sql server - Error assigning pass through query to report recordsource in VBA code -

-

i have following code :

    private sub report_open(cancel integer)       on error goto errorhandler         dim isptqueryexists integer     isptqueryexists = isquery("mytestquery")     if isptqueryexists = -1     set qdf = currentdb.querydefs("mytestquery")     qdf.sql ="my sql query"      me.recordsource = "mytestquery"     end if     else     dim databasename string     dim servername string     servername = "xxxx"     databasename = "xxxx"     set qdf = currentdb.createquerydef("mytestquery")     strconnectionstring = "xxxx"      qdf.connect = strconnectionstring    qdf.sql = "my sql query"    me.recordsource = "mytestquery" end if errorhandler:  msgbox err.description end sub  ********************************************************       ' function: istablequery()       '       ' purpose: determine if table or query exists.       '       ' arguments:       '   dbname: name of database. if database name       '           "" current database used.       '    tname: name of table or query.       '       ' returns: true (it exists) or false (it not exist).       '       '********************************************************       function isquery(qname string) integer       dim found integer       dim queryname string       const name_not_in_collection = 3265          ' assume table or query not exist.          found = false          ' trap errors.          on error resume next          ' see if name in queries collection.          queryname = currentdb.querydefs(qname$).name          if err <> name_not_in_collection found = true          isquery = found       end function

i have report . i trying set record source of query dynamically vba code pass through query .

i dont have query def created @ design time , not specifying record source report , design time

in code , checking if query def exists , if , changing sql property of , setting record source .

if query def not available , creating new 1 setting record source.

the problem here : whenever execute code , showing error:

"item not found in collection" . if click on ok button of message box continues run , displays report .

but , not sure why error occuring ,and why code not failing error ?

any thoughts on this? . have put lot of efforts tounderstand in vain

updated :

if dont use error handler , not throwing exception

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
