Windows 7 gave us some nice and useful little eye-catchers in the taskbar. Those are available using the Windows shell interfaces ITaskbarList3 and ITaskbarList4. But alas, how can a Delphi developer incorporate these in his applications?

This article is about how to retrieve the owner of a file. If you are experienced with some of the WinAPI security function this can be pretty easy. There are some problems that needs to be addressed though. The first one is the size of the security items like the SID name of the owner. [...]

In my last article “Jwscl and FreeAndNil” there were some great comments on the source design. Oliver told me to use a guarded memory page so the memory is always invalid. With his information I wrote a source code that creates a pointer which always triggers an access violation.

If you look at the MSDN documentation of CreateProcess you might notice the following remark for the lpCommandLine parameter: The Unicode version of this function, CreateProcessW, can modify the contents of this string. Therefore, this parameter cannot be a pointer to read-only memory (such as a const variable or a literal string). If this parameter [...]

However the FTP server is empty and so all the links are invalid. Luckily, you can find the most recent versions in [...]

Locally we can use the GlobalMemoryStatusEx API but there’s no API to do this remotely. It would be possible [...]

Recently, I’ve found a bug in JWSCL. It happened that the function GetInheritanceSourceW didn’t work for me anymore. A long time ago I used this function for the last time and now again. However the strange thing was that the function returned no error but it didn’t fill a result array with expected inheritance data. [...]

A couple of days ago I finished a first beta of my tool TSAdminEx. If you don’t know what TSAdminEx is let me briefly introduce it: TSAdminEx is a tool that combines functionality of several existing tools: it has the power of task manager combined with the details of Process Explorer and the Terminal Server [...]
