VC调用外部EXE程序的问题，高手清进...

[florida1227]

我使用vc调用oracle的数据导入工具sqlldr,但调用的时候总会出现dos命令行窗口，一晃而过，有什么办法消除这窗口出现？
调用程序如下：
sprintf(Execommand, "sqlldr.exe userid=%s/%s@%s control=%s",User, Pwd, Server, CtlFile);
if (system(Execommand) == -1)
{
*nProcessed = 0;
}
else
{
*nProcessed = 1;
}

没试过，CreateProcess行吗？

CreateProcess等，设置SW_HIDE隐藏窗口

[HoneyPot]

WinExec("drsmart.exe",SW_HIDE);

一般用CreateProcess，它还可以控制执行环境

STARTUPINFO start;
memset(&start,0,sizeof(start));
start.cb = sizeof(start);
start.wShowWindow = SW_HIDE;
start.dwFlags = STARTF_USESHOWWINDOW;

if( !CreateProcess( NULL,
"Mdrsmart.exe",
NULL,
NULL,
FALSE,
0,
NULL,
NULL,
&si,
&pi )
)
{
ErrorExit( "CreateProcess failed." );
}

// Wait until child process exits.
WaitForSingleObject( pi.hProcess, INFINITE );
