I recognized it's not possible any more to view a constant while debugging since CVI 2015.

Example: #define CONSTANT1      1

For example if I have a constant defined, I can then right click “view variable value”.

Normally CVI then shows me the value.

 

Since CVI 2015 this doesn’t work anymore. I also tried with CVI 2017.

In our code we use many structs where the fields are defined by a constant.

Now when the debugger can’t view the constant any more it also won’t view the value of the struct.

Example: #define CONSTANT1      1

Int struct[10];

struct[CONSTANT1]  = 5;

 

This is the main reason why I didn't upgrade from CVI 2010 to 2015.

  • Usability

If a file is listed in a project, but it is doesn't exist anymore on the filesystem, CVI doesn't mark it in any way in the project tree.

If the file is an .uir, this brings to a strange behavior with "Find UI object" (see here).

I think that files non-existent on the filesystem should be marked mark in some way (color, special icon, ...) in the project tree.

The check can be done when the user opens and closes the project.

  • Usability

The integration of some SCC software is officially supported in CVI (see this KB).

Unfortunately GIT is not officially supported, but its popularity has been increasing very much.

LabVIEW has a specific User Group in the community (Git User Group) and I think CVI should support the same integration

Hello,

 

it was very nice to see clang updated to version 3.3 in CVI2015; I wish this support of current versions of clang will be continued in the future, so I am hoping that with CVI2017 we might get clang 3.9 or 4.0 because of the following issues:

- many many bug fixes in clang

- improved diagnostics

- support of C11

- full support of OpenMP 3.1 and beyond

 

Thanks!!

Hello,

 

because I had installed CVI2010 on a brand new Windows 7 machine, I was curios to find out about all the service processes running on the system.

It seems that there are quite a few NI services that start after log-on. Some of  them seem superfluous, such as the Lookout Citadel service (no LabVIEW, no Lookout installed), but due to the lack of any information I did not bother trying to stop them

 

Suggestions:

1) NI should critically review the services and only start the services that are absolutely needed.

2) Services that are optional might be selected by a checkbox during installation or from the Options / Environment setting

3) NI should provide some documentation / explanation of each service and why it is needed.

 

Thanks!

Hi,

 

there has been the valuable suggestion of a "Picture and Text" button allowing more modern buttons.

 

For all those focusing on programming instead of UI design it would be also nice if CVI could provide more default buttons ready to use as some examples shown in the image below (taken from the NI community).

 

As they seem to be already available in LabVIEW it shouldn't be much effort for NI to adapt them to CVI... - hopefully Smiley Wink

In the last few years JSON came out as new format for data objects consisting of attribute-value pairs, largely replacing XML.

LabVIEW has functions to handle JSON data, and LabVIEW Community has been developing a JSON Toolkit.

In the CVI board of the forum this is the only result for a "JSON" search (at the present).

 

I suggest to integrate into CVI a JSON library (for example JANNSON).

I think this is better than develop a proprietary library.

Summary:

Display more struct member information during source editing and during debug.

 

Description:

While editing source code, CVI only displays the struct members, but no information regarding the type of the member (or declaration information, line file and line).

Add a tooltip to the right of the pop-up displaying the struct members in the source editor to display this information. Similar to this picture:

struct.jpg

Also add support for displaying nested structs and even display the member values while debugging, in form of a tree, when execution is suspended (CVI currently only displays the memory address of that struct variable).

 

Under labwindows CVI 2015, I develop a program using a state machine. For this I use a "switch".
The program is voluminous, and in order to browse it more quickly, it would be very interesting to allow the collapse and the expansion of the boxes in a structure "switch"

  • Usability

At present, autoscaling works with respect to the full provided data set, i.e. if all data are shown on the graph.

 

If say the X axis is set to manual scaling such that only a subset of all data is plotted, autoscaling of the Y axis still considers all data even if they are not shown, see the discussion here.

 

Hence it is suggested to provide an additional auto scaling mode which considers only the data actually visible on the graph, say VAL_AUTOSCALE_VISIBLE_DATA, complementing the current VAL_AUTOSCALE which actually is a VAL_AUTOSCALE_ALL_DATA

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.

