Asking user for value to resize?
Hello guys. I want to make a quick script that will take the selected finder item, ask the user for a value to resize (In the form of a dialog box) and then using that percentage, execute the scale image function under preview. Does anyone know how I could do this? Thanks!
Get Selected Finder Items
Scale Image (Preview Library, check the "show when run" option)
As written here, this works on the original. Put a Copy Finder items in Place of Get Selected Finder items if you want to work on a copy.

Upload file without asking user for the file
Hi,
I need to upload a file to server, but from my code, not using the file upload from page.
I have created a xml file and I need to upload to server when user open a web browser (without asking user to select a file).
How do I proceed??, or what kind of libraries do I must use?

Hi,
thanks for answer.
Let me try to explain again (I think its very simple).Simple, yes. But not very thorough.
I have developed a web application using JSF.So all the code is running on the server, right? There are no Applets, Applications or WebStart applications involved. Right?
My application has a splash screen where I show data. I have developed a bean to connect to my database (sql server), extract this data and create an xml (using DOM) file like:
<news>
<simplenews id="1"> Value </simplenews>
</news>And that bean runs ... where? Server again?
(important step) Once I have created the xml file in my bean I want to upload to the server to a place like /WEB-INF/news.
If the code is running on the server, then "uploading" is the wrong term, as there's nowhere to upload to, since you're already on the server.
This may sound like nit-picking, but you're sending us on a wrong trail with this phrase.
Once the file is on the server with another bean I read the xml fileWhy don't you simply store it in the application scope and let everyone access it from there? It doesn't sound as if the XML is huge.
As you can see I haven't a web page where to show an upload file componetYou also don't want to "upload" anything from the client, from the sound of it.
You simply want to transfer data between to server-side components, if I understood you correctly. -
Best way to ask user for duration ??
I am wondering what the best way to set up a dialog to ask the user for a duration is ?
I need to query the user for the following duration example 1 month 3 days 5 hours 15 mins
I have tried messing around with JSpinners with date formats but they really only work with fixed calendar dates not calendar durations...
Any ideas on a neat approach..
Currently i have an individual number spinner for each of the items which looks ugly and is hard to manage as you have to take care of up to 23 hours but 24 is one day so one day etc etc..
Thanks in advance
-AlanYou continue along the same lines; keep the DTO in the session as an attribute. When you display your JSP, read the appropriate values for choices from the DTO and set your checkboxes/ radio buttons to 'selected' if they should be.
When the page is submitted, read the parameters from the form submit and update your session attribute ( DTO ) to reflect any changes the user might have made like selecting a new option or deselecting a previously selected one.

Custom TrustManager example which asks user for trustability
Hi!
For I needed a trustmanager which shows an untrusted server certificate to the user and asks him if the certificate can be considered trustable I wrote an own trustmanager. As it took much time to find out how to do this here is my code to shorten your time if you need a similar functionality:
NOTE:
If a certificate is declared trustable by the user it is stored in a local keystore file. So if you use the code in an applet you need to sign it to get the appropriate permissions.
To use it you have to put the following code where you get your SSLSocketFactory:
try{
SSLContext sslContext=SSLContext.getInstance("SSL","SunJSSE");
TrustManager[] tm={new StoreCertTrustManager()};
sslContext.init(null,tm,null);
factory = ( SSLSocketFactory) sslContext.getSocketFactory();
}catch(Exception e) { ... }
Here is the implementation of the StoreCertTrustManager:
* This class implements a TrustManager for authenticating the servers certificate.
* It enhances the default behaviour.
class StoreCertTrustManager implements X509TrustManager {
/** The trustmanager instance used to delegate to default behaviour.*/
private TrustManager tm=null;
/** Password for own keystore */
private final char[] keyStorePassword=new String("changeit").toCharArray();
/** Path to own keystore. Store it into the home directory to avoid permission problems.*/
private final String keyStorePath=System.getProperty("user.home")+"/https-keystore";
/** The stream for reading from the keystore. */

/** The instance of the keystore */
private KeyStore keyStore=null;
* Creates a TrustManager which first checks the default behaviour of the X509TrustManager.
* If the default behaviour throws a CertificateException ask the user if the certificate
* should be declared trustable.

