LabWindows/CVI Idea Exchange

The CVI SavePanelState( ) and RecallPanelState( ) functions can be extremely useful.  Although the resulting panel state file is binary, it can however expose sensitive information with the use of even a simple tool like NotePad.  As a cumbersome workaround I had to use a command-line tool within my app, such as 7z, to compress and password protect the state file.   I suggest that CVI place a built-in protection into these functions.

I recently installed the LabWindows 2017 beta version on a lab PC and tried using it to run a project built with 2015 SP1.  Unfortunately it didn't work because of a bug I found in the beta: calling the NewBitmap or SetBitmapData function crashes the program if the number of bits per pixel is 1 or 4.

Uninstalling the beta is proving to be difficult.  I performed an uninstall on LabWindows 2017 and Run-Time Engine 2017 through the Windows control panel, but it made me uninstall LabWindows 2015 SP1, NI-DAQ, and LabVIEW as well (because they were all dependent on the RTE).  Windows appeared to run the uninstall successfully, but the RTE folder and DLLs were somehow not removed or changed.  So when I rebuilt and re-ran my project, it still linked with the 2017 RTE and still crashed.  I had to manually copy the 2015 RTE files from another PC.

Even after this, there are still some other elements of the 2017 version left on the PC, such as the activation manager.

I would like to NI change this so that when the user uninstalls a new RTE, it automatically restores whatever previous version was active before the update without the hassle of having to uninstall and reinstall LabWindows, LabVIEW, etc.

Based on this discussion, Strip Chart controls don't support cursors.

I think it would be great if this support would be added.

The best option would be to have an advanced cursor like the "Graph Cursors Control" available for Graphs.

Other text editors such as UltraEdit have the capability to trim white space from the end of lines.  This would be a useful feature, as sometimes extra white space can end up at the end of lines, and is annoying when copy/pasting, etc.  I would expect to find it under Options->Editor Preferences, similar to the tab/space settings.

To export enum types with a dll there is a fine menu "Generate Function Tree...". Using the Help Buttom, one finds is a description on how to use it. It is mentiond not to nest the different comment type. "Avoid nested comments or combinations of comment styles ...... (backslashes, stars, etc.), what I understand. - Unluckily, if one uses comma "," or semicolon ";" within a comment, the tool fails with "I n v a l i d enum typedef.", what I consider is a bug. This makes the tool less valuable, especially if one resuses C source code from thirdparties.
