Labview style controls in VB

I'm developing an application in visual basic and I want to utilise some
fancier graphing controls as the MSChart control is not going to be
sufficient for my needs. I've had a look at a few National Instruments
packages, Measurement Studio and the now obsolete ComponentWorks but they
contain a lot of stuff that I don't need (eg. C++ classes) also the $2900
price tag has scared me off a bit. All I want is a graphing activex control
for VB6 that will handle real-time 2D plotting and has features such as
cursors, etc. built in. Does anyone have any suggestions on a good control
out there. I have Labview6i, is there a way to utilise its controls in VB6?
Thanks
Nick

I don't think you can use any of LabVIEW's controls directly in VB but you can call LabVIEW app's from VB
via ActiveX:

In LabVIEW, you could make a small simple VI that has just a chart on the front panel. Compile the VI into an EXE and enable ActiveX server. Then, in VB, you can call the LV ActiveX server and pass it data to plot on the chart.

Set default to Classic style control/indicator

Is it possible to set default to "classic style" control/indicator so that when I create a control/indicator from the block diagram, I will have a classic style control/indicator on the front panel?
Somehow, I still like the classic style control/indicator more. Many times, after I create a control/indicator from the block diagram, I have to replace the new style control/indicator with a classic style control/indicator from the front panel. It can be done, but it would be nice if I can create what I want from the block diagram directly.
Thanks.
Ian Ren

Well, to manually place a classic control, you would just go to the classic palette, no settings needed.
Have you read the detailed help for this option? Maybe it's not exactly what you think it is.

VI analyzer and dialog-style control.

When using VI analyzer it comes up with an occurance that states "The control labeled "whatever" is not a dialog-style control. Because of this, its appearance will not be platform-specific." What is the significance of this message and the pros and cons of not using controls from the system pallette.
Using LV 8.2 and TS 3.5
Using LabVIEW 2010SP1 and TestStand 4.5

Use the controls from the System palette when you want your UI to look like standard dialog UIs in your operating system. For analyzing any other kinds of VIs (test VIs, subVIs, instrument panel VIs, palette VIs, etc.), you should deselect this VI Analyzer test to reduce the amount of "noise" in your results.

I want to do a project in Labview which controls 5 light bulbs which lights in a room.

I want to do a project in Labview which controls 5 light bulbs which lights in a room. The switching on of light bulbs depend on amount of sunlight falling on a LDR. Small intensity of sunlight should cause the lighting of one bulb after the other. I need some help in writing my program in Labview.

LDR is a resistor whose resistance decreases with increasing incident light intensity... I know, you are already aware of what LDR is...!!
--> Well what exactly you want a LabVIEW program to do in this setup of yours...??
--> If you want LabVIEW to take control and lit different bulbs, based on the light intensity, I would like to know, how exactly you planned to measure the resistance variation of LDR??
--> What DAQ are you using??
--> Are you aware that DAQ cards can measure the voltage across a shunt resistance (here LDR) and indirectly tell you the variation in the resistant, provided a constant current passing through the resistance.

Need picture style control for photo and video wit...

Lumia 1020 stands for its excellent phone camera. But I am very disappointed with its JPG output. The whitle balance is always a big problem, then too much contrast and oversaturation. True, the photo is crystal sharp, but who needs a bad color photo with great sharpness?
After Lumia Black, the DNG format comes. Now I cannot shoot without it. So I just find the 1020 is really great, but the built-in processing destorys all.
I don't know about other phone camera, but just look at the iphone's. Thanks to its great overall JPG output quality, keep much more details, so people love to use post-fx apps in their phone to make good-looking photos. Then 1020 for me, I just have to live with the DNGs instead of easy sharing.
808 Pureview has all the picture style control funtion, even in video !! Down the contrast sharpness and saturation, then the semi-CineStyle is coming! Look at the 1020's video sample, it is a shame.
All I want to say is: Can you (I don't know to call Nokia or Microsoft) make some control opitions like 808 or just low down the over contrast/saturation/sharpness photo and video. I don't wanna see a such amazing sensor and lens camera like this terrible.

In very general terms, the requirements for Video will exceed those for Photoshop (PS). If you are looking at PrPro CS5, then the video card WILL make a difference, and PS CS5 now takes advantage of the video card, than before.
For PS, the minimum HDD setup would be a 2x system with physical (not partitions) HDD's. Video has more requirements in this area, and I would say that a 3x setup is the minimum. Do read Harm's linked article, as it is the best that I have ever run across.
For the PS setup, just locate the Scratch Disks for PS on your extra HDD's, the ones with your Project and PrPro Scratch Disks.
Enjoy the new computer, and welcome to the forum,

How to use LabView to control Primera Bravo II CD burner?

I am trying to use LabView to control the Primera Bravo II CD burner and label printer. The software that controls the Bravo II is PTPublisher. How to use LabView to communicate/control the PTPublisher? Please help, Thanks

Hi Qian,
I installed PTPublisher on a virtual machine, and I was wondering what kind of tasks you wanted to control within LabVIEW. From the program GUI, it appears like the only way to access functions is via mouse clicks. Do you know of any other way to control the Bravo II CD burner besides the PTPublisher software? If not, does the PTPublisher allow you to control it in some way other than clicking?

