Get popupscreen user input and store it in the variable
Hello world. I have a screen that is pushed to start the application
pushScreen (new SPScreen());
In the constructor of the form, I push an extension of popupscreen in the stack to get an int from the user through TextField amount.
UiApplication.getUiApplication () .pushGlobalScreen (new SplashScreen(), 1, UiEngine.GLOBAL_SHOW_LOWER);
In the popuupscreen, I store the entry under int amount;
public void fieldChanged (field field, int context) {}
name = nameTxt.getText ();
quantity = Integer.parseInt (amountTxt.getText ());
Close();
}
};
Now I want int amount; in my screen to shoot the user supplied value and whenever you click on a button Add the amount in total, each time increasing the total amount.
public static int amount;
total int = 0;
...
amount
= OptionScreen.amount;
Total = total + amount;
No matter how many times you press the Add button it only changes the total amount. For example, if I enter 6 as the quantity and press the button 3 times I want the total 18 years, but the total is still only 6.
I'm sure there's probably a way to pass a reference to the variable, but I have a similar situation where I have a variable which is accessible by a certain screens and can be changed in multiple screens as well. I delcare a class called globalVars and put the variable.
public class globalVars { public static int total; }
Do only access you anywhere with globalVars.total.
Kind regards
Scott

Collection of user input and store it
Could someone help me with detailed instructions on how to do it. I have internet search and my huge Director books for hours for a kind of pre-packaged instructions on obtaining the user text entry, but no luck. I have my set interface in place and these are the pieces of info I want:
Username (limited to 30 characters)
Connection (between 6 and 15 characters)
Password (between 6 and 15 characters)
Password2 (must match the password)
Correo electronico (must contain a sign @)
I don't know if I'm supposed to use text field, or component of flashTextInput. And how can I make the character limiting and looking for a character? I know it must be editable. How can I then collect this information with a "submit" button and save it in a file encrypted with the buddyAPI? And then how to get some of these data items and use them in this film or another in the program?
Thanks in advance.There are many ways to go about this, but I would like this:

How to capture user input and display it in another text field
Hey there,
I create a simple screen that allows a user to enter text and I want to take what they get and appear in other fields of text on the same screen, so they do not have to retype. I'm using AS3. I read an article that gave me a few tips, but the code I use is not doing the job. I'm pretty new to Flash, so any help would be appreciated.
Here is what I use:
var Description: String;
myText_txt.addEventListener (Event.ENTER_FRAME, assignText);
function assignText(myevent:Event):void {}
Description = myText_txt.text;
}textResults_txt.text = Description;
My thoughts after reading the article (I think it's from Ned) should follow the first text field, myText_txt and assign this text to the variable Description. Then I tried to assign the variable Description to another field of text called textResults_txt. However, when I type in the first text field, nothing appears in the second.
Any ideas? Am I using the wrong method to monitor the text box?
Thank you for your time.
Stephen
You don't want to lose an ENTER_FRAME for this. You must assign an event listener for the input textfield that listens to a CHANGE event. The event handler for this listener function will simply match the textfield in the first second.
myText_txt.addEventListener (Event.CHANGE, assignText);
function assignText(evt:Event):void {}
textResults_txt.text = myText_txt.text;

Precise triggering voltage input and output generation in the DAQ Assistant
Hello
I wonder if anyone has come across a simular problem with the synchronization of input and output voltage. I use a box 11 LabView and NI USB-6259. I have been using the DAQ Assistant to configure the input and output channel. In particular, my task is to generate a single rectangular "pulse" as the output voltage to drive a coil and once the pulse went to get a signal from a sensor of magnetic field and get a power spectrum. This means that the order and the time during which the DAQ Assistant is used is extremely important. For example, the output voltage channel must be opened first for 2 seconds. Subsequently, the channel of input voltage must be open for 1 second, in which the sensor signal is obtained and post-processed. Only after these tasks are performed in this order he can can be repeated in a loop until the experiment is over. I don't know how to trigger data acquisition assistants (one for entry) and the other for the voltage output correctly. Y at - it a trick?
See you soon
Michael
Hi Dave,.
Thank you that I wired the error strings but the timing issue was unrelated to it. In the DAQ assistant, I simply had to choose the continuous aquistion of the 'samples' methods 'N-switch' for input and output voltage and all works fine now.
Thanks again

