I am opening a file from network drive location. During file read, the mapped network drive is disconnected, my application get crashed and closed. how to check the mapped network drive is connected or not using file pointer.
case 2: during file read, I am disconnecting and connecting the mapped network drive that time pointer is not null. but I cant able to access a file using this file pointer.
I want a code of c code
which can take million integers as input,
sort them (bubble or quick or selection sort).
It should display time taken to sort first 10 integer, then for first 100 integer, then for 10000 and total.
Please help me soon I have very less time to complete my project.
Well then, you'd better hop-to-it and get writing then don't you?
There's countless examples of sorting code on the web. If you cant even be bothered to search for them, and instead ask to be spoon-fed,you're not going to enjoy programming much - it's an occupation that required copious amounts of research.

"When I was 5 years old, my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down 'happy'. They told me I didn't understand the assignment, and I told them they didn't understand life." - John Lennon
I am trying to get all available logical drive information using WMI services. If a partition is under extended partition, I am getting wrong startingOffset although getting correct startingoffset in case non extended partition.
The assert fails because the CWnd* does not point to an object that contains a valid Window handle. Something in your code has not been initiailised correctly, or you are calling Create from outside of a Window class. What class is Show_storage?
CMFCPropertyGridProperty* level1Group = new CMFCPropertyGridProperty(_T("Level1"), 0, TRUE );
CMFCPropertyGridProperty* subLevel1 = new CMFCPropertyGridProperty(_T("subLevel1"), _T("subLevel1"), _T("subLevel1") );
CMFCPropertyGridProperty* level2Group = new CMFCPropertyGridProperty(_T("Level2"), 0, TRUE );
CMFCPropertyGridProperty* subLevel21 = new CMFCPropertyGridProperty(_T("SubLevel2.1"), _T("SubLevel2.1"), _T("SubLevel2.1") );
CMFCPropertyGridProperty* subLevel22= new CMFCPropertyGridProperty(_T("SubLevel2.2"), _T("SubLevel2.2"), _T("SubLevel2.2") );
CMFCPropertyGridProperty* subLevel23 = new CMFCPropertyGridProperty(_T("SubLevel2.3"), _T("SubLevel2.3"), _T("SubLevel2.3") );
I tried inheriting my own CMFCPropertyGridProperty class and overwrite the OnDrawName but because of many protected members in the base class. (see CMFCPropertyGridProperty::OnDrawName in afxpropertygridctrl.cpp )
Now, I did overwrite the OnDrawName method, but removed lot of code that was in the base method that did not compile (access to protected members); but it seems to be OK.
As is well known when using switch (expression), thus:
"The expression must be of an integral type or of a class type for which there is an unambiguous conversion to integral type".
If the switch contains a number of case / 2 to 4 /, then there is no problem.
Well, if you say case is 30 pieces, then dostura to 29 in a row case, the compiler must make 29 comparisons.
Below is a one of the solutions to this problem.
And so the program as expression must transmit the index number to any array, containing the address points
transition operator goto.
Notes: Of course array must contain the called function.
Have a gander here[^]. Pay particular attention to #11.

I'm developing a simple tracking game using two haptic devices as controllers.
Haptic rendering is executed in a high priority thread.
During the experiment, force experienced will depends on the position of each player, it's calculated as follows:
I have 100 trials of tracking tasks and I have to calculate the average interaction force during each trial. How it can be done? my issue is: this manipulation have to be done in a thread with execution rate of around 8KHz
Thank you!. I have already seen some implementation of moving average. But I'm not sure about how to implement for my application. Since it's in a thread which is executing at 8Khz, I'm wondering how to store forces trial by trial and to take avareage?
The fastest solution would be a ring buffer and a total sum variable (untested):
int items = 0;
int ndx = 0;
// May need floating point here when max. value * buffer_size >= INT_MAX
int sum = 0;
int get_av(int val)
if (items >= buffer_size)
sum -= buffer[ndx];
sum += val;
buffer[ndx] = val;
if (++ndx >= buffer_size)
ndx = 0;
return sum / items;
This should be fast enough for your requirements
