How to open a 16-bit dll in Labview

Hi,
I would like to open a vi for a spectrometer (Jobin Yvon 270M), but I get the following error message: "A CIN tried to load a 16-bit dll. This operation is not supported under Labview for Windows 95 or Windows NT. The CIN and DLL must be recompiled". Is there any way how I can open the 16-bit dll in Labview? I´ve read that it could be possible by writing a Thunk DLL(???). Do you have some advise how to solve this problem?
Thanks a lot,
Markus.

This isn't a LabVIEW issue, but a Windows issue. To call 16-bit code from a 32-bit OS you need a bridge. That's what the thunk is. You can read more from this MS KB article. There's also this NI article. Not for the faint of heart.

Calling 64-bit dll from labview 8.2 on Windows7

Hello,
I have tried the LABview driver from the OMNIDRIVER (OceanOptics) package. But when calling functions from the “OmniDriver32.dll” , LABView is crashing and says that the memory is corrupted.
I am using LABVIEW 8.2 (32-bit) running on Windows 7 (64-bit). I have tried some LABView code examples given for LABview 7.1 and 8.0. These example are using the OmniDriver32.dll (not the OmniDriver64.dll).
But maybe these example are assuming that you are on a 32-bit operating system, which is not my case.
So I have tried calling the OmniDriver64.dll. but LABView seems not to recognised the dll and can’t read the included functions.
Is there a way to call some 64-bit dll from LABview 8.2 ?
Or do I need to buy a new license for LABVIEW 64-bit ?
Thanks,
Pierre

There is no virtualization support for DLL bitness issues outside of the Windows standard directories. The Windows and System directories that an application "sees" depends on its bitness. All other directories are not mapped depending on the calling process' bitness.
So if you have installed 32 Bit LabVIEW and are not calling one of the system DLLs, you have to point the path of the DLL to the real 32 bit DLL. Pointing it to a 64 bit DLL should not even be able to get the VI compilable, since Windows will refuse to load the DLL into the 32 bit process as being an unknown file format, and that should make the VI broken.
If you need to call a system DLL you simply enter the DLL name without path and Windows will find the according DLL for LabVIEW.

How to make a driver using DLL in LabVIEW?

I had followed the "Using Exteranal Code in LabVIEW" manual having finished the making dll file, and the lsb file(I attempted that two ways). But when I load the code in LabVIEW, it can't work. I don't know what had happened, I only got a error message like this:"'0x100014f1'commond call memory'0x00000000',this memory can't be written" or other similar error message, if I push the "enter" button, the vi application which I having lunched will crash. If I push the "cancel" button, the debug model will start,and the next message is "Unhandle exception in LabVIEW.exe(MSVCRTD.DLL/LVS95.TMP/COUNTER.DLL(the last one is creat by myself)):0xC0000005:Access Violation", but I wonder what had cause this? My DLL had been made successf
ully under the VC++6.0, why LabVIEW can't call it fluently? How to make a driver for my own device using LabVIEW? How to correct my error to finished my hole work? Thank you very much. Jacky Wei

1. Can you call this DLL from within VC?
2. What operation system do you use? There may be a problem with calling of win95 dll under NT or win2000 for example.
3. If you use NT you may not have permissions to work with some ports and memory areas.
4. Under NT or win200 try to compile the library as a 32-bit dll, and under win95 - as 16-bit one.
Good luck.

How to open sounds and audio properties using Labview function

Hi All,
How to open the sounds and audio properties of the control panel using the Labview system exe vi.
Is there any dll also to open this property.
If there is dll which is that and how to program the dll to serve my purpose.
Solved!
Go to Solution.

Have you looked at the "Graphics and Sounds" section within the Functions Palette (Block Diagram)? There are VI's that already exist for this.

How to access a 64 bit DLL from MATRIXx UCB

I have a third party LIB and DLL (I don't have source code) that I need to integrate into a MATRIXx simulation. They are compiled as 64 bit binaries, which won't link into a 32bit MatrixX solution. I am opening MATRIXx from the VisualStudio x64 Win64 command prompt to define the correct environment variables.
The actual error is from the Visual Studio 2010 linker:

I have tracked most of these references to libUcbUtil.lib. All of the copies of this file in MATRIXx 7.2.6 are 32bit. Is there a 64 bit version of libUcbUtil? More importantly, am I on the right path to resolution or will I ultimately be asking for a complete 64 bit delivery of MATRIXx?
Thanks,
Kevin

Are you certain that is what is actually happening via. Wireshark or some other packet sniffer? Yes, I verified with wireshark that the jar is indeed being redownloaded each time getResource is called.
The reason I ask is that the plug-in was changed in recent times to not report the true path of a jar on the file system. Perhaps that is what you are seeing in the logs. The URL that is created by getResource looks like this:
jar:http://localhost:8080/jar/applet.jar!/com/homepage/images/icon1.pngThis URL obviously references the remote jar rather than the local jar. So I guess the real question is how do I reference the local jar?

