16-bit string literals

How can you specify a string literal that compiles to an array of 16-bit units? "string" compiles to 1-byte char* and L"string" compiles to 4-byte wchar_t but we need a syntax to specify a string of 2-byte unsigned short.

I'm reasonably confident that there is no 16-bit driver that works with an 8i client. I'd suspect that the old 16-bit drivers can probably be used to connect to an 8i database from an older client.

Create an image from a bit String

Hi everybody
I don't know if this is the correct forum for this so first of all sorry if I did it wrong. I have never created an image in Java so I am a little bit lost with my new task.
I have a bit String (for example "00111010") and I want to create an image converting the 0-s into white pixels and 1-s into black ones. The new image should be 8x1 pixels (for the previous example would be white-white-black-black-black-white-black-white).
As I have explained before, I have never done something similar so I don't know how easy is my problem to resolve. Any help?

read up on Java2D and image processing
try some tutorials
basically you need to convert your data to an intensity map
there's a couple ways to do it
i'd convert to a byte or int array which you can pass into the image constructors
try and get started then come back here when/if you have specific problems

Error SQL70015: Error validating element [dbo].[GetDocument]: Deprecated feature 'String literals as column aliases' is not supported

Using MS SQL Management Studio 2012 attempting to export (from GoDaddy) a .bacpac database for import to Azure and get the error message listed in the Title (String literals as column aliases is not supported on SQL Azure). There was a discussion of this
problem in mid-2013, but it ended with saying that this was a bug with Azure validation, but had been fixed and did not require rewriting of databases. Anyone with a clue how to successfully export/import around this?

Hello,
A string enclosed in quotation marks used as a column alias for an expression in a SELECT list is not support in Windows Azure SQL database. Please use "expression [AS] column_alias" instead of " 'string_alias' = expression ".
In your case, you can try to create an application with in SSDT and use Schema Compare to filter out and fixed incompatible objects, and then deploy the database to Windows Azure SQL database.

Small clarification in String literals

Hi
System.out.print((hello == ("Hel"+"lo")) + " "); Returns "TRUE"
Reason:Strings computed by constant expressions compile time and then treated as if they were literals.
Is it true?String Literal memory allocation at compile time or runtime?
Thanks

Works differently if any part of the concatenation is a variable.Can you explain this in more detail or provide some more pointers?If any part of what's being concatenated is not a compile-time constant, then rather than producing a single literal that goes into the pool, the compiler produces code to execute at runtime that builds up the string using StringBuilder.append or StriingBuffer.append of some combination of runtime expressions and String literals, depending on what the specific pieces are. You can use javap to see the generated bytecode.

Bit-String to Hex

Hello
I've got following question: I have a STRING of bits e.g. "01001010". Is there any function to convert it to Hex - code?

See the attached code. I wasn't sure by what you meant by a "STRING of bits" so it shows two different things.
Remember also that the distinctions between binary, decimal and hex are only significant to human beings reading the numbers--computers don't really care. An unsigned 8-bit value is an unsigned 8-bit value, regardless of how it's represented for human consumption.
Note that in a array the LSB is the first element. In a string, the LSB is the far right-hand digit.

Char to bit string???

Hi everyone,
I have a small problem and I was wondering if anyone can help. I want to convert a char value to a string of bits. I have had no problem doing it with an integer but I "keep reaching for the Aspirin" when it comes to the char. Any ideas? I am sure I am doing something stupid - it should be relatively simple.

Here's the general idea:private static String toBitString(char c) {
return Integer.toBinaryString(c);
private static String toFixedLengthBitString(char c) {
return Integer.toBinaryString(c | 0x10000).substring(1);
}

How does Java Handle String Literals Setting to Null for Identical Values ?

Suppose,
String s1="Java";
String s2="Java";
Now if i am not wrong only one value(bit pattern) "Java" exists in the heap and both s1 and s2 are pointing to it.
If i set s1 to null,
s1=null;
Won't s2 be affected (it is not getting affected actually..)
What could be the cause for this ?
Thanks in Advance.

No. In your model here, a variable's value is a String object. It's as if your entire house exists on my s1 paper, and an exact duplicate house with all the same contents exists on my s2 paper. In Java, no variable or expression ever holds an object. No value is ever an object.
It's more like this:
Variable         Memory Address         Value
s1                      0234234           11223344
s2                      0234235           11223344
is s1 is set to null :
Variable         Memory Address         Value
s1                      0234234           null
s2                      0234235           11223344and 11223344 is, roughly speaking, the "address" where the String object holding "Java" is stored.
And in both your model and mine, "Memory Address" is not the address that the variable holds. Rather, it is the address that corresponds to what we humans have named s1 and s2 for our convenience.

