Plus Code

i have following code: intbuffer drawbuffers = utils.createintbuffer(2); int bfs[] = {gl30.gl_color_attachment0, gl30.gl_color_attachment1}; for(int = 0; < 2; i++) drawbuffers.put(bfs[i]); drawbuffers.flip(); gl20.gldrawbuffers(drawbuffers); if flip intbuffer int status = gl30.glcheckframebufferstatus(gl30.gl_framebuffer); don't equal gl_framebuffer_complete , if don't flip status right, black texture instead of desired texture, looked throught code on , on 2 days now, best bet part of code somehow wrong, rest seems ok. should intbuffer flipped before using in gldrawbuffers(intbuffer) ? yes, buffers should flipped before being passed lwjgl. the underlying gl api expects array functions take java buffer. size of array parameter in gl's c language bindings, hidden in java because lwjgl calculates difference between current position , end position. unless flip java.nio.buffer , sets "current" position beginning of buffer,...

let's have 3 sheets (let's sheet1 , sheet2 , sheet3 ). sheet1 , sheet2 contain each sheet-level range named myrange . in sheet3 , if want access myrange sheet1 , able use ='sheet1'!myrange . but now, want sheet3 contain generic code , able refer either sheet1 or sheet2 . expect able achieve same thing using =indirect("'" & mysheetname & "'!myrange") however, error #ref when that. what do wrong ? how can work around ? if myrange consists of multi-row, multi-column range, make sure pressed ctrl-shift-enter when entered =indirect("'" & mysheetname & "'!myrange") . if forget use ctrl-shift-enter , #value error. however, stated have #ref . using code single-cell range, result looking for. way can #ref error using wrong sheet name. suspect problem. check sheet name , repost more detail if still doesn't work.

is possible "constrain" columns in 1 table "reference" columns views in information_schema in way (it needn't proper foreign key constraint, hence scare quotes)?-- need minimally-intrusive way of adding arbitrary metadata existing column data (e.g. add "comments" e.g. value shop.cheeses.name shop.cheeses.id = n ), , thought of defining table such: create table shop.metadata ( `table_schema` varchar(64) not null, `table_name` varchar(64) not null, `column_name` varchar(64) not null, `record_id` int(11) unsigned not null, `comments` text not null, /* show purpose of table */ primary key (`table_schema`, `table_name`, `column_name`, `record_id`), foreign key (`table_schema`, `table_name`, `column_name`) references information_schema.tables(`table_schema`, `table_name`, `column_name`) ); however, statement returns error 1215 (hy000): cannot add foreign key constraint , presumably because table_schema , table_name , co...
