Problem about the "shellexecute" difference between XP and Vista.   

Dear all,
I've got to write a program which should support windows unicode.
I use shellexecute to call the default "mailto" program, so that I can send 
mail with the default windows mail application.
The program runs well on XP.
But when we come to Vista, I can see various unrecognizable characters 
appear on my outlook.
When I debug into the program, the program runs write before the 
shellexecute call.
But after shellexecute is called, the characters I set as the title and 
content of my email come to a mess.
But when we use the same string on IE, the content in outlook seems right.
I wonder if anyone happens to know the cause of the problem.
If so, please help.
Thanks in advance for any further advice.

You'll need to show a code example that illustrates the problem you're
seeing.

Sorry for the inconvenience I caused.
In fact, my code is really simple.
ShellExecute(NULL, NULL, strMailTo, NULL, SW_SHOW);
I'm quite sure that on both XP and VISTA the strMailTo is of the right format.
But when outlook is activated if the strMailTo string is of the format 
"mailto:?subject=......", I alway get a mess in outlook on VISTA.
But it works fine on XP system.
Thanks for your attention.

Seeing as your problem is with odd characters in the URL string, it 
would be useful if you showed us what characters are in the URL string 
and how you generate them.
