If you assign a value to a cstring directly, such as cstring STR = "char", or directly enter "char" in the function parameter, or assign a value to a string, the preceding error occurs. You can solve this problem using either of the following methods:

1. Add text before the content (invalid variable), such as MessageBox (hwnd, szchar, text ("char"), 0 );------


UNICODE: converts all strings to text ("") or _ T ("")
For example,


ABC. lpszclassname = "fb2009"; should be changed


ABC. lpszclassname = _ T ("fb2009 ");


To do this, you also need to include the tchar. h header file.


2. In Project Properties> General, change the uicode to multi-character segments.
