Has anyone called the Solver dll in Labview?

I have developed a non-linear mathematical model in Excel that uses it's Solver routine. I am currently trying to convert this over into the Labview environment because the equations are more manageable and the front panel interface is more marketable. However, I need the power of the Solver dll.
Frontline Systems (www.solver.com) provides an evaluation version of the dll but I am new to this and I was wondering if anyone has done it and could provide a VI which calls this dll or has any suggestions, please?
I think it would be pretty nifty if Labview could provide this sort of optimisation power. (It's current optimisation routines in the Mathematics toolbox are pretty limited and are not nearly as powerful as Solver)
. But I'm sure a labview guru could configure a simple VI which calls the Solver dll for a multi-dimensional non-linear problems similar to Excel....
Many thanks in anticipation!!!

Hello �
You might want to consider using a Call Library Function Node. This node supports a large number of data types and calling conventions. You can use it to call functions in most standard and custom-made DLLs and shared libraries.
Refer to the Configuring the Call Library Function Node section of Chapter 2, Shared Libraries (DLLs), of the Using External Code in LabVIEW manual (attached) for more information about using the Call Library Node to call code from text-based programming languages.
Hope this helps!

Has anyone used the NAG libraries with LabVIEW?

I try to get the "g08cgc" (chi-square calculation) running, but LabVIEW hangs up everytime I start the VI..
Some tipps ... ?

Here is the code (wirtten with LV7.1)
Let me say that I'm a newbie using statistical functions and calculations.....
For the calculation of Chi-square I have the followind input variables:
- measured values
- calculated values
- coefficients
If you/someone can give me some tips how to calculate chi-square with this input variables it would be very helpfull (e.g. maybe MS-Excel can do this,too ?! Using .NET etc?)
Thanks in advance!

Calling 64-bit dll from labview 8.2 on Windows7

Hello,
I have tried the LABview driver from the OMNIDRIVER (OceanOptics) package. But when calling functions from the “OmniDriver32.dll” , LABView is crashing and says that the memory is corrupted.
I am using LABVIEW 8.2 (32-bit) running on Windows 7 (64-bit). I have tried some LABView code examples given for LABview 7.1 and 8.0. These example are using the OmniDriver32.dll (not the OmniDriver64.dll).
But maybe these example are assuming that you are on a 32-bit operating system, which is not my case.
So I have tried calling the OmniDriver64.dll. but LABView seems not to recognised the dll and can’t read the included functions.
Is there a way to call some 64-bit dll from LABview 8.2 ?
Or do I need to buy a new license for LABVIEW 64-bit ?
Thanks,
Pierre

There is no virtualization support for DLL bitness issues outside of the Windows standard directories. The Windows and System directories that an application "sees" depends on its bitness. All other directories are not mapped depending on the calling process' bitness.
So if you have installed 32 Bit LabVIEW and are not calling one of the system DLLs, you have to point the path of the DLL to the real 32 bit DLL. Pointing it to a 64 bit DLL should not even be able to get the VI compilable, since Windows will refuse to load the DLL into the 32 bit process as being an unknown file format, and that should make the VI broken.
If you need to call a system DLL you simply enter the DLL name without path and Windows will find the according DLL for LabVIEW.

This sounds like a virus or malware program that has made its way onto your computer. I would ensure you have the latest virus definitions on your computer and run a thorough (complete) scan of your system. If this doesn't work, I would suggest you use Microsoft's Malware Removal Tool. You can download it at the link below. Hope this helps.

Has anyone used the QuickUSB module (Bitswise Systems) to interface to a USB Camera via IMAQ for USB?

Has anyone used the QuickUSB module made by Bitwise Systems with LabVIEW for image acquisition. I have a USB camera and I'm trying to use the IMAQ for USB controls to no avail. Any input is appreciated.

Are you using the NI-IMAQ for USB functions or are you calling the QuickUSB libraries from LabVIEW? Unless the USB camera is DirectShow compliant, then it will not work with the NI-IMAQ for USB driver. You can use the Code Interface Node in LabVIEW to call external dll's, and it looks like from QuickUSB's website that is the best way to go. Hope this helps.

Has anyone tried the new MS Oracle DataProvider ?

