    <p>I am a newbie to C++. I want to get the content of the clipboard, which might contain Unicode chars, append a div tag with some content formatted in HTML and set that back to clipboard.</p> <p><em>I have achieved successfully in getting the content and appending it.</em> But could not set it back to the <em>clipboard as an HTML text</em>. I have achieved setting as simple text. Here is my code:</p> <pre class="lang-cpp prettyprint-override"><code>#include &lt;shlwapi.h&gt; #include &lt;iostream&gt; #include &lt;conio.h&gt; #include &lt;stdio.h&gt; using namespace std; wstring getClipboard(){ if (OpenClipboard(NULL)){ HANDLE clip = GetClipboardData(CF_UNICODETEXT); WCHAR * c; c = (WCHAR *)clip; CloseClipboard(); return (WCHAR *)clip; } return L""; } bool setClipboard(wstring textToclipboard) { if (OpenClipboard(NULL)){ EmptyClipboard(); HGLOBAL hClipboardData; size_t size = (textToclipboard.length()+1) * sizeof(WCHAR); hClipboardData = GlobalAlloc(NULL, size); WCHAR* pchData = (WCHAR*)GlobalLock(hClipboardData); memcpy(pchData, textToclipboard.c_str(), size); SetClipboardData(CF_UNICODETEXT, hClipboardData); GlobalUnlock(hClipboardData); CloseClipboard(); return true; } return false; } int main (int argc, char * argv[]) { wstring s = getClipboard(); s += std::wstring(L"some extra text &lt;b&gt;hello&lt;/b&gt;"); setClipboard(s); getch(); return 0; } </code></pre> <p>I did try using the code described <a href="http://support.microsoft.com/kb/274308" rel="nofollow">here</a> and read the doc <a href="http://msdn.microsoft.com/en-us/library/aa767917.aspx" rel="nofollow">here</a>. But I couldn't make it work. What I tried could be way off track or completely wrong. </p> <p><strong>Update:</strong> The code below is what I tried after the modifications suggested by Cody Gray to the original code presented <a href="http://support.microsoft.com/kb/274308" rel="nofollow">here</a>:</p> <pre class="lang-cpp prettyprint-override"><code>bool CopyHTML2(WCHAR *html ){ wchar_t *buf = new wchar_t [400 + wcslen(html)]; if(!buf) return false; static int cfid = 0; if(!cfid) cfid = RegisterClipboardFormat("HTML Format"); // Create a template string for the HTML header... wcscpy(buf, L"Version:0.9\r\n" L"StartHTML:00000000\r\n" L"EndHTML:00000000\r\n" L"StartFragment:00000000\r\n" L"EndFragment:00000000\r\n" L"&lt;html&gt;&lt;body&gt;\r\n" L"&lt;!--StartFragment --&gt;\r\n"); // Append the HTML... wcscat(buf, html); wcscat(buf, L"\r\n"); // Finish up the HTML format... wcscat(buf, L"&lt;!--EndFragment--&gt;\r\n" L"&lt;/body&gt;\r\n" L"&lt;/html&gt;"); wchar_t *ptr = wcsstr(buf, L"StartHTML"); wsprintfW(ptr+10, L"%08u", wcsstr(buf, L"&lt;html&gt;") - buf); *(ptr+10+8) = L'\r'; ptr = wcsstr(buf, L"EndHTML"); wsprintfW(ptr+8, L"%08u", wcslen(buf)); *(ptr+8+8) = '\r'; ptr = wcsstr(buf, L"StartFragment"); wsprintfW(ptr+14, L"%08u", wcsstr(buf, L"&lt;!--StartFrag") - buf); *(ptr+14+8) = '\r'; ptr = wcsstr(buf, L"EndFragment"); wsprintfW(ptr+12, L"%08u", wcsstr(buf, L"&lt;!--EndFrag") - buf); *(ptr+12+8) = '\r'; // Open the clipboard... if(OpenClipboard(0)) { EmptyClipboard(); HGLOBAL hText = GlobalAlloc(GMEM_MOVEABLE |GMEM_DDESHARE, wcslen(buf)+4); wchar_t *ptr = (wchar_t *)GlobalLock(hText); wcscpy(ptr, buf); GlobalUnlock(hText); SetClipboardData(cfid, hText); CloseClipboard(); GlobalFree(hText); } // Clean up... delete [] buf; return true; } </code></pre> <p>This code compiles successfully, But I get the following error at SetClipboardData : <code>HEAP[Project1.exe]: Heap block at 007A8530 modified at 007A860A past requested size of d2 Project1.exe has triggered a breakpoint.</code></p> <p>Please guide me on how to proceed. I am using Visual Studio Express 2012 on Windows 8. Thanks.</p>

    3. CODo you have unicode enabled for your program? It seems that the ``wsprintf`` here use the ANSI version, i.e. ``wsprintfA``, which accepts ``LPSTR``, i.e. ``char *``.

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).
