How to close an error dialog using software control without user's response

Hi all,
I was wondering if there is a way to press "continue" button programmatically when an error massage pops up. In USB communication application, if an error occures because of disconnection of USB cable, in this case VISA would generate an error windows, I am working on an effect that when the user reconnect the USB cable to the system, the error massage would disappear automatically. Your ideas would be appreciated.
Thanks & Regards
Peter Huang

Thanks for your reply, I think I didn't make myself clear enough. I mean in my application, We hope user to see a popo up warning if USB cable somehow accidently disconnected. But we hope it would automatically close by software condition say detecting the reconnection of USB. I am thinking a way to avoid the susppession of code execution when error dialog box comes up, so that my programme would wait and hold an error window until certain boolean condition is met, then finally close itself. So far, the information I found is simulating key stroke, another possible option is using invoke node with OK button as a control. Any other ideas?

when i click the buttonlink the dialog box is not in a stable state that is its will appear and within a second it will disappear .. can any one of them can suggest me how to create a modeless dialoge using commandlink or by jsf option button
regards
subramanian

If I had to guess (and I do :), the onclick is firing, bring up the dialog, but the commandLink causes a form submit, so the page is submitted. There is no action on the commandLink, so it's navigating back to the same page, causing it to refresh and your dialog to disappear. It would appear to me that you need a h:outputLink or simply <a href="# onclick="..." /"></a>

How to select "ISO A" (auto) using Custom Controls with lever assigned to ISO change?

On 7D Mark II with firmware 1.0.4, I have used Custom Controls to assign ISO change to the lever. However, it is not possible to change ISO to "ISO A" (auto).  How to select "ISO A" (auto) using Custom Controls with lever assigned to ISO change?

Follow Up:
Ok so ive changed things up a bit and have had some more success.
I have used a Switch statement in my For loop to perform different actions based on the item selected.
The code looks like this:
Workbook.Content.Table1.Row3.AppropriationDetails.Row4.Cell1::change - (JavaScript, client)
var fFrom = xfa.resolveNodes("Workbook.Content.Table1.Row3.AppropriationDetails[*] .Row4.Cell1");
var fTo = xfa.resolveNodes("Workbook.Content.Table2.Row3.AppropriationDetails[* ].Row4.Cell1");
for (var i=0; i <= fFrom.length-1; i++) {
     switch (fFrom.item(i).rawValue)
     case "Option 3":
     fTo.item(i).rawValue = "Enter the details in the field below";
     break;
     default:
     fTo.item(i).rawValue = fFrom.item(i).boundItem(xfa.event.newText);
     break;
This code solves my problem but has thrown up a new issue:
When i select Option 1 or 2 from the dropdown list the change in the text field is instantaneous, however if I select Option 3 it wont appear in the text field until I either select Option 3 a second time or select another item. Its as if the text field is a selction behind what I have enterd in the dropdown list.
Any thoughts?

How to solve power error when using USB camera adapter in your camera

Hello Everyone,
First of all I wanna say reducing the output of the USB camera adapter from 100mA to 20mA just to save battery life is by far the most incredible adjustment in the history of @)#*$#%*($#!
I know most of us bought the USB Camera adapter so we can use it as a USB adapter for the Camera (saves us from taking the memory card on and off the camera) but sadly the "Ginues Apple" reduced it to 20mA which decreases the range of cameras and flash drives that will work with it. I use Gopro Hero 3+ black and everytime I plug it with the adapter to my ipad I keep on seeing this @#@$#@ power error. I didn't want to waste the expensive adapter so I tried to look for a micro sd card reader but I don't think 20mA readers still exist.
Now to solve this problem is very simple add a power source to help that 20mA up, most of the my friends bought a powered port hub but it's not my type because it's bulky, needs an outlet and not portable.
So I found a better solution on how you can add a power source and still be portable, the answer is power bank or portable charger.
Things you need:
Camera
USB camera adapter (Ginues Apple product)
Power bank (I'm using 8,400 mAh)
Dual USB Male to 5 Pin Mini USB Y Cable
Ipad
Procedure:
Camera --- 5 Pin Mini USB ------------------ USB camera adapter ---------- Ipad
'---------- Power Bank
Attach you camera to the 5 pin mini usb then the USB1 male to the female apple's USB camera adapter then to the Ipad. = this will show the power error.
Then attach the USB2 to the power bank/portable charger to power it up.
your welcome

How to close a popup dialog?

