vb.net - .NET exception not appearing for some user accounts -

i'm facing error in vb.net application shows next information:

system.argumentnullexception: 'name' argument cannot null. parameter name: name @ system.data.datacolumncollection.get_item(string name) @ system.data.datarow.getdatacolumn(string columnname) @ system.data.datarow.get_item(string columnname) @ siwapro.utilities.getlabel(string frmname, string ctrlname) @ siwapro.frmhaupt.beschriften(control ctrl) @ siwapro.frmhaupt.frmhaupt_load(object sender, eventargs e) @ system.windows.forms.form.onload(eventargs e) @ system.windows.forms.form.oncreatecontrol() @ system.windows.forms.control.createcontrol(boolean fignorevisible) @ system.windows.forms.control.createcontrol() @ system.windows.forms.control.wmshowwindow(message& m) @ system.windows.forms.control.wndproc(message& m) @ system.windows.forms.scrollablecontrol.wndproc(message& m) @ system.windows.forms.containercontrol.wndproc(message& m) @ system.windows.forms.form.wmshowwindow(message& m) @ system.windows.forms.form.wndproc(message& m) @ system.windows.forms.control.controlnativewindow.onmessage(message& m) @ system.windows.forms.control.controlnativewindow.wndproc(message& m) @ system.windows.forms.nativewindow.callback(intptr hwnd, int32 msg, intptr wparam, intptr lparam)

the error comes when i'm logged in administrator, not when utilize software "normal" user.

what can reason of this? there .net runtime parameters depend on current user account?

.net vb.net exception user-accounts administrator

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...
