November 30, 2004Nov 30, 200411/30/04I’ve seen some confusion over the difference between the GetKeyState function and the GetAsyncKeyState function.

November 29, 2004Nov 29, 200411/29/04The RunAs program demands that you type the password manually. Why doesn’t it accept a password on the command line?
This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts,
November 26, 2004Nov 26, 200411/26/04Here’s a tiny little program:
#include <windows.h>
#include <shellapi.h>
int __cdecl main(int argc, char **argv)
{
if (argc == 3) {
SHELLEXECUTEINFO sei = { sizeof(sei) };
sei.fMask = SEE_MASK_FLAG_DDEWAIT;
sei.nShow = SW_SHOWNORMAL; // added 27 Nov

November 23, 2004Nov 23, 200411/23/04Some people are offended by the special folders like “My Pictures” and “My Music” and delete them, only to find them being re-created. What’s going on?
Windows itself is okay with you deleting those folders. Some corporations, for example, remove those folders from their employees’
