thanks MariusMM but ive allready written that ive got the create code for the file. but no problem
maybe u sadly dont understand my problem so i explain it:
with this code above you and i have posted we can create a file like this:
_____________________________
|Filename.txt
|--------------------------------|
| Admin = Grinch
| Admin = MariusMM
| Adm....
|
|____________________________|
But i need a code wich i can delete this things, ill explain that too:
if i type as example "!lockadmin [username]", that its deleting the users Admin "rights" and it should delete the users: "Admin = username".
So the code wich i search should to the opposite
Thats what i mean
Did you or anybody got any clue
maybe dougie-lampkin personaliy? ^^ cuz he has written the code
So you want to take a specific input (in this case the driver's name) and remove it from the "Filename.txt" file if it appears there?
What I would normally do in this case is to create a secondary file and copy all the contents of the "Filename.txt" file into that secondary file EXCEPT for the line you want to delete. Then when you've copied the file you delete "Filename.txt" and rename your secondary file "Filename.txt.temp" or whatever you call it to "Filename.txt". There are other ways to do it (like reading all of the contents of "Filename.txt" EXCEPT for the line you want to delete into a Vector or some temporary data structure in memory then just creating a new file by outputting all the data from memory, but I think the first way is probably the easiest.
Here is some code from my custom resolution launcher for LFS that demonstrates the first method (but rather than removing the line entirely I'm just modifying some of it). It's in Java, so you might not understand all the syntax but hopefully it gives you some inspiration. Good luck.
private void outputDetailsToCFGFile() { /* * Output the details the user has specified to file. Create a temp file and * to hold the contents of the updated cfg.txt file then delete the original * cfg.txt file and rename the temp file to cfg.txt */ // The original config file File configFile = new File(CONFIG_FILENAME); FileReader configFileReader = null; BufferedReader bufReader = null;
try { configFileReader = new FileReader(configFile); bufReader = new BufferedReader(configFileReader); } catch(FileNotFoundException fnfe) { // Can't find the cfg.txt file, exit the application JOptionPane.showMessageDialog(null, "The "+CONFIG_FILENAME+" file cannot be found at the following location:\n" + configFile.getAbsolutePath()+"\n" + "Try running LFS on its own to create the "+CONFIG_FILENAME+" file then re-run this application.", "Cannot Find Config File", JOptionPane.ERROR_MESSAGE);
System.exit(1); }
// The temporary config file File newConfigFile = new File("temporary"+CONFIG_FILENAME);
try { newConfigOutputStream = new FileOutputStream(newConfigFile); writer = new PrintWriter(newConfigOutputStream); } catch(FileNotFoundException fnfe) { fnfe.printStackTrace();
JOptionPane.showMessageDialog(null, "The application cannot write the details of the new config file.\n" + "Please report this problem in the LFS Forum thread you downloaded the application from.\n" + "Include as many details as possible (including Operating System, Java version, " + "folder you're running this app from).\n" + "Thanks.", "Cannot Write New File", JOptionPane.ERROR_MESSAGE);
System.exit(1); }
/* * Read files from the original config file. If they are not relevant to this application simply * output them to the new config file. If they are relevant update the information as necessary * and output it */
try { String inputLine = bufReader.readLine();
while(inputLine != null) { if(inputLine.startsWith(SCREEN_MODE_LINE_IDENTIFIER)) { if(debug) { print("Found the screen info line in config file: "+inputLine); }
// If the colour depth isn't set here it needs to be retained from current file if(colourDepth == Integer.MAX_VALUE) { // Get the details in the current screen info String currentDetails = inputLine.substring(inputLine.indexOf(SCREEN_MODE_LINE_IDENTIFIER)+ SCREEN_MODE_LINE_IDENTIFIER.length()+1);
// Horizontal res toOutput.append(horizontalRes+" ");
// Vertical res toOutput.append(verticalRes+" ");
writer.println(toOutput.toString()); } else { // Otherwise just output the new details StringBuilder toOutput = new StringBuilder(SCREEN_MODE_LINE_IDENTIFIER+" ");
JOptionPane.showMessageDialog(null, "The application cannot read or write the config file.\n" + "Please report this problem in the LFS Forum thread you downloaded the application from.\n" + "Include as many details as possible (including Operating System, Java version, " + "folder you're running this app from).\n" + "Thanks.", "Problem Reading Or Writing Config File", JOptionPane.ERROR_MESSAGE);
System.exit(1); }
// Now the temporary config file contains the updated details delete the original file and rename new one boolean originalFileDeleted = configFile.delete();
if(!newFileRenamed) { JOptionPane.showMessageDialog(null, "The application cannot replace the original config file (2).\n" + "Please report this problem in the LFS Forum thread you downloaded the application from.\n" + "Include as many details as possible (including Operating System, Java version, " + "folder you're running this app from).\n" + "Thanks.", "Problem Replacing Config File", JOptionPane.ERROR_MESSAGE);
System.exit(1); } } else { JOptionPane.showMessageDialog(null, "The application cannot replace the original config file (1).\n" + "Please report this problem in the LFS Forum thread you downloaded the application from.\n" + "Include as many details as possible (including Operating System, Java version, " + "folder you're running this app from).\n" + "Thanks.", "Problem Replacing Config File", JOptionPane.ERROR_MESSAGE);
Its not working at all
im using the code from MariusMM.
