Save window position of Array Display

Debugging code involving arrays is complicated by the facts that

In order to view a value from an array one has to press first Shift F7 and then F4: one key press would be simpler Right now only graphical array view has its one click shortcut...
Every time I restart the program I have to reposition the array display window to a place where it does not overlap with source code window, variable window,... It would be much more convenient if the window position of Array Display could also be saved such that in the next run and pressing Shift F7, F4 the window would be usable immediately, without the need to reposition it

Thanks!

"tagfile" - ini file management

Here is the code of a kind of library "tagfile", I developed more than ten years ago, that I maintain and I always use for the management of my configuration *.ini files.

That works under Windows (CVI) or any UNIX system.

The code enables:

to read and write tags
to list the sections of an ini file
to list the tags of a section
to trap the errors

Most of others ideas about this issue on this blog are written under LabView ; I think a pure C code could be useful for some developers.

Comments are written in French but could be easily translated by any web AI API.

Below are example of functions for reading and writing a ini file. These functions are extracted from a program devoted to the dynamic excitation of a structure (mechanics).

.editorconfig support

At present, when you double-click on a .cws or .prj file the most recent version of the CVI IDE is launched with the selected .prj or .cws file loaded.

However, both project and workspace files include the release of CVI they are developed on, so it would be possible to search in the system whether that release is installed and open it instead of the most recent one. This is crucial when you need to modify a program already deployed to a customer but do not want / is not possible to update the target machine configuration installing a newer Run-Time module than the one already installed.

At present you have no control over this event, but consider also that in case you make modifications to the UIR files also, it may become difficult to revert to the original IDE format; for this reason when I need to update an old program I need firstly to open the project file in notepad to see which CVI release to use for this.

If automating the launch in the correct release is not possible, at least issue a warning stating the difference in the IDE release used with respect to the original one.

Hello,

I have a very elaborate Front Panel, developed in LabVIEW 8.6, which I'd like to import into my LabWindows/CVI 2013 development environment.

The background is that the new company colleagues are very proficient in C and want to use LabWindows/CVI to re-program the current state of the software and maintain and update only using LabWindows/CVI in the future.

This would be very usefull, since it would save a lot of time and keep the naming of the elements in the front panel as-is. For the customers it would mean, having the same tool they are used to work with and receive much faster and better service when it comes to changes or additional functionality.

If there is already a way to do this I'd be happy to have a step by step guide.

According to the feedback from the forum, this still doesn't exist. (http://forums.ni.com/t5/LabWindows-CVI/Can-I-convert-a-LabVIEW-Front-Panel-into-a-LabWindows-CVI-User/td-p/3044003)

In CVI 2013 is option “Run -> Attach to Process…” and new is option “<< Running >> -> Detach from a process” during debugging, which is very good to debug TestStand sequence and CVI DLL, advantageous if I need to update CVI code and do not have to launch TestStand again and again after new CVI code is builded. Hovewer, to attach CVI DLL to a process is always necessary to do next steps: Run -> Attach to Process…, then select process from a list (seqedit.exe) and click OK. I would appreciate similar option as “Specify Executable to Debug…” or key shortcut to attach process directly to TestStand in one click or using simple key shortcut.

What is the point of this Idea Exchange, when there is such a low uptake rate from NI?

There have been many very good suggestions posted here, but only 6 are labelled as "In Beta", which I assume means will be in the CVI release this autumn. There are 106 "Under Consideration", but there is no indication what is required to move them to "In Beta". For instance, Wolfgang posted "Reduce and document the NI services running after Windows logon" on ‎04-01-2011. It went to "Under Consideration" on 08-15-2011. Two Years from the original posting, we still have nothing!

How do I justify renewing our Volume Licence Agreement when the LabWindows development effort within NI is so small?

How many people actually are on the full time LabWindows team within NI?

make Window menu modal

In the CVI IDE the Window menu provides a list of View options, e.g. the Find Results.

While it's possible to display a window via selection of the corresponding menu item, it's not possible to deselect an item and hide/remove this window via the menu.

Moreover, even if the Find Results window is not selected, it does show up every time I use CTRL+F and hence does not honor my wish to not have it displayed.

Because every additional window requires some space I would prefer the possibility to decide myself if I want to have a Find Results window displayed or not.
