long flcid = 0;
ExcelApplication1->Connect();
ExcelApplication1->set_Visible(flcid,1);
ExcelApplication1->set_UserControl(1);

tagVARIANT t = EmptyParam;

wchar_t * FileName = L"c:\\local.xls";
ExcelWorkbook1->ConnectTo(ExcelApplication1->Workbooks->Open(FileName,t,t,t,t,t,t,t,t,t,t,t,t,flcid));

Der Fehler ist:

HRCHECK: (this->Open(Filename,UpdateLinks,ReadOnly,Format,Password;WriteResPassword,IgnoreReadOnlyRecommended,Origin,Delimiter,Editable,Notify,Converter,AddToMru,lcid, (Excel_2k::ExcelWorkbook**)&RHS)) Error: 800A03EC (-2146827284) @ c:\programme\borland\cbuilder6\include\vcl\Excel_2k.h/12990

Wenn ich flcid auf 1 stelle, dann erhalte ich:

HRCHECK: this->Open(Filename,UpdateLinks,ReadOnly,Format,Password;WriteResPassword,IgnoreReadOnlyRecommended,Origin,Delimiter,Editable,Notify,Converter,AddToMru,lcid, (Excel_2k::ExcelWorkbook**)&RHS): Altes Format oder ungültige Typbibliothek. @ c:\programme\borland\cbuilder6\include\vcl\Excel_2k.h/12990

Es sei hingewiesen, dass ich Office 2007 hier installiert habe. Kann das damit was zu tun haben?
