LabVIEW Idea Exchange

When running NI web server, the domain URL of the server will always redirect to the NI web server (or Systemlink) login page. Every Labview-built web application/webservice has a name and therefore must have a path (like: https://example.com/mywebapp)

I would like to be able to set a default redirect in the NI Web Server configuration to redirect the domain url to the default web application on that server.

It can probably be done in some Apache config file, but those a really managed by the NI web server configuration and are easily corrupted. My forum post about this issue has not yet been answered.

Idea:

So my idea is to add an optional parameter "ObjectRef" to both GObject methods "Replace" and "Replace No Attributes":

My request is mostly for replacing a control or a constant, but the proposed formalism could also work to replace any Node (SubVI, Structure, ...), a Diagram, a Panel, a Pane... by copying the properties and content of an existing one in memory.

Reasons:

Often in my scripting, I need to replace a control or a constant by copying an existing one. Most of the time, this is to change its data type, but also sometimes its style.

The current GObject methods "Replace" and "Replace No Attributes" are very handy to replace a control or a constant while maintaining their links to the other objects on the diagram, provided that you have the path to an existing (saved) .ctl file to give as a parameter to the method.

If the data type is not a type definition or is an unsaved type definition, things get complicated. This can happen and I don't have control over the data types passed to my tool.

To achieve this, I found 2 techniques:

1. Replace by a temporary Control file:

  - Create a new VI of type "Control VI";

  - Drop a new control using VI methods "Create from Data Type" or "Create from Reference";

  - Save the .ctl file to a temporary path;

  - Use method GObject.Replace with parameter "Path" on the old control / constant .

This works in most cases except when the data type contains out-of-scope typedefs. I can then work around this by disconnecting the typedefs and replacing sub-elements by path as a post-process, unless some typedefs are not saved by the user...

2. Recode the Replace method from scratch:

  - Drop a new control / constant using VI methods "Create from Data Type" or "Create from Reference";

  - Copy all relevant properties from the old control / constant to the new one;

  - Reconnected its terminal to the wire on the block diagram if needed;

  - For a control, relink locals, linked properties nodes, linked method nodes, references;

  - For a control, reassign it to the connector pane if needed...

  - ...

  - Delete the old control / constant.

This is a lot of work, seems quite inefficient and also is not future proof in case new properties are added to controls.

If different libraries are created by different manufacturers, the same error code can occur multiple times and each has a different meaning.

If you include a project code (unique UID) with the error code, for example, it is possible to provide a unique error message for different program code origins.

1) Bring to Error Constant a Tag for the Project

It would be really nice if you were able to resize properties dialog boxes for controls, indicators, constants, and other nodes on a front panel or block diagram. Sometimes the information entered in a dialog is larger than the allotted space. Fortunately, in those situations, there is usually a tip strip that shows all of the information rather than just the visible portion of the information, such as shown in the enum properties dialog box picture below. To make all information visible, it would be great if properties dialog box windows were resizable and the contents of the tab control pages automatically scaled with the size of the dialog. It would also be nice if pages containing objects with columns (e.g. multi-column listboxes, etc.) allowed the columns to be resized as depicted in the picture below. 

Open the VI Properties dialog when the Control key is depressed and the VI's icon in the upper right is double-clicked.

Right-clicking the icon shows a pop-up menu with VI Properties, Edit Icon..., and Find All Instances. Double clicking it opens the icon editor.

If I'm not mistaken, there currently isn't a single function that deletes a certain number of characters from a string. This can be done in a variety of ways using existing string functions, such as the example shown in the picture below. It would be really nice if LabVIEW contained a Delete From String function with offset and length inputs as illustrated in the same picture below. If you didn't wire up the length, maybe it could delete the remainder of the string and maybe an unwired offset could default to 0, similar to the String Subset function.

Bundle automatically names cluster elements for some references but not to a VI.
