Here's an example that makes the font bold. This is untested, and it's 3:25 AM, so please test before checking the code in. Wink | ;)

HFONT hCurrFont, hNewFont;
LOGFONT lf;

// 1. Get the button's current font.
hCurrFont = (HFONT) SendDlgItemMessage ( hMyDlg, IDC_MY_BUTTON, WM_GETFONT, 0, 0 );
GetObject ( hCurrFont, sizeof(LOGFONT), &lf );

// 2. Change the font however you want by tweaking the LOGFONT members.
lf.lfWeight = FW_BOLD;

// 3. Create a new font.  Note that in "real" code, you should save this HFONT somewhere and delete the font when the dialog closes.
hNewFont = CreateFontIndirect ( &lf );

// 4. Make the button use this new font.
SendDlgItemMessage ( hMyDlg, IDC_MY_BUTTON, WM_SETFONT, (WPARAM) hNewFont, TRUE );

I've noticed the question asked around a lot
but no one seems to answer it, but I'll ask here

There are many packet sniffer and Firewalls for windows, but no free source ones to look at to see how it works
Does anyone have any idea, or tips they would like to share on how one would go by developing one

Thanks for any replies

When a DLL unload from physical memory??

HI,

I wonder when a DLL unloads from PHYSICAL memory...

I found that each process which attach a DLL has a

referrence count for use of it..

And when the count becomes zero it is detached from

process and removed from process's VIRTUAL memory

address..

THEN,.....When exactly a loaded DLL unloads?

(I mean when = which state that satisfies its

unloading condition)

Does it unload itself?
OR
Windows OS unloads it?

Thanks in advance..

I think a DLL unloads from physical memory when this memory it's needed. As when Windows loads a DLL, it only reserves the virtual memory and maps it to the DLL. If the DLL was not loaded, when the process access it, it causes a page fault, and automatically Windows loads it into physical memory. I suppose the it's the same process when unloading: removing the DLL from memory if RAM it's not needed is a silly task, as maybe Windows must reload the DLL after removing it. I suppose the RAM pages containing the DLL will be marked as they can be used, but if anybody uses this pages, 'reloading' the DLL into physical memory will be a little effort. If I find more information I'll post another message, or if anybody can assure this or correct me, will be pleased!!! Smile | :)

_AfxGetComCtlVersion

28-Jun-00 9:19

Hi all,

I found following snippet in \vc98\mfc\src\afximpl.h, which looks very interesting:

// for determining version of COMCTL32.DLL
#define VERSION_WIN4    MAKELONG(0, 4)
#define VERSION_IE3     MAKELONG(70, 4)
#define VERSION_IE4     MAKELONG(71, 4)
#define VERSION_IE401   MAKELONG(72, 4)
extern int _afxComCtlVersion;
DWORD AFXAPI _AfxGetComCtlVersion();

No more determing COMCTL's file version? Instead simply call:

if (_AfxGetComCtlVersion() >= VERSION_IE3)
{
    //...
}

Or do I misaccept something? Can anybody comment on this?

Thanks in advance,
Thömmi

I am making a small application that has an system tray icon. I have created two menu one dynamically and another from resource. But I can't connect the two menu's to the tray icon. The problem is when I move the mouse over the icon without even clicking the menu from resource is popping up. I am using TrackPopupMenu(). Can you help

Re: Interface

You're not checking the event that happened over your tray icon. You should display your menu only if the mouse event was WM_RBUTTONUP, ie:

// in main message-handling switch
  case WM_TRAYICONCALLBACK:  // or whatever you call your callback message
    {
    if ( MY_TRAY_ICON_ID == wParam &&
         <font color=red>WM_RBUTTONUP == lParam</font> )
      {
      // Now call TrackPopupMenu()
      }
    }
  break;

How to view the files from a zip files

Hello,

I am using InfoZip library to one of my application(zipdll.dll and unzdll.dll). I want to list out all the files in a zipped file without unzipping. Please let me know how to get this.

Thanks in advance.

Focus on reading the file headers from the ZIP file.
They contain the information you would want to know about the files and folders without unzipping.
There should be a function to read or enumerate through the headers.

LNK2001 in MFC Extension DLL's

Hello!

I got a strange linker error
(EFDBListCtrl.obj : error LNK2001: Unresolved external Symbol "public: static struct CRuntimeClass const CEFListCtrl::classCEFListCtrl" (?classCEFListCtrl@CEFListCtrl@@2UCRuntimeClass@@B)
and
EFDBListCtrl.obj : error LNK2001: Unresolved external Symbol "protected: static struct AFX_MSGMAP const CEFListCtrl::messageMap" (?messageMap@CEFListCtrl@@1UAFX_MSGMAP@@B))

The error only occur on following circumstances:
CEFListCtrl exists in MFC_Extension-DLL_A
CEFDBListCtrl exists in MFC_Extension-DLL_B
(CEFDBListCtrl inherits from CEFListCtrl)

When putting CEFDBListCtrl out from DDL_B into the EXE-Module everthing works fine.
I think the project settings are OK (linking with lib's..)
there are no unresolved externals for other functions of
CEFListCtrl.

Well, First check if you are exporting and importing OK.

CWnd and scrolling...

Member 91827-Jun-00 15:49

Hello, I'm trying to create a control that's derived from CWnd, has a scroll bar, and dynamically adds several CStatic's that are displayed in the initial view and when the user scrolls downward (this is also in a dialog). My problem is that when I create a control and set its' position so that it can't be seen until you scroll down, it never appears. Only the CStatic's I create that are within the initial view ever appear.

what is the bellow macro mean? (in icrsint.h)

"#define classoffset(base, derived) ((DWORD)(static_cast<base*>((derived*)8))-8)
"

I think it offset to the vtable of the base class. is it right?

SetCommBreak

Barry Zhao27-Jun-00 10:47

Hi,

I have some codes developed using VC++6.0 on Windows 2000 Professional RC3:

...
SetCommBreak(commPort);//comPort is a handle to com1
sleep(certain_value);//
ClearCommBreak(commPort);
...

I have a sniffer program running on another pc B which has special cables connected to the pc A running above program, and A is connected to pc C.

B detects one and only one byte which is 0x00 when above codes are executed when certain_value is larger than 10, and sometimes none or 0xff when certain_value is less than 3. I am pretty confident the sniffer program is OK.

My question is: is data 0x00 supposed to appear on the line?
What I want is to send a break signal from A to C AND C won't think A sends some thing before the break signal.

By the way, I have tried PurgeComm(..) before setcommbreak, it doesn't work.

Is it a W2K thing or this is the way it works?

Thanks a lot

Barry

Hi,

I had the same situation a LONG time ago... When I was setting\clearing the break signal one character (0xFF) was transmitted. In my case it was not a problem, because as soon as I detect a Break signal I clear all my buffers. Probably you should change the way you exchange the data, so that an extra character will not destroy the information. Think about something old and simple as Kermit/XModem/YModem protocols.

I need to save a key and all it's subkeys.
The key is: HKEY_CURRENT_USER/Software/{company name}/{app name}

I then need to restore all those keys to a new {app name}

How do I do that ?

I know the functions: RegSaveKey and RegRestoreKey, but I need to do that under win95/98 also and RegRestoreKey is not available under these OS.

thanks,
Louis.
