Iterating over the controls

Hi, I'm new here and new Flex3, but really like what I've learned so far.

But I encountered a problem. How do you iterate controls/components? In VB.net, you should do something like:

For each myControl as control in Me.Controls
"do things here
Next

I tried to watch using containers / canvas as a container for travel, but I can't understand how in fact a loop through the controls - it's for a simple text validation feature. Everything seems to point to the ' For Each... in ' statement, but... I'm stuck.

Thanks in advance

Two unexpected local variable when iterating over the array of containers.

Hello

I have to iterate over an array of containers. In the ForEach loop step variables format, I've defined two variables; It is common, second is the current item.

The loop works very well.

However, during the process of debugging, I spotted two new variables inhabitants called the __ElementSibling0 (type: number) and __ForEachReleaser0 (type: reference obj) created in silence by TS as soon as I start the iteration on my table. What is?

They exist because:
1. I iterate over an array of containers, or
2. I use the _currentElement_Freq variable, or
3. It's always like that?
Those that are used by the implementation to each step. You can see them only because you have enabled the setting display the properties hidden.

You can safely ignore their presence.

Iterating over the elements specific to the screen (web page)
Hi guys and girls,

I feel stupid for not being able to solve myself, so I'm glad to know that there a wealth of experience and talent to help...

My question is this:
I have a web page (screen) full of items of different types, for example
.. /Web:IMG[@ALT='Enable update "or @index = '26']
.. [/ 'web:img[@alt='Details or @index = ' 25']
.. [/ web:td[@text='Ongoing' or @index = '62']
etc.

I want to find the img and then iterate over their index. Iterate no problem.

However: can one tell me how to identify images and bring them into a list?
Something like a ' for each element e; If e is an img; {do something}

Your help is appreciated.

Rgds,

If you want to delete objects whose attribute value null, use code with the following previous code
```
for(int count =0, i = count; i< images.size();i++){
          if(images.get(i).getAttribute("alt") == null ){
               images.remove(i);
               i=count;
          }
          else{
               count++;

          }
     }
```
Note: Here also alt with the attribute that you want to change

C7280 - cannot scan. Error message indicates another program has control over the device

I open the HP Device Manager to do a scan. I accepted the parameters and the scanning started. But the part passing through the analysis, I stopped the scan that I realized that I wanted to change the resolution. I leave the Manager device and rebooted but when I did, I got to tell an error message:

'Cannot perform the function you have requested because another program has control over ice dev'.

I have nothing else open and so I can't work on what program has control over the printer.

C7280 Prtinter. Mac OS x 10.7.

The Device Manager has not been updated for Lion and there is still no specific Lion software for your printer.

So far, you have the choice of scanning with picture Capture or preview. I'm sorry.

Hello

·          Were there any changes made to the computer until the problem occurred?

·          Have you tried right click and check the context Menu?

·          This happens for any particular folder?

Step 1:

You can check if the same thing happens in a new user account. To create a new user account

Analog control over the timing of myRIO MSP?

Hello

I'm new to myRIO and just got my.

How do you set the rate for similar samples of the port of an MSP myRIO?

For example, I would like an analog stream output 200ksps.

Place the block of OUTPUT ANALOG in a timed loop and runs only gives an output of 6.3 kHz frequency. (measured at the ao1 using a scope)

See the attached file.

I incorrectly use the timed loop? (.. .havent used before)

Or myRIO does needs some extra configuration?

Thanks for any help to what appears to be a very simple problem.

See you soon.

Hey, Carloman.

In this case the speed is limited by the software (OS, background process and especially the code LabVIEW) running on the ARM processor on the myRIO. 200 Ksps specification is for the hardware. If you need to write this young, you can use LabVIEW FPGA to write data.

One of the reasons why it is difficult to reach the 200 Ksps output rate of the side RT is because each iteration of the loop produces only 1 sample (the FPGA is configured for the only point of exit... a sample at a time). The perfect way to generate samples on the side RT and to write data to 200 Ksps is to build several samples each loop and use a FPGA personality that supports analog output buffer in memory. This allows to generate N samples each iteration of the loop and then send samples to a FPGA (FIFO) buffer that implements buffer and copy the data. I believe that it is coming in a future update.

For now, you can implement this architecture by creating a custom FPGA personality or you could do everything in LV FPGA.

