using com dll

[adam.com]

in vs2010 c++ i used the following code to use some functions in a dll file that i don't have its header

#import "dll path"
HRESULT hr = CoInitialize(NULL);
if (hr==S_OK)
{cout<<"INITIALIZED\n";}
 
Trans_ATLLib::ITransCriptPtr Trans;
hr = Trans.CreateInstance(__uuidof(Trans_ATLLib::TransCript));
if (hr==S_OK)
{cout<<"INSTANCE CREATED\n";}
 
hr =Trans->EnableLastCharTashkeel(true);
if (hr==S_OK)
{cout<<"EnableLastCharTashkeel DONE\n";}
 
hr =Trans->EnableEmphaticLAM_RAA(true);
if (hr==S_OK)
{cout<<"EnableEmphaticLAM_RAA DONE\n";}
 
VARIANT_BOOL test;
test = Trans->SetText(arabic_string);
if (test==0)
{cout<<"error in setting the arabic sting\n";}
 
string result;
result = Trans->GetResult();
 
istringstream iss(result);
vector<string> phonemes;
copy(istream_iterator<string>(iss),istream_iterator<string>(),back_inserter<vector<string> >(phonemes));
return phonemes;
 
}

#import "dll path"
HRESULT hr = CoInitialize(NULL);
if (hr==S_OK)
{cout<<"INITIALIZED\n";}

Trans_ATLLib::ITransCriptPtr Trans;
hr = Trans.CreateInstance(__uuidof(Trans_ATLLib::TransCript));
if (hr==S_OK)
{cout<<"INSTANCE CREATED\n";}

hr =Trans->EnableLastCharTashkeel(true);
if (hr==S_OK)
{cout<<"EnableLastCharTashkeel DONE\n";}

hr =Trans->EnableEmphaticLAM_RAA(true);
if (hr==S_OK)
{cout<<"EnableEmphaticLAM_RAA DONE\n";}

VARIANT_BOOL test;
test = Trans->SetText(arabic_string);
if (test==0)
{cout<<"error in setting the arabic sting\n";}

string result;
result = Trans->GetResult();

istringstream iss(result);
vector<string> phonemes;
copy(istream_iterator<string>(iss),istream_iterator<string>(),back_inserter<vector<string> >(phonemes));
return phonemes;

}

To copy to clipboard, switch view to plain text mode 

but i found that qt doesn't use the same method

can any one help me in calling these functions in qt

thanks in advance
