any body could tell the correct perameters of logonuser function?
i am having a simple network of two computers and no domain i simple need passworad and user name to enter.
My service is running on one computer where i want to login and i want to login to the system using logonuser api or function but i could not successed yet.
plz tell mee correct parameters of it?
BOOL LogonUser(
LPTSTR lpszUsername,
LPTSTR lpszDomain,
LPTSTR lpszPassword,
DWORD dwLogonType,
DWORD dwLogonProvider,
PHANDLE phToken
);
r00d0034@yahoo.com

Notice this: The LogonUser function attempts to log a user on to the local computer. (LogonUser[^])
If you're trying to do that over the network, it won't work.
You could use OpenSCManager()[^] to open the SCM on the remote machine, then use the other Service Functions[^] to do things with the services on that machine.

Some years ago I made this sample program:
main (int argc, char **argv)<br />
{<br />
BOOL Successful;<br />
HANDLE AccessToken;<br />
DWORD ErrorCode;<br />
char *BufferPtr;<br />
<br />
Successful = LogonUser (argv[1], ".", argv[2], LOGON32_LOGON_NETWORK, LOGON32_PROVIDER_DEFAULT, &AccessToken);<br />
printf ("LogonUser -> %d\n", Successful);<br />
if (!Successful)<br />
{<br />
ErrorCode = GetLastError();<br />
printf ("GetLastError -> %d\n",ErrorCode);<br />
FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM, NULL, ErrorCode,<br />
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR) &BufferPtr, 0, NULL );<br />
printf ("Error String -> %s\n",BufferPtr);<br />
free (BufferPtr);<br />
}<br />
}
However, you should have a certain privilege before you can do this (I can't remember anymore which one it was). Othwerwise you get the following error:
LogonUser -> 0<br />
GetLastError -> 1314<br />
Error String -> A required privilege is not held by the client.
Hope this helps.
Enjoy life, this is not a rehearsal !!!

1) What is the result of GetLastError()?
2) What OS version, SP you are using?
The most common mistake using LogonUser() is that it needs SE_TCB_PRIVILEGE on pre-XP systems. This privilege is (and should be!) granted only to the SYSTEM account, which means that actually only service processes are able to perform a LogonUser()

You learn something every day. I didn't realize that XP removed the SE_TCBNAME privilege requirement from LogonUser.

I have made an application using Dialog Boxes. I want to add a printing feature to print the whole Dialog Box.
Can u help me in this?
help me ,please

Check out WM_PRINT - you can use it to draw onto a printer DC.

But my dialog's items not be drawed in OnPaint().
I use :
dc.BitBlt(0,0,100,100,GetWindowDC(),0,0,SRCCOPY);
it can not work successfully.
dc is the printer's dc here.
can u tell me the code,please!
|
|
|
|

This should work:
RECT rc;
GetWindowRect(&rc);
dc.BitBlt(rc.left,rc.top,rc.right-rc.left,rc.bottom-rc.top,GetDC(NULL),0,0,SRCCOPY);
Of course, it will be the size of a postage stamp until you scale it, unless you have a 72 DPI printer.

thanks.
but it can not work,too.
the printer's document is biger than 160M,and it's turning biger!

Goodness. It's supposed to grab the screen then print only the bits of it that contain the dialog.

It should, if you pass in PRF_NONCLIENT. I've not tried it though...

If you want to draw the entire dialog, I suspect you'll need to capture the screen, then print the part of the resultant bitmap you need. Do you want to print the dialog itself, or only it's contents ? That is, do you want to print the little x to close the window, the frame and the dialog title ?

draw the entire dialog!
i can capture the screen and save in .BMP. but the bit map has no palette. how can i print it!
|

Great - don't save it, just get the co-ordinates of the window and print only that part of it.

thank u.
can u help me check out my code,please?
CDC *pDC=GetWindowDC();
CBitmap bm;CRect rc;GetWindowRect(rc);
int Width=rc.Width();//GetSystemMetrics(SM_CXSCREEN);
int Height=rc.Height();//GetSystemMetrics(SM_CYSCREEN);
bm.CreateCompatibleBitmap(pDC,Width,Height);
CDC tdc;tdc.CreateCompatibleDC(pDC);
CBitmap*pOld=tdc.SelectObject(&bm);
tdc.BitBlt(0,0,Width,Height,pDC,0,0,SRCCOPY);
tdc.SelectObject(pOld);
BITMAP btm;
bm.GetBitmap(&btm);
//
//here. btm can be save as BMP file
dc.StartPage(); // begin new page
Info.m_nCurPage = page;
CDC MemDC;
MemDC.CreateCompatibleDC(&dc);
pOld=MemDC.SelectObject(&bm); ///
dc.BitBlt(rc.left,rc.top,rc.right-rc.left,rc.bottom-rc.top,&MemDC,0,0,SRCCOPY);
///but here .
//not be printed . the printer only print the bits,too.and the size of printer document is big!

This all looks right, I don't get what the problem is. What are the bounds of the bitmap ? Have you tried blting it to the screen ?

yes.
i have tested it.it can be bited to the screen.
my printer is canon lbp_800.
it's my printer's problem?

It's odd, because in theory if you send a 800x600 bitmap to a printer, you should expect to get a very small bitmap, because most printers have at least 600 dots per inch. IF the bitmap is fine, and the printer driver is hanging with a large amount of data passing through, then the problem is most certainly the print code.

then,
how can i do?
save as BMP file,and print it with MS paint?
please

No, that would clearly be a hack. Print some text to your printer, then create a small bitmap programatically and print that. Build your way up until you work out where it is failing, and fix it ( naturally ask questions if you're confused or stuck, and provide whatever info you manage to find on the way ).
