Depending on how safe you want your license to be making it yourself can be very complicated.
There are several commercial components which do what you need. One of them is this[^] on.

I have developed an windows service in C# the working of service is to fetch data from database generate some messages and store those messages in database.
The problem i am faceing is the memory consumption of my service is very it goes upto 2GB and due to this the system hangs.
I have disposed all the objects and also i am invoking garbage collector after
specific amount of time but the memory still increse.
The service is running on Windows-2003 server.

You're missing something somewhere. You're going to have to profile your code with something like CLRProfiler to get its memory consumption.

You just about NEVER have to do this. Did you know that your entire application, ALL of it's threads, come to a complete halt when the garbage collector runs? Still think this is a good idea?

I have already profiled my code using .Net Memory profiler, Ants profiler and also CLR profiler
and changed my code according to the results of above profilers.
Is there something another way by which i can come to know which objects are in memory and not getting disposed

The CLR Profiler will tell you, if you know how to read it.

im using a js function to dynamically fill a dropdown.
im using document.getElementById('dd') for getting the id of the select box.
first it was working properly and now not.
document.getElementById('dd') retuning a null and previosly it was returning a object. so im not getting the binding.
what could be the problem

Have you checked the source of the page? What id does the dropdown get?
If you moved the dropdown inside a container, the id can change.

b { font-weight: normal; }

thanx a lot Guffa

the id for the select tag is 'dd' only ...

i cant get this above point ???
i dunno why im gettin that null ...

Well, if the id in the tag is correct, then there has to be something else in your code that causes the problem.
Do you have any other element with the same id?
imsathy wrote: i cant get this above point ???
If you put the dropdown in a user control, for an example, with the id "froglegs", the dropdown would get the id "froglegs_dd". If you put the dropdown in a repeater, each dropdown created would get a unique id, like "Ctrl_42".

i tried keeping some unique name. but null is wat it returns if check tat wit a alert.
but my previous similar coding in the source gear is workin perfectly

Test by giving the element a different id, just to see if that makes the javascript work.
Also check for other errors in the page source. For an example, if the element is placed outside the form, it might be ignored by the browser.

thanx a lot Guffa.....
the error was bcoz i was callin the function inside the script and not on the onload event of the page  .....

I assume that you mean the data type Memo, the text type that can hold more than 255 characters.
Are you really sure that the value is empty? As I can se, the string starts with a line break, that means that you have to heighten the rows in Access to see the other lines in the field.

I have written an application that uses pop-up forms to view data etc.
Everything works perfectly well until you try and close the pop-up. I am using the this.close() function and instead of closing the pop-up window leaving you viewing the main window it closes the whole application.
I then reverted to using the this.hide() mehtod and while it works if i try to go back to the hidden window (ie try to re-open the form with different data) it more often than not crashes
if anyone has any ideas then that would be appreciated!
Regards
Paul.
