Why use ReadDirectoryChangesW asynchronously?

I've read the documentation for ReadDirectoryChangesW() and also seen the CDirectoryChangeWatcher project, but neither say why one would want to call it asynchronously. I understand that the current thread will not block, but, at least for the CDirectoryChangeWatcher code that uses a completion port, when it calls GetQueuedCompletionSt...

Updating php version on windows with apache

I wonder what I should be carefull of updating PHP on Windows(with Apache). My current version is 5.2.9-2 My php folder is simply under C:\php If I simply download and unzip the new version, 5.3, which is a little more significant than going from 5.2.8 to 5.2.9, I'm thinking I need to be carefull not to overwrite some files.

I need to integrate an off-the-shelf Windows application with a Java application. At a few key points, I need the Windows application to send an "event" and some data to the Java application.

Convert System.Drawing.Icon to System.Media.ImageSource

I've got an IntPtr marshaled across an unmanaged/managed boundary that corresponds to an Icon Handle. Converting it to an Icon is trivial via the FromHandle() method, and this was satisfactory until recently.

Windows, Linux and Memory Management

I'm pretty curious about how Windows and Linux does memory management with C++ programs. The reason of this curiosity is because I've just made 3 very simple programs in C++ portable between Linux and Windows. The code was exactly the same. The hardware too. But the results were incredibly different! Both tests were repeated 10 times an...

Should I write a temp file to a temp dir? or write a temp file to the final directory?

When an application saves a file, a typical model is to save the file to a temporary location, then move the temporary file to the final location. In some cases that "move" becomes "replace". In pseudo code: Save temp file; if final file exists delete final file; move temp file to final filename; There's a window in there where ...

ASP.Net Strange Guids

An ASP.Net application we have recently developed is creating what I believe to be non standard Guids. The Guids are being created using the .Net framework method Guid.NewGuid(). Here are some examples of the guids created: 00000000-0000-0000-210f-0160000000f6 00000000-0000-0000-c02b-0160030000fc 00000000-0000-0000-ca2b-0160030000fc 000...
