Re: Help regarding DeleteFile(..) - C / C++ / MFC Discussion Boards

Are you closing the created/opened file before trying to delete it?

YES iam closing the files(fclose).
and more over, the files were created in previous sessions. not in the session where iam trying to delete them.
and my files have the extension .cry does it matter?
here are some case studies.
1.iam trying to delete the s1.cry(created by my application) like this
filename="s1.cry";
DeleteFile(rootpath+"\\cryfiles\\"+filename);
RESULT : no use.
2.now i rename it through windows like s1.cry1 and
filename="s1.cry1";
DeleteFile(rootpath+"\\cryfiles\\"+filename);
RESULT : successful.
any ideas?

I make it like follows:

void CMyView::OtherFunction ()
{
	char FileName[MAX_PATH];
	GetModuleFileName(NULL, FileName, MAX_PATH);
	m_szOfflineName = FileName;
	m_szOfflineName = m_szOfflineName.Left(m_szOfflineName.ReverseFind('\\'));
	m_szOfflineName += "\\OfflinePCode.pc";
}
.
.
void CMyView::OnDestroy() 
{	CFormView::OnDestroy();

	CFile f;
	
	//The offline PCode is not needed anymore
	if (f.Open (m_szOfflineName, CFile::modeRead))
	{	f.Close ();
		f.Remove (m_szOfflineName);
	}
}

But I am in MFC, I dont know if u can use the CFile

even this logic didnot work for me.
but this gave me some clue to proceed further.
if it works out i shall share the problem and the solution here with you.
thanks a lot.

and by the way Nelek,
could you solve the scroll bar dialog problem?
thank you.

To be honest... I have not tried more than what I told you. Im in a new project and my time for VC++ is limited. I will take a look this weekend at home. But it actually won't be so easy. I can not simulate your problem, my scrolls are working ok.

thanks.
i shall wait till weekend.

If there is more info about the problem than what you already worte in the other post, please send me the relevant codes and a explanation about. You can use the private message if you want.

Hello All,
i have a bmp file which created by the application and now i want take printout of this bmp file through programming.

i am unable to send this bmp to printer so please give me some how can i take printout.

thanks

Printing is not so easy to be just told here.

Start reading in the Print area of the website and post when you stuck with some code.

To print you will need use a DeviceIndependantBitmap (DIB) with the palette and so on, to ensure printing in as much printers as you can. Watch out with the MAPMODE and the coordinates, they may not be compatible with screen and if u take methodes from other places, what works in one side, here won't.

Nelek, would you give some links to learn print?
I want to print contents of my CListCtrl.
Thx first.

See Printing Architecture[^] but do you want to print the picture?

Hi,

to print bitmap, I usually use the StrechtBlt ().

to print CListCtrl... I am not really sure if there is something that automates / makes it easy to be printed. I printed the CListCtrl table by hand. Making the lines and writing the contents using "for" and other things.

I recommend you to read the articles about printing by Roger Allan, to begin introducing yourself in printing are quite usefull, but there are aspects that are not commented in them.

You can use of BitBlt with a handle to dc of printer.

Personally I prefer to use StrechtBlt in printing jobs. Main reason is that usually the size of the view is not the same as the printing area, so zooms may be needed.

I have loaded image in picture box

It's displaying in center. It gets reduced in size in picture box.
So I need to calculate the reduced size in picture box as image is displayed in center of picture box.

how can I calculate that?

You could use GetClientRect() on the picture box.

Did you use of StretchBlt?

I am not able to find the NM_CUSTOMDRAW message in messages. How to add this message handler to the project?

You won't get WM_CUSTOMDRAW message for all the controls.. and also to customize the control you have to derive your own control class from the control base class
