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.

I am using streamreader and streamwriter to read a text file , change the text, then write to the same text file. This all happens in a loop every second or so.Currently I use:
Dim csetpointfileread As New System.IO.StreamReader("C:webcsetpoint.txt")and Dim csetpointfile As New System.IO.StreamWriter("c:webcsetpoint.txt", False)before every file read / write operation, it gets dimensioned every loop. To me this seems like a waste, and should only have to be dimentioned once. If I try to run both statements in the beginning, outside of the loop, the second statement wont work because the "file is allready open". Am I missing something or am I doing it correctly to begin with?

I am writing a click event to delete an item selected from a list view which will utlimately be deleted from the csv file the information is coming from.Currently I am having streamreader read each line and then replace the selected line with a blank line. This creates blank lines in my csv files. Is there a way to delete a line using sr or sw without creating blank lines?Or is there a way to have them read/write a file skipping any empty lines?

I'm creating a text file and, among other things, I need to write the text of the parent and child nodes of a TreeView to the file. I know how to write the contents and read them just fine, but what I can't seem to figure out is how to write the contents if I don't know how many parent nodes or child nodes there are. When I do, I usually do the following:

To automate mailmerge function in word, i need to join different elements to complete the mailmergedatasource. In one of these file are words with special characters like ©, §,¨, .... When openng these files for reading, streamreader transfoms the characters to unreadable signs. When i give a type to use to open like ASCII, Unicode,it works for one or tho characters but not for all. I have the same problem when the character is read correctly, with streamwriter output to a textfile. Word cannot read the textfile and ask to define which type of coding should be used. In most of the cases not all the characters can be converted to readable characters.

In my code I've allowed used to create their own mazes and save them, under whatever name they like. I've also included a few pre-created mazes. The mazes themselves are saves in .txt files in the bin/debug folder of the project, along with a .txt file containing the maze names.
I really need to publish this program to send it to my teacher, but when I publish it it doesn't include any of the .txt files in my bin/debug folder.

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 made my own advanced networking system which uses System.IO.Streamwriter and Streamreader but offline. I would like to let this use a directory online, I have a webhost available for that, now how do I say to the program it has to look at a specific map with all the users information?
I now have already this into my login form:

Just curious if I can let my network grow out international instead of pc. Also I have a second question. I made a create account page which is supposted to make a text file with the txtUserName and txtPassword inputs, but it does create the file, but doesnt write any lines into it.

My problem is when the file I am reading contains an accented character the streamreader simply ignores this character. So if the line I read in was a 10 bytes line, it now only writes back out a 9 byte line. This is a huge issue as the file I am working with has to be a fixed length. I know there is some encoding that can be done to make this work, but know very little about it. [Code]

I am looping through a text file and reading and then parsing each line.. then, inserting into a sql server. The problem is, I am getting every other line. Any thoughts? I read another post on here that is similar and it says that that person was calling the ReadLine twice... which makes sense. I just cannot spot where it is happening.

I'm having an issue with the streamreader. I had it working but I've changed something and it has stopped.
I have it in a Do While loop reading line by line, but it doesn't finish reading. It reads about 27 lines out of 4000, then stops.
I changed the contents of the file it was reading, but it's still just save as a txt notepad file.
I also changed how I tell it which file to open (UserSelection.T2) however it does open the file just doesn't finish reading it.
Doesn't kick back any errors, it just doesn't read the entire file.

Ok, so I got everything working except for one thing. My program stores text in a settings files (which it saves to and encrypts to wonderfully), but it will only work once. For example, I type in an author, title and body, and click Publish, it publishes and is labeled with a "1.". Restarting the application, you get the desired effect, a decrypted string from the encrypted settings file, now publish another entry, this makes a new line with "vbNewLine" and then encrypts it, fine and dandy. Now apon opening the application again, you get an error stating "Invalid character in a Base-64 string.". What do I do?

I'm writing a program and it's got a textbox for the user to enter values. Since the textbox text property should only be a "number", my program need to detect invalid charaters like "*/&()$" and tell the user to only enter a number. Does anyone have an idea how to do that?

What I have stored in my file is values related to an account. (Just testing, not going to be used commercially). What I need is to draw the values for the username and password, by going through each new line, but .peek() doesn't seem to work for me.
My block looks as such :
public string CheckAccount(string username, string password) {
StreamReader sr;
string filename = "H:\AccountInfo.txt";
string s;
string result = "";

My code doesn't read from the 2nd line onwards, it just hangs.