How to use a C# dll in Labview?

How can I use a C# dll in Labview 8.2? With the "Import Shared Library" Wizzard I need the header file which I don't have. Is there another way
to use such .dll to import the functions created in C#?
Thanks in advance
Norick

Norick,
afaik there is no tool which provides you the possibility to create something like an instrument driver for .NET assemblies.
Maybe we should take a look into terminology:
- Instrument driver: This is a set of functionality, which provides the user with an easy to use API for a special instrument. Very often, the driver itself is written in C/C++ and provided as a DLL.
- "Import Shared Library" Wizard: This wizard enables the user to create an own API for any C/C++ DLL (or compatible) for LabVIEW. This wizard requires the information on all exported functions; this info is contained in the header file. The result of the wizard is a set of VIs containing one Call Library Function Node each for each exported function.
- .NET assembly (extension .exe OR .dll): This can be compared to ActiveX. So the way to program with .NET is similar to ActiveX. Maybe you want to take a look into the examples of LabVIEW regarding .NET...
- Global Assembly Cache (GAC): All assemblies contained here are registered in the system. Every application can easily work with assemblies contained here.
- Private assemblies: This would be the way to work with .NET assemblies which are built on your own. You have to select the .DLL-file itself and make sure that the file can always be found in the same (relative)folder of your application.
hope this helps,

How do I get iTunes to open in 32-bit mode if I don't have a Mac, just a PC

I am trying to play a tv show on my PC that I bought on iTunes and it says I don't have the Quicktime, or something like that. So I downloaded a new Quicktime and it still says that. So I clicked on more info and it took me to an Apple page showing how to get iTunes to open in 32-bit mode from a Mac. I have a PC and I need to know how to get iTunes to run in 32-bit mode

You can use "History > Restore Previous Session" to get those page back.
Are you restarting this way?
# Close Firefox
# Open the Applications folder in Finder
# Right click or control-click the Firefox.app icon
# Select "Get Info"
# Select "Open in 32-bit mode"
# Close the "Firefox Info" window

Bridge CS4 only opens PS CS4 64bit -- How to change to 32 bit?

Opening a RAW file in Bridge CS4 automatically opens Photoshop CS4-64bit (via Camera RAW). Is there any way to have it automatically open the 32-bit version instead?

I'd like the option to choose EITHER the 32-bit OR the 64-bit version for RAW or for JPGs. It is not obvious how to do this.

How to open RAW files in 16 bit mode?

In Photoshop CS3 all my RAW files opened in 16 bit mode. In CS5 they all open in 8-bit mode. I've looked all over for where this setting might be made but I can't find it. How do I tell Photoshop or Camera Raw to open images in 16 bit mode?

That does it. Thanks!
I may have missed it in the Help files, but I sure couldn't find it. Help tells me all about why I want to use 16 bits, but not how to get them.

How to open the file types of iOSAPP(ipa),EPUBfile(.epub) in windows 7(32 bit)

iOS apps can be added to an iTunes library and thereafter transferred to an iOS device. They cannot be opened directly on a PC.
epub files can be added to an iTunes library, and thereafter transferred to an iOS device where they can be read with the iBooks application. Files protected with Apple's DRM cannot be opened directly on a PC, though there are programs such as Kindle and Calibre that will open non-protected epub files.

How to open .dll files?

I'm not sure I have the correct forum, but I thought I'd try here.
I have .dll files I want to look at. I am unable to open them in any type of readable format. When I double click on them they open in Text Edit and jumbled up. I tried to open them in Preview and that didn't work either.
Can someone guide me on how to open these files? OR if this is the wrong board, let me know and I'll post some place else.
Thanks,
Ginger

No. A Windows DLL file is a library of machine code meant to be loaded by a piece of software. It's unreadable by humans. An experienced developer may be able to decompile the library into x86 assembly language.
DICOM is an image format used for storing medical image data (such as MRIs, CAT scans, etc.). Many packages that work with DICOM packages have an "export to CD" function that will burn a CD with a directory of DICOM images, optionally with a copy of a program for displaying the images. It sounds like you have one of those CDs that's been burned with a copy of a Windows DICOM viewer. You won't be able to use that without a copy of Windows installed.
However, that doesn't mean that you can't view the DICOM images. The most widely used DICOM viewer is probably [OsiriX|http://www.osirix-viewer.com>, which is free to download and use. Simple install, and use the import function to load a whole directory of DICOM images at once.

