How To Change Tv Connection To Auto Detect

[Sherry Galeazzi]

Imay have figured out the issue, based on a difference in how Windows 10 handles VPN configuration through the new menu. In the Advanced Settings for a VPN connection in the VPN Settings (specifically the Windows 10 menu, I have yet to see this elsewhere), there is a Proxy settings drop-down menu that allows for configuration per adapter. I happened to check that page and noticed that it was set to Automatically detect settings for one of the users who was having issues. We will need to test to make sure this is a persistent setting and that changing this and applying actually prevents the checkbox from re-enabling proxy settings upon subsequent connections, but it looks hopeful.

To my knowledge, that makes it impossible to easily* recognise them in Labview if you haven't renamed them in NI max beforehand.... which, in my experience has caused issues (for some reasons, a motor controller connected via USB had the same COM port (and so alias I created) than an adapter... that was a mess)

My idea was, either by use of a keyboard shortcut, or constantly in the background to call this VI which uses the Find VISA ressources in loop, and checks if the table created between two iterations have changed or not.

The thing is, because Find VISA ressources.vi is auto-sorting the ressources found (if the devices ASRL11 is connected after ASRL12, it will still appear before in the table), a simple "Not Equal" differenciation would not work, so I came up with this double FOR loop checking every elements of both arrays (the new array and the previous one) between each others. And the VI stops as soon as one element in the new was not found in the old.

I've been thinking about making something like this, because currently the device i'm working with uses 3 USB connections and port for each has to be manually checked in device manager and then written to config file. Luckily windows remembers the configuration so this only has to be done once (unless you switch sensors or machines).

I have had to do something similar and here is the VI I made to do the detection. This basically replaces the code inside of your loop as I used "Filtered Ports" as the list of ports that were found before I did something (in my exact case, turn on a UUT that then showed up as a COM port). I also had to make sure it was a COM port because I had issues with the parallel port also showing up. This does require that nobody change alias names in MAX as I depend on the default alias names for serial ports (COM%d).

For some reason I can't find such Search 1D array ... I was sure it would exist, but even after double checking, I still can't find it... but only the "Search 1D sorted Array.vim" which didn't worked as it requires a class as input ?!?

And as I was exploring the aliases in the past, some devices are now named, and some others not. For some reason there is a difference in labview between COM ports and Canonical names: Devices can have the same COM port, but not the same Canonical name (in my experience, but I could've made some mistakes.)

Agreed, but then it is very specific to each and everyone cases I just wanted something that I could re-use in all my programs, that gives me a Ressource name that I can directly link to Open VISA

If the device doesn't communicate properly, then it means that I've either connected the wrong one (not that it never happened , this made me go crazy a few times...); the device is broken; or the drivers are not installed on the computer. At least in my case

But again, I've tried to connect my array of string to the vim one, and I had a broken wire. It's only by opening it and manually changing the inputs that it worked out... I quite don't get how .vim work yet

If you query two or more tables at the same time, when the data is loaded, Power BI Desktop attempts to find and create relationships for you. The relationship options Cardinality, Cross filter direction, and Make this relationship active are automatically set. Power BI Desktop looks at column names in the tables you're querying to determine if there are any potential relationships. If there are, those relationships are created automatically. If Power BI Desktop can't determine with a high level of confidence there's a match, it doesn't create the relationship. However, you can still use the Manage relationships dialog box to manually create or edit relationships.

By default, Power BI Desktop automatically configures the options Cardinality (direction), Cross filter direction, and Make this relationship active for your new relationship. However, you can change these settings if necessary. For more information, see Understanding additional options.

If none of the tables selected for the relationship has unique values, you'll see the following error: One of the columns must have unique values. At least one table in a relationship must have a distinct, unique list of key values, which is a common requirement for all relational database technologies.

The first method to edit a relationship is using the Editing relationships in the Properties pane in Model view, where you can select any line between two tables to see the relationship options in the Properties pane. Be sure to expand the Properties pane to see the relationship options.

The other method of editing a relationship is using the Relationship editor dialog, which you can open many ways from within Power BI Desktop. The following list shows different ways you can open the Relationship editor dialog:

Finally, you can also edit a relationship from any view, right-click or select the ellipsis to get to the context menu of any table, then select Manage relationships, select the relationship and then select Edit

Using the Edit relationships dialog is a more guided experience for editing relationships in Power BI, and is currently in preview. You can see a preview of the data in each table. As you select different columns, the window automatically validates the relationship and offers appropriate cardinality and cross filter selections.

Editing relationships in the Properties pane is a streamlined approach to editing relationships in Power BI. You only see the table names and columns from which you can choose, you aren't presented with a data preview, and the relationship choices you make are only validated when you select Apply changes. Using the Properties pane and its streamlined approach reduces the number of queries generated when editing a relationship, which might be important for big data scenarios, especially when using DirectQuery connections. Relationships created using the Properties pane can also be more advanced than the relationships allowed to be created in the Edit relationships dialog.

You can also multi-select relationships in the Model view diagram layouts by pressing the Ctrl key and selecting more than one line to choose multiple relationships. Common properties can be edited in the Properties pane and Apply changes will process the changes in one transaction.

Editing relationships in the properties pane feature is currently in preview. While in preview, functionality and documentation are likely to change. You must enable this feature in Power BI Desktop by going to File > Options and settings > Options > Preview features and then in the GLOBAL section, select the checkbox next to Relationship pane.

When you create or edit a relationship, you can configure more options. By default, Power BI Desktop automatically configures more options based on its best guess, which can be different for each relationship based on the data in the columns.

Many to one (*:1): A many-to-one relationship is the most common, default type of relationship. It means the column in a given table can have more than one instance of a value, and the other related table, often know as the lookup table, has only one instance of a value.

One to one (1:1): In a one-to-one relationship, the column in one table has only one instance of a particular value, and the other related table has only one instance of a particular value.

One to many (1:*): In a one-to-many relationship, the column in one table has only one instance of a particular value, and the other related table can have more than one instance of a value.

Many to many (*:*): With composite models, you can establish a many-to-many relationship between tables, which removes requirements for unique values in tables. It also removes previous workarounds, such as introducing new tables only to establish relationships. For more information, see Relationships with a many-many cardinality.

Both: For filtering purposes, both tables are treated as if they're a single table. The Both setting works well with a single table that has many lookup tables that surround it. An example is a sales actuals table with a lookup table for its department. This configuration is often called a star schema configuration (a central table with several lookup tables). However, if you have two or more tables that also have lookup tables (with some in common) then you wouldn't want to use the Both setting. To continue the previous example, in this case, you also have a budget sales table that records target budget for each department. And, the department table is connected to both the sales and the budget table. Avoid the Both setting for this kind of configuration.
