This example creates an IPB_Session with the simple library list
mydemo.pbl:

IPB_Session* session;
IPB_VM* vm = NULL;
fstream out; 
ifstream in;
PBXRESULT ret;

HINSTANCE hinst=LoadLibrary("pbvm.dll");
if ( hinst== NULL) return 0;

out&lt;&lt; "Loaded PowerBuilder VM successfully!"&lt;&lt;endl;

P_PB_GetVM getvm = (P_PB_GetVM)GetProcAddress
(hinst, "PB_GetVM");
if (getvm == NULL) return 0;

getvm(&amp;vm);
if (vm == NULL) return 0;

static const char *liblist[] = 
{
"mydemo.pbl"
};

ret= vm-&gt;CreateSession("mydemo", liblist, 1, &amp;session);
if (ret != PBX_OK) 
{
out &lt;&lt; "Create session failed." &lt;&lt; endl;
return 0;
}
out &lt;&lt; "Create session succeeded!" &lt;&lt;endl;

IPB_Session* session;

IPB_VM* vm = NULL;

fstream out;

ifstream in;

PBXRESULT ret;

HINSTANCE hinst=LoadLibrary("pbvm.dll");

if ( hinst== NULL) return 0;

out<< "Loaded PowerBuilder VM successfully!"<<endl;

P_PB_GetVM getvm = (P_PB_GetVM)GetProcAddress

(hinst, "PB_GetVM");

if (getvm == NULL) return 0;

getvm(&vm);

if (vm == NULL) return 0;

static const char *liblist[] =

{

"mydemo.pbl"

};

ret= vm->CreateSession("mydemo", liblist, 1, &session);

if (ret != PBX_OK)

{

out << "Create session failed." << endl;

return 0;

}

out << "Create session succeeded!" <<endl;
