async/await does not handle errors. It just lets your program to do stuff in the background, allowing the main program to keep going. It's probably not even necessary here since writing to a file should not take much time. If you want to handle errors, you need use exception handling. try ( Fi ...

We've been using this method for a few years now - except we write JSON files, not XML, but the principal is the same. We write to these files as often as once every 10 seconds (occasionally faster) and collisions with Datalinq reading the file as we are writing them are rare. In the event of a collision, ...

RE: Scene Object Deleted when calling Scene.Project.FontExistsByName from external API

There doesn't seem to be anything wrong with the code. The problem lies elsewhere. Possibly the project is reloaded or the scene was deleted invalidating your Scene object. FWIW, this snippet works fine for me (Xpression Developer v10.0). private void button2_Click(object sender, EventArgs e) ...

Since the type of the array is Object, you need to cast to double before calling ToString. Change those 2 lines to: percent.Text = CDbl(data(i - 1)(1)).ToString("N1") & "%" percentch.Text = CDbl(data(i - 1)(2)).ToString("N1") & "%"​ ​ ------------------------------ JohnCorigliano Senior ...

Things get trickier when sorting data with multiple fields. I would put the data in an array of 3 items. Then put those arrays into a List. You will need to create a custom sorter function. Since Xpression doesn't seem to support Linq or lambda expressions, put this in your global script: Function ...

Read Folder List in Dashboard

Is it possible to have Dashboard read a list of files from a folder? For example, we give the clients a folder then can add their homemade graphics to and then let them choose a graphic to put on air (Xpression) from Dashboard. We currently have a work around using custom software that watches a folder ...

I'm a little confused right now about what you are trying to do, but here's what I think you want... The biggest question is about the data source. I think it is a JSON file. As far as I know you can't sort JSON data through the DataLinq Server (anyone?). So you will need to create 15 hidden text ...

In the first message you said scripting but now you are asking about Visual Logic. Which is it? What is the data source? Maybe you can sort it in the DataLinq Server if using SQL. Also, for the debug monitor, check that it is enabled in the Preferences under Advanced-Enable debug monitor for scripting. ...

Looks like it is sorting alphabetically instead of numerically. You can convert the strings to numbers before sorting. Also, as you have figured out, if your culture uses ',' instead of '.' for decimals you have to either replace the '.' with ',' or use a different culture. Demo: ' Create test array ...

It says "Each data transmission should be terminated with a NULL character." Make sure your API is adding this, else Datalinq Server won't process the data. ------------------------------ JohnCorigliano Senior Software Engineer ISC ------------------------------

Another possible work-around is to create a single, hidden text object with DataLinq enabled. Then create as many copies of that as needed, modifying the Datalinq fields as needed.

Yes, you can use an ODBC driver, but the nice thing about Sqlite is that it is file based. With a Sqlite aware app, nothing else needs to be installed - no drivers or ODBC, etc. This helps simplify deployment and avoids 32/64 bit driver issues. ------------------------------ JOHN -------------- ...
