char cmd[40];
driver = FuncGetDrive(driver);
sprintf_s(cmd, "%c:\\test.exe", driver);
I cannot use cmd
in
sei.lpFile = cmad;
so,
how to convert char
array to wchar_t
array ?
Just use this:
static wchar_t* charToWChar(const char* text)
{
const size_t size = strlen(text) + 1;
wchar_t* wText = new wchar_t[size];
mbstowcs(wText, text, size);
return wText;
}
Don't forget to call delete [] wCharPtr
on the return result when you're done, otherwise this is a memory leak waiting to happen if you keep calling this without clean-up. Or use a smart pointer like the below commenter suggests.
Or use standard strings, like as follows:
#include <cstdlib>
#include <cstring>
#include <string>
static std::wstring charToWString(const char* text)
{
const size_t size = std::strlen(text);
std::wstring wstr;
if (size > 0) {
wstr.resize(size);
std::mbstowcs(&wstr[0], text, size);
}
return wstr;
}
From MSDN:
#include <iostream>
#include <stdlib.h>
#include <string>
using namespace std;
using namespace System;
int main()
{
char *orig = "Hello, World!";
cout << orig << " (char *)" << endl;
// Convert to a wchar_t*
size_t origsize = strlen(orig) + 1;
const size_t newsize = 100;
size_t convertedChars = 0;
wchar_t wcstring[newsize];
mbstowcs_s(&convertedChars, wcstring, origsize, orig, _TRUNCATE);
wcscat_s(wcstring, L" (wchar_t *)");
wcout << wcstring << endl;
}
