ASP.NET 2.0 Maintain Scroll Position on PostBack with Mozilla FIREFOX in the works?
Does anyone know if ASP.NET 2.0 is going to incorporate "maintain scroll
position on postback" in non-IE browsers like Firefox?
This seems like an often requested feature on these newsgroups since the
beta version of .NET.
Microsoft heavily advertises it's .NET browser detection advantages, why not
make some use of it and hope that Microsoft follows up their words with
actions? as well as following up on their agreement from the anti-trust
settlements on being anti-competitive.

Application Error
I have a very simpel application that fills a datagrid with data from a SQL
Server on a local network. The problem is that on one PC the application
loads fine, but on the other I get NullReferenceException in my FormLoad
Event. The connection on the failing application has a valid and working
connection to Server and I checked that the builds were the same. Does
anyone have any ideas or hints. Tag: Interface into Windows Update from .Net Tag: 87318

IDocHostUIHandler Help!!
Hi All,
I'm having some problems getting this working, i have the interfaces
defined, i have a form with a web browser control on it, and i have a web
page which i want the context menu disabled and when a button is clicked to
callback to the application throught external.SomeMethod
Now, the following code is where i am setting the client site of the
browser:
public void SetClientSite(IOleClientSite clientSite)
{
object obj = webBrowser.GetOcx();
IOleObject oc = (IOleObject)obj;
oc.SetClientSite(clientSite); // clientSite is the form that contains the
bbrowser
}
This runs fine and does not produce any errors, but the problem is that when
i right click the page the ShowContextMenu method of the IDocHostUIHandler
interface is not fired even though it is implemented in the class:
uint IDocHostUIHandler.ShowContextMenu(uint dwID, ref tagPOINT ppt, object
pcmdtReserved, object pdispReserved)
{
return Convert.ToUInt32(this.enableContextMenus);
}
And the GetExternal method is likewise not being fired.
Can anyone help, what am i doing wrong?
Thank in advance

Reverse usage of public/private RSA encryption keys for licensing?
The way that RSACryptoServiceProvider works is that we encrypt with a
public key and decrypt with a private key. This architecture works
great for people sending messages to me. However, I now have the
opposite application:
I want to put a license file on a destination computer and be sure
that it remains unaltered. It would be great if I could encrypt it
with a private key at our office and transmit the public key and the
encrypted file to the destination computer, where anybody can decrypt
it and read it, but not change it because we have the private key at
our office.
I've read posts to "simply reverse the public and private RSA keys"
but tried several variations of switching RsaParameters.D, DP, P, DQ,
Modulus and others, to no avail.
I'm sure that a solution exists, just that I do not know it.
How do I, in C# .NET, send a license file to a destination computer,
with a public key, anybody can read it, but only we can change it?

regex puzzle!
The objective is to extract the first n characters of text from an
HTML block. I wish to preserve all HTML (links, formatting etc.), and
at the same time, extend the size of the block to ensure that all
closing tags are recovered.
For example, simply extracting the first 400 characters of a HTML
block may result in an <i> opening tag being including, but its
closing tag being excluding. Or a link may get chopped halfway - [...
blah blah <a href="ht] may be the last few characters of the recovered
phrase.
Ideally, if any html opening tag is included in the first n
characters, then any number of extra characters should continue to be
extracted from the source block until all paired closing tags are
found.
We can assume that the source block is well-formed HTML, and every
opening tag has a closing tag (whether optional or not). Furthermore
(if it makes any difference), we can assume that all tags are given in
their simplest forms with no attributes (e.g. <p>, <ul>, <li>, <b>),
except for anchor tags, which have the href attribute of course.
Can anyone suggest a regular expression to do this? Tag: Interface into Windows Update from .Net Tag: 87268
Windows compound files
Are windows compound files supported under .NET?
Compound files are like a directory - there are several streams in a

files and
am having difficulty getting it to compile under .NET because some standard
windows header files create compiler errors. Even classes that simply use
IStream to
read and write themselves will not compile, with errors found in files

Anyone have info on the dreaded Q316146 bug? ... (i.e. There is no Original data to access)
I'm absolutely baffled why Microsoft has decided to give so little
information about this issue. We here (as with many other's I'm sure)
have wasted countless hours of time finding, researching and
redesigning around this issue. I wish someone would clarify
Microsofts position on this.
For example, it would be nice to know
a) Yes we are aware of it, it's fixible and is a high priority
b) Yes we are aware of it, but it would require a rewrite of
ADO.NET so it's taking a long time but a fix is coming
c) Yes we are aware of it, but it will not be fixed until .NET 2.0
d) Yes we are aware of it and it's not being fixed. good luck
fools!
Now let's analyze what this bug really means. Microsoft has banked
it's entire future on .NET (which I might add has been a success so
far). With that in mind, most medium to large size applications
utilize some form of database and DataSets, DataTables, etc... is the
new defacto way in .NET to represent this data in memory. This bug is
very easy to get as your application get's more complicated. With
this line of thinking, shouldn't this be one of Microsoft's highest
priororities!!!

