You need to point it at

newFile is fine, but newFile isn't called beforethe
doc= line.actually i have this a bigger program what i have
send before. i m getting a object of JEditorPane in
newFile() and asssigning it to epMain.
Thats why i want to access epMain's that value what i
have setted in newFile so i dont created a new object
and assigned in epMain as like
this.epMain= new JEditorPane();so how I can access epMain's that value what i have
setted in newFile()
here is actual newFile method
public void newFile()
Component comp=newEditPane();
JInternalFrame iFrame=makeIF(comp,"Untitled");
iFrame.setVisible(true);
if(iFrame.getDesktopPane().getSelectedFrame()!=null)
selectedFr=iFrame.getDesktopPane().getSelectedFrame();
Container iContent = selectedFr.getContentPane();
JScrollPane
jsp=(JScrollPane)iContent.getComponent(0);
JEditorPane
e=(JEditorPane)jsp.getViewport().getView();
this.epMain=e;
Hmmn... Rakesh you're so makulit. Do you know what null pointer means? Here read the docs API,
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/NullPointerException.html
You're displaying html using JEditorPane, why dont you try org.jdesktop.jdic.browser.WebBrowser?

How can I import data using .dmp into the table which has more columns then in import

I am building the history for warehouse purpose on Oracle 8i database and want to use the old import (.dmp) files (from oracle 7.3.4) to import data but the underlying table is having few more columns which are not in my old DMP file .. how can I import the data into these altered tables while using the same *.imp files .
Any solutions ?

That is the most obvious solution .. but think of the case when my operational database which is the source of my data is undergoing changes every quarter i.e after every 3 months there are some changes on underlying table structures which means structures of my import files will always be different after evry quarter .. you can imagine the number of temporary import structures I need to create .. can't there be a solution wherein I can write an SQL over the import file to read the data in required format ..

How can I call actionListener using JavaScript

Dear Programmers
I have to use javascript in order to call a specific actionListener when a window is close. Therefor I inserted the following code to the jsp:
<script type="text/javascript">
window.onunload = function(){......};
</script>
But how can call a specific actionListener? I saw that I can use submit(), but this method doesn't perform any actionListener. I didn't find where the actionListener is specified after doing "view source" on the browser.
Please help me

Hello,
I think you can do this:
<h:form id="formId">
<h:commandButton id="buttonId" actionListener="..." />
Then you can call:
document.forms.formId['formId:buttonId'].click();
to invoke the action listener. If you don't want to display the commandButton on screen, you may apply a css style to hide it.

How can I set CameraRAWOpenOptions using Javascripts in Photoshop CS6?

I have been unable to set CameraRAWOpenOptions in scripts that worked fine for me in Photoshop CS5 but now do not work in Photoshop CS6. There are no error messages when I run the scripts, and they appear to finish okay, but the images come out unadjusted. Below is the essence of how I'm trying to do it. When I run these scripts in Extendscript (CS5 or CS6 does not make a difference), Photoshop CS6 simply uses its own default (saved) settings, but CS5 would allow the overrides. I did change the default settings in CameraRAW in CS6 to use the default lens correction profiles available from the EXIF data, and I'm wondering if that rendered the script unable to change any of the rest of the settings.
Here's how I have the code:
var RawOptions = new CameraRAWOpenOptions;
RawOptions.settings=CameraRAWSettingsType.CUSTOM;
RawOptions.exposure=+2.00;
RawOptions.vignettingAmount = 0;
RawOptions.vignettingMidpoint = 0;
RawOptions.contrast = 50;
RawOptions.saturation = 0;
RawOptions.shadows = 0;
RawOptions.luminanceSmoothing = 0;
var JPGopts = new JPEGSaveOptions;
JPGopts.quality = JPEGquality;
//Perform the loop through the files
app.open(testListing[0], RawOptions, false);
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
for (var nfile = nstart; nfile < nstop; nfile++)
    app.open(testListing[nfile], RawOptions, false);
    FnameSave = new File(SavePath+"/"+testListing[nfile].name);
    app.activeDocument.saveAs(FnameSave, JPGopts, false, Extension.UPPERCASE);
    app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);

I would collapse and expand the toolbar windows by using the double arrow icon?
Doing this will almost give you your full screen?
Or you can hit 'Tab' and it hides your tools when you don't need them?

