May 31, 2013May 31, 201305/31/13Regardless of
which interpretation you use,
it remains the case that posted messages
are processed ahead of input messages.
Under the MSDN interpretation,
posted messages and input messages all go into the message queue,
but
posted messages are pulled from the queue before input messages.
May 30, 2013May 30, 201305/30/13There are multiple ways of viewing the interaction between
posted messages and input messages.
MSDN prefers to view posted messages and input messages as
part of one giant pool of messages in a message queue,
with rules about which ones get processed first.
May 29, 2013May 29, 201305/29/13The SecureZeroMemory function zeroes out memory in a way that the compiler will not optimize out. But what’s the point of doing that? Does it really make the application more secure? I mean, sure the data could go into the swap file or hibernation file,
May 28, 2013May 28, 201305/28/13You can set a hotkey on the shortcuts in your Start menu, and Explorer will launch that shortcut when you press the hotkey, but not if you are in a fullscreen application, like when you set Paint into fullscreen mode, or when you are displaying a PowerPoint presentation.
May 27, 2013May 27, 201305/27/13I dreamed that I had to fix a bug caused by variable redeclaration inside a nested courtyard. Had to move the horses out of the way first.
And then it got weird.
I won’t go into the orchestra rehearsal that turned out to be just a recording played on a loudspeaker in an empty concert hall.
May 27, 2013May 27, 201305/27/13You already know how to create a shortcut:
#include <windows.h>
#include <tchar.h>
#include <shlobj.h>
#include <atlbase.h>
// class CCoInitialize incorporated here by reference
int __cdecl _tmain(int argc, TCHAR **argv)
{
// error checking elided for expository purposes
CCoInitialize init;
CComPtr<IShellLink> spsl;
May 24, 2013May 24, 201305/24/13As we well know, the window manager generates various messages on-demand rather than posting them into the queue at the time the event occurs. But what happens if you manually post one of these messages, like PostMessage(hwnd, WM_PAINT, 0, 0)? Does that clear the internal flag that says “This window needs a paint message?”
May 23, 2013May 23, 201305/23/13We all know that the generated-on-demand messages like WM_MOUSEMOVE, WM_PAINT, and WM_TIMER messages are not posted into the queue when the corresponding event occurs, but rather are generated by GetMessage or PeekMessage when they detect that they are about to conclude that there is no message to return and the generated-on-demand message can be returned.
May 22, 2013May 22, 201305/22/13Some time ago, I showed how to get a window back on the screen when it moved far, far away. That technique still works in Windows 7 and 8, but there’s an easier shortcut that takes advantage of window arrangement features added in Windows 7.
May 21, 2013May 21, 201305/21/13On an internal mailing list about home maintenance and ownership, somebody asked:
I have a handful of items that I need to get rid of and probably should not toss into the regular garbage. Any thoughts?
Older TV — 32″
Propane tanks (full)
Lighter fluid
Carpet glue adhesive
Lawn fertilizer
The best reply was an unhelpful one.
