Nick_huangZ adalah besar, bolehkah anda beritahu saya bagaimana anda boleh memodifikasi untuk mendapatkan keuntungan positif, yang telah banyak kerugian dalam pemindaian semula?
Nick_huangAdakah anda boleh menjelaskan logiknya dengan mudah? dan bagaimana anda boleh mengubahnya untuk mendapatkan hasil yang positif? saya cuba parameter dan data lalai, dan saya kehilangan banyak.
banelenZ bos, lihat kod GetCommand di sini, saya tidak faham, tidak ada penerangan API, bolehkah anda mengelirukan saya?
kreatPonsel analog memastikan pembelian dan penjualan tidak terganggu, tetapi peranti sebenar yang sering membeli dan menjual tidak semestinya dipasang.
HaixiongleeMengapa data yang diulas semula adalah baik, tetapi operasi cakera sebenar tidak berguna?
banelenTerima kasih, saya jumpa.
