Does anyone know how to activate scripting on a Mac (LV 8.5.1) ??

Cheers

If I only want to read from the 7th element in the binary file, should I read the whole file using the read binary file VI and then use array subset to take out the useful part?

Hello,

You can do that but this is not the only way. Between LabVIEW 7.1 and 8.5 the File functions have changed a bit - and in my opinion its easier to use now but there is a lack of documentation. See below.

Just here to add my 2 cents, this won't work for all situations (like other operating systems) but could you use a windows DLL to act like you are pressing keys on the keyboard? Like in your LabVIEW program ask for the user name and password, then call Skype, wait for the login dialog to be active, and send the user name and password as keyboard keys (with tab in between) then return.

This doesn't use any kind of API, and is very prone to problems (like if Skype happens to change the login dialog) but for a quick and dirty solution I think this should work.

Hmmm... well... I'm not sure there is a method to launch the login dialogue in the skype4com API, which would just close the debate.

That said I know I've once use a windows dll to set the cursor position, I image it's also possible to "fake" a clic and some keystroke - so technically you're probably right - but all that is kind of ugly and really unsafe .

Not sure I'd pass the LAVAcr requirements if I do that

this brand often has good adds !

I'm not sure that LMGTFY is a good idea - the first two search results point directly back to this thread

Yes... now... but this thread might not have been in the search results if the search was done before, that's the whole point :laugh:

When I use LMGTFY, I always check that the results are interesting enough. That said, it's true it would have taken me less time to point Joaquin to the thread called "http://forums.lavag.org/Scrolling-a-tree-control-t12725.html' target="_blank">Scrolling a tree control" I just wanted to show how to look for it.

Hi

I'm trying to control the vertical scrollbar position of a TreeControl in LabVIEW 8.5.1

String controls have Text.ScrollPos property, to control it, but in a TreeControl I don't find a property to do the same.

The reason because I need to control this property is due to I'm writing data quikly to a TreeControl. If I write data cell by cell is very slow. Then, I'm writing the full content each time. I delete it all, and I rewrite all the new data in the tree control.

Then, I have to store the VerticalScrollPosition, and after write data, I have to put it in the same position.

I'm doing the same with visible properties (expandable) of each cell and it works... but I'm no able to find the way to control the scroll bar.

Any idea?

ThankS!

I do have an idea, but first http://letmegooglethatforyou.com/?q=labview%20tree%20control%20scroll' rel='nofollow' target="_blank">LMGTFY .

The Skype SDK has just passed through LAVAcr process :laugh:

There we go and here for bug report and feature suggestion

Happy Xmas all

... and please have a quick thought for those of us who are working today (wednesday) and friday

Disable structures work great for this.

With LV 8.0 I remember having some troubles with the disable diagram structure.

Code was executing quite slower and I had some issues when building applications, maybe these issues have been fixed since then though.. Have you ever had these problems ?

QUOTE (Phillip Brooks @ Dec 19 2008, 03:00 PM)

I'm upgrading a bunch of 7.0 code to 8.6. When I load a 7.0 VI that uses a case structure with a constant on the block diagram to disable code, LabVIEW converts the constant to a hidden control and reports a warning while opening.

I think a constant causes the contents of the unused case to be optimized "out". If you're creating a new VI in 8.6 and have used a constant, maybe converting it to a hidden control will help...

I noticed that as well and was not really creative, I make boolean controls and hide them ; I also enabled the "show constant folding" options to get this :

Thanks all for the kind words

It's an honour to step in and help a bit

Hope I can make it to next LAVA/OpenG BBQ to get real :beer: with you all

This has been discussed here.

But maybe you should try to search like this

Hope this helps

Dear

I have generate a freguency from 100MhZ to 3GHz with a step of 50MHZ. I want to save the every frequency in like first it is 100MHz then 150MHz and next 200MHz and is so on. How can I do this operation in labview. Here i have atached the labview fle for better understanding

the eayiest way is probably to use the "write to spreadsheet file" function (to be found in the File IO palette), and link the array of frequency coming out of your for loop to the "1D data" input.

There is probably no way to disable this completely. At least the first time you really do want to have this security check as otherwise every virus could connect to Skype and (ab)use it for whatever it wants. MS had this in the past that any application could conenct to Outlook over ActiveX and that was a perfect way for a Virus to harvest the entire email address list as well as using the Outlook credentials to send out tons of spam mails. So they had to disable unnoticed connection to Outlook over ActiveX with a security patch.

