Common tips for labview and tips for labview

1. the right side of the front panel is a combination or cancel combination button. Multiple controls can be combined together, and different controls can form the habit of forming a cluster.

2. View-> tool palette. The bottom is the color palette. You can modify the control style.

3. Each time you design a front panel, you need to customize the size. In the file-vi attribute, you can set the front panel size, runtime location, style, and so on.

4. When you do not know the type of input, right-click to create a constant for reference.

5. Help and examples are useful!

6. To call sub-vi on the front panel, first create a container control and then display and run the function. Two conditions are required for removing the scroll bar in the container:

A. subvi should design the scroll bar style (Custom button) in the vi attribute );

B. You must run this function.

7. When you need to bring up a simple dialog box, you can directly call the function encapsulated by the application.

8. Boolean-to-number conversion is very useful, especially when combined with the creation of array functions, it is very easy to implement the Judgment part similar to the 3-8 decoder.

9. if the button is triggered at a level, use if. If edge is triggered, use the event structure (value change ).

10. Within a main thread, the while structure must be placed outside the event structure, and will be waiting. If you do not want to cause a crash wait, the following solutions are available:

A. Set a timeout event. For example, if 50 is set, if the event structure is not triggered within 50 ms, the program in the timeout event will be executed;

B. (recommended) a while statement is a thread. If event structure intervention is required, you can place other service programs in another while loop. The event structure is a separate loop, implement multi-threaded effect (parallel ).

11. If network programming is involved, ensure that the firewall of windows is disabled and ping the firewall. You can use localhost for local testing.
