求助 VC++中使用OCX
VC++中执行外部程序，将一个.exe外部程序的扩展名改为.ocx后，在VC++中执行这个.ocx程序
[解决办法]
创建进程就完了呗

SECURITY_ATTRIBUTES sa;     
HANDLE hRead, hWrite;     

sa.nLength = sizeof(SECURITY_ATTRIBUTES);     
sa.lpSecurityDescriptor = NULL;     
sa.bInheritHandle = TRUE;     
if (!CreatePipe(&hRead,&hWrite,&sa,0))       
{     
return   FALSE;     
}       

STARTUPINFOA si;     
PROCESS_INFORMATION pi;       
si.cb = sizeof(STARTUPINFOA);     
GetStartupInfoA(&si);       
si.hStdError= hWrite;     
si.hStdOutput= hWrite;     
si.wShowWindow= SW_HIDE;     
si.dwFlags= STARTF_USESHOWWINDOW 
[解决办法]
 STARTF_USESTDHANDLES;     
//关键步骤，CreateProcess函数参数意义请查阅MSDN
        char *CommandLine = "start C:\\My.ocx";//使用DOS命令行启动一个程序  
if   (!CreateProcessA(NULL, CommandLine, NULL,NULL,TRUE,NULL,NULL,NULL,&si,&pi))       
{     
return FALSE;     
}

CloseHandle(hWrite);    
CloseHandle(hRead);

::WaitForSingleObject(pi.hProcess, INFINITE);
