I have an application where I need to get many responses from the user by way of two button dialogs. I need to sense the state change of a latched DI and when it goes HIGH, display a two button dialog box for the user to interact. Since this happens inside a 100ms while loop, I need to supress the dialog box after user choice is made. Otherwise the pop up will happen repeatedly as the DI is latched in HIGH state. While I have been able to get the functionality with a shift register ( refer attachment in LV2009), I was wondering if there was a better way to do these kind of "once-only-messages" ? Thanks

It is not a good idea to change the state of the Digital Input which is "Read Only" The final VI with the required modification is as below :

LabVIEW

Solved!

thanks a lot

If you want different results, use button not use switch.