Looking at the Scenebuilder1.1 Login sample, a new scene is created which is placed on stage.
How would such a popup get closed and get back the original main screen?
    private Initializable replaceSceneContent(String fxml) throws Exception {
        FXMLLoader loader = new FXMLLoader();
        InputStream in = Main.class.getResourceAsStream(fxml);
        loader.setBuilderFactory(new JavaFXBuilderFactory());
        loader.setLocation(Main.class.getResource(fxml));
        AnchorPane page;
        try {
            page = (AnchorPane) loader.load(in);
        } finally {
            in.close();
        // store the stage height in case the user has resized the window
        double stageWidth = stage.getWidth();
        if (!Double.isNaN(stageWidth)) {
            stageWidth -= (stage.getWidth() - stage.getScene().getWidth());
        double stageHeight = stage.getHeight();
        if (!Double.isNaN(stageHeight)) {
            stageHeight -= (stage.getHeight() - stage.getScene().getHeight());
        Scene scene = new Scene(page);
        if (!Double.isNaN(stageWidth)) {
            page.setPrefWidth(stageWidth);
        if (!Double.isNaN(stageHeight)) {
            page.setPrefHeight(stageHeight);
        stage.setScene(scene);
        stage.sizeToScene();
        return (Initializable) loader.getController();
    }

Thanks for your reply. I rewrote the sample to do this - created a new Stage, and it worked. :)
    <T extends ControllerBase> T replaceSceneContent(T controller, String fxml, String message) {
        try {
            AnchorPane page;
            FXMLLoader loader = new FXMLLoader(getClass().getResource(fxml));
            page = (AnchorPane) loader.load();
            Stage dialog = new Stage(StageStyle.UTILITY);
            dialog.initOwner(MainPane.primaryStage);
            dialog.getIcons().add(new Image("/resources/my-icon.gif"));
            dialog.initModality(Modality.WINDOW_MODAL);
            Scene scene = new Scene(page);
            dialog.setScene(scene);
            T c = loader.getController();
            c.stage = dialog;
            c.setMessage(message);
            dialog.showAndWait();
            return c;
        } catch (IOException ex) {
            Logger.getLogger(main_screenController.class.getName()).log(Level.SEVERE, null, ex);
        return null;
    }

Use Flash Controls without Flash

You can spend hours searching keywords concerning the use of
Flash UI controls -- including skinning via Styles -- outside of
Flex Builder. There are quite a few extensive, and helpful
postings. But I cannot find anything that helps with trying to use
those controls even outside of the context of Flash CS3.
Is there any way for those of us who cannot afford the
expensive development tools, to be able to build solutions -- just
using the SDK and the command line compilers -- that incorporate
those UI Components, or is this a purposeful product marketing
decision to only allow applications to be built incorporating those
controls if you license the IDE?

Nobody offered a suggestion though!
I have the same problem. Have chosen to disable it in YouTube because the HTML5 just won't load. It all looks good, sitting there waiting with the usual placeholder there, but when I click on it, nothing loads.

How to close a front panel using 'one button dialog'?

I wish i could use a 'one button dialog' so that the user can close the front panel when asked.
actually, i do put a 'open vi reference' followed by an 'invoke node' and then by a 'close reference' in a case true false (vi attached)
it seems that i can'ty use the option 'close FP' in my invoke node.
I am using a labview 6i version, is that possible to have this option, otherwise hoe can i achieve muy application without this invoke node??
thanks

How to Stop annoying error dialog

I am using bluetooth to connect my phone to the computer, but OVI suite always say that connectoivity error in the process of synchronization.
How can I told OVI suite to hide these minor error messages, as it always force me to click OK to these dialogs (usually more than one), before using it or shutdown the computer.

