I can't use Math.class
I can't use Math.class although I import java.lang.*.
plz help me.
and tell us what you mean by "can't use"My father began to work a PC as he was already
retired. He has been fighting with it ever since.
Sometimes he calls me for help crying "everthying has
disappeared!"
I ask him: "What is 'everything' and what does it
mean 'disappeared'?"you could then go on to throw a further spanner in the works by asking what "has" means :)

Can any help, can i use java class in
froms 6 or any one have designed form
of progress bar please help meThanks for your reply...
Actually the task is quite simple... It requires me to do a better interface for a tomcat server folders...
For example, users are free to access
http://apache.oss.eznetsols.org/jakarta/tomcat-5/v5.0.12-beta/
to download the tomcat... However, its index may not nice and easy for browing.. Therefore, the task requires a new dynamic page to access this server folder, and get all file names under this folder, anlaysis whether it is file or directory..and finally get its path....
It is quite easy to do a JSP page, but I don't know whether it is possible to do by using JavaScript .... Although JS is running in client side, the user/client also can access the tomcat folder, why not JavaScript?
Thanks a lot!

Can I use Flash classes in Flex?
Hello,
I need to know if all the flash classes can work in Flex,
since some Actionscript which use flash classes works as expected
in flash but NOT in Flex, so I need to understand or know which do
works and which does not?
..and thanks for any response :)
Regards,
Jamalit is possible to import any UIComponent made in FLASH CS3 or
even previous versions into Actionscript and use them. The process
is more complex though.
I'll try to explain:
First make sure that when you created the UIComponent it
actually exists as a class with in the flash movie, this is give it
a LINKAGE NAME.
Second compile this SWF or SWC and put it in the path of your
flex Proyect.
Third use de [EMBED] compiler command to include this class
into your AS class, the way to do it is this:
[Embed (source="/assets/UICOMPONENT.swf")]
[Binddable]
private var UI:Class;
Once you do that you can use the class each time you want:
var tmp:MopvieClip= new UI();
if You don't want to load the hole movie, you can add
elements of it, just read the documentation on the EMBED Command.
One thing I've used though is to clone child element's of the movie
and use them in my class later.
Some tips I've found out:
1.- The object created is a MovieClip whith one Child Element
that's a Loader class.
2.- You have to implement a Listener to make sure the Embed
element is loaded before use it or you'll get an error.
3.- You'll then be able to access all the elements in the
movieclip created with Flash CS 3 or 2.
4.- I've noticed that there are some compiling isues when
using filters in button frames, I've only used the CS2 Actionscript
preview and not CS3 so I don't know if this was solved. -
Can I use any Class in a Use Bean Tag of a JSP
I have tried to modify the existing EditForm.java file and created a new Class File which changes the presentation(render method)in the Edit Form.
can I use the new class as a Bean in the use bean tag of a JSP.You can use any class as part of the useBean tag. If you want to add your class to the list of available webbeans, you can add it to <jdev dir>\teamplates\webbeans.xml.

OpenerLink - url ends with ampersand. can't use style class...
hello. i am using openerLink to link to communities. i also want to apply a style class to the link text. however the url that is generated ends with an ampersand. consequently, it ignores the style class. the href is shown below.
href="http://hera:8080/portal/server.pt?space=Opener&control=OpenObject&cached=true&parentname=Gateway&parentid=None&in_hi_ClassID=512&in_hi_userid=2&in_hi_ObjectID=209&in_hi_OpenerMode=2&" class="bulletTextLink2" border="0"
when i remove the ampersand, it works perfectly (it uses the style).
what is the solution? obviously i don't have direct control over the generation of the href. can i append something to the url so that it doesn't end in an ampersand?
thanks
chrisThe message above was posted by me two years ago and was brought to my attention today. Here's a short update: The network team added a load balancer mdaoid in front of, and resolved to, mdaoid1 and mdaoid2 (in round-robin fashion). The problem described in this thread is bypassed because the JDBC URL can simply use one-OID format, in which mdaoid is used as the LDAP server.

How can I use a class in an application
here are my instructions, my professor confuses me like crazy, so I'm thinking this is a basic question:
Input Requirements
Ask the user to enter the value of the radius. You may assume that the user will enter a positive value for the radius. Your program should display the instructions for using the program and a prompt for the radius as illustrated in the sample run shown above.
Miscellaneous Requirements
Using Windows Explorer, copy your Circle.java file from your Lab04 project folder into your Hmwk04 project folder. This makes the Circle class available to your application. Your application should use a Circle object to store the radius entered by the user. Your application should get the specified output values (radius, diameter, circumference, and area) from this Circle object.
I have the Circle.java thing in my folder, (we use blue j) so it is useable, but I really do not know what to do. The Circle object has the information about the area and stuff
ex)
public double getDiameter ()
return 2.0* radius ;
public double getCircumference ()
return 2.0*Math.PI*radius;
etc and stuff, but I really do not know how to bring that thing over to use it,
this is what I have so far and this is right, I just do not know where to go from here.
public static void main(String[] args) throws Exception
double radius;
Circle myCircle = new Circle();
Scanner dl = new Scanner(System.in);
System.out.println("Given the radius of a circle, this program");
System.out.println("finds the diameter, the circumference and the area");
System.out.println(" ");
System.out.println(" ");
System.out.println("Please enter the Radius: ");
radius = dl.nextDouble();so any help would be great

Can i use a class for this or do i need to use a type def
what i am trying to do is have a parent cluster witch has a file name and some free space to put is children's data in with decorations at the bottom.
i then need to have a child with a graph in the middle blank space of the parent.
i also need to have another child with a table in the middle blank space.
can i do this with classes or do i need to use typdefs.
tks in advanceHello vivi,
I'm not entirely sure what you mean. The classes that you create in LabVIEW 8.2 are meant to be containers for data and methods, not displayable items. Even though a class's private data members are defined in a cluster, you can't think of a class and a cluster as the same thing. A cluster is an object that you can use to bundle different kinds of information together. You can also design a cluster to be displayed on a front panel.
If you want to use LabVIEW's object oriented features, I would suggest creating a class which stores your objects data (non displayable). You could then create a method on your class to convert some of its internal data into a cluster which can be displayed to the user.

