类型“ const char *”的参数与类型“ LPCWSTR”的参数不兼容

Question

I have a very big problem... I' ve started today morning programming in Windows.h but I can't figure out why it gave me this problem as I litteraly copy the thing in the tut. ( https://youtu.be/8GCvZs55mEM?t=5m20s ) (I put the link to start the video when occurs my error)

The only thing I noticed is that in the tut it uses a LPCSTR variable for test, but my editor (Visual Studio Code) signal a LPCWSTR variable.

Sorry for the bad English.

#include <windows.h>

using namespace std;

int WINAPI WinMain (HINSTANCE hInts, HINSTANCE hPrevInst, LPSTR args, int ncmdshow)
{

MessageBox(NULL, "Ciao!", "La prima GUI", MB_OK, );

return 0;
}

How can I solve?

In the comment:

Now the error don't show up, thanks a lot. But there is a problem... The editor don' t built the application. The Console give:

Executing task: g++ -g main.cpp -o Program <  
main.cpp: In function 'int WinMain(void *, void *, char *, int)':
main.coo:8: pasing '__wchar_t *' as argument 2 of 'MessageBox(void *, const char *, const char *, UINT)'

Answer 1

Obviously not a good tutorial. Do it like like this

MessageBox(NULL, L"Ciao!", L"La prima GUI", MB_OK);

Using L changes the string literal so that it uses wide characters. A wide character string literal can be converted to the type LPCWSTR , a normal string literal cannot.
