Opening Excel with a stream
The only way I know is to open Excel workbook from
commandline.
Shell(ExcelPath & " " & bstrFile & " /cmd " & vopt1 & " "
& vopt2 & " " & voptn)

Hi All,
I am trying to get Excel to open using the contents of a
stream that I
have populated from a database. Are there any
samples/examples I can
review /
The code looks something like this (although I have
removed error
handling for clarity):
ADO::_RecordsetPtr pRS("ADODB.Recordset",false);
_variant_t vRows;
_bstr_t bstrSelect("SELECT * from MyTable where name
= 'Mysheet'");
pRS = m_pConn-Execute(bstrSelect, &vRows,0);
ADO::_StreamPtr pStr("ADODB.Stream");
pStr-Type = ADO::adTypeBinary;
pStr-Open
(vtMissing,ADO::adModeUnknown,ADO::adOpenStreamUns pecified,
"","");
pStr-Write(pRS-GetFields()-GetItem((_variant_t)"DATA")-
GetValue());
This works as I can use the following to open the
spreadsheet
_bstr_t bstrFile("C:\Tmp\MySheet.xls");
pStr-SaveToFile(bstrFile,ADO::adSaveCreateNotExist);
LPDISPATCH lpDisp;
m_app.CreateDispatch("Excel.Application")lpDisp =
m_app.GetWorkbooks();
ASSERT(lpDisp);
m_books.AttachDispatch(lpDisp);
m_books.Open
(bstrFile,vOpt,vOpt,vOpt,vOpt,vOpt,vOpt,vOpt,vOpt, vOpt,vOpt
,vOpt,vOpt);
.
