whats the debug privileges? In youtube tutorial is used win xp but i hav win 7, would that be a problem? if i debug variables to console i will probably get just some numbers that doesn't say any thing for me but, I will try it. edit1: why doesn't this exe run on win xp?( copied binary (didn't recompile it)) "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem" in win 7 it runs but doen't inject.

I got DLL injection example from youtube. http://www.youtube.com/watch?v=H3O3hmXkt1I For some reason it says: "Injection failed" (under indows 7) and under win xp this exe doesn't even start (i see msgbox telling me to reinstall this app). It compiles w/o errors Injector.exe #include <iostream> #include <direct.h> #include <windows.h> #include <tlhelp32.h> using namespace std; char* GetCurrentDir() { char* szRet = (char*)malloc(MAX_PATH); _getcwd(szRet, MAX_PATH); return szRet; } LPCTSTR SzToLPCTSTR(char* szString) { LPTSTR lpszRet; size_t size = strlen(szString)+1; lpszRet = (LPTSTR)malloc(MAX_PATH); mbstowcs_s(NULL,lpszRet,size,szString,_TRUNCATE); return lpszRet; } void WaitForProcessToAppear(LPCTSTR lpcszProc, DWORD dwDelay) { HANDLE hSnap; PROCESSENTRY32 peProc; BOOL bAppeared = FALSE; while (!bAppeared) { if((hSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0)) != INVALID_HANDLE_VALUE) { peProc.dwSize = sizeof(PROCESSENTRY32); if(Process32First(hSnap, &peProc)) while(Process32Next (hSnap, &peProc) && !bAppeared) if(!lstrcmp(lpcszProc, peProc.szExeFile)) bAppeared = TRUE; } CloseHandle(hSnap); Sleep(dwDelay); } } DWORD GetProcessIdByName(LPCTSTR lpcszProc) { HANDLE hSnap; PROCESSENTRY32 peProc; DWORD dwRet = -1; if((hSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0)) != INVALID_HANDLE_VALUE) { peProc.dwSize = sizeof(PROCESSENTRY32); if(Process32First(hSnap, &peProc)) while(Process32Next (hSnap, &peProc)) if(!lstrcmp(lpcszProc, peProc.szExeFile)) dwRet = peProc.th32ProcessID; } CloseHandle(hSnap); return dwRet; } BOOL InjectDLL(DWORD dwPid, char* szDllPath) { DWORD dwMemSize; HANDLE hProc; LPVOID lpRemoteMem, lpLoadLibrary; BOOL bRet = FALSE; if((hProc = OpenProcess(PROCESS_VM_OPERATION | PROCESS_VM_WRITE | PROCESS_CREATE_THREAD, FALSE, dwPid)) != NULL) { dwMemSize = strlen(szDllPath) +1; if((lpRemoteMem = VirtualAllocEx(hProc,NULL,dwMemSize,MEM_COMMIT,PAGE_READWRITE)) != NULL) if(WriteProcessMemory(hProc, lpRemoteMem, (LPCVOID)szDllPath,dwMemSize,NULL)) { lpLoadLibrary = GetProcAddress(GetModuleHandleA("kernel32.dll"), "LoadLibraryA"); if(CreateRemoteThread(hProc, NULL, 0, (LPTHREAD_START_ROUTINE)lpLoadLibrary, lpRemoteMem, 0, NULL) != NULL) bRet = TRUE; } } CloseHandle(hProc); return bRet; } int main() { char szProc[MAX_PATH],szD

Great code, but I have 1 problem (I used Code::Blocks to compile) C:\Documents and Settings\rain\My Documents\fail.o:fail.cpp:(.text+0x96)||undefined reference to `_GetStockObject@4'| ||=== Build finished: 1 errors, 0 warnings ===| I tried this manually but it didn't work (I use win xp pro). Is there any solutions that works like lockig icons works in linux? I have seen linux desktops which are made so if you lock icons then u cant move them, icons just won't come with ur mouse, can I do this kond locking in windows too?

How to write C or C++ program that locks desktop icons placement? I have googled around it and all I found were commercial software or closed source software. Any hints are welcome. thanks!
