- ADO >> TransactionScope exception handlingIs there any way to have an DataReader.Read part of a TransactionScope but not cancel the transaction if the read fails?
I'm using a DataReader to get the result of a stored procedure which increments a counter. I'd like to add the read to
the transaction only if the read is successful. If the read isn't successful I don't want it to cancel the entire
distributed transaction but I will need to roll it back (since the SP updates a table) if some other part of the transaction fails.

- Net Framework >> LinkDemand ErrorHello,
I have a class that implements the interface IMessageFilter. When I run
FxCop on this class the following error appears:
The virtual method IMessageFilter.PreFilterMessage(Message&):Boolean
defined by type 'System.Windows.Forms. IMessageFilter' and its override
MessageFilter.PreFilterMessage(Message&):Boolean do not have the same
LinkDemand status. Add a LinkDemand where required.
I have placed the folloing code:
[CustomPermissionAttribute(SecurityAction.LinkDemand)] but still have
the same error. I tried with the
[CustomPermissionAttribute(SecurityAction.LinkDemand),
Unrestricted=true] and also with Unrestricted=false but nothing, same
error.
Can someone tell me what I do wrong.
Thank you.

- Visual C#.Net >> Providing a programming interface to a pluginI was quite surprised to find virtually nothing about this but I may
have been searching for the wrong thing.
I want to know the best way to provide a programming interface to a
plugin. I already have a plugin architecture that allows the
application to call code in a plugin but I want the plugin to also be
able to call code in the application.
I can think of many ways to do this but I am not sure the best way:
Option 1:
The plugin inherits a class that has one function called
GetInterface(), This returns a reference that can be cast to different
Interface types.
Option 2:
The plugin is passed a reference to the application interface which
contains all the callable functions.
Option 3:
The plugin can create an object that has all the API functions in it
e.g. Stop, Pause and Play. (The problem with this is how do you
actually connect those functions back to the main application.) I
suppose this would be similar to the office api or activeX interfaces.
I want to choose the best way that will also allow me to update the
API without breaking any existing plugins.
Any advice is welcomed!

- Visual C#.Net >> DataView - Integer SortingHi All,
I have used gridview in my application and i m using dataview to sort
the grid. But when i sort the numeric column, dataview sorts it like a
string.
So, after sorting, instead of getting 1,3,11.... i get 1,11,3... in asc
and 3,1,11 in dec..
Anybody has idea regarding this???

Mansi Shah.

- Winforms >> MSDE & Auto IncrementHiya all,
I'm not exactly sure where to be posting this question, but here goes &
hopefully someone can answer it or re-direct me.
I'm building a windows form application in C#. I am using MSDE I've imported
my Access.mdb & set up the Identity, Identity Seed, & Identity Increment. I
want to be able to add a new entries (rows), but the problem arises because
update won't work until I input a number or update my ID field first. I
don't want to see this ID field on my form that is being incremented or to
have the user deal with inputting this number. When I manually (directly) go
in and add data to my field, the ID field does not update till I insert text
into the next row (another new row) following it. This problem does not
happen when I directly access access.mdb itself.
The following is a sample of my code which seems to be correct as does my
Identity, Identity Seed, & Identity Increment :
DataRow thisRow = dsAddError1.Tables["Error Log"].NewRow();
dsAddError1.Tables["Error Log"].Rows.Add(thisRow);
sqlDataAdapter1.Update(dsAddError1, "Error Log");
Any and all suggestions tips are appreciated. Thank you all in advance.

- Visual C#.Net >> visual studio problem with comment web pagesHi. I am just running through the hello world tutorial and when I attempt to
generate the comment web pages (like javadoc) it just creates a page with no
content. Um....this is the tutorial and it's really hard to screw this up.
But I managed somehow. My source file is exactly as shown in the book and I
honestly can't see what I could possibly have done wrong, other than some
obscure configuration info somewhere set wrong.
Anyway, if anyone knows what may be amiss, I would appreciate a tip.
Thanks,

- Visual C#.Net >> Persisting Application Scoped SettingsWhat what I have read, Application Scoped settings in the setting file
are read only. Why is this? Is there a good reason for this
restriction?
I understand that some settings will be different for each user of the
app, hence the User Scoped settings. User scoped settings can be
changed and persisted at runtime.
But there are also settings that are not User Scoped (i. e.
Application Scoped) that still might need to be changed at runtime,
yet this is not possible. Why? Again, is there some good technical
reason for this restriction?
What alternatives are available to me to be able to persist
Application Scoped settings?
Thanks,
Chris

