Converting String to RGB or hex

I've got string
"C0C0C0"
which is grey color, and I have to convert it to int:
0xC0C0C0
is that possible in J2ME?

There's no such constructor in MIDP. You'll have to use
int hexInt = Integer.parseInt("C0C0C0", 16);
yeah thats right. i kinda wrote that in a hurry

Problem in Converting String (containing arabic) to HEX

Hi,
I am trying to convert Arabic Text stored in a String into HEX format.
The arabic range in unicode is: 0600�06FF
But when i convert using Integer.toHexString(), i get hex values which are not in the above range.
Here goes the code:
for(int i=0;i<text1.length();i++)
if((int)text1.charAt(i)<10) {
hextext+="0"+Integer.toHexString(text1.charAt(i)).toUpperCase();
else {
hextext+=Integer.toHexString(text1.charAt(i)).toUpperCase();

Converting byte from dec to hex

Hi All,
I'm having a problem converting byte from decimal to hex - i need the following result:
if entered 127 (dec), the output should be 7f (hex).
The following method fails, of course because of NumberFormatException.
    private byte toHexByte(byte signedByte)
        int unsignedByte = signedByte;
        unsignedByte &= 0xff;
        String hexString = Integer.toHexString(unsignedByte);
        BigInteger bigInteger = new BigInteger(hexString);
        //byte hexByte = Byte.parseByte(hexString);
        return bigInteger.byteValue();
    }

get numberformatexception because a lot of hex digits cannot be transformed into int just like that (ie f is not a digit in decimal) heres some code that i used for a pdp11 assembler IDE... but this is for 16-bit 2s complement in binary/octal/decimal/hex , might be useful for reference as example though
    public static String getBase(short i, int base){
        String res = (i>=0)? Integer.toString((int)i,base)
                : Integer.toString((int)65536+i,base) + " ("+Integer.toString((int)i,base)+")";
       StringBuffer pad= new StringBuffer();
        for(int x = 0; x < 16 - res.length() ; x++){
            pad.append("0");
        res = pad.toString() + res;
        return res;
    }

Checking and Converting binary, octal, decimal, and hex

Hi,
I have a classroom project which will need to validate that data entered in a text is of a certain type with a keyListener, and then convert that value to the other 3 types.
I know character.isDigit will handle the decimal case, and that I can then use Integer.otString methods to convert to binary, octal, and hex, but what about the other cases?
Thanks

OK, this isn't working. If I've already established
that the string entered into, for example, the
integer-only textfield is a valid integer, I should be
able to simply use integer.parseint(s, 2) to convert
it into binary, right?Not exactly. You should be able to use Integer.parseInt(s, 2) to return the result of converting it from binary representation. You appear to think that this affects whatever "s" refers to, which is not the case. Note also, that method returns an int which is the decimal value in question.
When you are thinking of int variables, be careful not to think of them as "decimal" or "binary". They are neither. They are just numbers. "Decimal" and "binary" are text representations of numbers, so those concepts can only be applied to strings.
Integer.parseInt(s, 2);
txtBin.setText(s);So here you want to assume that the input is a string that represents a number in decimal, and you want to find the string that represents the number in binary. Like this:// convert string in decimal representation to number
int dec = Integer.parseInt(s);
// convert int to binary representation as string:
String binary = Integer.toBinaryString(dec);
// write that to the text field
txtBin.setText(binary);You could use a one-liner to do that, but you'll need the "dec" variable to set the other text boxes.

Convert FF Ascii To FF Hex

I have a serial device that returns a hex number but in ascii format(!).
For example:
Instead of returning FF0A (viewed in a string indicator set to Hex display), it returns ff0a (as viewed in a string indicator set to normal display). But the data actually represents FF 0A.
My question is how can I convert ff0a (ascii) to FF 0A (hex)?
Thanks in advance!
Solved!

Not able to convert string attribute to number and date please help me out

not able to convert string attribute to number and date attribute. While using string to date conversion it shows result as failure.As I am reading from a text file. please help me out

Hi,
You need to provide an example value that's failing and the date formats in the reference data you're using. It's more than likely you don't have the correct format in your ref data.

How can I convert Pdf from RGB to CMYK, keeping font color 100% K while working in Illustrator?

How can I convert Pdf from RGB to CMYK, keeping font color 100% K while working in Illustrator?
When I try to open the document in Illustrator and I convert to CMYK the black font converts to rich black, but to set up for Offset printintg I need the text to be only in Black (100%K).
The original source of the document is a Microsoft Word file, I have converted the Word file to Pdf in order to setup for OFfset Printing.
Thanks

I have tried that way, but the downside is that the fonts are set in gray not in a 100%K, also I have to deal with other fonts that are composites and meant to stay Full Color. I could select text by text and convert to gray but, its a 64 page document and I wouldn't want to make a expensive mistake.

