Green digitalized lines form when Screensaver is on

Every time the screensaver comes on (a photo album), these green digitalized lines come on, and I cant get them to stop. Any advice?

Thanks everyone for offering your thoughts. I have put it through a round of testing today and found that indeed the green lines appear when I'm taxing my system with Photoshop.
Now my issue lies in what to do - get a video card or purchase a used Mac Pro of a similar vintage. Found a good deal on Craigslist for $400: 2.66GHz Quad Core XEON, 8 GB's of RAM, 500 GB hard drive, Nvidia 1024MB video card. I could stuff it with my other 3 hard drives and get a better card than mine (perhaps add that second display I've been wishing for). Opting for a new MacPro isn't an option, it's too expensive and I'd like to get another 2 years out of my 'system', generally speaking.

Multiple VI's using different digital lines in one VI.

I have created multiple vi's, each of which require either reading or wroting to a different digital line on the CB-68LP board. I need to put them all in one individual vi so that I can see everything on the front panel. When I have tried this the vi seems to send a confused signal and operate things which it shouldn't.
Is it even possible to try and do what I am doing? If not, any ideas what I can do? Thanks.

Multiple VIs are usually the better approach. What I would suggest is parallel loops. These are loops which do not have any data dependency on each other. One handles the User Interface - the front panel where you "see everything." Another which reads and writes from/to the digital lines. Maybe even a third which processes the data. Exchange data among the loops with queues or functional globals.
Keep a record of the state of all the digital lines. When something is to be written to certain lines, use either a Write Line.VI ( I don't recall the exact name) or use AND and OR functions with masks to protect the states of line you do not want to change.
BTW, the CB-68LP is merely a connection interface, not the digital I/O baord itself.

Help: Can you use software trigger on a digital line.

Hi:
We have a legacy DAQCARDard 700 which does not support hardware triggering.
We have a trigger from our instrument that is 5 V+ and we would like to
trigger when it drops to 0 V. We have several questions.
1. Do we need to invert the signal in MAX or is that only for V that are
negative?
2. Is there a good example in the examples where the state of this digital
line is used to trigger an analog acquisition? When we tried using the
digital trigger examples, we had an error saying that the hardware did not
support that mode.
3. We have an analog software trigger mode (based on the Analog Software
Trigger example) working which we would like to modify over to read the
digital line, but we have done very little wi
th digital I/O.
4. The digital trigger has been assigned a virtual channel of dtrg.
Any help would be much appreciated.
Thanks in advance,
Pete

Thanks Doug,
If we read the digital line instead of as an analog line would it improve
the accuracy of the triggering. Everything works now except we have a
little bit of timing jitter within about 1 data point scanning at 50 kHz.
However, I've never done any digital i/o with LabView, but may I should work
through some of the tutorials. If you thought that this might solve the
jitter problem. Would checking the state of the digital line allow a faster
response with softtrig, I guess is my question?

Green/Red Line Appears on .mov when exporting

Hi,
There's a green/red line that appears on the RIGHT SIDE when I export my presentation to QT. I'm using H.264 @ 24fps with Multipass encoding at best quality. I'm not including audio or transparency.
The slide size is 355x200.
The contents are vector graphics, images, and videos.
However, no videos are right justified.
I'm using KN 3.0.1 Trial and have QT Pro & Flip4Mac Trial installed.
What are the reasons for this line in the .mov and how do I fix them?
Is it the shadow effect on the actual slide canvas?
I've exported files successfully in the last week since I've had my MacBookPro.

PCI 6602:How can I use the digital lines of the board and in the same time to generate pulse train using a counter?

Hello!
My problem appeared when I tried to update my code from Traditional NI-DAQ Legacy to DAQmx.
I am using 2 counters (counter 5 and counter 7) from PCI-6602, to generate pulse train, and also the Digital I/O lines of the port 0 (the lines form 0 to 7). What I do in my application is that I am starting to generate the pulse train on the output of the 2 counters, and after that I am playing with the state of the digital lines.
In traditional there was no problem using the counters and the digital lines in the same time, everything was going perfectly, but in DAQmx this is not possible.
What happens: I start to generate pulse train on the output of the counters, no errors encountered, but when I try to modify the state of one line of the digital port the generation of the pulse train is stopped. This is happening when I start the task associated to the digital port.
My question is: it is possible to create a channel on the digital lines without altered the channels created for the counters?
Another thing what I manage to see using the "Measurement & Automation Explorer" and Test panels for PCI-6602, basically is the same thing, I generate pulse train on the output of the counter 7 and try to start a task on the digital line, but I get one error :
"Error -200022 occurred at Test Panel
Possible Reason(s):
Measurements: Resource requested by this task has already been reserved by a different task.
Device: Dev4
Terminal: PFI8"
Instead if I use the counter 0 or counter 1 to generate pulse train I don't encounter the same problem.
Which resources are used by the counters 2 to 7 from the PCI-6602 board and the counters 0 and 1 do not use?
Thank in advance for any replies!

