I need a little help here, maybe I'm making this complicated but essentially I want to display a tattooed WMI entry if it exists, if it doesn't exist, then a string of text that I've defined. Otherwise, maybe PowerShell is the way to go?
The goal here is so that IT support can easily determine the device being SCCM built or AutoPilot
WMI=set:OSTSName,namespace:root\MYCOMPANY,query:MWP_OSD,display:%TaskSequenceName%,hidden:1
IF=value1:%OSTSName%,value2:null,comparator:eq
set OSTSName2=AutoPilot
TEXT=text:Build Type,display:{{{%OSTSName%}}}{{{%OSTSName2%}}},font-size:100%,color:ffffff
I don't think null is a valid value in DTI. It usually replaces a null return with a text value to avoid crashing. The null-result value under the [text] section can define what that should be. Then you'd just need something as simple as the following. You may need value2 to be blank, or matched up to the null-result value.
WMI=set:OSTSName,namespace:root\MYCOMPANY,query:MWP_OSD,display:%TaskSequenceName%,hidden:1 IF=value1:%OSTSName%,value2:,comparator:eq,true:AutoPilot,false:%OSTName%,set:BuildType=%1 TEXT=text:Build Type,display:%BuildType%,font-size:100%,color:ffffff
Also, just reviewing this, it should be "comp", not "comparator".
if the wmi query truly returns a null then DTI will replace it with whatever is in the [text] section as Nathan has advised so that it's got something to put on the screen. Then the IF command would want to compare with that. The default is <null>
I don't have the code handy to check but I suspect both comparator and comp are ok. I notice both appear in the manual. It might have originally been comparator but I got sick of typing that so I added the abbreviated version as well. I've done that in a few places.
also check the IF command in the manual for a more compact way of achieving your goal.
