Can I embed an aquired image in the front panel or does it have to be in its own window?

I need to be repeatedly displaying processed images and I know that I can make the image window "float" so that it is always on top and never becomes hidden when I click in the vi's front panel, but it is inconvenient that if I move the vi window or scroll within it, the image window stays where it is. I would like the image display to be a part of the front panel if that is possible, so that both move together.
Thanks

This is fairly simple to do.
I have attached Make IMAQ Child.vi, which is a slightly modified version of one I originally found on the NI website.
One required input is the filename of the parent VI, which can easily be obtained by using the "Current VI's Path" constant and Strip Path to remove the filename from the path.
The other required input is the IMAQ window number.
This will make the IMAQ window a child panel within the specified parent window. It will move with the parent window.

How can I simultaneously acquire and display an image on the front panel using a PCI-1424

Dear friends;
I want to use PCI-1424 , and labview 5.1 to capture the image, But I can not find some functions in labview to capture, display and save the image.Can you be kind to share some examples or provide some information.
Another question is how I CAN display the image in the front panel.
thanks so much

Hello yangshang,
Thank you for contacting National Instruments! To acquire images from the 1424 you will need NI IMAQ 2.5.1 or later. This can be found HERE on our drivers download page. One thing to note is that in LabVIEW 5 we only had the ability to view an IMAQ image as a pop up window. This VI is called "IMAQ Windraw". This will pop up a separate window that will display your picture. If you need to view the picture on the front panel you can try saving the image as a file (BMP, JPG, etc) then use the LabVIEW Graphics and Sound VI's to Read a picture file in and then wire the picture to a picture control on the front panel. Let me know if you have anymore questions. Good Luck.

How can I simultaneously acquire and display an image on the front panel using a PCI-1408

I have to acquire and display an image directely in the front panel of a *.vi using a PCI-1408. i have to know all informmations about this image because I want to create a calibration system.

Hi Paola,
if you own IMAQ Vision you can just have a look at the examples that comes with your board or you can look at: http://zone.ni.com/devzone/explprog.nsf/6c163603265406328625682a006ed37d/2abaefe05789961686256866007c0d22?OpenDocument.
Without IMAQ Vision look at:
http://zone.ni.com/devzone/explprog.nsf/6c163603265406328625682a006ed37d/22474456534202b086256aff005fc4f3
(or search at ni.com for "IMAQ Display without IMAQ Vison)
Please mail me if you need further help,

I want to save an image of the front panel, (with data), after every VI run

When I try to copy the front panel (using a select all), and paist to paint, all the data in the graphs show up as they did after the last run, but the data in the charts dissapear. The chart itself is copied but the data is not. Any ideas on how to solve this?
Thanks,
Brian

This Knowledgebase also has some information on programatically saving VI images
http://digital.ni.com/public.nsf/websearch/942DAA35C7B35616862565FE005F713F?OpenDocument
(KB 197BB7VJ if the link doesn't work).
Note that you don't have to put the code in the VI you are running in order to save it to a file, so you don't actually have to modify your VI. You can just run a seperate VI that uses the VI name from the first one (I've attached a VI which could either be run standalone or used as a SubVI, as well as an example of using it as a SubVI).
If you don't want to do it programatically you could just hit the print screen button on your keyboard and then paste it into paint and crop off the extra windows stuff.

How can I make a pdf-file of the front panel?

I like to make a pdf-file of the front panel. Thus I need a vi, where I can input the printer name (as the pdf-printer is not the default one), the vi and the name of the future pdf-file.
Thanks, Verena

Try this and if you were to search the forum with "pdf" as the search parameter, you'd find several postings on the same subject. One of them is here and another is here with some email addresses of individuals with existing toolkits.

Why cannot the block diagram view of a VI show the "connector pane" view in the UR corner, like the front panel view does?

Perhaps there is a good reason for this that I just haven't figured out. I haven't seen any questions about it searching the NI site, however.
But it just seems totally inconvenient to always have to go to the front panel to get to the connector pane view, especially if some of those connectors are hidden. Then I have to go to the block diagram, guess which control/indicator I want to unhide, go back to the FP to check it on the connector pane, then go back and hide it again, and repeat if necessary. Even if the C/I is visible on the FP, it's still an extra step or two.
When I'm building connections using the block diagrams and planning where to put connectors in subVIs so they would be easier to wire up (line up inputs/outputs on sides, not have to go top-to-bottom, etc.), it sure would be nice to be able to work totally in the block diagram realm.

Image of the front panel and block diagram

Hi,

It may not open properly, but that is okay.
Thanks,

How can a PowerPoint presentation be shown inside the front panel of a given application ?

