HI.
I´m developing a database application using ADO and, although it´s a large program i don´t want to use more than 2 or 3 open connections.
The problem is that i can´t define a global connection pointer, right now, i can only make it work creating a new con in every cpp file.
I´ve tryed defining a global pointer in every way i know but I´m allways getting memory or even weirder errors.
Can anyone help me out?

Global variables are the work of the devil, but if you must, the best way is to make it extern in stdafx.h, and declare it in stdafx.cpp. Assuming you're using MFC, I'd put it in CMainFrame, because a pointer to that class is so easy to get ahold of from anywhere in your application - CMainframe * pMain = dynamic_cast<CMainFrame*>(AfxGetMainWnd());

I want to lock Internet Temporary folder. Don't permiss IE save any file to this folder!
If you have any infor please show it for me!

I have not tried this out. But you could rename it temporarily and then rename it back. Poor IE wont be able to write into it, because it won't exist. But you never know, perhaps it will create it again.

If you're using NT, you should use NTFS. If you are using NT and NTFS it's obvious: Don't give anyone but "System" any access whatsoever to the temp folder.
Please report how hard MSIE crashed.

- How to modify the color of the caption of a button(not including the background of the button)?
- Regards,

Two ideas:
- handle WM_CTLCOLORBTN (MSDN: "By responding to this message, the parent window can set a button's text and background colors")
- use ownerdraw buttons (see BS_OWNERDRAW)

- Thanks, Paolo pal!
- I have never used "WM_CTLCOLORBTN" before (even not heard it). Since I am a newbie, can you show me an example?

- Sorry for interrupting again, Nish pal!
- I still have a question. After reading the article you introduced to me, it seems that we can not use these messages now. Are there any other methods to change the color of the caption of the button?

Is it possible to create a window that will render HTML, something like internet explorer. As our product is dependant on the version of the common controls dll that comes with IE5 I know IE5 will be installed so can I actually use the 'Internet Explorer_Server' window class. I am restricted to the Win32 API so the MFC solutions such as CHTMLView are not available to me. Any information you can provide would be greatly appreciated.
Steve.

A small update...
Something like:
schService = CreateService(
schSCManager,
TEXT(SZSERVICENAME),
TEXT(SZSERVICEDISPLAYNAME),
SERVICE_ALL_ACCESS,
SERVICE_WIN32_OWN_PROCESS,
SERVICE_DEMAND_START,
SERVICE_ERROR_NORMAL,
szPath,
NULL,
NULL,
TEXT(SZDEPENDENCIES),
NULL,
NULL);

Under VC++, I made a DLL as -Win32 Dinamic Link-. It has only one ".C" file containing the DLLMain two Function and the callback function. The first function loads the callback function and the second function unloads the callback function. Here is how the callback is loaded:
HHOOK hhGetMsg;
HINSTANCE hInstance;
LRESULT CALLBACK GetMsg (int iCode, WPARAM wParam, LPARAM lParam);
{
hhGetMsg = SetWindowsHookEx (WH_GETMESSAGE, (HHOKPROC) GetMsg, hInstance, 0);
}
with the GetMsg sending messages to a window everytime a message pops-up. There are no filters so all messages are SUPPOSEDLY "trapped". I used SendMessage to avoid a mess. Also calls CallNextHookEx.
I have looked at other codes that SUCCESSFULLY loaded a system-wide hook and My code are basically Identical. But my hook only monitors the APP/.EXE that loads it! I don't get it! The DLL and its functions are loaded from the APP/.EXE using LoadLibrary and GetProcAddress.
Need help! Thanks in advance.

I guess your problem is don't put any global data in a shared section, all data you use in your hook function must be placed in a shared section so it is same as multiple DLL instances.
here is a my snippet of code...
#pragma data_seg(".shared")
HHOOK g_hMouseHook = NULL;
HINSTANCE g_hInstance = NULL;
MOUSEHOOKSTRUCT* g_pMHS = NULL;
HWND g_hLastWnd = NULL;
UINT g_nLastMessage = 0;
UINT g_nLastHitTestCode = 0;
#pragma data_seg()
#pragma comment(linker, "/section:.shared,rws")
look at MSDN for more about shared section.

I actually just created a system-wide keyboard hook. It was my very first time, and I managed to do it without any knowlegde of what you're talking about. I don't even understand what it means Anyway, I didn't use any #pragma preprocessor commands or anything special. If you want to check out my source, just tell me...

I need to do something when a file is opened using the menu of a SDI application.
I tried handling the ID_FILE_OPEN message, but that removes the open dialog. I still want it to happen, but I need to do other things.
Where do I do this?
Thank You

The document recieves a OnFileOpen message, you can do it there.
