我是新手C ++编码员。我一直在尝试从互联网教程中编译自己的DLL Injector。
这是我的代码：
#include <windows.h>
#include <tlhelp32.h>
#include <shlwapi.h>
#include <conio.h>
#include <stdio.h>
#include <iostream>
#define WIN32_LEAN_AND_MEAN
#define CREATE_THREAD_ACCESS (PROCESS_CREATE_THREAD | PROCESS_QUERY_INFORMATION | PROCESS_VM_OPERATION | PROCESS_VM_WRITE | PROCESS_VM_READ)
BOOL Inject(DWORD pID, const char * DLL_NAME);
DWORD GetTargetThreadIDFromProcName(const char * ProcName);
using namespace std;
int main(int argc, char * argv[])
{
// The name of the process you want to inject
DWORD pID = GetTargetThreadIDFromProcName("notepad.exe");
// Get the dll's full path name
char buf[MAX_PATH] = {0};
GetFullPathName("Project1.dll", MAX_PATH, buf, NULL); // On the place where is Project1.dll you can put the name of your dll
printf(buf);
printf("\n");
// Inject our main dll
if(!Inject(pID, buf))
{
printf("Not loaded!"); // If injection is not sucsessfull
}
else
{
printf("Loaded!"); // If injection is sucsessfull
}
_getch();
return 0;
}
BOOL Inject(DWORD pID, const char * DLL_NAME)
{
HANDLE Proc;
HMODULE hLib;
char buf[50] = {0};
LPVOID RemoteString, LoadLibAddy;
if(!pID)
return false;
Proc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pID);
if(!Proc)
{
sprintf(buf, "OpenProcess() failed: %d", GetLastError());
//MessageBox(NULL, buf, "Loader", MB_OK);
printf(buf);
return false;
}
LoadLibAddy = (LPVOID)GetProcAddress(GetModuleHandle("kernel32.dll"), "LoadLibraryA");
// Allocate space in the process for our DLL
RemoteString = (LPVOID)VirtualAllocEx(Proc, NULL, strlen(DLL_NAME), MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE);
// Write the string name of our DLL in the memory allocated
WriteProcessMemory(Proc, (LPVOID)RemoteString, DLL_NAME, strlen(DLL_NAME), NULL);
// Load our <strong class="highlight">DLL</strong>
CreateRemoteThread(Proc, NULL, NULL, (LPTHREAD_START_ROUTINE)LoadLibAddy, (LPVOID)RemoteString, NULL, NULL);
CloseHandle(Proc);
return true;
}
DWORD GetTargetThreadIDFromProcName(const char * ProcName)
{
PROCESSENTRY32 pe;
HANDLE thSnapShot;
BOOL retval, ProcFound = false;
thSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if(thSnapShot == INVALID_HANDLE_VALUE)
{
//MessageBox(NULL, "Error: Unable to create toolhelp snapshot!", "2MLoader", MB_OK);
printf("Error: Unable to create toolhelp snapshot!");
return false;
}
pe.dwSize = sizeof(PROCESSENTRY32);
retval = Process32First(thSnapShot, &pe);
while(retval)
{
if(StrStrI(pe.szExeFile, ProcName))
{
return pe.th32ProcessID;
}
retval = Process32Next(thSnapShot, &pe);
}
return 0;
}
我一直收到错误：
“1＆gt; Injector.obj：错误LNK2019：未解析的外部符号__imp__StrStrIA @ 8在函数”unsigned long __cdecl GetTargetThreadIDFromProcName（char const *）“中引用（？GetTargetThreadIDFromProcName @@ YAKPBD @ Z）
1＆gt; C：\ Users \ Rizker \ documents \ visual studio 2010 \ Projects \ Injector \ Debug \ Injector.exe：致命错误LNK1120：1个未解析的外部“
感谢任何帮助。哦，是的，这段代码在我格式化我的电脑之前曾经工作过，但在那之后，我认为这种方式有所破坏。
