Read Text File With Tab And Carriage Return Format To Store Them In Array
Jul 1, 2009
I have to text file in the following format :
Word[tab][tab]Word[Carriage Return]
Word[tab][tab]Word[Carriage Return]
Word[tab][tab]Word[Carriage Return]
I want to get all the words before the tab into one array or to create a new text file and the all the words after the tab into another array or create a new text file too.
Here my function to get the words before tab into an array :
Protected Sub MakeWordListBeforeTab()
Dim filename As String = "D:lao�0001.txt"
'read from file'
[Code].....
I wrote the above function to get all words before tab but I got all the words into array. I've been trying to use the Split method above. What is another method to split those words ?
I know this can be done with regular expression but I don't know regex yet. If you can show me how to get this done with regex it'll be awesome.

VBA 2008, Powerpoint office 2007. .NET.when i typed in a RichTextBox or Textbox. (sorry if it matters which text box i am using) maybe
" Hello, I am Russell!
i love you very much
that is all!"
maybe like this. and send this over to another device.when i received the message , i got " Hello, I am Russell!i love you very muchthat is all!"It did not read my CR or Enter. how do i implement this so that if there is any CR i can detect where it is and put it in accordingly?

I have a textbox, and it's set to multiline, so a user can enter a few sentences. The problem is, if the user hits the enter button while in the textbox, it's starting a new line. This data is being saved as a text file, and it's causing problems when the text file is loaded back into the app, causing load failures.
I'd like to completely make the enter key useless when the textbox has focus. Or, if they hit enter, it tabs over to another button.
Here is some code I used to make the enter button behave more like a tab-
Private Sub txtCallNotes_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs)
If e.KeyCode = Keys.Enter Then
Me.btnSubmit.Focus()
End If
End Sub
The problem is, the enter button still does a carriage return, causing a new line.
In the properties, Accept Return is False.

I'm using VB.Net and I am creating a mobile application. I have a checkbox that the text needs to be on more than one line. I've tried everything including setting the text property on the load screen function and using the vbCrLf and I just see the Line feed square but not multiple lines. I've also tried resizing the box and that didn't work either. how to make the text span multiple lines?

Using vb.net/asp.net 2005
I am trying to create a string message for an email that I am sending out from my asp.net page like so:
For Each dr In dtDataTable.Rows
strMessage = strMessage & vbCrLf & vbCrLf & Environment.NewLine & dr.Item("UserName") & Environment.NewLine
Next
so I am looping through a datatable and getting each name from each row, that is working well but when I get the email it appears in my inbox with all the names mashed together, you see I am trying both vbcrlf and newline but looks like neither is working

I have developed a vb.net dll (.net 3.5) which does the following :
- I have data of several stock market companies.
- They are stored in several folders under a main folder.
- These files are random access files.
- There can be around 4000 files in total for example.
I wrote a program which reads a current csv file and stores contents in array. Then I store name and path of companies in folders (which I was talking about). Then I match one company from csv (stored in array) to companies in user's folder (again reading from array). If found I insert data in the file (random access file). This whole process takes for eg. 2 min my system. A similar program was written years ago by someone in powerbasic which takes slight less time if run one but if run for multiple csv files it takes only a few seconds doing the same thing for other files. When I do the same thing (by writing code to .net dll) and making a dummy app to run it, no matter how many times I run it takes same time. And is way slower than the earlier one (PB) one I was talking about. But if I paste the same code in my win (.net) app and not use .net dll then it runs a bit faster.
I need to show status so if I pass my form's label reference to .net dll and it updates it does that slow down process a lot. As I mentioned I am trying to process the files and it takes longer in .net. What should I do to get best performance? Unfortunately due to unexplainable reasons I cannot change the format or use a db. The files which I am reading/writing (random access files) are use by other products so I have to stick to that format. What I am doing is storing the location of those files in array so that I don't have to search folder again. that is not taking time. But opening reading and writing files is time consuming if I am doing it for few thousand of them. A similar program in powerbasic (developed years ago) runs fast. Running code thru .net dll is slower than running it thru program. Why?

My text file is a settings file and I know I will be adding more to it in the future, right now it reads "autoplay=false;mintray=false;"I am currently using probably the most inefficient way to check both of those settings:
if contents = "autoplay=false;mintray=false;" then
elseif contents = "autoplay=false;mintray=true;" then
elseif contents = "autoplay=true;mintray=false;" true
elseif contents = "autoplay=true;mintray=true;"
endif
How can I read the file, find each word from the equals sign to the semicolon, and store each of them in a variable identified by the text before the equals sign? Something like this:
contents = "autoplay=false;mintray=false;"
autoplay = "false"
mintray = "false"
Also, how can I edit the settings in the text file without having to overwrite everything every time I save to it? For instance; finding mintray in the text file, and changing mintray to true instead of overwriting the file with "autoplay=false;mintray=true;".
This is my current
Reading
Dim fs As New FileStream("C:myfile.txt", FileMode.Open, FileAccess.Read)
Dim d As New StreamReader(fs)

I am pasting data from an Excel spreadsheet and and adding a 0 to the start of each 9 digit string it's it's missing. This works great if I'm pasting from notepad but from excel I see from this line of code
RTBUserID.Text = RTBUserID.Text.Substring(1, RTBUserID.TextLength - 1)
that there seems to be a carriage return (denoted by a square)
System.Windows.Forms.RichTextBox, Text: 62818972" & vbLf & "62819154" & vbLf & "62999101" & vbLf & "62985054" & vbLf & "...}
Question is, how to I remove it.I have tried the following code but to no avail..
For x As Integer = 0 To RTBUserID.Text.Length - 1
RTBUserID.SelectionStart = x
RTBUserID.SelectionLength = 1

[code]The code within the Private Sub replace the spaces within txtCallnumber.Text with carriage return line feed and does what I need it to, but when I place the code into the Private Sub that is above it places the carriage return line feed into the cells in the datagridview: column(CALL NUMBER). The txtCallnumber.Text is bound to the DataGridView column(CALLNUMBER). I do not want the DataGridView column(CALLNUMBER) to have the carriage return line feed

I am generating report in word(i.e) I am exporting all the data from the database and replacing it in with the placeholder in the word document. While the data is being retrieved from the database if the data contains any enter or new line character it retrieves it with the boxes and hence it replaces the string in the word with boxes such as for eg. abc and then box icon and then xyz on other line for abc...xyz text.how can i eliminate the box icon and still display the data as above? I have tried replacing the character using chr(11), chr(13), system.newline etc but the box icon still exists? Is there any other way i can perform the above task?

I am using a multililne textbox and I want to take the text typed and merge it with another string. So for example....
CoverPage = Replace(CoverPage,
Me.Note.Replace("{", "{").Replace("}", "}"), txtNote.Text)
Where Me.Note is a string that I am looking for and replacing it with the contents of txtNote.text. And then storing it all back in the string CoverPage.CoverPage is an rtf string that will holds place holders for the text I want to change.(That works) But when i update the note that may have a carriage return in it, the coverpage does not reconize the carriage returns comping from the Multiline textbox when its displayed.I have tried replaceing Enivronment.Newline with vbCr, vbCrl and whatever else I can think of. is there an issue with taking a string carriage control and tranfering it to a rtf carriage control?
