I'm using the following code to read some values in from a tab delimited text file:
vb.net
Using Parser As FileIO.TextFieldParser = My.Computer.FileSystem.OpenTextFieldParser(LogFile, vbTab)
Parser.TextFieldType = FileIO.FieldType.Delimited
Dim comments(0) As String
[Code]...
As you can see I have set the HasFieldsEnclosedInQuotes property to true on the textfieldparser because I want to make sure I capture the data correctly if quotation marks are used. If I set the HasFieldsEnclosedInQuotes property to False then it all works (or at least it doesnt error anyway) but like I said, I need to have that set to true because otherwise if the line contained a tab character within the quote marks then my app would think this was two separate fields and process it incorrectly.
I need to check if the webpage contains class="listingTitle">
So im using this
If (WebBrowser1.DocumentText.IndexOf("class=""listingTitle"">", StringComparison.InvariantCultureIgnoreCase) > -1) Then That doesnt work. I tried "class='listingTitle'>", and I tried "class=""listingTitle"">" both dont work.
If have this code which writes the following into a text file. sWriter.WriteLine("a" & " " & A.Text)This is the resulta 45-Id like the text in A.text to be in speech marks, so the final result is something like hisa "45"But I cant seem to quote quoatation marks, it gets all confused.
This is a very beginner question, but driving me crazy. Why isn't this code working?[code]Have also tried using Response.Write() but that doesn't work either.
I have a Powershell script and no matter what I try it completly ignores any quotation marks in the script. The error occurs when I run the script from my VB.NET code yet, I have been running scripts sucessfully through VB.NET for a while now. For example, my script starts with finding out the server name...
I have a button and a textbox, the button is linked to an OpenFileDialog and the name of the file is in the textbox. OpenFileDialog1.ShowDialog() Dim filename As String = OpenFileDialog1.FileName Textbox1.Text = filename How can I make it that the file name is always showed between "" because dos doesn't understand spaces in folders.
Trying to split a line wherever "," appears (with the quotation marks), The problem is VB.NET uses " to start/end strings, so I tried using .Split(""",""") but that then splits it by " not ","
Is there an Excel text file format (XlFileFormat) to export that will not put quotation marks around strings? I've tried xlTextWindows. Maybe there is an additional setting I'm missing? Most of the time, the datasets I'm exporting are in CSV, but I have a situation where I still want to export with an Excel type (long story) but really it is just a small blob of text. Otherwise, I'd just export to a text file; trying to avoid that for this one case.
[Edit]In this case, I have an Excel workbook with a single worksheet, with one cell (No header) with the text: [Reports]
Below is the code I have been working on in VB.NET What basically happens is that when the user presses the calculate pay button, a message box is supposed to appear with all of the information in it, however the error comes up with: 'InvalidCastException: Conversion from string "Total pay: 5" to type 'Integer' is not valid.'
Public Class Form1 Dim TotalPayWithoutOvertime As Integer Dim HoursWorked As Integer Dim DoubleRate As Integer
I've been going through a VB book I had while in College, and was trying to figure out different ways of making programs work.One assignment was to create a multi-dimensional array to figure out wind chill factors. The only part I really can't get to work right is using 2 numericUpDown controls. Using 2 dropdown menus was obviously easy because the items are indexed, but as far as I know, numericUpDown controls are not indexed.
Instead I used 2 selectCase statements to determine the index in each updown control, then passed the indexes to a function to determine the answer.The numericUpDown controls both increment by 5, (wind from 5 to 30) (temp from -20 to 15)Just looking to see if someone has any ideas of a better way of doing this.
I have an ActiveX exe that works on word document. I want to make the ActiveX exe to work inside internet explorer. For Ex: if there is a link in a web page pointing to word document, clicking that link should open the word document in my application but inside the internet explorer itself. What i am able achieve till now is i am able to open the word document in my application but in my application window using MIME.
Is there a way to make ProgressBarRenderer.DrawHorizontalChunks actually work the same as the standard ProgressBar rendering?
If you create a Class that Inherits ProgressBar and override the OnPaint event then you have to render the Empty ProgressBar and it's fill% manually. This pretty easy with the ProgressBarRenderer. However, the DrawHorizontalChunks function is ugly compared to how a standard ProgressBar renders itself.
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs) ProgressBarRenderer.DrawHorizontalBar(e.Graphics, e.ClipRectangle) ProgressBarRenderer.DrawHorizontalChunks(e.Graphics, New Rectangle(0, 0,

I also have a second more minor issue in that I Shadowed the value property (for various reasons), so PerformStep (which then has to be Shadowed to keep the Value property in check) causes it to increase in blocks rather than smoothly growing between the two Values (old value growing to old value + step); the only solution I can see is to extend the code in the Shadows Sub PerformStep code to move the Value property gradually between the old and new values.