but ive read in an C# forum that its not possible to delete some line in a textfile in C#
the only method is to save the complete text in a .temp file ,remove the line wich you dont need/want, save into the old file.
Yeah, that's what I was trying to demonstrate above. I don't have a C# IDE installed at the moment but what you want to do is to set up 2 different FileStreams. One in read mode (to read in your "Filename.txt" file) and one in write mode (to write out the temporary copy "Filename.txt.temp"). Then you read one line from the "Filename.txt" file into a string. Once you've read it in you want to look at that string and decide if you want to keep it or you want to get rid of it. If you want to keep it you write it out to your "Filename.txt.temp" file. If you want to get rid of it (because it contains the name you want to delete) you don't write it out to the "Filename.txt.temp" file. Do that for all of the lines in the "Filename.txt" file. Then once you're finished delete the "Filename.txt" file and rename the "Filename.txt.temp" file to "Filename.txt".
No, he doesn't just want to delete a file. He wants to remove a specific line from a file. Say the file contained the following:
Admin:amp88 Admin:Marco1 Admin:Grinch
He wants for an admin to type a command like "!removeadmin amp88" and for a function to go through the file looking for the line "Admin:amp88" and remove it from the file. That way the file would end up looking like this:
@Marco1
Thats it!!!!
Then i just need to delete the whole file
e.g
ive got this database just as example:
C:\.....\Database\Admins\Grinch.txt as Admin database
C:\......\Database\Users\Grinch.txt as Normal user database
and
C:\......\Database\Moderators\Grinch.txt as Moderators database
YEA HELL IVE GOT IT!
sorry for swearing ^^
Mega best regards to the best community of the world! Grinch
That's what I do when I need to delete a simple line...
As a creator from an finished Ranking System, I really suggest you to drop that txt shit, and start with a MySQL database. I'm currently rewriting the system into C# and with a MySQL database. This database is a lot more easier to work with, although its syntax has some slight differences from the PHP Mysql, and it's enormously faster.
Alternatively if you just want a database for your .NET app, nothing fancy, then consider SQL Compact. You can include a database with your app without any additional dependencies.
Isn't a database wich is located on your own computer safer? as one wich is on an webserver?
And can i run an MySQL database on my home located computer?
Q1:
Yes, but then your computer has to be online 24/24 7/7. Well, if you use a database which is really located on your computer and not on the hosts computer. I would suggest using a web server because from there you can easily connect your ranking database to a PHP site which shows the current (and updated) rankings on the site.
Although an online MySQL database is very save too if you don't connect it to a site for example where users could enter ... how's it called again... MySQL injections.
Q2:
Yes, you can run a MySQL database from your own computer (from your localhost). You need a program for this. The program I use is called XAMPP and you can download it here: http://www.apachefriends.org/en/xampp-windows.html#641
It's a very user friendly tool if you want to setup a database.
Some quick information:
Install Xampp, open it, activate the MySQL part, open your browser and fill in the URL: localhost/phpmyadmin
It can get a bit new if you never done it before but the site I gave you earlier (about the MySQL queries from a .net application) will help you alot. If you have experience using PHP in combination with MySQL, you're one step ahead.
