Hardware timer on an embedded device...
Seriously, if your requirement for determinism is at all strict [*], a general purpose OS like windows is not for you.
The nearest I'd say is some sort of device driver (you don't actually need a device to write one) using waitable timers. But even then, you'll get jitter.

[*] You said "very accurate". Being an engineer, I'm assuming you're not exagerating.

Hi,
i want to get number of printers attached to my computer, i use Win32_printer class to get the printers, but before connecting WMI i impersonating to some other user. But the WMI gives the output not for the impersonated user but the one who has launched it.
I am launching the process in system accout and trying to impersonate to the logged in user to get the printer information of the logged in user. (Initially i have to launch the process in system account) Does anybody has any idea how to do this??

Check why the Impersonate to other user is not successful.

Hello friends,
I've a MFC Extension DLL in which it declares the shared variable as below
in .cpp file I have code as below
#pragma data_seg(".adshared")
int count=100;
#pragma data_seg()
#pragma comment(linker, "/SECTION:.adshared,RWS")
I've the method to get the value of count variable
bool Getvar2(int *p)
{
*p=count;
return true;
}
in .DEF file I have the code as below
Getvar2 @1
count @2
In the client application I've tried the code as below
1)
int *i;
i = (int*) GetProcAddress(m_hDLL, "count");
2)
//FunPtr2 is typedef bool(*FunPtr2)(int *p1);
p=(FunPtr2)GetProcAddress(m_hDLL,"Getvar2");
if(p(v))
{
}
In both the above cases the program crahsed when I try to access shared variable of the MFC Extension DLL.
How can we access the shared variable from the client application?

Have you checked p value?

Thanks for the reply,
yes,I've checked the value of p and it contains the valid value.
The access violation occures at the next line after p has been intialized.

How v is declared?
Why don't you use accessor methods (i.e. int getCount(), void setCount(int x))?
Have you made a test with a not-shared variable?

How about creating a game called "LIFE" that we all are playing. It should be simple enough.
Somethings seem HARD to do, until we know how to do them.

Are you sure that's not 14031?

Where do you get that? MSDN states:
ERROR_INTERNET_CONNECTION_RESET
12031
The connection with the server has been reset.

Hi Friends,
please reply ......
Windows Vista provides a slider control to resize icons ( thumbnails) in My Computer Explore view.
I need such resizing in my Windows XP application. Please provide what should be the logic to achieve the things smoothly.
One solution that I think is:-
1) create and delete the ImageList of current view as user resizes but overhead of creating and deleting is very high.
I need smooth resizing.
Any help is highly appreciated.
Thanks in advance.

Why don't you draw the image scaled with some Image Drawing API that draws scaled like GDI+ DrawImage, StretchBlt, ...
