Re: [Dev-C++] conversion from void *(and is neither void nor pointer)

[Napoleon A. <nah...@so...>]

Hi there,

There solution to your problem can be found at http://www.relisoft.com/forum
check Windows API Programming in C++. Below is an excerpt of the discussions
that went on.

..... The hInstance member of _class is a HANDLE (that is, _class is a
WNDCLASSEX, and WNDCLASSEX's 'hInstance' member is a HANDLE, not, as one
might guess from it's name, an HINSTANCE).  mingw does define HANDLE as a
pointer to void.  But LoadImage is looking for an honest-to-god HINSTANCE.

There is also a solution on the forumwhich works fine on Dev-C++.
