Tone detection
Hi - I am looking for any examples of detection 1khz tones in dotnet -
or ActiveX for that matter. I wish to detect when the tone starts and
when it stops. Unfortunately, I am finding it very hard to find any
information on this. Can anyone help?

Windows 2003 Enterprise Server - 64-bit Itanium Edition
Hi,
first of all, apologies for posting to mutliple ng's.
We took delivery of a HP Server the other week with dual 2.4GHz Xeon
processor. The rest of the hardware spec isn't important, but we
cannot install the software.
I was asked to try and I looked at the Windows Server 2003 Enterprise
Edition CD (the hologrammed disk) and noticed it says "for 64-bit
Itanium-based systems".
Now this seems straight-forward to me and it isn't the version for our
32-bit CPUs. But does this just mean the disk also works with 64-bit
systems as well as ours.
Or am I completely wrong and our Xeon system is 64-bit (??!!)
Could anybody shed any light for me... it would be nice to have a
straightforward, "yes this is the wrong disk for the system... get a
new one from your supplier".
The disk part number is X09-45883. We are based in the UK.
Cheers and Merry Christmas!

FEATURE REQUEST: Property set via ref parameter
Hi,
It would be nice and a natural way to use a property set by permitting it
to be set via a REF parameter on a method call.
Why this isnt being allowed is beyond me, yes I know they are wrappers for
get_ and set_ methods but if they are there to give the impression of a
FIELD, then they should have all the functionality of a field and not some
half brained implementation.
Thanks. Tag: Enumerating files within a folder Tag: 65113

VBCodeProvider leaks memory on compile?
I've been experimenting with the VBCodeProvider and it appears that it leaks
a small amount of memory every time I call CompileAssemblyFromSource(). It
seems to leak about as much memory as the resulting size of the compiled DLL
on disk.
Is it supposed to do this? Any workarounds? I suppose I could do the
compile in a separate AppDomain which would then get unloaded? (of course
I'd have to use an interface to the code in the AppDomain so I don't lock it
into the main domain). Tag: Enumerating files within a folder Tag: 65097

NEED HELP WITH CERTAIN ASP PAGE NOT DISPLAYING
Hello! I have a question about accessing an .asp page.
The environment I work in, all county stores can access
our intranet fine. However, there is one county that
cannot. This county can login to the intranet fine,
however, when they choose to search by description, like
for instance typing in the item "boots" they press enter
and even get to the asp page that shows the
different "boot" item numbers. When they click on an
item number it just sits there and doesn't do anything
and eventually comes to a white page that says Action
Canceled. They surf through the Internet fine and even
download and upload pages not pertaining to our Intranet
fine. The speed is what it should be when they surf
through other websites. The thing about is, that all
other counties that are hooked up to our systems get in
fine. The one county that has problems, has four
computers in a small LAN and all four are doing the same
thing. I have ran virus checks, removed spyware, cleared
cache, reset the web settings, changed security levels in
IE, updated Windows, reinstalled IE6, and made sure that
no popup blocker or firewall was blocking access to the
certain asp page. The county store does have a router
and I have, from a remote locale got into their router
and even setup the DMZ in the router as the IP address of
the computer and still no luck. PLEASE HELP!!!! Tag: Enumerating files within a folder Tag: 65094

SQL Server Desktop Installation
I recently bought a copy of Visual C#.NET Deluxe Learning addition. I was
under the impression that this comes with SQL Server Desktop Engine. I
installed everything I should have (I think), but when I type the commands
to grant access to SQL at the DOS prompt, it tells me that SQL Server
doesn't exist. The actual error message reads as follows:
[DBMSLCPN]SQL Server does not exist or access denied.
[DBMSLCPN]ConnectionOpen (Connect()).
The problem might be that I also bought a learning addtion of Visual
Basic.NET, and it told me it was installing "different" components than
those already installed. However, I have two DIFFERENT installations of the
.NET framework now; one that allows for C# development and one that allows
for VB development. I can't imagine that ALL components were overwritten.
I suppose I could re-install C# and hope for the best. Does anyone out
there have any experience with this?

