}while(tryAgain = true);
The above code will always set tryAgain to true; you should be using the logical == operator.

I'm new on this site but i know Core Java And Adv. Java very well.. So here is solution to u r problem if u have not got it yet.
First use assigment operator == in while loop
In your code loop will keep executing till the value of tryAgain is true . if u want loop to stop right after correct value of username and password u need to make tryAgain false in first if block and make tryAgain true in second if block. it will work properly

I've got a web app I'm working on that allows users to view conference rooms and reserve rooms for certain days/times. We are wanting to add a "calendar" link that the user can click on for an event that is scheduled and add that event to their Outlook or G-mail calendar. That's not the tricky part. The tricky part is if an event is modified in any way (time changed, cancelled, location changed, etc) everyone who has "subscribed" to that event in their calendar should have their calendar event automatically updated. The guy who started coding this web app kept telling everybody he was going to use iCal. Unfortunately, he's not around anymore for me to ask questions of and he never actually started coding anything for this even though he told people he was almost done with it. I've looked at iCal and from what I can tell it is a Windows-based calendar server with a web front end. We are a Linux/java shop and I need something that has a web service to interface with from my java web app. Has anybody done something like this and have any recommendations?
Don't blame me. I voted for Chuck Norris.

Hello all member,
Please help me to convert images to unsigned char of array 2d data type by java code.
Ex: We have a file Test.png so I want to convert this file to unsigned char Test[][48]={{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,},
{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xF0,0x03,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,}};
Thank you.

You need to explain in more detail what you mean. A file is simply a stream of bytes, so what exactly is your problem?

Hello,
I have a image file. (Test.png) I need algorithms convert this image to unsigned char Test[][]={{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,},
{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xF0,0x03,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,}};
Formatting that.
Thank you for reply me!

Sorry but I still do not understand what you mean by 'convert'. A file (as I said previously) is merely a stream of bytes, so reading it into memory you automatically have an array. What exactly are you trying to do with this file's content?

Hi,
I have one file test.png I want to convert to array 2d of hexadecimal.
Ex: test.png ---Convert----> unsigned char test [][]={{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,},
{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xF0,0x03,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,}};
for Example,
Thank you for helping me..!

That is the third time you have posted exactly the same information which gives no explanation of what you mean by "convert". As I said before, if you read the file into memory it will be in an array of bytes, so what do you want to convert it to?
Use the best guess

|

|

Oh..!
For example: I have Test.bmp I want to convert it to hexadecimal of array 2d.
|
|
|
|

There is little point in you continuing to repeat the same sentence which makes no sense. I cannot repeat enough that a file (any file) is a 1-dimensional array of bytes, so what exactly are you trying to convert it into, and how do you expect to make it 2-dimensional?
Use the best guess

Do you mean you don't know what you want to do? In that case, what was the point of this thread?

Please try doing a bit of research before posting questions like this. If you have a specific problem then show what you have done and what errors you receive. But don't assume that we can guess what is happening in your program.

|
|
|
|
k first i would like to say sorry to u for d't get any research with those questions..afterwards i will post recent questions...

Keep it to the POI API. That is working, although it is still under construction.
You can find some examples in the Unit Tests of POI-HWPF[^].
