Is there a way to get notified about system shutdown or restart?
In which way will an application be terminated when shutting down?
|
|
|
|

There are two Way for Knowing System is Shutting Down
First Easy Way
When ever system shutdown ,it send WM_QUERYENDSESSION all opened Application notifying system is shuting down.
Second Little tough way
Write a WinLogon Notification package,that will notify you about System Shutdown and much more.
you can Find a Very Good article on CP MFC/C++ /SYSTEM section over Winlogon DLL

WM_QUERYENDSESSION seems perfectly fitting for me.
Thanks, Alok

Is there a way to trap certain keystrokes from an application, even though its window does not have the focus?
My goal is to make an application almost totally invisible (except in Windows Task Manager), i.e. the main window is hidden, task bar button removed, Alt-Tab does not show it - but somehow I have to activate it from time to time, i.e. I need a kind of shortcut.

Let i take your goal one by one.

Make a Dialog Box application with WS_EX_TOOLWINDOW Style (that remove button from taskbar and doesn't respond to ALT+tab message)
and Start your window in hidden mode.

u can use HOTKEY for that when ever a special key combination occur activate the window (look for RegisterHotKey api in MSDN)

Making the window invisible was not a problem, but thanks anyway. Btw, you don't need WS_EX_TOOLWINDOW while the window is hidden, for the task bar button disappears, and the application does not come up with Alt-Tab (even the task manager does not show it as an application, only as a process). However, you need WS_EX_TOOLWINDOW if you want the task bar button disappear, etc. even while the window has the focus.
Re HOTKEY: this gave me the hint, and I looked for it (earlier I was looking for "shortcut" and did not find anything useful).
I found an alternative solution too: WM_SETHOTKEY. I will evaluate, which way is better for the particular situation.
Thanks, Alok.

Hi,
I have implemented a game that adds nodes to a list; in essense it is creating a tree. When I add a node to the tree, I use malloc to create memory for the node and push it onto a stack. I then pop it from the stack and do a check. If the check passes I push it back onto the stack, if it fails, I want to delete the node so I use free() to free the memory that was created for it. What is happening when you look at the Task Manger in Windows (XP), it shows the memory being allocated and freed for the application, but when you look at the field called "Commit Charge" within Task Manager, it shows a constant rise in the amount of virtual memeory being used. This continues to grow until the program ends with a memory allocation error. My question relates to resources/links/recommendations on how to better handle memory within a C++ program. I am using Microsoft VC++, version 6.0. I've looked through the code for memory leaks, but it it appears to do as it should; allocating and releasing memory in the proper order. Since it appears that memory leaks is the cause, I am looking for links or recommendations on how to find these leaks.
Any recommendations or resources would be greatly appreciated.
Thanks in advance.
Martin

My first question would be why are you not using the new and delete operators?

Well the first thing you should do is get a memory validator program that checks for resource leaks. There are several out there, I use Bounds Checker but I sure one of the others would work just as well. It has been a while since I visited any of thier sites, but they usualy offer a 30 day free trial that you can download, so it is well worth trying.
If the nodes of the tree are actualy class that allocate memory, you could be leaking it there. Since malloc and free no nothing about destructors and therefor will not call them, use new and delete instead.
You could also try using the memory validation functions in the SDK, they require adding additional code to your program inorder to use them, but I understand they work quite well. I beleive there is at least one article at CP some where, on this subject.
Good Luck!

I have a USB disk and know its Vendor ID(VID) and Product ID(PID). Perhaps this USB disk has several partitions. Here is my question which puzzled me so long: How to get the volume letters through the known VID&PID?
Thanks a million.

hello i just migrated from msvc6.0 to .net now im trying to work on an mfc project i had however i am not able to find anything like the mfc class wizard, i figured out how to add new vars but as far as events and viewing and modifying old variables via the class wizard i dont know what to do is there a central wizard type or have they completely removed that feature?

i found how to add a new class to a dialog but as far as modifying the current one im lost
thanks

The classwizard has been radically modified for VS7/7.1. Most of the events and handlers can now be accessed via the properties controlbar.
see this

I want to use the colorful tree structure icon in my app. But its index is
84 in shell32.dll on win2k and 78 on win98. So what's the CSIDL for it?

I'm trying to use the windiff feature to compare two source code files. I'm not sure where this gets invoked though.
If I just enter it in a Windows command window I get "windiff is not recognized as an internal or external command, operable program, or batch file".
If I bring up a command window in Visual Studio via the View->Other Windows->Command Window menu option and then type windiff in there I get "Command windiff is not valid"
If I run the MSDN Library program and try to find a command window there to invoke windiff, I can't seem to find any way to bring up a command window.
What am I missing here?
