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.

As of CVI2013 data tooltips and variable view do some kind of automatic rounding but based on 15 digits only... This prevents tracking numeric / rounding issues. Unfortunately, no possibility exists to show the full precision of doubles... Phrased more drastically one you cannot use CVI to debug numeric issues...

 

So I suggest to urgently add

 

 

  • as a minimum version the possibility to show true numbers, not rounded numbers, allowing true debugging
  • as a more general version the possibility to adjust the precision of displayed numeric values

                 

 

CVI currently provides a way for alligning controls (using the dotted matrix). But, with large UIs, this method is inefficient and users must align controls over large distances by hand from the Property Browser. I propose an upgrade that would help users achieve alignment by drawing lines that unite the control being moved and any other control that happens to be close to alignment with it (Figure 1).

This feature would increase usability and productivity (which seems to be decreasing by increasing the size and complexity of UIRs).

Hello,

 

The current features of the UI editor with respect to editing tooltips are VERY limited. I am not complaining because one has to start somewhere Smiley Wink

Instead I am adding yet another suggestion on this subject Smiley Happy

 

Please provide the possibility to enter tab stops, see my comment here

 

Because this is such a modest request, please also consider this one Smiley Wink

 

THANK YOU!

Starting from CVI2010, the User Interface Browser and the Attribute Browser are both located on the right of the UIR editor in the Workspace window.

 

I'd like to be able to hide these windows when required: when working on small screens like when you use a laptop these windows occupy a lot of space even if you reduce their size at the minimum.

 

In addition, the ability to choose which window to display on the bottom left could be a good option: up to version 2009 the bottom left side of the workspace window switched between the library tree (source editor) and the attribute browser (UIR editor).

 

Ideally, while in the UIR editor I would like to be able to:

  • Choose whether to show some window on the right side or not
  • In case nothing is shown on the right, choose whether to have the attribute browser, the library tree or the user interface browser in the bottom left angle

Hello,

 

this is a minor issue but still it can be very inconvenient... Very inconvenient because it almost always happens to me that if editing a menu bar I inadvertently mess it up. This is because if one is inserting a new item or child item, after pressing the 'Insert Item' or 'Insert Child Item' button the active control is set to 'Constant name', see below.

 

item name active control.png

 

 

But I am never editing the 'Constant name' but always the 'Item name' (and callback function, modifier key...). Hence I almost always start typing the item name until I realize that I was editing the wrong field.

 

So my suggestion is to consider changing the active control after one of the insert buttons has been pressed to 'Item name'.

The active configuration (Debug, Release, custom ones, ...) is shown in the bottom-right corner of the status bar (see attached config01.jpg).

I think that it would be better if this would be a menu ring that can be used to change the active configuration, without having to select Build >> Configuration >> xxxx (see config02.jpg)

Hi,

 

Almost all function keys found on my keyboard have a corresponding keycode that can be used e.g. in FakeKeystroke () - except 'Print Screen'. It's not obvious why this one has been left out, it would be convenient to also have support for this key, e.g. for generating a screenshot or a printout.

 

Thanks.

Personally I don't like the "unsorted" look of the libs as it is now. I always create a libs branch and put them there. This way the branch can be collapsed and saves space I don't have to scroll when having multiple projects in one workspace. Libs are files I don't edit that often so I don't have to see them all the time.

For every other file type CVI "knows" at the Add Files to Project sub menu, there is automatically a branch created - but not for libs.

When using the UI functions, a neat feature is the ability to pull up a dialog of valid control IDs when specifying the control:

 

1.png

 

clicking the elipses displays this dialog showing all valid control IDs:

 

2.png

 

If you are using the function panel however, you cannot access this dialog and you are on your own for figuring out the correct control ID:

 

3.png

 

I think we should add this functionality in the function panel for any function that has a control ID parameter.

 

 

Currently when formatting hex values into strings the letters a-f are always lowercase.  It would be nice to have an option to make them uppercase, as that is how most people are used to seeing them.  It would also allow for consistency between the way numeric controls work (which use uppercase A-F).

 

 

When building a project consisting of many files it would be much more convenient if the Build Output would jump to the line with the first file showing an error (or, if no error occurred, to the first warning).

 

Right now, if there is a build error I have to scroll through the (possibly long) list of files to see which file produced the error; only then I can click on the error message to have the IDE highlight the problematic line.

 

Thanks

Hi,

 

Currently, when a CVI application is deployed on a PC with a DPI setting different than the development machine, the application will generally not look like how the programmer intended as the fonts get resized while the other UI elements do not, leading to overlapping text, awkwardly resized controls, etc.  One way that DPI scaling could be implemented in CVI would be to use the same functionality as the 'Scale Contents on Resize' option for panels, where internally CVI could resize the panel and use this scaling to rescale all the UI elements (including fonts) on the panel to the appropiate size per the Windows DPI setting.  This would make the panel look a lot closer to what the programmer intended and would generally make most applications usable with different DPI settings without any additional work from the programmer.  Per my other suggestion, I would request that the programmer has the capability of disabling this functionality so they can handle DPI scaling themselves should they wish to do so.

