#including resource file causing window procedure to be undeclared???

ubergeek · #1 06-Feb-2005, 14:16

ok, this is getting really annoying. i have this program that, so far, just displays a window with an edit control in the middle and exits when you press escape. it doesn't even have a menu. however, i am trying to add a menu now, and therein lies my frustrating problem. when i add the include line at the top of my program after the inclusion of my header file and windows.h but before my function declarations, like this:

CPP / C++ / C Code:

#include <windows.h> //for all winapi calls
#include "geekedit.h" //id definitions
#include "geekedit.rc" //menu -- why is it causing MainWndProc to be undeclared???

LRESULT CALLBACK MainWndProc(HWND, UINT, WPARAM, LPARAM); //window procedure
bool MainWndCtrlProc(HWND, WORD, WORD, HWND); //processes WM_COMMAND messages from main window
LONG FAR PASCAL MainWndEditCtrlSubProc(HWND, UINT, WPARAM, LONG); //subclassing process for main window edit control
WNDPROC OldEditCtrlWndProc; //original main window edit control window procedure
void createEditControl(HWND); //make the main window's edit control, set its font, and subclass it
void checkSave(HWND); //called on program quit -- if the file has been modified since the last save, prompts for saving
void saveOptions(HWND); //saves options to .ini file when preferences window is closed

and then try to compile, i get these errors:

This seems to be saying that something in the resource file is making my window procedure, MainWndProc, fail to be declared (even though it is declared in plain sight on the line below the include statement).

can anyone help? the attachment mechanism is not working for me right now, so my complete source files are posted here:
http://www.geocities.com/zapguyd/dow...ekedit.cpp.txt
http://www.geocities.com/zapguyd/dow...geekedit.h.txt
http://www.geocities.com/zapguyd/dow...eekedit.rc.txt

things of note:
1. if i comment out #include "geekedit.rc" then there are no errors.
2. this program is a work in progress, so there may be things in the code that are not commented out--these are things that are buggy right now, or that i have replaced with something else and have not gotten around to deleting yet. right now i am just trying to figure out this one problem; everything worked before i tried to include the resource file.
3. the compiler errors seem to indicate that there is also something wrong with the

CPP / C++ / C Code:

ID_MAINWNDMNU MENU

line in my resource file. i suspect that this may be the root of the problem. does anyone know the correct syntax that i should be using here? (i did try adding DISCARDABLE to the end of that line, but it didn't change anything)
4. i realize that the line that will actually add the menu to my window class is commented out. again, i am just trying to fix this problem, then i will move on.

You don't include resource files, use pragma, like so:

CPP / C++ / C Code:

#pragma resource "resource.res"

Or link it to your object file(s) when compiling.

but my resource file is not geekedit.res, it is geekedit.rc
i replaced #include "geekedit.rc" with #pragma resource "geekedit.rc" and i get these errors:

apparently i do not have the correct format for a menu in a resource file

i would be greatly obliged if someone could help with this latest quagmire ;-)

nevermind

apparently i don't even have to use the #pragma, just adding the resource file to the dev-c++ project does it

also, i didn't have the values for the menu items #defined....doh!

anyway, it works, thanks dr. evil
