At present, the only option to jump to a panel callback is Ctrl-P shortcat from the UIR editor (or Code >> View >> Panel callback menu selection). Even longer is to generate a panel callback, which can only be done via Code >> Generate >> Panel callback menu chain.
I'd like to have added two options to panel context menu in the UIR editor: Generate Panel Callback and View Panel Callback, in the same way as those options are present in a control context menu; something like this:
When designing a UI it is sometimes necessary to have text composed of indices and superscripts, e.g. R^2, chi^2, ...
Right now this can be accomplished only by using several texts in different sizes and by manually aligning these text fragments. This is quite tedious
Hence I would suggest permitting simple control sequences to automatically have text parts in superscript, subscript, italics and bold within the very same text message (possibly similar to HTML)
This would make it a bit easier to edit an old project without the issue of upgraded UIRs because it might get loaded by the wrong CVI version and one edits and accidentally saves it before noticing.
Visual Studio installs a helper EXE which launches the right Studio for any SLN.
If MS didn't patent this , it would be a nice feature for CVI (and LabView?), too.
If you have, say, three controls called MAX_1, MAX_2, MAX_3 arranged vertically. If I select them all, copy and paste, the new controls appear as MAX_4, MAX_5 and MAX_6 but in the wrong order to what you would expect.
A similar issue occurs with assigning a group of controls to a control array, they always seem to be in the wrong order, usually reversed.
Even after using CVI for many years I still find the DirSelectPopup confusing, because it provides a file selector, displays files, and even allows to select files...
I would prefer an improved/modified function such that the DirSelectPopup only shows directories, does not provide a file selector, etc.... This should make it much more obvious that one is selecting a directory, not a file...
If the label area is fixed size (i.e. option "Size to text" disabled) and is higher than the font height, it would be useful to have an attribute to set the text vertical alignment:
Now the text can be justified only horizontally (left justified, centered, right justified)
I would like to have the possibility to store the uir-file not as a tui-file (old-fashioned ini file), instead as a xml file.
It has been suggested much earlier here, but obviously passed out of mind:
When using 'Go to Definition' (CTrl+I) while in release configuration, CVI tells that no source code information was found for the identifier '...', because 'Browse information is not available in the Release configuration'... (still true for CVI2010)
This can and should be improved!
And it might be a good opportunity to also add the reverse process, 'Goto Declaration', suggested here
Customer who has used CVI for years and likes it was looking a Mstudio for the reason that a lot of his new engineers can't or don't do the regular C programming. He likes Mstudio as an idea but, with the extra cost of adding MS Visual Studio and dealing with a they support/We support issues of having two SW pkg from 2 different companies gives him pause about purchasing. He stated he likes CVI because if there is an issue (even if rare) he know that NI will help to figure it out. I let him know I'd provide the feedback.
Please conisider supporting multi-touch screen gestures in a similar manner to the mouse events. Windows 7 Mulittouch capabilities are a good place to start. http://msdn.microsoft.com/en-us/magazine/ee336016.
The GUI of the future will most certainly be touch screens, and users expect to be able to use gestures such as pinch, fling, spread, rotate, etc.
The JIT debugger option in CVI 2010 is a nice step in the right direction, but only being able to debug builds that were compiled in "Debug" mode pretty much defeats the whole purpose of the idea. Debug builds are much too slow to be used in production and on my machines, if I ever use a Debug build, it probably already runs under the debugger anyway! Seeing that CVI is not even an optimizing compiler I cannot understand why release builds cannot be properly debugged.
Thing is, the crashes in production are the important ones that I absolutely need to be able to investigate, and CVI does not provide ANY assistance in this area apart from being able to at least generate a MAP file. This is what I currently have to do: I have included code in my application that creates a memory dump and sends it to me when the application crashes or hangs. This dump I can then load into WinDbg and with a few tricks I can at least import the CVI MAP file to get some functions names in the stack traces, but that's it, all investigations have to be done on the assembly level. To quickly decipher stack frames, e.g. to have a look at local variables, I often even have to throw my OWN code into a disassembler (IDA Pro)! I'm really glad that this way I am now at least able to debug most crashes at all, even when they happen far away in a different country, but this aren't the 80s anymore and you can probably imagine that this process is hard and time consuming and very much annyoing. With code compiled in VC on the other hand I can load a MiniDump and have a look at the stack trace, variables and code on the source level without much hassles.
Some ideas that could help:
- Let me (JIT) debug release builds
- Let me load MiniDumps into the debugger or
- create PDB files that I can use together with a debugger that can load MiniDumps (WinDbg, VS)
- Let me not only use an external compiler but also an external linker that generates PDB files for release builds (I don't like this solution as I use C99 features VC does not support, but I'm desperate here)
Okay, rant over for now, I think I really needed to vent a bit. Thanks for reading this far ;-)
All the best, Marcel
I noticed that LabVIEW has two ways to download instrument drivers: direct downloads from IDNET and through the NI Instrument Driver Finder.
[NI Instrument Driver Finder Menu Option Image]
[Alternative NI Instrument Driver Finder Menu Option Image]
When downloading drivers directly from IDNET, the file must first be unzipped and then placed in the <National Instruments>/labview xxxx/instr.lib folder.
The easier option when working with LabVIEW, the NI Instrument Driver Finder, downloads the files, unzips them, and instantly gives you access to example code or palette of VIs for communicating with said instrument.
If possible, could we add a similar tool to LabWindows CVI? It would be nice to have a menu option which would open a CVI Instrument Driver Finder.
The interface could then allow users to easily find a driver, download it to their Instruments Folder, see example code and start work.
Since probably 30% of all LabVIEW adoption comes from driver downloads and driver development, maybe this is an investment of resources worth looking into?

I would like to see an configuration of batchbuilt process. I have a big workspace with many projects; and would like to create different setups, like "compile only all server projects" or "compile all client projects". The workspace contains a big server-client -based software packages; some dll-projects used for server side only, some only client side.
sometimes it woud be useful to have plot symbols available that are larger than the fixed standard size. Hence I suggest providing a plot attribute ATTR_TRACE_POINT_SIZE where one could set the point size (e.g. in pixels)
sometimes vertical buttons or toggle buttons fit better to the rest of the UI than the standard horizontal buttons. In such cases I would like to have the possibility to have the button text aligned vertically. Hopefully the attached figure can explain my wish...
In the project window you can organize the project files into some "virtual" folders (Source Files, Include Files, ...)
If you right-click on the project name, you can add a folder with the item "Add Folder...".
If you right-click on one of these folders, you can add one or more files files.
But it's impossible to create a subfolder of one of these folders.
Every large project has a lot of files (sources, ini-files, images, icons, ...), so I think it's quite common having them saved into different "real" folders and subfolders. If you don't explicitly add these files to the project, you can add them to the distribution kit browsing your hard disk "real" folders, but in this situation the absolute path of the files is used. And if you move all your project from a PC to another one you won't be able to recreate the distribution kit without errors if you don't save the whole project to the same folder you use in the first PC.
And this is a really big problem.
For files explicitly added to the project, instead, the relative path is used, and this is OK, so the best situation is to add all the files in the project window.
So it's necessary create a full structure of virtual folders and subfolders.
My CVI application started to generate linker errors immediately after I upgraded from CVI 2012 to CVI 2013. A number of other people have reported exactly the same problem, with the linker unable to resolve symbols found in IMAQdx or nivision.
This means that the final release of the new version of CVI cannot have been tested when using the image acquisition or image processing add-ons.
I suggest that, in future, new versions of all tools are subjected to automatic regression tests against the examples distributed by National Instruments before release. Because it obviously doesn't happen now.
