well i just need a little guidance here!
I have a form with multiple datacombo box on it.
depending if a user select an item from those combo I will do an sql query and find the information.
Do i have to test each combo if the user selected something and then generate the sql.  So it would look something like this
if combo1 not null then
sqlquery=select * where bla bla bla&
endif
if combo2 not null then
sqlquery=sqlquery & bla2 bla2 bla2&
endif
.
.
.


or is there a way to generate the full sql and regardless if info is selected or not it would do it withouth all those test.
Am new to vb programing am using Vb 6.
any guidance would help

You don't have the choice of using something similar to this:

sqlquery= "select * FROM table1 "
sqlwhere = ""
if combo1.text <> "" then
sqlwhere = sqlwhere & iif(len(sqlwhere)=0, " WHERE ", " AND ") & "Field1 = '" & combo1.text & "'"
endif

if combo2.text <> "" then
sqlwhere = sqlwhere & iif(len(sqlwhere)=0, " WHERE ", " AND ") & "Field1 = '" & combo2.text & "'"
endif

sqlquery = sqlquery & sqlwhere
