device index of a joystick depends on what exactly

[achfire]

i don't understant the id depends on what, is it The sys of exploitation used( windows 7 , 8 , xp) or the port used or the computer.

when i use a joystick with windows 7 the id is 0

when i use it with windows 8 i got 5 ,but when i restart the computer it become 3 using the same port

when i use it with windows xp i got 3 with one computer and 0 with an other one.

so

achfire,

The joystick device name should be the same on every computer.

To get the ID from the device name, search through all detected joysticks until the device name matches.

Here is a screenshot of how to do this:

This VI is not included with LabVIEW, so you'll have to code it yourself.

i did it,but i get false ,i don't know why even if i see that names are the same

What is the device name of your joystick?  Have you tried using hilight execution mode to debug your program? Alternatively, you could check the number of buttons and axes matches instead of the device name.

yes i used hilight execution mode to debug my program,but i noticed that the name is the same but i get F ,i'll try ur suggestion

Are you abosultely sure your strings are indentical?  Your code looks like it should work.

I would temporarily add an indicator between the "Query Input Devices.vi" and your for loop, run the VI once, then copy and paste whatever your device name is from the array indicator to the "Joystick Name" string control just to be sure.  (Then you can get rid of the indicator.)
