How to save a Cyrillic font string

Dear all,
I have an application which I can display Russian character, but when I save to an image file (it is a format defined in our company), the display is mess. We have a workaround to realize this: if you set your default local to China then it is OK. But our user is not in China so we can't ask them to set this. I feel very strange about this, I also tried to output unicode (UTF-8) but it does not work. Anybody has idea?
Thanks
Samuel

How can you "save" a string in an image file? Don't you mean that you try to draw it?

How Do you use Cyrillic Fonts (Russian) in InDesign CS4 or CS3

I have a headline in Russian a client sent me in an e-mail that I need to use on a poster I'm laying out in InDesign.
I downloaded ERUniverse cyrillic font, and when I paste the Russian headline in a text box and go to select ERUniverse cyrillic, there's no Russian!
Also, I go down to the bottom of my fonts there's Hebrew, Japanesse, Chinese fonts, etc...but no Russian.
Please help with instructions on how to use a cyrillic font!!!

I downloaded ERUniverse cyrillic font, and when I paste the Russian headline in a text box and go to select ERUniverse cyrillic, there's no Russian!
That font must not be Unicode enabled. An old hack to insert Cyrillic characters into a regular font was to replace "unused" characters with Cyrillic ones. So, to type a 'de' д, you would insert the character code for an 'ê'.
Modern fonts are Unicode enabled, which simply means that in every font Cyrillic characters are found in the same place. Thus, changing the font does not change the text.
If you are working on Windows, check the Character Map for fonts that support Cyrillic. Select 'Advanced view', Character set: Unicode, Group by: Unicode Subrange. A small window pops up, enumerating all possible Unicode groups. Scroll down and select 'Cyrillic'. Now the character map will only show these characters for each font, so simply scroll through your font list to see which one have them.
(And OSX no doubt has a similar feature.)
The older Windows system fonts Times New Roman, Arial, Georgia, Verdana, and the newer ones Calibri, Cambria, and Candara, and lots of the fonts that came with your InDesign installation support Cyrillic (at least Minion Pro and Myriad Pro do).
It's also possible the original text has not been typed using a Unicode font. If you need a quick check, select some of the text and select the font Arial Unicode (on a Mac, I think "LastResort" will do). If you see useful text, you're okay to go. If not, you have a huge problem. You will have to find the exact font that was used in the original document and use that, or use Find and Replace to change each character to the actual Cyrillic one (and you will need a hardcopy before you can do that).

How to save data in a string control?

I want to save data in a string control or indicator. I know that I can rt-click and make the data default. But can it be done through a proberty node or something else when the program is running?

There isn't a "Make Current Value Default" method that you can invoke programmatically, this would require your VI to be saved when it was closed, which obviously couldn't be done if it had been built into an executable.
You could read the values from the controls/indicators and save them in a .ini file using the Configuration File VIs on the File I/O palette, and have some code at the start of your program that reads the values from the file and puts them into the objects using local variables.

How To use Arial (Cyrillic) font in Reports 10g for PDF output

Hi,
My reports are in Arial (Cyrillic) font, but there are only hieroglyphes in pdf output. Is there a problem with fonts on Report Server or something else?
My Report Server is 10g R2 (10.1.2.2) and OS is RHEL 4.
I followed metalink notes 750805.1 and 356221.1 but it didn't help me.

You also have to be careful with fonts. The font you download may be the same name, but a different font. Just because you find a Zurich BT font, does not mean it is the same. If you search on the internet, there are several sources of some Zurich BT fonts free. However, they may or may not be the same font. Editing is best done on the original document and not the PDF. One of the PDFs I found on the Landis site was only in Zurich font. I would think that the original file is available from the company and that should be the document you edit, not the PDF. It appears the original was created in InDesign (CS3).

Hi, How to save UTF-8 encoded string into Mysql DB with jdbc?

Mysql doesn't support UTF-8, right? is there any way we can bridge it?

