How to convert string to LPWSTR in c++

Question

Can anyone help in converting string to LPWSTR

Now i wat to pass it as parameter for CreateProcessW(xx,command,x...)

But createProcessW() accepts only LPWSTR so i need to cast string to LPWSTR

Thanks in Advance

Answer 1

If you have an ANSI string, then have you considered calling CreateProcessA instead? If there is a specific reason you need to call CreateProcessW then you will need to convert the string. Try the MultiByteToWideChar function.

Another way:

mbstowcs_s

use with string.c_str(), you can find example here or here

OR

USES_CONVERSION_EX;

std::string text = "text";
LPWSTR lp = A2W_EX(text.c_str(), text.length());

OR

{
    std::string str = "String to LPWSTR";
    BSTR b = _com_util::ConvertStringToBSTR(str.c_str());
    LPWSTR lp = b;
    Use lp before SysFreeString...
    SysFreeString(b);
}
