How can text scrolling be implemented in LabVIEW?

There are two methods to achieve scrolling text display in LabVIEW: using a String Indicator and using a String Control.

Option 1: Method one involves utilizing a String Indicator.

1. Drag and drop a String Indicator control onto the Front Panel.
2. Right-click on the String Indicator control, select Create » Property Node » Visible Items.
3. Drag and drop the Visible Items property node onto the Block Diagram.
4. Connect the Visible Items property node to a While Loop structure to continuously update the displayed text.
5. Utilize string manipulation functions (such as String Subset) within a While Loop to update the value of the Visible Items property node.
6. Use the Delay function to control the scrolling speed.

Option 2: Utilize String Control.

1. Drag and drop a String Control onto the Front Panel.
2. In a Block Diagram, Shift Registers are used to store the rolling position.
3. Update the value of String Control in the While Loop using string manipulation functions like String Subset.
4. Control the scrolling speed by using the Delay function.
5. Include an Event Structure so that user input can be received and processed during the scrolling process.

Both methods can achieve scrolling text display, the specific choice depends on your needs and the actual situation.