SPARQL query through Jena adaptor not work when string literals used

Hi,
When I executed the following SPARQL query through Oracle Jena adaptor:
SELECT ?personHasFirstName WHERE
{?personHasFirstName foaf:firstName ?name . }
I got the expected results.
However it won't return anything when I narrowed the query to match a particular name like below:
SELECT ?personHasFirstName WHERE
{?personHasFirstName foaf:firstName \"Julie\" . }
I also tried the Filter approach:
SELECT ?personHasFirstName WHERE {?personHasFirstName foaf:firstName ?name . FILTER (?name =\"Julie\") }
It still doesn't return any results.
I saw from the release notes about the bug dealing with "\". My guess is that the above behavior is caused by that bug. What is the suggested way to walk-around this? Thanks,
Weihua

Could you please try this? It works as expected on my machine.
GraphOracleSem graph = new GraphOracleSem( oracle, modelName);
ModelOracleSem model = new ModelOracleSem(graph);
Node sub = Node.createURI("http://test.com/employee123");
Node pre = Node.createURI("http://xmlns.com/foaf/0.1/firstName");
Node obj = Node.createLiteral("Julie");
graph.add(Triple.create(sub, pre, obj));
String queryString =
" PREFIX foaf: <http://xmlns.com/foaf/0.1/> " +
"SELECT ?person WHERE { ?person foaf:firstName \"Julie\" . } ";
QueryExecution qexec = QueryExecutionFactory.create(
QueryFactory.create(queryString), model);
try {
ResultSet results = qexec.execSelect();
while (results.hasNext()) {
QuerySolution soln = results.nextSolution();
psOut.println("runQuery: soln " + soln);
finally {
if (qexec != null)
qexec.close();
output snippet:
runQuery: soln ( ?person = <http://test.com/employee123> )

Unicode in string literals

Hi,
Some unicode characters are refusing to be 'escaped' when placed into a string literal.
For example, "\u1fff" results in the 5 char long string "u1fff" - the backslash is stripped and that's it.
There appear to be many other characters that also behave like this.
Anyone know what's up with this? Are such chars illegal or something?
Is there any list of these chars?
Bye!
Mark

I don't think Unicode 1FFF exists (it's blank). For example 1FF2 does exist and works fine:
textfield.text = "\u1ff2";
// you get ῲ

String literals in Actionscript missing characters?

I'm putting together a gallery/info viewer in Flash for a fraternity I'm in. What I have it doing is:
-A thumbnail of each member's picture is visible
-When the thumbnail is clicked, a picture is called into a UILoader at the top of the screen, and a string is called to be placed into a dynamic textbox next to the UILoader.
Here's the code for my thumbnail...
(currentData.currentPic is the location for the UILoader)
myLastName.addEventListener(MouseEvent.CLICK, myLastNameLoad);
function myLastNameLoad(e:Event){
currentData.currentPic.source = "../NewSinfonia/myLastName.jpg";
infoText.text = "First Last \n Initiated Fall 10 \n Saxophone Performance '13 \n Webmaster";
And here's what I get when I click on the thumbnail in the movie preview or when I open it in HTML in Firefox:
First Last
nitiated Fall
Saxophone Performance
Webmaster
So, random characters are missing, and the same characters (by which I mean the I in Initiated, both years, etc., not the 10th character or whatever) are missing throughout all forty-or-so thumbnails. Everything else (picture loading, etc.) is working fine. I'm working out of "the official training workbook from Adobe Systems" for guidance, and the example they had similar to this involved pulling .txt files to load into the box, which I can do if I need to, but I'd rather just keep it this way. Anyone have any ideas? All help is appreciated.

Single quote you have to put at the begining and the end of a string.