XDB user name and password to access the page configuration EPG on a pluggable database APEX
Hello
I have a base shared of the Oracle (12.1.0.2) 12.
I have an APEX PDB 5.0 file. There is no APEX installed on the CDB (root).
Connected to the PDB, the registry says:
Name of the ID Version State
------------ ----------------------------------- ------------ ----------
APEX Oracle Application Express 5.0.0.00.31 VALID
I want to configure the EPG for this PDB.
I did the following (in this order):
(1) race: apex_epg_config.sql
(2) race: exec dbms_xdb.sethttpport (8080) - the firewall is open for this port
(3) race: change the anonymous user account unlock;
(4) run:
Start
() DBMS_NETWORK_ACL_ADMIN.append_host_ace
Home = > ' *',
As = > xs$ ace_type (privilege_list = > xs$ name_list ('connect'),)
principal_name = > "APEX_050000"
principal_type = > xs_acl.ptype_db));
end;
/
I find myself with the APEX-based users:

When I run from the browser:

I get the messge:
"APEX request a user name and password XDB"
Does someone has encountered this situation in a PDB file?
Thanks in advance for any information.
Thanks and greetings

Hello
Manufacturers recovery disks normally do not have Service Options; they are normally a relocation to the factory only settings option.
Acer definiterly only reinstall to factory settings, new condition.
Here is the guide to repair Options using a Vista DVD from Microsoft.
If a friend or a work acquantance of yours has one, you can borrow and use it for repairs.

If you do not or can not borrow a Microsoft DVD there is a download of a file ISO of Vista Startup Repair available that you can put on a Bootable floppy to make the above startup repair and that the method is recommended by a large number of posters in these Forums.

4 x Vista computers
1 x XP computer acting as a server file, all the data in the "shared folders".All 4 Vista computers were to access shared data on the XP machine for two years without problem. All of a sudden this week one of the Vista computers "Frequently" but not always ask for a username and password to access the machine XP - not only shared folders, but still a list of shared resources on the machine XP via my network places is the result in the box of "connect to" request credentials to appear. All 3 other Vista machines have no problem to access the XP machine, so the problem must be with the a Vista machine.
To put a spanner in the works as I have said in this case "Frequently" and by that I mean probably 9 of the 10 connection attempts. Let's say, you can see the name of the computer in my network places, you double click it and have asked for credentials, cancel the attempt and to repeat 4 or 5 times and then you could get display shared resources without going into the details of connection. For a few minutes, you might be able to access all the shared data and to navigate through the folders, but then all of a sudden have asked you credentials and can not access to anything, even the files accessed you seconds before.
Lets say you are able to access the shared folders, you navigate to the Parent folder, then under A folder, then a subfolder B, go back to A notebook, then try to access folder B even once and you get guest credentials, quit out of the network completely locations, navigate back to the XP via Network Places and this machine you not even be able to display all the shared resources on the XP machine.
I've also set up a shared folder on a Vista machine with matching username and password on the machines and the Vista machine with the get the problem exactly the same problem so this definatley Vista machine with the question and not sharing files on the XP machine.
Someone at - he met before or have any suggestions?
Hi MikeBarnes,
You can check in the Analyzer for performance and reliability.
Step 1:
To start reliability monitor and performance monitor
a. Click Start, right-click computer and click on manage.
b. in the Microsoft Management Console navigation tree, click on performance and reliability.
Step 2:
You can also try a system restore to a point before the problem started.

Then click the icon for web services enabled that it says it needs an update, I try this and it never ends. Goes back to the home screen and I can't access it from any computer on the network that I have the software installed on.
Windows 7 64 bit on a computer and windows vista home basic svc pak 2 other.
I just tried again, reset the values by default, restored the wireless connection to the router Linksys, click on icon for web services, put on day of technology required, clicked on OK, started download again, got 57% and are returned to the home screen!
When I tried again... he hung up on the screen asking me if I want to activate the automatic update. Had to turn on the printer works to clear the screen. I think I got a LEMON! If I don't get any help or solution to that soon he'll be back!
Hi Jasonlq,
This error sometimes occurs when the network connection is slow. The upgrade file can not be downloaded correctly and it times out.
Recommend that you restart the printer, and then try again. Also try and see if other devices in the same network are hogging the bandwidth of the internet connection to the downturn.
Let me know how it goes.
