How to create new file and popup a Save As Dialog?

I want to create a new file and then popup a Save As Dialog to save the new created file.
I have tried to use the JFileChooser as the following code:
=============================================
JFileChooser jfc = new JFileChooser();
File f = new File("c:\\text.txt");
jfc.setSelectedFile(f);
int returnVal = jfc.showSaveDialog(this);
if(returnVal == JFileChooser.APPROVE_OPTION) {
f = jfc.getSelectedFile();
=============================================
I can't found the created file execute the program, anyone can tell me whats going wrong of my code or give me some advice?
Thanks a lot.

Actally, I want to generate a file and specific the
name and the location to save it.
And solution to do this if don't use the JFileChooser?Use a JFileChooser to choose a file name (you can select the directory and type the filename into a field). Once you have the file name you can open a FileOuputStream or FileWriter and write to the file you have just defined. If this file does not exist then it will be created.
If you want to confirm before overwriting an existing file then just put up a confirm dialog if the file exists (File.exists()).

How to create a file and store its contents into another file?

Hi,
I'm having some trouble trying to create a code where I have to to create a file and store its contents into another file?
I read the API, but I'm not certain how this file thing works.
Here's my code so far:
public static void main(String[] args) throws Exception
          File file = new File("tasks.txt");
          if (file.exists())
               System.out.println("File already exists");
               System.exit(0);
          Scanner scan = new Scanner(System.in);
          Scanner scan2 = new Scanner(System.in);
          //Scans the input line by line
          scan.useDelimiter("\\n");
          //Scans the input by tabs
          scan2.useDelimiter("\\t");
          PrintWriter outputs = new PrintWriter("newtasks.txt");
          outputs.print("ok");
          outputs.println(3);
          outputs.close();
     }

I managed to change my text into uppercase, but how do I store the uppercase content into another file.
-So this is what I did so far, I took a text file and modified its strings to uppercase.
-Now I need to put those modified strings into another text file, is there a way where I can do that with my current code?
-I already tried printwriter, but it doesn't seem to work
public static void main(String[] args)throws IOException
          //Task[] oneHundredTasks = new Task[100];
          String uppercase;
          String combine;
          Scanner scan = null;
          FileInputStream in = null;
        FileOutputStream out = null;
        PrintWriter output = null;
        try
             scan = new Scanner(new BufferedReader(new FileReader("tasks.txt")));
             scan.useDelimiter("\\n");
             scan.useDelimiter("\\t");
            while (scan.hasNext())
                 if(!scan.hasNext())
                      scan.next();
                 combine = scan.next();
                 uppercase = combine.toUpperCase();
                 System.out.println(uppercase);
        finally
            if (scan != null)
                scan.close();
        //The program will try the input and output files
        try
             in = new FileInputStream("tasks.txt");
            out = new FileOutputStream("newtasks.txt");
            int c;
            //The number "-1" is used to indicate that it has reached the end of the stream.
            while ((c = in.read()) != -1)
                out.write(c);
        finally
            if (in != null)
                in.close();
            if (out != null)
                out.close();
     }

Hi,
Roles are decided by IT managers. Suppose if Persons who are working in shopfloor or production side
give authorization to Production order create , change and Confirm like that etc
1. In role maintenance (transaction PFCG), choose the Authorizations tab page.
2. To change the authorization data for the transactions assigned to the role, choose Change Authorization Data or Expert Mode for Profile Generation. Otherwise, a dialog box appears in expert mode (see Regenerating an Authorization Profile After Changes).

How to create new file extension and associate an application with it?

Hi,
I want to create a new file extension named ".emsof" and
associate any text editor with it like notepad++ in windows 8.1
Moreover all of these files should be searched by having filter of "*.emsof" like any other ordinary files.
Please guide me about hoe to do it?
Thanks.