I´m developing a application and I thought it would be a great idea if I could somehow show a PowerPoint presentation inside its front panel. Can it be done using LabVIEW active x vis or can´t it be done at all ?
Thanks in advance !!

Like I said, I tried that option (and even got it work somehow, by connecting nodes from other places and using type casts), but I don't think it can manage that in a real app.
After thinking about this some more, I've come to an unlikable conclusion - it's possible that there is no AX control for PP. Not for animation, anyway. If I remember correctly, when you open a PP presentation in Internet Explorer, you see the slides, but not the animation. If an AX control would exist, I'm sure IE would use it, which is why I think there probably isn't one.
You can get a presentation into an AX container very easily by choosing the third option (open from file). Then, if you select a PP presentation, it will open in the container. However, if I remember correctly, you have no properties and methods to control it, and I don't think it will show the animation, so it's a bit useless.
Maybe someone does know of a way...

I made a slideshow on iphoto and exported it to itunes. The original on iphoto seems to have changed (all on its own)! and I want to export the original back to iphoto so that i can burn it to a dvd. How do I export it back?!!

I recently made a slideshow and exported it to itunes. The original slideshow that is saved in iphoto has changed, all on it's own!! The photos are different and in a different order.....not sure how that has happened! However, the one on itunes is how it should be and I want to get it back into iphoto so that I can burn it onto a dvd. Can someone tell me how to get my slideshow back into iphoto from itunes please? And any ideas why my original in iphoto has changed?!!! Many thanks.

Can I draw lines or borders on the front panel of a VI ?

I would like to devide a VI into "visual sections" with lines or boxes around groups of controls and indicators.

You can use the decorations of LabVIEW, or programmatic the picture control.

Can i place controls from the properties dialog of an express vi on the front panel?

I'm using the spectral measurements express vi in my vi and I'd like to put the "window" and "number of averages" controls from the properties dialog on the front panel. However, there are not outputs on the express vi icon for these parameters. Can I place controls for these on the front panel somehow or do I always have to go into the block diagram and open the properties dialog to change the values?

The way to do this is to right click on the express VI and select Open Front Panel. This will convert it to a standard subVI. then go into the subVI and replace the Spectrum Averaging and Spectrum Window constants to front panel controls by right click on them. Right click the icon and select Show Connector. Wire the new controls to a free terminal on the connector. You may have to add additional terminals if there aren't any available to wire to the new controls.

How do I programmatically display jpeg files on the front panel

Hi,
I would like to be able to programmatically display various jpeg images on the front panel of a VI. I would mostly like to be able to display one image at a time and have the ability to programmatically change the image to different ones under program control. I found a picture indicator but not sure how to use if or if this is the best way. Thanks for any help.
Dave Adams

Yes, you can use a picture indicator.
The attached simple codelet shows how to display a jpeg image on it (Make sure the image indicator is big enough).
Let us know if you need help with the rest of the coding.

Leaving the front panel displayed on a subpanel after stopping

I have a tab control.
Each tab control has a subpanel.
Each subpanel has a static vi reference attached to it for launching.
I would like the image of the front panel displayed in the subpanel after the program has finished running so that any information that was displayed is still present.
Is there a way to retain all the settings between run's?

When you say settings, do you mean controls? If so, you can right click on them and select Data Operations >> Make Current Value Default. That will keep the settings initialized how ever you set them up.
I believe you can use use the Get Front Panel Image VI Method node, similar to the way to run the VI. You can create one by right clicking on the VI reference wire and selecting Method for VI Class >> Front Panel >> Get Image.
I've attached a code snippet of the node. If you want you can just drag the file into your block diagram and it should turn into code.

How to run a subVI without poping up normally, but when clicking a button, popup the front panel?

I know pop-up the front panel of a subVi when called by selecting VI Properties>>Windows apperence.
But what I need to do is: always run the SubVI inside the parent VI as the nornal subVI do without poping up. But when I click a button"show front panel", the SubVI popup the front panel.
Is there anyway to do this?
Thanks,

ossoo,
You can use a static VI reference to the subVI and then use the Front Panel Open invoke method to show the front panel when you want. I have attached two VIs that show this. I saved these VIs for LabVIEW 2009 so you should be able to open them up and run them in 2009 or later. Add.VI is the subVI that you are calling. The Caller.VI is just a While Loop that contiually calls the Add subVI. Inside of the While Loop is also a Case Structure with a Static VI Reference (you might need to change the path this is pointing to after downloading the VIs to your computer for this to work) and the Front Panel Open invoke method. You can run the Caller.VI and interact with the main Front Panel as normal and see the subVI but then you can click the Open subVI? boolean button and it will open the subVI's front panel. You can continue to interact with the main front panel and see the values update on the subVI's front panel as well. You can just close the subVI's front panel when you are done viewing it. Does this help?
