Is there a way to handle quotes with a field in text tab delimited file example:"This program works "really" nicely and is helpful" my reading and understand thus far is that while the file is tab delimited fields can also begin and end with quotes. Therefore is a field contains a quote it gets interpreted as end of field.[code]
View 9 RepliesHere is my situation.
data = "" & data & ""
xlsheet.Range(crange).Value = data
xlfile.SaveAs(FileName:=finalfilename, FileFormat:=6)
This code puts " around the data, puts the data in the range and saves the workbook(xlfile) with one worksheet(xlsheet) as a csv file.
If I open the csv file in notepad I find these following
1.quotes are removed
2.leading 0 from numbers are removed
How to ensure that quotes are present while saving the file programatically?
My program reads a 3rd party .txt file using OleDb and reads the file into a datatable. It's overall working fine except a user will occasionally have a problem reading a file. At this point.
Line that gets hung up
Try
Dim comm1 As New OleDbCommand("SELECT * FROM " & safeFileName & " Where " & Status & " = '" & StatusClosed & "'", con)
Dim dasold As New OleDbDataAdapter(comm1)
dasold.Fill(dtsold)
AddColsold()
[Code] .....
It can not retrieve a date for one of the fields, then gives error and does not get dates for each records after the one it gets hung up on but the date is in the file. If I open the file in excel and play with the column sizing, for instance just autoformat column width then it read the date and will work fine. I have looked at the file in notepad and cant see anything wrong in particular on the record it gets hung up on. I have no control over the .txt file since it comes form a 3rd party.
I have this program that uses OLEDB connection to import excel file to data table then use it in other functions.Now I have this question: What are the possible limitations of OLEDB when it reads the Excel file. The File is on xls format, and I want to know if there is such limitations(for example: It has limitation in reading value on a cell).
View 6 RepliesWe're converting a Classic ASP site to an ASP.NET site. One function was to upload a 'template' of data in CSV format for importing into the database. There were several different record types in there (the first field always indentifies the type of data).The task was to get the CSV into a DataTable so it could be validated (new project is to have MUCH better validation rules)
The code seemed pretty straightforward - watered down (taking out comments, Try/Catch, etc) it is as follows:
Dim da As New System.Data.OleDb.OleDbDataAdapter
Dim cn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDirectory & ";" & "Extended Properties=""Text;HDR=No;FMT=Delimited;""")
[code]....
The DataTable (dtData) is populated, but only starting with the second line of the CSV file DESPITE the fact that "HDR=No" is in the connection string.

I'm using Visual Basic Express 2008 (VB.NEt). I've created a project which
connects to a Microsoft Access Database (OLEDB) & displays the records using textboxes in the windows app.
I need to add a button which exports the database to a fixed length text file. Does anyone know the code I would use to do this?
This should create a desktop shortcut but instead it spits out an error that is because of the quotes inside quotes. They need to be there, I know this is the problem as I have tried without them and it has worked. Another problem though is that it creates the shortcut (when Idon'thave quotes in quotes) but wraps the whole TargetPath in quotes making the shortcut unusable. Here is my code:
Dim input As String
Dim s As String = Environment.GetEnvironmentVariable("UserProfile")
input = TextBox1.Text

Is there any way to use selectnode with the attribute having both single and double quotes? If we are having single quote in the attribute we can use like below,
nodeList = root.SelectNodes("//book[contains(title,""'attribute'"")]")
If we are having double quotes we can use,
nodeList = root.SelectNodes("//book[contains(title,'"""attribute"""')]")
how can I use an attribute ['attribute"] having both single and quotes in SelectNodes.
This problem makes it so that when I view the data, any fields with text are blank - only integer values show.
Code:
Dim PathToCsvFiles As String = "\\umpqua\companies\shared\MLImports\"
Dim FileName As String = "Strategy.csv"

I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
I'm trying to read a text file that contains info like this:
ACX-101-011 , J2168
BTXR-130A-013, D6733
AJ4-233-614, T8211
I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.
Dim TempFile As String
TempFile = "temp.txt"
Dim sw As StreamWriter

I have two text files with various columns, each column is separated by a tab (" "). What I'm trying to do is the following:-If the values in text file 2 column 1 does not contain any value in text file 1 column 1 then add that field to text file 2 and add a 1 to the second column, like so
String 1 If the value in text file 2 column 1 already appears in text file 1 columns 1 then just add +1 to the value, so if the above value is already in Text File 1 Column 1 and Text File 2 Column 1 then it would appear as.
String 2 And if it was to happen again then
String 3 and so on.I have the following coding so far.
Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1"))
Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2"))
IO.File.WriteAllLines("File2", lines1.ToArray) & +1)

I use the above coding, but it removes the second column?
I have been trying to figure out how to take text i have in a SQL text field and create the correct document from it. Here is the info i have in SQL: MIMEType is a string field that contains one of the following "application/pdf", "application/msword", "application/vnd.ms-excel" or a few others. DocumentBody is a text field that looks like "0M8R4KGxGuEPgADAP7/CQA" this continues for quite a bit. FileName is a string field that contains the original file name such as "test.doc" or "test.pdf"
I have tried using the System.IO.FileStream and System.IO.StreamWriter but in the document it actually writes the text that is desplayed in DocumentBody. I assume I am missing some way to decode this using the MIMEType but i just can not seem to find it.
I have some coding which displays a label if the value of a textbox matches any of the first values of each line in a textfile.[code]....

I am trying to import a TAB (NOt comma) delimited text file into a DataGridView. The following code works fine if I have a comma separated file. All I have to do is change the FMT to "Delimited".It just does not work with FMT=TabDelimited. All columns are read into single datatable column.

I'm a little new to VB, and I'm in a class for it, but I'm trying to do something we aren't going to learn in the class (mostly out of sheer interest) and I need help. I'm trying to read lines from a text file into a listbox, each line representing a new item on the listbox. For example, if the text file reads: [code]I want to be able to take that as is and read it into a listbox, where those words would appear in the exact same fashion; as a list, each as separate items. I've looked at the Help stuff and learned (sorta) about delimiters... but the thing is I don't want to write my entire list in a continuous line separated by commas--I want it to keep reading each line, and moving on to the next, until there are no more lines left. I am thoroughly stumped, and would appreciate it SO much if someone could help. For a frame of reference, this is the point I'm at now with my code: [code]Note that when I run the program, all it will do is read the first line of text available and stop; once I press ENTER in a text file, it decides to stop reading.