Hi ArShui, in next Nokia Ovi Suite version, under development at the moment, there will be improvements regarding these sync error messags.
Cheers, Samuli

Error I am getting is :
Invalid statement: "select >>sum_fxn<<(num_1,num_2),age from inputStream"
Description: Invalid call to function or constructor: sum_fxn
Cause: Probable causes are: Function name sum_fxn(int,int) provided is invalid, or arguments are of
the wrong type., or Error while handling member access to complex type. Constructor sum_fxn of type
sum_fxn not found. or Probable causes are: Function name sum_fxn(int,int) provided is invalid, or
arguments are of the wrong type., or Error while handling member access to complex type.
Constructor sum_fxn of type sum_fxn not found.
Action: Verify function or constructor for complex type exists, is not ambiguous, and has the correct
number of parameters.
I have made a user defined function in a java class and configured this function in the EPN assembly file under the processor tag.
But when i am trying to access the function in the config.xml file , it is giving me an error in the query.
Please provide urgent help that how to write the exact query.

Hi,
In the EPN Assembly file use
<bean class="com.bea.wlevs.example.FunctionCEP.TestFunction"/>
instead of
<bean>com.bea.wlevs.example.FunctionCEP.TestFunction</bean>

Error when using software update server

Whenever I try to point a non-managed client to use my software update service, I am getting this error;

Any ideas whats causing this?
The software update does not return an error if not using the unix console, it just shows no valid updates.

The reason why you are receiving is because you don't have the forward slash after the 8088.
Your current setup: http://fileserver.occmed.net:8088
Correct setup: http://fileserver.occmed.net:8088/
This will solve your problem.

How to "close" applications and not use data

Is it possible to "close" applications so to not use any data/internet at all, for example with safari?
Or is it when you click the "home" button, it closes?

Technically, yes.
All apps once activated remain techincally open but suspend themselves when navigated away from.
The email app however, lets say you go in, and it starts the manual checking of mail. If you leave it, it will continue with that check until done. Then stop (but check again if you set your mail settings to check on an interval).
Other apps, suspend themselves.
To add more (my opinon on things) read this post by me

How to handle the error when using Connection.setAutoCommit()

I use Jboss's datapool to realize the connection to Sybase
Database.And after connected to the database I wrote "con.setAutoCommit(false)" then the error occured.
The error is "java.sql.SQLException: JZ0SJ: Metadata accessor information was not found on this database. Please install the required tables as mention ed in the jConnect documentation."
I think it is because there is something wrong with the
configuration of the database but can not handle it .So please
help me,thank you!

help me,thank you!Most likely it means that your either DB or JDBC driver doesn't
support transactional approach, I mean: commit(), rollback() functions, so it reports setAutoCommit(false) as errorneous situation.

How to close a loaded testplan using C#-OPUI

Hello,
i created a OPUI in Cä that loads a testplan and executes it.
But i cant find a function to close an already opened testplan.
Means when i load testplan-1 it executes SeqFileLoad, the oi load tetsplan-2 and it execute SeqFileLoad.
But when i load again testplan-1 then it doesnt execute SeqFileLoad because it is still loaded.
So i am looging for an anload/close command.
Thanks for help

#1.
Are you looking to UnLoadAll Modules of a sequence file?
If so try: SequenceFile.UnloadModules
from TS help:
Return Value
Returns True if all modules were successfully unloaded. If any sequences in the file are executing when you call this method, the method returns False.
Purpose
Unloads the code modules from all steps in all sequences of the sequence file.
#2.
If you are looking to close the sequence file then maybe SequenceFileClosing Event can be helpful.
From TS help:
Syntax
ControlName_SequenceFileClosing ( file)
Purpose
Use this event when you need to perform cleanup or otherwise require a notification when the Application Manager control closes a sequence file. This event is generated immediately before the Application Manager control closes the file. The event handler for this event cannot cancel closing the file. Use the ApplicationMgr.QueryCloseSequenceFile event when you want an opportunity to cancel the closing of sequence files.
