Visual C++:error C2664: 'GetModuleFileNameW' : cannot convert parameter 2 from 'char' to 'LPWCH'

A lot of the "functions" of the Windows API are actually macroes to either the ANSI (

A

) or Unicode (

W

for wide) version of the function. Depending on your project settings, these macroes will
be either

DoSomeFunctionA

or

DoSomeFunctionW

when you want to call

DoSomeFunction

. The portable way would be then to use

TCHAR

because it is defined as

char

for ANSI and

wchar_t

for Unicode.

If you don't want to compile with Unicode, you can change your project settings to

Project Properties -> Configuration Properties -> General -> Character Set -> Use Multibyte Character
Set

.

If you do want to compile with Unicode, then you should append an

A

(ex:

GetModuleFileNameA

) to the necessary function names.
