Hi Erveryone!

I have got a problem when I try to execute a web page that use one of my 
Active X Component.
I will explain it! I had implemented an Active X that must to give the 
path of the windows directory, when I debugg my program using IExplorer, I 
go step by step, but when I use the conversion variables types 

"h_res=VarBstrFromUI2(*ptSis,mi_lcid,LOCALE_NOUSEROVERRIDE,us)"

being : LCID lcid;
        LPTSTR ptSis;
        BSTR * us;
I got an alert box tha said that an ecexption has being produced in the 
IEXPLORER.EXE(OLEAUT32.DLL): 0xC0000005: Access Violation 

How could I solve this problem? Thanks everybody for your time!!
