hi,
im doing a project now.In that i used plenty of variables like
datasets,arraylist and other things.It takes lot of memory while using
these objects.eventhough i disposed that objects(using dataset.dispose(),clear(),reset(),similiarly for arraylist and others ) it still not releasing the memory.we tried GC collect also.but unable to solve the
problem
thanx in advance

Are you getting any error ? Make sure all instances which has a Dispose() method is called once you finish using it. Put the class instances which are disposable in a using statement. This ensures the disposal of objects.

I have disposed memory like this for dataset and arraylist etc.....
but initally it will take 13,000 K amount of memory but after finish the program it is taking 80,000 k amount of memory even if dispose like this......
for dataset......
F_Info_set.Dispose();
T_Info_set.Dispose();
F_Cnt_DB.Dispose();
T_Cnt_DB.Dispose(); T_update_set.Clear();
F_update_set.Clear();
Distinct_date_set.Dispose();
for arraylist.......
Date_List.Clear();
ls_Item.Remove();
Chk_item.Remove();
rec_Item.Remove();
sorted_Mdb.Clear();
temp_Sort.Clear();
D_info.Clear();
Change_date.Clear();
for DBconnection....
db_con.Dispose(); for DBcommand....
db_com.Dispose();
dd_com.Dispose();
F_insert_cmd = null;
T_insert_cmd = null;
del_integ_mdb = null;
for DBadapter.....
db_adap.Dispose();
dd_adap = null;
F_info = null;
drrow = null;

Hello,
Apart from Disposing, you have to make sure, that there are no references to your objects "alive".
I would recommend the usage of a memory profiler!
All the best,
Martin

Odds are very high that you're fine. The objects you refer to are not very big, and the task manager is a poor way to work out how much memory your app is using.

starting from 16000 it reaches nearly 80000k.and never it came back to the normal range

It sounds like you are using TaskManager to look at your memory usage. You should use PerfMon instead since TaskManager is obly reporting the total amount of memory allocated to the runtime process not how much memory you are actually using.
You shouldn't make direct calls to GC.Collect as that will end up hurting your performance in the long run.
As long as you are properly disposing of your objects (make sure you are using a try..finally block or the using statement) you should be fine. If you really want to see what is going on, you will need to use a memory profiler like the CLR Profiler.

any body help me to calculate the factorial value of any inputed number.
Note: Be sure bcz no. of code available but all are calculated only <100.

And what is the factorial of 100? Does the answer give you an idea why code to compute anything higher isn't generally available?

Do your own homework. And, read the assignment.

Hey Guys
Me and the guys on my DevTeam are busy doing planning for our software (a time and atendance system)
Our aim is to have a Server application (this will contain a calculation routine and a communication routine), and a client application (setting up shifts, employees, etc and give reports)
we are stil in the process of deciding how we will have these programs "talk" to eachother.
something that will influence the final decision greatly is if we can get data from devices on the client machines from our server app. So i need to have access to a remote computers com ports
im sure its not imposible, but have any of you guys atempted something simmilar? can u point in in a direction? or even just give a thuaght on the idea
Thanx

Will your client application running on client machine? In that case use that client application to hande the com ports and server application to communicate with the client application. If you do not install your client application on client machine (I wonder) then design an application (service type) for the purpose. Are you planning to use a smart card reader or similar thing? Windows has default support through GINA.

yes the client will be running on a client pc, but not always! some of our clients (actual ppl  ) wont use our software with multiple users so they will have the client and server on the same pc and a periphiral device on its com port.
the devices we get data from ranges from fingerprint scanners to palm scanners to proximity scanners (those use a card as "key"). they are all used as an offline system IE when a person puts his finger on the scanner the record of it stays on the scanner until "polled" by our server app, only then all the records are transfered from the scanner to the server which will then write it to a database and let the client applications know there is some new data
now in some cases our clients may have more than one scanner, but only one connected to a pc. so in that case a scanner will be on clientPcOne and another on clientPcTwo. serverPc must be able to get to the data on the scanners from its location using clientPcOne and clientPcTwo as a "gateway" to the scanners if that makes sence
thanx

I have worked with Mifire and proximity cards. I used a windows service (back then I wrote using c++) to commulicate with the card readers. Then the service would use webservice and send the data to a central server pc. If your situation is not much different you can use this method. But in this case you need a service always running background.

well the server app will be a service running in the background, or thats the plan atleast

Sorry, but I do not understand the point of controlling a port from remote location. This means you need a driver that listens to a specific port for remote control commands. What I was sugesting is to control a remote application- not port- and let that application control port. Should not it work for your purpose?
|
|
|
|
|
yes that should do the trick!
this was the point of the thread, to get posible ideas from others who have atempted it and then decide which way will suite our needs best
but your idea sounds like it will work perfectly...
another colegue of mine asked me to look into the topic and posibility of controlling a com port remotely...
thanx for your idea

Hi all,
I'm looking for a C# library to create a grid (multi column) with hirarchy view (Treelist)
waiting for your suggestion
Thanks

yes I try google but I can't find the feature I need
I want to have a TreeList (hierarchy + multicolumn)
and I want to have two fields of information in one column
-------------------------------
| column1 | column2 |
|---------|---------|-
|c11 |c12 | c21|c22 |
---------|----|----|----|----|-
+Node1 | 0 | 10| 15| x |
-Node2 | x | x | x | x |
+Node21| | | | |
Thanks for any help

Hi,
I have ClassA, ClassB. ClassB inherits ClassA.
How do I de-couple these classes, so that, If i make changes to ClassA, ClassB wont be affected?.
and I wont have to modify ClassB(rebuild)
how to generalize?
-Pete

By causing them not to be inherited from one another ? Perhaps define a common interface that defines the part you want to exist between the two classes.
