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.

View 2 RepliesI 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(" ")
[code]....
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?
Example Data Link - Sorry, wouldnt format correctly when pasted.

I have to parse through a text file that is growing and currently is about 30MB, but it takes a long time for the stream reader to load it before It can loop through the lines. Is there a faster method other than the streamreader?
View 2 RepliesI'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.
text1
text2
text3
then put the following code in the load event of the form (a button click would work the same).

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)?

My application is supposed to parse a text file (relatively easy) and create an excel spreadsheet report. Should I write a stand alone VB.NET application that saves the excel file, or should I use VSTO? I am unsure if there are any differences in terms of ease of development, usability issues, API functions available, etc.Are there any other programming languages/interfaces/libraries that will allow me to rapidly develop an involved excel spreadsheet? I am talking about things like functions, graphs, etc.

I am trying to parse a very large text file for certain strings. The text file is part of a level-making software for an old game I play. The text file basically contains all the information the level designer software needs, but the only important bit is the 'texture information'. Basically what I'm trying to create is a little program that parses the text files and shows the user a list of every texture in that text file. The problem is, the strings denoting textures are not really easy to find, and I can't think of any sensible and fast way to get them...

The problem is that the response we are getting in code is incomplete when compared with what actually renders in the browser. The html we are getting shows a javascript function in the body of html where what we really want is the result of the function, which includes the data we need to capture. This is confirmed by loading the page in Google Chrome, clicking on the text "100360" and choosing "inspect element" which allows us to see the full page response with the data we need, specifically the following line:
<pre class="pre-longText-wrap">100360</pre>
How to get this "raw" page response? It may be that the script is taking a few seconds to respond and that we are only seeing the initial page response.
