using BitMlt:
CRect rect;
this->GetWindowRect( &rect );
this->GetParent()->ScreenToClient( rect );
CBitmap img;
CDC dc;
BITMAP bmp;
img.LoadBitmap(m_nImageID);

dc.CreateCompatibleDC(pDC);
CBitmap* pOld = dc.SelectObject(&img);
pDC->BitBlt(rect.left, rect.top, bmp.bmWidth, bmp.bmHeight, &dc, 0, 0, SRCCOPY);
using Image::DrawImage
CRect rect;
this->GetWindowRect( &rect );
this->GetParent()->ScreenToClient( rect );
m_img = Gdiplus::Bitmap::FromResource(GetModuleHandle(0),MAKEINTRESOURCE(nImage));
grpx.DrawImage(m_img, 0, 0, m_img->GetWidth(),m_img->GetHeight());

What are the values of rect.left and rect.top in case 1?
The best things in life are not things.
|
|
|
|
|
left = 50 and top = 50 in both cases
|
|
|
|
|
Fine, but in the second case you are drawing at Point(0, 0)!
The best things in life are not things.
|
|
|
|
|
grpx.DrawImage(m_img, 0, 0, m_img->GetWidth(),m_img->GetHeight());
why don't you try using same rect.left and rect.top instead of 0,0 in drawimage??

Gopinath.

the problem of mine is: I defined four document templates "A B C D" in my program and I set the document template "A" as master document template others as slaves.that means I use the master document template to open data and transfer data to other document templates. so I only implement the OnOpenDocument() function of the master document template. after I have finished all the framework. my leader tell me that the view from the "B" document template should be display firstly or on top after the data is opened. so I have to hide the view of master document template and show the view of slave "B" document template. but I found the "B" is not activate, that means all the menu or toolbar command message loop are still clue to master document template. please tell me how to active the B document template and let it to response all the menu commands.

LPCTSTR password = _T("1234");
zip.Open(sar,CZipArchive::zipCreate);
zip.SetPassword(password);
zip.SetEncryptionMethod(CZipCryptograph::encWinZipAes256);
zip.AddNewFile(filepath);
zip.Close();
// TODO: Add your control notification handler code here
MessageBox(_T("file is locked successfully"),NULL,MB_OK);
when i see in winhex its shows the which type of file and data ...

For merging together some recording data stored in CSV files I have used the class CtextFile (by Johan Rosengren via the Codeproject site) to read in and write out the processed files. I also used class CNewStringArray (which is a modified version of CStringArray by Anders M Eriksson, again via the Codeproject)
I use the MFC function AfxExtractSubString() to extract the various fields of the CSV record and CnewStringArray variables to hold and process the data.
Now I have a problem where the size of some of the files to be processed may be in the order of 250 to 700Gb.
I have never used files larger that about 10Mb, but will I have problems with files these sizes and do I need to consider new methods of processing these very large files.
Any comments and advice please.

I'm not an expert on that topic, but I think you have to look at Memory Map Files.
That will let you navigate the file without having to load the whole file in memory.
Watched code never compiles.

Yes, you definitely are better off using memory mapped files,
namely, you should use "CreateFileMapping", "MapViewOfFile", "UnmapViewOfFile" and the likes.
It is a bit outdated, but the book from Jeffrey Richter
"Programming Applications for Microsoft Windows" has a good introduction to such an API.
Maybe, looking into MSDN with these pointers will lead you to the correct API to use
for your Operating System version.
Cheers
Federico
yeap, it is still the same API in latest versions of Windows, just checked on MSDN:

Thanks Federico for your post.
I have used these API's, but for large auto generated data structures ~ 50k bytes.
I did look at he link you gave and the following concerns me:-
If the file mapping object is backed by the operating system paging file (the hfile parameter is INVALID_HANDLE_VALUE), specifies that when a view of the file is mapped into a process address space, the entire range of pages is committed rather than reserved. The system must have enough committable pages to hold the entire mapping. Otherwise, CreateFileMapping fails.
With files sizes of ~ 500GB will these APIs work?
Andy.
