Casting IEnumerable<T> to IEnumerable<V>
Suppose a collection class defined as:
public class Friends: ReadOnlyCollection<Friend> {}
where Friend implements IPerson:
public class Friend:IPerson {}
My question: is there a neat+lean way to implement IEnumerable<Person>
in the collection class?:
public class Friends: ReadOnlyCollection<Friend>, IEnumerable<Person>
{
public new IEnumerator<Person> GetEnumerator()
{
// ******* CAST DOES NOT WORK **********
return (IEnumerator < IVSelItem >) base.GetEnumerator();
}
}
Any suggestions?
Thanks in advance. Tag: squishyTree component ASP.NET 1.1 Tag: 118567
Creating extra classes
I recently upgraded from VS 2003 to VS 2005. In VS 2003 all I had to do to
make an extra class was put the following in a *.vb file:
Imports System.Web.UI
Imports System.Web.UI.WebControls
Public Class MiscExtras
Public Shared Sub AddRollover(ByVal img As Web.UI.WebControls.Image,
ByVal rollover As String)
'Adds the rollover feature to an Image or ImageButton (or other
class that inherits from an Image)
img.Attributes.Add("onmouseover", "this.src='" & rollover & "';")
img.Attributes.Add("onmouseout", "this.src='" & img.ImageUrl & "';")
End Sub
End Class
And then to access it from a file in the same I would use the following:
MiscExtras.AddRollover(imgHomeButton,
"images/MenuBarButtons/HomeRollover.gif")
However, when I try to do this in Visual Studio .NET 2005 I get the error
'Name MiscExtras is not declared.'. I also tried putting the file in the
App_Data directory that is automatically created, but it did not make any
difference. What am I doing wrong? Thanks.

ImageAttributes isn't working
Hello,
For some reason this ImageAttributes isn't doing what I tell it. I'm
not sure what I am missing. I am trying to get background of the image
to display as transparent. But it draws the image unchanged. Here's
my code.
Dim ImgColorMap(0) As System.Drawing.Imaging.ColorMap
Dim BackColor As Color
'Draw the Background
graph.DrawImage(BackGroundImage, 0, 0)
'Draw the board
BackColor = BoardImages(0).GetPixel(0, 0)
ImgColorMap(0) = New System.Drawing.Imaging.ColorMap
ImgColorMap(0).OldColor = New Color
ImgColorMap(0).OldColor.FromArgb(BackColor.A, BackColor.R,
BackColor.G, BackColor.B)
ImgColorMap(0).NewColor = New Color
ImgColorMap(0).NewColor.FromArgb(0, 0, BackColor.G, 0)
BoardImageAttributes = New
System.Drawing.Imaging.ImageAttributes
BoardImageAttributes.SetRemapTable(ImgColorMap)
graph.DrawImage(BoardImages(0), New Rectangle(50, 50, 50, 50),
28, 28, 50, 50, GraphicsUnit.Pixel, BoardImageAttributes) Tag: squishyTree component ASP.NET 1.1 Tag: 118549
Convert to Long from Double that is over 18 digit long from Oracle
This is a serious bug in .NET 1.1
Using SQL select one field from Oracle table,
This column Oracle data type is: Number(18),
the field value is: 235312035283022003
which is the correct value.
However, using DataReader,
(We want the end result is long type, the only way is GetDouble(reader,0))
Here is the horrible result .NET Returns:
long viewId = 0;//We want the end result is long type,
double dViewId = reader.GetDouble(0);
viewId = (long)dViewId; // we get 235312035283022016
string sViewId = dViewId.ToString("R");//we get "2.35312035283022E+17"
sViewId = dViewId.ToString("F0");//we get 235312035283022000
viewId = long.Parse(sViewId);//235312035283022000
No matter what, we cannot get the correct value:
235312035283022003
This bug happenend when double value reaching 18 digit long.
It is fine when under 17 digit.
Any known work around?
How Microsoft proved .NET is able to be mission-critical?
We are a leading Telecom company, currently reaching the buggy-threshold in
our billing system due to this bug. Any help are appreciated.
Thanks.

