How can I enable Safari's ability to display pdf files?

Hi there,
In Safari 4.0.3 (MacBook Pro) pdf links open as a dark grey block. That is, instead of the intended text, I see just dark gray.
Control-click allows me to save the file to the desktop in which case Preview can open them with no problem.

HI,
If you have Adobe Acrobat Reader, launch Adobe Reader. From the Menu Bar, click Adobe Reader/Preferences. Select the Internet category...the top option is the one you want. Uncheck the box to make sure Adobe doesn't keep making itself the default reader.
You might also need to open /Library/Internet Plug-Ins and delete Adobe's PDF viewer plug-in.

How to change the default save encoding of the dvm files when create dvm???

When I creating a DVM(domain-value mapping) in Chinese on the ESB control and confirm it, then restarted the SOA service, the DVM that I created in Chinese disappeared from ESB control. All the maps(both English and Chinese ) are in DVM Repository.
After I updated the encoding from ‘UTF-8’ to ‘GB2312’ in the three files below, and restarted the SOA service, the DVM in Chinese appeared on ESB control.
But when I adding the second row in Chinese and save it, then restart the SOA service, the DVM in Chinese disappeared from ESB Control once again. Because the encoding in the three files below is updated from ‘GB2312’ to ‘UTF-8’ .
Files:
C:\product\10.1.3.1\OracleAS_1\integration\esb\oraesb\artifacts\store\metadata\files\dvm.def.xml
C:\product\10.1.3.1\OracleAS_1\integration\esb\oraesb\artifacts\store\metadata\files\dvm\Chinese.xml.def.xml
C:\product\10.1.3.1\OracleAS_1\integration\esb\oraesb\artifacts\store\content\files\dvm\Chinese.xml_1.0

I have the same problem. When I updated to Mavericks now the bookmarks bar font is huge. I liked it the way it was before. I liked the smaller font. Also wish I could change the color of the sidebar and font/folders too.
I tried to see in preferences if there was anyway to change it, but I don't see anything there.

After aquiring an image how do you convert or save it as an HDF file

I am using LV to acquire an image. Once I grab the image I need to save it as an HDF file so I can do some further analysis. Has anybody done this if so could you explain how to go about it?

There is a LabVIEW toolkit that will enable you to edit and save files stored in HDF (Hierachical Data Format) You might consider reading the following knowledgebase:

How to only read the last line in the text file by using BufferedReader ?

Dear all,
Hello, I am new to Java. Do anybody know how to read the last line (this is the last record) in the text file.The method I am now using is reading from the first line until I reach the last line in the text file. Thank you!!
BufferedReader br = new BufferedReader(new FileReader("c:\\sdk1.4.1\\bin\\dbExport.txt"));
DataInputStream in = new DataInputStream(new FileInputStream("c:\\sdk1.4.1\\bin\\dbExport.txt"));
String input;
String firstinput;
String secondinput;
int count=90;
int year=1955;
while ((input = br.readLine()) != null) {
firstinput = input.substring(0, 10);
secondinput = input.substring(10);
String insertStore1 = ("INSERT INTO AUTHORS " +
"VALUES ('" + count + "', '" + firstinput + "', '" + secondinput + "', 1955)");
System.out.println(insertStore1);
int result = stmt.executeUpdate(insertStore1);

I suppose you could use a java.io.RandomAccessFile.

How can I enable Texture filters on a 16 bit file in Photoshop CC?

I am trying to use the texture filters in Photoshop CC and when I try to open them on a 16 bit file the texture category is grayed out. I have a method from a Peachpit article by Helen Bradley that uses texture filters to apply a border around an image. How can I enable texture filters?

If you are talking about the Filter Gallery, you can't use that on 16 bit files. What you can do is duplicate the current 16 bit file and convert to 8 bit, run the various filters to get the border around you image than take the border from the 8 bit file and copy/paste it back into the 16 bit file...

How do I open and save a DVD as movie file?

I have a DVD with video content that I want to eventually get "in" to iMovie for editing.
I can open and play with iDVD.
I need to save it as a movie file so that I can hopefully import it to iPhoto - and eventually open and edit with iMovie.
How do I save it as a movie file? When I tried QuickTime it wasn't able to open it either.
Thanks,
Kathy

Did you load the MPEG2 Playback Component?
If you open your DVD in the Finder, you should find a folder called Video_TS. In this folder, you should see several files with the extension .VOB. Drag one of these files into MPEG Streamclip and you should be able to play it. If you get that far, we'll keep going.
AIC is Apple Intermediate Codec. It is a high quality codec good for editing. DV is the codec used by MiniDV camcorders. You can pick these in MPEG Streamclip by selecting FILE/EXPORT TO QUICKTIME/AIC or FILE/EXPORT TO DV
There are other solutions, but this is the best one if you want to preserve the quality of your files before editing.

I cannot activate LR5 and find 2 hosts file in html. not sure how to proceed from now

i cannot activate lr5
Contacted help desk and found the info on the site but i ma supposed to copy the hosts file and remove reference to adobe activation. issue is that i see two host file but in html format. how am i supposed to do this? sorry, am not a techy.

What operating system are you on?
Win: - How can I reset the Hosts file back to the default?
Mac: - restore orginal host file | Apple Support Communities
Or get in contact with the support of the Operating system and ask them to guide on getting the Host file restored.
It is a System Related file, they should be able to assist you in restoring it to default.