Hi,

 

The CVI runtime engine calls the Windows API function SetProcessDPIAware() that tells Windows that the application is DPI aware in Windows Vista and later.  This seems to be forced upon all applications built with CVI, whether they are actually DPI aware or not.  Most applications built in CVI using the default tools are not going to be DPI aware out of the box, and setting Windows to another DPI setting than what the programmer used to create the UI will cause many graphical glitches and possibly make the application unusable.  The purpose of this request is to suggest to NI that the CVI Runtime Engine not call SetProcessDPIAware() so that the programmer can handle (or not handle) DPI scaling as they see fit.  If the programmer does nothing, the application will then, by default, be scaled using Windows DPI Virtualization.  This is not optimal, but it would leave the application usable and looking like how the programmer intended.

 

This is per this discussion here:

http://forums.ni.com/t5/LabWindows-CVI/Forcing-DPI-Virtualization/td-p/3079742

 

Thanks.

In earlier versions of CVI source files needing compilation were marked in a different color, unfortunately this feature has been removed in CVI2013. The suggestion is to re-introduce this feature...

 

Benefits:

Changing an include file immediately shows affected source files

It's always clear how time-consuming it is pushing the RUN button, i.e. if there are files *and how many) to be compiled first

Following this idea already implemented, it could be good to add up/down keys to rows and columns selectors.

 

At present, if the table is in hot or normal mode you can click on a cell in the table preview in the Quick Edit window to select the corresponding row/column: going to editing them is made easy this way. However, if the table is in indicator mode you cannot click on the cella to select row and column. The same applies if you want to reach a column/row out of visible area of the table: the only solution to that is to double click on the column or row selector and type in the number you want. Not easy  nor fast, and prone to errors. Much better to click on a button and increment / decrement the active column index

 

I'm thinking to something like that:

While developing code, having correct indentations is very helping in making sure you have all the right brackets and to see where your structures are nested easily.  Sometimes, whether by copying and pasting or just rapidly getting out a section of code, a whole segment might have incorrect indentation, which is tedious to correct.

 

This is where an auto indent tool could be a big time saver.  From somewhere like the Edit menu, where similar functionality is located in other development environments, you could select Format Selection to do a highlighted section or Format File to do the whole file.  Then, CVI can format the tabs for you:

 

autoindent.png

 

Although this is a simple example, auto indent becomes even more useful when you have multiple nested structures and decide, for instance, to add or remove another nested loop.

  • Usability

support of Unicode character set would be most welcome

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!

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...

I have had severe problems in development, due to a high synergy between my lack of attention and CVI behavior in search/replace dialogs.

I am talking about the fact that Find/Replace parameters [namely search directories] are stored at REGISTRY level, so that they remain the same across different workspaces.

Having to work with different version of the same software product, I have found myself looking into the wrong sources, or even doing mass updates, due to the fact that different projects have identically named sources and includes, just in different directory trees, and rapidly switching from one workspace

to the next I didn't "mind the step"

My suggestion, thus, is to store find/replace parameters at workspace or project level, so as to avoid the aforementioned inconvenience

This issue is that old that we all forgot about it... Smiley Wink

 

But this thread brought it back to my attention and I'd like to suggest two improvements:

 

Setting the width or the height of a control does not always succeed because there are limitations concerning the minimum and maximum size.

 

Suggestion 1:

 

If a function fails it should return a warning. However, calling e.g. status = SetCtrlAttribute ( panel_handle, PANEL_RING, ATTR_WIDTH, 5 ) returns success (0) even though the width of the ring control will be much larger than 5 pixels. For checkboxes, the situation is even worse because checkboxes are drawn right aligned to a transparent rectangular frame. So calling status = SetCtrlAttribute ( panel_handle, PANEL_CHECKBOX, ATTR_WIDTH, 500 ) will result in a transparent drawing rectangle of width of 500 but with the checkbox size remaining at the default size. Since the checkbox is drawn right aligned to this transparent frame the checkbox eventually may disappear from the panel (setting the width to say 10000 will not draw anything).

 

Suggestion 2:

 

Complement the documentation, the idea is given below:

 

Constant: ATTR_WIDTH
Data Type: int
Description:  The width of the control body in pixels.
Valid Range: 0 to 32767
Control Type Restrictions: Not valid for controls of type CTRL_VERTICAL_SPLITTER and CTRL_VERTICAL_SPLITTER_LS

For checkboxes, the minimum size is ... pixels, and the maximum size is ... pixels.

For ring controls, the minimum size is ... pixels.

...