Hi BurrWalnut,
Thanks for the help.
Will this command also allow me create and save file with .emsof extension and to filter files through .emsof extension (Like we can filter through .doc or .txt extension)???
1. I don’t know what you mean by ‘filter’. In your initial post you mentioned searching, if that’s what you mean, you can search for any extension.
2. An easy to understand example of the assoc and ftype commands is a .txt file, which we all use in Notepad:
Typing assoc .txt in a cmd prompt will return txtfile (the file type).
Typing ftype txtfile will return %SystemRoot%\System32\notepad.exe %1 (the full path of the program and %1 representing a passed parameter).
Alternatively, look in the registry hive HKEY_CLASSES_ROOT for .txt and further down for txtfile.
3. If you add an entry that is later unwanted, you can easily delete it by typing assoc .emsof= and pressing Enter. Then delete the filetype by typing ftype myext= and pressing Enter. You can, of course, just delete the entries in the registry (nor recommended
for beginners).
4. Test it out now but be aware not to use extensions or filetypes that currently exist.
5. Display all extensions and their associated file types by firstly copying the following 4 lines:
assoc >"%userprofile%\desktop\assoc.txt
start notepad "%userprofile%\desktop\assoc.txt
exit
cls
Press the Windows Logo key+X (or right-click or press and hold the bottom left corner) and choose Command Prompt/Windows PowerShell (Admin). Using the mouse right-click, paste the 4 copied lines to the Command Prompt window. A .txt file is created on the Desktop
and Notepad will open and display the list. The list represents the registry keys located in the merged HKEY_CLASSES_ROOT. In the left pane, look for the extension, for example .txt. The (Default) field in the right pane contains the file type, e.g. txtfile.
6. Now display all file types and their associated programs by substituting the above 4 lines with these:
ftype >"%userprofile%\desktop\ftype.txt
start notepad "%userprofile%\desktop\ftype.txt
exit
cls
Another .txt file is created on the Desktop and Notepad will open and display it. This list represents the registry keys in HKEY_CLASSES_ROOT further down beyond the extensions. Look for the file type, for example txtfile, then click or tap shell\open\command.
In the right pane, the (Default) field shows the full path of the program that opens it, e.g. notepad.
7. NOTE. In operation, any keys in HKEY_CURRENT_USER\Software\Classes (current user) take precedence over those in HKEY_LOCAL_MACHINE\Software\Classes (all users) and both keys appear as the merged HKEY_CLASSES_ROOT. Any changes should be made to HKCU and
HKLM. The HKEY_CLASSES_ROOT keys are intended to be read from, not written to.

Quickie: Write to measurement file VI, how to create new file?

I am using the write to measurement file express VI in my code and I have wired into it a control that sets the location to save the measurement file
The only problem is the measurement file has to exist first!! I cant for example, from the front panel, click the browse directory box, navigate to a folder and type in a name for the file. It just says file not found! Its like the file directory control is opening a file to save to, rather than creating a new file in that location
How can I solve this?
Solved!

If I go in browse options what do i do? Just chose new and existing files?

Hi,
I am not sure that which option you are talking about? Are you using the EMCA,http://download.oracle.com/docs/cd/B28359_01/server.111/b28319/emca.htm#SUTIL800] to create the new repository for the EM? If not the command line than the other only way is to use DBCA(Database Configuration Assistant).I believe you are talking about that. Yes ,if the message is coming creating the repository than after wards you can login to the EM. You would get the port no of the EM's HTTP port from the $OH/install/portlist.ini file.

How to create new file folders for pics

My sd card may be corrupt, but I tried to move pictures to new folders and I get the message "Directory full". How would I normally make new folders so that I can have separate folders for different subjects?

Hi ssk600...
Attach your BB Handheld using the USB and go enable Mass Storage. You should be able to mount the phone with a drive letter on your PC. Once that is done, you can create folders using the Windows explorer shell. Create the folder and move the pictures you want into the new folder using the Explorer in XP or Vista. Once your done managing your new folder and moving your pictures, remove the USB. You will be able to see the new folder once you open up Media icon and menu your pictures on the Media Card.

How to create new file association

Hello,
I have a program that uses the .pez file extension.
Now I want to change the association so that it is opened with my desired program.
Therefore I tried:
xdg-mime default prezi-desktop.desktop application/pez
However, this does not work. The .pez file is still opened with Fileroller on Gnome 3.
How do I associate new file types with an application? The program prezi-desktop is not visible in the "Open with" menu. Hence, I cannot change the file association with Gnome.
Regards,
Robert

Hi there, I refered to this wiki page: Default Applications
Scroll down and you'll see an section titled "Gnome 3".
Basically you can try running
gconf-editor
and tinkering with settings there.
Or the more lower-level solution is to dig into either if these files
/usr/share/applications/defaults.list (global)
~/.local/share/applications/defaults.list (per user, overrides global)
Hope this helps!

Illustrator Crashes when creating new file and opening a file

Every time I try to create a new file, or even open an existing file Illustrator crashes. I have re-installed illustrator...no luck. I have tried running Illustrator while holding SHIFT...no luck. I am using windows 7, and have no crazy drivers that I believe need to be updated.
Thank you for your help!
-Patrick

Have been Googling like always after Illustrator CC crashes with these specific symptoms (Opening fine, New file of Opening existing file crashes).
All other threads had no working solution for me and the symptoms seemed little different - Opening the program and keeping it open without opening or creating a file was no problem.
This was the well-appreciated solution that did the trick for me.
Re: Illustrator CC 17.1 Crashing on New File or Open File (Win 7) works under a different user?
(In my case I think my default printer had been changed in the background by using a VPN connection this morning which I hardly use ever. Never had been thinking in that direction of course.)
Good luck to you all.