Use Labview to control two Picomotor actuators successively through Model 8753 iPico driver

Hello All,
I want to use Labview to control two Picomotor actuators(belong to channel A ,C) successively through Model 8753 iPico driver.Since the example VI's
(Application.vi) from Newport's website just control one actuator at one time, so I copied the example code, thus there are two repetitive sections (see the attachment) in
the while loop structure. The test result was that two Picomotor actuators moved to respective target position circularly. And I found the test was correct when two Picomotor actuators belonged to different address. Can anyone tell why ,what should I do? Any assistance with this matter is greatly appreciated.
Best Regards,

control two picomotor actuators.vi ‏90 KB

BRox,
I had a look at the examples and obviously all it does is to communicate to the drive through RS232 with a proprietary protocol. With the documentation in the block diagram and the documentation of the protocol it shouldn't be too hard to understand what's going on, but on the other side NewFocus has obviously missed a chance to provide a high level and easy to use API for their product...
I can't dive too deeply into the features of this drive, but before you spend too much time on understanding their command language, you should check with NewFocus, if it is possible at all to meet your requirements with their hardware. The main reason why I doubt that is the slow communication speed provided by RS232. The only way to reach a sinusoidal motion profile of 30 to 70 Hz with this type of communication is running the complete trajectory generation and interpolation onboard. If you have planned to generate the motion profile in LabVIEW and send setpoint commands to the drive this will probably not work.
If the drive provides another command input (e. g. an analog +/- 10 V input for torque or velocity command signals), we can talk about alternative approaches.

Using LabView to control a pump

I am a college student working on my senior project. My group is trying to use LabView to control two diaphragm pumps. We have a code written that generates the appropriate signal. The problem that we are having is getting this code to activate the pumps and make them run.
Any help would be appreciated.

You really need to provide more information.
What is the interface between the code and the pumps? How does the code communicate with the interface? Are all the necessary drivers loaded?
What happens, exactly, when you run the code? Do you get any error messages? What are they?
Please post your code along with answers to these questions. Also provide any other specific information which might be necessary for us to assist you. Good questions can get good answers. Vague questions will only get more questions!

Help Using Labview to control Kikusui power supply with a PIA4850 controller

HI I need some help using Labview to control 4 Kikusui power supplies. We have a PIA4850 Kikusui power supply controller. I can use the visa test panel and see the PIA4850 but can see any of the power supplies. I have very limited use of Labview and only wrote a couple programs using GPIB. The PIA4850 is a USB controller and can control up to 32 PS. I can get it to work with a Excel demo software that came with the controllers so I know that it is working. Any help will be appreciated. I am using LabView 8.2 and have updated to the Ni-DAQ 9.0. I have a program that I need to incorporate the PIA4850 into once I figure out how to operate it. Thanks in advance.

HI and thanks for the help. I did get one power supply to work but have another problem. I need to control 4 power supplies at the same time and can only operate the one that is addressed N5!C1. If I set the other to N6!C1 and so on I get an error stating
“Error -1074135008 occurred at ki4800_2 Configure Voltage Level.vi Possible reason(s):IVI Error in the method "get_Item" in the component "Kikusui4800". E_IVI_UNKNOWN_CHANNEL_NAME: Unknown channel name (N6!C1)”
I am assuming that I should be able to change the node number and that will change the supply that I need to use. Everything works great if I use N5!C1 I can change any of the supplies to address 5 and can control it with no problem. I can even have multiple supplies with the same address N5!C1 (don’t think I should do that) and change them all at once. I need independent control of each supply.
I am in a pinch here and need to figure it out but could use some help. Any ideas will be greatly appreciated.
Thanks

Scripting Style Control Grid Size

Is there scripting functions, to allow me to edit a VI's alignment grid size, and control style for creating controls/indicators? These setting are saved in each VI under the VI Properties, under the Editor Options. I looked around and couldn't find them. Thanks.

LabView serial control

Hello,
I'm currently trying to use LabView for RS-232
communication. The thing is, instead of using
the standard hardware flow control method, I'd
like to be able to control the flow control lines
manually. Is there any way to set the values of
these pins?
Thanks,
M

Before you buy.

VISA will let you do this. There is a bit of a learning curve, it's
slightly more complicated than the standard serial port VI's but a whole lot
easier than using In/Out port. Once you learn to conform to the standard
style then it actually makes your diagrams straightforward and data-centric.
Also VISA is platform independent, at least it works fine on Win9x/NT. I
have had some trouble with Win3.11 though.

Labview Numeric control integration with C++

Hello all,
I am trying to use a Numeric control called "Meter" from labview in my
C++ application. I am able to load the Numeric Control called "Knob"
from the insert actvieX control option in VC++ but i am not able load
Numeric control called "Meter" which looks like a car speed meter. Can
any help!!
Thanks

If you are inserting these as ActiveX objects, these aren't the LV
controls, but those of another NI product, Measurement Studio. I
believe that you can go to the properties of the knob and change its
display style to look like the meter.
If this doesn't work, you might want to post to the other mailing list
specific to MS.
