BOOL ReadProcessMemory( HANDLE hProcess, PVOID pvAddressRemote, PVOID pvBufferLocal, DWORD dwSize, PDWORD pdwNumBytesRead);
參數(shù)
hProcess為遠程進程的句柄
pvAddressRemote用于指明遠程進程中的地址
pvBufferLocal是本地進程中的內(nèi)存地址
dwSize是需要傳送的字節(jié)數(shù)
pdwNumBytesRead和pdwNumBytesWritten用于指明實際傳送的字節(jié)數(shù).當函數(shù)返回時，可以查看這兩個參數(shù)的值.
ReadProcessMemory讀出數(shù)據(jù)，權(quán)限要大一些。下面這個打開進程的方式具備了查詢 讀和寫的權(quán)限
hProcess = OpenProcess(PROCESS_QUERY_INFORMATION Or PROCESS_VM_OPERATION Or PROCESS_VM_READ Or PROCESS_VM_WRITE, 0, ProcessId)
然后就要結(jié)合上面的程序來搜索了。只有當內(nèi)存是處于被占用狀態(tài)時才去讀取其中的內(nèi)容，而忽略空閑狀態(tài)的內(nèi)存。程序我就不在這兒寫了，和上面那段差不多。只是把dwTotalCommit = dwTotalCommit + mi.RegionSize換成了讀取內(nèi)存以及搜索這一塊內(nèi)存的函數(shù)而已。
1.通過FindWindow讀取窗體的句柄
2.通過GetWindowThreadProcessId讀取查找窗體句柄進程的PID值
3.用OpenProcess(PROCESS_QUERY_INFORMATION Or PROCESS_VM_OPERATION Or PROCESS_VM_READ Or PROCESS_VM_WRITE, 0, ProcessId)打開查到PID值的進程. 此打開具備 讀取,寫入,查詢的權(quán)限
4.ReadProcessMemory讀出指定的內(nèi)存地址數(shù)據(jù)
