Opening an existing vi

You load a VI into memory by selecting File>>Open . In the Choose the VI to open dialog box that appears, navigate to the VI you want to open.

The VIs you edit in this course are located in the C:\Exercises\LabVIEW Basics I directory.

As the VI loads, a status dialog box similar to might appear.

The Loading section lists the subVIs of the VI as they are loaded into memory. Number Loaded is the number of subVIs loaded into memory so far. You can cancel the load at any time by clicking the Stop button.

If LabVIEW cannot immediately locate a subVI, it begins searching through all directories specified by the VI Search Path . You can edit the VI Search Path by selecting Tools>>Options and selecting Paths from the top pull-down menu. The Searching section lists directories or VIs as LabVIEW searches through them. You can haveLabVIEW ignore a subVI by clicking the Ignore SubVI button, or you can click the Browse button to search for the missing subVI.

Saving vis

Select Save , Save As , Save All , or Save with Options from the File menu to save VIs as individual files or group several VIs together and save them in a VI library. VIlibrary files end with the extension .llb . National Instruments recommends that you save VIs as individual files, organized in directories,especially if multiple developers are working on the same project.

LabVIEW uses the native file dialog boxes so they act similar to other applications on the computer. You candisable this feature by selecting Tools>>Options and selecting Miscellaneous from the top pull-down menu. If you disable native file dialogs, LabVIEW uses its ownplatform-independent file dialog boxes with some convenient features, such as providing a list of recent paths andreducing the steps necessary to save VIs in VI libraries.

Moving vis across platforms

You can transfer VIs from one platform to another, such as from Mac OS to Windows. LabVIEW automatically translates andrecompiles the VIs on the new platform.

Because VIs are files, you can use any file transfer method or utility to move VIs between platforms. You can port VIsover networks using FTP, Z or XModem protocols, or similar utilities. Such network transfers eliminate the need foradditional file translation software. If you port VIs using magnetic media, such as floppy disks or a moveable externalhard drive, you need a generic file transfer utility program, such as the following:

  • ( Windows ) MacDisk and TransferPro transfer Mac OS files to the PC format and vice versa.
  • ( Mac OS ) DOS Mounter, MacLink, and Apple File Exchange convert PC files to the Mac OS formatand vice versa.
  • ( Sun ) PC File System (PCFS) converts PC files to the Sun format and vice versa.
Certain operating system-specific VIs are not portable between platforms, such as DDE (Dynamic Data Exchange) VIs,ActiveX VIs, and AppleEvents.

Refer to the Porting and Localizing LabVIEW VIs Application Note, available by selecting Help>>Search the LabVIEW Bookshelf , for more information about porting VIs.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
