Did you include the following header file
#include <math.h>

I understand that all *.cpp files in Visual C++ must
start with ...
<br />
#include "stdafx.h"<br />
... how can I make my C++ code portable with such
a restriction?
I tried this ...
<br />
#ifndef GNU<br />
#include "stdafx.h"<br />
#endif<br />
... but that doesn't seem to work.
What should I do if I want my code to compile under
more than ONE compiler?

For portable files you probably don'twant to use stdafx.h, which means no precompiled headers. Just set the Precompiled Headers switch for such files to "Not using precompiled headers".

thanks!
okay how do I do that?

I fell so dumb and inadequate today ... yesterday was such a good day!
I have a CButton derived button in a dialog ( a dialog app ) :
#include "MyButton.h"
CMyButton m_HelpButton;
and
...
void CTestColorControlDlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_HELP_BUTTON, m_HelpButton);
}
...
My button is working nicelly, but I don't receive and message for WM_CREATE, or even the OnCreate virtual is not called.
I need to change the button size, from inside the class, at creation time; I don't want to have to manually create the button in the dialog's OnInitDialog just to do it.
Thank yo for helping a programmer in need!

You don't get the WM_CREATE message because windows creates a normal button first, and then subclasses it in the first call to the DoDataExchange method. When your class is attached to the button, the button has already been created.
You may be able to do want you want in the PreSubclassWindow() virtual method - this is called after the HWND is attached to your button, but before the window procedure has been replaced.

Controls created via a dialog template do not recieve the WM_CREATE message. Handle all control initialization in PreSubclassWindow() instead.

Hello,
I am trying to use SHGetFolderPath in MFC app, however, I get error C2065: 'SHGetFolderPath' : undeclared identifier.
I have latest SDK, WinXP, and included the required header file shlobj.h.
if(SUCCEEDED(SHGetFolderPath(NULL, CSIDL_HISTORY, NULL, 0, lpPath)))<br />
{<br />
::SetCurrentDirectory(lpPath);
}
Why can't the linker find this shell function?

This is strange. According to my version of MSDN (October 2000), ShGetFolderPath is included in shfolder.h/shfolder.lib. However, my version of VC6 does not come with a shfolder.h. I also did a search for the function in any of the header files, and nothing.
Regards,
Alvaro

don't know what version of MSDN you have but mine shows
Windows NT/2000: Requires Windows NT 4.0 or later.
Windows 95/98/Me: Requires Windows 95 or later.
Header: Declared in shlobj.h.
Import Library: shell32.lib.

I did a search for *.h file containing 'SHGetFolderPath' and I got it in ShlObj.h and ShFolder.h in Feb 2001 PSDK (last one I got for VC6) and also the same two files in the PSDK that came with VS.NET.

SHFOLDERAPI SHGetFolderPathA(HWND hwnd, int csidl, HANDLE hToken, DWORD dwFlags, LPSTR pszPath);<br />
SHFOLDERAPI SHGetFolderPathW(HWND hwnd, int csidl, HANDLE hToken, DWORD dwFlags, LPWSTR pszPath);<br />
#ifdef UNICODE<br />
#define SHGetFolderPath SHGetFolderPathW<br />
#else<br />
#define SHGetFolderPath SHGetFolderPathA<br />
#endif // !UNICODE
Sanity check:
I included the shlobj.h file, also, that file is in the SDK, and the SDK source files are in my included paths to search for while linking code.
it still doesn't work, am I missing something obvious?

The lines you quoted above are enclosed within:
#if (_WIN32_IE >= 0x500)
...
#endif // _WIN32_IE >= 0x500 Ensure you have _WIN32_IE properly defined.

If you are getting error C2065, that is a compiler error, not a linker error. You need to make sure the SDK include directories are listed first (Tools menu, Options, ...). You also probably need to define the WINVER variable in stdafx.h to be 0x500 or greater.

I was wondering if one can still use direct video memory access in text mode to write characters to certain screen (screen now-a-days would just be a console window) positions.
In visual C++ 6, is there anything special you have to do to be able to use address 0xB8000000 in this way? I was thinking that the address should still be used for the console windows to maintain backwards compatibility with the old DOS applications, but maybe the console windows used by win32 console applications are quite different from the command line windows?
Thanks

The console windows are different in that they get the protection of the HAL, so direct video memory access is forbiden. Otherwise, you could access any hardware directly just by running through a console window and that would be a serious breach.
|
|
|
|
|
So is there a way to compile the program in visual C++ to be run within a true command window? I guess I'd need to be able to turn off the whole win32 as the target platform thing... I am not sure that is possible.
