Body
I am developing an ADO application (32 bit) on Windows 7 64 bit SP1 (all updates installed): The app must run on Win XP. According to <a href="http://support.microsoft.com/kb/2517589/en-us" rel="nofollow">http://support.microsoft.com/kb/2517589/en-us</a> I am using msado60_backcompat. That worked well until lately, but now it crashes. My code (snippets): <pre><code>_CommandPtr cmd(__uuidof(Command)); cmd->ActiveConnection = dbconn; cmd->CommandText = _T("SELECT [si] FROM [TTable] WHERE [TTable].[ti1]=?"); cmd->Parameters->Append(cmd->CreateParameter(L"@ti1", adTinyInt, adParamInput, 1, 7)); </code></pre> CreateParameter is implemented in msado60_backcompat: <pre><code>inline _ParameterPtr Command15::CreateParameter ( _bstr_t Name, enum DataTypeEnum Type, enum ParameterDirectionEnum Direction, ADO_LONGPTR Size, const _variant_t & Value ) { struct _Parameter * _result = 0; HRESULT _hr = raw_CreateParameter(Name, Type, Direction, Size, Value, &_result); if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this)); return _ParameterPtr(_result, false); } </code></pre> raw_CreateParameter() calls into msado15.dll into CCommand::CreateParameter. There a crash occurs at offset 0x34f (offset inside the function): <blockquote> First-chance exception at 0x655ed5a6 (msado15.dll) in adosqlbugcheck.exe: 0xC0000005: Access violation writing location 0xcccccccc. Unhandled exception at 0x655ed5a6 (msado15.dll) in adosqlbugcheck.exe: 0xC0000005: Access violation writing location 0xcccccccc. </blockquote> Msado60_Backcompat.tlb: 73728 bytes, 29.4.2011 msado15.dll: 6.1.7601.17514, 1019904 bytes, 21.11.2010 The error does not occur if I use msado15.dll. Can someone reproduce the error? Is there a solution?

Guidance

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.
