c# - iTextSharp Paragraph Containing a Table not Written to a Column -

-

in following code, creating pdfptable, adding paragraph. try add paragraph column. doesn't work. never gets added.

if add table directly column, added fine.

what doing wrong?

(fwiw, simplified version of larger project has elements created in manner.)

here code:

    private void form3_load(object sender, eventargs e)     {         string pdffile = string.format("{0}{1}.pdf", path.gettemppath(), guid.newguid());         document pdfdoc = new document();         pdfwriter writer = pdfwriter.getinstance(pdfdoc, new filestream(pdffile, filemode.create));          pdfdoc.open();          pdfcontentbyte pcb = writer.directcontent;          columntext columns = new columntext(pcb);          pdfptable table = createtable();         paragraph para = new paragraph();         para.add(table);         columns.addelement(para);         columns.setsimplecolumn(0, 0, 72*8, 72*11);         columns.go();         pdfdoc.close();         process.start(pdffile);      }      private pdfptable createtable()     {         pdfptable table = new pdfptable(2);         table.addcell("bob");         table.addcell("mike");         return table;     }

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
