Showing multiple web pages with ShellExecute

[sundayCoder]

Hello,
I have question conserning ShellExecute.

I have function like this:

void OpenURL(LPWSTR url) {
//Notice! 6 parameters, not 7
ShellExecute(NULL, L"open", url, NULL, NULL, NULL);
}

If I then use this function like this:

OpenURL(L"http://www.google.com/");
OpenURL(L"http://bytes.com/");
OpenURL(L"http://www.yahoo.com/");

sometimes only the first web page is opened, but sometimes all of them. Could someone enlighten me what I should do so that all the web pages opened with OpenURL-function are always opened? Also, better ways to open web pages are very welcome. I use Visual Studio 2008 Express and Visual Studio 2013 Express.

I notice you are using wide strings: L"etc...".

A wide string is not an LPWSTR. I suggest a call to MultiByteToWide Char to correctly translate and ASCII string into an LPWSTR.

Let me know if this fixes your problem.

Thanks for the reply! It's been about 10 years since my previous c++ coding, so I'm kind of a beginner again (I had only experience in ANSI c++).

My best try to use MultiByteToWide Char took me in situation where the compiler informed that "cannot convert parameter 1 from 'std::wstring' to 'LPWSTR'". So I need little more help with using MultiByteToWide Char (this is my first time using it).

Could I have little sample code of converting ANSI string into an LPWSTR with MultiByteToWide Char?

Thanks for the link! I got the conversion working now.

At least so far it seems that the problem I described in my first post is gone, all the web pages I have tried to open with OpenURL-function have always been opened.

So it seems that the problem occured because of wrong data types. Thanks! I learned new useful things.