Hi all.
Has anyone tried the Microsoft issued Oracle .Net data provider? I am not fond of switching horses in midstream (have been struggling with ODP for a few weeks). I do not like the ODP for these reasons...
1) Documentation is really non-existant/useless especially where hueristics and 'gotchas' are concerned
2) it is a HUGE install (why I have no idea)
3) some things simply do not work (like my recent rants on trying to return varchar2's from stored procs and functions).
Is the MS any better ?
Thanks

Hi,
1) There is a pdf doc and integrated help which comes with the ODP.NET. There are a few gotchas which could cause some hair-pulling moments. Sometimes it helps to read the same doc several times to really know what to do.
But instead of wasting time reading the doc, the samples cover most of the typical cases. (i think it includes your varchar2 output bind case).
2) The huge install is due to Oracle Client 9. The provider needs several dlls beyond Oracle.DataAccess.dll and OraOps9.dll. There are some other oracle standard dependencies also. MS provider for oracle will have the same issue (I think they need oracle client install also).
There a few post where the `Instant client install` is going to solve that.
But the thin client (like JDBC thin driver for oracle) is still (IMHO) the best solution for the huge install problem.
3) See my reply in the other post. (try the sample also)
Finally, which some other posters have mentioned before: Good luck looking for help for MS's provider when you are stuck.

Has anyone used the mackeeper software?

Has anyone used the mackeeper software?

Short answer: I don't recommend it, but it's not "a scam" or malware, per se. If you use it, you may have some real performance issues.
Me: I was an actual MacKeeper user (paid version) for about two years. What follows is my experience and conclusions. I am not a paid reviewer, nor tech professional. I am an educator with about 15 years of experience using Macs. I am what most people would call a "prosumer," in that I know a good deal about my systerm, but am not a techie, anti-utility software zealot, etc. I have no affiliation with Zeobit (manufacturer of MacKeeper) nor any of its competitors.
I bought MacKeeper in 2011, and then upgraded last year. I used it to remove junk files and duplicates, and experimented with the anti-virus software. I didn't use most of the other features.
The problem: I am running a 2009 15" Macbook Pro 2.8GHZ Core 2 Duo, 4GB RAM, 512GB HDD. Over the past year, it has been having major performance issues. Slowdowns, hangups, applications quitting and more were all becoming the norm. I deleted duplicate files and ran MacKeeper a few times a month. I also ran permissions repairs regularly (disk utility). I looked for the cause of the slowdowns everywhere, from too many user accounts being open, to resource hogs. I decided that MacKeeper's Anti-Virus software was just taking up too much RAM and CPU, so I disabled it. I continued experiencing slowdowns and started monitoring my available RAM with a freeware app called Memory Clean. It often reported that I had less than 500MB available, even with very light usage, application wise. After "cleaning" memory, I could get my available RAM to about 1.5GB, max. I struggled with these issues for a year or more, and was about ready to concede defeat and buy a new machine. I figured my MBP was over four years old, and perhaps running Mountain Lion and normal wear/tear were just too much.
This morning, I noticed that the biggest resource hog on my system was a process called "MacKeeper Helper." The process relaunches even when it is forced to quit. It was consuming over 100MB of RAM and up to 99 percent of my CPU at times! I also noticed a process called "anti-virus" that also could not be quit, and was consuming over 100MB of RAM itself. I started researching how to kill these processes, and was introduced the the Great Online MacKeeper Controversy. Here is what I learned:
Some in the Mac community have pure hatred for this product (and some hate all like it).
There were numerous user reports of it slowing down systems
Zeobit seemed to be guilty of questionable ethics, particularly in its advertising.
There was no way to stop MacKeeper Helper and Anti-Virus processes from running with deleting the entire application.
I wasn't the only one annoyed by MacKeeper's system pop-ups, trying to sell me something I already bought.
The software got good professional reviews, even from well-respected publications (e.g. MacWorld)
It is often confused with Mac Defender, which WAS malware. They two are not associated.
The Decision: After researching ways of fully uninstalling MacKeeper (and considering whether or not I should), I decided to try the uninstall instructions from the manufacturer. It said that it would remove ALL traces of the application. I also didn't want to get into too much Terminal work and manually deleting things, as some users suggested doing. I followed the process (close app, drag to trash, enter password, click "uninstall"). I then ran a permissions repair and restarted.
The Results: I have been MacKeeper-free for about an hour as I write this. Put simply, my problems appear to be completely solved. MacKeeper Helper and Anti-Virus are gone. Available RAM is now up to 2.75GB. I have experienced no slowdowns or app crashes. Even bootup appeared to be considerably faster. Launching iPhoto with thousands of images now takes a few seconds instead of minutes. Everything feels faster. It's like I have my Mac back! I was ready to admit defeat and dish out another $2500+ that I didn't have. I now think that won't be necessary!
What Should Yo Do? You'll find a lot of controversy out there between professional reviews, ethically dubious paid reviews, Zeobit's own defense through public statements, and Mac users themselves. Some users like it, and swear up and down they are real people. Others are extremely angry and hate the product with the passion of 1,000 burning suns. All I can do is tell you my experience and make the following statement:
The bottom line is that I would not install MacKeeper/buy MacKeeper on my Mac. After investigating my own system's problems (which made iit nearly unusable) and concluding that MacKeeper might be the issue, I uninstalled it. Magically, all my issues went away. So...I report, you decide. Best of luck.

