    <p>im tyring to get this to work:</p> <pre><code> #define UNICODE #define _UNICODE #include &lt;wchar.h&gt; int main() { wprintf(L"Hello World!\n"); wprintf(L"£안, 蠀, ☃!\n"); return 0; } </code></pre> <p>using visual studio 2008 express (on windows xp, if it matters). when i run this from the command prompt (started as cmd /u which is supposed to enable unicode ?) i get this:</p> <pre> C:\dev\unicodevs\unicodevs\Debug>unicodevs.exe Hello World! ┬ú∞ C:\dev\unicodevs\unicodevs\Debug> </pre> <p>which i suppose was to be expected given that the terminal does not have the font to render those. but what gets me is that even if i try this:</p> <pre> C:\dev\unicodevs\unicodevs\Debug>cmd /u /c "unicodevs.exe > output.txt" </pre> <p>the file produced (even though its UTF-8 encoded) looks like:</p> <pre> Hello World! £ì </pre> <p>the source file itself is defined as unicode (encoded in UTF-8 without BOM). the compiler output when building:</p> <pre> 1>------ Rebuild All started: Project: unicodevs, Configuration: Debug Win32 ------ 1>Deleting intermediate and output files for project 'unicodevs', configuration 'Debug|Win32' 1>Compiling... 1>main.c 1>.\main.c(1) : warning C4005: 'UNICODE' : macro redefinition 1> command-line arguments : see previous definition of 'UNICODE' 1>.\main.c(2) : warning C4005: '_UNICODE' : macro redefinition 1> command-line arguments : see previous definition of '_UNICODE' 1>Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\wchar.h 1>Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\crtdefs.h 1>Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\sal.h 1>C:\Program Files\Microsoft Visual Studio 9.0\VC\include\sal.h(108) : warning C4001: nonstandard extension 'single line comment' was used 1>Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\crtassem.h 1>Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\vadefs.h 1>Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\swprintf.inl 1>Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\wtime.inl 1>Linking... 1>Embedding manifest... 1>Creating browse information file... 1>Microsoft Browse Information Maintenance Utility Version 9.00.30729 1>Copyright (C) Microsoft Corporation.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