Can you redirect framework with config file to an assembly?
Here's a catcher for all ya'll
I have a 3rd party .Net assembly which is compiled against .Net
framework 1.1 and is compatible with v1.0. However, there is not a
way to specify to use 1.0, unless I recompile it against v1.0
I have only .Net framework 1.0 installed.
I have an assembly that references the 3rd party .Net assembly.
I know from MSDN and other postings that a config file can be used
with only .exe and web apps to redirect/rebind which .Net framework to
use. This gets propogated down to the referenced assemblies too.
Is there a way to have my assembly (.dll) to do the exact same
behaviour? Utilize the .net framework v1.0 and propogate that down to
all the referenced assemblies? Including my 3rd party referenced
assembly which compiled against 1.1.
Upgrading to v1.1 Framework will not work becuase of the # of projects
using the v1.0 framework. If I upgrade then they all have to upgrade,
and then the servers have to be upgraded, test, and the list goes on
and on.
I heard of pilicy files in the GAC, but am not quite sure how signing
my assembly and putting that into the GAC will propogate down to any
of the referenced assemblies to use the v1.0 framework.
Any ideas?

Should not be required to release managed resources
A while ago I noticed an issue with .NET that just stung me yet again
today. I had an object that I wanted to be garbage collected but it
registered itself for several events of external objects which entails
giving those objects a delegate that contains a reference to the event
consuming object. The solution I have seen in Microsoft samples is to
unregistered for the events in the Dispose method. Unfortunately, this
creates a situation where manual memory management for these objects
is a requirement. Dispose must be called or they will never be garbage
collected. Garbage collection is supposed to eliminate much of the
need for memory management, but it is not perfect and this is one of
the cases where it fails miserably and quite often.
I came up with a half-solution. I call it the WeakDelegate and it
works well, but in order for its potential to be truly realized it
would need framework level adoption. The concept is that it is a
special kind of delegate that maintains a weak reference instead of a
strong one. Then you simply unregistered for the events in a Dispose
method and call the Dispose method from the finalizer. Worst case is
that the overhead of a finalizer is called.
Maybe in future versions of .NET, delegates defined as:
delegate returnType DelegateName(parameterList);
will really define an abstract class derived from Delegate (or
MulticastDelegate or whatever) as well as two dirivatives of
DelegateName being WeakDelegateName and StrongDelegateName. Generics
may help.
I would love to hear feedback, expecially from a Microsoft rep, with
regards to this idea.
Also, I dug up a prototype from my archives from when I was first
learning C#:

Accessing Data
Hi Friends,
Is there a way to access data from a website that displays
its data from a database.
For example if i visit
http://www.barnesandnoble.com, and if i search for a book
on VB.Net, then i would like to access the results of this
search programatically.
I am trying to access data which is stored in their
database.
Now i can access this data by reading the webpage which
contains the search result.
OR
If "Barnes And Noble" has created a Web Service, which
provides me the access to their database.
OR
If i have direct access to their database.
Are these the only options available to me, to access this
data.
Is there any other way i can get access to this data?
I will be very thankful if you could please provide me any
insight on this.
Any help/guidance will be greatly appreciated.

