求助各位大神，為什么會寫入失敗，編譯沒有問題，但是運行起來會提示寫入路徑名失敗

Check一下WriteProcessMemory函式的回傳值，如果失敗，GetLastError()的值是多少？uj5u.com熱心網友回復：
AddressDW = (LPDWORD)VirtualAllocEx(hProcess, NULL, 256, MEM_COMMIT, PAGE_READONLY);PAGE_READONLY你寫得進去才怪了,換成PAGE_READWRITE

額。。。好的，回家以后試一下，多謝大佬轉載請註明出處，本文鏈接：https://www.uj5u.com/gongcheng/38767.html
