åbne internet browser i cpp

Prøv:
ShellExecute(NULL, NULL, iexplore.exe, NULL, NULL, SW_SHOWNORMAL);

hmm det virker ikke er der nogen include filer der skal med ?????

#include<windows.h>

Spørgsmålet er hvilket miljø du koder i? Dos eller Windows?
Jeg antager det er windows, siden du nævner internet explorer.

Giv mig evt din kode...

alt det andet virker som det skal bare ikke dette

prøv at sætte "iexplore.exe"

takker det virker sender lige pointene

Svar.

Jeg tror at problemet med system("C:\\programmer\\internet explorer\\iexplore") er at der er mellemrum i filnavnet, så tror den at programmet hedder C:\programmer\internet og at explorer\iexplore er en parameter.

Problemet kan løses ved at putte "" omkring programnavnet:

system("\"C:\\programmer\\internet explorer\\iexplore\"");
