VS 2010 : Set The Last Position Of String When Writing To Text File?

Sep 16, 2011

I'm outputting a number of variables to a text file and each field needs to be in a specific place.For example:I have a string that is varying in length, but will never be more than 5 characters. The string has to end on the 8th character of the line. Is there a way to write the string to ensure that the string ends at a specific place on the line, regardless of the length?

Send XML File Error 'Data At The Root Level Is Invalid. Line 1, Position 39'

I am attempting to send my XML file through an API. I have done this no problem by using the below code, however when I try and send the FILE over it will not work, I am now getting in the browser:

Data at the root level is invalid. Line 1, position 39.

Without trying to send FILE it works:

Xml_to_Send = "<?xml version=""1.0"" encoding=""utf-8"" ?>"
Xml_to_Send = Xml_to_Send & "<xmldata>"

Reading Text File Line By Line, With Resetting Position To Beginning Of File

Jun 23, 2011

I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.

I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.

I've seen other examples, where it works, but you must open it a different way -- with a file number.

Imports System.IO
Dim I as Integer
Dim LineText as String

VBSQL.OCX Is Failing While Loading Flat File Data (text File Data)?

Oct 15, 2009

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 was just playing around with trying to set up a datacontract that returned a class that had a property that took/returned an enum value. I could set the class up so that it worked great, but the service contract seen by the client had the enum turned into a string, of all things. Had it been turned into an Integer, that would have been useable, but not a string

Comma Separated Data File, Saved As A Text File?

May 30, 2011

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.

File I/O And Registry :: VB 2010 Formatting Data In Text File?

May 4, 2012

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

File I/O And Registry :: Export Data To Text File?

Mar 17, 2009

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)