Let us know if that makes sense.

Thank you!

How a TableView can iterate over the lines and get the cells?

I need to iterate over all rows in a TableView without using events. I would like to get the total number of lines, TableRow and a cell of a TableColumn specified in the TableRow.

Something like this:

for(TableRow tableRow: tableView.getRows()){
    Cell cell = tableRow.getColumn(4).getCell();
    // do something to the cell 
}

Is this possible?

Published by: Conzar on May 19, 2013 23:18

However, the problem with the checkbox has been resolved so I don't need to iterate over the lines longer.

Yes, don't use do not research to manage this is a much better solution, I just gave my search for a solution based on because you asked an iterative solution.

Below (research) code produces no output.

It works for me, I've included an example of executable, so you can try it.

My guess is that you are not taking into account the fact that the research is just a glimpse of the cells of the table at a time in time.
If you do a search for cell before show you the table on a stage, he's not coming back what it is because the cells are generated only on an as needed basis, and there is no need to generate all the cells before displaying the table on a stage.

I get the following output on Win7 Java8b89:

Scattered all over the hard drive downloads

Trying to gain some control over the download process; I always put Firefox 'always ask me where to save files. For the first half of the life of FF that worked perfectly well. Save a file that is brought to the top of the corresponding dialog box, showing the location that I lasted sauvΘs and asking if I wanted to re-use that one.

I can see how that might be a concern of privacy on a shared computer, such as the list of recently used files that comes with so many applications, but it has never been a concern for me.

What bug the absolute $% & % $& % hell out of me is that FF now appears most goddawful of random places as suggestions. No matter hoe, I always use the same folder, FF suggests places that are literally everywhere in the hard disk without detectable rhyme or reason. I waited patiently for the development team correct everything they did to make FF cannot perform this simple operation he was quite able to reach with an apparent ease at least as far as his Phoenix days. But, alas, the output ' Let's Break everything "of the week schedule has never solved the problem.

What gives? Someone at - it a fix for the problem? I know that there are affecting a lot of people just longer because I have heard the complaints.

I added the Boolean preference. I wasn't sure if she would take effect without rebooting or not. Of course, I had not too long to wait... Crash-O-Matic pulled on plan and gave him the restart that he may or may not have needed.

I used some time now and have not had the problem again. I will temporarily call this one resolved.

Thank you, man. You can't imagine how crazy this thing driving me for how long.

Some iPhoto albums appear empty with no sticker and say '0' when I fly over the album, but the photos are there when I double click.

To start, I read in countless discussions here on iPhoto glitches and patches, so I hope I'm not repeating this question, but I couldn't find the answer anywhere I had a question after question with iPhoto (mainly around several accidents after organizing photos into albums that made the album organization and this issue I describe below) and is considering moving to Adobe Bridge just to have a reliable place to store my photos without worrying about the constant pain. I realize that no program is immune to glitches, but the volume and the frequency that I've had with iPhoto is unmatched (which led me to wonder if it is just a user error, but I honestly can't understand for the life of me). So I describe my current number below, in the hope of resolving the issue so that either A. I can fix and give iPhoto a chance more or B can I ensure that my photos are safe and intact before transfer to another program.

Some of my iPhoto albums appear empty with no sticker and say '0' when I fly over the album, but the photos are there when I open the album. I have rebuilt the thumbnails, and it has not solved the problem. After the other issues that I had with iPhoto crashes, I made sure that all updates have been installed. Unfortunately, I don't remember if I've rebuilt or repaired the database, but it seems that all my photos are present, all mixed together and some showing in the albums 'empty '. Here's my question: is one problem, other than being boring? And should I switch to another program, or have I missed something?

A few details:

• I have rebuilt thumbnails today and it took 5.5 hours. It seems completing without problem, but has not solved the problem.

• I have my computer fully backed up on an external drive to Seagate drive as Mac OS extended (journaled) as well as iPhoto backed up separately on the drive as well.

• Looks like I have a "library" and "alias."

• I use iPhoto to organize my photos. I use Photoshop to edit. I love the feel of iPhoto, but I lost hours and hours trying to organize and solve problems.

