la naiba, l-am laut de aici

 irongeek.com|i.php?page=security|keylogger

e frumos ca e in c inteleg si eu ce se intampla.

de cand caut cum sa trimit mail din C.... de pe vremea cand imi facusem un alg care sub falsa imagine a unui benchmarker scria intr-un fis, pe langa rezultatul testelor si id si pass criptat din regisitri... pe vremea messen 7. eheh...

sper sa imi reuseasca compilarea... :?

hai ca esti tare!!!

pai sa vedem, daca ai stii ceva C ti-ai da seama singur, daca nu si chiar vrei sa te luminezi pune mana pe o carte de C++ de incepatori ( chiar si manuale de scoala , sunt mai usoare ) si invata... ( eu unu in a9-a stiam mare parte din ce era in manual) asa si ia-ti culegeri si fa exercitii ( culegerile mai au si probmele rezolvate care te ajuta ff mult ) si cand ajungi sa te obisnuiesti ff bine cu analogiile care se fac pt "traducerea" unui algoritm din situatie relea in cod... o sa fii mai luminat.

la sc nu inveti cine site ce, dar este BAZA.

intrebari de zone de cod daca ai poate pot sa te ajut sau poate te ajuta altii.

sau poti sa foloseti fuctii ale lui in alte prog facute de tine, ca exemplu sau chiar sursa de inspiratie

compilat direct la mine nu a mers... vad ca nu a fost nimeni curios sa-l incerce... unele chestii pe care nu am reusit sa le fac sa mearga in bc 50...

app. se poate ca alg sa stie cand useru e pe o fereasta anume... ma gandeam sa aiba o subfunctie care sa indentifice login-uri pe http... mess ??

am vazut intr-un exempli video un keyg care facea astea , dar nu era despre programare:(

app.2 ( a3-a editare) rog ajutor la partea cu trimisu email-lului... sunt un pic pe dinafara sau poate nu am avut prea multa rabdare...

alte metode de indentificat tastele?

in primul rand nu ai sa reusesti niciodata folosind gmail-ul cauta un smtp normal ....

ar trebui sa mearga numai ca trebuie sa iti faci un cont de mail acolo si sa configurezi corect smtp, user, parola etc. Se va comporta asemeni outlook-ului. Nu stiu, poate e mai greu de setat totul ca in outlook.

Daca senderul e pe erdeesh (nu stiu daca obligatoriu) se poate folosi chiar smtp.rdslink.ro Au trimis ei un mail recent dupa ce au blocat trimiterea mailurilor de pe compuri personale.

e interesant codu', problema mea e ca imi da eroare cand compilez la linkeditare (la functia de trimitere pe mail, in rest e ok) daca cineva a reusit sa il faca sa functioneze as fi recunoscator daca mi-ar zice cum a reusit sau cim l-a configurat (smtp, port etc) sau o alta modalitate de trimitere. m-am mai gandit si la un fiser .bat care sa fie apelat de fctia system() si acesta sa trimita, dar nu e cea mai eleganta profesionista metoda.

Idei??? Mersi.