How to open 32 bit PNG with unpremultiplied alpha?

I've got the latest Photoshop CC (2014) and I've been trying to figure out how to import a 32 bit PNG file with an embedded but unpremultiplied alpha channel in it. So this is a PNG image with four channels: Red, Green, Blue, and Alpha. Unfortunately, when I open it in PS, I get a three channel (R, G, B) image where PS has cheerfully premultiplied the alpha into the other channels, as you can see here:
The "glow" is the Alpha channel's unwanted effect.
I know the Alpha channel is still there because if choose Channel-->Split, I get four grayscale images: myimage_red, myimage_green, myimage_blue, and myimage_transparency.    So the Alpha information is being kept separate, but PS is being "helpful" and premultiplying it on the open.
Is there a setting or anything else that can overcome this behavior?
Note: The reason for this is that I'm using the "alpha" channel for something else (ambient occlusion) in a CG program and it should not be being used for transparency at this point.   (Long story.)

Thank you for your prompt response!   I apologize if I misused the term "premultiplied."   Here's what I am familiar with the term from:   https://helpx.adobe.com/premiere-pro/using/compositing-alpha-channels-adjusting-clip.html
With straight (or unmatted) channels, transparency information is stored only in the alpha channel, not in any of the visible color channels. With straight channels, the effects of transparency aren’t visible until the image is displayed in an application that supports straight channels.
With premultiplied (or matted) channels, transparency information is stored in the alpha channel and also in the visible RGB channels, which are multiplied with a background color. The colors of semitransparent areas, such as feathered edges, are shifted toward the background color in proportion to their degree of transparency.
So, here is what I see on my Photoshop screen when I open this image. Note that there are only THREE channels displayed, Red, Green and Blue (and the composite RGB channel). All three of them display transparency, allowing the (in this case checkered) background to show through:
Now, if I select Channels-->Split Channels I get these FOUR images.   Note that there is a "Transparency" channel which has my separate information that I want, and there are three color channels, none of which display transparency.   This is what I meant by "premultiplied".   In the default mode above, Photoshop has "multiplied" each color channel by the "Transparency" channel.   This is the behavior I was seeking to avoid.    Can you offer any further advice on how to prevent this automatic use of the "Transparency" layers, or is this something that Photoshop does not support at this time?

"Blue"
"Green"
"Red"

How to open 32 bit software on a MBPR

I Have a slide scanner but because it's a few years old, it's a 32 bit software device. How can I have my MacBook Pro retina 13" open the software? The instructions from the manufacturer say to right click on the app (SilverFast) and select Get Info, then click on the check box to make it open in 32 bit but there is no check box to allow that to work.

OK... good news! I found a new driver for the scanner, circa 2011, and installed that plus I got a response from the software developer
('I assume that you accidentally used the "Get Info" of the SilverFast
installation folder instead of the SilverFast 8.app itself. Please try
to right click the SilverFast 8 Dock Icon -> Options -> Show in Finder
As a result of this action, a new Finder window will open and the
SilverFast 8.app will already be highlighted in this folder. Please
try to set SilverFast 8 to 32bit mode using this way again.')
After installing and following the above comments, I then found a check box for 'run in 32 bit' to allow me to run the app and scanner. I haven't had time to test this yet but I should be able to test it later this week... very busy training all this week.

A site I use every day told me today that it would only open in 32-bit mode. I cannot change this in system preferencees as suggested. Could anyone explain to me why suddenly, and how to change this? (MacBook Pro 10.6.8) Thanks!

Hi. I am in need of advice - and am not very IT savvy! I have a MacBook Pro 10.6.8 OS. A site I use every day told me today it would only open in 32-bit mode. I researched and found some advice on how to choose 32-bit mode in system preferences. I do not have that box to click in system preferences. Can anyone tell me as to why suddenly this has happened, and any suggestions on how to go back to 32-bit mode would be great! I did try restarting holding down the 3 & 2 keys as suggested too. No luck. Thanks for any help.

Does the site use 32-bit mode Java? If that's the case, you should have both 32 and 64-bit enabled though Java Preferences in your Utilities folder:
See what you have enabled...
