This append feature does not seem to work. I've looked in many places to no avail. The other examples below for writing and reading seem to be going fine.

Dim objWriter As System.IO.StreamWriter = file.appendtext("textTBD")
objWriter.WriteLine("textTBD")

I'm appending string variable text after appending a line throws System.OutOfMemoryException?
Can any one explain why it is throwing error.
str+="something Text"
str+="something Text"
and lastly I assign it to a lable text When I assign the value of str it throws exception.....
How would I go about appending text to a Textbox without losing the current scrollbar position? I thought somehting as simple as:
Textbox1.Text += "MyString" & vbCrLf
would work, but it just sends the scrollbars to the top.
Lets assume I have a DataSet that contains the following info (columns seperated with | character):
1 | Logan | Young
2 | John | Doe
3 | Jane | Doe
4 | Joe | Soap
If I now write this info to a text file, but later want to append 5 | Susan | Sarandonto the end of the text file, I obviously want to check that the text file doesn't already contain the data that I want to append to it. I'm having a little difficulty figuring out how to perform this check...I know you'd have to loop through every row in the DataSet's table and compare it to every line in the text file. That part's easy.
We are trying to Open a text file and if our needed information isn't in there, we need to write it, otherwise we need to append to the existing text. We had it working in VB6 (below) and i havent the slightest clue
CommonDialog1.Filter = "Text Files (*.txt)|*.txt"
CommonDialog1.FileName = frmSplash.fp & "\job_info\" & nam
Open (CommonDialog1.FileName) For Append As #1

I have a VB 2008 program which shows the user's results in a ListView, and permanently stores them in a Notepad (.txt) file. The program works fine when I run it using Debug. The permanent records show up on a .txt file in the "bin". However, I want to publish the program as an executable file. I have tried this using my normal method of selecting "Publish" from the "Build" menu, and my program runs fine but there is no .txt file to be found.
View 3 RepliesThe user starts out by pasting text into a textbox:
1.Phototypesetting was superior to automated typesetting because it was

(B)Faster
(C)More flexible
*(D)All of the above
What I want to do is to tag the sentence and format it as follows: MC Phototypesetting was superior to automated typesetting because it was (A)Easier incorrect (B)Faster incorrect (C)More flexible incorrect (D)All of the above correct Using the following code I can easily replace the number (1) with MC:
TextBox1.Text = Replace(TextBox1.Text, ("1."), "MC ")
But for the life of me I cannot figure out how to tag each choice with correct or incorrect. The correct tag will go to the end of the choice which starts with * eg *(D) All of the above correct, while incorrect should go at the end of all other choices.
Stuff like this makes me hate computers! Anyways, I'm again struggling with something relatively simple - or so i thought.I have a sub:
[Code]...
Then, I have a sub that runs every minute, calling yet another sub, which calls this one. Before you say whoa! that's too many, I'll say that each of these subs has a different purpose.The whole problem is that the WriteToFile sub writes only once to a file! Instead of continously writing to the file every minute, it stops at the first line.
I have a piece of software that can be used either on an admin account or a standard user account of a completely stand-alone, Windows XP machine.
I have also set up some log files that the system uses when it either performs an admin function or if an error occurs. the location of these files is a C: location - not (from what I can see) associated with the admin account in any way.
When running the software from the admin machine, the log file is appending fine. When running the software from the standard user machine, the log file causes an error, suggesting that "Access to the path 'C:HNP MTWP Log FilesAdministrative ToolsAdmin.log' is denied.
This error occurs when first setting up the FileStream. Here is my code.

Is it possible to append text to a text file located on a webserver from a winform? If so, can you please point me in the right direction. I've searched this forum but can only find documentation on appending a local text file.
View 2 RepliesI 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.