Hi,
By using the latest versions of MySql and mm mysql jdbc drivers you can
read and write unicode characters from/into MySql database. You can download
mm.mysql jdbc driver from http://mmmysql.sourceforge.net/
We haven't tested this jdbc driver officially.
Hope this helps.
Good Luck.

How to save the string from JTextFied to database?

can i know how to save the data from JTextFied to databse. Is it using update?

The most straightforward way would be something like:
String myKey=myKeyField.getText();
String foo=fooField.getText();
String sql="update mytable set foo='"+foo+"' where mykey='"+myKey+"'";
connection.createStatement().executeUpdate(sql);
This example assumes that the input fields cannot possibly contain quotes or the string won't be built correctly. Which by the way brings up a question I'd be interested in hearing others answer: What do you do about this? Sometimes I use PreparedStatement which handles that problem, other times I write my own little function to escape the string properly.
You can also read the record into a ResultSet and use ResultSet.update(). I'm mostly using mySql and I found that in mySql ResultSet.update just creates a SQL update statement like I did above and executes it, so the only real advantage would be if you find the syntax more convenient. Perhaps other database drivers do something different that would give other pros and cons.

How do I use a font that a user of my screen saver might not have?

I am trying to do a little experiment with fonts. I downloaded a font that was not previously installed on my computer, and am trying to make a "Hello, World!" screen saver with that font(which I installed).
The problem is that I can not even use that font. When I attempt to make a "Hello, World!" screen saver with that font, it uses the default font. Here's the code:
#import "saverView.h"
@implementation saverView
- (id)initWithFrame:(NSRect)frame isPreview:(BOOL)isPreview
self = [super initWithFrame:frame isPreview:isPreview];
if (self) {
[self setAnimationTimeInterval:1/30.0];
//either my mistake is here:
hylianFont = [NSFont fontWithName:@"Ancient Hylian - English" size:20];
attrs = [NSMutableDictionary dictionaryWithCapacity:2];
//NSForegroundColorAttributeName -- [Color green]
[attrs setValue:[NSColor greenColor] forKey: NSForegroundColorAttributeName];
// or it is here:
[attrs setValue:hylianFont forKey: NSFontAttributeName];
displayer = [[NSAttributedString alloc] initWithString:@"Hello, World!" attributes:attrs];
return self;
//... more stuff I do not use...
//simply draws "Hello, World!" in green at the top right of the screen.
//meant to draw it in the different font, but draws it in the standard font.
- (void)animateOneFrame
[displayer drawInRect:[self bounds]];
return;
@end
Where did I mistype?

I think I solved the problem. I just put the font and the screen saver in a pkg file, and make the pkg file install the font. Or I guess I could keep the font in my screen saver and test it that way. Either way, I found the answer.

How to: Save jpg frames to swf animation.

I create signatures for my friends to use in posts on forums
at the end of their messages.
Examples here:
http://s12.invisionfree.com/venvenaevici
Recently I decided to try animation, but saving in gif format
isnt allowing me to save with as much detail as I would like and
the backgrounds are comming out grainy and not smooth. After a
weeks worth of trouble shooting I think my solution is to save the
several .jpg files I have refined into a flash, but I dont know how
to do that. Can anyone help?
Also when it is saved I would like it to auto play and loop
like this gif animation I have. If only I could get it to save as
it looks on preview, or if I had proper training :/
Animation Example:
http://w3.the-kgb.com/venvenae/shalieeani.gif
Background Example without the animation of above:
http://w3.the-kgb.com/venvenae/shaliee.jpg
The program I used to get the animation frames in the first
place is called wow model viewer. Any assistance would be wonderful
and much appreciated and I would be willing to do a signature for
someone here that has helped me, if there is interst.
I wasnt sure where to post this. Im sorry if its in the wrong
place.

Plz let me know it soon .. its very urgent ..
Can I save it as Screenshot or Jpeg Image .. or how to go about it .

