Interesting Problem

[William Wheeler]

I am trying to create a base program, or "Hello World" Program if you will, and I created an Icon, made resource.rc, resource.h files, and then went to compile it, and I got the following error Status:

Compiler: Default compiler
Building Makefile: "C:\Documents and Settings\Skipper\My Documents\C++ Files\Test\Makefile.win"

main.cpp:29: error: (Each undeclared identifier is reported only once for each function it appears in.)

make.exe: *** [main.o] Error 1

Execution terminated

The Resource.h file contains the Following Line:

define IDC_MYICON 101

The Resource.rc File contains the Following:

include "resource.h"

IDI_MYICON ICON "raindrop.ico"

And the WinMain:

include <windows.h>

include "resource.h"

/ Declare Windows procedure /
LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);

/ Make the class name into a global variable /
char szClassName[ ] = "WindowsApp";

       );

/* Make the window visible on the screen */
ShowWindow (hwnd, nFunsterStil);

/* Run the message loop. It will run until GetMessage() returns 0 */
while (GetMessage (&messages, NULL, 0, 0))
{
    /* Translate virtual-key messages into character messages */
    TranslateMessage(&messages);
    /* Send message to WindowProcedure */
    DispatchMessage(&messages);
}

/* The program return-value is 0 - The value that PostQuitMessage() gave */
return messages.wParam;

}

/ This function is called by the Windows function DispatchMessage() /

return 0;

}

Any Clues as to what I have done? I only have one thought. Does the .rc file not automagically compile, is there some way that I have to include it other that add to project?

The thread title was a real let down. That was completely uninteresting.

You are however asking for trouble with "C:\Documents and Settings\Skipper\My Documents\C++ Files"!

... actually I mentioned that in the last thread you posted, and you never got back on that, although you obviously got past the problem despite ignoring the advice.

As service to the community, you are asked to provide closure on any threads you start. This one for instance; it might be useful to know what the problem was.

Sorry About the Title.

The Problem was simple, in my Resource.h, I declared IDC_MYICON, and then in WinMain(), I called upon IDI_MYICON.

It was a stupid mistype.

Also Forgot To Mention:

Using DEV C++ Ver. 4.9.9.2

Okay Figured This one Out. Sorry for the stupidity, but Found the problem.
