Labview 8.5 error on save: "Cannot load help information of [filename]."

Hi all,
 
 I was working on a VI in Labview 8.5 when the program (Labview) crashed. When I relaunched Labview it asked me if I wanted to recover the VI I was working on, I said yes and the recovered VI runs fine, but I cannot save it. When I try to Save or Save As I receive the following error message: "Cannot load help information of [Filename]" and my only option is "Cancel Save". If I click "Cancel Save" Labview returns a "File not Found error". Until the recovery, I could and did save the file with no problems. It now seems that I am locked out of the file. 
 
  I have a backup, but it is does not contain the 2-3 hours of work I put in before the crash. Does anyone have a work-around, or know the source of this error? This is the second time I have seen it on a recovered file (the first time I had a fresh backup, so it wasn't a big issue). 
 
Here is a dump of the "Referencing files in the project or its dependencies" from the Save As dialog:
 
[Project Name].lvprojreplay2-offsets.vi:Instance:6replay2-offsets.vi:Instance:5replay2-offsets.vi:Instance:3replay2-offsets.vi:Instance:2replay2-offsets.vi:Instance:4replay2-offsets.vi:Instance:1replay2-offsets.vi:Instance:0
 
Thank you,
Tim

I'm having the same problem. I came here to see if there was any information about this problem, and found the previous message. Lucky for me, I'm not going too lose more than about 15 minutes of work.

Take care,

Does anyone know if there is a way to clone a vi from memory to disk? That would be a good work around for me, or anything else you might suggest. It's not a big deal, as long as the computer doesn't crash before I finish this specialized project, I would just like to save my new work. I have no idea what the "help file" refers to, i've tried linking a help file to the vi and then saving but it still doesn't work... What a strange problem.

Hi Tim, One relatively simple but effective method to recover data from a corrupted VI is to "cut and paste" your block diagram to a fresh new VI. I have used this method many times in the past, and it has worked well. Just select your whole block diagram, choose copy from the edit menu, and then choose paste from the edit menu in your new VI.

&nbsp;Thanks for the tip, this is what&nbsp;I ultimately did, but the "Select All" doesn't quite select all, so it was a bit tedious.

How can I modify the &quot;Type definitions&quot; of &quot;Function Prototype&quot; if I want build a DLL in Labview 8.5.1.?
Hello,We have a library with several VIs (API - Interfaces to our Real Time Target). This VIs we provide to our customer to generate own VIs to control the Real Time Target.Now we want to provide the functionality of this VI-library as DLL to our customer. The problem is, that labview use self definite name of type definitions. Also if I use "strict Type definition".Example:void GetOutputValues(VARIANT *Scale_In, int32_t ModelNr, uint16_t SignalID[], TD1:smileymad: *errorIn, VARIANT *Scale_Out, TD2 *Data, TD1 *errorOut, int32_t len)It is possible to modify "TD1" and "TD2"? I want to give useful names.GreetingsSteffen Hi Steffen, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Try&nbsp;editing the .h file as follows: CHANGE FROM: typedef struct {&nbsp;LVBoolean status;&nbsp;long code;&nbsp;LStrHandle source;&nbsp;} TD1; CHANGE TO: typedef struct {&nbsp;LVBoolean status;&nbsp;long code;&nbsp;LStrHandle source;&nbsp;} TD1; typedef struct {&nbsp;LVBoolean status;&nbsp;long code;&nbsp;LStrHandle source;&nbsp;} LVErrorCluster; then your GetOutputValues prototype becomes: void GetOutputValues(VARIANT *Scale_In, int32_t ModelNr, uint16_t SignalID[], LVErrorCluster *errorIn, VARIANT *Scale_Out, TD2 *Data, LVErrorCluster *errorOut, int32_t len) If your source-code doesn't refer to "TD1", then&nbsp;you probably won't need to keep the TD1 prototype!

Memory is full during &quot;Save As&quot; of LabVIEW 8.5 project
Good Morning All, &nbsp;&nbsp;&nbsp;&nbsp; Have run into a weird issue while trying to rename a LabVIEW 8.5 project. I've got two projects that ended up having the same names (one by me, one by another engineer). I want to open both at the same time, so I figured I'd open the one and do a "save as", or a "rename". The first time it started processing, doing file loads, and then hung looking for a sub-vi, with the search address pointing to the .llb in the LV 8.5 directory where I manually located it. Once that was resolved, and the original project saved I tried again. This time it did a bunch of loading and then gave me an error box with the message:&nbsp; "LabVIEW:&nbsp; Memory is full.&nbsp; Cannot save project 'original project name.lvproj'" This isn't a big project, the machine is a new HP Compaq dual core 2.8GHz with 1.5Gb of ram, so I don't really think that it should be generating anything that big. This happens with either a "save as" or "rename". I ended up just changing the names of the .lvproj .aliases files to the one I needed and it seems to load ok, but it would be nice to understand what is happening here. &nbsp; &nbsp; This is interesting behavior, since NI actually ensured that you would now have the ability to Save As and Rename a project with the <a href="http://www.ni.com/pdf/manuals/371780c.pdf" target="_blank">release ...

