Hey man!
I hope that you don't take this too seriously. Actually, I knew Vivek was right right at his first message, but it was the eight year kid within me that was arguing for fun. But however, when I look at it all again, I feel bad because my contributions are recognized here and I've been awarded, which means people would expect a lot more from me than having funny chats. I realised it and felt bad. I am also feeling that I am a lot matured than what I was earlier, but then I know it that I still need to work even more on this. There's a very long way for me. I hope you'd wish me good luck. Because if I didn't know it, that was a different thing. But knowing it and doing funny things on a public forum is unacceptable. I'm sorry about it (to everyone). I'll try to keep my message standards higher.
I feel a lot relieved after posting this message. See ya.

Hey Rajesh
I respect your contributions here and I am truly glad there are guys like you who prove repeatedly that not all Indian devs are like the low-lives who post their work assignments here using sms-slang and expect people to write the entire code for them for free.
I did think your sub-thread with Vunic may have been distracting to the O.P. since he's a newbie, so perhaps it's best to avoid such humorous off-shoots in the technical forums.
Have a great weekend. Maybe you could go see Dashavatharam.

Use Richedit instead of smple Editbox. There you can add function on message EN_MSGFILTER. This permits filtering of mouse and keyboard message in the control.
TODO: The control will not send this notification unless you override the
CDialog::OnInitDialog() function to send the EM_SETEVENTMASK message
to the control with either the ENM_KEYEVENTS or ENM_MOUSEEVENTS flag
ORed into the lParam mask.
inside OnInitDialog mask the key events
m_rich.SetEventMask(m_rich.GetEventMask()|ENM_KEYEVENTS);
void CExampleDlg::OnMsgfilter(NMHDR* pNMHDR, LRESULT* pResult)
{
MSGFILTER *pMsgFilter = reinterpret_cast(pNMHDR);
CString buf;
if(pMsgFilter->msg==WM_CHAR )
{
buf+=pMsgFilter->wParam;
}
*pResult = 0;
}

Hi Masters!
I've an icon (with 3 dif. sizes, that's 16x16, 32x32, 48x48) in a DLL and I'm using it in an exe using DuplicateIcon() function.
The problem is that when exe runs, I expect to have 16x16 one on the taskbar button, but I'm just enjoying the 32x32 !
What can I do?

Add a message map entry...
ON_WM_ERASEBKGND()
Function declaration...
BOOL OnEraseBkgnd( CDC *pDC );

I would suggest to you, as a learning exercise to write a simple MFC application, may be just a hello world sample with some menu and some buttons "without using application wizard and class wizard".

Hi All,
I have a dll A which contains functions f1, f2, f3, and i use these functions in my application, say function f4 in my application uses them for some purpose, now the problem is dll A is from third party, and it can have multiple versions in the future?, how can i take care of this issue in my design of Application such that new version of this dll(new version may have more functions or changed function names) doesn't impact function f4, say if new version dll is just extension to previous dll, would it be automatically called by my app, or do i need to take some measure to support new version, please help by considering other similiar scenarios, if i have missed any?, Thanks in Advance!

If newer DLL is just an extension of old DLL then you dont have to worry about it. By extension I mean no existing functions were deleted, or changed - name or functionality. If newer DLL do makes some changes to existing function then it will break your code. Either way you can't do anything, except fixing you code when new new DLL comes. So stop worrying about it

Is there any way to set the paper size, say A4, and orientation in OnPreparePrinting() function which is called before the print dialog is displayed?
The problem is that I am not able to use CWinApp::OnFilePrintSetup function since the code is inside a dll and there's no class derived from CWinApp. So, in my own code for OnFilePrintSetup, I display a page setup dialog box and takes various inputs from user. Now, I want these changes to appear in print dialog also(which I get by using CVIew::OnFilePrint) and not the default settings that are displayed by print dialog box. So, the only way that I could find is to make changes to pInfo member in OnPreparePrinting but I could not get any way to set paper size. m_pPD member does not provide any way to set paper size?
Please help.
Thanks.