Sure: see below!
WARNING: this code will not compile as is because it uses some other classes from my personal code library (FileUtil & StringUtil). The particular methods of those classes which are used below are trivial methods that anyone can write, which is is why I have not posted them as well. So, to get the code below to compile, you can
a) write your own versions of these classes or
b) simply add the necessary methods to this class or
c) simply comment out their usage (in the case of StringUtil, which is just used for arg checking)
But if you still want me to post them, then I can post the relevant fragments of those classes.

import bb.io.FileUtil;

* Class which supports taking screen shots of the entire desktop, AWT Components, or Swing JComponents.
* This functionality is implemented in a series of <code>take</code> methods, each of which returns a BufferedImage.
* This class also offers convenience <code>write</code> methods for storing BufferedImages to files.
* 
* The images taken by this class should be the precise images seen on the screen.
* However, the images written to files may deviate from the originals.
* One obvious cause is limitations of the chosen file format (especially with lossy formats like jpeg).
* A subtle issue can occur, however, even when using lossless formats like png:
* if the file is subsequently opened by another application,
* that application may rescale the image, which can often cause visible artifacts.
* <blockquote>
* To see this last problem on Windows XP,
* call {@link #take()} which returns an image of the entire desktop and write it to a file,
* and then open the file with XP's default graphics file viewer ("Windows Picture And Fax Viewer").
* This program shrinks the desktop image in order to fit it inside the program's window,
* and rescaling artifacts are readily seen, especially if the desktop image has any kind of text in it.
* If "Windows Picture And Fax Viewer" instead cropped the image or had a scroll pane, then this should not happen.
* </blockquote>
* 
* Acknowledgement: this class was inspired by the program
* <a href="http://www.discoverteenergy.com/files/ScreenImage.java">ScreenImage</a>.
* Differences from the above program:
* <ol>
* <li>this class uses {@link BufferedImage#TYPE_INT_ARGB} instead of {@link BufferedImage#TYPE_INT_RGB} in order to preserve alpha</li>
* <li>this class's {@link #formatNameDefault default image file format} is PNG instead of JPEG</li>
* <li>this class's <code>take</code> methods simply take snapshots and never have the side effect of writing image files</li>
* <li>this class added a version of <code>take</code> which can get a snapshot of a region of a Component</li>
* <li>
* when taking a snapshot of a region of a Component or JComponent,
* the Rectangle that specifies the region always has coordinates relative to the origin of the item
* </li>
* </ol>

* 
* It might appear that this class is multithread safe
* because it is immutable (both its immediate state, as well as the deep state of its fields).
* However, typical Java gui code is not multithread safe, in particular, once a component has been realized
* it should only be accessed by the event dispatch thread
* (see <a href="http://java.sun.com/developer/JDCTechTips/2003/tt1208.html#1">Multithreading In Swing</a>
* and <a href="http://java.sun.com/developer/JDCTechTips/2004/tt0611.html#1">More Multithreading In Swing</a>).
* So, in order to enforce that requirement, all methods of this class which deal with components
* require the calling thread to be the event dispatch thread.
* See the javadocs of each method for its thread requirements.

 * Putting all the test code in this inner class (rather than a <code>main</code> method of the parent class) has the following benefits:
 * <ol>
 * <li>test code is cleanly separated from working code</li>
 * <li>any <code>main</code> method in the parent class is now reserved for a true program entry point</li>
 * <li>test code may be easily excluded from the shipping product by removing all the Test class files (e.g. on Windoze, delete all files that end with <code>$Test.class</code>)</li>
 * </ol>
 * Putting all the test code in this inner class (rather than a shadow external class) has the following benefits:
 * <ol>
 * <li>non-public members may be accessed</li>
 * <li>the test code lives very close to (so is easy to find) yet is distinct from the working code</li>
 * <li>there is no need to set up a test package structure</li>
 * </ol>
