VS 2010 Splitting And Trimming Text File?
Apr 15, 2009I have a large tab delimited text file to process each day (usually around 25 mb) consisting of usually well over 100,000 lines. The file is actually made up of about 9 or 10 reports separated by "END OF REPORT". I'm wanting to write each individual report to it's own text file. Some values may have trailing spaces or even contain nothing but spaces, so I am wanting to trim those to only the data, or be left with null. Ultimately each report will be imported into sql server tables. The code I have below runs successfully to completionwithout error although each text file is empty. The script is also extremely slow and seems to use quite a bit of memory. The arguments are ad
View 1 RepliesSplitting Delimited Text File?
Jul 20, 2011I've got a problem reading in a Tab-Delimited text file. There's an extra tab in one of the fields its reading it thats not a delimiter, and it's throwing off me reading the file into a table. This specific file does have quotations around that field though.
What would be the best way to take that tab out before splitting the row by vbTab?
Im reading each line in the text field like this, splitting on vbTab. X is a string array
text = x(J).Split(vbTab)
Putting Up Conditionals For Splitting A Text File?
Apr 27, 2009I have I text tab delimited file. in every line of that file at the same position in every row of the file I will have a bit that I would want to compare against 23 values (I will call them criteria). So if on every row the string I need matches one of tjhese values then that row will be written in File1.Txt if that value doesn`t match any of the criteria the whole row will be sent to File2.txt.
So far managed to get the original file written in the same format in a newly created file.
how to get the functionality I described working but am stuck with correct syntax.
Here is what I have so far:
Dim fs As New FileStream("C:Original.txt", FileMode.Open, FileAccess.Read)
RichTextBox1.Text = ""
Dim d As New StreamReader(fs)
[Code]....
Now I will need to declare every single row in RichTextBox1 as String then will have to get the bit I need will have to declare that as well(I will need from every row the string taht is between characters 96 and 104), also where do I keep the 23 criteraia values.
Splitting Data Read From A Text File?
Jan 10, 2012I am exporting a directory list from a FTP directory to a text file, I would like any suggestions how best to read and split the information detailed on each row in the text file as information isn't Tab Delimited (which i have code for if it was) and the number of spaces between each attribute is different. Below is a snippet of the text file, the main two I require is the File Size and the Filename.

Splitting Delimited Text File Into Array And Variables
Nov 16, 2009I have a delimited text file, let's call it models.txt and it's delimited by a comma with carriage returns.
example:
21,Z920081
22,Z920082
59,Z930023
120,Z930027
I'm trying to input this into an array and then a combo box using:
dim item as integer
dim array() as string
dim ifile as integer
[CODE]............
What I want to do is to display the right part of the delimited text (Z920081, Z920082, etc) in the combo box. But when you select the item in the combo box, I want it to use the left part of the delimited text (21, 22, 59, 120, etc) as a variable for other use.

File I/O And Registry :: Reading Text And Splitting To Arrays Then Echoing To Textboxes
Mar 1, 2010I'm currently making a program that will be used to practice German. It reads from textfiles that have English words (noted by # prefix) and German words (noted by $ prefix). An example of this:
#hello $hallo
#good $gut
#evening $abends
The way it currently works is it loads a text file, finds all # and splits to an array called "English" and finds all $ and splits it to an array called "German" What I want it to now do is feed the "English" entries into textboxes on the left, and "German" onto textboxes on the right so I can then match them out and make a sort of memory game out of it. Unfortunately, I don't know how I would loop an array through multiple textboxes. Conveniently, the textboxes on the left have even numbers, and the ones on the right have odd. Is there a way to possibly find all evenly numbered textboxes and loop "English" array entries into them, and the same for "German"? I've realised this has now gotten a little convoluted, but hopefully somebody understands. I can screenshot the form for better explanation, and copy my existing source code if anybody wants it.

Splitting A Text File That Has ","?

View 19 RepliesSplitting A CSV File Line Array Using Regex
Jan 5, 2011I used to do a bit of coding in early versions of VB years ago but moved on to things like RPG400, CL and SQL on an AS/400 box. As I am no longer in this career, I havent touched an AS/400 for a while either.
I am currently working on a visual basic console application in Visual Studio 2005 which takes various csv files from an osCommerce web shop, processes them and writes the data to TAS Books accounts software with the aid of the Infoplex COM module.
I have 2 functions, one reads each line of a csv file into an array, and the second function uses Regex to split the lines array into the various fields before they are added to a structure.
There are something like 5000 records (lines) in the csv file, one example is as follows;
[Code]...
My problem is that due to the formatting of the product description in the example csv line above, it fails the Regex match and therefore fails to read.
I know this is because my pattern is wrong, but I'm not sure how to solve it, I think all I really need is for Regex to split the line by the "," between each element, this might be a little difficult because some of the descriptions contain both , and " but never one after the other.

Trimming A String At Both Ends?
Jun 12, 2011I'm reading in an xml file, which is working fine with no problems, but I want to re-format one of the elements data attributes slightly.
The XML attribute output is currently Wind: NW at 6 mph
What I want to do is extract just the number from the string, I figured an easy way would be to simply play with the length of the string and assign it to another variable.
However, I've ran into a little problem.
I can use windRtrim = wind.Substring(0, wind.Length - 4) (Where windRtrim is the amended string variable and wind is the string from above)
This returns Wind: NW at 6
Which is great, but the problem now is trimming the correct number of characters from the beginning of the string as it'll be different if the number were to go over 9 (ie. 10 and above)
Trimming Spaces From Strings?
Sep 14, 2009I've made a little map-maker for my tile game, which just stores a single digit for each tile. The problem I've noticed, is that when I save a digit, it tags a space on the end of it, so that when I read the file I have to read every 2nd character.... plus ofc it makes the file twice as large. Is there a way to trim the space from my digit when I save it to a text file?
