我用C＋＋Builder6做了一个COM＋程序，安装到了COM＋环境中。COM+中定义了几个函数，参数有in和in&out类型，我现在想做一个SOAP server程序调用这些函数，用了CreateOleObject等函数，也考虑到了函数参数等问题：
Variant vDODemo;
OleVariant sData;
CoInitialize(NULL);
// OleInitialize(NULL);
try
{
vDODemo = CreateOleObject("TDM1.TDM1");
vDODem
lePropertySet("SQL",sSQL);
vDODemlePropertySet("Data",AnsiString(sData));
vDODemleFunction("QueryHjData");
/// Function QueryHjData("QueryHjData");
/// QueryHjData << NamedParm("SQL",sSQL) << NamedParm("Data",AnsiString(sData));
/// vDODemo.Exec(QueryHjData);
// vDODemo.QueryHjData(sSQL, sData);
// return sData;
}
__finally
{
CoUninitialize();
//OleUninitialize();
}
编译通过，但是连接时报错，怎么回事？
