Release All The Memory?
Oct 1, 2010in main form, when a button is clicked, it opens a new form which has a webbrowser. users can use it to browser some sites. if the user closed this form, it goes back to the main form. and they can click button to open the browser form again.
I noticed that one thing. if the browser form is opened, it uses much memory (which is normal because of the site it browses). however, after the browser form is closed, the memory is not released.
In the browser form, when it is closing, the webbrowser is disposed and dereferenced. and no other part uses much memory in the form. GC is called too. what else should I do to release all memory the browser form uses?
now, it is like once the browser form is opened once, the memory usage never goes down even the form is closed.

Rotational Functional Tester Tool - Memory Release
Sep 29, 2011I am using Rational Functional Tester(RFT) tool with Visual Studio 2010. The scripts are written in Vb.net. The application gets slower frequently and sometimes the browser gets hang..I assume the problem is in memory leakage. We are cleaning the memory of objects by calling dispose in finally but still there is no improvement. How can we increase the performance at the best in terms of memory.

Apr 13, 2010An application that has 3 Webbrowsers instantiated at design time navigates to webbrowser2 15 times every minute with a different webpage.

Jul 23, 2009I am using excel to store and retrieve information. I open the excel work book then close it once the action is completed. I thought it was clearing fine till i opened my Task Manager and found a ton of instances in the Task Manager. I can clear them manually but my users are not going to do that and it is cheesy to have them have to do that. I have researched this and some folks were talking about a "Marshal" method. I researched that and don't understand what it does.[code]...

C# - Managing A Debug And Release Connection String
Mar 4, 2010What is a good approach to managing a debug and release connection string in a .NET / SQLServer application?
I have two SQL Servers, a production and a build/debug and I need a method of switching between the two when my ASP.NET application is deployed.
Currently I simply store them in the web.config and comment one or the other out, however that is error prone when deploying.

I could be way off here, but it almost seems like ID.IDlist points to the address of mylist and so when mylist is cleared so is ID.Idlist. It seems as though the reason the second block of code works is because I am creating a new list in memory for each ID object and ID.IDlist just points to it... is that right?

.Net: Empty String Is Not Clear Space Character?
Apr 7, 2009I've always use String.IsNullOrEmpty to check for a empty string. It recently come to my attention that a " " count as not a empty string. For example,
Dim test As String = " "
If String.IsNullOrEmpty(test) Then
MessageBox.Show("Empty String")
[Code]....
It will show "Not Empty String". So how do we check for " " or " " in a string?
edit: I wasn't aware that " " count as character.