Cant get IMAQ write file 2 to ask user for the path.
I am currently using an IMAQ write file 2 to create a .bmp image. I have the VI attached to a control path that allows the user to enter the path where they want to save the file. However I dont want the user to have to make sure they typed the path in before the IMAQ write file executes. I want the program to work so that when the IMAQ write file executes a window appears asking the user where they would like to save the file. If someone could help me out I would appreciate it thanks.
Solved!
Go to Solution.Use the File dialog VI under File I/O >> Advanced File Functions palette

Is there a standard dialog for this?
I googled but the things I found was
* JDatePicker (some sort of commercial product - ?)
* JXDatePicker (belongs to org.jdesktop.swingx, a packet I cannot import)
sure there must be a simpler way?of you can try to find out plenty od JDatePicker, JDate or JCalendar
then google returns ...., check and compare its funcionalities with calendar by "toedter"
on check posts on some forums (inc. this one), its can get you answer -
Ask user for input after Workflow has already started?
I am in the process of creating an "expense report" declarative workflow in Designer. I want to have it start automatically when a new document (here, an Excel file) is uploaded to the Library. I also want some user input (e.g. "Is this
ER urgent?"). Is there a way to this without requiring the workflow to start manually?You can have required information as metadata on your library and user needs to fill those information. You read that information in your workflow.

How can I keep the name of the user around for each JSP without asking user
I have a number of JSP pages that I give the user access to once they login successfully. I want to be able to keep the name of the user present on every page without having to ask them for it each time.
How can I do this? Currently I have a user object that is access through use of a request bean in my JSP's.
Any suggestions???Thanks for the help. A few questions though...
Can you just clarify how the 2 different SessionTest2.jsp's differ. I am right in thinking that the second one will instantiate a new bean object which if I do every time I go to the page, I will be getting the same name but in a different session each time. In the first SessionTest.jsp, I get the same name but from the same session object each time??
Please clarify???
SessionTest1.jsp
<%@ page language="java" import="test.*" %>
<jsp:useBean id="testBean" scope="session"
class="test.TestBean" />
<jsp:setProperty name="testBean" property="name"
value="ZZZZZ" />
<jsp:setProperty name="testBean" property="status"
value="Married" />
<%
response.sendRedirect("SessionTest2.jsp");
return;
%>
SessionTest2.jsp
<%@ page import="test.*" %>
<jsp:useBean id="testBean" scope="session"
class="test.TestBean" />
<%
out.println("User Name is : "+testBean.getName());
%>or SessionTest2.jsp
<%@ page import="test.*" %>
<jsp:useBean id="testBean" scope="session"
class="test.TestBean" />
<%
TestBean testBean =
(TestBean)session.getAttribute("testBean");
out.println("Name is : "+testBean.getName());
%>Hope this helps.

Can anyone tell me syntax of select statement where i can ask user to enter value .None. The SQL engine resides on the server. It is incapable of prompting for data entry on the client.
The client interacts with the user. The client is suppose to:
a) prompt for variable values
b) send a SQL statement to Oracle
c) bind values to bind variables in the SQL statement
for example i am trying to use belowthing but it displaying error
select * from emp where empname=:empnameIn SQL*Plus, you need to create a bind variable:
SQL> var empname varchar2(200)
And then assign a value to it:
SQL> exec :empname := 'John Doe';
Note that this is still not ideal - as the assignment is also done via the server and sends a PL block to the server. This block contains non-sharable code and this can lead to fragmentation of the server's Shared Pool.
But it does illustrate the basic principle. -
I bought a iPhone and I was able to log into my iCloud with no problem and when I tried to update it it kicked me out and now it's asking me for the old apple user please help what can I do...?
Contact the original owner, and ask them to remove the device from their icloud.

