WCHAR* not compatible with "LPSTR" parameter. In wsprintf C++ - visual-c++

Question

Can't compile the following code in C++ with Visual Studio 2017 (Got it from: Source Code):
#include <Wincodec.h> // we use WIC for saving images
#include <d3d9.h> // DirectX 9 header
#pragma comment(lib, "d3d9.lib") // link to DirectX 9 library
#include <stdio.h>

#include <wchar.h>

int _tmain(int argc, _TCHAR* argv[])
{

}
Gives error at:
// save all screenshots
for (UINT i = 0; i < count; i++)
{
WCHAR file[100];
wsprintf(file, L"cap%i.png", i);
HRCHECK(SavePixelsToFile32bppPBGRA(mode.Width, mode.Height, pitch, shots[i], file, GUID_ContainerFormatPng));
}
Where:
"WCHAR file[100]" is not compatible with "LSPTR" on wsprintf.
L"cap%i.png" (const wchar_t) is not compatible with LPCSTR on wsprintf.
And in:
int _tmain(int argc, _TCHAR* argv[])
{
HRESULT hr = Direct3D9TakeScreenshots(D3DADAPTER_DEFAULT, 10);
return 0;
}
Where _TCHAR is not defined.
¡I'm new to C++ so please give me some hints!