Adding an &quot;IMAQ Image.ctl&quot; to the &quot;Display State.ctl&quot; of an XControl prevents LabVIEW from creating a probe of &quot;Display State.ctl&quot;
I am working on an extended IMAQ Display control using LabVIEWs XControl capabilities. &nbsp; I need a copy of the original image passed to add some overlays which must not affect the original image. To achieve this I am creating a backup image in the "Init.vi" and deleting it in the "Uninit.vi". I am storing the reference&nbsp;of this image&nbsp;in the "Display State.ctl" which is part of every XControl. &nbsp; As soon as I am adding an "IMAQ Image.ctl" to the Display State cluster, it is no longer possible to generate a probe of the Display State cluster for debugging purposses. I am always getting the message: "Failed to load or create probe." Deleting the "IMAQ Image.ctl" from the cluster makes the probe working again. &nbsp; Is it a bug or am I doing something wrong? &nbsp; I am working with LabVIEW 8.5 and Vision 8.5. &nbsp; Regards &nbsp; Ingo Bartsch Hello Mr. Bartsch, is it possible for you to post a small example to reproduce the behaviour?

Why do I receive a&nbsp; "Fatal internal error: "fpsane.cpp" line 399" when saving my VI? &nbsp; Thank you. Gustavo Hi Chris, But I could not solve the error that way. Actually, Labview is crashing with this error at any time when I am writing my VI. It simply crashes even if the VI is not running.

I have reinstalled Labview three time already and the error continues. Any other ideas? Thanks, Gustavo hum... not yet. &nbsp; I reinstalled LAbview 8.2 for the 3rd time... nothing happened. The VI I am trying to run is the example 4128.vi we can find in the forum. It is still crashing with the same error when I try to save or save as... or sometimes before the VI starts to run when I do any alteration. I think the error might be related to saving the VI.

How can I convert the &quot;AI one pt&quot; symbol from LabVIEW 6.3 to LabVIEW 8.0?

To make it completly clear: The block you refer to as a symbol is a VI belonging to the Traditional NI-DAQ driver. Currently there are two drivers for DAQ boards: DAQmx (the new one) and Traditional NI-DAQ (the old one). Since your VI was written in LabVIEW 6.x (6.3 never existed) the VI uses the old driver. What you need to do is: install Traditional NI-DAQ on your PC to get the support VI's for the driver in LabVIEW.

Labview crashes on loading &quot;missing&quot; subvi
Now that I'm confortable with Labview 8.5's&nbsp; projects explorer, I've been cleaning up my old vi's, and putting them into projects and library's.&nbsp; This meant that many vi's got renamed or moved, so I had to update those locations in some programs. &nbsp; During moving in the project explorer, I had a few unexpected crashes.&nbsp; It seems that moving/renaming doesn't always work properly...&nbsp;&nbsp; I've solved those issues by hand, didn't try to search for a reproducable error condition... &nbsp; But now I'm updating the toplevel vi's that make use of those renamed and moved subvi's,&nbsp;and I'm getting more crashes...When loading the top level vi, it asks for the location of the renamed/moved vi's.&nbsp; So I browse to it, and select the correct vi's.&nbsp;&nbsp; Works for about a dozen vi's, and then Labview suddenly crashes.&nbsp; I've tried ignoring that missing vi, but then it crashes somewhere else.&nbsp; So I decided to simply ignore all missing vi's.&nbsp; That worked,&nbsp;it then loads without crashing, and ofcourse shows lots of missing vi's with questions marks.&nbsp; I then manually, replaced the ?-vi's with the correct ones.&nbsp;&nbsp; Took a little, but now the program works.&nbsp;&nbsp; I can run it without problems, so I saved it, and thought I was ready.&nbsp;&nbsp; &nbsp;...

Do i have to use event structure on Ctrl + H buttons???:smileyindifferent: Please suggest some solution.

Re: Help, rather stuck: Should it take 22 ms to (via Visa) write &quot;ISET 2&quot; then &quot;ISET 0&quot; to an instrument? (to a Kikusui electronic load if you're curious)
Dennis hi: I hope you are able to gime a hand with KIKUSUI PLZ-30F electronic load. 1. I'm talking to the instrument via GPIB and it communicates. 2. It doesn't respond on a settings commands - change from CC to CR mode, etc. 3. There are 3 modules in a frame - one master and two slaves. 4. I'm suspicious I'm missing something, and... this company does not have techsupport...??? 5. Their drivers have entirely different format from SCPI and I have no use to them. 6. There is an IVI driver - but I didn't try it yet. &nbsp; Best, Oleg Finodeyev ...