Hi All,
I have a requirement where i need to get the user entered value in the Parameter of a concurrent program while submitting it. i tried to query the FND_CONCURRENT_REQUESTS table but in that it stores the ID values from the value set of the Parameter.
After submitting the Concurrent request when we click on the view Details button it opens a form where it displays the arguments in the parameter field . i want to get that string.
Thanks a lot in advance for your time and help.

Trying to run it as the current user, or as one from a different account(administrator in this case) also doesn't work.
I think the client is not able to do a HTTP POST
to the WLS server but it can do a HTTP GET.
I dont know why.

Hi,
I deployed a rpc web service using WLS 7.0 SP2 in HP-UX 11 environment.When I
invoke the web service through my browser (IE 6.0) using the web servicesurl,
it brings my service method correctly. From there, if I click the invokebutton
it asks me for a network user name and password under "weblogic" realm???If I
provide the admin user credentials (which I supplied while creating mydomain)
it is not accepting that it keeps popping up this network user passwordwindow
over and over. Not sure which username/password I have to provide here tosee
the result of my service.
If I try to invoke the web service through my client (static) I am gettinga connection
refused exception. I guess either way, I am not able to access my webservice.
In the attached file, I have cut and pasted the client stack trace as wellas
the server log trace from weblogic.
Any ideas would be highly appreciated.
Thanks,

Itunes keeps asking me for a user name and password when I first open it.
I do not allow apple to access my library or my hard drive because you guys are predators, and I have NO interest in using the app store. I have disabled access to the store, so i do not know why it keeps asking me for a user name and password. You have NO right to see the music THAT I PURCHASED a loooooooooong time ago. It is my license. I should be able to play it whenever and wherever I like...and NO, I do not burn and copy my music. I just want to play it on MY MACHINES. So, I do not need your useless snooping, which is probably the reason you want me to log in. Who do you think you are? You didn't write the songs. You just sell licenses. Period. And I purchased mine, thank you. I no longer use your store for these reasons. I use Amazon.
Not control-R. Command-R. Shut the computer down. Reboot it. Hold down cmd-R when you hear the chime. Keep it held down and you should see the Lion recovery partition.

<Email Edited by Host>Welcome to the Apple Community.
I have asked for your email address to be edited out. Posting your address in an open thread is a sure way to be bombarded by unwanted email, remember it will be here long after you have resolved your problem, for automated detection software to find.
If you want people to contact you, enable others to see your email address in your profile.
This feature has been introduced to make stolen phones useless to those that have stolen them.
However it can also arise when the user has changed their Apple ID details with Apple and not made the same changes to their iCloud account/Find My Phone on their device before upgrading to iOS 7.
The only solution is to change your Apple ID back to its previous state with Apple at My Apple ID, verify the changes, enter the password as requested on your device and then turn off "find my phone".
You should then change your Apple ID back to its current state, verify it once again, delete the iCloud account from your device and then log back in using your current Apple ID. Finally, turn "find my phone" back on once again.
Apple Topluluk hoş geldiniz.

FROM ((employeeuddslink INNER JOIN employee ON employeeuddslink.[employee_ID] = employee.[ID]) INNER JOIN payudds ON employeeuddslink.[payudds_ID] = payudds.[ID]) INNER JOIN data ON employee.[Emplid] = data.[Emplid]
GROUP BY employee.Name, employee.Emplid, payudds.Udds, data.Budget, data.Fund, data.FTE, data.[Annualized Rate], data.[FN Dist Pct], data.Udds, data.Project, data.[Empl Class], employeeuddslink.employee_ID, employeeuddslink.payudds_ID;
When I run this it ask for value for employee.Emplid.
I just want my query to run. How do I resolve this.
Regards, HiteshFROM ((employeeuddslink INNER JOIN employee ON employeeuddslink.[employee_ID] =
employee.[ID]) INNER JOIN payudds ON employeeuddslink.[payudds_ID] = payudds.[ID]) INNER JOIN data ON
employee.[Emplid]
In the FROM you have employee.[ID] and employee.[Emplid] as both being in table [employee].