• I use iPhoto 11 version 9.4.3 OSX 10.8.5 / / MacBook Pro processor 2.9 GHz Intel Core i7 Memory 8 GB 1600 MHz DDR3

More worrying is the issue of the repeated questions. How you use iPhoto and Photoshop together?

Tabula Rasa:

Download iPhoto Library Manager and use its function of reconstruction. (In early versions of the Library Manager, this is the file-> control Rebuild. In versions later it is under the menu library.)

This will create a completely new library. It will then copy (or try) your photos and all associated metadata and versions to this library and as close as possible to what you had in the damaged library fix it. It does this based on the information it finds in the iPhoto sharing mechanism - but it means that things not shared won't be there, so no slide shows, books or calendars, for example - but it should recover all your events, albums and keywords, faces and places.

Because this process creates a completely new library and does not change your old, it is non-destructive, and if you are not satisfied with the result, you can simply go back to your old.

The control of several Instruments: read parameter and continuous dynamic update

Hello

I'm trying to control three instruments using LabVIEW. My DC power and generating function are connected to the computer with a GPIB/ENET 1000 while my scope is connected via the USB port. I am currently having the scope to take a reading for each iteration of the while loop and have the event handler if there are changes to the power settings. I went by respective examples of the instrument and came with the attached VI. I wondered for some time on an installation where you connect continuously and are able to modify settings dynamically; It's my first crack at it.

The idea is to expand this VI by logging the reads in a text file, by automating a sweep from 1 K - 1 MHz and taking averages of this sweep to chart in Excel. For now, I need to get down the basic and I'm constantly freezes when I run the VI. Sometimes it runs without problem, but begins to freeze when I try to set the DC supply voltage and other times it freezes right from the start. I wonder if it has to do with the placement of the read scope; before and after the handler but I can't test the theory now that I'm away from the laboratory.

Would appreciate any advice you can give,

Yusif,

Yes, the steps could be taken in a parallel loop. If this loop will be completely independent (don't share data or control with the other loop), it should be simple. If you do not need to pass data between the loops, you might well be better to learn the architecture of producer/consumer because youwould has essentially re - invent.

Is there a way to detect the mouse during the event for the controls within a tab control?

I need to change the mouse pointer when it moves on controls that are found in the tabs.

Now when the mouse passes over the tab, LABVIEW does not detect the saperately of controls for the mouse over event.

Is there a way to do what I intend to do?

Your problem is with the Panel.Controls [] property. It does not return the controls that are inside containers (tables, tabs, groups) and returns only the container itself. As illustrated by Sam, if you want the references to the controls in the tab, you must get the references to the pages and get the controls on each page and add them to your original table and do this recursively.

You can either write a VI to do this (or search for it. There was posted here screw that analyzes recursively the FP for all control references) or everything just statically for this control a tab and move. There is also a VI delivered with LV that can help you with this, but I suggest that you not use, because it will be difficult to operate if you generate an EXE file.

And I also recommend the Tool of Capture of Code.

How to make the difference between the mouse down events in the control of the chain (click on contour vs click Center)?

Hello

I have a control over the chain on my UI and I would like to make the difference between mouse different events, that is to say, to be able to differentiate a click on the outline or the label of the controller vs right-clicking on the Center (between the control in "edit" mode)

The reason is that sometimes if the user does click not in the Center but in the scope of control, Labview fires the mouse event down but the typed keys are not registered...

Is it possible to distinguish the two?

Thanks a lot for your help

Set the string "update as you type" and use instead a "changed value" event Now, the event fires whenever a new character is entered.

Get an entry appears in the control panel

Sorry, but I am very new to Labview

I have a vi. There are a number that I need to fix for this vi, but the only way I can adjust the number opens on the front panel. How can I put the entries in the first vi. I want to be able to put the number on the face before first rather than the second front panel

Thanks for any help.

Step 1... Read tutorials there are many links on the forums that their

Step 2. Create a Subvi

Step 3. Right-click on the icon subVIs (in the upper right corner of the front panel of this sub - VI) and choose show connectors

Step 4. Click the connector that you want, and then click Control

step 5. Save the VI

Step 6. Drop the VI on your upper-level block diagram (that you want to set the control of)

step 7. Hover over the Subvi you come to fall and you see a 'node '.

step 8. Right-click on the node, and then choose create control

step 9. SURPRISE YOURSELF!
