It depends on what the type of image file it is.
Normally the width and height is stored in the header, i.e. the first few bytes of the bitmap file.
To find out about file formats see http://www.wotsit.org/search.asp?s=graphics[^]
So all you do it read the first few bytes of the file.

yes. you can learn how to parse each of the different file formats to find out how and where each format stores image size information.

1. Does AcceptEx and ConnnectEx support IOCP?
2. Mswsock.h doesn't have a declare of ConnectEx, how can I use it?
3. If A sends a packet to B, then B receives it use in an IOCP method, but how does B know when to call WSAReceive? DO I have to use WSAAsyncSelect/WSAEventSelect at the same time?

Hi,
1. Yes, and yes.
2. U should be using winsock2.h
3. IOCP sockets that support 'receiving data', should be in a constant state of 'being ready to receive data. Due to the nature of IOCP, the worker threads are the ones handling the events, so you don't want to use WASAsyncSelect/WSAEventSelect stuff.
There are a couple of really good articles on CP for IOCP servers and sockets - you should have a look at them. Also, remember that if you have multiple buffers per socket (which you should have), you will not always be able to guarantee the sequence of partial packets received when you run on a multi-CPU box.
Hope this helps a bit

You can use html tags in your name:

Why not just right-click his name, and select View Source from the context menu?

I want to change the caption of the button in a property sheet. I have use the following code to get OK, Cancel and Help button,
MyPropSheet.m_psh.dwFlags |= PSH_NOAPPLYNOW | PSH_PROPTITLE ;
MyPropSheet.m_psh.pszCaption = "Simple";
Now I want the caption of the OK button to be "Submit" or "Go"... How to change the caption?

Use this code:
GetDlgItem(IDC_YOURBUTTONID)->SetWindowText("Text");

The problem I am facing is button is not created by me, so unable to get the ID. Its the default button of property sheet. (Just like the OK button in MessageBox).. I have tried the same code with a button ID IDOK but its not working.
|
|
|
|
|
Try out EnumChildWindows(Provided that the property sheet doesnt have many child controls) then check for the text if its the one you want to change then change the text of that control with your one.
