Does anyone know how to change paper size while printing under MFC?
The idea is that page sizes are supposed ti differ from page to page (custom sizes)
|

Had slight computer problems.

Do you want to change the paper size during a print job or do you want to have different paper sizes for each print job?
If you want to set the paper size for a print job you have to get the printer DC and then you can change the dmPaperSize member of the DEVMODE structure.
But I think you should give some more information what you exactly want to do.

Different paper sizes in one print job, every page different, not standard but custom (arbitrary) paper sizes.

You'll need probably different print DC to each page.
CPrintDialog dlg;
HGLOBAL hDevMode = dlg.m_pd.m_hDevMode;
DEVMODE* dm;
CDC dc;
::GlobalAlloc(hDevMode, sizeof(DEVMODE));
for (i = 1; i <= nNumOfPages; i++)
{
if (dm = (DEVMODE*)::GlobalLock(hDevMode))
{
dm->dmPaperLength = 123;
dm->dmPaperHeight = 456;
::GlobalUnlock(hDevMode);
}
dc.Attach(dlg.GetPrinterDC());
dc.DeleteDC();
}

Doesn't work on all printers, on many it sets the paper size to deafult. I also need to get the orginal paper sizes from devmode, but it doesnt always report them correctly (sometimes both are 0).

Hi i am adding to the ms -access database through the MFC code
CRecordset. Prior to adding the record last designID was 74
<br />
CRSDesign dRS(pdb);<br />
<br />
if(!dRS.Open ())<br />
return FALSE;<br />
if (!dRS.CanAppend ())<br />
return FALSE;<br />
<br />
dRS.AddNew();<br />
dRS.m_DesignName = DesignName;<br />
dRS.m_DesignType = DesignType;<br />
dRS.m_Remarks = Comments;<br />
dRS.m_D_Designer = Designer;<br />
dRS.Update();<br />
<br />
dRS.Requery ();<br />
dRS.MoveLast ();<br />
long DesignID = dRS.m_DesignID ;<br />
AfxMessageBox(_ltoa(DesignID,cc,10)); ---> 74<br />
Message box also gives design id as 74. How to overcome this.?
Well
Select @@IDENTITY as num FROM B_DESIGN
query with MS- Access Database does returns just
0
0
0
0
0 For the number of record i am having in my table
Main Problem
DesignID is autonumber field in my data base and is primary key
It is having following values:
12
15
23
70
71
73
74
112
Now when i am running following query into data base (MS-Access query)
SELECT Last(DesignID) FROM B_Design
it returns 74
Even i put a loop after requery and getting designID in message box it starts from 112,5,12,15 .......
When i move recordset to MoveFirst() it will give designID - 112
and when MoveLast() then it will give 74
Have any body idea about this?
How to resolve this problem?
If any more clarification is required please ask for that?
|
|
|
|
|
How about using
SELECT Max(DesignID) FROM B_Design
instead?

Hi,
For memory stats we have overloaded the operator new in such a way that it allows us to allocate memory and store information about which module is doing it. This is all great.
However, now that we have moved to a multi-threaded environment, do we need to protect the call _malloc_dbg(...) (in a debug build) and the ::operator new(...) (in non-debug) with a critical section?

in dos one could access hardware directly because dos's singe-threaded. multi-threaded oses like windows have to take care themselves that hardware pieces are accessed by just one program at a time.
this means for you that not you're allocating memory, but the os's doing it for you; you don't need any multithreading resource-locking techniques at all.

Multithreaded operating systems do not protect your from accessing hardware at the same time. Two threads can access the same page of memory and cause all sorts of mess if locking isn't used to manage the data in the page.

I'm going to patent thought. I have yet to see any prior art.

When you build with the MT (multithreaded) CRTL (c run time library), you will be getting the multithreaded version of new and delete which have built in locking support. You don't have to worry about it.

