Small white a ah, trouble can point in detail, now in use COM components

 CoInitialize (NULL); 
IDFTCOM * pImDFT; 
Retrieves the hr=CoCreateInstance (CLSID_DFTCOM, NULL, CLSCTX_ALL, IID_IDFTCOM, (void * *) & amp; PImDFT); 
COleVariant CTRL; 
CTRL=0 (double); 
PImDFT - & gt; Guitest1 (CTRL) (VARIANT); This newspaper called function too little 
Guitest1 (lambda, CTRL);//call the COM components to produce an invisible Figure window this undefined guitest1 and lambda 
Char FigName []="_guitest_"; 
HWND hFig=: : FindWindow (NULL, FigName); 
Long lStyle=: : GetWindowLong (hFig GWL_STYLE); 
: : SetWindowLong (hFig, GWL_STYLE lStyle& (~ WS_CAPTION) & amp; (~ WS_THICKFRAME)); 
: : SetWindowPos (hFig, NULL, 0,0,0,0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_NOACTIVATE | SWP_FRAMECHANGED); 
The RECT PlotRec; 
The CWnd * PlotArea=GetDlgItem (IDC_STATIC); 
PlotArea - & gt; GetWindowRect (& amp; PlotRec); 
The long Width=PlotRec. Right - PlotRec. Left; 
Long Height=PlotRec. Bottom - PlotRec. Top; 
: : SetParent (hFig PlotArea - & gt; GetSafeHwnd ()); 
: : SetWindowPos (hFig, NULL, 1, 1, Width, Height, SWP_NOZORDER | SWP_NOACTIVATE); 
CTRL=(double) 1; 
PImDFT - & gt; Guitest1 (CTRL) (VARIANT); This newspaper called function too little 

Thank you will answer, their own learning, in a hurry with ~
