ShellExecute

[Msm]

Hi all

I have stranger problem, ShellExecute is working on Vista but problem on XP.

ShellExecute( NULL, "open","http://www.abctest.com",NULL, "http://www.abctest.com", SW_SHOWDEFAULT);

or
ShellExecute( NULL, "open","http://www.abctest.com",NULL, "", SW_SHOW);

Both code working on only Vista.Can any one help me where i am wrong?

I have tested under Windows XP and both worked well.
However, anytime ShellExecute fails, you can see what's going wrong by taking a look at the error code (see return value in the ShellExecute function documentation.

May be in your XP there is no default browser set. So putting iexplore.exe and settings its parameter to desired site opens it in IE.

Could you very precisely define for whatpurpose you need an "any alternate option of shellexecute"?
Just to be able to open some internet browser which was not set as the default one and which name you don't know of?
Or something else?

Or you don't know what "default browser" mean?
Or you don't know how ShellExecute works?

Perhaps, you first must read MSDN about ShellExecute and Object Verbs

You seem to not!
Please, look at the post#4 (hypheni)
And then check in your XP machine whether key HKEY_CLASSES_ROOT\http\shell\open\command exists...
And the same - for HKEY_CLASSES_ROOT\mailto\shell\open\command

or simply set default browser from IE Tools > Programs

And hit Make Default button

You don't seem to understand the mechanism which ShellExecute uses to open data files. ShellExecute uses file associations to map file extensions to a program. For example, on most systems an extension of .txt maps to Notepad.exe.

Why this matters for your situation is because users can change or remove these extensions (which is probably why you are seeing failures on XP).
