c# - How to set default values for the properties of a derived control? -

i derived toolstripcombobox in order create 1 encapsulates percentage picking dropdown. goal have of validation , string parsing in derived control. parent receives event when percentage chosen has changed, , can access public integer getting , setting percentage.

the problem have in designer file parent command place derived command on, keeps adding total set of strings using combobox.items.addrange method. in constructor derived command have following:

foreach (int in percentages) { combobox.items.add(string.format("{0}%", i)); }

over time these values accumulate in designer file many, many times over. don't know how create items property hidden since it's not virtual. want suppress flooding of designer file.

example of designer file:

this.zoom_cbo.items.addrange(new object[] { "10%", "25%", "50%", "75%", "100%", "150%", "200%", "300%", "400%", "600%", "800%", "1600%", "10%", "25%", "50%", "75%", "100%", "150%", "200%", "300%", "400%", "600%", "800%", "1600%", "10%", "25%", "50%", "75%", "100%", "150%", "200%", "300%", "400%", "600%", "800%", "1600%", "10%", "25%", "50%", "75%", "100%", "150%", "200%", "300%", "400%", "600%", "800%", "1600%", "10%", "25%", "50%", "75%", "100%", "150%", "200%", "300%", "400%", "600%", "800%", "1600%", "10%", "25%", "50%", "75%", "100%", "150%", "200%", "300%", "400%", "600%", "800%", "1600%", "10%", "25%", "50%", "75%", "100%", "150%", "200%", "300%", "400%", "600%", "800%", "1600%"});

since it's derived list user selecting from, seek adding derived combo box prevent serialization of items:

[browsable(false)] [designerserializationvisibility(designerserializationvisibility.hidden)] public new objectcollection items { { homecoming ((combobox)this).items; } }

c# winforms inheritance control default-value

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