Convert String to Date and Format the Date Expression in SSRS

Hi,
I have a parameter used to select a month and year string that looks like:    jun-2013
I can convert it to a date, but what I want to do is, when a user selects a particular month-year  (let's say "jun-2013")
I populate one text box with the date the user selected , and (the challenge Im having is) I want to populate a text box next to the first text box with the month-year 2 months ahead.    So if the user selects
jun-2013   textbox A will show jun-2013
and textbox B will show aug-2013..
I have tried:
=Format(Format(CDate(Parameters!month.Value ),
"MM-YYYY" )+ 2 )   -- But this gives an error
This returns the month in number format   like "8"    for august...
=Format(Format(CDate(Parameters!month.Value ),
"MM" )+ 2 )
What is the proper syntax to give me the result    in this format = "aug-2013" ???
Thanks in advance.

You can convert a string that represents a date to a date object using the util.scand JavaScript method, and then format a date object to a string representation using the util.printd method. For more information, see:
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1254.html
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1251.html
In your case, the code would be something like:
var sDate = "2013-01-10";
// Convert string to date
var oDate = util.scand("yyyy-mm-dd", sDate);
// Convert date to new string
var sDate2 = util.printd("mm/dd/yyyy", oDate);
// Set a field value
getField("date2").value = sDate2;
The exact code you'd use depends on where you place the script and where you're getting the original date string, but this should get you started.

Convert String variable value to an Object referece type

Hi all,
I want to know that if there any possible way to convert String variable value to a Object reference type in java. I'll explain by example if this is not clear.
Let's think that there is a string variable name like,
String name="HelloWorld";
and there is a class name same to the variable value.
class HelloWorld
I am passing this string variable value to a method which is going to make a object of helloworld;
new convertobj().convert("HelloWorld");
class convertobj{
public void convert(String name){
// in hert it is going to create the object of HelloWorld;
// HelloWorld hello=new HelloWorld(); just like this.
now i want to do this from the name variable value.( name na=new name()) like wise.
please let me know if there any possible way to do that.
I am just passing the name of class by string variable then i wanted to make a instance of the class which come through the variable value.
thanx.

Either cast the object to a HelloWorld or use the reflection API (Google it) - with the reflection API you can discover what methods are available.
Note: if you are planning to pass in various string arguments and instantiate a class which you expect to have a certain method... you should define an interface and have all of your classes that you will call in this way implement the interface (that way you're sure the class has a method of that name). You can then just cast the object to the interface type and call the method.

Once you have a java.util.Date you can convert it to oracle.jbo.domain.Date. (see http://www.fifkredit.com/bc4jdoc/rt/oracle/jbo/domain/Date.html)

How to convert CMYK to RGB programmatically.

Hi,
I have a CMYK colorspace in indesign, i want to convert that as RGB color space, I got some codes, but I am getting incorrect data.
Some of the codes which I tried are given below
        double cyan = 35.0;
        double magenta = 29.0;
        double yellow = 0.0;
        double black = 16.0;
        cyan = Math.min(255, cyan + black); //black is from K
        magenta = Math.min(255, magenta + black);
        yellow = Math.min(255, yellow + black);
        l_res[0] = 255 - cyan;
        l_res[1] = 255 - magenta;
        l_res[2] = 255 - yellow;
@Override
    public float[] toRGB(float[] p_colorvalue) {
        float[] l_res = {0,0,0};
        if (p_colorvalue.length >= 4)
            float l_black = (float)1.0 - p_colorvalue[3];
            l_res[0] = l_black * ((float)1.0 - p_colorvalue[0]);
            l_res[1] = l_black * ((float)1.0 - p_colorvalue[1]);
            l_res[2] = l_black * ((float)1.0 - p_colorvalue[2]);
        return (l_res);
The values are C=35, M = 29, Y = 0, K = 16 in CMYK color space and the correct RGB values are R = 142, G = 148, B = 186.
In adobe indesign, using swatches we can change the mode to CMYK or to RGB.
But I want to do that programmatically, Can I get any algorithm to convert CMYK to RGB which will give the correct RGB values.
And one more question, if the alpha value for RGB is 1 then what will be the alpha value for CMYK?
Can anyone help me to solve these issues... Thanks in advance.

All you have to do is loop thru the swatches and change the space to RGB. Below is an AppleScript, but it shouldn't be too difficult to come up with the equivalent JavaScript. Your document's assigned RGB space will determine what RGB space the CMYK converts to, so if you are looking for sRGB, then Edit>Assign Profiles...>Assign Profile: sRGB
tell application "Adobe InDesign CS3"
tell document 1
repeat with a from 1 to count of every swatch
try
set space of color a to RGB
end try
end repeat
display dialog "All swatches have been converted to RGB color"
end tell
end tell
