When I call OpenPrinter, it fails and GetLastError() returns 87 -> ERROR_INVALID_PARAMETER Mad | :mad:

it's the last parameter ! i know this because this is the one i don't know how to init. it's a PRINTER_DEFAULTS struct.

if somebody knows how to init this struct, post me the tips ! Wink | ;)

See you later on the web !

I want to make my program expire after 30 days. What's the best way to implement this? I just need a simple solution, one that will prevent normal users from bypassing the expiration.

Thanks!

1. get the current time
2. read a registry key that your program owns HKCU/Software/MyCompany/Whatever...
3. if that key doesn't exist, create it and write the current time there. this wil happen the first time your app runs.
4. if the key does exists, read the time stamp that was stored there and compare it to the current time.

save lastest date in register or a file, make sure ur user can't find it
avoid to use 'current time', so if user changes time setting, the app still expired

file manager, a open resource for user?

in file manager, we can see many info:
1. disks, folders and files
2. network connections
3. ....

some time i want to access those info directly, but i have no idea.
i.e. 'find file' only can find folder, file and is very slow. if use resource in file manager, it should be faster. and how to get network info?

i guess microsoft keeps it as itsown secret, am i wrong?

GetPrinterDeviceDefaults and NT4

I have a code snippet that just doesn't seem to work on 2 NT4 machines here(Win2K/98 are fine).

Here's the code:

PRINTDLG pdlg;
ZeroMemory(&pdlg, sizeof(PRINTDLG));
pdlg.lStructSize=(DWORD)sizeof(PRINTDLG);
BOOL bVal = AfxGetApp()->GetPrinterDeviceDefaults(&pdlg);

Even though both NT machines have default printers setup, bVal returns FALSE every time.

Any ideas?

ip address, who is god for it?

i connect internet vs telephone line, so i have an ip address (in format of 111.111.111.111). but if i disconnect internet, i have nothing (ipconfig says nothing).

i think the number is related to my internet vender, possible related to my PC (adapter etc) also, maybe more.

i think if i change a vender or change a modem (or PC), the number must be changed.

do you kown story of the number?

thx

if you dial up you will almost certainly get a temporary IP from one of the numbers your ISP has reserved. it isn't related at all to your PC or modem, but it is related to your vendor (ISP).

hmm, I think you need some introduction book to TCP/IP. Maybe "TCP/IP for dummies" will do good to you. At least, I learn a lot from it.

As Chris has said, the IP address is assigned to you by your ISP. usually, your IP is a dynamic one. You don't need to wait for tomorrow, just connect again, and you'll find it's different. Yes, it is different every time. That's how ISP manages the IP address resource.

No worry, just grab a dummy book and get refreshed.

It is. People and companies are assigned blocks of public IP addresses. You can safely use the IPs within your block(s).

includeh10 wrote:

Not really. Your adapter (a.k.a.; NIC) has a MAC (Media Access Control) address, which is supposed to be unique. Your IP address is combined with that to identify you on a network.

Could you rephrase the question?

Cursor with CSplitterWnd, dll, wizard, trick, help ...

includeh101-Aug-02 3:56

1-Aug-02 3:56

i need to update an app with CSplitterWnd in MDI child frame, i meet a very trick thing and can't find solution, please help.

code is very simple:
add a member var in ZMDIChildWnd (sub-class of CMDIChildWnd)
CSplitterWnd m_wndSplitter;

override:
BOOL ZMDIChildWnd::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
return m_wndSplitter.Create( this,2,2,CSize( 10, 10 ),pContext );
}

that is all. code is standard no problem because i got it from visual book.

but problem is about cursor shape:
in dll (use MFC as dll) version, cursor is same as what in visual c++ enviorment (apears when sizing view), but in static library version (use MFC in static lib), the cursor changed to 2 arrays (OCR_SIZENS).

to find problem, i use vc wizard to re-create a blank MDI interface, with choose 'advance button' then select 'use CSplitterWnd'. this time, the cursor is correct in both dll and static version.

because both apps are blank now, i checked every line but can not find any different.

the app to be updated is very large, i don't want to copy all code to a blank one, but i must find solution to use right cursor.

i guess it something wrong in 'setting' ?

thx
