MessageBox Error

[Tomoko Kuroki]

I am getting these errors when I create a messagebox. The errors are below my messagebox code.

MessageBoxA(NULL, "it works", "works", 0);

Anyone know how to fix this?

It looks like you are using C++/CLI. Use the MessageBox Class instead of the Windows API.

My method for using MessageBox() is:

MessageBox(NULL, TEXT("Message Text"), TEXT("Caption"), MB_OK);

I let the compiler choose the version used, ANSI or Unicode, for both the MessageBox() function and the displayed text, depending on the character set used.

By the look of your error you are likely using the Unicode character set. MessageBoxA() is the ANSI version.

@integralfx

in C++/CLI it is called MessageBox::Show

Okay thanks. I used

MessageBox::Show("message", "title");

and it worked.