ASP.NET: VSNET2003 to VSNET2005
I just upgraded from Visual Studio .NET 2003 to Visual Studio .NET 2005.
There are several questions I have about the code differences between them
(I use VB.NET for as my language of choice):
1. 2003 used "Public Class classname" and 2005 uses "Partial Class
classname". What, if any, difference is there between these?
2. The following things are included in the #Region " Web Form Designer
Generated Code " part of 2003's code, and are not included automatically in
2005:
<System.Diagnostics.DebuggerStepThrough()> Private Sub
InitializeComponent()
End Sub
Control declarations, such as:
Protected WithEvents lblWebsite As System.Web.UI.WebControls.Label
Private designerPlaceholderDeclaration As System.Object
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Init
InitializeComponent()
End Sub
Do I need to include any of these manually or anything else that serves
their purpose?
3. In 2003 the Page Events use clauses such as Handles MyBase.Load while
2005 uses Handles Me.Load. I am assuming that these will work the same?
I am sure that I will run into the other differences between the two, but
these are some of the important ones for me right now. Thanks.

How to Stop a Listening socket?
I'm trying to make a simple little asynchronous socket server. It accepts
connections, reads and writes, but I can't make it gracefully stop listening.
listener.listen(1)
listener.beginaccept(...)
If before anyone has attempted to connect, I try to stop the listener
socket, I get nasty errors, which I can trap, but it is not obvious that it
has actually stopped or that the asynchronous callback system has been
aborted. This should be trivial. What am I missing? Tag: squishyTree component ASP.NET 1.1 Tag: 118518
Now I need to do this without breaking ASP.Net
I've been struggling for two weeks now to duplicate a VB6 ActiveX control in
VB.Net, and also improve it's functionality. The control is used to collect
the user's fingerprint and compare it to a stored copy on the server, and if
the match is successful fill some hidden fields with values and call a form
submit. We wanted to use web services rather than direct SQL connections as
we do now, and to also have the web service URL set dynamically.
We built the project as a Windows Control (DLL) class with COM Class and COM
Visible set to True. We were able to get the control to load in IE, but due
to the need to interface with the local USB fingerprint device we had to
list the web site as Trusted and elevate the Trusted Zone to perform no
security checks (Problem #1).
The class required a couple of DLL files to function properly, and as
expected we were able to put them in the same folder as the class DLL file
and they were downloaded automatically. The problem was the App.Config
file, it never would download. (Problem #2) We recently figured out that
apparently a DLL can't make use of App.Config, but the calling app can.
This explained seeing the client attempt to download iexplore.exe.config in
the web logs. To make matters worse, it wasn't attempting to download the
file from the location of the class DLL, but rather from the root of the web
site and from /bin folder. (Problem #3)
So we renamed the App.Config file and placed it in the root. It still would
not download, this time with 403 Errors which we determined were the ASP.Net
interpreter trying to process the file rather than allow direct access.
(Problem #4) We decided to remove the parsing of .config files from the
configuration of the root web app, which finally allowed everything to
execute properly. But now, if we had any web.config files in the root app,
they would be open to being freely downloaded, and might not even work at
all (Problem #5)
I just know there has to be a better way to do this. I cannot believe that
it's this difficult with .Net to duplicate and improve on the functionality
we had using VB6. Perhaps someone with experience in things such as this
will step forward and point us in another direction.
Thanks,

RSACryptoServiceProvider.VerifyData Hangs
I have found that RSACryptoServiceProvider.VerifyData sometimes hangs for
several (typically 6 or more) seconds. This is very irritating since a
component that I am using makes this call every time a form in my
application opens. The entire application freezes. Obviously it makes my
application very sluggish.
Mind you, on some machines the above always seems to be very quick. And on
others it can be quick for several minutes, and then start hanging for a
while.
I'm using .Net Framework 2.0. Here is some sample code from my very basic
"hello world" application, followed by the trace output (generated using
Enterprise Library)...

xml formatted string here]
private string xmlData = [I have an approximately 470 character xml
formatted string here]
private string Signature = [I have an approximately 200 character
base 64 encoded string here]

encryptionService.FromXmlString(publicKey);
Trace("After

Up/down value conversions
Greetings,
We are using an up/down control to facilitate numeric data entry,
however, we are noticing issues converting from the up/down value
(apparently a Decimal) to the units we are working with (Double) and
vice versa. There appear to be precision issues, and then we take those
numbers and scale them according to our application requirements.
Needless to say, the results are anything but what we might expect. We
could be doing some wacky scaling, but notwithstanding that, is there
anything we can do to help clean up the conversion between Decimal and
Double? Or is the answer to provide a control that better-supports a
Double-compatible input? Any suggestions are welcome. Thanks in
advance.

