sql - Searching a table to find a certain ID: error 80040e10 no value for one or more parameters -

-

in access 2007, searching table find id. id address given in text box user idtxt.
error 80040e10 no value 1 or more parameters.

private sub search_click()   'here new part i'm not sure about... dim cn adodb.connection dim rsq adodb.recordset  set cn = currentproject.connection set rsq = new adodb.recordset  dim strsql string  dim id_number integer dim blnexists boolean blnexists = false id_number = idtxt.value  strsql = "select * table1  id = id_number;" rsq.open strsql, cn, adopenstatic  if rsq.recordcount <> 0      ' found     blnexists = true     msgbox "found" else     msgbox "not found" end if  end sub

your passing string without substituting value;

strsql = "select * table1  id = id_number;"

needs 

strsql = "select * table1  id = " & id_number

as id_number in context of vba variable outside string.

(your not performing type checking on id_number text in unrestricted textbox error, , string parameters injection vulnerability)

also note recordcount can return -1 depending on cursor location/type.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
