First step is to tell us where it crashes, otherwise we are just guessing.

In the MessageBox:
File: winctrl2.cpp
The Debug makes the error in this function:
extern "C" int WINAPI
_tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPTSTR lpCmdLine, int nCmdShow)
{
// call shared/exported WinMain
return AfxWinMain(hInstance, hPrevInstance, lpCmdLine, nCmdShow);
}

Create a new DOMDocument object called say xdoc. Add nodes to the XML tree of the type IXMLDOMNode, and then call doc.xml to return the XML as a string.
There are a few articles on CP showing you how to #import and make use of the COM objects.
MS have provided two XML parsers. The DOM parser, and the SAX parser. The DOM parser basically does what its told as its just a series of objects and calls to manipulate them, where as the SAX paser is event based which can make it quite useful for parsing big documents in a distrubuted environment.

For creating high performance socket server, we use the technique of IO completion ports. We create IO completion port and related threads ourself using the function CreateIOCompletionPort().
There is also another function called BindIOCompletionCallback(). If we use this function we don't have to do the manual work. We simply let windows to create IO completion port and associate threads with it.
My question is that which solution is the more efficient, either manual creaton of IOCP or the later one.

what is the difference between Berkely sockets (Winsock2) and IO completion ports?

It sits on top off.
IO Completion ports are a WinNT feature that relate to all IO from disk access to Sockets. Basically you can use a limited number of threads to manage a large pool of connections at the same time while IO is pending.
Say 5 threads for 1000 connections is not unheard of. Because your not using a wasteful thread per connection with all the thread context switching goind on as the system scheduled them, then you get better efficiency, and the system is less likely to run out of resources, and suffer a denial of service attack. It helps get a lot more out of IO features on Windows which is useful for servers.
Read these to get a better feel.

Also if you can get hold of a copy read Programming Server-Side Applications for Windows 2000 - Richter - MS Press. Has a good example of using them for searching files on the hard disk at a blinding speed.

This is only avaliable on Windows 2000 and later. If you need to support WinNT4 then you cannot use this as NT4 cannot manage the thread pool for you.

Handle NM_CUSTOMDRAW. You can change colors and button styles in response to that message - see the MSDN docs for the full list of capabilities.

Hi,

rect(360, 420, 240, 280). Is there a simple method to do this?
Best Regards,

BitBlt and StretchBlt both allow you to specify the part of the image to draw.

it depands speed u need for drawing.
1. if need high speed, u have to draw it from file buffer, in the case, u need to know bitmap format, it is not too hard, but hard to draw because all DC functions are nor available.
2. create a memory DC, display bmp file on it, then draw it with DC functions. if u want to change ur file, save it according to ur memory DC.

I have a class which can calculate a mathematics expression,such as "sin(x)+cos(x)",when given a number to x, it could return the value of the expression.It works in two steps:At first,it parses the expression,and then,it calculates.I have a list of x's values,all of them are used in the expression "sin(x)+cos(x)",so they are calculated in the same way,but the class parses the expression for each x value,you see, it does the same work many many times.What can I do if I want the class to parse once but calculate all?

Make a static array, which is a lookup table. Then each sin or cos is calculated exactly once.
