I wanted to find out the total bytes sent out by IIS virtual website. there are performance counter support in c#
like System.Diagnostics.PerformanceCounter
which works fine. But the problem is, if that site is restarted (directly of by iisreset or a machine reboot) the counters are reset to zero. Is there a way to cacth an event that the counter is reset to zero and read the value just before it was reset to zero?

Couldn't you just remember the last value you got? Then when the counter comes back as zero, you can substitute the last value which you have stored already.

Yess, but its not a perfect solution. lemme explain why
say the counter was 200 when I sampled the value and stored it. Then the counter was increased to 250 and suddenly reset to zero. and then it grew to 100 before the next sampling happens. So I have lost 250-200 = 50 bytes.
Unless its event driven, I have to sample it at regular interval. And all the ups and downs withing my sampling window are not trapped. WMI is a resource consuming thing and not advisible to run it frequently.
Probably I can do away with the missing values withing the sampling window but is there a perfect solution? Instead of sampling If I am notified when the counter is reset to zero with the value it had just before it was reset, that will be the best possible solution. What do u think ?

I'm not sure what exactly you're trying to do. You can use a performance counter at a relatively small interval (every 1 or 2 seconds), which will likely avoid your missing bytes problem. In fact, that's exactly what the performance monitor app which comes with Windows will do. Yes, these are related to WMI, but I don't see any significant resources being used with a single performance counter.
I don't know of an event that will give you what you want, but if the neither the WMI docs nor the IIS docs describe such an item, it's probably not there.

May I ask if anyone got the experience on creating skinable or non-regular form with C#?
|
|
|
|
|
I have ...
im creating a form skinner right now.
it works quite good , im overriding the wm_ncpaint (and other related messages) to draw the form border and caption.
currently im using gdi+ but will upgrade it to old gdi32 since gdi+ is horribly slow..
the stuff i have left to do is:
make it work 100% with mdi forms...
make it use layered windows for transparency instead of regions.
make it draw the attatched menu (the menu is otherwise drawn at the default location ,which might be inside the caption if using a larger caption than normal)

is it possible to get the name of each Component created in my form and intialized from a System.ComponentModel.Container. I created a console app for my program that runs through command line args...i want to dump the names of each component on the form (the code name for the component) to this console. possible via a foreach statement. Please write me back in reguards. i can always go through and just write the names manually but it would be easyer if i could do it with a foreach statement... thanks alot

It sounds like all you need is to do something like this:
foreach(object o in container)
{
string itemTypeName = o.GetType().ToString();
}

i just recently got a loan finally for school and im starting some MCSD classes here in washington for a hopefull good start in C# and programming. after im done with this schooling they set you up with a job and such. but my question is what do i do after i get my MCSD ? where else do i go for schooling.. how can i be competive in the Software Development field.. i know alot of people in this class are all from C++ backgrounds...not me though i never wrote more then a Hello world app in C++ but in C# i have reflection and just about everything i can think of i can do (if i cant... leppie is here too help me ).....can i still be competive in this field even without knowing much about C++ ? thanks for your time

Learn to program ? MCSD classes are likely to be somewhat of a waste of money IMO. You should buy some books, lock yourself in your room, and learn.

I started teaching myself C++ at home and had a job in six months, three years ago. So I'm all for teaching yourself and working hard.
jtmtv18 wrote:

It seems obvious to say this, but unless the job is C++, why would you need to know C++ ? For all that, I'm teaching myself J2EE at the moment, you can't know too many languages/frameworks. I do all ASP.NET at work.

yeah i started teaching myself C# about 6 months ago when i got in my motorcycle accident..(ouch) i love it. but im only 19 so i figured....having a MCSD would help me out more..and let me be taken more seriously... i mean hell i was a cook before my accident...i new macromedia and javascript lol.... but my passion is programing. and when i look at C++ it seems to look easyer to me now after C#. As far as books...my first book was Sams Teach yorself C# in 21 days... it was a awesome book and i totally recommend it to anyone. it was 1300 pages of C# goodness from forms to reflection too xml...but it was nice cause it went at a slow pace....(good for the begining programmer) anyways why do you feel mcsd is a waste of time? what other routes can a 19 year old do to be taken seriously in this lion eat lion field

It should, C++ is very similar to C#, except it has a lot of advanced facilities you can learn once you get past the basics.

Courses typically cost a lot, and teach you enough to have brief retention of all you need to pass the exam. I expect employers to know this. It can't *hurt*, but I don't believe there will be much bang for your buck.

Get published in a magazine. Write an amazing ASP.NET webpage, get it hosted, and put it on your resume. Involve yourself in an open source project as an aid to learning. Write some CP articles.
I agree though - the 1st job is the hardest to get, no matter what.

LOL - no. Although I have used an open source C# lib recently that was missing features I needed, that wasn't what I had in mind.

Best thing that happend to me C# wise was the screensaver contest here on CP. I did one together with James T Johnson and he taught me a great deal.
An open source project is still a *project* and will give you skills in working with others, as well as the chance to learn from them.

Hi all
I have a Thread that adds delegates periodically to a ThreadPool. Now when I debug this in VS.NET every behaves no matter how much delegates gets queued. BUT as soon as I detach from the process, the threads starts going beserk. According to TaskMan the threads are at 35 (max i think). Breaking back into the code I see the thread is still adding delegates but when they fire, i can NOT step thru the code(ok maybe 2/3 statements). It keeps jumping back to the breakpoint.
OK As I was writing this I manage to "fix" it. It seems stable now. It appears to be from using Console.Writeline from a thread. Weird indeed.

its becaused console.writeline blocks threads - i.e. only one thread at a time can execute it.

I have a method that takes byte[] parameter.
But the data, that I want to pass into the method is
contained inside long[] array.
How to convert these types?
I c++ i would simply cast the pointer to (unsigned char*)
e.g
//============= c++
int elCount=10;
long* longTable = new long[elCount];
SomeObject.SomeFunction((unsigned char*)longTable,sizeof(long)*elCount);
In c# it looks like
//============== C#
int elCount=10;
long[] longTable = new long[elCount]
//what to do here to convert long[] to byte[]
SomeObject.SomeFunction(.....)//taking byte[] argument
Is it possible to do it without serialization or any other
"heavy" method
