    <p>Hello I'm programming in Visual C++ 2010 (spanish) with UNICODE and /clr. I have a header file called "fileFuncs.h":</p> <pre><code>#include &lt;iostream&gt; #include &lt;fstream&gt; #include &lt;string&gt; #include &lt;stdlib.h&gt; #include &lt;string&gt; using namespace std; std::wstring s2ws(const std::string&amp; s) { int len; int slength = (int)s.length() + 1; len = MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, 0, 0); wchar_t* buf = new wchar_t[len]; MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, buf, len); std::wstring r(buf); delete[] buf; return r; } void callSystem(string sCmd){ std::wstring stemp = s2ws(sCmd); LPCWSTR params = stemp.c_str(); ShellExecute(NULL,L"open",L"c:\\windows\\system32\\cmd.exe /S /C ",params,NULL,SW_HIDE); } </code></pre> <p>But when I compile give me these errors:</p> <ul> <li><p>error LNK2028: refers to the unresolved symbol (token) (0A0004A5) "extern "C" struct HINSTANCE__ * <strong>stdcall ShellExecuteW(struct HWND</strong> *,wchar_t const *,wchar_t const *,wchar_t const *,wchar_t const *,int)" (?ShellExecuteW@@$$J224YGPAUHINSTANCE_<em>@@PAUHWND</em>_@@PB_W111H@Z) in the function "void __cdecl callSystem(class std::basic_string,class std::allocator >)" (?callSystem@@$$FYAXV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@</p></li> <li><p>error LNK2019: external symbol "extern "C" struct HINSTANCE__ * <strong>stdcall ShellExecuteW(struct HWND</strong> *,wchar_t const *,wchar_t const *,wchar_t const *,wchar_t const *,int)" (?ShellExecuteW@@$$J224YGPAUHINSTANCE_<em>@@PAUHWND</em>_@@PB_W111H@Z) unresolved referred to in "void __cdecl callSystem(class std::basic_string,classstd::allocator)" function (?callSystem@@$$FYAXV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z)</p></li> </ul> <p>Is some type of configuration?</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
