That's the problem, I am using the built in caption of the group box. I'm seeing it display two different ways in two different dialogs.

Hi..
I write a static linked MFC application and i need some advice about reducing the .exe size
I used the compiler optimization option (minimum size) but the release build is still big.

is there any other options?

also is it posible to tell if there are some coding practices to reduce the size ?

can i delete some unnecessary wizard code?

If it's not completely necessary, link in the MFC libraries dynamically. That should reduce your executable size considerably.

The one thing I do to everything I release is add the linker switch /opt:nowin98
That's reduced my binaries by 30K in some cases (which does make a difference for me).

What's that do? It removes any code required for backward 98 compatibility???

RTFM

But seriously - the default behavior of the VC6 linker is to make the PE sections aligned on 4K boundaries, which makes the EXE load faster after being defragged by the Win 98 defragger (which has that gimmick of placing clusters where they'll be read in faster from disk). Adding that switch goes back to the pre-v6 behavior of 512-byte boundaries, which makes for a smaller EXE (less padding within the file to get to 4K boundaries), in exchange for alleged slower loading times which no one will notice with today's hardware.

i wish to know if it is possible to reduce the size if i make my own classes enstead of MFC
for example writing my own CFIle?

Just intercept WM_CLOSE. I think that should work for ALT+F4, close button, close context menu, etc.

Be glad I'm not a user of that program: I'd vote for more torture than the MS Explorer team should have (because they didn't do their stuff conciously malicious that you apparently do).

Now Virus writers are going to force users to write a password to get OUT of their programs?!

Why can't you just SEGV like every nice MS program?!

OK. A serious answer here would then be: replace Explorer.exe with your program. Seriously!

If you _only_ want your program to run on that machine, replace the shell with whatever you like.

But wouldn't that be wasting money for your customers, using full Windows installations as just the back-end for your program?

I have it sorted now, I just trap the WM_CLOSE message, and direct the user to my exit screen, its manly intended to stop the user accidentally closing the program, as they are generally not PC aware, and it would mean a call to the site engineer at 4:00am to go to site to get the system working again because we all know its always the early morning shift (that are bored) that cause these sort of problems and as the system is very expensive 1/4 mill Its a Big Machine the cost of NT4.00 is small, we usually use the policy editor to restrict access.

Thanks for the help

The following code is for get the default printer

<br />
PRINTER_INFO_2 *ppi2 = NULL;<br />
DWORD dwNeeded = 0;<br />
DWORD dwReturned = 0;<br />
<br />
EnumPrinters(PRINTER_ENUM_DEFAULT, NULL, 2, NULL, 0, &dwNeeded, &dwReturned);<br />
    if (dwNeeded == 0) <br />
      return FALSE;<br />
    <br />
    // Allocate enough space for PRINTER_INFO_2...<br />
    ppi2 = (PRINTER_INFO_2 *)GlobalAlloc(GPTR, dwNeeded);<br />
    if (!ppi2)<br />
      return FALSE;<br />
    <br />
    bFlag = EnumPrinters(PRINTER_ENUM_DEFAULT, NULL, 2, (LPBYTE)ppi2, dwNeeded, &dwNeeded, &dwReturned);<br />
    if (!bFlag)<br />
    {<br />
      GlobalFree(ppi2);<br />
      return FALSE;<br />
    }<br />
    <br />
    // If given buffer too small, set required size and fail...<br />
    if ((DWORD)lstrlen(ppi2->pPrinterName) >= *pdwBufferSize)<br />
    {<br />
      *pdwBufferSize = (DWORD)lstrlen(ppi2->pPrinterName) + 1;<br />
      GlobalFree(ppi2);<br />
      return FALSE;<br />
    }<br />
    <br />
    // Copy printer name into passed-in buffer...<br />
    lstrcpy(pPrinterName, ppi2->pPrinterName);<br />

There's a good chance these tips are loaded from resources. In the toolbar's parent window, you can handle TBN_GETINFOTIP to eliminate the default behavior.

29-Apr-02 2:32

hi i have this code that should take the data in "m_copyed" and increment it by the value in "keyvalue".
But i seems to only increment the data by '1' and ignoring the value in "keyvalue"

radio_select=3;
for(int i=m_copyed.GetLength();i--;)m_copyed.SetAt(i,m_copyed[i]+ keyvalue);
SetDlgItemText(IDC_CHANGEDDATA, m_copyed);

i have some extra code in another area of the program shown below code this be the problem>

GetDlgItemText(IDC_EDITDATA, m_typing);
m_copyed=m_typing;

NOTE - i have 2 edit boxs "m_copyed" and "m_typing", i'm taking the text from "m_typing" incrementing it by the value in "keyvalue" and then displaying it in "m_copyed"

any help would be appreciatted
thanks