I'm making my Media Player in VB2008. I got Listbox1 as playlist. Buttons play and stop works, but buttons next and previous don't. What code i need to put for them?
I have a textbook loop using a TextFiledParser, which terminates when EndofData is trueTrouble is it's true prematurely. There is a knowledgebase article which decribes the issue perfectly but it only applies to V3.5. I'm using V4.0.I can't for the life of me see anything wrong with the data file, or the code. I reluctantly
It seems like in order to use "TextFieldParser " you need to include the path of the file to be parsed. Is it possible to use OpenFileDialog1 and then choose a file? I keep getting error messages.
Public Class Form1 Private Sub btnOpen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpen.Click
I am trying to use the TextFieldParser in windows 7. I have tried running visual studio 2008 in elevated security mode but i still get file not found. I have tried it on my XP machine and it runs completely fine.am i doing something wrong or is it that windows 7 doesn't like to give access to the filesystem?
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.
[Code]...
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".
I am having problems getting the data I need. I keep getting "index was outside bounds array" I guess I am just plain confused. The text file looks like:
First = John Smith Last = 550 Jackson St Street = Nantucket City = xxxxxxx Misc = xxxxxx
Ok so I am taking jm advice and using TextField Parser instead of ADO.net to read my delimited files and then build my own datatablesFirst question is how would I query the data?I need to be able to have two tables, one with sold propertys and one with propertys still for sale.The table I created thus far has all the records, the problem and my second question is how do you allow for a null value ?If one of the records isnt Sold then it won't have a Selling Price therefore when I set my datacolumn to be of System.Integer type It is not accepted

I am using the TextFieldParser to read a 3rd party .txt Tab Delimited File Sometimes the file contains duplicate column names and subsequently I cant create my DataTable.
How can I check for duplicates first and change the name of the duplicate fields so I can populate my Table?
Example:
I have two columns called ST and would like to Change of of them to ST1 or something similiar to populate my table
Dim safeFileName As String = IO.Path.GetFileName(Me.OpenFileDialog1.FileName) Using myReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(safeFileName) myReader.SetDelimiters(vbTab)
The following is a text file of 4 lines delimited with (,) making 8 elements and 1text string making 9 eliments in all.In my Environmental dictionary Environment and Conservation, Devoid of life non-biological.The Oxford University Physical and Theoretical Chemistry Laboratory definition says free of biological organisims. Does this mean the water in a pond is not abiotic but pure water is?"The following from the MSDN help that works:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Using MyReader As New Microsoft.VisualBasic.FileIO.TextFieldParser("L:GlossaryListBox0
Is this class normally slow or maybe there is something in my process making it slow.I have to import 170,000 rows of data from a fixed length text file into a SQL table. It takes about 2 minutes in a DTS package on SQL server 2000. But we are migrating to a SQL 2008 server and since this code has several manual steps and does not manipulate the data I thought it would be easier to use the TextFieldParser object to handle reading in the data.
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?
I use a textfieldparser to read a csv file in my app. I set the delimiter to a, Problem is, if there is a field that contains double quotes, the textfieldparser fails. So if I have Example",test. it fails. If i remove the " it works. That's quite odd. How can I fix this.
I am using VB.NET's TextFieldParser (Microsoft.VisualBasic.FileIO.TextFieldParser) to read a delimited file. However, when I try to read in a field with consecutive newlines within the field, the consecutive newlines are turned into a single new line. I would like the consecutive newlines to be preserved, but am unsure how.Here's an example file that I am reading in with exactly one field. The quotes are part of the file's content and there are three newlines (including the two consecutive newlines following line 2):
"This is line 1 This is line 2
This is line 4, which follows two consecutive newlines."Here is the code that I am using to parse and read in the file:
Dim reader as New Microsoft.VisualBasic.FileIO.TextFieldParser(myFile, System.Text.Encoding.Default) reader.TextFieldType = FileIO.FieldType.Delimited reader.SetDelimiters(",")
The end of the text document my application is reading is denoted by a character that I cant identify, copy or paste. I attached an image of it so you can see. I have no control over the formatting of the document so I can't change the character. During debugging it shows the same character as shown in the picture, but if I hit the little tack next to where the variable shows then it changes to "f". However, if I try to see if the variable equals "f" it returns false.
