Visual Studio C++ - Can't seem to add anything to basic window

[lostprophetpunk]

Heya there,

I recently scrapped Dev C++ for Visual C++ and have my basic window set up (see code #1 below). However...whenever I try to add in code (even to create a simple button) the build seems to fail every single time (see code #2).

Code #1 gives a clean compile with no errors.

Code #2 however gives a failed compile with these errors...

Lines 61 and 64, you forgot to capitalize the 'W' in your "hWnd" variable.

Thank you.

However there is one thing I am wondering...

How come the button appears in a win 98 style?

Add this line in one of your headers:
#pragma comment(linker,"\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")

Thank you for that. =]
