Putting Up Conditionals For Splitting A Text File?
Apr 27, 2009
I 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.
I'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
Basically i have a 500 line javascript file i made that runs in grease monkey (a add on for firefox ) I'm using vb.net to "compile" this script depending on certain check boxes.
So for example. (this is part of my script)
#RegionCapsEnforcer var array=document.evaluate("//*[contains(@class, 'postbody')]", document, null, 6, null);
[Code]....
and so on. So if chkCapsEnforcer was not checked it would skip that part and go to chkRevealUrl and if that was checked would get that bit. Then once it has gone through all the checkboxes it would write the enabled bits to a text file.
I 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.

I 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
Im trying to read a text file line by line and place each line in a separate Combobox. right now with my code i can only get it to print lines in separate message boxes.
The text file (test2.txt) contains 1, 2, 3,
[Code].....
if i replace the MsgBox code with Combobox1.text = (strArr(count)) i get nothing.
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.
I have managed to access and read a specific file line by line. If I wanted to split information by a comma or space and then sort alphabetically or numerically, how would I go about this procedure? Would I create a loop within the reading loop to parse the information?
Dim file As String = "C:Users est.txt" Dim Line As String If System.IO.File.Exists(file) = True Then
I'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.
I have a Text file that looks something like this:
"157548","asdf","ASDF","F","243","2/19/1993","(H)------","","Teams:","Emergency Contacts: (Uncle)-----(H)9----- (W)----- (C)------,"ENG2D1-05","460977" So where
"," is, How would I end up splitting them?I tried something like this:
vb Public Sub ImportList() With frmOverview If .ofdImport.ShowDialog = DialogResult.OK Then
[code]....
But it only ended up splitting the CourseCode ("157548")
so i have been working on a small little project for chemistry class that the user enters in Chemical formulas and when a button is clicked it provides the atomic mass of the formula in a label, and the MOLE value for that chemical equation.
I am running a program in windows forms visual basic and im trying to make multiple counters
Here is my code:
If txtAnswer.Text = nMathSum Then nCount = nCount + 1 lblCorrect.Text = nCount
[code]....
It suppose to count how many times i answered correctly and incorrectly The Counter for the Sum is working fine but the counter for the difference has a problem. When i input the correct answer it goes to the incorrect label.
Im writing a program where im trying to split some text imported from a textfile into a textbox into an array.The array is undefined and i would like each piece of text to be an element in the array. I would then like to sort this information into alphabetical order.This is the code I have at present; I apologise if any appears to be out of sequence or whatever, VB is a rather puzzling language to myself!
PS i have the code behind a button as you can tell from the code.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim textInput As String textInput = TextBox1.Text
Is there any easy method for splitting text in VB.NET? (using a start and end string to grab whats in between?)I do this all the time in JScript with the following:
I am trying to do something, which I seems to be pretty simple, but no matter how I try, one thing or another doesn't seem to work. All I want to do is check if the current date is 14 days prior to an expiration date display how many days until the expiration date, but if the current date is past the expiration date, display an expiration notice.
If have tried a bunch of different ways, but none seem to work. Here is the latest variation that is not working:[code...]
Problem with splitting, i was able (with help) to get a text from html tagname, the thing was that there are different text with the same tagname and the only way i can to receive each one was with this:
CODE:
With that i get this text:
CODE:
So i want to remove the </a , how can i do it?
So now i have in textbox2 the text but have a lot of unnecessary html so i used 2 split more
CODE:
That work perfect but just for one and i need the others, how can i "integrate" that 2 split function more for get a clean text for each one. If in the first code i use this
CODE:
All texts are in a new line but then the second code doesnt work :/
I'm reading a tutorial provided by someone at my university, and it claims that if you're debugging a VB.NET program, you can hover over a conditional (e.g. "Age > 13") and it will be evaluated. However, in VB 2010 Express, I am not seeing this functionality.
I believe the tutorial may have been written for a previous version of VB.NET, so I was wondering if anyone could tell me if this used to work and has been removed, or whether it has never existed?!
I am able to hover over a variable and see it's current value, and I can even "Watch" an expression (such as the conditional), but the tutorial claims[code]...
I have created a DEMO project to illustrated what I am referring to. I have a simple form, the button is set to Enabled False in the property inspector. When the user complete the form controls(fields) the button is Enabled. Everything seem to be working except the following: When the user completes all the field, they must type twice in the MaskedTextBox for the button to be Enabled.
Even though there is no actual characters typed in the box because of it's restrictions, why do I need to type twice in the MaskedTextBox before the button is Enabled. Here is my code: Public Class frmActivateBtn Dim blnCheckName As Boolean, blnCheckPet As Boolean, blnCheckColor As Boolean, blnPhoneCheck As Boolean Function turnTestButtonOn() If blnCheckName = True And blnCheckPet = True And blnCheckColor = True And blnPhoneCheck = True [Code] .....
So I'm trying to import a function from a library I'm developing. I have "libraryD.dll" built for debugging and "library.dll" for release. Unfortunately, that means that I have to do this:
[Code]...
Now this would be fine but for ALL 40 functions this would make things very ugly to look at (and a tad bit unfriendly).I would like to do something more like this:
I have a file that has > 10 rows. I want to create 9 files that each contains equal number or rows, with the 10th file containing that equal number plus any left over.[code]...
How can I take oDataList and parse it into 10 files without having to loop through each file and oDataList to write line by line?
