Hi, From "Current" invoke node, wire to "Get Text" property node, Select "Mod" Format, it would feedback Vendor specifici of Byte[], is it your goal?

Funny, works for me each time.

Did you actually remove and re-attach the device after uninstalling?

What OS are you using?

Shane.

Hi,Shane

Yes, I did .

My OS is "XP SP3"

Hi,

you referred to my USB nugget on the NI site....

There's an easier way to restore the "normal" functionality of your device without going into Regedit.

Go to the hardware manager and find your device. Right click on it and choose "uninstall".

That should do it. Remove and re-attach the device and it should work as "normal" again.

Shane.

HI，shoneill,

Thanks, but, assuredly I tried, like what you said, it is fail, then I would come to here to search the help. that kind of handle is very natural for every computer user I think. but it is still not help, the USB port becomes "USB composite Device" after I intall USB VISA RAW, uninstall it, and computer re-search the hardware, and restore what it was again and again.....

Problem solved, below thread for the solution:

Typing "Regedt32" at <Run>

Go to :HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\USB, find out the key whose name is corresponding of the VID/PID, firstly. change its right, and delete whole register key, lastly. plug in the USB device......

I followed below two links to try...

I use my USB Storage Device which is Maxtor OneTouch III (80G) movable disk for this experience, and It works, MAX can detect the device as I plug in, but the bad thing is coming out, I can't use this device as a storage device anymore, how to restore it ? can it be deleted from MAX(I don't want it to be recognized by MAX after experience), someone to tell me to reinstall the driver, maybe this product is so old, so I can't find this kind of driver everywhere, except this, should it have second handle?

Thanks Karissap this is what i was looking for ...But the problem is i cannot adopt this technique in my application because i already have a event structure i tried all possible ways of putting this technique into my code but its not working...I have a picture what my application looks like though this is not my real application but it is similar to this i.e. i have a event structure in one event i open tcp connection in second event i read and write and in third event i close tcp connection.In second event i display data in table were i need to do this.

I would like to make the table as a control, why not ? it can be written data also.

It is a separate license but there is no article number on the NI site for it and no scripting license you can buy. It is only for internal use within NI and maybe very selected strategic external contacts. The license Manager is here used to protect that feature from being easily used by us mere mortals.

Rolf Kalbermatter

Oh Yeah, thanks Rolf, and How do you know this ? my mean is, where did you get this information? from somewhere, some website? I am interested in this. thanks.

As hinted, in LV 8.x NI put scripting behind the license engine, so you need a license to activate it, which you can't get at the moment.

If you search this board, you should be able to find the PMS assistant or the Dataact property browser, which I believe should give you access to these properties and methods in 8.x.

Sounds like this should be added to the readme.

Hey Yen,

Oh yeah, which License LV8.x should activate? since my LV8.x is professional Development eddition one. I don't like to intall two version of LV (7.1 and 8.x). thanks to tell.

Hello all,

I am using IMAQ 2D barcode function, which is PDF417, but it reads the barcode display is an error characters, maybe it is the local language casuse (Chinese), PDF417 read barcode can't display correct characters, I have searched some of corresponding webside, and somebody tells, PDF417 vi output is binary code, and I tried to use type cast or string to byte array etc to do some convert, but no any result. did anybody meet this kind of case ? please help to share your solution, thanks.

QUOTE (Yair @ Mar 6 2009, 12:07 PM)

Scripting has been put behind the license engine in 8.x and NI does not sell licenses. The floated threads in this forum probably refer to this.

Well, Thanks, but I really like and want to know how I can get this function, just tell me how Michael has this ? anybody gives any thread that I will appreciate.

this tool is nice, but why I can't find the property node's item selection at the property putdown menu,e.g. "diagram" and that property which is not red one (because red property node tells that is an old version). even I have actived the ini file with SuperPrivateScriptingFeatureVisible=True

my LV's Version is 8.6, any setting I should append ? or LV8.6 remove that function ?

see attached png file.

I am also very interesting in this topic, I help to tab it on top for someone to see this for help, if this done, the LV interface would be much more beautiful !

Yup, two solutions

1. use 32-bit png image

2.use create mask.vi, see attachment.

Hi Justin: I am using version 8.6 as well. I have attached the code that I am using. The VI shows that my images are read-in as 8-bit ones. I know the newer 8.6 VI for reading images has a transparency threshold but does not seem to make a difference in my case. Are your images 8-bit or ?

..............

Hi, I think this is the focal cause, PNG file is 32-bit, alpha channal, R, G, and B.

Rolf Kalbermatter

WOW, Rolfk,Thank you very much, your help quite similar save my life, , it works. :thumbup:

but, as I open the example vi, it seems missing a BMP lib.

Enclosed is a source code package which from my friend helps to Call API to handle this case, but he just uses VB language, ant it works, so sad, I am not very familar with VB language, some part, I still fail to call API, should anybody help to "CONVERT" it to LabVIEW ? many thanks.

QUOTE (Dirk J. @ Jan 1 2009, 04:31 PM)

I think you can also use the PictureBox .Net control. It blends automatically with the background.

OH yeah, Upstairs's handle is so easy! nice.

Wow, I made it, Thanks PJM again (ResultingColor = SourceColor × alpha / 255 + BackgroundColor × (255 - alpha) / 255, it works :thumbup: ) and all you guys. :laugh:

thanks all,specially thanks PJM, the function is so cool(from the video, that is what I need ), but the "Create mask.vi" can't not make translucent effect. just transparent. I have no idea to deal with it.

Thanks All your guys, all of you are very kind, I appreciate !

maybe, I hadn't gave the clear question, all your help is focus the transparent effect, actually, I want to display the PNG image with its original face. where is translucent where it should be, it is not making whole image is transparent.

QUOTE (PJM_labview @ Dec 18 2008, 06:25 PM)

Ton, is correct.

I have code that I wrote a while ago that do just that and it works like a charm.

PJM

Hi PJM,

Then, would you share that simple code for study ? thanks ?!~

Also when you put image on front panel as a decoration transparency smoothness is preserved. I was playing around with scripting trying to dynamically change such decoration, but without success.

and, I find LabVIEW platform an internal function which is "import picture to clipboard", it is powerful function, it can import many format image, e.g. Jpeg, Bmp, PNG and GIF, animation too, Wow, how NI does this, if we can call this function(even Scripting), it is nice, because We can get image from clipboard. but I fail, though I enabled LabVIEW scripting too.

and I found, if import an animated GIF picture to clipboard, add loop for get image from clipboard and run this code,you would find, the image displaying on picture control is animated too!

Oh Yup, if we can regard the front panel as a huge picture control, and dynamically load PNG or GIF image, it is nice too. :thumbup:

QUOTE (Ton @ Dec 17 2008, 08:04 AM)

Or you could build your own, the image data returned from a read png file contains the alpha blending info, if you really want to you could write your own alpha-blending routine.

You would need to get the image behind the picture control and do your calculation but that should be doable.

Ton

All right, Ton, I enclosed simple code, there are my query on front panel, I don't think it can be done. Please give your thread, thanks @!

as my subject, I wish LV can handle or display translucent PNG or GIF image on picture control, sometimes, my PNG image's edge is having translucent looking but LV can not display its realistic face, the edge part lose something, and I have to use Web ActiveX to display it, but this kind of ActiveX is differently handle image data......
