.net - Unit testing with NUnit and Console -

-

i've been playing around curses sharp library (a c# wrapper pdcurses), writing unit test code handle on api , how works, , i've come question.

i can run curses sharp within dll (so nunit can test it), using following code:

        bool consoleallocated = allocconsole();         if (!consoleallocated)             throw new exception("unable allocate new console.");          curses.initscr();          stdscr.add(4, 6, "this test title");          curses.endwin();          freeconsole();

allocconsole , freeconsole extern's imported kernel32.

what able read console output position 4,6 string programmatically check string i've entered has been output correctly. pretty important able checks in order create curses-style app using tdd instance.

i've looked on curses , stdscr objects (both curses sharp objects), , console object (from windows library) , haven't been able find way yet. have ideas?

i managed find answer, in case interested i've included code below. it's messy, haven't cleaned yet, should serve example how this.

thanks pinvoke.net excellent signature collection.

    [dllimport("kernel32", setlasterror = true)]     static extern bool allocconsole();      [dllimport("kernel32", setlasterror = true)]     static extern bool freeconsole();      [dllimport("kernel32", setlasterror = true)]     static extern intptr getstdhandle(int nstdhandle);      [dllimport("kernel32", setlasterror = true)]     static extern bool readconsoleoutputcharacter(intptr hconsoleoutput,         [out]stringbuilder lpcharacter, uint nlength, coord dwreadcoord,         out uint lpnumberofcharsread);      const int std_output_handle = -11;      [structlayout(layoutkind.sequential)]     struct coord     {         public short x;         public short y;     }      [test]     public void writetitle()     {         bool consoleallocated = allocconsole();         if (!consoleallocated)             throw new exception("unable allocate new console.");          curses.initscr();          stdscr.add(4, 6, "this test title");         stdscr.refresh();          intptr stdout = getstdhandle(std_output_handle);         uint length = 20;         stringbuilder consoleoutput = new stringbuilder((int)length);         coord readcoord;         readcoord.x = 6;         readcoord.y = 4;         uint numofcharsread = 0;          readconsoleoutputcharacter(stdout, consoleoutput, length, readcoord, out numofcharsread);          string outputstring = consoleoutput.tostring();         assert.that(outputstring, is.equalto("this test title"));          curses.endwin();          freeconsole();     }

c# - How to set Z index when using WPF DrawingContext? -

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...
