ejem. Si lo tienes en vb, es facilmente convertible a .net (sea vb.net o C#), si sabes y usas un poquito de logica, lo sacas en seguida. Total, en vb.net un 90% del codigo seguira intacto ^^

EDIT: Para usar las APIs, busca la declaracion en www.pInvoke.net

[XSaMuXPH *-* Traigo uno encima! =D!]

Ops! error, pInvoke.net VS 2003-2005, yo uso 2008 

[raul338]

jeje...dije busca la declaracion, no es necesario el plugin. Igual funciona en el 2008 (no te fijaste bien, tiene una version para el 2008 o capaz es la misma) pero junto con el plugin te viene otra de sus utilidades pero en version de prueba. yo no lo tengo instalado, solo usa el buscador: pones el nombre de la api o la dll y te sale una lista de las declaraciones en C#, vb.net (no todas, pero son convertibles) y la clasica vb6

como te atreves a decir eso.....


El framework te cambia radiclamente todo, que puedas hacer lo mismo de antes de forma parecida es algo muy diferente, pero hasta la administracion de memoria es toalemente diferente en .net, lo que debes hacer es  er que clases son las que te sirven para las tareas en vez de usar la APIS, ese es el objetivo del framewrok.

Ejem, me referi a que el codigo quedaria intacto, ovbiamente cambia radicalmente todo, pero el codigo se mantiene practicamente parecido (ni hablar de MSIL  ahi si te creo que cambia todo)
Que yo sepa, .net no tiene clases para manejar la memoria con "libre albedrio" 

[XSaMuXPH *-* Traigo uno encima! =D!]

Listo!, lo logre , en mi siguiente post posteare el code tal vez sea de utilidad para muchos  .

[‭‭‭‭jackl007]

como funciona?
lo compile en C++, y todo normal, lo ejecuto por consola y no muestra nada ni hace nada...
abro el notepad y todo normal...

entonces que hace? no inyecta nada ni codigo

Compilialo en consola de C++, antes abre el block de notas y luego veras que aparecera un mensaje, esto no es inyeccion dll esto es inyeccion dll sin dll osea inyecta un messagebox como si fuese el la dll, a mi me funciona.

salu2 a todoz bueno tengo una pequeña duda con respecto a este scritp... yo recien estoy aprendiendo a utilizar el VB 0.6 me he propuesto la meta de aprenderlo solo estudiando de los foros nada de profes -.-" pero al verme topado con esta pregunta.. quisiera pedir ayuda a uds que dominan mas del tema.. estoy usando el scritp de arriba llego a crear mi proyecto.. denominado [inyector xD].. llega a inyectar la *.dll que quiero al programa*.exe que quiero .. pero aqui viene mi duda... al scanear mi [inyector xD].exe en virustotal.com me detecta un virus o algo asi T_T quisiera saber xq ocurre eso o como hago para quitarle ese troyano o virus al programa que he creado y en que momento le meti ese virus o.O" ? ploop!!! aver si alguien me da alguna respuesta T_T grax de antemando
chaito ...!!