How to make the Open/Save dialogue download the text file instead of JSP

I am currently coding on a JSP program, which searches the database and writes the resultset into a file on the server, and then allows the client to download this tab delimited text file onto their local machine. But I met a problem, when the default Open or Save dialogue appears, it shows that it's trying to download the running JSP file from my local host instead of the newly-created text file. Despite this, when I click OK to either Open or Save the file, a warning dialogue will appear saying: The explorer cann't download this file, it's unable to find this internet site or something like that. I get no error message from the server but I was always told that Javax.servlet.ServletException: getWriter() was already called. What does this mean?
I guess maybe this is caused by the mix use of outputStreams in my program. I don't know if there is a way to directly read the resultset from the database and then send it through outputStream to the client. My solution is: first create a file on the server to hold the resultset, and then output this file to the client. I did all these in one JSP program: Create file on the server, search database, and then read file and output the contents to client. Is this correct? I attached my code, please feel free to correct any of my mistake? Thanks!

Thanks. I believe something wrong with this statement
in my program:
You are correct there is something wrong with this statement. Seeing how you are doing this in a jsp, not really what they're made for but thats another topic, the output stream has already been called. When a jsp gets compiled it creates a few implicit objects, one of them being the outputstream out, and it does this by calling the response.getWriter(). getWriter or getOutputStream can only be called once, other wise you will get the exception you are experiencing. This is for both methods as well, seeing how the jsp compiles and calls getWriter means that you cannot call getOutputStream. Calling one makes the other throw the exception if called as well. As far as the filename problem in the browser goes I'm guessing that it's in IE. I've had some problems before when I had to send files to the browser through a servlet and remember having to set an inline attribute of some sort in the content-dis header inorder to get IE to see the real filename. The best way to solve this is to get the orielly file package and use that. It is very easy to use and understand and does all of this for you already. Plus it's free. Cant beat that.
ServletOutputStream outs =
response.getOutputStream();
because I put a lot of printout statement within my
code, and the program stops to print out exactly
before the above statement. And then I get the
following message, which repeats several times:
ServletExec: caught exception -
javax.servlet.ServletException: getWriter() was
already called.

How can i read all the lines from a text file in specific places and use the data ?

string[] lines = File.ReadAllLines(@"c:\wmiclasses\wmiclasses1.txt");
for (int i = 0; i < lines.Length; i++)
if (lines[i].StartsWith("ComboBox"))
And this is how the text file content look like:
ComboBox Name cmbxOption
Classes Win32_1394Controller
Classes Win32_1394ControllerDevice
ComboBox Name cmbxStorage
Classes Win32_LogicalFileSecuritySetting
Classes Win32_TapeDrive
What i need to do is some things:
1. Each time the line start with ComboBox then to get only the ComboBox name from the line for example cmbxOption.
Since i have already this ComboBoxes in my form1 designer i need to identify where the cmbxOption start and end and when the next ComboBox start cmbxStorage.
2. To get all the lines of the current ComboBox for example this lines belong to cmbxOption:
Classes Win32_1394Controller
Classes Win32_1394ControllerDevice
3. To create from each line a Key and Value for example from the line:
Classes Win32_1394Controller
Then the key will be Win32_1394Controller and the value will be only 1394Controller
Then the second line key Win32_1394ControllerDevice and value only 1394ControllerDevice
4. To add to the correct belonging ComboBox only the value 1394Controller.
5. To make that when i select in the ComboBox for example in cmbxOption the item 1394Controller it will act like i selected Win32_1394Controller.
For example in this event:
private void cmbxOption_SelectedIndexChanged(object sender, EventArgs e)
InsertInfo(cmbxOption.SelectedItem.ToString(), ref lstDisplayHardware, chkHardware.Checked);
In need that the SelectedItem will be Win32_1394Controller but the user will see in the cmbxOption only 1394Controller without the Win32_
This is the start of the method InsertInfo
private void InsertInfo(string Key, ref ListView lst, bool DontInsertNull)
That's why i need that the Key will be Win32_1394Controller but i want that the user will see in the ComboBox only 1394Controller without the Win32_

Hello,
Here is a running start on getting specific lines in the case lines starting with ComboBox. I took your data and placed it into a text file named TextFile1.txt in the bin\debug folder. Code below was done in
a console app.
using System;
using System.IO;
using System.Linq;
namespace ConsoleApplication1
internal class Program
private static void Main(string[] args)
var result =
from T in File.ReadAllLines(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "TextFile1.txt"))
.Select((line, index) => new { Line = line, Index = index })
.Where((s) => s.Line.StartsWith("ComboBox"))
select T
).ToList();
if (result.Count > 0)
foreach (var item in result)
Console.WriteLine("Line: {0} Data: {1}", item.Index, item.Line);
Console.ReadLine();

Import-csv how to make powershell ignore a line in a csv file if a column contains a certain value

Basically I got a very basic script that uses a csv file to input values needed to remove people from a distro list. That part is working fine. I'd like to add to it's functionality so it can look at values in a certain column, and if any of those certain
values are present, I want powershell to skip that line and not process it. For instance I have a column in the csv called Group. If I have a listing under Group that says ABC I want the script to skip that line and not try to process it. What could I insert
into the script to acheive this?

You're welcome. You can add to the if test with -and:
Import-Csv .\groups.csv | ForEach {
If ($_.Group -ne 'ABC' -and $_.Group -ne 'DEF') {
Write-Output "Group is $($_.Group)"
Write-Output "Name is $($_.Name)"
Output:
Group is GHI
Name is Show Me
groups.csv:
Group,Name
ABC,Skip Me
DEF,Skip Me Too
GHI, Show Me

How can i get and save the name of the file

Hi all
in my program i'm dealing with several text files each has its own name
after doing some process on each i do save the output as output.txt
can i add the file name before or after the output.txt
i.e i want the name of the file to be part of the saved output
filenameOutput.txt
or
outputFilename.txt
any ideas?????

Just write it - somewhere in your code you have to have the file name anyway, or you couldn't write to that file.
