How would I embed NetMeeting in Labview 6i using ActiveX?

I would like to use my USB Webcam through netmeeting to run in Labview.I initially wanted to use a Java Applet and looked at Webcam 32 but I thought a cheaper option would be to use ActiveX. I would also like to be able to use netmeetings controls. I have been trying to figure out a way for a while but I am easily confused with Labview!

The original question is from a month ago but hopefully this will be helpful still to you.
You can definitely control NetMeeting using ActiveX and LabVIEW. All you need is to have NetMeeting and its ActiveX control installed on your machine. Then use the following method to get the NetMeeting controls on your LabVIEW VI Front Panel.
1. Place an ActiveX Container on the Front Panel (Controls Palette >> ActiveX >> Container)
2. Right click inside of the container and select Insert ActiveX Object...
3. Select from the list the ActiveX Control named NetMeeting.
The container will then have an instance of NetMeeting in the ActiveX container. I followed these exact steps above and created this VI which is just a NetMeeting control i
n an ActiveX container.
Hopefully this information is helpful. I created the example in LabVIEW 6i.

How would I go about adding multiple rectangles using the same lines of code?

How would I go about adding multiple rectangles using the same lines of code? I would prefer to just run through a set of code every time I need a polygon. If I just have to create multiple polygon adding statements that's fine but I'd prefer just 1.

>>How would I go about adding multiple rectangles using the same lines of code?
You could create a method that creates and returns x number of Rectangle elements:
public IEnumerable<Rectangle> CreateRectangles(int numberOfRectsToCreate)
for (int i = 0; i < numberOfRectsToCreate; ++i)
Rectangle rect = new Rectangle();
rect.Fill = Brushes.Blue;
rect.Width = 100;
rect.Height = 100;
yield return rect;
..and then call this method from anywhere in your code:
IEnumerable<Rectangle> rects = CreateRectangles(5);
foreach (Rectangle rect in rects)
//add to StackPanel or do whatever with the Rectangle elements:
yourStackPanel.Children.Add(rect);
>>If I just have to create multiple polygon adding statements that's fine but I'd prefer just 1.
When adding Point objects to a Polygon you can only add one per call to the Add method but you could call the Add method inside a loop, e.g:
for(int i = 0; i < 10; ++i)
//add to StackPanel or do whatever with the Rectangle elements:
Polygon p = new Polygon();
p.Points.Add(new Point());

How do you create a pdf file by using ActiveX?

Is there a way that you could use activeX to write the data into pdf file? If so, do you have to have Adobe Writer install?
thank

hello
you could generate a report using the report - VIs (gives you opportunity to add headers, footers, tables etc.) and print the report to a PDF - Printer (e.g. FreePDF). No ActiveX or Adobe Writer needed.

How would this code look in LabVIEW?

Hello,
I am new to LabVIEW and I'm hoping that someone can tell me what the code would look like in LabVIEW if I want to do the following.....
I am using a C dll that has the "acq_get_board_count()" function and so far I am able to get that to work, however I'm having issues with passing the array of clusters from LabVIEW to the C dll
short count , code;
MyStruct_board_info *board_info_list;
count = acq_get_board_count();
if (count){board_info_list = new MyStruct_board_info[count];
code = acq_get_board_info(count, board_info_list);
}else{// no interface card installed}*******************************************************************************
my C structure looks like the following:
struct MyStruct_board_info
char name[32];
short type;
char en_first_gain;
long first_gain_min;
char computer_ctrl;
char pad[3];

One trick I found is to right-click the call library function node and select "create .c file" and examine what it will create. I used the method that nathand used to generate the cluster using array to cluster to embed the array contents as values. After you build the array of clusters, I think you will have to pass in element zero. If you pass in the whole array and look at the c-code, it will still embed a 4-byte size field in the struct and this will whack your dll.
Use adapt to type in your call library function node. The pictured code generates the following c-code:
/* Call Library source file */#include "extcode.h"/* Typedefs */typedef struct { double Array0;double Array1; double Array2;double Array3; double Array4;double Array5; double Array6;double Array7; double Array8;double Array9; double Array10;double Array11; double Array12;double Array13; double Array14;double Array15; double Array16;double Array17; double Array18;double Array19; double Array20;double Array21; double Array22;double Array23; double Array24;double Array25; double Array26;double Array27; double Array28;double Array29; double Array30;double Array31; } TD2;typedef struct { TD2 Array;
uint32_t Numeric;
} TD1;void CIELChToDE94(TD1 *arg1);

How can I edit data in Microsoft access using ActiveX

I've tried to modify Read Access DB with ActiveX to edit an entry in my database, but I get the following error
Exception occured in DAO.Field, Update or CancelUpdate without AddNew or Edit..

