
[Location]Silverwood Lurgan[Location]
[Type]Teams[Type]
[Code]....
When i open the file, i want to redisplay the data in separate text boxes. Later on in the project i want to be able to search within the file for headings for example;
if "[Heat1]" is present then get all text between [Heat1] and [Heat1]
i am currently able to use the streamreader and open file dialog to retrieve the entire string of text fromthe however i am not sure how to go about getting the text between the headings I have used.

1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above).Include suitable headings. Note that you cannot assume that the file contains onlyresults for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
The output might look as follows:
Home Team Away Team Home Team Goals Away Team Goals
Bunbury Braves Nedlands Nodders 5 2

I have a variable (double) that is constantly update in real time with data from an analog input. I would like to write this data as it comes in to a txt file. When I stop my acquisition of data from my analog input, I should have a txt file with all that data stored on my computer wherever I want it. The way I'd like that txt file to be laid out is like so:
Test Title: "This info comes from a string variable"
Operator Name: "This info comes from another string variable"
Test Date: "This info comes from yet another string variable"
[code].....
And so forth. As you can see I would also like to write the time for each data. This depends on my Timer interval which the user can set. The default is 50ms. So by default, y1 y2 y3 would be 0, 50, 100. How would I generate such a text file?
PS: I have five variables (X, Y, strTitle, strName, strDate)

I am trying to read data from a text file which is updated regularly by another program. I only want to read the new data which will then be passed off to another device(ControlLogix 5000). The code I have thus far is below, this will read all the data, but once it reaches the end it stops. The second bit of code should send the data to the PLC. I am using VB.Net 2010

To simplify what I am trying to do, let's say I have a text file with only one line of data.
The data in this case is color info for one pixel:
Color [A=255, R=255, G=200, B=128]
What I am trying to do is read the text file and extract the hex color info and save them to their own variable.
So once the code has run, these should be the contents of the three variables.
RedData = 255
GreenData = 200
BlueData = 128
I have managed to get something to work but I know the code is terrible and is incredibly slow when I try to run through hundreds of lines in a text file.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim PixelData As String

I am brand new to the world of XML. I need to recreate a text file that used to be created by an outside app. Now we will be given a XML file that contains alot of data including the data I need to put into the text file. So I probably won't need all the fields given in the XML. Can I use Visual Basic to convert XML data to a text file?

Ive made a program that reads in data from a txt file that has 4 columns, but it doesnt work if there are headings to the columns or any other kind of text at the top of the file. I basically just want to be able to skip any text at the top of the file, either by the user specifying how many lines to skip, or by code that can calculate how many lines to skip.
At the moment, the code opens the file, calculates how many lines there are in the file, redims an array to this size, closes the file and then reopens it so its ready to have the data read.
This is how the data is input into the array at the moment:
ReDim data(lines, 3)
i = 0
While Not (EOF(1))
[Code]....
I was thinking a possibility would be to use a try statement so that if the data is a string, then it skips over that line, but i couldnt figure out how to put it together.

I am currently trying to write a program that will do the following. 1. The user will open a .txt file that needs to be converted into a CSV file. 2. The user will then click on a button to convert the file. 3. The program will parse the .txt file for the necessary data and will then write the data to a new CSV file. So far I am sure that I can write the code which will open the file and which will save the file to the new format. Where I am having problems is with the .txt file format that I have to work with. [Code]
Each field is fixed length with the empty space in front of the starting numbers being a field. I have been unable to find any code that would show me how to parse only certain data from this .txt file. What I need it to end up looking like is this: [Code] The program itself needs to be pretty simple as the .txt file will only have at most 25 to 30 records. I was thinking of using a StreamReader to read the data into an array, but I can't figure out how to get just the data I need out of each record.
