Check out GetLastInputInfo(). There's also the idle triggers when working with scheduled tasks.

You could retrieve the cpu times with a timer function and check what percentage of the increment was for the idle process.
The API for NT/2k/XP is NtQuerySystemInformation.

I have got an application, which changes the resolution of the computer(may sound like spyware etc... but it's just used internally).
The problem is that the Taskbar keeps flowing around in the middle of the screen. Is there any way to get a handle to the taskbar.
With Spy++ I found out that the WndClass is "Shell_TrayWnd". Does this help ?
As I said.. it's no adware / spyware or something I like that.. I hate those programs like we all do.

Use FindWindow() or FindWindowEx().

HWND hTB = ::FindWindow("Shell_TrayWnd", NULL);

Hi all,
I have a written a DLL that, during initialization, creates an instance of a dialog class derived from CDialog. This dialog contains a third party ActiveX control. If the DLL is loaded by an application, the creation of the dialog instance fails during the CDialog::Create method. If I remove the third party ActiveX from the dialog, everything is fine.
But, when I include the same ActiveX control into a dialog that is used in an application based on CWinApp rather than in a dll, it works perfectly well.
Any ideas?

Maybe you forgot OleInitialize()

That is dangerous because in a DLL, you have no control over what type of apartment your code runs in. AX controls are apartment-threaded, so if the calling thread is in a MTA, or never called CoInitialize() at all, you're SOL.
See this post[^] for more info.

Hi I am Mani Rajesh Kumar, working as Software Developer. I am currently developing an Image Processing Application
which deals with Large Amount of Data. I require as much as 2.5 GB of memory for my application. My System Configuration is
Microsoft Windows XP with Service Pack 1, 32Bit 2 GB RAM.
As we know By default OS allocates 2 GB memory for any single application.
I would like to know how to increase these 2 GB to 2.5 GB for a
single application.

In theory, the most an application could get from the heap is 2GB. But since it is highly unliklely that 2GB of contiguous RAM is available, the practical limit will be much lower. Certain OSs support a /3GB startup parameter, but even then there would need to be 2.5GB of contiguous RAM available. Why do you need so much all at once?

What about virtual memory? Although it would involve heavy thrashing, it is possible to allocate upto 2 GB without having that much RAM with the help of virtual memory. I think the 2 GB limit is because of the size limitation of some internal data structures in the OS.

You don't need that much contiguous RAM because the OS does distribute the data using the CPU's paging system. That means that e.g. 100MB of virtual contiguous memory doesn't have to be contiguous in physical memory. That is also a problem for hardware (especially DMA hardware)... see Scatter/Gather.
@manirajesh: Use /3GB as parameter for windows startup (boot.ini), that will enlarge the maximum user-mode memory to 3GB and decrease the max. kernel-mode memory to 1GB.

If you want to start an executable (or open a file) use this
<br />
HINSTANCE nResult = ::ShellExecute(NULL,_T("open"),strPath,strParameters,NULL, SW_SHOW );<br />
where strPath is your document or the path of your executable
and strPath are the parameters you may want to send to your executable.