Hello Jordan, thank you for your reply.
I am sorry but I can not see or run your example, I don't use LabView, I use Visual C++ for developing.
Here is the code for generating the pulse train:
GeneratePulseTrain(unsigned long ulCount1, unsigned long ulCount2)
    short nStatus = 0;
    nStatus = DAQmxCreateTask("",&m_taskHandle);
    nStatus = DAQmxCreateCOPulseChanTicks (m_taskHandle, "Dev4/count5", "", NULL, DAQmx_Val_Low, 0.0, ulCount1,ulCount2);
    if( bTriggerMode == true) // if hardware trigger is enabled
       nStatus = DAQmxSetTrigAttribute (m_taskHandle, DAQmx_ArmStartTrig_Type, DAQmx_Val_DigEdge);
       nStatus = DAQmxSetTrigAttribute (m_taskHandle, DAQmx_DigEdge_ArmStartTrig_Edge, DAQmx_Val_Rising);
       nStatus = DAQmxSetTrigAttribute (m_taskHandle, DAQmx_DigEdge_ArmStartTrig_Src,"Dev4/PFI17" );
   //set the internal timebase
   nStatus = DAQmxSetCOCtrTimebaseSrc(m_taskHandle,"Dev4/count5","20MHzTimeBase" );
   nStatus = DAQmxStartTask(m_taskHandle);
    return nStatus;
And the code where I try to set the digital line:
SetChannelState(short nState)
    short nStatus = 0;
    uInt8 wrtBuf0[1]={0};
    nStatus = DAQmxCreateTask("",&m_taskHandle);
    // Configure line as output
    nStatus = DAQmxCreateDOChan (m_taskHandle, "Dev4/port0/line0", "", DAQmx_Val_ChanPerLine);
nStatus = DAQmxStartTask(m_taskHandle);
    wrtBuf0[0] = nState;
    nStatus =DAQmxWriteDigitalLines (m_taskHandle, 1, 0, 0, DAQmx_Val_GroupByScanNumber , wrtBuf0, NULL, NULL);
    nStatus = DAQmxWaitUntilTaskDone(m_taskHandle,10);
    nStatus = DAQmxStopTask(m_taskHandle);
    nStatus = DAQmxClearTask(m_taskHandle);
    m_taskHandle = 0;
    return nStatus;

How does one write to individual digital lines accross many DIO-96 ports?

I want to be able to write to any individual DIO-96 line without having to repeatedly init. The available vi's can set up only 24 lines at a time. If it is desired to write to a line outside of those 24, another 24 lines must be initialized, then to return to the first 24 lines, those must be initialized once again. Very clumsy! Does anyone know how to init all lines one time and then allow random access to all 96 lines without further initialization?
Thanks,
CBD

Hi Tom,
try to use (or at least to insert) that control in another environment (like a Visual Basic form) in order to check if it's working properly. Also, check if you have the DLL with the same name in your system folder - this control it's just a simpler way to use that dll.
You can use Write to Digital Line.VI, but pay attention to ITERATION terminal - if it is 0(default) LV will call DIO Port Config (find details in help).
Hope I understood the problem...

I grasp that you are having an issue with the display but if you adjust the position of the display it disappears.
Here is a link to Display Quality Issues that may help.
As you stated it goes away when you reposition the display the connection cable may have become loose or damaged from opening and closing the display.
Here is a link to the HP Pavilion 14 Notebook PC, HP Pavilion 14 Touchsmart Notebook PC, HP Pavilion 14 Touchsmart Ultrabo.... Chapter 4 page 36 has removal instructions that may assist you in checking for that problem.

Green vertical line

Hi there
A green vertical line has now appeared on the screen of my MacBook Pro 13inch and won't go away, even after restarting.
Does anyone know what this is? How do I get rid of it?
Is the problem covered by AppleCare?
Thanks

I don't think there is anything you can do for it at home. That indicates a probelm with the display itself, its cabling, or the video chipset.
About the only thing you can do is diagnostic, not curative. Attach an external monitor and see it the line persists. If it goes away on the external, then the probelm is probably limited to the display or its cabing. If it persists, the probelm is likely in the video chipset. None of these problems are easy for an end-user to address unless you are skilled as working with tiny parts and have the proper tools and troubleshooting guides.
As long has the computer has ot suffered physical damage, this is exactly the sort of thing that makes AppleCare worthwhile. I'd take it to Apple as soon as feasible.
NOTE: Turn the computer off and let it get to room temperature. Turn it on again and see if the line is there at cold starting or appears later. If it appears later it could be heat-related and you need to tell the Apple tech that when you take it in. He'll have to let it run long enough for the problem to show itself to get e peoper diagnosis.

