VS 2005 : StreamWriter Position To Line Number 9?

Sep 28, 2009

I'm testing a small program that can read & write to an rtf file. Examples I have found work fine, although I have two questions:

1)If I need to ALWAYS write to line number 9 of an existing RTF file, do I need to "read" 9 times or can I immediately position myself to line number 9. I have found character manipulation but can't seem to find what I need with positioning to a particular line number.

2)BOLD text: I have found examples where I should be able to format my text, such as

MyFile.WriteLine ""
MyFile.WriteLine Text
MyFile.WriteLine "0"

but when doing this, it does not "bold" my text, but actually prints the text exactly as shown. I'm looking for information/links that I can "bold" "Italicize" text. Code is written in VS2005.

Forms :: Streamwriter Writes To A Specified Line#?

Sep 30, 2009

I am needing to write to a "rtf" file, and always insert my text on line 3 of either a new or an existing rtf document.I'm familiar with vb, but have not done much with the system.io functions. I have been testing several examples from the internet using the streamreader and streamwriter but still having issues finding a way to "insert text" on a specified line number. My questions:

1)I will always need to write on line #3, do I need to read all lines as this example shows "lines.AddRange(System.IO.File.ReadAllLines("C :/test/myrtffile.rtf"))"

Basically this is a function I call during the program booting and it creates the necessary directory and also the LOGIN.CYS file empty... then later data can be added.My issue is that it keeps adding a line to the .cys (which is a .txt file) but I just want VB to create a plain text file with no content inside...

VS 2008 Streamwriter Writing On First Line Only?

Jun 24, 2011

I am coming across a lot of odd and annoying problems in this program and have almost had enough lol.

I cannot figure this one out for the life of me. I have used streamwriter a hell of alot of times and never once experienced this. But basically I have a string array and I need to write the entire array to a text file with a new line for each array item. So I have gone ahead and done this:

[Code]...

However the outcome is the text file only contains 1 line and that line is the last item in the array yet I know the array has got at least 50 items in it.

Streamwriter And Strange Charactors - Opening The Streamwriter With Different Character Sets As The Third Parm?

Apr 21, 2010

I am taking in two html files and creating one out of them. To do this I am opening the first html file and not writing out the closing </body> and </html> tag and opening the second file and not writing out the corresponding opening tags, as well as the <style></style>section. I start a streamwriter, and write the lines out to it, and then close the streamwriter. My problem is that the output file is filled with strange characters. I've tried opening the streamwriter with different character sets as the third parm, but all this does is change the characters to different strange characters.It says charset=windows-1252 at the tops of the input files (and the output files for that matter - since I'm just reading stuff in and writing it out - with the exceptions mentioned above).Questions;First, do you think I am properly approaching appending two .htm files together?Second, how can I eliminate these strange characters.

Reading Text File Line By Line, With Resetting Position To Beginning Of File

Jun 23, 2011

I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.

I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.

I've seen other examples, where it works, but you must open it a different way -- with a file number.

Imports System.IO
Dim I as Integer
Dim LineText as String

VS 2005 - StreamWriter Holding File Open?

Oct 2, 2009

I'm looping through a csv file. For each line, I'm reading certain values, generating a filename, and writing the record to that file. Here is some logic

If <something that doesn't matter happens> Thendo somethingElseIf File.Exists(strOutFile & (strOutputFileName & "__" & strPrefixFileName & ".txt")) Then
strFullFileName = strOutputFileName & "__" & strPrefixFileName & ".txt" '** Double Underscores after app name
tsOutfile = New StreamWriter(strOutFile & strFullFileName)
[Code] .....

Now, obviously with the above code, there's no reason for the elseif, since they both do the same thing. The problem, however, is if I need to create a new file and write to it, everything works fine. In fact, everything will work perfectly until I need to write to a file that I already created. If I go ahead and just try "tsOutfile = New StreamWriter(strOutFile & strFullFileName)" and point it to the already existing file, I get a permission error (says the file is already open). Is streamwriter keeping an open connection to all of these files that I create? Nothing else in the program is touching these files, only streamwriter.

Here's a quick example to illustrate what is happening
Record 1 goes to file A
Record 2 goes to file A
Record 3 goes to file A
Record 4 goes to file B
Record 5 goes to file B
Record 6 goes to file B
Record 7 goes to file C
Record 8 goes to file A (Error will occur here)

VS 2005 Determine File Location Of Streamwriter?

May 14, 2009

I need to process a text file created by a Streamwriter. I have the Streamwriter object but the file location is determined by the user. The problem is, I need to process *the file* not the contents-so I need the location.

Steamwriter doesn't seem to have a Location or File property. Or am I just missing it? How can I tell what file a Streamwriter object is writing to?

Determine End Of Line Position As Integer?

Jun 6, 2011

I'm writing a text editor for my own use ( I'm "home learning") where I want to be able to leave comments for myself, like in code section of the VB express IDE. I have figured out how to get the Integer Location of the apostrophy, but can't get it to color the rest of the line. I don't know how to tell the program to find the integer value of the last character in the line. I need that to be able to subtract the apostrophy's location from the last character's location, to get the "SelectedLength". Then I can add that to the apstrophy's location to give the SelectedLength the SelectionColor.This code was thrown together from excerpts of several codes I found on the web. I had to rewrite everything to get it to do what it does so far...

Apostrophy Location is char # 534 , the end of the line is 547. ( I cheated to get that count by placing another apostrophy there, and reclicking the btn. )Anyway, I want to take 547 - 534 to get (13) the SelectionLength, then give the SelectionColor ( green) to that selected text.

[CODE]
Dim Location As Integer
Dim char3() As String = {"'"}
Dim z As Integer = CStr(vbCrLf.Count)

Search For New Line Position In A String Variable Using InStr

Aug 7, 2009

I have an application in VB.NET which gets string data from the database. This string has data which looks as below:

"This is the update: I have an issue with the application"

I need only part of the data, that comes after the new line i.e. "I have an issue with the application".

For this I am trying to search the position using InStr where the string has data in a new line. I tried many options, but they don't work.

I used "vbCrLf", Chr(13), "
", "
", "<br/>", Environment.NewLine, but none of them work.

How can I get the data I need?

Invalid Resx File Parameter Is Incorrect Line 1374, Position 5?

Oct 26, 2009

Here is my problem: I developed one application in VB.Net in VS 2008 Express Edition on MS Vista. I published the application and created the installation setup. Now when I install this application on any Vista machine, it runs without any problems, but if I install it on an XP machine, the installation is clean, but when I launch the application, it ends abruptly without any warnings/error just after the splash screen.

Then to investigate further what I did was that I copied the source project from my VS 2008 Express Edition on Vista to an XP machine having full (VS 2008 Team System) version , and when I try to compile it there (XP/VS2008 Full), I get one error in one of the forms resx file. Incidently this is the same form that gets loaded after the splash screen. So I see there is some correlation between my application ending just after the splash screen and failing to compile the main form of the application. The error that I get reads like: "Invalid resx file. The parameter is incorrect Line 1374, position 5."
