ERROR_SXS_KEY_NOT_FOUND-CreateDispatch fails in createthread

[sudhakar]

Hello ,

I created a MFC Dialog based application and then using class wizard created
Automation classes for excel.

I'm able to call the Automation object using the function CreateDispatch
function and it starts the excel.exe. This is fine. Code is below

void OnRun()
{

COleException *excp = new COleException;
CString s , err;
s.Empty();
//GetDlgItem(IDC_APPEDIT)->GetWindowText(s);
// Start Excel and get Application object...Excel.Application
if( app.CreateDispatch("Excel.Application" , excp) == FALSE )
{
err.Empty();
err.Format(" Error: %d",GetLastError());
AfxMessageBox(err);
}
else
{
//Make Excel Visible and display a message
app.SetVisible(TRUE);
err.Empty();
err.Format("%s is Running!!",s);
AfxMessageBox (err);

}

But the same part of the above code , if it is being called from
CreateThread like the below code, , it returns error code 14007

DWORD dwThreadId;
HANDLE hThread =
CreateThread(0,0,DIAdemInstanceThread,(LPVOID)this,0,&dwThreadId);

DWORD WINAPI DIAdemInstanceThread(LPVOID lpParam)
{
_Application app;
COleException *excp = new COleException;
CString s , err;
s.Empty();
// Start Excel and get Application object...Excel.Application
if( app.CreateDispatch("Excel.Application" , excp) == FALSE )
{
err.Empty();
err.Format(" Error: %d",GetLastError());
AfxMessageBox(err);
}
else
{
//Make Excel Visible and display a message
app.SetVisible(TRUE);
err.Empty();
err.Format("%s is Running!!",s);
AfxMessageBox (err);
}

return 0;
}
Details of the Win32 Error code;