Crystal Reports - with parms - .Export error
Hey all,
I am trying to try get a crytal report running properly. A "Hello World"
report that does not add criteria to the record selection formula of the
report (either in the development tool, or in the code) works fine.
However, when I try to add any parameter through the record selection
formula and/or the report parameters method, the report crashes.
I have tried each of the methods:
1. Use the Record Selection Formula property:
crReportDocument.DataDefinition.RecordSelectionFormula = "{qryTest.ID} =
54"
2. Use the Crystal Parameters collection(s)
crParameterFieldDefinitions =
crReportDocument.DataDefinition.ParameterFields
crParameterFieldDefinition = crParameterFieldDefinitions.Item
("[@TestID]")
crParameterValues = crParameterFieldDefinition.CurrentValues
crParameterDiscreteValue = New
CrystalDecisions.Shared.ParameterDiscreteValue()
crParameterDiscreteValue.Value = 54
crParameterValues.Add(crParameterDiscreteValue)
crParameterFieldDefinition.ApplyCurrentValues(crParameterValues)
Both of the methods above work fine on my development machine but the
testing server gives these errors.
I also set the record selection formula in the report to automatically
set the TestID parameter = 54 and then tested that report on the testing
server and everything worked.
So the issue seems to be with populating the crystal report's parameters
at runtime. The error that comes back with a logon failure at the .Export
line.
I have tried two methods to logon to the reports:
####################
Basic:
With tliTableLogonInfo.ConnectionInfo
.ServerName = m_strDSNName
.DatabaseName = m_strDatabase
.UserID = m_strUserId
.Password = m_strPassword
End With
'setup each connection in the report
For Each tTable In crReportDocument.Database.Tables
tTable.ApplyLogOnInfo(tliTableLogonInfo)
Next tTable
####################
and Complex (loops through sub-reports):
Dim mySection As Section
Dim mySections As Sections
Dim myReportObject As ReportObject
Dim myReportObjects As ReportObjects
Dim mySubReportObject As SubreportObject
Dim mySubRepDoc As New ReportDocument()
'Declare all of the sections of the main report
mySections = crReportDocument.ReportDefinition.Sections
'Loop through the sections in the main report to find the subreport
objects
'then set the logon information to the subreport
Dim myLogin As CrystalDecisions.Shared.TableLogOnInfo
For Each mySection In mySections
myReportObjects = mySection.ReportObjects
For Each myReportObject In myReportObjects
If myReportObject.Kind = ReportObjectKind.SubreportObject Then
'Subreport Found - convert the report object to a sub report type
mySubReportObject = CType(myReportObject,
SubreportObject)
'Set the specific instance of this subreport
mySubRepDoc = mySubReportObject.OpenSubreport
(mySubReportObject.SubreportName)
'Set the login information for the current subreport(found)
For Each crTable In mySubRepDoc.Database.Tables
myLogin = crTable.LogOnInfo
myLogin.ConnectionInfo.ServerName = m_strDSNName
myLogin.ConnectionInfo.DatabaseName =
m_strDatabase
myLogin.ConnectionInfo.UserID = m_strUserId
myLogin.ConnectionInfo.Password = m_strPassword
crTable.ApplyLogOnInfo(myLogin)
Next
End If
Next
Next
####################
Does anyone know of other methods to filter a report at runtime? Or is
there a Crystal DLL that I need to move from my dev machine to the server
to allow for the record selection properties to be set at runtime?
OR ANY OTHER INFO WOULD BE GREAT!!!

just in time debugger

bringing up the just in time debugger? i don't want
this. during normal running, we want the application to
just die on a crash. what happens is the just in time
comes up on the server and it just sits there with the
app in a hung state. we have another process running
that if any .exe "disappears", it restarts it. when JIT
comes up, it doesn't disappear and the server just sits
there dead. of course we need to find what is causing
this, but when running in production state, we need jit
to be disabled.

Uninstalling a NT Service programmatically
Hi NG,
I'm writing a management tool for our software, that among other should be
able to install and uninstall some of our NT services.
The problem is that when I uninstall the services (using
ManagedInstallerClass.InstallHelper with the "/u" parameter) the services
are uninstalled, but they are still running until I close my management
application. This is a problem since I want to remove the service assemblies
as a part of the uninstallation.
I read the Knowledge Base-article 287516
(http://support.microsoft.com/default.aspx?scid=kb;en-us;287516), which
seems to be addressing my problem. It claims that all handles to the
services needs to be closed before the service can be uninstalled. Thats
fair enough, but eventhough all my ServiceControllers are Close()'d and
Dispose()'d the problem persists.
Is there a way to release all handles to a service allowing it to be
uninstalled at once?
Or is there another way to do this?
Thanks for your time,

"SystemAccount" rights and "Allow service to interact with desktop" but I
know it leaves the system vulnerable to maliciousness.
Is there a way to programmatically enumerate through the current desktop
windows when running as a service?
Also, How I can know the name of the user when he logged?
Thanks in advance Tag: Enumerating files within a folder Tag: 65035

.Net Framework SDK Licence Agreement and OpenSource
I am looking to start an Open Source project using C# but
the requirements of the project require that the project
must be written in a language that has freely available
compilers.
I am correct in think that the .Net Framework SDK is a
free download from Microsoft and could be used for such
an Open Source project with these requirements?
I have tried finding an End User License agreement for
the SDK without success. Can someone provide me with a
URL to such an agreement so that I can provide this to
the administrators of the Open Source project to satisfy
their concerns.
Thanks in Advance

activex textbox vs windows forms textbox
I'm porting an MS Access application to a .NET windows forms application.
For several forms I need to use textboxes which support input masks and
whose border color I can change, neither of which seem native to .NET.
Is the addition of activex controls my only solution. So far, I've only
found Microsoft's masked edit control (V6) which supports the input mask,
but doesn't give me any control over the border color.
Does anyone know if there are any better activex textboxes out there which
fit the bill, or if there is a native dotnet solution that I'm missing and I
could implement?

