Hello, I want to install only really needed parts on target PC (WinXP).

My application uses NI-CAN.

I should to install LV-Runtime + NI-CAN, but if I select NI-CAN in installer, I can't unselect MAX, C++-Language Support and so on. I can only install full NI-CAN and all the additional shit will be installed on target PC.

Where I can unselect additionals?

Thanks, Eugen

You can try to implement the WDM/DirectX/Direct Show in LV or bye the Vision Module by Hytekautmation http://www.hytekautomation.com/Products/IVision.html

Yes, right klick, then Advanced->Customize, then Save as Typedef.

Please take a look at the attached pic and tell me where I can locate this labview tool.

First Call? Indicates that a subVI or section of a block diagram is running for the first time. The First Call? function returns TRUE only the first time you call it after you click the Run button. You can place the First Call? function in multiple locations within a VI. The function returns TRUE the first time the section of the block diagram in which it is placed runs.

Eugen

P.S. look LV-Help

Probably it's possible to use DirectShow by .NET assemlies. Any experiance?

Eugen

Have anybody work with WDM ? It's possible to create a driver for capturing video devices and use this in LV?

My collegue created an ActiveX (ocx) with Borland C++ and I use it succesfully in LV, but I want to create my own driver without using ActiveX.

Any infos?

Thanks, Eugen

ActiveX is Windows specific and (if I'm not mistaken) requires that you follow some very specific rules and it was probably decided that it's not worth it.

The RTE itself is exported as an ActiveX object (that's what you get in a remote front panel), so you can enable the web server in your executable and have people embed the RFP object in their UI.

If you want data communication, a DLL or TCP communication is proabably the way to go.

Yes, you are right, ActiveX is windows specific interface. Can you tell me how I can build in a LV element(e.g. controls) in other programms using DLL?

BTW, I never liked either option, but did you try using the navigation window (Window menu in 7.1, View menu in 8.x)? If I remember correctly it's faster than Bird's Eye View, but it's been a while since I used either of them.

I have never used navigation window because my VI are not larger as an monitor screen but I want all installed tools works. Probably I will use it in the future.

Eugen,

Can you check in VIPM if you have the latest package installed (1.7-2) ?

Thank you PJM for this answer. Dictionary pack is ok, but your Birds eye dont works.

1) if I start this tool I get this error message.

http://forums.lavag.org/index.php?act=attach&type=post&id=6091

2) I think the FP Bounds are not correct.

http://forums.lavag.org/index.php?act=attach&type=post&id=6092

3) Than I change FP Bounds to appropriate and it starts, but in the next SubVI called by Birds Eye Tool I get following error message.

http://forums.lavag.org/index.php?act=attach&type=post&id=6093

and the window shows invalid type.

http://forums.lavag.org/index.php?act=attach&type=post&id=6094

Did you check this tool on more LV versions before releasing ?

Eugen

Hallo,

sorry if it's the false forum for this question. I search for Documentations for all available OpenG Packages and Tools, like Dictionary, Python Tools, Bird Eye Tool or other packages and tools.

Hello, I wish to be able to create ActiveX (.ocx) elements with LV Application Bulder. I know I can create DLLs and EXEs, but ActiveX is not supported by Application Builder.

Eugen

In realy attached VI had to be the main.vi and not the splash. Fitstly without the Transparency-Part. But I saw that the empty window of this VI appears and stays on screen, then I got the idea to make a splash screen from this VI. It works now, no more problems.

Thank

Oops, sorry.

After testing repeately the window of splash screen hides realy and don't stay in the task bar. All right.

I can't understand why it works now, but it works.

Thank you for answers.

Hello,

can anybody say me why if I make the state of my splash window FP to "closed" (picture2), than my application stops completely. To hide the FP(picture1) does minimize the window, but I want to hide it completely.

Thank you, Eugen

P.S. my splash screen VI is the top level.

i want to use example for read from serial port ,

but i need known what is the condition for correct reading(from 8051 serial port comm)

You have to make the same configurations like baud rate, start and stop bits on BOTH sides for right communications over serial ports.

QUOTE(Randy81 @ Jun 4 2007, 09:56 PM)

Is it possible to run two separate front panels running at the same time such that one front panel can control the other? It's important that this isn't done as a subVI.

Yes, you can use VI server methods to do it.

Eugen

You can do it so or use OpenGs index array VI.

lt means "cheers" in polish (and maybe also in czech, I'm not sure).

It means "Gesundheit!" or "Here's to you!" and will be spoken like "cheers". It's russian.

Eugen

Ok, my solution is following.

More ideas?

I'm not entirely sure I understand what you are trying to do, but if you have 8.2.x or perhaps 8.x, then in the Utility folder of your vi.lib there will be a VariantDataType.llb which has subvis for interpreting variant data-types without getting your hands dirty looking at the flattened data.

I have to parse any data. The transmition-protocol is ready defined.

http://forums.lavag.org/index.php?act=attach&type=post&id=5970

So I made me typedefs for every package type. This one is the status package.

http://forums.lavag.org/index.php?act=attach&type=post&id=5971

My unflatten.vi should parse this package.

http://forums.lavag.org/index.php?act=attach&type=post&id=5972

Thank for your answer. I don't really know if I can use here Variant.llb. And I have LV 8.0.