Did you try to do the same thing in LabVIEW (the same order, after you have the right reference to the recordset). I know this kind of problem from VB too. I didn't try it in LV but I supposed it should be the same.
Let me know if it doesn't work.

Summary with associated fields - How would I do this?

Post Author: mikebres
CA Forum: General
I have a group that summarizes the Maximum Date/Time from several operations for that day, showing the last DT within that group. Essentially showing the time the plant finished the days run for each operation group. I would like to be able to also show the Operation Number and the Machine Number that is associated with that maximum DT on the Summary line next to the Maximum DT. How would I do that? I'm using v8.5.
ThanksMike

How to pass parameters to an XSL for use in a transform (JSP/XSLT)?

I have an XSL: style.xsl
I have an XML: data.xml
I want to do an XSL Transform on data.xml, using style.xsl, with parameter
Language=en
With Saxon you would do:
saxon data.xml style.xsl Language=en
But how would I do this with WL6.x, using the JSP XSLT tag:
<x:xslt [xml="uri of XML file"]
[media="media type to determine stylesheet"]
[stylesheet="uri of stylesheet"]
<x:xml>In-line XML goes here
</x:xml>
<x:stylesheet [media="media type to determine stylesheet"]
[uri="uri of stylesheet"]
</x:stylesheet>
</x:xslt>
Thanks
Alain Jacquot

There is currently no way to do this from the jsp xslt tag. I have filed an
issue because this is available in the JAXP 1.1 API. If you need this
functionality in the current version you will need to use the JAXP API
directly.

How do I embed bitmaps into a built (.exe) LabVIEW application?

I am trying to embedd bitmap images (icons) into the exe file of a built LabVIEW application. I tried it, and got them in a "data" folder. I want everything in the .exe file, you know, just like C/C++ or just about any other programming language.
If anyone has any tips, I would be grateful.
I know about embedding the images in the controls, but that is not my goal. I need images as files to be embedded, somehow, into the .exe. The reason is I am using the picture control to read the images, but they are static once they are read. If it is possible for the picture controls to somehow retrieve the images from some other source, that would work also.
Otherwise, if someone knows how to dynamicall
y embed bitmap or other images into buttons in an array, that would be useful as well.
Thanks

Actually, many C and C++ programs, like LV itself have folders of data
that aren't linked into their code. But, if that is what you are
looking for, one pretty easy way is to load the images into memory and
place them into a 2D array of data, a string etc. Make an array of
these and make the value default. At runtime, you can now skip the file
I/O, or you can write the data to a temporary on launch and read them
back whenever you like.

When I call an external program from Labview, how can I embed the interface into the front panel?

I'm running Labiew 6i for Linux. I'm using a system exec.vi to call an external program to do image manipulation (since there is no IMAQ for linux). How can I embed the user interface of the external program into the front panel of Labview?

As far as I know, the only way to embed other GUIs in LabView is an ActiveX in a container.
As long as you are using Linux, try to place (moving them on the desktop ) the two windows linked (like those 3 of WinAmp).

How would I interface an instrument with a serial UART output to LabVIEW?

I am trying to gather some information on a upcoming project. I have a instrument that outputs a serial UART stream. I would like to interface this with LabView. This is the product that I am planning to interface with. http://www.pressureprofile.com/products-digitacts.php I am just learning how to use LabView so this is all new to me, any help would be greatly appreciated.