MS Unit test and CruiseControl.Net integration
Hi All,
We are currently running continous integration using a server running
cruise control.net. This server does not have VS2005 installed on it,
only the .Net framework.
Previously, we have been using Nunit to write our tests but I thought I
would give the integrated MS unit test a go and submitted these test to
source control.... Which has broken the build because the
Microsoft.VisualStudio.QualityTools.UnitTestFramework dll is not
present on the server....
So my question is, can you run MS unit tests as part of an automated
build process without having a full install of VS2005 on the
integration server?

Creation of HTTP streaming server using .NET HttpListener
Hi,
I'm posting this in the general .NET forum because I'm not sure into which
subcategory this belongs. I've searched through the newsgroups and found many
posts related to audio/video streaming mainly using the Windows Media
Services.
I'm trying to create an HTTP server in C# (using HttpListener,
HttpListenerRequest and HttpListenerResponse) where I can stream videos to
potentially any media player that can stream via HTTP (WMP, RealMedia, VLC).
The reason why I want to do it this way is because I already have a stream in
the ASF format, so I just need to split it in packets and send it out. So far
I haven't been able to get a stream to work correctly primarily because I
wasn't able to setup the response parameters to what they'd need to be.
It seems that I either have to set the 'Transfer-encoding' to 'chunked' or
specify the content length.
Has anyone done anything similar to this with these classes or does anyone
know if that's possible at all?

Update Profile of Created User
I've created my own version of the CreateUserWizard control that gathers up
all the information I need when a user requests an account. Once all the
data is gathered and validated, the FinishButtonClick property calls a method
that does the following:
1. Creates the user account:
Membership.CreateUser(myName, myPwd, myName, myQue, myAns, true, out
createStatus);
(I'm using the email address (myName) as the username, which is why it shows
up twice)
2. I then want to update the newly created user's profile with the
information that was entered:
Profile.UserInfo.UserEmail = UserName.Text;
Profile.UserInfo.FirstName = FirstName.Text;
Profile.UserInfo.MiddleInitial = MI.Text;
..etc.
I do not want these profiles created for anonymous users, so my web.config
file looks like this:
<anonymousIdentification enabled="false" />
<properties>
<group name="UserInfo">
<add name="FirstName" type="System.String" allowAnonymous="false" />
<add name="MiddleInitial" type="System.String"
allowAnonymous="false" />
<add name="LastName" type="System.String" allowAnonymous="false" />
..etc.
</group>
</properties>
I have tried several methods to ensure that the newly created user is logged
in, by using the Membership.ValidateUser(), the
FormsAuthentications.AuthorizeUser(), and none of them have worked. However
the MembershipUser object returned by the CreateUser method shows that that
user is currently OnLine. I always end up with the following error message
the moment I try to call the SetPropertyValue of the first profile property:
"This property cannot be set for anonymous users."
Note that I do not want the user to be able to log in yet until their
account has been approved, so once the profile info is created I would have
to log them out and set their account to Inactive.
Thanks for any and all help.

Hi everybody,
I write a VBS script witch uses csc.exe (command line dotnet compiler),
but my problem is to detect what version of Dotnet Framework is
installed on the server to use the good repertory 1.1 or 2.0 (v1.1.4322
or v2.0.50215 ...)
What command line or script can I use to get this information ?
Thanks to all for any advice

Combobox refresh after changing displaymember and valuemember
I want to set the values for the combobox.displaymember and valuemember at
runtime. Its seems simple enough, but after changing them in response to a
change in an option group, I can't figure out how to get the combobox to
refresh itself with the new settings. I've tried the combobox.refresh()
method.
Anyone know how to get the combo box to refresh itself?
thanks

OrderedDictionary - to retrieve objects in same order
Hi,
I want to use OrderedDictionary to get my objects in same order as they
are inserted in. I also want to access the objects using a key. So my
question is whether this is the best option or there is some better
collection object than OD. The current MSDN documentation dosn't says
anything in favor or against OD for retrieving object in order.
Remember I don't want ot sort objects on keys or anything else.
Thanks in advance,

Tab Control without tab section
Hi,
Any component that work like Tab but without the all the tabs for
user to click from one view to another view. we will programmatically other
button to perform tabs view change from one to another.

because currently I using the Navigation Pane like outlook for my interface.
I think to made when user click on the navigation pane button then right
hand side pane will change to the view accordingly. I know that panel are
able to done that also, but it's very unmanaged able. when programmatically
visible and invisible those panel all the time.
Thanks for any advice in this issue.

