hi i coded a hook dll,but when i wanna add a file and write the result i dont know what happens.my file is wrong or somtimes it's empty (but messagebos shows the right result !!!!!!!) here is my code: #include "a.h" #include #include #include #include #include #include #include #include #include #include #include #include int x=0; int stream; FILE* fout; static BOOL bHooked = FALSE; static HHOOK CBT=0,CBT1=0; static HINSTANCE hInst; static int count; char szModName[1024]; char szModName1[1024]; char nul[1024]; char win[1024]; void GetWinDir(void); LRESULT CALLBACK CBTProc(int code, WPARAM wParam, LPARAM lParam); //LRESULT CALLBACK CBTProc1(int code, WPARAM wParam, LPARAM lParam); BOOL WINAPI DllMain(HINSTANCE hinstDLL,DWORD fdwReason, LPVOID lpvReserved) { switch (fdwReason) { case DLL_PROCESS_ATTACH: hInst=hinstDLL; count=0; break; case DLL_THREAD_ATTACH: break; case DLL_THREAD_DETACH: break; case DLL_PROCESS_DETACH: break; default: break; } return TRUE; } DLL_EXPORT void BagaHooku(void) { if(!bHooked) { CBT = SetWindowsHookEx(WH_CBT, (HOOKPROC)CBTProc, hInst, (DWORD)NULL); /// CBT1 = SetWindowsHookEx(WH_CBT, (HOOKPROC)CBTProc1, hInst, (DWORD)NULL); bHooked = TRUE; } } DLL_EXPORT void ScoateHooku(void) { if(bHooked) { UnhookWindowsHookEx(CBT); // UnhookWindowsHookEx(CBT1); } } LRESULT CALLBACK CBTProc(int nCode,WPARAM wParam,LPARAM lParam) { if ((nCode==HCBT_ACTIVATE)||(nCode==HCBT_SYSCOMMAND)||(nCode==HCBT_QS)||(nCode==HCBT_CREATEWND)) //if (nCode==HCBT_DESTROYWND) { //MessageBox (NULL, TEXT ("send processes"), TEXT ("HelloMsg"), 0) ; HANDLE hProc; HMODULE hMods[1024]; DWORD n; DWORD dwProcessId ; DWORD lpExitCode; DWORD dwSize,dwType,dwDisp; HKEY Regentry; char *host1; char host[1024]; char rezerva[1024]; //MessageBox (NULL, TEXT ("send processes"), TEXT ("HelloMsg"), 0) ; GetWindowThreadProcessId((HWND)wParam, &dwProcessId); hProc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, (DWORD)dwProcessId); if(EnumProcessModules(hProc, hMods, sizeof(hMods), &n)) { if (n>0) GetModuleFileNameEx(hProc, hMods[0], szModName, sizeof(szModName)); } GetExitCodeProcess(hProc,&lpExitCode); if(!(host1=strrchr(szModName,'\\'))) strcpy(host,szModName); else strcpy(host,host1

You'd get a lot more help if you'd narrow this down to just a handful of lines. No one likes to wade through complete programs, or even several pages of code, to locate a problem. Try:

void main( void )
{
char host[1024], szModName[1024], *host1; // initialize these accordingly

if (! (host1 = strrchr(szModName, '\\\\')))
    strcpy(host, szModName);
else
    strcpy(host, host1 + 1);

FILE \*fout = fopen("out.txt", "a+");
fwrite(host, 1, strlen(host), fout);
fclose(fout); 

}

Now step through each of these until you locate the offending statement.

are you sure you are looking at the correct out.txt file? because this code looks fine: (isolated that is) fout = fopen("out.txt", "a+"); fwrite(host, 1,strlen(host), fout); fclose(fout); Is this a Unicode project? AliR. Visual C++ MVP
