View 6 RepliesMy question is how best to avoid SQL Injection with the method I am currently using.EDIT (Reasoning): There are many of columns in a number of tables (a number which grows (only) and is maintained elsewhere). I need a method of allowing the user to decide which (predefined) column they want to query (and if necessary apply string functions to). The query itself is far too complex for the user to write themselves, nor do they have access to the db. There are 1000's of users with varying requirements and I need to remain as flexible as possible - I shouldn't have to revisit the code unless the main query needs to change - Also, there is no way of knowing what conditions the user will need to use

Ho can you make a dynamic label stay right justified, so that when the label.text is filled the text starts at the right edge of the label and fills to the left? Currently the text fills to the right from the left edge of the labels location and tends to run off the form.
