objective c - NSColor | Creating Color from RGB Values -

-

in application, rgb values unsigned character not more 255, using nscolor api create color , make use of draw font , background color,

this function have written 

+(nscolor *)getcolorfromrgb:(unsigned char)r blue:(unsigned char)b green:(unsigned char)g {     cgfloat rfloat = r/255.0;     cgfloat gfloat = g/255.0;     cgfloat bfloat = b/255.0;      //  return [nscolor colorwithcalibratedred:((float)r/255.0) green:((float)g/255.0) blue:((float)b/255.0) alpha:1.0];     return [nscolor colorwithcalibratedred:rfloat green:gfloat blue:bfloat alpha:1.0]; }

in case, when compare color using rgb value in rgb palate, color not matching, example, when pass ,

r = 187, g = 170, b = 170,

it should draw light gray, getting complete whilte color, in case,

anyone has idea, doing wrong,

kind regards

rohan

if passing input components out of 255 , want restrict within 255 safety purpose, can try this:

cgfloat rfloat = r % 255.0; cgfloat gfloat = g % 255.0; cgfloat bfloat = b % 255.0;

instead of divide use % value.

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

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.