clearing back history in IE
Hi all! Can anyone tell me how do I clear the history in Internet Explorer's Back button, so that when the app gets redirected to a certain form the user won't get the possibility of getting back to the previous one using the back button... In particular, I have a login form, and after the user logs in, I don't want the user to get back there unless he/she logs out
Thanks

{ in a string.Format
How do you escape a { in a format string for string.Format?
I want to have a format string that builds code, something like "static void
{0}() { {1} }". I know there are other solutions like building the {1} with
the brackets.

GetObject in .NET c#
Dear All,
I have to move my VB code to C#. But I have no idea on the GetObject method
in Vb.
-----------------------------------------
Set dom = GetObject("WinNT://" & domain)
-----------------------------------------
This is easy for VB to get the object by COM monikor interface.
However, what I use the following code to active a object via monikor in c#,
what I got is a OBJECT Type.
----------------------------------------------
Marshal.BindToMoniker("WinNT://" + strDomain); //c# code
----------------------------------------------
Is there any way for me to KNOW the returned object type and case it to the
right type in .net???
Thanks very much!

Configurable print formats.
Hi;
We have a requirement in our application wherein all the TEXT in the
application especially the print formats for the documents and reports
are configurable files that would be part of the software packaging.
In other words, these formats can be changed, but the software need
not be re-loaded. We will just need to download the latest formats on
the handheld.
I would appreciate any pointers on how to go about doing this.
Thanks and Kind Regards;

HttpWebResponse can't handle duplicate header
Hi,
HttpWebResponse will just display the last value of
those same name http header.
Ex.
Aheader: a value
Bheader: b value
Cheader: c value 1
Cheader: c value 2
Cheader: c value 3
Dheader: d value
Retrieving the Cheader value by the headers property of
httpwebresponse will only return the "c value 3".
Is there any workaround?
Thanks

How to detect files copying
Hi,
I mean:
I would like that my software has capacity to detect files-copying process
into my harddisk (it is the same Norton Antivirus detects what files are
copying and do stop that copying process).
So, my software can prevent process of copying(installing) of somefiles. My
question is how can I know that process (where is it copy from?, What is its
name? ...)
I attempted to use FileSystemWatcher() but I couldnot know where files come
from. What I need is prevent copying from somefiles (they come from
Floppies, CDROM) so I must know where those files come from.
Please help me as soon as possible.
It is urgent for me.
Thank you. Tag: Enumerating files within a folder Tag: 65010

line control in VStudio.NET
Looking for the good ol' Line Control in Visual Studio.NET that earlier used
to be part of the standard toolbox in VB6.
Any suggestions.
If there is no such control in VS.NET can anyone recommend a good way to
draw lines on WinForms.

System.Array.Rank (MS BUG?)
The docs say System.Array.Rank will provide the number of dimensions in the
array. But does not seem to work.
I get 2 back for both 2 and 3 levels of dimensions in the array.
I am forced to use Com interop, could that be breaking this?
I am also using VB.NET.
Strange output.
See my code and locals window copy below:
Looks like a MS bug to me

Update on timer question...
The behaviour I'm getting is that my timer is going off like an infiniant
loop, sending hundreds of requests to my e-mail function. Sorry not to
include that in my original post.

Is there an upward limit to the System.Timers.Timer.Interval value?
I am using a timer in my Windows service previously discussed in my previous
post to send warning e-mails to users who's account activity idle for a
given number of days. Currently I have it set for 30 days, which I multiply
by a base value for one day in milliseconds. The value that is currently
being used is: 2592000000, which when divided by 24 * (60^2) * 1000 comes
out to 30 days as it should. Can the timer not be used in this way? If it
can't how does one accomplish this type of timing?

Hi.
Not sure if 1st message posted .. how do I enumerate all
the files within a named folder? Have used Delphi's
FileNext function in the past to do this.
Have you tried the Directory.GetFiles() method?
The DIrectory class is found in the System.IO namespace.
