At design time or run time?

A combobox is comprised of two separate controls: an edit control, and a listbox. Which part are you wanting to size?

Sorry for the delay.

At run time, obviously the part of the combo box which contains the edit ctrl.

As was mentioned earlier, use the SetItemHeight(-1, ...) method.

Hi all,
I want to get all printers in my company'LAN,but i just have enumd
printers that is in my computer's workgroup.There are 22 workgroups in my company's Lan.
i have enumed 3 printers by EnumPrinters like this

EnumPrinter(PRINTER_ENUM_REMOTE,NULL,1,pPrinterEnum,dwBytes,&pcbNeeded,&dwReturned);
EnumPrinters
(PRINTER_ENUM_LOCAL|PRINTER_ENUM_CONNECTIONS , NULL, 4, pPrinterEnum, dwBytes,&pcbNeeded,&dwReturned);

so how to get printers in whole LAN?
The same question was when i got computer in LAN,i also have got computer in my workgroup.

my code is here
CString strTemp;
CString strname="";
LPSERVER_INFO_101 pBuf = NULL;
DWORD dwLevel = 101;
DWORD dwPrefMaxLen = MAX_PREFERRED_LENGTH;
DWORD dwEntriesRead = 0;
DWORD dwTotalEntries = 0;
DWORD dwTotalCount = 0;
DWORD dwServerType = SV_TYPE_DOMAIN_ENUM ;
DWORD dwResumeHandle = 0;

NET_API_STATUS nStatus;
unsigned short * pszServerName = NULL;
char szOut[2048];

// Call the NetServerEnum function to retrieve information
// for all servers, specifying information level 101.
nStatus = NetServerEnum(pszServerName,
dwLevel,
(LPBYTE *) &pBuf,
dwPrefMaxLen,
&dwEntriesRead,
&dwTotalEntries,
dwServerType,
NULL,
&dwResumeHandle);

CString strTemp;
CString strname="";
LPSERVER_INFO_101 pBuf = NULL;
DWORD dwLevel = 101;
DWORD dwPrefMaxLen = MAX_PREFERRED_LENGTH;
DWORD dwEntriesRead = 0;
DWORD dwTotalEntries = 0;
DWORD dwTotalCount = 0;
DWORD dwServerType = SV_TYPE_DOMAIN_ENUM ;
DWORD dwResumeHandle = 0;

NET_API_STATUS nStatus;
unsigned short * pszServerName = NULL;
char szOut[2048];

// DWORD i;
// DWORD dwServerType = SV_TYPE_DOMAIN_ENUM; // all servers
// LPSERVER_INFO_101 pTmpBuf;
// Call the NetServerEnum function to retrieve information
// for all servers, specifying information level 101.
nStatus = NetServerEnum(pszServerName,
dwLevel,
(LPBYTE *) &pBuf,
dwPrefMaxLen,
&dwEntriesRead,
&dwTotalEntries,
dwServerType,
NULL,
&dwResumeHandle);

Thanks.
at last .forgive me ,My English is not very good.

If Level is 1, and Flags contains PRINTER_ENUM_REMOTE, and Name is NULL, then the function enumerates the printers in the user's domain/workgroup. Do you (not your computer) belong to the other 21 workgroups? I'm not sure if this is the problem, but it would behoove you to check it out.

Thank you for your reply. I know if Level is 1, and Flags contains PRINTER_ENUM_REMOTE, and Name is NULL, the function enumerates the printers in the user's domain/workgroup.

yes,I belong to the other 21 workgroups .Becausse i can enumerated 22 workgroups name by function NetServerEnum. i also found all of the workgroups in "Microsoft Windows Network".

So,do you have any ways to find all printers /computer ? not just only in my domain. Sniff | :^)

Hello all,
I want to pass class object in my thread.How to do it??
when i m not passing any arguments to my thread then i m calling AfxBeginThread Like this,
pThread = (CMyThread*) AfxBeginThread( RUNTIME_CLASS(CMyThread),
THREAD_PRIORITY_NORMAL,
NULL,
CREATE_SUSPENDED,
NULL);
i have made a class constituting of 2 members CString and int
i want to pass these values in my thread class
i have made a object of this class like this
commo *c;
c = new commo;
then passing its variable values

now i want to pass this object to thread class
when i m passing it to thread class like this
pThread = (CMyThread*) AfxBeginThread( RUNTIME_CLASS(CMyThread),c);
Its giving error
error C2665: 'AfxBeginThread' : none of the 2 overloads can convert parameter 1 from type 'struct CRuntimeClass *'

can anybody help me in this
thanxs in advance

Naveen1-Mar-07 20:20

cast c to LPVOID and then pass

pThread = (CMyThread*) AfxBeginThread( RUNTIME_CLASS(CMyThread),(LPVOID)c);

the commo class is derived from the CWinThread class isnt it?

Put the following macro in the header file inside the public setion of the class

DECLARE_DYNCREATE( commo )

And in the cpp file

IMPLEMENT_DYNCREATE( commo , CWinThread )

sorry sorry my mistake... D'Oh! | :doh:

actually CMyThread need to be derived from CWinThread and those macros need to be put in that class.

neha.agarwal271-Mar-07 21:08

CMyThread Class is derived from another class WinTimerthread and this class is derived from CWinThreadClass
Now what i have done is i have declared both variable in WinTimerThread Class instead of commo class
and in my main class passed values it those two variables of WinTimerThread class
but againits giving same error Cry | :((
