How to launch an URL (like ShellExecute) but wait until finished? (not async)

Asked by Carl_Brody in Windows Programming, Windows XP Operating System

Tags: ,

I use the win32 ShellExecute function to launch programs, images (which are opened in my default image viewer), URLs (which are opened in the browser), etc.

Works fine, but the ShellExecute function returns immediately -- it doesn't wait until the executed item is finished.

When I want it to wait, I can use the spawnv( _P_WAIT , etc) function. But now I can't just parse images or URLs anymore: unlike ShellExecute, this function really expects an executable program name. So when opening URLs, I would have to determine the system's default program to launch http:// links with, similar with images, mp3 files, etc. Sounds like a lot of unnecessary hassle.

Is there a way to launch random items (not only programs), just like ShellExecute, but something that waits until the executed item is done?Start Free Trial

#include <windows.h>
#include <process.h>
 
char *program = "C:\\Windows\\Notepad.exe";
char *image = "C:\\Dog.jpg";
char *url = "http://www.disneyland.com/";
 
// Works fine, all 3 launched immediately:
int show = SW_SHOWNORMAL;
ShellExecute(NULL,NULL,program,NULL,NULL,show);
ShellExecute(NULL,NULL,image,NULL,NULL,show);
ShellExecute(NULL,NULL,url,NULL,NULL,show);
 
// First works fine: (and waits until notepad closes)
// The other 2 don't do anything :(
spawnv( _P_WAIT, program, NULL );
spawnv( _P_WAIT, image, NULL );
spawnv( _P_WAIT, url, NULL );
