hello,

I am using ShellExecute to open a web browser with this function:

#include <windows.h>;


void google(string args)
{
    string URL ("http://www.google.com/search?q=");
    URL.append(args);

    ShellExecute(NULL, L"open", URL, NULL, NULL, SW_SHOWNORMAL);
}


</windows.h>

but I keep on getting the error message :
"error C2664: 'ShellExecuteW' : cannot convert parameter 3 from 'std::string' to 'LPCWSTR'"

does any one know how to change a string to a LPCWSTR or a way around this problem?

thanx

Solution 1

Convert to const char * first use .c_str(), then char * with static_cast if needed, and finally convert to LPCWSTR if necessary. You also might be able to change the type required by using Multi-Byte Character Set instead of Unicode, and that may modify the type you need to cast to.
