Thanks kindly,

Dear Ulf,

I tried to store the image in the internal memory. But,
Intent takepicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); takepicture.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
This doesn't allows me to store the image in the internal memory.

please give any suggestions to store the image in internal memory or sqlite.

Also my camera activity crashes after clicking OK, why is it so?

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch (requestCode) { case TAKE_PICTURE_ACTION_CODE: switch(resultCode){ case RESULT_OK: handleCameraPicture(); break; case RESULT_CANCELED: Toast.makeText(ListMediaTypes.this, "canceled,pls try again", Toast.LENGTH_SHORT).show(); break; default: Toast.makeText(ListMediaTypes.this, "canceled,pls try again", Toast.LENGTH_SHORT).show(); break; } break; } }

Thanks kindly,

Thanks Ulf,

Yes, i should not keep the image in the sd card.

Just asking for my curiosity, is it possible to make the image write protected by using any classes in android api?

Dear All,
In my project i want to capture an image.(i done this)
That captured image should be uploaded to the server(i will do it)
But the problem is- the image which has taken only uploaded to the server.

Now, how can i check this condition?

If the user replaced the original captured image with the same name then i cannot accomplish what i need to.

Please correct me, if i'm wrong.
1) storing the image in the internal memory
2) storing the image in the sqlite using blob
(in both cases after uploading ,the images should be deleted)

If i store the image in the sd card, is it possible to write protected the image ?

Thanks kindly,

Dear All,

I want to develop a web app for an educational institution. I've experience in Servlet,JSP, JDBC,Ajax etc.
But I am afraid of CSS - cascading style sheet since i couldn't manage the layout to run on different browsers.

Kindly give me some idea to develop the app in any CMS that support Java.

Hi,

I found that characters '\u000D' - int value 13 and '\U000A'- int value 10(for '\n') were appended to the array of characters.

i.e., JavaRanch\u000D\U000A ,

so that i get 11.

What is the character value for \u000D? i get NewLine. is that True?

Hi,

InputStreamReader isr=new InputStreamReader(System.in); char [] a; a=new char[100]; int count=0; while((count=isr.read(a,0,a.length))!=-1){ System.out.println(count); }

Input: JavaRanch // 9 + 1(for '\n')
But Output: 11


1> What is the 11th character? or is there any '\0' character?
2> Whether the read() used here, read characters from the keyboard BUFFER until NewLine Character is given ?

Well, yeah, you don't have to define a CLASSPATH variable, but that is not specific to Java 7. Even older versions of Java allowed usage without the CLASSPATH environment variable assigned. If you don't have the environment variable assigned, you can set its value as parameters to the java and javac commands. And if you don't want to do that, you can always locate your files so that it will work -- since the default is to have the current directory as the classpath.

Hi Henry,

/* Sum.java: */ package com.anand.sample; public class Sum{ public Sum(){ System.out.println("Hello world"); } } /* Test.java */ package com.anand.mytest; import com.anand.sample.Sum; public class Test{ public static void main(String[] args){ new Sum(); } }

Compiled: project/src/$ javac -d ../build Sum.java //successfully compiled

project/src/$ export CLASSPATH=/home/project/build;

project/src/$ javac -d ../build Test.java //successfully compiled

But, I cant run the Test class. why it so?

I have got the error: java.lang.NoClassDefFoundError. Test


please help me how to run this program...

Hi Friends,
I can't able to declare typedef in the union,say,

union xyz{
typedef struct bio{
char name[100];
int age;
float salary;
}b;
char a[sizeof(struct bio)];

};

it works well if i remove typedef keyword.

why is it so?

Hi Friends,

Is it possible to launch my own application automatically after the OS booted?

If it so, then how?

ObjectInputStream Javadoc wrote:
Any attempt to read object data which exceeds the boundaries of the custom data written by the corresponding writeObject method will cause an OptionalDataException to be thrown with an eof field value of true. Non-object reads which exceed the end of the allotted data will reflect the end of data in the same way that they would indicate the end of the stream: bytewise reads will return -1 as the byte read or number of bytes read, and primitive reads will throw EOFExceptions.

My bet is that the the getMessage() call in your catch block returns null. Try adding ex.printStackTrace(); to the catch block to find out.

Hi,

Can you alter the code to read the exact two object without any exception?


Kindly help me..

Hi,

why do i get null message in the following code?
import java.io.Serializable; public class Student implements Serializable{ private String name; private int age; public Student(String name,int age) { this.name=name; this.age=age; } @Override public String toString() { return "Student{" + "name=" + name + ", age=" + age + '}'; } } ------------------------------------------------------------------------------------------------------------------------- package usingobjectstreams; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; public class UsingObjectStreams { public static void main(String[] args) { Student s1,s2; s1=new Student("anand", 25); s2=new Student("damodaran", 20); try { ObjectOutputStream out=new ObjectOutputStream(new FileOutputStream("bio.txt")); out.writeObject(s1); out.writeObject(s2); } catch (IOException ex) { System.out.println(ex); } try { ObjectInputStream in=new ObjectInputStream(new FileInputStream("bio.txt")); Object ob=null; while((ob=in.readObject())!=null){ System.out.println(ob); } } catch (Exception ex) { System.out.println(ex.getMessage()); } } }
Output:

Student{name=damodaran, age=20}
null