How can I migrate data from an old MBA to a new one without having access to the screen of the old one? The screen of the old MBA is damaged !

How can I migrate data from an old MBA to a new one without having access to the screen of the old one? The screen of the old MBA is damaged !

If your "older" MBA has a Thunderbolt port then it isn't that old. See Target Disk Mode about how it's used. Note that without a monitor you won't be able to tell from the screen when it has fully started, and if it succeeded in starting in TDM. If it did, then the hard drive should appear on the Desktop of your new computer. You can then access it to transfer your files. You can even use Migration Assistant or any backup utility to transfer data. Just don't try to transfer system files.

Is there a way that you can have two different text fields (email, phone) that one at least one of them must be completed before submitting the form? Can it be done using javascript in the validation tab? if so, how?

Is there a way that you can have two different text fields (email, phone) that one at least one of them must be completed before submitting the form? Can it be done using javascript in the validation tab? if so, how?

Here is one solution:
// mouse up action for submit button;
function GetField(cName) {
// get field object for cName field with error checking;
var oField = this.getField(cName);
if(oField == null) app.alert("Error accessing field named " + cName + "\nPleae verigy field name, spelling and capitalizeation.", 1, 0);
return oField;
} // end GetField function;
var oPhone = GetField("phone");
oPhone.required = oPhone.value == oPhone.defaultValue;
var oEmail = GetField("email");
oEmail.required = oEmail.value == oEmail.defaultValue;
if(oPhone.required && oEmail.required) {
app.alert("Missing required fields.", 1, 0);
} else {
app.alert("Submitting form", 3, 0);
// additional code for submission;

How can I import data from a csv file into databse using utl_file?

Hi,
I have two machines (os is windows and database is oracle 10g) that are not connected to each other and both are having the same database schema but data is all different.
Now on one machine, I want to take dump of all the tables into csv files. e.g. if my table name is test then the exported file is test.csv and if the table name is sample then csv file name is sample.csv and so on.
Now I want to import the data from these csv files into the tables on second machine. if I've 50 such csv files, then data should be written to 50 tables.
I am new to this. Could anyone please let me know how can I import data back into tables. i can't use sqlloader as I've to satisfy a few conditions while loading the data into tables. I am stuck and not able to proceed.
Please let me know how can I do this.
Thanks,
Shilpi

G'day. I am using iMovie 11 and need to clear disk space. How can I do that using an external drive, leaving me the option to go back and make changes or access old events or projects from that external drive?

G'day. I am using iMovie 11 and need to clear disk space. How can I do that using an external drive, leaving me the option to go back and make changes or access old events or projects from that external drive?

The slightly bigger question is whether you want to move all movie content to the external drive (essentially meaning that drive will always need to be attached when you're working with your videos), or whether you just want to archive older videos off to the external drive.
If you want to move all videos, then just move the 'Movies' folder in your home directory to the external drive, then create an alias of the external 'Movies' back in to your home directory. Now the 'Movies' icon in your home directory will point to the external drive and everything will just work (as long as the external drive is attached when you launch iMovie)
If you want to archive older movies then each Movie should have its own subdirectory within your Movies folder. These can easily be moved off to the external drive, and moved back should you ever need to work on those movies again.

How can you change data on a SQL 2012 application database that uses availability groups from BizTalk server?

If you use the WCF-SQL adapter it is recommend that you set UseAmbientTransaction to true if you are changing data. I think this requires MSDTC to be enabled on the SQL server that you are changing the data on. (http://msdn.microsoft.com/en-us/library/dd787981.aspx)
I think that Availability groups does not support MSDTC. (http://msdn.microsoft.com/en-us/library/ms366279.aspx).
