Yes, absolutely.
In debug mode it compiled and run (!) OK.
I switched on release mode and all these calls

HtmlHelp(m_hWnd, "c:\\x\\uploads\\help\\eehelp.chm::/main.htm",HH_DISPLAY_TOPIC, NULL );

were not compiled:

C:\x\Source...cpp(334) : error C2065: 'HtmlHelp' : undeclared identifier
C:\x\Source...cpp(334) : error C2065: 'HH_DISPLAY_TOPIC' : undeclared identifier

again: in Debug mode it not only compiles it even runs well...

Looks like you may have added the the HtmlHelp include and library paths for the "Debug" configuration only.

More Registry questions

Hi,

I've noticed a lot of questions dealing with the registry. However, none of them seem to relate to my particular problem.

I need to specify exactly where my program's data goes. My problem is that when you call SetRegKey(), it automatically makes a folder for your program within the folder that you specified using SetRegKey() and I don't want that. I wish to put my data in another program's folder.

Thanks in advance,

Use the Registry API functions.

I hate to be slow, but could you give an example of the RegCreateKeyEx (I've not looked at the others). One of the "out" parameters confuses me.

Thanks,

Never use KEY_ALL_ACCESS! If you do, the call will fail on NT if the user is not admin. If you need full read/write privs, use KEY_READ|KEY_WRITE instead.

Happy b'day BTW Wink | ;)

CDialog & Multithreading :: MFC

Ok, it's all looking good and better. I used Michel Dunn's idea. So this is my code:

        HKEY hKey;   
	DWORD dwDisposition;   
	RegCreateKeyEx(HKEY_CURRENT_USER,"Software",0,"",REG_OPTION_NON_VOLATILE,KEY_READ|KEY_WRITE , NULL,&hKey,&dwDisposition);
	AfxGetApp()->WriteProfileString("Cloaked Chat", "Test", "Test");
	RegCloseKey(hKey);
</code>

It all compiles error free, but do I need to set some values for the "hKey" and "dwDispostion"? When I ran the above code, nothing happened. Shouldn't it have made a folder called test with the string "test" inside the folder "Cloaked Chat" of the software folder?

Thanks,

Hi.

I have a class derived from CDialog for a dialog box. I implement a worker thread. I would like to post and/or send messaged directly to the dialog box class instead of going to main frame first. Is that possible?

Thanks,
Kuphryn

Yes. CDialog is derived from CWnd. Thus you can use CWnd::PostMessage

Okay.

I called PostMessage() with m_hWnd. However, the compile responded with an error that m_hWnd is unknown. What do I pass to PostMessage() such that the dialog class will handle the message?

Nish Nishant19-Jun-02 13:55

You don't need to pass an HWND if you are using CWnd::PostMessage.

You need a pointer to your CDialog derived class, say m_pDlg.

Now simply do this :-

m_pDlg->PostMessage(message,wparam,lparam);

ATL Server

Thanks in advance for any help. I am trying to create an ATL server using the example "Building an Office2K COM addin with VC++/ATL". I am having a problem with the imports. Here is my stdafx.h:
// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently,
// but are changed infrequently

#if !defined(AFX_STDAFX_H__613C434D_55D9_45D2_937E_C26FA13D3F22__INCLUDED_)
#define AFX_STDAFX_H__613C434D_55D9_45D2_937E_C26FA13D3F22__INCLUDED_

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

#define STRICT
#ifndef _WIN32_WINNT
#define _WIN32_WINNT 0x0400
#endif
#define _ATL_APARTMENT_THREADED

#include <atlbase.h>
//You may derive a class from CComModule and use it if you want to override
//something, but do not change the name of _Module
extern CComModule _Module;
#include <atlcom.h>

//{{AFX_INSERT_LOCATION}}
#import "C:\Program Files\Common Files\Microsoft Shared\Office10\mso.dll" rename_namespace("Office") named_guids
using namespace Office;

#import "C:\Program Files\Microsoft Office\Office10\MSWORD.olb" rename("ExitWindows", "WordExitWindows"), named_guids, raw_interfaces_only
using namespace Word;

// Microsoft Visual C++ will insert additional declarations immediately before the previous line.

#endif // !defined(AFX_STDAFX_H__613C434D_55D9_45D2_937E_C26FA13D3F22__INCLUDED)

Unfortunately, I keep getting the error message:

StdAfx.obj : fatal error LNK1179: invalid or corrupt file: duplicate comdat "_IID_CanvasShapes"

Any ideas what I need to do to fix this problem? I am new to ATL but I was thinking the "using namespace Word" should have taken care of any duplicates. I used the article as an example because I am not using Outlook, instead I am using MS Word. Any thoughts?

Registry Theory Question

Hi,

I have recently been working on my first big C++ application, and it has quite a lot of persistent Registry entries.

Anyway, when I want to know an app setting, I am doing AfxGetApp()->GetProfileXXX... to get the setting.

My question is this: is it slower to keep calling that function or to hive off the settings and keep updating that hive if the settings are changed?

Example #1:

A loop 10,000 times with a Registry call each loop is probably slower than reading the value out and then looping 10,000 times.

Example #2:

An event fires (such as WM_CHAR) that reads a setting and uses it once before the end of the handler. Is this slower than having the external hive?

Input, ideas and peep's programming practices in this field greatly appreciated.

Thanks in advance,

Si