Green scan lines on some of my photos...

So i was out hiking and took some selfies. And some of my photos from my front facing camera has green scan lines on it. It looks like an effect almost. But only on some of the photos does it have this on there. I have no other camera or photo edit apps other than the apple camera. It stinks too because the only ones with the lines on it were my favorite photos. Right after taking the photo nothing seemed out of the ordinary. The little thumbnail was not green. But later when i got home to upload them, my 3 best selfies are green. Like a night vision camera green, with scan lines on it. Oh I'm on a 4s, iOS 7

They are still there when i deleted the bg, the first appeared when I used free transform to scale an image on another document. I then went to start again on a new page and the blank document had these lines.
So i reset my photoshop settings and it stopped happening to new documents however some of my older documents still had them on.
Also I wasn't using any layer masks or feathers on the document when I first noticed the lines.
I'm using Adobe cc 2014

Auto Calculate Forms when opening pdf

I have a PDF that has form boxes that I created in them. I also have an Access Database that is pushing values to these forms. The numbers are populating all of the cells correctly. My issue is that when I open my file some of the form boxes that rely on other form boxes are not calculated when I open the PDF. I need to manually go into the field, delete the number in the box, hit enter, then the number is calculated. Is there any way that I could calculate my forms when I first open?

How are you populating the fields from the Access database, exactly?
In any case, you can use the calculatNow document method to update. Just place the following line of code in a document-level JavaScript, outside of a function definition:
// Update the calculated fields
calculateNow();

Can I tell Acrobat where to automatically create forms when scanning in many of the same document?

The automatic form creator isnt very good at recognizing where I want text forms when I scan in this particular paper form. I have lots of these paper forms that look the same and am trying to convert each of them into a editable digital copy. Is there a way to help acrobat know where i want the text forms to be on the following scans without manually making the text forms everytime?

No, but you can:
- Use a script to create the fields in pre-defined locations
- Create them once and then copy them over (Ctrl+C, Ctrl+V) to over files
- Create them once and then use the Replace Pages function to other files.

Digital lines showing in full quality quicktime export

Hello - just an addition to a previous matter - I exported an 11 min. movie in H.264, w/the default settings, NTSC 4:3; 720 x 480. It's 572.1 MB and I burned to a CD, so that the client can download it into their own laptop, then project it onto a screen. When I viewed it on my computer, there were all kinds of 'digital lines' that showed up, particularly through the transitions (though on most everything else as well), that don't show up on the burned DVD copy. I'm wondering what, if any, particular settings can I use when exporting, so that these pesky 'lines' won't show up, as it looks perfect on the DVD, but won't be viewing from that on the day of the event - ok, thank you!

I have the same problem... Im using DV pal. Looks loke this is a big problem for many users, bus nobudy knows how to fiks it..my lines are still there on the dvds to by the way..)

Arming a counter polling a digital line

For arming a counter, a start trigger on the STC counter can be roughly emulated by polling a digital line and arming the counter once a high digital pulse is sensed. How can i do that?
I'm using a PCI-MIO-16E-4

Daniel,
You did not mention which programming environment you are using, so I will describe the structure in LabVIEW (no matter which language you are using, this should give you the general idea).
1. Configure your DIO port with DIO Port Config.vi.
2. Configure your counter operation (Counter Group Config.vi, etc.).
3. In a while loop, call DIO Port Read.vi.
4. Monitor the bit corresponding to your trigger line. When this bit goes high, stop the while loop.
5. Immediately after the while loop, call Counter Control.vi to arm your counter.
This should be the basic structure of your program. Good luck with your application.

How to make fields required in an updateble multi line form?

How to make fields required in an updateble multi line form?

You need to create a validation item that is triggered when the user clicks the submit button.
Set the validation type to "Function Returning Error Text".
Then add your validation into the "Validation Expression 1" field. Something like:
BEGIN
FOR I IN 1.. HTMLDB_APPLICATION.G_F02.COUNT LOOP
IF HTMLDB_APPLICATION.G_F02(I) IS NULL THEN
RETURN 'Please enter in a value for xxxxx on line ' || TO_CHAR(I,'0');
END IF;
END LOOP;
RETURN NULL;
END;
As long as the function returns a string, an error is generated - as there is no single field where this error can be displayed, it will need to be displayed "On Error Page".
If the return value is NULL, then the fields are valid and the submit process can continue.
