svg - getSVGDocument repeatedly throwing "0x80020003 - JavaScript runtime error: Member not found" -


the uk office national statistics provide access data uk 2011 national census. 1 access method provide through soap api , give examples of how consume api on page ness data exchange v2.0. having trouble getting 1 example working. it’s under nde v2.0 excel client in zip nde hub client rest v2.0 (zip) 37 mb, "hub demo excel-based application allows user build repository of saved data, , view via svg thematic map".

the map <div> svg data added page these lines (in 'sources/thematicmap.htm')

document.writeln('<div id=mappanel style="position:absolute;left:26%;top:7%; height=63%; width=50%;">') document.writeln('<embed height=100% width=100% name=svgmap src="../boundaries/' + svgfile + '" type=image/svg-xml>') document.writeln('</div>');

(n.b. original code ..\\boundaries\\ changed ../boundaries/. both lead same error.)

putting breakpoint on middle line reveals svgfile variable set "la_12ub.svg" , file present in 'boundaries' directory. here how 'boundaries/la_12ub.svg' starts.

i.e. appears correctly formed , full of svg data.

'sources/thematicmap.htm' contains line 

<body onload="initialise()">

that calls initialise in 'includes/startup.js'. initialise exception thrown. when code reaches line 

svgmapdoc = document.svgmap.getsvgdocument();

the error 0x80020003 - javascript runtime error: member not found raised. setting breakpoint can see document.svgmap not null nor undefined, though appear full of default values rather wealth of path data i’d expect (but i’m not sure that).

the question how check if embedded svg document loaded in html page? may relevant. cannot use erik dahlström's answer since rely on onload suggests. have tried mocky's answer thus

function checksvgmapready() {     try {         svgmapdoc = document.svgmap.getsvgdocument();     } catch (e) { }     if (svgmapdoc === undefined) {         settimeout("checksvgmapready()", 300);     } else {         svgmapready();     } }

but each time through iterative call same error caught.

(n.b. think examples tested ie6, ie7, firefox 2, @ least readme file in of examples states, while using ie10. have tried chrome , firefox too, , while not see same error message not see svg data rendered either.)

does have idea why call getsvgdocument throwing 0x80020003 - javascript runtime error: member not found , how fix it?

there seem number of issues here.

type=image/svg-xml invalid. must use type=image/svg+xml.

then think should try doing this...

  if (document.svgmap && document.svgmap.contentdocument)     svgmapdoc = document.svgmap.contentdocument;   else try {     svgmapdoc = document.svgmap.getsvgdocument();   }   catch(exception) {     alert('neither htmlobjectelement nor getsvgdocument interface implemented');   }

finally code initialise svgmapdoc called onload event of body, should onload of embed triggers somehing this...

document.writeln('<embed height=100% width=100% onload="initialise()" name=svgmap src="../boundaries/' + svgfile + '" type=image/svg+xml>')

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
