Microsoft Access - Does a value exist for this record? -


forewarning - new microsoft access , have limited knowledge of formulas , expressions. go easy!

i've built basic database store , track stories of people nonprofit organization has helped (we're calling them "subjects"). produce various publications , it's important know when , we've featured our subjects, can avoid repeating same content in same publication.

when putting content new issue, ask ourselves "okay, haven't featured in publication before?"

this i'm trying accomplish right now: able , find out hasn't been used in particular publication.

here tables , relationships.

enter image description here

a subject's content used in number of publications ("use/type publication")

so basically, trying say: if specific value in "use/type publication" field exists "subject(s)" , don't show subject in results

or alternatively, results subjects , return value yes/no.

i want able input specific value.

for example, "show me of subjects have never been used in our spirit enewsletter."

i hope enough information. appreciate can get!

design query; when put these 2 tables query design view - join line display assuming you've made permanent join in relationships. if not make join line displaying.

then put cursor on line itself, right click, , alter join type of contentversion selected. join line have arrow pointing @ content table.

add fields query of both tables.

run query , you'll of contentversion data , there no match you'll see nulls/blanks in content. here can continue customize meet needs.

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
