Function is inside the webbrowser click login button, text access to elements in traverse elements, get_innerText () collapse,
First this in the main line, write not in the thread, I have been at the beginning of the thread added CoInitializeEx (0, COINIT_APARTMENTTHREADED);

Specific code:

 
//take out the eligible elements of traverse webbrowser 
IHTMLElement * getElementByName (CComQIPtr{
CComQIPtr PelColl; 
Retrieves the hr=pDoc3 - & gt; The getElementsByTagName ((_bstr_t) tagName, & amp; PelColl); 
If (FAILED (hr) | | pelColl==NULL) 
{
return NULL; 
} 

Long len=0; 
PelColl - & gt; Get_length (& amp; Len); 

For (long I=0; I & lt; Len. I++) 
{
_variant_t index=I; 
Pdisp IDispatch *=NULL; 
PelColl - & gt; The item (index, index, & amp; Pdisp); 
If (pdisp==NULL) 
{
continue; 
} 
Pele IHTMLElement *=NULL; 
Pdisp - & gt; QueryInterface (IID_IHTMLElement, (LPVOID *) (& amp; Pele)); 
If (pele) 
{
BSTR b; 
//here collapse, & amp; The value of b is 0 XCCCCCCCC 
Pele - & gt; Get_innerText (& amp; B); 
_bstr_t BSTR=b; 
If (BSTR. Length () & amp; & STRCMP (BSTR, name)==0) 
{
Return pele. 
} 
Pele - & gt; Release (); 
} 
Pdisp - & gt; Release (); 

} 

return NULL; 
} 

//thread function 
DWORD __stdcall threadLoginbd (LPVOID lp) 
{
Retrieves the hr=CoInitializeEx (0, COINIT_APARTMENTTHREADED); 
If (FAILED (hr)) 
{
TRACE (" 1 "); 
} 

PDlg CwebbrowserDlg *=(CwebbrowserDlg *) lp; 
CExplorer1 * pIe=& amp; (pDlg - & gt; M_ie); 

CComQIPtr
//get elements and then click 
Pele IHTMLElement *=getElementByName (pDoc3, "a", "login"); 
If (pele) 
{
Pele - & gt; Click (); 
Pele - & gt; Release (); 
TRACE (" 3 "); 
} 

CoUninitialize (); 
return 0; 
} 

Don't understand defines a BSTR b, how is the address of the 0 XCCCCCCCC,
