Error c2065: "pcontext": Undeclared Identifier-problem resolved

At first I wrote only one line:

 

# Include <windef. h>

 

The following error occurs during compilation:

 

1> C:/program files/Microsoft sdks/Windows/v6.0a/include/winnt. H (5547): Error c2146: syntax error: Missing ";" (before the identifier "contextrecord") <br/> 1> C: /program files/Microsoft sdks/Windows/v6.0a/include/winnt.

Then I searched for information on the Internet and found that I changed # include <windef. h> to # include <windows. h>. No error was reported during program compilation.