View 4 RepliesWith the intention of creating a program to interface with a serial port device, I recently started learning vb.net. To keep the structure neat the vb code has been split into two places; the first is the code behind for initialising, clicking buttons etc., whilst the second is for managing the comm port. Respectively, these are named 'MainWindow.xaml.vb' and 'ComPortManager.vb'.
In 'comPortManager.vb':

I'm trying to find a way to change the color of one word when appending text to a Rich text box. So if I append the sentence "This is a sentence with a specific word in one color" The entire thing will be in black except for the word "specific" it will be in red or any color I choose. The same thing will happen if the next line appended is "Please be specific in your request". All back except for the word "specific". I don't want the text added then someone has to click a button to change the color. It should happen as it's appended.

I would like to know how it's possible to append text between data.
For example:
I have a RTB with "ABC" on the first line and "DEF" on the third line. My question is how would I insert text data into the second line, without changing any existing data.
I am reading text from a file (*.TXT) 1 line at a time using streamreader. As I read that input, I am looking for specific starting and ending character strings ("<" and ">") . When I find those strings, I would like to select the characters between those string and have it set to BOLD and BLUE before appending that input line to the contents of a richtextbox.The only way I have found to do this is to first append the input line to the richtextbox then use the richtextbox.selection (color and font) methods to change the text.

When the button is pressed the line is written to the file just fine, but if I restart my application, which calls Refresh_OtherLog() onLoad, it displays the lines of the text file as one line with the traditional square character depicting a character return. Why is it not putting that new lone as a new line in the listbox?

All right, here's my issue. I have a resource that is a text file. I'm trying to use a StreamWriter to edit it. I've done it in C# but can't find my example files.
View 3 RepliesI am writing each line to a text file:
Dim objWriter As New System.IO.StreamWriter(filename)
For Each x In tofile
objWriter.WriteLine(x)

objWriter.Close()
Which works perfectly the only problem is is that when its finished it writes a blank line on the end of the text file which I don't want.
I am trying to use filestream and streamwriter / streamreader to have a simple text box where the text entered is written to a text file, and then a button can be clicked to read the file and present the text back to the textbox. It works, but the problem I'm having is that if i change the text to something smaller in length (less text) than what is currently in the file, then press the button to read the file, it still contains some of the old text that was previously in the file.
Dim strmReadFile As New FileStream(txtPath.Text, FileMode.Open, FileAccess.Read, FileShare.Read)
Dim readHandle As New StreamReader(strmReadFile)
'read the entire text, and set it to a string
Dim streamFileContents As String = readHandle.ReadToEnd()

I'm getting a problem when writing text files using StreamWriter. The files read fine and they write fine if I'm not overwriting an existing file. They also write ok as long as I'm not writing over a file that only has one digit at the end of the name. For some reason when there are 2 digits at the end it crashes when I'm trying to save over an already existing text file. Here's my code.
StringForTextFile = "C:" & Folder4PS & "" & IDCodewDashOrN & "Series" & Series & "ScreenNumber" & ScreenNumber & ".txt"
LblTesting.Visible = True ' Testing
LblTesting.Text = "StringForTextFile = " & StringForTextFile
[code]....
above but 've tried all the different Encoding possibilites. Unicode, UTF32, UTF8, UTF7 as well as without those parameters listed where the close parentheses is right after StringForTextFile. I get the same result. If I'm writing a new text file that doesn't exist, then no problem or if I'm writing over an existing text file but it has 0 to 9 at the end then I'm ok but if I'm writing over an existing file and there is 10 or above(haven't tried triple digits or all values) then my application crashes. You see the test label in the code above because I was looking at exactly what file it was trying to overwrite and it is just as it should be.
Should I be using a different procedure? An example of a string that would cause a crash for the string StringForTextFile would be:
C:Name of My AppSeries1ScreenNumber10.txt
If it was being written for the first time then no problem or if the 10 at the end was 0 to 9 then no problem also. I've also tried and originally had it set up where there wasn't an If File.Exists(StringForTextFile) = True Then statement. It just always used the same code whether writing or overwriting and I wasn't having a problem that I remember. For some reason I started having a problem recently and I put the alternate methods of writing in.
I am new to the forum I have been working on a GUI to export verification data to a text file.
