Distribute the ReleaseMinDepdency build and you won't need any ATL or CRT DLLs. This is the preferred way since the situation with ATL.DLL is nasty (diff builds for 9x/NT, not 100% backwards-compatible)

I am trying to time a function so that when the function
completes I can get information regarding how long the
function took to complete a calculation. Currently I
am using this method:
<code>
clock_t start, finish;
double solver_time;
start = clock();
finish = clock();
solver_time = (finish - start) / static_cast<double>(CLOCKS_PER_SEC);
</code>
whereby I go on to report the time to the user by appropriately
dealing with solver_time.
Now, I am finding that for fast functions, this does't accurately
give an indication of the time (ie: sometimes it says 0 sec,
sometimes it reports a fraction of a second for the same
function as I presume I am reaching the accuracy limit of
the machine.
My question is: is there a better way of doing this?

You'll need a timer with a resolution less than 1 second. There is GetTickCount() which returns the time in milliseconds, however its resolution isn't 1 ms, it's dependent on a hardware timer. But give it a shot.

If you need really good timings, you can always use QueryPerformanceCounter. Not guaranteed to be implemented on all hardware/in all HALs, but I've usually found that it's available.
GetTickCount's resolution on Windows NT/2000/XP/2003 (bleargh, that's getting worse...) is dependent on the HAL installed on your system. I seem to recall that there's some way to modify what this resolution is, but can't currently find it.

Come on please anybody, I'm begging you! I'm certain someone has tried (done?) this before... please..

How can i make the dockable windows just like the Developer studio has?
|
|
|
|
|
|
I am using script control. when i add a procedure to the script control.if the procedure is error free then it works fine, but if there is a run-time error then a dialog box with the title "Just-In Time Debugging" and containg the option of .Net Studio that do you want to debug it. I want that this dialog box should not be displayed and i can handle this runtime error my self.

Hi! everybody:
I'm developing a ActiveX control which is a windowless, If I find something special in my class, I want to SendMessage to this ctrl and let it do something , but I can not get the window handle of this ctrl, so this ctrl also can not get this message.(I have tried AfxGetMainWnd, it doesn't work)
Does anyone has similar experience? Plesae give me some ideas, I'll appreciate
your help.
Ray

Hi,
As far as I know, it is not possible. Windowless ActiveX controls have no HWND by definition. Of course, COM passes RPC calls using thread message queue (in a case if the object belongs to a single-threaded appartment) but it cannot be simulated (and must not be).
The simplest way to handle it is to call a method of your control at the moment you need. The result will be exactly the same as with SendMessage - the control will process your call and return back. This will requre your caller class to hold an interface pointer to the control or provide it via a callback function.

I have a vector of integer that can have around 10,000 into it. There are cases when all the values in this vector are same. Right now i am just iterating through all the vector to find this out. Just wondering if someone can advise any better and optimistic way of doing this.

You can make use of a map to increment a counter for every time your data has a value.
map <int,int> g_mapData;
void insert(int val)
{
map <int,int>::iterator it;
it = g_mapData.find(val);
if ( it != g_mapData.end() ) {
it->second++;
}
else
{
g_mapData.insert(pair<int,int>(val,1));
}
}
And here is a test program
void main()
{
insert(0);
insert(10);
insert(5);
insert(0);
insert(5);
insert(0);
map<int,int>::iterator i;
for(i=g_mapData.begin();i != g_mapData.end();i++) {
cout << i->first << " , " << i->second << endl;
}
}
And the results are:
0 , 3
5 , 2
10 , 1

Thanks for the reply, But is there some way of doing this within a vector without adding another data structure.
|

Either keep the values sorted when they are inserted, or keep an index as the previous answer said. Without keeping some sort of index on the data, all you can do is a brute-force search.

If you want you can always add all items from the vector to the map only when you need to analyze your data.

Hi,
Ive been looking for examples of simple ActiveX applications (i have to convert an MFC program to an ATL one for a website. Instead of downloading an executable then running that file the dll is downloaded and the program is run off the website) and i cannot get my head round any of the resources ive found so far. Does anyone know a good place to start (with some simple examples)?
Thanks
