.net - Microsoft.VisualBasic.FileIO.TextFieldParser Changes Ascii 241 To ? Ascii 63?

Dec 11, 2010

I am using Microsoft.VisualBasic.Fileio.TextFieldParser to parse a CSV file that was created with Excel 2003. The parser is working great with the exception that it is converting extended ascii values to question marks! So if the file content was:

The TextFieldParser is returning
? 3

I have tried all of the encodings in the System.Text.Encoding package with no luck. I thought I had it with UTF7 but it was dropping other characters like replacing the + sign with a space.

Microsoft.VisualBasic.FileIO.FileSystem Equivalence In C#?

Apr 6, 2011

I use VS 2008, .net 3.5, C# projects. I need do the same functionally like Microsoft.VisualBasic.FileIO.File System.DeleteDirectory. Anyone says referencing the Microsoft.VisualBasic is often undesirable from within C#. Any association with VB from within C# code strikes me as undesirable. Using FileSystem class, this is a perfectly fine solution, but I prefer not references Microsoft.VisualBasic library. That one I would avoid.

VS 2008 - Read The Unicode Text From A Binary File

Jun 3, 2011

I ran across my first unicode data, and I am not sure what to do with it. I read the unicode text from a binary file using the ReadBytes method, because ReadChars threw an exception when it tried it. Well, long story short, I have found a way to work with the data, I can convert it using a small Function I wrote, which goes something like this: [Code] And this works wonderfully. It just throws away anything not in the ASCII range, including the BOM at the start of the unicode data.

But I would guess that this method is not very universal and probably not the best way. Are there any VB functions available to do this sort of thing? I was able to find something called Text.Encoding, but there didn't seem to be a reverse of that not that I found anyhow. Any ideas?

How Best To Parse A Text Log File

Jun 22, 2010

I occasionally have to search a very large text file as a troubleshooting step. The file is continuous text (with spaces between much of the text) but almost everything is date/time stamped. The text is actually messages between two machines so I'd like to insert a line break after every message so that I can follow the protocol exchange. Thre are also a few key words that I'd like to again, separate with a line break.

Parse A Text (log) File?

Jun 2, 2009

I am using VB.NET 2005 (if that matters).I need to parse a text (log) file in which to process lines like:

Program Up at: Tue Jun 24 11:32:53.656 2008 - TerrificProgram.exe
<some lines here which I ignore>
0.00:24:16 - Emergency Stop!
<more lines to ignore>
Program Down at: Thu May 29 22:22:56.000 2008

where the 0.0:24:16 is the offset in TimeSpan format (d.hh:mm:ss) relative to the 'Program Up at" datetime.The 'Program Up at: <date/time>' line I successfully detect (in another function which works) and as a result a set a Boolean flag that I am in a valid <Up> - <Down> sequence and I also set a Start-up DateTime var to which to add the offsets later.

The task is to convert the TimeSpan at the beginning of the 'Emergency stop' line to a regular DateTime expression and to write the converted line to another log-file.Simple, isn't it?The function I use for the above purpose is:

Private Function IsTimeSpan(ByRef InputLine As String, ByVal ProgStart As Boolean, ByVal DTofProgStart As DateTime, ByRef NewDateTime As DateTime)
Dim iLine As String = InputLine
Dim Index As Integer = iLine.IndexOf(" ")


What I am doing is I pass each line ('InputLine' parameter) from the original log-file to the function together with the 'in <up>-<down>' flag ('ProgStart' parameter'), the start ot program DateTime (in the 'DTofProgStart') and I want the NewDate to hold the real datetime of Emergency event occurence (not its offset).

What happens is that I successfully detect the lines of interest but the NewDateTime is not updated (though 'ts' is in the correct format and the assignment 'NewDateTime = DTofProgStart' correctly assigns the passed value).Another curious thing is that the line

InputLine.Replace(testStr, NewDateTime.ToString("MMM dd HH':'mm':'ss yyyy"))

does not change the original TimeSpan beginning of 'InputLine' with the regular DateTime (though not updated) in 'NewDateTime'.Why?

So I'm guessing it has something to do with the fact that I don't have office loaded on my computer. Now I have another laptop, with office that I loaded this project on, and it works fine. So do I have to load office on this computer, or can I just reference something?

Parse A Text File By Line?

Jan 20, 2011

I'm running into a problem whenever I try to parse a text file by each line. I know I could use stream reader to read line by line but it is a lot easier to simply use split() and I would also like to know the reason why split() doesn't work.

For example, I created a file "test.txt" and filled it with the following text.


then put the following code in the load event of the form (a button click would work the same).

Parse Delimiter Text File?

Apr 12, 2012

I'm trying to use VB.NET to parse a very large plain text file (2 GB). It is a database and has a field delimiter of SOH and a record delimiter of STX. I want to separate the fields and records of the file.

I would normally read each line of a text file and then use the split function to separate out the fields. I can't use this approach as there isn't always a delimiter on every line.

Is there any way to read a file until STX is found (rather than one line at a time)?

VB 2010 - Text Reader Encoding And TextFieldParser

Apr 1, 2011

I have a VB2010 project where I need to read a tab delimited 50MB file using Microsoft.VisualBasic.FileIO.TextFieldParser. This technique works fine until the reader encounters a Unicode character upon which it inserts the little square thingy. The obvious choice is to change the encoding of the reader to Unicode from the default. This would probably work fine but for most files but this one is fairly large and I get the error TextFieldParser is unable to complete the read operation because maximum buffer size has been exceeded. By the way this file can be read completely without the Unicode option. Making the file smaller or breaking it up really isn't an option. Is is possible to increase the buffer size or is there another way to read this data that places the data in fields like the textparser and allows unicode characters?

File Io - Textfieldparser Delimiters .net

May 14, 2012

I'm currently busy coding a hangman game in VB.NET.As a wordlist, I have a textfile containing 1520 words, each one seperated by a new line. The best I could think of to get a random word is with a Randomize() function. Then getting the word from the line # which was randomly generated.


Is there any better way for me to extract the word from that random line? If not, what would be the delimiter I should use for this and how do I quickly change the breaklines into that new delimiter without resorting to Office?

Also, how can I use the textfieldparser to get the file from resources? When I tried using my.resources.filename instead of "filepath", it gave me an ArgumentException due to "invalid characters in the path".
