Julia graphs, dijkstra_shortest_paths -

-

i have expandable graph, being able add vertices , edges, , run dijkstra_shortest_paths algo. not able find right way define graph dijkstra_shortest_paths work. below attempt.

using graphs g1= graph(exvertex[], exedge{exvertex}[], is_directed=false) dist_key = "dist" v1 = add_vertex!(g1, "a") v2 = add_vertex!(g1, "b") v3 = add_vertex!(g1, "c") e12 = add_edge!(g1, v1, v2) e12.attributes[dist_key]=1.0 e13 = add_edge!(g1, v1, v3) e13.attributes[dist_key]=1.0 e23 = add_edge!(g1, v2, v3) e23.attributes[dist_key]=1.0 epi = attributeedgepropertyinspector{float64}(dist_key) dijkstra_shortest_paths(g1, epi, ["a"])

error message:

dijkstra_shortest_paths has no method matching   dijkstra_shortest_paths(::genericgraph{exvertex,exedge{exvertex},array{exvertex,1},array{exedge{exvertex},1},array{array{exedge{exvertex},1},1}}, ::attributeedgepropertyinspector{float64}, ::array{asciistring,1})

i think problem ["a"] - have refer actual vertex "manually", i.e.

julia> sp = dijkstra_shortest_paths(g1, epi, [v1]) julia> sp.parents 3-element array{exvertex,1}:  vertex [1] "a"  vertex [1] "a"  vertex [1] "a" julia> sp.dists 3-element array{float64,1}:  0.0  1.0  1.0

works me.

i'm working on automating windows application. i'm using teststack white framework. i've hit problem. program has 'window' object cannot see inside of. white shows no controls inside of it. inspect.exe shows no controls inside of either when running in ui automation mode. if switch inspect msaa see controls inside fine. there anyway me use msaa c# handle on these controls? if can identify msaa functions need, can use p/invoke call them c#. here's example article doing msaa: http://www.codeproject.com/articles/38906/ui-automation-using-microsoft-active-accessibility also, pinvoke.net can used identify iaccessible (msaa) functions: http://www.pinvoke.net/search.aspx?search=iaccessible&namespace=[all] here's answer along lines: msaa com-based? finally, alternative p/invoke, might able use tlbimp.exe create wrapper assembly oleacc.dll, , access msaa functions through it. i'm not sure if works msaa, it's worth try. as e...
