I have a dirty csv file that has 13 headers, but sometimes misses the last column value on some lines.
If the line has 12 columns, I would like to add ,0 as the 13th column.
Example:
2006/03/09,30403,7820,68,220,538,1956,14,3765,11384,26676,17932
2007/12/20,40796,13393,33,79,427,2604,11,4042,24974,44583,41561,7688
How can I read the file, and add ,0 to a line that only has 11 comma's and leave the lines alone when they have 12 comma's?
Ive figured out how to open a file to read and then display it, and i can probably work out how to write a string to a file. The part i am stumped by is this. Say i open a text file with the following text I has a badger i then want to correct this to I have a badger.
Its just an example and not for a grammar corection program. What i want to do is detect what was said and alter it acordingly. I presume this would come under string manipulation but i cant find any details on this.

View 4 RepliesQuestion: In one of my database, there is a value in a varchar-field: Brokers México, Intermediario de Aseguro,S.A. Now I make a new column as nvarchar, and want to take over the old values, properly encoded. Now two questions:
A) In C#/VB.NET, how can I change México back to the proper value ("México"), before storing it in the unicode field (assuming I know the proper source-codepage)?
B) Is there a way to figure out the codepage, if I don't want to do it manually ? (well, asking is free, but I suppose there is none).
I am manipulating xml with lots of date of birth. XMLs are already loaded onto datatable. The format we need is "dd/MM/yyyy" The dates are messy such as "dd-MM-yyyy" or "dd.MM.yyyy" so I am thinking to write a function that will auto correct on a set of predefined separators to a correct format. so I am thinking to do something like this but of course, this won't just work.i cannot use replace to replace an array. If i can just do that, everything would be fine. Hope someone can point out a way around. [code]

I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?

I am trying to create a program in VB.net to help me fix broken computer systems by parsing log files. I have some ideas but I have only built simple programs previously. I have ideas how to do this but so far my attempts haven't gone so well.Specifically I can either import a txt type file or copy and paste the contents of a txt file into the program and then have it compare what has been posted to a good/bad list then it reprints out what is bad in color coding. Also if their is a way to update the file it uses for comparison by entering in a txt file that would be stellar.

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.

In VB.Net we do not have a provision to parse a UTF-16 file But There is a provision for reading UTF-8 encoded file.The method is OpenText(). I want a similar method but it should parse or read a UTF-16 encoded file.

I'm wanting to have the option in my app to save configuration settings and then be able to import them on another machine or when the application is launched later. So I've got my saving routine working fine, using the XmlWriter class to write various settings to the XML file. I'm not quite sure what I should be using to do the parsing of the XML file to read the settings back in though, as there seems to be a few different ways to do this.Should I be creating an XmlDocument instance from the XML file and then using the ReadNode method or one of the other similar methods? Or should I be using the XmlReader class and one of its methods?is the format of my XML file:
<?xml version="1.0" encoding="utf-8" ?>
<!-- MY_APP_NAME Saved Settings - Version 0.9.5.0 -->

Just a little problem; seemingly easy but doesn't seem quite so straightforward as it should be. I am pulling an XML file from a server using the web browser control and the using the DOM innertext property to assign the contents of that XML page to a variable.
I would like to be able to efficiently parse through this variable as if it were an XML file. I have posted the output below.I can work out how to load an XML file using the LoadXML method from a disc or URL but I would prefer to parse it from within the variable. I know this should be simple but I was wondering what the best class to use would be as the most efficient / easy way of parsing data.

I'm writing an application in VB.net 2010, using Visual Studio 2010 Pro on a Win 7 Computer. The test code works for me correctly. However when I ziped the project folder and sent it to a friend (who is using Visual Basic 2010 on an Win XP Computer), it did not work correctly.
While runing the program in debug, we found a section of that code reads an XML file to construct an object provides a different results on the two computers. I'm not sure why the same code would parse parts of same XML differently. Most of the XML parsed correctly on both computer, just a couple of sections provides the incorrect result on the XP Computer using VB 2010 Express.
Sample of XML that reads differently:
<players>
<min>2</min>
<max>2</max>

I have been working on a very advanced feature that will allow programmers to right object that spit out other objects. Code that writes code. However, I have run into a problem. I use a file type that specifies to the coding parser how to create the object that is going to write the objects. Example, the Programmer writes a "NTF" file which contains code switches and variables that the Computer will parse and create a "Template Object" that the programmer can include in his project and call to generate the code objects. I'll right a object that creates an ASPX page for each table in my database, and I'll then call that object against my database. It's pretty straight forward. This "NTF" file has special parser commands, and uses VB.NET to manipulate the output based on the variables that come into the object. The problem is I would like to have an editor just as advanced as Visual Studio to recognizes the custom parser commands and the VB.net code. At the very least, something that formats the "NTF" file and integrates into Visual Studio.url...
