How to disable Keyboard and mouse input

[jacky Wang]

  My application background is I don't want operator to input serial number by keyboard, because we are using barcode scanner during the PreUUT of Teststand. It's a function like error proofing, avoiding the inproper operation of operator.
  In order to disable keyboard and mouse input, I can use LabVIEW Event structure function to filter mouse/click event, but that's not suitable, also I try to find a windows API function, but seems to complicated (Hook function). So I raise this question and hope somebody could help me on this. CVI or Teststand ActiveX methods are prefered.
  Attached picture could better make clear my questions

Thanks

Hi Jacky,

I dont believe there is anything in TestStand API that will disable the keyboard but you could substitue the IdentifyUUT function for one of your own to obtain the serial number from the barcode reader. How do you intend for the operator to exit out of the UUT loop?

    Attached is what I would like to see, in PreUUT: 1, disable keyboard and mouse input; 2, Identify UUT step; 3, enable keyboard and mouse input.

Hi, Ray

How i can to tell to 'IdentifyUUT' to get the number automatically (not pop-up/dialogue), because i do not want to get 'pop-up' dialogue..?

Here, I'm glad to post a solution, please see attached seq file. To be noted, I have inserted some steps in the PreUUT sequence call. When running tes UUT,  keyboard and mouse action will be disabled, except the key:Ctrl+Alt+Del

Thanks!

Does exist in general oportunity to set IdentifyUUT to get data automatically without user interaction?
