遠端載入與解除安裝DLL

dword getprocessidbyname(lpctstr szprocess)//注意要加exe字尾

} while (process32next(hsnapshot,&pe32));
closehandle(hsnapshot);
return dwret;
}

bool inject(lpctstr szmodule, dword dwid)

int cbyte  = (_tcslen(szmodule)+1) * sizeof(tchar);
lpvoid paddr = virtualallocex(hprocess, null, cbyte, mem_commit, page_readwrite);
if ( !paddr || !writeprocessmemory(hprocess, paddr, szmodule, cbyte, null)) 
#ifdef _unicode
pthread_start_routine pfnstartaddr = (pthread_start_routine)getprocaddress(getmodulehandle(_t("kernel32")), "loadlibraryw");
#else
pthread_start_routine pfnstartaddr = (pthread_start_routine)getprocaddress(getmodulehandle(_t("kernel32")), "loadlibrarya");
#endif
總是被對映到相同的位址
if ( !pfnstartaddr ) 
dword dwthreadid = 0;
handle hremotethread = createremotethread(hprocess, null, 0, pfnstartaddr, paddr, 0, &dwthreadid);
if ( !hremotethread ) 
waitforsingleobject(hremotethread,infinite);
virtualfreeex(hprocess,paddr,cbyte,mem_commit);
closehandle(hremotethread);
closehandle(hprocess);
return true;
}

簡單提權函式

bool enableprivilege(lpctstr lpszprivilegename, bool benable)

bool unloaddll(lpctstr szdllname, dword dwid)//要解除安裝的dll名，程序pid

int cbyte  = (_tcslen(szdllname)+1) * sizeof(tchar);
lpvoid paddr = virtualallocex(hprocess, null, cbyte, mem_commit, page_readwrite);
if ( !paddr || !writeprocessmemory(hprocess, paddr, szdllname, cbyte, null)) 
#ifdef _unicode
pthread_start_routine pfnstartaddr = (pthread_start_routine)getmodulehandlew;
#else
pthread_start_routine pfnstartaddr = (pthread_start_routine)getmodulehandlea;
#endif
總是被對映到相同的位址
if ( !pfnstartaddr ) 
dword dwthreadid = 0,dwfreeid=0,dwhandle;
handle hremotethread = createremotethread(hprocess, null, 0, pfnstartaddr, paddr, 0, &dwthreadid);
if ( !hremotethread ) 
waitforsingleobject(hremotethread,infinite);
// 獲得getmodulehandle的返回值
getexitcodethread(hremotethread,&dwhandle);
closehandle(hremotethread);
// 使目標程序呼叫freelibrary，解除安裝dll
#ifdef _unicode
pthread_start_routine pfnfreeaddr = (pthread_start_routine)freelibrary;
#else
pthread_start_routine pfnfreeaddr = (pthread_start_routine)freelibrary;
#endif
handle hfreethread = createremotethread(hprocess, null, 0, pfnfreeaddr,(lpvoid)dwhandle,0,&dwfreeid);
if ( !hfreethread ) 
waitforsingleobject(hfreethread,infinite);
virtualfreeex(hprocess,paddr,cbyte,mem_commit);
closehandle(hfreethread);	
closehandle(hprocess);
return true;
}

C 動態載入解除安裝 DLL

我最近做的軟體，需要檢測dll或exe是否混淆，需要反射獲得類名，這時發現，c 可以載入dll，但不能解除安裝dll。於是在網上找到乙個方法，可以動態載入dll，不使用時可以解除安裝。我在寫乙個wpf 程式，發現可以通過assembly.load載入 dll，但是如何解除安裝dll？下面就來說下如何...
