Opengl glGenVertexArrays error -

-

i trying make 5 vertex array objects(vao) using 1 array init() function.

however, glgenvertexarrays( 5, &vao ) throws me error , don't understand why does.

i guess don't understand behavior of function.

can tell me what's going on here?

here original code:

void init(){   // subdivide tetrahedron sphere   index = 0; tetrahedron( 1, 0, numtimestosubdivide-4 );   index = 0; tetrahedron( 0, 1, numtimestosubdivide-3 );   index = 0; tetrahedron( 0, 2, numtimestosubdivide-2 );   index = 0; tetrahedron( 0, 3, numtimestosubdivide-1);   index = 0; tetrahedron( 0, 4, numtimestosubdivide );    // create vertex array object   **glgenvertexarrays( 5, &vao ); // error occurs on line**   ( int i=0; i<5; i++ )   {      glbindvertexarray( vao[i] );      gluint buffer;     glgenbuffers( 1, &buffer );     glbindbuffer( gl_array_buffer, buffer );     glbufferdata( gl_array_buffer, sizeof(points[i]) + sizeof(normals[i]),null, gl_static_draw );     glbuffersubdata( gl_array_buffer, 0, sizeof(points[i]), &(points[i]) );     glbuffersubdata( gl_array_buffer, sizeof(points[i]),sizeof(normals[i]), &(normals[i]) );   }   // load shaders , use resulting shader program   gluint program = initshader( "vshader.glsl", "fshader.glsl" );   gluseprogram( program );    // set vertex arrays   gluint vposition = glgetattriblocation( program, "vposition" );   glenablevertexattribarray( vposition );   glvertexattribpointer( vposition, 4, gl_float, gl_false, 0, buffer_offset(0) );    gluint vnormal = glgetattriblocation( program, "vnormal" );   glenablevertexattribarray( vnormal );   glvertexattribpointer( vnormal, 3, gl_float, gl_false, 0, buffer_offset(sizeof(points)) );    ambientproduct = glgetuniformlocation(program, "ambientproduct");   diffuseproduct = glgetuniformlocation(program, "diffuseproduct");   specularproduct = glgetuniformlocation(program, "specularproduct");   lightposition = glgetuniformlocation(program, "lightposition");   shininess = glgetuniformlocation(program, "shininess");   transformation = glgetuniformlocation( program, "transformation" );   view = glgetuniformlocation( program, "view" );   projection = glgetuniformlocation( program, "projection" );    glenable( gl_depth_test );   glclearcolor(0.0, 0.0, 0.0, 0.0 ); /* black background */ }

here error messages:

error c2664: 'void (glsizei,gluint *)' : cannot convert parameter 2 'gluint (*)[5]' 'gluint *' 1>          types pointed unrelated; conversion requires reinterpret_cast, c-style cast or function-style cast  error c2664: 'void (glsizei,gluint *)' : cannot convert parameter 1 'gluint (*)[5]' 'glsizei' 1>          there no context in conversion possible

arrays pointers. don't need &:

glgenvertexarrays( 5, vao );

reactjs - React router and this.props.children - how to pass state to this.props.children -

i'm using react-router first time , don't know how think in yet. here's how i'm loading components in nested routes. entry point .js reactdom.render( <router history={hashhistory} > <route path="/" component={app}> <route path="models" component={content}> </route> </router>, document.getelementbyid('app') ); app.js render: function() { return ( <div> <header /> {this.props.children} </div> ); } so child of app content component sent in. i'm using flux , app.js has state , listens changes, don't know how pass state down this.props.children. before using react-router app.js defines children explicitly, passing state natural don't see how now. using couple of react helper methods can add state, props , whatever else this.props.children render: function() { var children = react.ch...

i have excel workbook used generate quotations customers. there main page user inputs data, , there buttons generate various pdfs , send them customer. however, 1 user consistently getting error preventing generating , sending pdfs. i beleive "microsoft windows common controls 6.0 (sp6)". it's installed on users' computers. on mine, location "c:\windows\syswow64\mscomctl.ocx" on others "c:\windows\system32\mscomctl.ocx" the user experiencing issues on 32-bit machine, "mscomctl.ocx" file should in system32. have manually put in there, , pointed common controls reference in vba it. issue seems keep reverting looking in syswow64. since folder doesn't exist, can't find it, , can't produce pdfs. i thought perhaps issue user running older version of office (2007) there users on 2013 , 2016. thought perhaps mixture of 64-bit , 32-bit users. user gets sent workbook other users (as quotation process goes further, gets passed ...
