[Dev-C++] No matching Function Error

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

[windows 2000, DevCpp (mingw)]C++ in Action Windows project after script =
9.
--------------------------------------------------------------------
Hello,
I'm working my way through C++ in Action. And I'm stuck with the error =
message:

C:\Projects\Winnie\Class.cpp
In method `void Win::ClassMaker::SetIcons(int)':
23 C:\Projects\Winnie\Class.cpp
no matching function for call to `StdIcon::Load (void *&, int &)'
43 C:\Projects\Winnie\Icon.h
candidates are: void StdIcon::Load(HINSTANCE__ *, int)

I have gone through the files Icon.h, Icon.cpp and the functions are all =
there. Icon.h has also been included in Class.cpp. What could be wrong. =
For the record I have all the project files in one directory. I have =
linker errors when I split them into differnt directories.

I'll appreciate your help please.

Napoleon.

When you place a file in a different directory, say "icon_class", you have
to update the #include directive correspondingly. For example, if it was

    #include "icon.h"

when `icon.h' is in the same directory, then, if you move it to
`icon_class', it would become:

    #include "icon_class/icon.h"

This is for the header files. For the CPP files, you have to update the
Dev-C++ project itself, so it's better that you decide on the directory
structure before-hand and stick to it.

Hope this helps.

It may not be a match. Try doing such things as casting your
parameters to the ones in StdIcon::Load, e.g.:

Load( (HINSTANCE) x, (int) y); // you probably won't need to cast the int

I've worked through a number of the examples on Reliable Software's
site (<http://www.relisoft.com/win32/>) - that and reinterpret_cast
caused me the most difficulties. For reinterpret_cast, I just replaced
it with a c-style cast (instead of "reinterpret_cast<int> y" I just
did "(int) y").q

By the way, how do you like that book? I really enjoy Bartosz' fine
win32 examples from the link above, esp.the model-view-controller
information.
