What about just using an accelerator?

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?!

It's not me just my customer that request this function, the end software is used for process control, and they do not want the employee quitting the program to play card game ect.......

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?

Thanks, am looking into the references

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

Anyone here used the enumPrinters API? Got some code or know where I can find some?

Any and all reference welcome.

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.

help needed

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

You've forgotten the most important thing: where is keyvalue set, and what to ?

ive just declared it as an 'int'
and set the edit text to m_key="ENTER KEY";

not sure where else i should set the value

thanks for the help

29-Apr-02 2:51

But to what value and where ? What are you trying to achieve ?

29-Apr-02 3:05

i havent set it at any value.

when the program is ran, the user enters a value which is stored as "keyvalue".
This value say '2' is used to move the text in "m_typed" by 2 positions. So if the word was 'SUMMER' it would become 'UWOOGT'
