File not found when trying to call a dll on LabVIEW Real Time machine

I have a dll called "DLLRTTEST" that I've written, and have succesfully called on my host machine. I'm now attempting to call this dll from a vi that is located on my real time computer. Currently I get an "Error 7 occurred at Call Library Function Node in DLLRTTEST.vi." message upon execution
In the attached screenshot I'm trying to ensure that the vi I'm running is in fact located on the real time system. I then use a "Check if File or Folder Exists.vi" to confirm that the dll that I'm about to call does exist on the real time system as well. However, I still receive an "error 7 file not found" error from the Call Library Function Node.
Any help is appreciated.

As nathand already mentioned, depending on your C toolchain your DLL will depend on other DLLs. Usually the according msvcrtXX.dll that matches your Visual C version, if you use Visual C, other runtime DLLs if you use a different C environment. These runtime DLLs are even necessary if you do not call anything in any of your functions, since the DLL makes various initialization steps when it gets loaded and that references some C runtime functions nevertheless. Compiling and linking the DLL with static C runtime is usually also not a clean solution since the linked in C runtime will then reference Windows APIs that are not available on LabVIEW RT.
Depending on your version of LabVIEW RT you will have some mscvrtxx.dll files in your system directory but it will be an older one than from the latest Visual Studio version. If you can compile your DLL with that Visual Studio version then you should be fine, but could possibly run into new problems if you later upgrade to a newer LabVIEW RT version. Installing the C runtime distributables from newer Visual Studio versions is unfortunately also not a solution, since it references many (undocumented) Windows API functions that are not available in LabVIEW RT.

Error 404: SRVE0190E: File not found when trying to access jsp

I am using RAD (new to web dev) for some reason my app is unable to find .jsp's when they are not in the web content folder. I have a predefined package for my jsp's and when I run my servlet I get
Error 404: SRVE0190E: File not found: /WEB-INF/classes/app/view/search.jsp
now if I amend my URL in the servlet to "/search.jsp" and move the jsp to the web content folder, it works. I just don't understand why it cannot find the file when I put it in the package I created and link to it, but finds it just fine in the webcontent folder. Is there some unwritten rule JSP's MUST be in the webcontent folder? Because when i do that, then I have issues with my image links for the GUI (get red X's for all my images regardless of the fact they are linked properly.) Basically if I put my jsps where I want, look fine in design and preview, but the jsp isnt found when executed, if I move them to the web content folder the images no longer work but the jsps run. I am getting rather frustrated. Any help is appreciated.

Files not found when trying to access my music

This has happened several times since I got my first Ipod. Am about to give up on Itunes because of it!!!
I go to access my music and am told that over 95% of all my music has no files, they can't be found?!?!?!?! ***??????
Can ANYONE help??? I emailed Apple/Itunes directly over a month ago....guess what, am still waiting for an answer...

There can be a number of causes for not being able to access file form web browser. One, you might be writing to wrong directory. Two, you might not have sufficient privileges to either write to directory or overwrite files already in that directory. From your description, it's the latter of the two, so you need to get a hold of creative cloud support and get file/folder permissions fixed. Good luck.

After accessing a web site through a link I get the message file not found when trying to access it again.

This has happened on several sites. I have tried to access the same links through Chrome and do not have a problem there.

HT1923 did anyone get the apple application support was not found when trying to instal?

I am having trouble instaling itunes. has anyone got the apple application support was not found when trying to instal itunes? it looks like it is not installing all of files to my computer and it can not reach a certain folder

With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

Why does FCP error "File Not Found" when I try to open my sequences????

I recently updated all of my software and the following day I started getting errors "file not found" when I would try to open a sequence. Now all of my sequences are being lost and I am losing time and money because I can't meet deadlines! This *****!!! With one sequence I had to reedit the entire thing from scratch and when I did for some reason the old one would then open. But the next time I opened FCP both sequences would error out. Following the "file not found" the computer responds with another error "error: out of memory" What the devil is going on with this crap?

I seem to have figured out what my problem was. After trying to build the same project (that failed on the Mac Pro) on my laptop and encountering the same errors, I realized that the problem had to be with one or more of my assets and not my new version of FCP, since my PowerBook is running FCP 5.0.4 and my Mac Pro is running FCP 5.1.2.
In my case the "corrupt" file was a Photoshop PSD file. In the past (FCP 4.5) I was able to use PSD files with hidden layers. I would merge the visible layers into one layer, keep the hidden layers and save the file. Once in FCP, I imported the PSD file and kept right on truckin'. I've done this for years. For some reason now with FCP 5.1.2 (and 5.0.4), that's not flying anymore. Once I "Flattened" the PSD file in Photoshop (deleting all of the hidden layers) I was able to build the project without any errors.
Interestingly, the technique I used to figure out which file was "corrupt" also allowed me to salvage parts of some of my "lost" sequences. I saw this posted in a forum at Creative Cow (creativecow.net). Basically, I opened up the project, clicked the OK button after the File Not Found error, went into the Browser, right clicked on the offending sequence, selected "Make Offline". When I double clicked the sequence it opened in the timeline with all of my assets offline. Then in the timeline, one by one, I right clicked on each clip and selected "Reconnect Media". Once I linked up the media, if I didn't get an error message, I would save as a new project (to salvage what WAS working), and go to the next clip. I did this until I found the offending PSD files.
I hope this helps. Now it's time to play "catch-up"

I keep getting error code -43 not found when trying to load certain instruments. Any ideas?

Errors 3000-3999 (3004, 3013, 3014, 3018, 3164, 3194, and so on): Error codes in the 3000 range generally mean that iTunes cannot contact the update server (gs.apple.com) on ports 80 or 443.
Update to the latest version of iTunes.
Verify the computer's date and time are accurate.
Check that your security or firewall software is not interfering with ports 80 or 443, or with the server gs.apple.com.
Follow Troubleshooting security software. Often, uninstalling third-party security software will resolve these errors.
An entry in your hosts file may be redirecting requests to gs.apple.com (see "Unable to contact the iOS software update server gs.apple.com" above).
Internet proxy settings can cause this issue. If you are using a proxy, try without using one.

Keep getting Disc Burner or software not found when trying to burn a CD

I am not able to burn a playlist to a CD and get an error at the top of Itunes window "Disc Burner or Software Not Found". I have been able to burn CDs in the past with this same computer but had some issues with songs in itunes. Support had me uninstall Itunes and reinstall. I have also uninstalled the device in the device manager and re-installed it. I really don't know what to try except to ask for help here. I would appreciate any direction I can get. I have a Dell desktop XPS running on Windows 8.

Are .mp4 files not supported when trying to merge 2 videos into 1 video?

Are .mp4 files not supported when trying to merge 2 videos into 1 video? The steps in the manual seem simple enough. But the paste function won't work on the 1st video after selecting all and then copy on the 2nd video.

There are 9 different versions of iPhoto and they run on eight different versions of the Operating System. The tricks and tips for dealing with issues vary from version to version and OS to OS. So before anyone can help, they need information to work with. Things like:
- What version of iPhoto.
- What version of the Operating System.
- Details. What were you doing when the problem arose?
- Did it ever work properly?
- Are there error messages?
- What steps have you tried already to solve the issue.
Anything else you can think of that might allow someone else to understand your issue.

Be sure that all DLL calls are thread safe (do not perform calls in UI thread).
Also for real-time application you need real-time OS.