Managed to unmanaged performance
Hi all
Existing COM ATL DLL wrapping a C++ library. Interoping from a C#
application, passing a large string containng XML (5-130kb). Need to
significantly improve performance of both the interoping and the
performance of the native functions (performance critical app).
Opinions sought on most worthwhile course of action...have identified 4
options...
1. Implement a managed C++ wrapper and link to underling C++ functions,
marshalling non-native types where necessary. Thus eliminating COM
(quick win?)
2. Re-write C++ code in C#. (no quick win, not possible to re-write all
of it also)
3. Recompile C++ code with VC7 or higher (currently VC6)...quick win?
4. Re-architect C++ code (no quick win)

error: String was not recognized as a valid DateTime
I'm facing an error:"String was not recognized as a valid DateTime"
whille accessing DateTime from webservice.
And when I try to set DateTime to the same webservice it fails with
error:"Date value is of wrong type"
it looks like xs:DateTime is not compatible with .Net DateType. Any
suggestions on how to fix this without touching the webservice (3rd
party webservice)?

way using splash screen
Hi,
Just think to get some comment from communitiy regarding best
pratice using splash screen. If we develop an application that need loading
database to dataset it's we need done it at main page fill up all nessarcy
table to dataset. since the splash screen only counter the main page loading
time. If I only loading database from second form than user will need to
wait without notification. It seen like bad experience to the user for
waiting so long of time to display out another form.
another example like crystal report. normally we will load crystal
report in from that is not the main form. mostly loading crystal report
requere alot of time to getting display out. But think in others way, if I
load all the form when the project is start then will consume allot of
memory.
So what is the best way to develop a good application.
Thanks for any comment.

Diagnosing root cause of .NET application using nearly 500 MB memory
We have a .NET application which is obviously using nearly 500MB memory and
we can't understand why. I created a dump for a different issue and the
server ended up creating a process shutdown dump of this size.

look for next i.e. the output shows

Announcement: NLog 1.0 RC1 is available!
NLog 1.0 Release Candidate 1 is available.
NLog is a .NET logging library designed with simplicity and flexibility in
mind. With NLog you can process diagnostic messages emitted from any .NET
language, augment them with contextual information, format them according to
your preference and send them to one or more targets.
The API (application programming interface) is similar to log4net, and the
configuration is very simple. NLog uses a routing table while log4net uses a
logger hierarchy with attachable appenders. This makes NLog's configuration
very easy to read and maintain.
The highlights of this release are:
* Completely rewritten tutorial featuring nice screenshots.
* Visual Studio 2005 Integration
* Ready-to-run example projects for VS2005.
* Optimized File target that can write to multiple files at once from
multiple processes while keeping the files open.
* Automatic archiving of log files (a.k.a. "rolling file" target)
* New WebService and CSVFile targets.
* Even more speed improvements in the non-logging area.
Project homepage is:

Selialize exceptions
Hi,
I creating a custom exception and I'm implementing the best practice with a
constructor which is needed for serialization (with Serialization Info info,
StreamingContext context).
My question is - whatâ??s the use for serializing exceptions when working with
web services as my remoting mechanism (for instance)? Why do I need to
provide my custom exception with a serializable option?
Thanks

CHM file with .NET
Hy!
I've got the following question in VB.NET.
How can I access to a particular topic of a CHM file generated by HTML
Help Workshop?
Some newsgroups/sites on web suggest to use CHM file for help-on-line
and the HTML files for accessing a particular topic; but I want to use
only the CHM file also for topic access, after having been generated
it, and I don't what to use the old HTML files any longer.
Do you know any suggestion in order to solve my problem? Any ideas?
Thanks! Tag: squishyTree component ASP.NET 1.1 Tag: 118397