Hello Friends ,
We are very glad to invite to join our C/C++ Community.
Q : Who We are ?
Ans : we are community of 700 C/C++ programmar.
Q : What we do ?
Ans : We dicuss all about C/C++ ( but strictly
only about C/C++ ).We answer each others
query.We do Projects also on this group by
forming small team among our self.We discuss
about almost all the compilers.
(gcc,turbo,borland ,visual,quick ...)
Q : What do we want ?
Ans : We want to bring all Indian C/C++ programmers
together at one place, PROGRAMMERS TOWN
if you know/love C/C++ programming
you should join us.
IF YOU DON'T KNOW C/C++. DO NOT HAVE ANY
RELATION WITH C/C++. YOU CAN HELP US BY
FORWARDING THIS INVITATION TO EVERY
PROGRAMMER YOU KNOW,
ALL YOUR FREINDS, ALL YOUR COLLEAGUES,
ALL JUNIOS,CLASSMATES, SENIORS .TELL THEM
TO FORWARD IT TO THEIR FREINDS AND LET THIS
TRADITION GO ON. AFTER SOME TIME THIS CHAIN
WILL SURELY REACH TO A C/C++ PROGRAMMER,
THAT IS WHAT WE WANT.
Q : How it is useful for me ?
Ans : you can ask your doubts , you can asnwer

and click on join button .
Suggestion :
as we are around 700 members in this group,
its very high traffic every day 8-10 mails.
so its better if u subscribe using daily
digest option u ll get only one mail per day,
which will contain all the mails of the day
(size won't be much its text only, no attachment).
How to use dialy Digest Option that you will come
To know after joining this group.

hello everybody,
i like to develop a parser which should parse the user given inputs..
exampl,
----------------------------
# code
ln 123,232,23,223;
mycircle 233,343,12;
Textout "text",23,23,"2";
# end
when i run the program, the user pinputted codes should be mapped with the vc+++ Line,Circle,Textout routines with app.parameters provided by the user.
suggest me an idea to solve this..
with regards,
Mahes

Hello everyone,
I've got quite some problems with programming a Context Menu Handler in
Visual C++ (6.0, SP5) under Windows 2000.
I am German and an apprentice, which means I am spending half the time in school and half the time in the company that hired me as an apprentice.
I am studying to become an application developer.
Until now, I only wrote basic C and some more advanced Java Code. A few
days ago, I received a new project:
I should create a context menu entry (submenu with 2 or more menu items). Selecting one of these entries should start the corresponding application.
I read several "Context Menu"-Pages until I found out that, in order to have a sub-menu, I would have to write a COM-DLL, a "context menu handler".
Reading on that topic in the MSDN did not help me much, as I have not programmed (in the?!) COM yet.
I then stumbled upon Michael Dunns "The Complete Idiot's Guide To Writing Shell Extensions" and downloaded his example projects.
Well, it did not work. The example projects were compiled (0 errors, 0 warnings), registered (regsvr32 dllname -> Registration Successful) and written into the registry (shellex->ContextMenuHandlers), mostly as scripted in the RGS-File of the project.
I tried several of the example projects, none worked. The context menu - even though the handler is registered for the filetype - does not change or give the desired new options.
I am a local administrator, but I even wrote the GUIDs to the APPROVED section as described in M. Dunn's first chapter. Well, they still dont work, and I am pretty much *censored* since I can not get it to work.
I do have absolutely no idea what causes the failure, I did not change any of the example projects.
Can someone please help me?
Greetings from Germany

I create a mfc mdi app without doc/view.I meet a question.
I declare a int point member in cchildframe.
when I new(int) it in CChildFrame::OnCreate() or in Constructor,it does well.I free it in destructor like this
{
if(p)
{
delete p;
TRACE(_T("delete p\n"))
}
}
but if I new it in CChildFrame::PreCreateWindow(),it reports
detected memory leaks,instead I observer the trace message,I think I have delete it,but why error yet generated.I hope somebody can explain it to me.thanks
|

Memory leak means that there are non-freed memory after the app has ended. I think that the only reason is, that the framework calls PreCreateWindow more than once. Anyway, the PreCreateWindow is designed mainly to set the window class and you shouldn't initialize anything there
