Multi level inheritance in vb.net -

i want implement multi level inheritance in vb.net application. have base of operations form named base_level0 contains methods, properties etc. 1 more form named base_level1 inherits base_level0.

these 2 forms base of operations forms.

now actual form named form1 inherits base_level1. form1 contains form load event not fired.

but if form1 inherits base_level0 straight load event fired. why load event dose not fire multi level inheritance.

these 3 lists usercontrols.

***base list level0 public class frmnewbaselist_level0 ' ' private sub frmnewbaselist_level0_load(sender object, e system.eventargs) handles me.load end sub ' ' end class ***base list level1 public class frmnewbaselist_level1 inherits frmnewbaselist_level0 ' ' private sub frmnewbaselist_level1_load(sender object, e system.eventargs) handles me.load end sub ' ' end class ***actual list public class frmcustomerslist inherits frmnewbaselist_level1 ' ' private sub frmcustomerslist_load(sender object, e system.eventargs) handles me.load end sub ' ' end class code add together these list main form given below: public sub setmdichild(byval smdichild usercontrol, byval smdiparent form) smdichild.parent = smdiparent smdichild.dock = dockstyle.fill smdichild.show() smdichild.bringtofront() enablesearch = true end sub

frmcustomerslist phone call in mdi form below:

if (ofrmcustomer nothing) ofrmcustomer = new frmcustomerslist end if setmdichild(ofrmcustomer, me)

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...
