I can almost guarantee this is not how you want to organize this. What exactly are you trying to accomplish (that is, what is being done to the View that you think you want the Document to initiate it?)
If you decide to become a software engineer, you are signing up to have a 1/2" piece of silicon tell you exactly how stupid you really are for 8 hours a day, 5 days a week

there is no such API called GetDocument.
I again confirmed it from MSDN for my surety.
It is a member function of CView class

Isn't i know that.... GetDocument itself imply that it will retrive the pointer to the document class associated with view... isn't are anybody using WIn32 to simulate DOC-View architecture....i believe no..
and tell me what is MFC?.. a thin wrapper over win32!.
here what actual coding of GetDocument gives
_AFXWIN_INLINE CDocument* CView::GetDocument() const
{ ASSERT(this != NULL); return m_pDocument; } Actually many people here doesn't think what is api and what is funtion....
like for Example if you use FindWindow() it is api... and CWnd::FindWindow() it is function..
but if you refer them ... you will use this api or that api... what is api at end a function which providing
application programming interface

Actyally I have also some unix, Linux background.
And another matter is that I also studied many operatin systems.
And that all things tell, that an API is an
interface which an operating system provides to the outside
world. So in that context every direct function in an operating system
is an API. Actually an API provides an interface for applications programs.
And that way application programs can interact with the operating system.
And libraries comes at a second stage. These libraries also provides us ways to
interact with them, they sometimes also called APIs, but it is not an
approperiate word for that purpose.

this is not a good practice, You should not call a particular view from a document, because it makes document to depend on a specific view, And document view articture tells us that we may have multiple view,and documents so we should not make decument to depend on a specific view.
You can do so
1: call UpdateAllViews() from your document, with a hint.
2: this will call OnUpdate() in all views (if more than one)
3: in OnUpdate in your view class watch that specific hint and call that view class method you want to call

Hi,
I have a win98 system and I am in need of being able to read the partition table. I'm not sure if this is specificaly a c++ question, but I am writing the code in c++. I've looked up DeviceIoControl(...), which has a IOCTL_DISK_GET_PARTITION_INFO_EX control code. That would be awesome, except it is only supported in win2k/XP systems.
In win98 you have to use VxD and DOS interupt functions with DeviceIoControl(...). Again that would be fine, but I haven't been able to find an old dos int. that will give me the partition table. Does anyone know of one, or know a better way to do this? Thanks.

Hmm. From memory,
Int 13h is the Disk I/O one, and you'd want the first sector of the relevant disk, which should be where the MBR and partition table is.
ax = 0x0201
cx = 0x0001
dx = 0x0080 (1st HDD, 2nd = 0x81 etc)
es:bx is data buffer
CF (carry) set if an error occurred.
Disk sector should be 512 bytes.
Win9x might need you to 'lock' the volume using an Int 21h call, but I can't remember the details, since all this is so old....

I'm writing an application that grabs images from an IP Camera. These images are in the JPEG format.
I want to be able to display these images in an MFC dialog. It currently works using iPicture to load the buffered images and display them.
I want to try using GDI+. I noticed that GDI+ can load an image from a file. However, I can not find any references on how to do this with a buffer. Is this possible?
-- modified at 10:34 Monday 18th September, 2006
I forgot to add that I'm storing the image in a Byte Buffer.

Bitmap::FromStream works nicely
Look into CreateStreamOnHGlobal for how to get the BYTE buffer into a stream object (IStream interface)

hi,
i am getting the a debug error when i added it in the mainframe class oncreate() function.
Thanks,
Radhika.
|
|
|
|

Inside the frame window's OnCreate, you only need to call SetWindowText (no need to call AfxGetAnything...)
|
|
|
|
|
Hi,
I have just place the function like this in the oncreate() function , SetWindowText(_T("Radhika"));
But still i am not getting the required one.
Radhika.
