asp.net - Display an image in an Image control using FileUpload -

-

i want show image in image control user select image file through fileupload control, don't want image saved on server.

the best have uploaded memory, , without saving display using .ashx or something.

edit

before html5, perhaps have done having javascript function takes directory of uploaded file , sets img src property filepath. image load preview own hard drive. in html5 compliant browsers, filepath hidden can't use in javascript. happens in ie8, chrome, etc.

here's messy way it.

first, create javascript function handle fileupload controls onchange event. when event fires, post entire form.

        function uploadfile() {         var value = $("#<%=futest.clientid %>").val();         if (value != '') {             $("#form1").submit();         }     }

here upload control:

    <asp:fileupload runat="server" id="futest" onchange="uploadfile()" />

now, when chooses file, form posts , can take image memory on server , display when postback complete.

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.
