c# - Get Item[i] from listview -

-

i trying item[i] string listview. don't seem understand supposed do, when listview on thread. 

public delegate void getcurrentitemcallback (int location); ... private void runasthread() {    while (..>i)    {     //i tried following //doesn't work.     //string item_path = listview.item[i].tostring();         //attempting thread safe. how return string?     string item_path = getcurrentitem(i);    } } private void getcurrentitem(int location) {    if (this.listviewmodels.invokerequired)       {        getcurrentitemcallback d = new getcurrentitemcallback(getcurrentitem);        this.invoke(d, new object[] { location });       }       else       {        this.listviewmodels.items[location].tostring();       } }

what missing?

you need have delegate type returns string, not void, begin with.

then, need matching method return string well.

public delegate string getcurrentitemcallback (int location);  ...  private string getcurrentitem(int location) {    if (this.listviewmodels.invokerequired)       {        getcurrentitemcallback d = new getcurrentitemcallback(getcurrentitem);        return this.invoke(d, new object[] { location });       }       else       {        return this.listviewmodels.items[location].tostring();       } }

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.
