最近在測試_poepn指令於BCB6 & win7(winXP) 環境下, 無法正確取得FILE Handle, 

都是得到NULL, 想請問哪個環節我忽略了?

[code cpp]
void __fastcall TForm1::Button1Click(TObject *Sender)
{
char psBuffer[128];
FILE *chkdsk;
if( (chkdsk = _popen( "dir *.*", "r" )) == NULL )
ShowMessage("_popen failed");

}
[/code]

這function是不是只能在console模式下使用壓^^?

感謝taishyang提醒, 果然用console專案就可以執行, 謝謝

另外附帶一提, 我本來是想在BCB6環境下呼叫gnuplot C API繪圖,

看來現在得透過額外呼叫console程式來繪圖了!
