Ok, I managed to get the code above to work properly. There was a missing x86 VC2010 runtime dll on the target computer. the x64 was installed as a default, so I had to explicitly install the x86 too.

I compiled both 32 and 64 bits, the 64 bit works without a problem. I think I will rename the DLL themselves, as Shaun suggested. This solution smells like a hack, what happens after a software update? The programmer needs to remember to rename these files? I tried to be smart. 

There is also an .INI file which directs to the API install path. It has just one line. C:\program files (x86)\signal hound\spike\api. I verified that the generated path is ok. Rolfk, this might explain why the same code works with the invoke nodes having the DLL path predefined. It should have behaved the same in both cases, or, at least report a file not found error (#7). I even tried placing the DLL in the same directory as the executable, which is one of the location windows searches for them, and got the same error.

Hello,

 I wrote an application which can use either a 32 bit or a 64 bit dll, it loads the dll from a path specified in an INI file. This code works properly on the development machine (LV2013, both 32 and 64 bit, both with a debugger and as an EXE) but doesn't work on the tester machine as an executable. It throws error code 13 (in LV2013 - file is not a resource, in LV2014 - Failed to load DLL due to invalid format or missing dependencies). 

However, when I change all the Invoke nodes to use a static predefined path, everything is OK.

What am I doing wrong here? I rather maintain one code base and build for each target than maintain a code for each target.

The API dll is from signalhound.com http://signalhound.com/spike

Autodesk Trueview or DesignReview has a COM (ActiveX) component that allows LV to display a DWG file. 

Check the Excel .NET API reference from Microsoft. The application object has an option to start hidden.

Do you use the MP3 files or the original .MOD files?

Those buggers cannot be all facing the same direction, that ship was way too slippery to control.

I hope you know about this:

Civilian GPS have velocity limits encoded into the firmware (~500m/s). If your rocket surpass that, you can't use GPS.

It depends on what sort of peripherals and how many events/hour you require. A unit which reports once a day can last years on a single LiSOCl AA battery, on the other side, a smartphone which has its transceiver and CPU always on lasts a day or so.

They are expansive, however, I can ask regarding some of our older, unsupported products, since your requirements are relatively simple.  

RTLS systems can be quite expansive, especially with these requirements. I work for a company which makes such systems, indoor/outdoor location, sensors and relay outputs, LCD on the agents, GUI and even a LV API. We have used the system in the past to track workers in a construction site.

Another company is Aeroscout, which can use the wifi infrastructure for their active tags access points. Their main market is health care (tracking equipment in a hospital).

Wireless takes too much energy compared to wired. Personally, I prefer optics.

That is very interesting, I wonder if these properties can be exposed somehow.

You use the system exec.vi under the connectivity palette to run the AVRDUDE. 

Version 1 was uploaded. It has all the features I wanted, that is, a bi-directional interface between a standard browser and a LabView application. There are still scale-ability issues, which will require a more capable messaging library (0MQ is my prime candidate).

You need few packages, OpenG and JSON Labview, both available from the code repository here, or better yet, via the VIPM.

Check out the LabView <-> google maps code on the code repository. It translates LV variants to Google maps JSON objects, and sends them via web socket to a browser. You can easily draw a polygon wherever you want with those VIs.  

Edit: Here is the link: http://lavag.org/files/file/236-labview-google-maps-websocket-interface/

File exit keyboard shortcut is Alt + F, and X usually. Without a menu option, it is Alt +F4 (Windows and some linux distros) which is a bit harder to press with the left hand. This can be either good or bad, depending on the application.

Also, if the device's MAC address is known, you can use arp or netsh to map an ip address to that machine.This requires administrator privileges in windows.

What sort of device is it? Some vendors have their own auto config protocols.

If you use windows, there are examples in the Labview help on how to use the Excel ActiveX control, You can use different worksheets without much effort.

These examples also show how to fill a range of cells with a variant, which provide an elegant solution to your problem.

Hello,

 I have stopped supporting this code, please use the web socket one, for better functionality. 

I have only tested the .NET VIs under windows XP 32 bit with LV2011, and didnt manage to recreate this error.