My problem is because of the fact that I am using my own dialog box for print setup but using the mfc provided dialog box for print. When I use my own dialog box, I dont update the internal m_hDevMode structure which has the information for all settings like page size, orientation, dpi etc etc.
I did not update because I did not know how to update and precisely speaking, i did not know about GetPrinterDeviceDefaults API.
This is what I needed to do to set the default settings before the print dialog is displayed. No matter what you do, you will always get a print dialog box with a4 & landscape set. It's sufficient for my purpose.
[code]
OnPreparePrinting(CPrintInfo* pInfo)
{
if(GetPrinterDeviceDefaults(&pInfo->m_pPD->m_pd))
{
LPDEVMODE dev = pInfo->m_pPD->GetDevMode();
GlobalUnlock(dev);
dev->dmOrientation = DMORIENT_LANDSCAPE;
dev->dmPaperSize = DMPAPER_A4;
}
return CView::DoPreparePrinting(pInfo);
}
[/code]
Thanks!

pInfo->m_rectDraw.top += (int) dTopOffset;
pInfo->m_rectDraw.right = (int) dRightMargin;
pInfo->m_rectDraw.bottom = (int) dBottomMargin;
}
I hope it helps.
EDIT: I made the change of orientation in the OnPrepareDC because I had a quite funny error. I had 5 different views, some on Landscape and some in Portrait. Every time I changed from "type" and printed, the first page was always with the last orientation used. Changing it there solved my error. There maybe is better place to do it, but it works :P
Regards.

thanks for the code.
I can see that you have modified the standard DoPreparePrinting code. But I am using the standard DoPreparePrinting code as it provides better error checking like what if CreatePrinterDC fails? your funciton will still return TRUE but not so in case of standard code.
also, I have not tried your code inside OnPreparePrinting but if you deleting the print dialog at beginning, then wont the settings entered by user in print setup box will be lost?
Say, you select A4 size in print setup box and when you go to print->properties, will it show A4 size selected or default size, probably letter selected?
And I am using the MM_TEXT mode throughout. Just adjusting the font size etc accordingly whether we are in print preview mode or displaying on monitor or sending to printer.
One weird thing I noticed is that if you are in print preview mode, then ::GetDeviceCaps (pDC->GetSafeHDC(), LOGPIXELSY) returns a different value from pDC->GetDeviceCaps(LOGPIXELSY) and the value returned by latter is correct one.
And dmPaperLength and dmPaperWidth were always zero although dmPaperSize was changing properly. I initially thought of storing length, width in a table but that would have been very very and very tedious. I found a better solution of creating a printer dc using
dc.Attach(pd.GetPrinterDC()); and then you can obtain paper length and width from dc.
I have not still tried multiple pages, so cant say if there can be problem with that.
the fruits of your success will be in direct ratio to the honesty and sincerity of your own efforts in keeping your own records, doing your own thinking and, reaching your own conclusions.

First of all, thank you for your comments. They have make me notice some things I can improve in my code
theCPkid wrote: the standard DoPreparePrinting code as it provides better error checking like what if CreatePrinterDC fails? your funciton will still return TRUE but not so in case of standard code.
Yes, you are right, but you can add that error checking all the security you want/need before returning TRUE. (I will change it)
theCPkid wrote: but if you deleting the print dialog at beginning, then wont the settings entered by user in print setup box will be lost?
No. You are right, I am deleting the standard CPrintDialog, but changing it with my CDlgPrinting that is derivation of it (I actually made a copy of the standard and modified it to fit my needs), so it has the support for print-setup as well.
theCPkid wrote: Say, you select A4 size in print setup box and when you go to print->properties, will it show A4 size selected or default size, probably letter selected?
The trick is that I have no "print setup" in the main frame menu, it has to be made through my dialog if you don't want to print with the standards (A4, portrait, black and white). I made a test in a plotter and it was successfull with A4 and A3, I don't allow smaller pages because of my application's workspace. I print graphics, tables and other things, needed info wouldn't fit otherwise or, I have to zoom it out it would be too small to be clearly understood. But I restrict some setup because of depending on where is being printed it "must" be printed with some specifical configuration, so I give it "manually" in the code of the view.
theCPkid wrote: Just adjusting the font size etc accordingly whether we are in print preview mode or displaying on monitor or sending to printer.
Why? I am using the same font for both and it works good. I create them with:
CFont fontLabels, fontInfo;
fontLabels.CreatePointFont (80, "MS Sans Serif", pDC);
fontInfo.CreatePointFont (140, "MS Sans Serif", pDC);
theCPkid wrote: And dmPaperLength and dmPaperWidth were always zero although dmPaperSize was changing properly. I initially thought of storing length, width in a table but that would have been very very and very tedious.
I don't use it because I directly work with the pInfo->m_rectDraw it makes it more portable (I think, but maybe I am wrong). Its dimensions change automatically with the change of paper size or orientation by print setup. In my case I want to use A4s for the info pages (both portrait and/or landscape) and I allow an A3 for the project workspace. I do it dinamically in my CDlgPrinting disabling some options according to which view called it.
Once returned I modify the pInfo->m_rectDraw according to orientation and paper size in each view thanks to the "offset" I calculate at the beggining of OnPrint. The only thing I don't like is the repetition of the calculation on every page. I will change it in future versions.
I whish you good luck and success with your printing code, let me know about it when you are finished. I'll like to have other perspectives
Regards.
