API calculation time expired or recording clock ticks
Is there an API available in LabWindows to memorize the graduations or calculating time expired?
It is necessary to use with a do while loop. I want to perform an action repeatedly to 260milliseconds in a while loop and then get out of the while loop 260 milliseconds once is in place.
What is the best way to go about this?
According to the precision you expect from calendar, you can move the solution most simple timer () to the more complex calls of SDI APIs.
The simplest solution (anything but needs CVI):
tini double;
tini = Timer ();
While (timer() - tini)< 0.26)="">
doSometing ();
}
Advanced solution are the use of () QueryPerformanceCounter and QueryPerformanceFrequency functions SDK (). Here you will find an interesting discussion thereon. This solution involves the use of the Windows SDK available in the full versions of the CVI.
This code should work fine:
#include
void yourFunction (LARGE_INTEGER t) {} BOOLEAN error; error = QueryPerformanceCounter (&tini);) return; } doSomething (); } while (1); return;
Delta LARGE_INTEGER to tini, tn,
If (! error) {}
Error in manage somehow
{}
error = QueryPerformanceCounter (&tn);)
Delta. QuadPart = tn. QuadPart - said. QuadPart;
If (delta. LowPart > = t.LowPart)
break;
}

We have all seen the old clock rotation expression where you create a rotation of the second hand and then tie the minute hand to the rotation with an expression while he moves to 1/60th speed to simulate the minutes and seconds right?
I am creating something similar but with a clock "Ticking" like a timex watch on the second hand so it ticks along. Tick, tick, tick, tick instead of smooth rotation. I discovered that the use of this expression related to the rotation:
var tick = time * 6;
Math.Floor (Tick)
But what I want to do now is to have the tick of the minute hand (separate layer) more than 6 degrees every minute. In other words, he holds 59 seconds and then jumps 6 degrees in 1 second.
I can't understand this part. Any ideas?
Thank you
Jim
I would like to do this way:
second hand
Math.Floor (time) * 6
minute hand
Math.Floor (time/60) * 6

Clock tick slow, erratic in Windows guest OS
I have two problems that significantly affect my use of VMWare. I am running Workstation ACE edition v6.0.5 - 109488
hosted on an HP system with plug Dual Core AMD Athlon 64 X 2 5600 + 2,81 ghz 2.87 gb ram. The host operating system is XP pro x 64 SP2 v2003.
I have a number of virtual machines on this x 64 system and they all have problems, I will describe and I have similar VMs on two
other systems, an XP pro SP2 on a 32-bit laptop and W2k system, also 32-bit and these virtual machines do NOT have these problems.
The problems are:
(1) to start the computer virtual, for a period of several minutes, just type in the VM (caps startmenu, passwords, back/netware guests)
is repeated one or more times. Meaning if I have an XP virtual machine and the password of the connection box is open and I type a character which
character is repeated one or more times, usually 5 to 10 times. It is essentially impossible to type until the problem
clears up on its own, it does after letting the VM sit for about 5 minutes.
(2) all the virtual machines on this x 64 exhibit erratic clock tick as the host. Tick its second click of observation with the windows date cmdlet
clock hand and also other applications that display the second time, I see the second count occur very quickly (i.e.
faster than one per second) and also very slowly (a second socket to 4 seconds of wall). As I have what I can observe
See counting the seconds speed upward, slowly down, sometimes appear normal (although normal never lasts very long).
I see this on all my virtual machines (NT, XP, XP, Vista, netware), but they all perform more or less acceptable than the second count. However
my Vista VMs are dog slow and my test season a relationship between the slow clock and poor performance. A Windows 2008 VM shows a slow clock, but the beat of clock rate does not vary and is acceptable error. Virtual machines are configured to run on a single processor.
Note that I usually run 3 VMs at the same time. A novell VM server, a windows NT4 VM and a test VM, which is generally
XP or vista. The novell and NT4 VMs host print services and email and are usually do nothing but idle.
I studied this problem of clock and found all sorts of news and changes of parameters in config.ini and .vmx file, but
None of these things has made an observable difference.
I remember reading about an AMD Dual Core Optimizer utility that allows to synchronize the time between carrots stamp counters. Maybe this will help? Visit the website of AMD...

get time expired error in labview while getting screenshots
Hello
I need to capture a screen shot for Agilent Spectrum Analyzer, series of ESA. But everytime I run the program I always get time expired before the operation is complete. I enclose the program and also captures screenshots of the program. If anyone can fix this, I'd be very happy.
Thank you all the...

Hi all
I found the solution... Add MEMMEL function at the end... And time bet two screenshot must be more than 10 minutes, and then it gives current screenshot...