Can I use Partial class to enhance a typed dataset without losing the custom code?
Hi All,
I wanted to see if I could use a Partial class for one of the datatable classes to add custom code so that when the dataset is regenerated I don't lose my code.
Partial public
Class
WA_MMTP_TrackerDataSet1
'Code for dataset
Partial Public Class PATIENTSTableAdapter
<Global.System.Diagnostics.DebuggerNonUserCodeAttribute(), _
Global.System.ComponentModel.Design.HelpKeywordAttribute("vs.data.TableAdapter"), _
Global.System.ComponentModel.DataObjectMethodAttribute(Global.System.ComponentModel.DataObjectMethodType.Fill, true)> _
Public Overloads Overridable Function FillbyClinicianId(ByVal dataTable As WA_MMTP_TrackerDataSet1.PATIENTSDataTable, ClinicianId As Integer, sql As string) As Integer
Dim dd As System.Data.SqlClient.SqlCommand
dd = new System.Data.SqlClient.SqlCommand
dd.CommandText = Sql
dd.Connection = OpenConnection() ' UsersTableAdapter1.Connection
Me.Adapter.SelectCommand = dd 'Me.CommandCollection(0)
If (Me.ClearBeforeFill = true) Then
dataTable.Clear
End If
Dim returnValue As Integer = Me.Adapter.Fill(dataTable)
Return returnValue
End Function
'Other code for datatable
end class
end class
I'd like to take the function FillbyClinicianId and put it in a separate partial class like so and remove the function by the same name from the original file (dataset file):
Partial Public Class PATIENTSTableAdapter
<Global.System.Diagnostics.DebuggerNonUserCodeAttribute(), _
Global.System.ComponentModel.Design.HelpKeywordAttribute("vs.data.TableAdapter"), _
Global.System.ComponentModel.DataObjectMethodAttribute(Global.System.ComponentModel.DataObjectMethodType.Fill, true)> _
Public Overloads Overridable Function FillbyClinicianId(ByVal dataTable As WA_MMTP_TrackerDataSet1.PATIENTSDataTable, ClinicianId As Integer, sql As string) As Integer
Dim dd As System.Data.SqlClient.SqlCommand
dd = new System.Data.SqlClient.SqlCommand
dd.CommandText = Sql
dd.Connection = OpenConnection() ' UsersTableAdapter1.Connection
Me.Adapter.SelectCommand = dd 'Me.CommandCollection(0)
If (Me.ClearBeforeFill = true) Then
dataTable.Clear
End If
Dim returnValue As Integer = Me.Adapter.Fill(dataTable)
Return returnValue
End Function
end class
But when I try this, the compiler gives the following errors:
Error 91 'Adapter' is not a member of 'AttendTrackerFull.WA_MMTP_TrackerDataSet1.PATIENTSTableAdapter'.
Error 92 'ClearBeforeFill' is not a member of 'AttendTrackerFull.WA_MMTP_TrackerDataSet1.PATIENTSTableAdapter'.
I guess I'm a little confused. once code is moved into the custom partial class it seems to lose any knowledge of the main class file and any references in the class. Am I doing it wrong? or is it a restriction of the .Net since it is in another
file. If its because its in another file, my next question would it be better to take the partial class I created to contain my custom code, should I just move my partial class to the bottom of the dataset.designer.vb file? But if I do this, wont it still
erase my custom code. Any suggestions?
Thanks
MichaelThanks for the reply.
They are compile time errors, but the error shows up even before compiling, so I guess it would be designer time exception also.
What I did the other day was to create a new class file (didn't add a namespace statement to class) then added the code in prev message. This morning I added a new module and added the prev code in it incased in the namespace
namespace ADO.NET.DataSet1TableAdapters statement. But I still have the same errors messages. I tried
to set the Custom tool.namespace property of the dataset to WA_MMTPDataset and then did the following in a module:
namespace WA_MMTPDataset
Module Module4

dd.CommandText = Sql

dataTable.Clear

dd3.CommandText = Sql
dd3.Connection = OpenConnection()

Can I use math functions in a PDF?
I've got a document where scores are entered (1 - 5) in numeric fields. Is there a way to add these and average them, and output that value into another field on the fly, or by pressing a button on the form?
you can also do it in formcalc.
For adding use the sum() function.
For averages use the Avg() function.
You could put the formula in the calculate event of the field you want the results to show in and it would appear as soon as the initial numers are entered, or if you want to use a button you could put the formula in the click event of the button. -

1.) Look at the stack trace and find the position highest on the stack trace that is your code (i.e. not a class that you didn't write) and look into that line and try to find out what you might be doing wrong there (or just before that)
2.) Look at the API documentation of the Exception class and find out when it's thrown (in this case: look at http://java.sun.com/javase/6/docs/api/java/util/UnknownFormatConversionException.html )
If you still can't figure out the problem post the line where the problem occured. -

PoonamHi Faisal,
Just to correct you it's "Methods of Global Persistent Classes".
Not to hide my ignorance in OOPs, but i don't think persistent classes should be used for mundane selects. It's much easier to write, maintain & troubleshoot a select construct than a persistent class
