Greeting,

I am trying to select features using attribute query. Variable are referenced to listbox. Can anyone please let me why my whereclause is set to false and i am unable to select the features.
please ref the attached screenshot.

pqf.WhereClause = fieldname = fieldvalue : is the expression i used to implement fieldname and fieldvalue as variables.Tried various options like using &, ", ( etc etc...but did not find a way to use both as variables(fieldname and fieldvalue).

thanks n regards,
shiva

The WhereClause property expects a string, therefore you must set it using a string expression.

queryFilter.WhereClause = fieldName & " = '" & stringValue & "'"

If the field isn't a text field then you must remove the single quotes.
