Hi

I am trying to display the below information using JOptionepane.showMessageDialog();

=======================================================
Scroll exit swirl velocity factor = 1.1000
Impeller friction loss factor = 5.0000
Impeller incidence loss factor = 1.0000
Impeller pressure loss factor = 0.0300
Bearing loss factor = 1.7500
=======================================================
But when I display it using JOptionapane.showMessageDialog() it shows like this,
=======================================================
Scroll exit swirl velocity factor = 1.1000
Impeller friction loss factor = 5.0000
Impeller incidence loss factor = 1.0000
Impeller pressure loss factor = 0.0300
Bearing loss factor = 1.7500
=======================================================

why it is removing the spaces??
Is there any way to tell Joptionpane not to remove the spapces in message displayed??

Please help me out.

Sorry even this site is removing the spaces that I intended to show you guys in the previous message.

Same thing is happening in JOptionpane..

Try wrapping it inside HTML so you can control the spaces and formatting.

How to wrap it properly?

It is showing like this: "<html><body>contents here</body></html>"

It is showing the tags too.
Please suggest how to go about.

Thanks in advance.

JOptionPane.showXXX accepts Objects as messages.
Since JLabel supports HTML, you can construct a JLabel with your HTML formatted message and then pass this label to the JOptionPane.

Thanks for your suggestions.

I tried creating a JLabel instance with "<html><body>contents here</body></html>" and passing it to JOptionpane.showMessageDialog().

Even though it is same thing is happening.

Here is my code:
===================================================================
File outFile = new File(outFileNameWithoutExt+".OUT");
read = new FileReader(outFile);
buffRead = new BufferedReader(read);
//read first line from .OUT file
String str = buffRead.readLine().trim();

//read and discard .OUT file data until we find "CALCULATED GEOMETRY"
while(!str.equalsIgnoreCase("CALCULATED GEOMETRY"))
{
//read the subsequent line from .OUT file
str = buffRead.readLine().trim();
}
//read and discard the empty line
buffRead.readLine();
StringBuffer calculatedGeometry = new StringBuffer();
//read first line in calculated geometry info
str = buffRead.readLine();
//read until we find an empty line
while(!str.isEmpty())
{
//append the calculated geometry info and new line character
calculatedGeometry.append(str+"<br>");
//read next line
str = buffRead.readLine();
}

//display the calculated geometry info
JLabel jbl = new JLabel("<html><body>"+"CALCULATED GEOMETRY :<br><br>"+calculatedGeometry.toString()+"</body></html>");

JOptionPane.showMessageDialog(null, jbl , "Calculated Geometry Information", JOptionPane.PLAIN_MESSAGE);

===================================================================

Am I doing anything wrong in my code??

Works fine for me.
Try posting the text with lines but use the CODE tags. That might preserve the spaces you are mentioning.

Well you can try posting the text you want to display. Just replace all spaces with say '$'

This is the message to be displayed:
==========================================================
Impeller inlet annulus area$$$$$$$$$=$$$$2728.87 sq mm
Impeller exit annulus area$$$$$$$$$$=$$$$2987.36 sq mm

rms diameter at impeller exit$$$$$$$=$$$$50.505 mm
Exhaust duct exit annulus area$$$$$$=$$$$4047.79 sq mm

==========================================================

I have replaced white space by '$' symbol.

I want to retain those spaces in the message when I print it using JOptionpane.showMessageDialog()

The 'symbol' for 'space' in HTML is ' ' (with the semi colon)
Just replace '$' with ' ' to get it working.

EDIT> (& n b s p

It got converted to a white space DOH! Just remove the spaces between & n b s p ; and use it. The ';' is required

EDIT AGAIN: Admins help.Is there anyway I can switch off HTML>?

No just for showing the exact message with spaces, replaced those spaces by $ symbol.

I did not understand what to suggested me in your previous post.
