To write a series of strings to a file. Loop through the string collection. Use the WriteAllText method to write text to a file, specifying the target file and string to be added and setting append to True. This example writes the names of the files in the Documents and Settings directory to FileList.txt, inserting a carriage return between each for better readability.
Note you don't need to do a loop to write. sFinal contains the complete text of the File ready to be written at one shot. Note that input reads a LINE at a time so each line appended to sFinal needs to have a CR and LF appended at the end to be written out correctly on a MS Windows system.
If an application needs to create a file, that application needs Create access for the folder. If the file already exists, the application needs only Write access, a lesser privilege. Where possible, it is more secure to create the file during deployment, and only grant Read access to a single file, rather than Create access for a folder.The StreamReader and StreamWriter classes are used for reading from and writing data to text files. These classes inherit from the abstract base class Stream, which supports reading and writing bytes into a file stream. The StreamWriter class inherits from the abstract class TextWriter that.I have used streamwriter in vb.net, but I am trying to write a simple VB6 application and still write to a text file. I think I should be able to use streamwriter, but I can't get it to recognize it.
After you finish using a file, you should close it with the Close statement (refer to Listing 21.1). This way, you can free up the file number for use with other files. In addition to providing the filename and number association, the Open statement tells Visual Basic how you intend to use the specified file. (Many different options are available with the Open statement, as discussed in the.Read More