 

Thanks.

What is differnce between the forum and the knowledge base ?

As far as I see the forum is where users ask questions and answers are provided, often by NI representatives.

The Knowledge base appears also to be where questions are aksed have solutions provided.

 

This means that I could search the knowledge base when the same question/solution is in the forum and vise-versa. Can these be in some way combined with a better search function .

 

It would also be useful to remember search location based on user login - The amount of times I end up with a solution using LabView (I do not use and hopefully never will use Labview).

 

 

As CVI evolves (in age and functionality) I feel that additional efforts are required for maintaining the product, i.e, keeping it 'consistent' and avoiding a 'mosaic look' as if assembled by different engineers in different decades... Smiley Wink

 

A simple example but also one I would like to see resolved is entering data types in the UI editor vs in a function call (PlotIntensity in this case):

 

 

edit_numeric.png      plotintensity.png

 

So, for example, long long translates to int64...  Why not simply use the identical terms??

 

I agree it could be worse but I also feel that this is a valid suggestion for future improvements...

Attaching controls to a splitter in the UIR editor can be a pain if the panel has several controls on it. I'll make an example using CVI example SendMail: trying to add a vertical splitter and attach all controls to it in order to rearrange the panel when the user resizes it. This is the original panel, you can see the vertical splitter in the upper right corner:

 

SendMail.png

 

 

First of all, if several controls are selected, they overlap in the right panel of the editor in a way different from the original panel. Here you can see that the decoration indicated by the arrow overlaps two string controls that I'm not able to operate on to select desired  attachment mode. This means that I need to proceed to attach controls in steps, hoping new controls added are not overlapped by previous ones. Alternatively I can move controls in the right panel to encover hidden ones, but this ingenerates confusion as controls are no more in the original position besides being a waste of time.

SendMail_Overlap.png

 

Second item: if selected controls are on the "wrong" side of the panel, they are all grouped (and possibly overlapped) on the closest boundary of the right window. See this example: Send and Quit buttons are only partially visible on the lower left corner of the right window and additionally they are overlapped (in the small box how they appear if I select one of them and move it upwards):

SendMail_Arrangment.png

 

 

I suggest that this function is improved with these additions:

 

  • Honour the z-plane order of the original panel when controls are selected for attachment and moved to the right side
  • Maintain original controls position when moved to the right panel. Consequently:
  • Have both scrollbars enabled in Controls on the Splitter window in order to navigate to the controls; at present only one of them is enabled, whether vertical or horizontal depending on the type of splitter

Hi Everyone!

 

In these days, I have been debugging a complex application(almost 12,000 lines of code) and it was very hard to do a map showing the relationshing at least of some critical functions.

 

For this reason, I consider that a very helpful debugging tool could be to add in LabWindows/CVI, a window like the VI Hierarchy in LabVIEW; that shows the relationship beetween the functions inside all the module in a CVI project. This windows will show which functions calls a particular function.

 

Here, there is a very simple example:

Hello,

 

usually I work on my projects on two different computers (home/work or development/lab). I would like to see a possibility to more easily move my project back and forth, say by providing two new menu commands

 

File / Import Project and File / Export Project

 

I imagine that the Export command generates a zip file consisting of all files required to build the executable (and a distribution) and also exports the editor preferences (probably without the window positions because different computers may have different screen resolutions) etc. The Import command then should load the *c., .cds, .cws, *.fp, *.h, *.prj and *.uir files, import the editor settings, adjust the library menu and load any instruments.

 

Thanks!

Hello,

 

right clicking in the source code brings up a popup menu, see below.

 

Some of its items are dimmed or adapted to the context. For example, 'Format File' versus 'Format Selection'. This is nice and as I would expect it for a context menu!

 

Unfortunately, there are some entries that are available even if they are more ore less superfluous.

 

For example, 'Edit DAQ task' shows up even if no DAQ is installed. Selecting this menu entry only shows 'This feature requires DAQmx' - so why not dim it if no DAQmx library is available?

 

The same is true for 'Edit IVI Specific Driver Attributes...' and the IVI library.

 

But also 'Recall Function Panel', 'Browse Identifier' and 'Find UI object' don't care about their context.

'Open Quoted Text' for example, does! (which is good)

 

So I would suggest to have the popup menu act more consistently and only provide commands that are meaningful.

 

Thanks

Hi,

 

just a little idea for a minor improvement of the status bar: Right now, the coordinates of UI controls are displayed in different ways: in the popup window, the sequence is Top Left, while in the status bar the sequence is Left Top - this is somewhat irritating...

 

So I'd suggest to change the status bar text from

 

(23, 873) to something like

 

Top: 873 Left : 23

 

Thanks.
