I'm working on a project which involves printing invoices. Those invoices have predefined layouts (more than one) which may contain tables(of purchased products), images and so on. What should i use for displaying/printing them?. I've used an activex ie control and XML/XSL generated pages for this kind of work in the past but now i need pagination and some other features that html cannot provide. Generating pdf files is also an option but i don't know which api to use

   Straight ASCII and Form Feed characters! :P

   Seriously, I would think that something like PDF would work well here, as would something like a reporting package (like Crystal Reports).

   There are APIs that allow you to programmatically create a PDF document, but I do not know of any free ones.

   Peace!

Disable selection highlighting in a CTreeCtrl

Hi,

Please help me find a way to disable or change the color of the selection highlighting in a CTreeCtrl. It is the same selection highlighting that is expanded by enabling the "FullRowSelect" option of a CTreeCtrl.

Thanks.

Hi,
I try to translate text to text in True DBGrid control, but it seems not work in VC++, my code list below:
....
CValueItems oValueItems;
oValueItems = m_CtrlTDBG.GetColumns().GetItem(&index).GetValueItems();
CValueItemDisp* pValueItemDisp = new CValueItemDisp();
pValueItemDisp->SetValue(old_value);
pValueItemDisp->SetDisplayValue(new_value);
oValueItems.Add((LPDISPATCH)pValueItemDisp);
oValueItems.SetTranslate(TRUE);
....
I don't know how to use the function CValueItems.Add(LPDISPATCH vItem), someone can give me any suggestion? Thanks!

Hello !

I want to find out whether the current logged in user is Domain user or a Local system user. What I mean Is whether user is logged to Domain or a local system.

Is there any API I can use to determine this???

Thanks.

Possibly. Check out NetUserGetInfo() and NetWkstaUserGetInfo().

Hi !
Thanks for the reply..

I am using NetUserGetInfo() to get the user information and SID.
I used LookupAccountSid() to get the domain name.

Now if user is Local user, domain name will be local machine name and if he is a domain user then domain name will be set accordingly.

But how to determine this as domain-name and machine name can be same..

Thank u.

What do USER_INFO_2.usri2_logon_server and WKSTA_USER_INFO_1.wkui1_logon_server indicate in that situation?

I believe that you can use ::GetUserNameEx(...) with a name format parameter of NameSamCompatible. That format will reutrn the username in DOMAIN\USERNAME format, and I believe that if you are logged in locally, the DOMAIN portion will be the Computer Name (See ::GetComputerName(...)/::GetComputerNameEx(...) for the computer name).

Peace!

Property Sheets and OnInitialize()

Hi, I'm displaying a Property Sheet (3 tabs) and whenever I select the tab I need the first time, my sheet displays correctly. However, subsequent selections do not display properly. Is there a way to force a OnInitialize() operation on the form again? Maybe something like an invalidate - though, I am programming in MFC.

What version of VC++ are you using? With v6, property pages use OnSetActive() when the page becomes active.

You can't use LPCSTR here because of the constantness. But how about this:

LPTSTR result[150];<br />
_tcsncpy(result, str.GetString(), 150);<br />

The person that replied to you made a typo, the code should be:

TCHAR result[150];
_tcsncpy(result, str.GetString(), 150);

If you are using a CString, you there is a built in operator that will return an LPCTSTR, so you do not have to use GetBuffer(...) or anything like that to get a const pointer.

Peace!

When using a method that is specific to a particular VC++ version, it helps to state such.

From MSDN

// example for CString::GetBuffer
CString s( "abcd" );
#ifdef _DEBUG
afxDump << "CString s " << s << "\n";
#endif
LPTSTR p = s.GetBuffer( 10 );
strcpy( p, "Hello" ); // directly access CString buffer
s.ReleaseBuffer( );
#ifdef _DEBUG
afxDump << "CString s " << s << "\n";
#endif

There you will find many other conversions as well.

why don't you just do :

CString str = "hello world";
 
(LPCSTR)str;    // used as you like
                // either used with strcpy to be copied, or passed as a function parameter

Don't know where to start ?
