proxy - In Delphi 7, how can I retrieve Internet Connection names list? -

-

earlier ask how can set internet proxy in windows connection.

but problem if want set connections, must list connection names list. search on net can't find answer this.

you're looking rasenumentries function. delphi doesn't have ras api functions declared, easy if you've got jvcl. tjvras32 component has phonebook tstrings property in available connections populated.

below d2007 test code (no error checking):

const   ras_maxentryname = 256;   rasbase = 600;   error_buffer_too_small = rasbase + 3;   error_invalid_size = rasbase + 32;  type   prasentryname = ^trasentryname;   trasentryname = record     dwsize: longint;     szentryname: array [0..ras_maxentryname] of char;   end;  function rasenumentriesa(reserved: pchar; lpszphonebook: pchar;           lprasentryname: prasentryname; var lpcb: dword;           var lpcentries: dword): dword; stdcall; external 'rasapi32.dll';  procedure getrasentries(list: tstrings); var   rasentrynames: array of trasentryname;   err, size, entries: dword;   i: integer; begin   list.clear;   setlength(rasentrynames, 1);   size := sizeof(trasentryname);   rasentrynames[0].dwsize := size;   err := rasenumentriesa(nil, nil, @rasentrynames[0], size, entries);   if (err = error_buffer_too_small) , (entries > 0) begin     assert(size = sizeof(trasentryname) * entries);     setlength(rasentrynames, entries);     err := rasenumentriesa(nil, nil, @rasentrynames[0], size, entries);     if err = 0       := 0 length(rasentrynames)         list.add(rasentrynames[i].szentryname);   end else     list.add(rasentrynames[0].szentryname); end;   procedure tform1.button1click(sender: tobject); begin   getrasentries(listbox1.items); end;

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...

(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...