Framework 1.1 Service Pack 1 Question
I am addressing this message to Microsoft directly.
Recently this service pack was released, and it has fixed many issues.
However, one glaring bug fix, for some reason or another, was left
out of this service release. The VersionNotFoundException which will
occassionally rear its ugly head when using expression columns in
datatables. This bug has been known for a while. For some reason,
the release of Framework 1.1 didn't fix it, and yet another
opportunity to fix it has come and passed. What is the deal? Does
Microsoft not know where the cause of this error is? Is it not a
priority? I have a large project which uses expression columns on a
rather large scale. The only workaround I have ever seen documented
is simply "don't use expression columns." For some of us that is just
not an option.
Does anyone have a workaround?
Will someone at Microsoft please look into this and give us developers
some advice as to how to work around this bug? Would that same person
give us some kind of time frame as to when this will be fixed. I
don't care if VS.2005 fixes it. That is years away from being a
development solution for some of us. And would that same person
please express our frustration to somebody there at Microsoft so this
will get fixed ASAP.

Dispose Question
Just a quick question on implementing the Dispose pattern.
The .NET Framework SDK documentation states that an ObjectDisposedException
should be thrown from instance methods (other than Dispose) when resources

Mistake in MSDN
Hello,
I think I have found a mistake in MSDN.
I have visual Studio 2003 with MSDN. My problem is very simple: I have a
webform with a HTML button control as:
<INPUT id="Button1" type="button" value="Button" name="Button1"
runat="server" onclick="alert('df');">
So its an HTMLServer control which does not submit.
I have this code for the button in code behind:
private void Button1_ServerClick(object sender, System.EventArgs e)
{
int h=0;
h++;
}
Now according to MSDN: (Section: ASP.NET Server Control Event
Model->Handling a Click Event in Client and Server Code)
***********************************************************************
All other HTML controls (those that do not submit a form by default)
Include an onclick attribute in the HTML syntax for the control, but follow
it with a semicolon (;):
<INPUT Type="Button" Runat="Server" Value="caption"
onclick="clientfunction();" ...>
This causes your function to be called first, before the client-side submit
script is called.
*************************************************************************
Now in my case, its always the client side script which calls first, no
matter what I do, even after using the semi-colon.The control still submits,
but first
the Javascript fires. So how can we make sure that our server side event is
executed first and than the client side script
runs (without using RegisterScriptBlock etc).
Is the above example a mistake in MSDN??

Detect IE update version or service pack number
Hi all,
I'm building a website which provides contents that only work for some
browser types and versions. I know I can get most of the client browser
information using HttpBrowserCapabilities class, but I can't find a way to
determine IE update version or service pack number. Any ideas?
TIA

Visual Studio 2002, framework 1.1 and Oracle
I have a problem and I need to know if anyone can assist in solving it. Our
database of choice is Oracle. When we attempted to do some VB.NET coding
with .NET 2002 and framework 1.0, whe had problems accessing our Oracle
database correctly. When we upgraded to Framework 1.1, the Oracle access
problem whent away, however, we can no longer use the VS Designer. We must
hand code everything. We do not want this. We want to use .NET as it was
intended. We are using Visual Sudio Enterprise Architect. We were using
Oracle 8i but are in the process of upgrading our databases to 9i. If there
is anyone with any suggestions, please let me know. Also, please feel free
to ask any questions to get more info if you need to. Thanks in advance for
any help. Tag: Interface into Windows Update from .Net Tag: 87155
Winform destructor not being called
Hi:
I'm sure this will be a very simple question to answer, but I can't see the
solution.
I am launching a modal WinForm from my main form via:
using(frmChildForm frm = new frmChildForm())
{
frm.ShowDialog();
}
The frmChildForm class is *very* simple:
public frmChildForm()
{
Trace.WriteLine(">> C'tor frmChildForm");
InitializeComponent();
}
~frmChildForm()
{
MessageBox.Show("This is the destructor");
Trace.WriteLine(">> D'tor frmChildForm");
}
My problem is that the MessageBox (and Trace) never get
called when I close the child form. Why?
TIA,
Martin. Tag: Interface into Windows Update from .Net Tag: 87153

Set culture for a DLL (class library) referenced from web application
I am developing a DLL (class library) for a web application of mine.
In the web.config of the web application I have set: culture="en-GB"
uiCulture="en" in order that the date format will be dd/mm/yyyy.
I also changed the regional settings to that date format.
When I am using the Now() function in the DLL I get the date format in
mm/dd/yyyy instead. Why the date format in the DLL is different? Shouldn't
it take the culture settings from the web application he is referenced from?
How can I control the date format of the DLL (class library)?
Thanks for your time

Scrape text from browser surface (not HTHML)
I need to do the equivalent of 'select all' and 'capture' on a browser
screen. I just want the text as it appears on-screen. Is there a simple
way to automate this?
The thing that may make it a bit awkward is that the browser windows
appear as popup-style windows, with no navigation buttons. That part
may not be so easy to automate. Tag: Interface into Windows Update from .Net Tag: 87137
