#import "C:\WINDOWS\system32\msado15.dll"no_namespace
int _stdcall KMT_start(int devType, char uid[], char fw[], char chip[], int tune, char kmtINI[], long len[])
{
BSTR bstrDesc,str;
// SysFreeString(str);
str=_com_util::ConvertStringToBSTR(str1);
try
{
CoInitialize(NULL);
_Class1Ptr ptr=NULL;
ptr.CreateInstance(__uuidof(Class1));
if(ptr==0)
{
AfxMessageBox("无效的指针");
return 0;
}
ptr->KMT_app_start(&str);
}
catch(_com_error &e)
{
bstrDesc = e.Description();
}
CoUninitialize();
return 0;
}
