You're looking in the wrong place to see what memory is being used by your application. In Task Manager, you're seeing what memory has been RESERVED for the entire .NET Framework and it's virtual machine that runs your application, otherwise known as the CLR (Common Language Runtime). Some of this memory is not permanently allocated to your "application", but is reserved for future use. This means that if Windows wants some of that memory back, the .NET CLR Memory Manager will release whatever Windows wants back to the system.
The .NET CLR Memory Manager keeps the memory reserved for performance reasons. Since you've used a large chunk of memory before, you might need it again, so the Manager hangs on to it, even though your application hasn't allocated it again. Since it's a little time consuming to allocate memory from the system (adding it to the .NET managed memory heap), then allocate your managed object on that heap, the .NET Memory Manager will try to skip the first step, if at all possible, by reserving memory for future use.
If Windows needs the memory back for something else, the .NET CLR Memory Manager is more than happy to free up whatever Windows needs. If you want to see the real memory counters, open up Performance Monitor and use the memory counters under the .NET CLR Memory performance object.

You're not very specific about what you mean by "copy my application". I'm assuming you just want to copy your .EXE and .DLL files. There's a very short example here[^] on how to copy a file.

with a datagrid in a winform
single click on the datagrid:
my program must do one think(change the color of a single cell) - OK
double click on in the datagrid:
the program must show a panel the content if the datable "under" the datagrid - OK
the datagrid class has 2 method datagrid1.doubleclick end datagrid1.click
well when i click two times (doubleclick method) the program executes one time the dobleclikc and two times the single click
*************************************************************************************
Private Sub DataGrid1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGrid1.MouseHover
Dim xxx As System.Windows.Forms.MouseEventArgs
Dim sss As Integer
sss = xxx.Clicks
If sss > 0 Then
If xxx.Clicks = 1 Then
'here code the inside datagri1.click
End If
If xxx.Clicks >2 Then
'here code the inside datagri1.doubleclick
End If
End If
End Sub
i take this exception
"System.NullReferenceException" in forfat1.exe
my question is:
how can i intercept the the single and the double click if mouse is over datagrid (mousehover method) bypassing commands datagrid.click end doubleclick end even mousedown????
thanks a lot and forgive my bad english

You need to explicitly close it; I assume your using automation to do the work?
So
objExcel.Close
objExcel = Nothing

Hi,
I developed a Client side proxy using sockets. And, I am able to get some sites without any problem.
But, I am facing problem in capturing data from few sites. Particularly Secured sites and whenever a website refers to another server (Location). I am getting HTTP/Other messages like:

You posted this message in 2005 and I hope you solved your problem by now, if not I would have to see your code to be able to help you. There are lots of things involved in writing a good and stable proxy server. Listening on multiple threads and being able to catch streams are some of the main issues.

Howdy!!
I've been working on a VB.net program to:
1. Rip data from a **Huge** Text file.
2. Encode that data to an XML URL
3. Pull the data from the XML from the website
4. Enter that data into an Access Database
Access 2002 to create reports from data.
Is there anyone out there that would be willing to help me optomize my program and database for performance and help me with error handling???
Right now it takes over a half hour to itterate through the .txt file (roughly 10,000 lines) and do its thing. My 'error handling' is me clicking OK on tons of errors... lol
Email me @ geoff at azpmc dot com if you'd like to help out a r00kie!

First question - why are you using XML ? Because it's coming through a web service ? If the files are huge, then wrapping them in XML tags won't do anything good. Secondly, how are you parsing the XML document ? You should use an XMLReader to provide a forward only reader, instead of XMLDocument, which will give you the DOM, at huge cost on a document of this size.

The original text file is just a bunch of addresses. That part never sees XML.
Part one of the program takes the street number, st. name, city, state, zip and puts into a URL, calls the url as the source of the XML document. It then uses XMLtextReader to do this:
(the XML file is pretty small.... really small...why does this program chug so bad????)
Private Sub readXML(ByVal newURL As String, ByVal stnumber As Integer)
Dim anewURL As String = newURL
Dim reader As XmlTextReader = New XmlTextReader(anewURL)
Dim output As String
Dim name As String
Dim contents As String
Dim fName As String
Dim lName As String
Dim stName As String
Dim phoneNumber As String
Dim phone2 As String
Dim phone3 As String
Dim phone4 As String
Dim city As String
Dim state As String
Dim zip As Integer
Dim yesNo As String
Dim countYesNo As String
Dim contentInteger As Integer
reader.WhitespaceHandling = WhitespaceHandling.None
While reader.Read()
reader.MoveToContent()
If reader.NodeType = Xml.XmlNodeType.Element Then
name = reader.Name
contents = reader.ReadString()
reader.MoveToElement()
reader.MoveToFirstAttribute()
If name = "NAME" Then
reader.MoveToFirstAttribute()
contents = reader.ReadString()
fName = contents
End If
If name = "ADDRESS" Then
reader.MoveToFirstAttribute()
contents = reader.ReadString()
stnumber = contents
End If
Select Case name
Case "COUNT"
countYesNo = contents
Case "STATUS"
yesNo = contents
Case "LAST"
lName = contents
Case "STREET"
stName = contents
Case "CITY"
city = contents
Case "STATE"
state = contents
Case "ZIP"
zip = contents
Case "PHONE"
phoneNumber = contents
End Select
End If
End While
If yesNo = "OK" Then
addPhoneNumber(fName, lName, stnumber, stName, phoneNumber, city, state, zip)
End If
reader.Close()
End Sub

Does anyone out there think that there's a way to get this function to run faster?

What format is the text file in? If it’s a comma separated file (or you can change the file format to a CSV) then adding this data to the access db is easy.
I have always wanted to try this, but never had a need for it.
Create a record set based on the CSV file, close the connection open a new connection to the access db. Attach the new connection to the record set and update it to the access db. Done, no extra data parsing needed, again never tried anything like this. If it works let me know…
Hope that helps.

The text file contains a giant list of addresses and a bunch of other usless junk.
They look like this:
10/21/2005 9:12:34AM2331 WEST RIVER RDSearch Report
West Dennis, MA 02661
10/21/2005 9:12:34AM2331 WEST RIVER RDSearch Report
West Dennis, MA 02661
10/21/2005 9:12:34AM2331 WEST RIVER RDSearch Report
West Dennis, MA 02661
10/21/2005 9:12:34AM2331 WEST RIVER RDSearch Report
West Dennis, MA 02661
etc...
I have to parse the data from that to a URL something like this:
www.lookuptheaddress.com&stnum=2331&stName=West+river+rd&city=west+dennis...
That URL produces an XML page that I need to pull Name and Phone Number from and then slap into a database for later use...
i think what is bogging it down is the XML data parsing... Im going to re-work it using the XMLDocument methods and see if that helps any...
Thanks for the help and I welcome ANY input on this porject!!
_thanks again!

Why can’t you add the information to the database as your creating the XML document (that’s provided the XML Document is needed for something else)? Just fire off a simple insert into the database, you have all of the data already right there.

Test it; see how long each piece of the pie takes. Start with cleaning up the flat file, then creating the XML document and finally adding the data.

The Name and Number come from the XML... it's a lookup service that im using on the internet.

What would be a good method for testing and timing operations besides guestimating?
Thanks!
