VS 2008 Invisible Line Using Streamwriter?

Jun 4, 2010

Public Sub LecteurLogin()
'// Cr�ation du r�pertoire syst�me de CYS2011
Dim dir2 As String = "C:FicheStatsLogin"
If Not IO.Directory.Exists(dir2) Then

[code]....

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.

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"))"

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.

Way To Make The Band In The DevExpress Banded GridView Be Invisible If All The Columns Are Also Invisible?

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.

VS 2008 Datagridview Invisible Row

Jul 30, 2009

Im looking for an event that fires after a user enters a tabbed page and after the datagridview on that tabbed page is painted. BUT only fires on the load, not every single time the datagridview is painted. I am making rows in the datagrid invisible to the user based on wether or not a checkbox in the row is checked.

If I do this on the Tab_Enter event it paints the datagrid before I can loop through the records and change the visible property And if I do this on the Datagridview_Paint event it fires everytime the datagrid is painted (I only want it to fire once)

VS 2008 - Invisible Treeview Nodes

Jul 3, 2009

I have a form with a treeview control (trvControl) which is created at design time. I have a sub which creates a temporary treeview (trvTemp) and adds a bunch of nodes to it. It then uses treeview.nodes.copyto and treeview.nodes.addrange to copy these nodes to the control on my form:

[Code]...

It all seems to be working except for one thing - nothing appears in trvControl.
I've run through the code and the node collection is definitely getting copied (I paused in another sub and checked trvControl.nodes and it was correct) but trvControl is still empty on my form.

Incidentally, the reason I am doing this is that I want to use a background worker to populate the nodes but don't want my app locking up for large amounts of time while I access the treenode through an invoke so I thought if I generate the node collection first and just use the invoke to load it into the array it would work better.

2008 - Error: StreamWriter Destination Unreachable

Mar 3, 2009

I am using the Streamwriter to send simple messages to other machines in my office. But i hit across a problem today which i never thought about. If the computer im sending the message to, doesn't have the listener running, the sender crashes out. Is there anyway to trap the error, and deal with it nicely (i.e a message box) instead of the app quiting?
