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?

In the process of developing a function one typically has to change the number (and type) of parameters. This has to be done both for the function and the function declaration. Hence I would consider it useful to have an option 'Goto Declaration'.
Right now the IDE provides the right click menu 'Goto Definition', so if I change the declaration it is easy to jump to the function and adjust it accordingly. It would be nice if the reverse process would also be possible...
I want the batchbuilt window sizeable.
My cws consits of 51 projects, and the configurations-list is no longer useable. I just can see the project names, but not able to see the "release/debug/..." additional informations of the projects to be built. The list looks like
" c:/../../Task_AutomaticMeasurement.prj - D"
" c:/../../Task_FullAutomaticMeasurement ..."
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.
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
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.
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:
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)
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.
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 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.
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.
As suggested about two years ago (http://forums.ni.com/t5/LabWindows-CVI/Is-it-possi
Phrased differently I would like to have one more attribute 'SHOW_POSITIVE_SIGN' that could be set to
0: don't show the plus sign, i.e. display numbers as is implemented now, default
1: show plus sign for positive numbers
2: show plus sign for positive numbers and zero
it has been discussed a few times in the forum of how to implement a check box control in a table, e.g. here. At present, this type is not natively supported. In principle, as second best possibility, one could use suitable image controls, but the 'correct' image of a check box depends on Windows version, theme, etc. Hence it would be much nicer to have a native check box control - thanks
I have 2 suggestions for graph improvements.
1/ I suggested the first one a long time ago but it has never been implemeted so I try again trough this idea exchange board.
I would like to have the possibility to change the grid lines style to dash or dot. Today only solid is available.
I have written a routine to do it for printing graphs but as you can see it in the attachment it is not always working properly.
2/ It would be nice to have the possibility to set a percentage of transparency for the plots. In the example attached you can see if the green plot would have been behind the blue some parts would not have been visible. By setting the percentage of transparency of the blue one the green if behind the blue would become partly visible.
These 2 features are already available in the 3D graph so it would be nice to have them also on 2D plots.
There are several quests for better graph and UI controls, and I support them all
Now, I was very impressed looking at the new WPF Graphic controls of Measurement Studio 2012 and would like to have similar features in C (i.e.CVI), too.
So in addition of having classic controls and lab style controls may by one could also add this new scheme of controls...??? The graph control in particular looks very promising, with color gradients and polar plots, both frequently requested features, here realized in a new style. Wanna have...
For a fist impression, see here
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
