lo q necesito es darle paramatros al programa pero no caxo como ???

[Gallu]

Para recibir parametros en el programa utilizas los que recibe el main

Código (c) [Seleccionar] Expandir


int main (int argc, char *argv[]) {


de echo aquí lo estás usando , deduzco que te has copiado este código de algún sitio

Código (c) [Seleccionar] Expandir


CreateChildProcess (argv[1]);


[_alexis_]

si pero no le pasa ningun parametro

[Gallu]

si pero no le pasa ningun parametro

Explicate mejor , te he dicho como recibir los parámetros en el programa , para pasarselos lo haces escribiendo  nombre_programa.exe param1 param2 , etc....