Has Anyone gotten the HP USB Tunner (KS523AA) to work on a Sandy Bridge Laptop (DV7-4290us)

Just Wondering what the heck the deal is. I have two older DV7s that do work with their TV Tuner But this new one is driving me nuts. I also noticed that it appears HP has changed MediaSmart in that on the two older laptops the module/program that is used to watch/record live TV is called MediaSmart Live TV. On this new laptop the Module appears to be MediaSmart Movies and TV. So I was also wondering if anyone with a Windows 7 Home Premium has gotten the MediaSmart Movies and TV program to work with the KS523AA tuner.
Since this is one of the Sandy Bridge laptops (with the Intel Chip problem I may end up returning the entire laptop) so has anyone gotten the KS523AA working on either a DV7-4280us or an Envy 17-1190NR
Thank You

Has anyone got the QT stand alone installer to work?

OK, Has anyone got the QT stand alone installer to work that has a problem getting IT6 to work also?
You can look at my original thread and see what I've been through: http://discussions.apple.com/thread.jspa?threadID=262511&tstart=0
and now am stuck with an old version of QT and no version of IT! Can't update iPod, can't do crap. How slow can Apple be to fixing whatever bug is in IT6?! It's obvious that alot of people are having trouble and many of us are having the exact same or similar problems. Apparently a call to support is no help.
Mark

I didget QT stand alone to install. I had the error -3 message. I unistalled itunes and quicktime. Then I reinstalled using my orginal ipod disc. I then was asked to upgrade to ipod 6 or something. Which I did. Still got the error -3. Then I got the QT stand alone to install by it self and every thing works great now. There was some thing stating if I wanted to "Unistall QT for windows" I said yes. There were some error associated with removing "QT for Windows" during the install but after that it works great. It took something like 20 min. for it to download when it took itunes only 7 min. to download earlier.

Sounds like you have a battry issue but don't want to believe it.
If a car was running fine on one tank of gas, then you filled it up with another tank of gas and it began to run funny, one might suspect that tank of gas. But let's just say coincidence blew a valve-- would you think the new tank of gas was the culprit?
BUT WAIT!! It just might have been! The gas could have been of higher octane and put more more strain on the valves; you know, like going from 87 octane (OS6) to 93 octane (OS7) and showing you the engine was on the edge of compromise.
Sometimes you have to go with common sense. If everything else is ruled out, it must be the battery. And if it runs fine one moment in OS6 but immediately ***** in OS7, I'd believe my battery was suspect-- though comfy-- in OS6 but the OS7 showed its true power.
Moreover, if you had the answer-- or didn't want to believe someone's more competent advice-- why did you even call? You've already shown that you don't know much when you asked if you could go backwards after setting up the new OS as a new phone.
Additonally, if you're such the know-it-all, but yourself the $29 battery and put it in yourself. It's a piece of cake.

Has anyone received the new update for the X6?

has anyone received the new update for the X6 with the updated browser? what is the firmware version?
Greece Nokia X6 RM-559 v40.0.002

I agree with Vinimutta!!
*slide to unlock with digital clock & sms & missed call notification
*support for homescreeen widgets
*qwerty keypad in portrait mode
every single update so far was pathetic attemp to fool us and make us happy.
there is no change at all from v30,31, and 32. exect the slightly smaller font for text input in v32.
nokia promises alot in the new update, (browser, smiler and map)
hope it leaves up to the expectation and include the portrait qwerty,homescreen and lockscreen.
Why is it so hard to implement?
slide to unlock and homescreen is already available in c6, and the portrait qwerty is available in 5800.
its no like we are asking for impossible like continuous autofocus for video recording!!
