I have a DLL I created (in Labview) that takes in string information, does some magic crunching on it to create a password that is passed out as a string. This DLL will be called from CVI and probably from a C# application.
This should be so simple, however I cannot figure out how to pass the string in and get the modified string out of my DLL.
I've had no luck at all getting this DLL to work by trying many different things. It crashes LV, returns and error, or simply passes nothing out during my trials.
I've included the project (its small) in zipped format. Can one of you kind souls take a look at my code and tell me what I'm doing wrong, or what I need to do correctly to both, configure the DLL and then call it from LabVIEW?

For years now in the student labs we've used firewire video cams and the IMAQ 1394 driver to create AVI files which then get read and converted to intensity arrays for motion analysis in a Labview app. The cheap cams are going extinct, and they want to use I-pads to create the videos which are MOV Quicktime format. So far it looks like the I-pad app they want to use can't be made to spit out an uncompressed AVI. So now I need to find out if I can either:
1) automate conversion of an MOV to uncompressed AVI and continue to use our LV analysis app as-is, or
2) find a way to parse a compressed MOV video to a frame-by-frame intensity array, and build that into our LV analysis app.
I am starting to search, but is anybody aware of an existing library or methods so I don't reinvent the wheel?
Name: RCF LVS Conversion Toolkit
Submitted: 20 Mar 2015
LabVIEW Version: 2009License Type: BSD (Most common)
We have recently developed a toolkit that allows you to use Quick Drop plugins in Right Click Framework or LabVIEW Speak platforms.
Named RCF LVS Conversion Toolkit, this toolkit provides an easy solution for JKI Right Click Framework (RCF) and LabVIEW Speak (LVS) lovers who want to use a quick drop plugin in RCF or LVS. Now, you wont be disappointed when you see a useful plugin not written in your favorite platform's plugin format.
Procedures are simple:
Open the toolkit by going to Tools Menu >> Synovus >> RCF LVS Conversion Toolkit... Select the target Quick Drop plugin VI Type the command name in Right Click Framework or LabVIEW Speak Click OK
Now you can use the Quick Drop plugin in Right Click Framework or LabVIEW Speak platform
Automatically converts a QD plugin to RCF or LVS plugin format Warns the user if repetitive commands are installed. Provides an instruction as user clicks help button. Helps the user navigate to the plugin folders (LVS, QD and RCF) Modifying the functionality in Quick Drop VI will automatically update the functionality in Right Click Framework or LabVIEW Speak
Please let me know if you have any questions. Suggestions and comments are welcome
Note: RCF and LVS only update their lists of commands at startup. If you use the RCF LVS Conversion Toolkit when RCF and LVS are open, please restart these platforms.
