c++ - Cannot compile when trying to utilize boost::asio::signal_set -

-

i'm using mingw 4.5.1 compiling client application (c++, windows xp) utilizing newest version of boost 1_47. reason can't seem determine, when go compile using boost::asio::signal_set type compile error (boost::asio::signal_set not define type), , when trying explicitly include either of associated signal_set headers, complaints of no file can found (despite file indeed being expected). have tried including files within same level of directory tree without issue, seems hang on signal_set.hpp file (although no complaints when using full header asio.hpp has include). same behavior when trying use boost 1_46_1 well.

might have insights going on?

the issue had was not including boost headers thought was. have boost installation in directory on hard drive, c:\boost\some_boost_version. whereas thought pointing new boost version's includes @ c:\boost\boost-1_47\boost, there not level inside directory tree \boost, in c:\boost\boost-1_47. adding new directory (created c:\boost\boost-1_47\boost) , putting includes within that, problem resolved. overlooked when retooled build scripts build boost libraries on machine.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
