Grax a tdos, voy ver si lo consigo y ya os digo 

En el code de ░▒▓BlackZeroҖ▓▒░ me da error nada mas arrancar:

Código [Seleccionar] Expandir

nBytes = Len(CodigoHex) \ 2
"Procedimiento externo no es válido (CodigoHex)"

Lo he arreglado ojala y te sirva

Mi pregunta es como puedo pasarlo a hexadecimal, y posteriormente (nose como..:S) poder pasarlo a letras normales para cargarlo al text...

el que pide que le realicen la tarea y despues nos llame engreidos es un idiota pero bue ni que asi son:

Nike42:

Ahora ese que pides o del multiline o como los textbox seria midiendo el ancho del caracter pero antes medir el anchoo del rectangulo y dividirlo entre el ancho de el caracter para asi determinar cuando se deberia de realizar un salto de linea algo asi ve:

Código [Seleccionar] Expandir


Ancho digamos del picture (representado por la linea de abajo):

|------------------------------|

Ancho = DeLaLinea

despues usas la funcion:

AnchoTextual = picture1.Textwidth("Aca el texto")

Si anchotextual>=ancho entonces
   salta a la siguiente linea
de lo contrario
   sigue en la linea


lo pongo asi por que la verdad debes pensar un poco eso de multiline es algo facil colo usa la concatenacion con el texto actual con  VBNewLine o chr$(13)

con respecto al proyecto en general, queria saber si despues que se hace el drawtext o el paint picture no hay forma de volver hacia atras, osea deshacer lo hecho o ya queda grabado en la imagen.

bueno eso ya es a tu ingenio ya que despues de dibujar en un picture me parece que no se desase pero eso tiene arreglo solo ingeniatelas a mi se me ocurre cargar la imagen x en dos picture

uno visible y uno no visible y si dese desaser un cambio en el picture2 (el que no se ve) qeu guarde la imagen original y despues por medio de variables se guarden los hechos que se puedan desaser y segun estos cortar X trozos de la imagen del picture2 al picture1 y hacer los cambios...

algo loco pero resultante

P.D. a mi se me ocurrio esto ati se te puede ingeniar otra cosa mas facil (la que mendiona usaria matrices de variables en las que se guardar informacion de X puntos de restauracion de los cambiso de la imagen algo asi como en Paint)

baje el tuto pero me pide una contraseña

Wenas, quisiera q me dieran alguna recomendacion (y a ser posible un pequeño ejemplo) acerca de un joiner q pueda mezclar archivos tipo avi, ya q no he encontrado nada de lo q servirme..

muxas gracias y un saludo

esto me parece SPAM usa el Boton   Buscar

webbrowser a segun yo se muentras el webbrowser este oculto no se puede trabajar con este o no se si lo que quieres es mandar un click a un boton de algun programa usa EnumChildWindows en un Webbroser leete algunos post atras que esta la respuesta al parecer

creo que obteniendo el hwnd del elemento al que haces click y enviandole el mensjae WM_CLICK puedes hacerlo

Obtener el Hwnd es enlistando las subventanas del programa pasate a ver un post mio anterior (espero y esa forma funcione con lo que buscas): <click>

HDC a Picture

con respecto a los PNG seria cargarlo a el modulo y despues transformarlo a pictura o bitmap  ve esta funcion sacada de la Api-Guide

la funcion en si transforma de un Hdc a Picture ok' [como ejemplo poongo este codigo completo de la Api-Guide]
