你的C/C++ 程序可以使用TalkCentrex 控件启动跟其它人的 对话，下面是代码：
#include <ole2.h>
void TalkCentrex_command( BSTR cmd )
{
const GUID CLSID_TalkCentrex = {0xE59FA478, 0x0535, 0x43E6,{ 0xBE,
0x12, 0x1D, 0x6E, 0x75, 0x51, 0x2C, 0x3B} };
HRESULT hr;
IDispatch* pIDispatch ;
DISPID dispid ;
OLECHAR* func =
L"command";
DISPPARAMS funcparams ;
VARIANTARG vcmd ;
vcmd.vt = VT_BSTR;
vcmd.bstrVal = cmd;
funcparams.rgvarg
= &vcmd;
funcparams.cArgs = 1;
funcparams.cNamedArgs =
0;
hr = ::CoInitialize( NULL );
if( FAILED( hr ) )
return ;
hr = ::CoCreateInstance( CLSID_TalkCentrex, NULL,
CLSCTX_INPROC_SERVER, IID_IDispatch, (void**)&pIDispatch ) ;
if( FAILED( hr ) ) return ;
hr = pIDispatch->GetIDsOfNames(IID_NULL,
&func, 1, LOCALE_SYSTEM_DEFAULT, &dispid ) ;
// if( FAILED( hr
) ) return ;
hr = pIDispatch->Invoke(dispid, IID_NULL,
LOCALE_SYSTEM_DEFAULT, DISPATCH_METHOD, &funcparams, NULL, NULL,
NULL) ;
pIDispatch -> Release();
} |
调用这个函数的例程: ( 启动跟 VAVAA : 800830xxxxx 的 对话)
BSTR cmd( L" ?800830xxxxx" );
TalkCentrex_command( cmd ) ; |
