How to fetch pretty advanced relation in Drupal 6 - Views 2? -

-

i have 3 content types: artist, artwork, exhibition. exhibition has field 'artworks' (unlimited values). artwork has field 'artist' (1 value, required).

and there relation can't seem find views: want exhibitions artist ever participated in. means: on artist page, show exhibitions artworks of artist ever in.

the problem (i think) 1 field (exhibition.artworks) has many values. yet artwork.artist has 1 value.

i don't know problem =) it's not working , i've tried million things. @ point, i'll accept writing sql queries, drupal content database incredibly untransparent have no idea query , how.

obviously i'd happiest unhacked views solution, i'm not getting hopes up. experience relations this?

you can build dependent relationships should accomplish this. use relationship (artwork) on exhibition.artworks , relationship (artist) on (artwork).artist

it easier understand you're doing exports of views & content types.

the database structure content types in drupal works follows;

the node base table, nid index. content types have own tables, content_type_xxxxxx single entry fields (that aren't shared among content types) members of table. multiple entry , shared fields own table content_field_xxxxxx. of tables relate on nid field, , multiple entry fields use "delta" indicate entry order.

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
