if u want to send an sql statement

for example
select * from table where table.field = value

Use this

crystalReport1.SelectionFormula = "{table.field} = '" & value & "'"


If u want to sent a string to the report formula

USe this

CrystalReport1.formulas(0) = "formulaname = '" & valve & "'"


Is this the solution that u want ?

If else eloborate your question.