Hello
The BMC watchdog is only intended to be used in conjunction with the OpenManage Server Administrator. It uses one of the OMSA DSM services for heart rate. If you have never installed OMSA so I don't know how the BMC watchdog has been activated. It is possible to configure a monitoring utility via IPMI, or someone may have inadvertently turned it on IPMI commands.
You can install OpenManage Server Administrator Managed Node and go to system > properties > auto-recovery. If you set this option to none, then it should turn off the BMC watchdog. If it is already set to none then set another option, apply, back to zero and then apply again.
If you enable the watchdog of BMC and OMSA must be installed and running on the system. If you decide to uninstall OMSA then you must disable the BMC watchdog first by assigning None.
Thank you

How can you stop the toolbar of 'charm' of popping up all the time and this HUGE clock
How can you stop the toolbar of 'charm' of popping up all the time and this HUGE clock... I am new to windows 8 and I do not... I much prefer to have windows 7 return... any suggestions?
I preached this whole week... my pleasure to increased win8 x 100 once I turned off the edge of the touchpad scan function. The path may be slightly different, but the synaptics touchpad is the Control Panel / hardware and audio / mouse / device settings / settings / edge shot - and disable "enable edge scans".
This prevents context changes maddening when browsing the web or doing anything on the touch pad really... you can always access the charms on the right upper or lower, and you can always access history FRO the top left corner after that you disable this... but it is much more controlled.hope this helps -

But you can ora_rowscn pseudo-column and scn_to_timestamp the user function to get the time when the table was modified last:Scott@my11g SQL>select scn_to_timestamp(max(ora_rowscn)) lstmod from t1; LSTMOD --------------------------------------------------------------------------- 13-DEC-10 05.05.22.000000000 PM Scott@my11g SQL>update t1 set val='stuff' where id=1; 1 row updated.

But I'm not wheither it is reliable to be used on the production database.

problem when-validate-point and when-timer-expired...
Hello
In the when-validate-agenda of an item, there is the piece of code:
Start
h: = create_timer ('mon_timer', 1, no_repeat);
end;
and in the when-timer-expired in the block of the form:
Start
....
set_block_property ('Blockname', default_where, 'id =' |:cust.id);
go_block ('cxs');
do_key ('execute_query');
....
end;
The code above in when-timer-expired is not executed... I mean the go_block and run the query {at least I do not see the query results in the cxs block}...!
But if I change the piece of code...
set_block_property ('Blockname', default_where, 'id =' |:cust.id);
x: = show_alert (...);
go_block ('cxs');
do_key ('execute_query');
then the piece of code in WTE is carried out as planned...
What may be the cause...?
I use forms 6i with patch 12 and db 10 g v.2
Thank you
SIMHmm. Maybe try a SYNCHRONIZE after the GO_BLOCK.

I recently reinstalled windows 8.1 and started from scratch with firefox. My clock of the computer somehow obtained a day before in the process, so all my browsers gave me errors. I fixed the date and all other browsers are fine, but Firefox still gives me "this connection is not approved - user certificate has expired" whenever it tries to load a site https (even google).
I tried to erase everything in Firefox, up to and including completely uninstall and reinstall and it is still giving me these errors, fresh out of the installer, with the time / the correct date on the clock. Help?
Edit to add: good... so I put my clock forward a new day, and the errors went away (for firefox, they returned in other browsers). And then I put it back again, and mistakes had disappeared, but only on sites that I visited while the clock was wrong. I guess that this imposes a kind of site by site reset or something? I still want to know what caused it, however, so I don't have to change the date of my computer whenever I visit a new https: site in firefox.
Edit 2: and... I have to go and do again for each site every time I close and re-open firefox.
If you haven't already done so, could you try to rename the Firefox certificate store file, cert8.db, so a new startup of Firefox? Here's how:
Open the settings folder (AKA Firefox profile) current Firefox help
- button "3-bar" menu > "?" button > troubleshooting information
- (menu bar) Help > troubleshooting information
- type or paste everything: in the address bar and press Enter
In the first table of the page, click on the view file"" button. This should launch a new window that lists the various settings files.
Leave this window open, switch back to Firefox and output, either:
- "3-bar" menu button > button "power".
- (menu bar) File > Exit
Break while Firefox finishing his cleaning, then rename cert8.db to something like cert8.old (Note: If your Windows does not display the .db extension, you can enable the display of file extensions using the steps described in this article: http://windows.microsoft.com/en-us/wi.../show-hide-file-name-extensions)
Launch Firefox back up again. You can visit most normally secure sites?

Favorite random, one at a time, change the records?
My problem started with the previous version of Firefox, and continues with the version 26.0. My HP Compaq dc7800p convertible runs THAT XP Pro 2002 with Service Pack 3 installed.
I'm going to look for a particular bookmark, and it will not be in the right folder. I need to find all of my other bookmark folders until I found and then bring it back in the right folder. This problem occurs only with a bookmark both and about once a week. So far, it has never been the same bookmark, still another.
Here are three examples:
(1) a bookmark for filmjunk.com, which is normally under "podcasts", was under my "local" folder I have access to FilmJunk several times a week.
(2) an article I wanted to read more later from AMC.com, which I placed in a 'general' folder, found under the 'games '. The article has been bookmarked about 30 days before my deciding to read the article.
(3) a bookmark for citizens Bank filed in 'Betsy', but was found in a folder for my school "ECC." This last bookmark that I hadn't used in over a year!I have reset Firefox several times, re - import favorites to Internet Explorer 8. Each time, after a day or two, the problem starts again. There seems to be no correlation between when I used last specific bookmarks and where or even if I initially placed them.
-waka_Flocka_flame,
Thanks for the quick response.
I'll try your second suggestion first, "problems of fixing with bookmarks."
On this page, under 'Difficulty the bookmarks file' help, I don't have the box 'Read only' ticked, so that the article did not help with my problem. Instead, I'll try the section directly below titled 'create a new file to bookmarks '.
Given that the problem came back after a few days, I will update with the results soon.
Thank you once again.

