vba - Unable to add record. Joinkey of table not in recordset?MS Acess 2007 -


i have been trying have form can enter patient details along medicines prescribed. have created 5 tables this.

  • tblpatients patient details patient id primary.
  • tblvisit visit details visitdt,tests,etc, visit_id primary.
  • tblmedicines list of medicines(which can add dynamically).
  • tblqnty specific doses , qnty mentioned during specific visit.

i have created form patient , visit info , subform inside form medicines , qnty(in tabular form).

now facing 2 issues:

  1. i unable set subform blank default on load mainform new record. have tried on subform not working.

  2. while trying add record in subform receive error message "unable add record. joinkey of table tbkqnty not in recordset?"

database relationship data entry form , subform

1) if 'blank' mean 'empty': @ point 2)

2) in recordset of subform must have field visit_id. if don't want show in subform set visible: no

3) link 2 forms (main- , sub-) visit_id (table tblvisit) link master field , visit_id (table tblmedicines) link child field in main form 'data' property sheet tab.

4) in subform, in before_update event set 

sub form_beforeupdate(cancel integer)     visit_id = me.parent!visit_id  end sub

(supposed control names equal field names).

this ensure records in child table tblmedicines related 1 record in table tblvisit.

hope helps.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
