I want to be able to do the following:

 

  1. Right-click on a control on my user interface and select “Add Event Case to Control Callback” (if a callback function already exists)
  2. CVI brings up a dialog similar to what you see at Code>>Preferences>>Default Events to select an event for that control
  3. Check the box for one or more events for that control, click OK, then
  4. Have CVI find the existing control callback function and add a case to the switch statement for each event I checked

If you haven’t written any code in the callback already, you can just change the default events and re-generate (replace) the control callback.

 

However, if you have already written code for one event case, the only way I can find to add an event case is to do it manually. I go to Code>>Preferences>>Default Events or use the Operate tool to look for the constant name of the event that I am interested in, then I go back to my code and manually type out “case EVENT_CONSTANT_NAME: break;” with the name of the event and hope I remember it correctly and spell it right.

 

CVI is all about minimizing user errors and reducing development time by, you know, not making you type things out yourself, so I think this functionality would be a useful addition.

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:

  • to the top
  • centered
  • to the bottom

Now the text can be justified only horizontally (left justified, centered, right justified)

Hi,

 

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...

It has been discussed a few times in the forum so it might be appropriate to also ask here for the implementation of a native polar plot, i.e. plot r versus theta, with radial grid lines and all the corresponding ingredients.

Summary:

Data Tooltip should also display the name of the function, when displaying the value of a function pointer variable.

 

Description:

While debugging a CVI application, when hovering the mouse cursor over a function pointer variable, the Data Tooltip displays the address of that function, referenced by the variable.

It would be very useful in cases when you have multiple function pointer variables referencing several different variables, to have the Data Tooltip not only display the address of those functions, but the name of the functions as well.

I noticed that LabVIEW has two ways to download instrument drivers: direct downloads from IDNET and through the NI Instrument Driver Finder.

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?

As discussed here and here, CVI does not re-open workspace files in the order they were when CVI was closed; I am referring to confined workspace, not freely floating windows.

 

As a result, starting CVI one first has to locate all the files, where did the include file go...? If you happen to have some more tabs this is a waste of time.

 

Also, as Roberto mentioned, you can not easily use the short cut keys Ctrl-1 etc. because of the changing assignment.

 

So, in short, I am asking to improve this behavior and maintain the tab order of CVI workspace files, that is, re-arrange/re-open the tabs in the order they were when CVI was closed.

 

Thanks!

Over the years the look of CVI's control elements got closer to native Windows controls, e.g. by the direct use of native Windows controls such as the File Select Popup, which I would consider a welcome visual improvement.

 

What still is not available is a control element providing a Windows-like status bar, e.g. like the one of CVI's IDE.

 

I imagine a status bar which is similar to use as a menu bar, i.e. with a LoadStatusBar command, similar editing capabilities and the possibility to define the number and type of elements (text, image,...). Also the lower right part should resemble the typical Windows 'triangle', see figure below.

Thanks!

Hi,

 

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)

Hi,

 

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.

I add this new idea based on the info on this thread.

I know that this idea is almost the same, but the basic reason is quite different.

 

I think that C++ offers much more flexibility for the development and it is a much more powerful approach for the future.

Now CVI uses CLANG/LLVM compiler, that is a C/C++ compiler.

But, as written by Luis from NI

Supporting C++ entails far more than just the compiler. For example: the standard C++ library (including templates, etc...), the APIs of all the standard CVI libraries, the source editor (auto-indentation, coloring, etc...), code-generation from the various wizards, memory runtime checking, debugging, etc... so, even though the compiler does support it, for all of CVI to support C++ is still an extremely large undertaking that has to be weighed against other, competing work that's going into CVI.

 

 

CVI currently jumps to the first entry in the build output window, whether this is a warning or an error. I'd like to suggest an option to see the point of the first error, if there is any, before any warning. Maybe they could be color coded, too. When starting a new project I usually place some TODO messages (#pragma message) and if this is in a global header file I always see this and not the build error.

Using CVI 2010 you can create different Custom Configurations

But I think that if a developer creates a new Custom Configuration (debug or release, x86 or x64), he wants to distribute it to a target machine. I don't create a Custom Configuration to have it run on my developer machine!

I've already asked to NI Support, and this can't be done in an automatic way.

 

So I suggest a new feature in the "Edit Installer" window to specify which Configuration (Default or Custom) to include into the installer (see attachments)

Hello,

 

following the discussion here I suggest to (more clearly) indicate the number of allocated rows and columns in the UI table editor.

 

I imagine something like

table-editor.png

 

where the left number indicates (as now) the currently selected row, and the right number (11 in my quick example) indicates the number of all table rows.

 

The same might also be added for the number of total columns.

 

Thanks.

It has been suggested earlier (here) to provide the LabVIEW feature of a display format 'SI notation' allowing to directly enter 100 kHz (instead of 100000 or 1e5)

In CVI 2013 the array display has changed (for the worse, in my opinion).

 

There are two minor inconveniences and one acute shortage I would like to see improved (hopefully prior to CVI2020 Smiley Wink)

 

First, the right click context menu: If I want to see values of a numerical array, it offers a 'Graphical Array View' but no 'Array View', so one first has to chose 'View Variable Value' and then 'Array Display' - maybe one could save one step and already provide the 'Array Display' in the first case...?

 

Second, the new Array View table still is very slow, not extremely slow as prior to SP1 but still very slow...

 

Most importantly, at present it is impossible to debug large arrays, large meaning arrays with more than 10000 elements. The current implementation requires to select a slice of data - but this makes it impossible to check or compare say array indices 5, 10005, and 20005...

Of course I agree that there is no need to simultaneously see more than 10000 data values - but why not have a table with say 100 rows that can be turned over, e.g.  displaying either elements 1-100, 101-200, ... this way one could access and inspect all array values...

As suggested by Daniel (D-Cubed) an improved version of GetCVIVersion is needed in order to determine the patch level programmatically. Right now, no simple approach exists for an executable to determine if the CVIRTE is a patched version or not. For example, GetCVIVersion returns 1300 both for the patched and the unpatched 2013 release.

 

Thanks.

Right now it is possible to set the color, and since CVI 2013 also the line style, of all grid lines collectively.

 

I would like to distinguish between major grid lines and minor grid lines, e.g., draw major grid lines with dashed lines / light grey, and minor grid lines with dotted lines / dark grey.

 

Thanks!

 

 

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.
