    <p>I have 2 <code>CRichEditCtrls</code>. One is part of a dialog template, created automatically. When I call GetSelText on it, the bytes returned are one byte per char, i.e I'll get back <code>char *str={'a','n','d'}</code>. The 2nd control is created dynamically using the <code>Create</code> method, and the data returned calling GetSelText is returned in 2-byte characters: <code>char *str={'a',0,'n',0,'d',0}</code>.</p> <p>This is making things a real pain... see <a href="https://stackoverflow.com/questions/2333684/cricheditctrlgetseltext-is-not-working-right">this topic</a>. One way works with one control, one way works with the other.</p> <p>I can't even see <em>how</em> two controls (on the same dialog) can have different behavior like this. I don't see a way to tell the one created dynamically what way to work.</p> <p>How can this be going on? The control created dynamically is the odd one out in our application, so that's the one that needs to be changed...</p> <p>Here is the code I'm using:</p> <pre><code>ASSERT(::IsWindow(m_hWnd)); CHARRANGE cr; cr.cpMin = cr.cpMax = 0; ::SendMessage(m_hWnd, EM_EXGETSEL, 0, (LPARAM)&amp;cr); CString strText; LPTSTR lpsz=strText.GetBufferSetLength((cr.cpMax - cr.cpMin + 1) * 2); lpsz[0] = NULL; long nLen = ::SendMessage(m_hWnd, EM_GETSELTEXT, 0, (LPARAM)lpsz); lpsz[nLen] = NULL; for(long i=0;i&lt;nLen;++i) { TRACE("lpsz[%d] (%d bytes) = %d {",i,sizeof(lpsz[i]),lpsz[i]); char *pc = (char *)&amp;lpsz[i]; for(int j=0;j&lt;sizeof(lpsz[i]);++j) { TRACE(" %d(%c)",pc[j],pc[j] ? pc[j] : '#'); } TRACE("}\n"); } strText.ReleaseBuffer(); return CString(strText); </code></pre> <p>The output from my dialog-template control:</p> <pre><code>lpsz[0] (2 bytes) = 28257 { 97(a) 110(n)} lpsz[1] (2 bytes) = 100 { 100(d) 0(#)} lpsz[2] (2 bytes) = 52685 { -51(Í) -51(Í)} </code></pre> <p>And from my dynamically created control:</p> <pre><code>lpsz[0] (2 bytes) = 97 { 97(a) 0(#)} lpsz[1] (2 bytes) = 110 { 110(n) 0(#)} lpsz[2] (2 bytes) = 100 { 100(d) 0(#)} </code></pre>

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.