Searching for String literals in a ResultSet

Hi! I am currently working in a little project in which one functionallity should be the possibility to search for customers over a special dialog. This dialog consists of a JTextField and a JTable. Now when the user enters e.g. 'a' in the textfield all the customers which include an 'a' at the beginning of their name should be displayed in the JTable. When the user enters a 'b' addtionally all users which fit the condition 'ab' are shown. Currently I requery the DB every time a key is pressed. But this is not very performant over the network. Is there a way to store a buffered ResultSet in RAM and make queries on this ResultSet?
Thx

...but there must be a easier way to deal with it!Either you have all the data in the GUI or you don't. If you have it there then you have to get all of it. And then do something with it. If you don't get it all, then you are going to have to do a query each time. There is no other solution.
You could do a partial solution, for example do the first query after they type the first letter and then after that handle the data yourself.
(Keep in mind that this sort of GUI is 'really cool' but generally serves no pratical purpose particularily for large businesses. Day to day work doesn't support such usage.)

PDF String literal Parsing Issue

I have the following contents in the same PDF page, in different ObjectX:
link to original file
First:
    [(some text)] TJ ET Q
    [(some other text)] TJ ET Q
Very simple and basic so far...
**The second**:
    [( H T M L   E x a m p l e)] TJ ET Q
    [( S o m e   s p e c i a l   c h a r a c t e r s :   <   ¬   ¬   ¬   &   ט   ט   ©   >   \\ s l a s h   \\ \\ d o u b l e - s l a s h   \\ \\ \\ t r i p l e - s l a s h )] TJ ET Q
NOTE: It is not noticeable in text above, but:
'H T M L   E x a m p l e' is actually 0H0T0M0L0[32]0E0x0a0m0p0l0e where each 0 is a literal value 0 == ((char)0) so if I ignore all the 0 values, this actually turns to be like the upper example...
Some Bytes:
    htmlexample == [0, 72, 0, 84, 0, 77, 0, 76, 0, 32, 0, 69, 0, 120, 0, 97, 0, 109, 0, 112, 0, 108, 0, 101]
    <content> == [0, 32, 32, -84, 0, 32, 32, -84, 0, 32, 32, -84, 0, 32, 0, 38, 0, 32, 0, -24, 0, 32, 0, -24, 0, 32, 0, -87, 0, 32, 0]
But in the next line I need to combine every two bytes into a char because of the following:
<   ¬   ¬   ¬...> is actually <0[32][32]¬0[32][32]¬0[32][32]¬...> where the combination of [32]¬ is €

                'Length' : 10200.0f
            } + Stream(131072 bytes)
        'Type' : "Font"
There is no indication to the encoding type of the font.
As for the ToUnicode object, in the case of these font it is an unnecessary it should have been Identity-H but instead it is an X == X mapping here are some examples that goes from until FFFF:
    <0000> <00ff> <0000>
    <0100> <01ff> <0100>
    <0200> <02ff> <0200>
    <0300> <03ff> <0300>
    <0400> <04ff> <0400>
    <0500> <05ff> <0500>
    <0600> <06ff> <0600>
    <0700> <07ff> <0700>
    <0800> <08ff> <0800>
    <0900> <09ff> <0900>
    <0a00> <0aff> <0a00>
    <0b00> <0bff> <0b00>
    <0c00> <0cff> <0c00>
    <0d00> <0dff> <0d00>
    <0e00> <0eff> <0e00>
    <0f00> <0fff> <0f00>
    <1000> <10ff> <1000>
    <1100> <11ff> <1100>
    <fc00> <fcff> <fc00>
    <fd00> <fdff> <fd00>
    <fe00> <feff> <fe00>
    <ff00> <ffff> <ff00>
So the mapping is not in the ToUnicode object, but still other renderers can render it well!
The problem I'm facing is not the conversion itself I use the following and this works well for the F4(see below) string literals, but mess up all the other strings in the page.
   new String(sb.toString().getBytes("UTF-8"),"UTF-16BE")
The problem is to know when to read the bytes as UTF-8 or any other encoding, where does the parameters for the String Literal reside?

I have read your post multiple times, and am still trying to make complete sense of it, in terms of what you're trying to accomplish. I think that you are approaching the problem in the wrong way, and my instincts tell me that you're trying to fabricate input data for what you see encapsulated in the PDF in terms of data structures. The specifying of null (0x00) bytes in the input data is what is leading me to this conclusion.
Keep in mind that the sole purpose of the Identity-H encoding (which is also instantiated as a CMap resource) is to map GIDs to their hexadecimal equivalent, which can look a lot like a 16-bit Unicode value because a GID is represented using 16 bits. The ToUnicode object can be an entirely different beast, because it maps GIDs to genuine Unicode values.
