Creating an XPath Expression in SharePoint's "Add Formula Column" based on meta data -

-

ok,

so first post stack overflow, , did search , couldn't find looking regard question (although might terrible @ searching). essentially, first pass @ xpath expressions , having tough time creating if/else statement.

i have dwvp displaying list of documents document library on separate site. have column notes whom document checked-out (if checked-out), , if document checked out, have conditional formatting highlight row.

all far. have list of documents have bunch of meta data , 1 or 2 of rows in list highlighted yellow because checked-out, , users name listed in "@checkedouttouser" column.

my issue want create column (i'm assuming formula column) within dvwp display link source document library (specifically view enabled filters content "checked out to" [me], that's no issue) if column "@checkedouttouser" has in it.

my thought process here new formula column check see if anything written (or alternatively not written) in column, , if create link says "check-in document". if @ dvwp, see yellow row indicates document has been checked out, , since yellow , since checked out, right-hand formula column show link says "check-in document".

i have never written xpath expression before, got somewhere following expression:

if /@checkedouttouser!=" ",

i have feeling start that?

what expression like?!

not quite sure want do, little bit of xslt , xml help

<xsl:if test="@checkedouttouser"><span>add content<span></xsl:if>

if need display underlying xml page, deprecated tag

<xmp><xsl:copy-of select="." /></xmp>

will trick.

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.