Maybe that Skype will cache a once given acknowledgement for a specific application somehow so it won't prompt each time again but the first prompt you do not want to give up ever!

Rolf Kalbermatter

That makes a lot of sense indeed. And (more than) probably for the same reason there is no method to pass in username and password.

I'll have to document that in the API

QUOTE (rolfk @ Dec 18 2008, 10:04 AM)

it seems if you open a reference to the SkypeClient interface you can define the user to login with in the IClient.OpenAuthorizationDialog method but it has no password so if this is what you are looking for it will simply put up a login dialog to prompt the current user for his password.

I tried this method but in fact it does open the login dialogue, it opens the dialogue that lets you ask another skype user to be added to your contact list.

QUOTE (rolfk @ Dec 18 2008, 10:04 AM)

I'm not really sure but it seems to me that this is to allow an application to connect to Skype using ActiveX.

This is a point I really want to dig in before I post my code to LAVAcr because currently when using my skype API in LV, skype prompts the user to allow LabVIEW.exe (or mylabiewapp.exe) to connect to skype.

QUOTE (LV_FPGA_SE @ Dec 18 2008, 05:01 AM)

Have you looked at the Skype4COM documentation?

https://developer.skype.com/Docs/Skype4COMLib

It has a complete list of the classes and methods/interfaces.

Yes, that's exactly where I started from. I didn't find a way pass in the username and password to login with the account I want

Dunno if I missed it or if it's not possible with Skype4COM..

QUOTE

I don't feel comfortable enough with the registry to go dig that way. thanks for the idea anyway

As I said here, I'll soon post the small skype API I've come up with to LAVAcr, then anyone will be very welcome to help improve it.

[...] or can u tell me where i can get starting examples of labvie visa uses???

Go to Help >> Find examples >> Search tab and search for "visa" there are some examples that ship with LabVIEW.

If you start with LabVIEW, I think the example finder has to be the first place you look for

Hope this helps

I think that "DAQmx Write" automatically starts the task if it's not explicitly done yet, the error you get in the second screen-shot comes from the "DAQmx start.vi" and it says that it can't run a task that is already running...

I suppose that if you just remove the "DAQmx start.vi" it should work.

Hope this helps

Hi Antoine,

You don't require scripting for these properties.

I was talking about methods for Pages[].

The only methods for I have for a Page are these :

Does anybody know how to add new controls to a tab pane? I am working on a test-executive, and I'd like to have LabVIEW choose which graph to display, depending on what kind of data the user is taking. Ie, either chart or 2-D color graph, etc.

Also anybody know how to add/delete tab panes dynamically? There don't seem to be these options w/ the properties/methods of the tab. thanks.

I don't think you can dynamically add/remove pages on a tab control.

However, you can create as much pages as you'll need a edit time and then at run time choose which of these are visible ; that would also do the trick for the data type : instead of creating the desired type of graph dynamically (which I think is not possible) just select and display the appropriate tab.

Hope this helps.

I have scripting enabled but I never saw these methods for Pages[]

Could you post a screen-shot of that ?

QUOTE (crelf @ Dec 12 2008, 09:04 PM)

I don't think so - it looks like you're covering most of the use cases.

Ok, I'll do some cleaning and go through the LAVAcr process

Hi,

There are some mistakes in your MathScript node :

- you define a for loop with i going from 0 to "N-1" but N isn't defined

- the cvariable "k", used inside the for loop is undefined as well.

If you correct these mistakes it should be ok.

Hope this helps

QUOTE (crelf @ Dec 12 2008, 03:50 PM)

How comprehensive and mature is the API that you've created? It might be a good candidate for the LAVA Code Respository.

I thought about that but I wanted to have more functions before releasing a candidate, at the moment it's just a small handy API I use during the long test process of my applications (I mean over week-end).

The functions I have at the moment are these :

- Launch / shut down skype

- Check if connected

- Get / Set Mood (when logged on)

- Get contact list (when logged on)

- Send chat message to a contact (when logged on)

- Send sms message to a contact (when logged on)

One thing I didn't find yet is how to connect with a specific username and password, see here.

As you can see it's pretty limited. At the moment I use it as an easy way to see from home how my week-end test are performing ; for this I created a skype account for the application and from LabVIEW I update the mood to see what's going on.

Hey dudes,

I need ur help in sending a SMS in labview. pls help me out.

Thanks

I'm using my skype account to do this.

I use Skype ActiveX in LabVIEW to send SMS, it works fine as long as skype is running on the computer and logged onto an account with some credit.

Are you interested in that solution ?