First- I would recommend takinga look into the Basic serial read and write example that ships with LabVIEW. Second, RTFM (Read The Friendly Manual) for the device. A Google search for serial comms will provide a reasonable backround for how serial comms can be configured.
As to how to implement the specific serial protocol in LabVIEW-- well, use a VISA call to the serial port to configure the various properties of the VISA ser:instr class and IF you learn the equipment's expected settings and what, and when, it responds, the "nuts-and-bolts" of wiring your device driver becomes reasonably simple.

How would one communicate with a custom I/O card under Win 2000 and Labview?

Hypothetically speaking, if I were to develop a custom prototyping PCI card interface using addresses 300 to 303, what would be involved in getting LabVIEW to communicate with this prototyping card? What issues may be important in the development of the prototype card itself?

Hi Robert,
NI-VISA offers you the ability access the hardware directly.
Issues?
Speed, I believe this is not the fastest way to get at the registers.
Determinism, if your device will require the CPU get back to it on a regular basis, Windows could get in the way.
Just the thoughts that come to mind. I hope this helps,

How can I embed a HTML document onto my webpage?

What I am trying to do: I am trying to make an image that has links to urls from different parts of the image.
What I have done so far: I have built a photoshop image to embed on my webpage, following the instructions offered by many online forums, but cannot actually embed it as it isn't a url.
Firstly, I sliced up an image, adding url's and alt tage etc to each slice. Then I did:
File > Save for web > (Prest: JPEG High) > Save > (entered my file name) Format: HTML and Iamges > Save
When I locate my file where I saved it, it has been saved as a Chrome HTML Document, but I can't then embed this on my website, using the 'embed code' tool I normally use. I presume this is because it doesn't begin with http:// ?
Here is the HTML document I have made: file:///C:/Users/Daniel/Desktop/UK%20map%20interactive/Afternoon/UK-map-locations.html
(If you can see this) This is the image I want and the links are working too but it's getting this onto an existing webpage.
Other pages I have seen have talked about iamge maps, but I take it using the slice tool is better for what I am trying to acheive?
Any suggestions/help would be greatly appreciated.

One: Users can't see links on your local desktop. You would have to upload the files somewhere. Two: Images generally don't contain links. URLs are meta information build around the image in HTML. Three: Because of the previous point, whether you use sliced images or an image map doesn't matter, if you have no way of inserting the information into the native HTML structure of the web pages. If at all, you would open the HTML file in a suitable editor like Dreamweaver (or even a basic text editor) and copy&paste it into the web page sourcve code, but you'd still have to upload the image(s). The rest we can't know. You have not provided any link to the web site or told us which hosting provider you use. From your description it sounds like one of those "free" providers that restrict user's options to customize to the bare minimum and the rest is based on templates and plastered with advertising. In any case, the solution is not in Photoshop and you would have to read up on web design basics, HTML, CSS and al lthat on a more general level or review your hosting provider's guides on how to set all this up.

How do I embed multiple font outlines in dynamic text field

Can anyone tell me how I can embed multiple font outlines in
Flash MX so I can get smooth text in a dynamic
text frame? I want to use Regular, bold and italic in various
parts of the text.
I was using the Character button in the properties manager
and tried to include all Characters. That does not work.
In the Properties manager I can choose Bold and/or Italic.
But it becomes a universal setting that overrides my HTML tags in
my external txt file that I am importing. I dont want all my text
to be bold.
If I dont select them in the properties, however, Flash will
not embed the font that it needs.
Is there a different way to embed fonts other than under the
Character Tab?
I tried to import fonts to the library, but can not select
them.
Your help would really be appreciated.
Sincerely,
ggaarde

Weird, it works for me on first go, always had in fact :)
Show you an example, try to compare to your file see if you

Hi! can any1 pls let me know how to create a look up table in labview and use that in the vi.

hello !
i have no idea how to build a lookup table(as v use in microcontroller) in labview and use that in vi.pls help me
txs
nitin
Solved!
Go to Solution.

If the lookup table is always going to remain the same (e.g. a character generator or something similar) you can place the values in a 2D array constant on your diagram, with the input value as one column, the equivalent as the other. When you need to perform the lookup you use an index array to return all the values in the "input column", search it using "search 1D array" and use the resulting index number to index the other column's data. If the values may change, then it would probably be best to load an array control with your equivalent values from a file.