The large paintings of calculation time
Dear friends, dear LabVIEW developers,
I'm trying to reduce the time of calculation for large bays. (In real life I'm eliminating unimportant vertices of a 3D mesh.)
Migration from 8.6 to 2011 already has done a great job for me. And also I am pleased to run Windows 7 on a 64-bit computer.
But, imagine a pointer-oriented language where you'd change an array element, you do not expect the computing time to change with the actual length of the table.
Here, I work on a wide range of groups of array of length may be different (rather short, containing the indexes of the neighbors of my vertex).
My problem is that I really don't see the reason why (I'm happy) the 100 times more slow performance when having a 100 times more great picture at hand for the fair value of the Exchange.
Suggestions to work around to get the speed of the large paintings those comparable to small is greatly appreciated.
Kind regards
Jannis
PS: I tried DataValueReferences but just the computing time to get 1 million references is almost an hour.
Thank you guys!
You were very good!
Steven and Ben worked have been my brand of test bench has been poorly implemented, which Ben explained perfectly. This test has sent me the ghost hunting awaits the delay time for the large windows in the wrong place - the structure in Place.
My next mistake was my local chaos with different versions LV and 3 PCs: Altenbach and Jeff are of course right about to maintain the constant size of matrix comes mark reduction in a separate meter. I did this at a time in a lost version later - and not a not spot the difference of between ArraySubset and DeleteFromArray the icon for a while...
My time holes had to be hidden somewhere else. Thanks Ben, unfortunately those black dots of BufferAllocation are a bit small for my old eyes. Not know them at the end of the event and while loops!
Each 15 seconds I actually shorten the big picture at its actual size to display it in the 3D graph. Now, here's the little interesting: ArraySubset actually redirect the memory at the end of the event and while loops, while DeleteFromArray only! I don't know who wrote somewhere, just not where easily see you...
And to make it really bad: this allowance is probably made with each loop run little matter what this case has done - slowing of all stocks with it. (By the way: everything as a mem alloc comes even inside a case that is not running!)
Once again thank you all. For me it's back to work after a very long-term wild-goose chase.

Problem I have TO solve with the query: PREV calculation to the current record
Hi all
My version of db:
Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production
I have the problem to solve with a request (MUST BE a SELECT statement), but I do not understand how... I tried with the analytical function but... not just:
I have this table:
rownum KEY1 KEY2 A3 PERC IMP 1 A123 RISCP 01/01/2014 10 100 2 A123 RISCP 02/01/2014 11 100 3 A123 RISCP 03/01/2014 15 100 Application of expected result:
RESULTS KEY1 KEY2 A3 PERC IMP 90 A123 RISCP 01/01/2014 10 100 80.1 A123 RISCP 02/01/2014 11 100 68.085 A123 RISCP 03/01/2014 15 100 Starts recording with rownum 1 (the lower date with the same KEY) I do: imp - (100 imp * perc), where imp = 100 and PERC = 10, so the first result of the calculation is: 90
Now I have to go to record 2, so I do 90 - 11%: imp - (100 imp * perc), where imp = 90 and PERC = 11, results is 80.1
Now I have to go to the 3d recording, so I 80.1 - 15%: imp - (100 imp * perc), where imp = 80.1 and perc = 15, results is 68 085
So I have to use the previous to the current PERC.
I'm sure it's possible through a combination of funcion analytical!
Thanks to anyone who can help me!

How can I animate various mouse Tracker points at the same time during a recording?
Hey,.
I'm trying to animate my character so that his left arm cross out his right elbow, and then the fear character and she jumps on the side. I can't animate the arms at the same time in a single record. How can I animate various mouse Tracker points at the same time?
Playing right now I seem to be only able to animate a point Tracker of mouse at the same time (i.e. his right arm) and when I return to 're-save' so I can animated left arm, right arm recording is saved on and now only point left mouse Tracker.
Hope that makes sense, let me know if you need me to develop. Thank you.
Currently, you'll want to separate Tracker mouse behaviors for each hand. Select the puppet in the project Panel, and then add the second behavior mouse Tracker via the add behavior button ("+") in the properties panel. Then, during recording, make sure to disarm one of them so that other behaviors can control the hand that you drag. We are studying ways to improve this workflow for future versions overview.