- Dotnet >> Process.StartInfo.EnvironmentVariables problem when there are twoexample code:
public class envtest
{
public static void Main()
{
System.Diagnostics.Process proc =
System.Diagnostics.Process.GetCurrentProcess();
string env = proc.StartInfo.EnvironmentVariables["test"];
}
}
when I compile that code to envtest.exe
and before running it set some env variables that differs only in letter
scope, i.e.
set test=1
set Test=1
I recieve following exception.
Unhandled Exception: System.ArgumentException: Item has already been
added. Key in dictionary: "test" Key being added:

at env.Main()
Unknown signal 79
I can catch it but I still cannot get variables value :(
Any idea how to handle that ?

Dotnet >> Content missing from pages - CMS2K2
I posted this in the CMS newsgroup and it was suggested that I post it here.
Here's the problem:
I have a problem where an entire page of information disappears from an
intranet website. The website uses Microsoft CMS2K2 and is installed on a W2K
server w/SP4. All other pages on the site are accessible. The event logs show
the following errors:
Event ID: 0
Exception in ActiveDirectoryManager::GetEmployess2(), before
for--System.Runtime.InteropServices.COMException (0x8007203A): The server is
not operational

at System.DirectoryServices.DirectoryEntries.GetEnumerator()
at
Mywebsite.IntranetCMS.BusinessServices.ActiveDirectoryManager.BuildEmployees(DirectoryEntry

at
MyWebSite.IntranetCMS.BusinessServices.ActiveDirectoryManager.GetEmployees2(ADEmployees
objEmployees)
Event ID: 0
Component: Compaq NIC Management Agent Error: Unable to open the registry
key "%1". Cause: This error can be caused by a corrupt registry or a low
memory condition. Rebooting the server may correct this error.
If I reboot the server or restart the service the data on this page
re-appears but not for long. It's only happening on this one page.
Anyone have any ideas on how to begin troubleshooting this?
TIA

- Net Framework >> EndInvoke still required?I've read a lot of comments from the 1.1 framework era about a page of the
documentation that claims you have to always call EndInvoke on an
IAsynchResult.
Various comments I've read suggest that this wasn't strictly required in
the current implementation (1.0 and probably 1.1) but that the runtime team
reserved the right to leak if you didn't call EndInvoke.
I've been looking through the 2.0, 3.0, and 3.5 documentation and can no
longer find this reference. The Asynchronous Programming Overview page no
longer says anything about this being a requirement, and the BeginInvoke
method doesn't mention anything about it.
Is EndInvoke still a requirement? I've read elsewhere that the the
framework team has guarnateed that BeginInvoke won't leak, so it's a bit
confusing.

- Net Framework >> Re: Treeview and ListviewAlbert,
I have a question: why is your timer not working when your form doesn't
have focus? In my opinion, it should keep working fine. Are you getting
some sort of exception? Can you shed some more light on your
implementation? Perhaps you could post some sample code. Are you
building a MMC plugin, or is this a pure C# WinForms application?

- Dotnet >> Run RCMD on VB .NET program problemHello all,
I have the urgent problem. Pls help me.
I have written VB .net program to fax PDF document. The program hasn't
screen interface and runs in Command Prompt.
Here is some program segments.
faxserver.connect(LocalComputerName)
faxserver.createdocument("c:\test.pdf")
...
faxserver.send()
That's ok when I run in local computer Win2000 Server.
But, I can't run it remotely. I use RCMD.
RCMD \\ServerName "C:\FaxProgramName Param1 Param2"
There is no error code prompt. I can see the program process in server
computer. I have created and used the same username account both in server
(Win 2K server ) and Remote computer (WinNT WKS) with the administrator
right.
Thanks in Advance.

- Winforms >> Threading, InvokeRequiredI have an exception handling procedure which displays an error message
to the user. This is done by creating an instance of the custom form
ErrorDisplay and showing that instance as a modal dialog, parented to
the main MDI window. The code is as follows.
Private Shared Sub DisplayExceptionMessage(ByVal ToDisplay As String)
Dim frmError As New ErrorDisplay(ToDisplay)
frmError.StartPosition = FormStartPosition.CenterScreen
If frmError.ShowDialog(MdiParent) = DialogResult.No Then
Application.Exit()
End If
End Sub
This procedure normally runs on the main thread, however I have
recently introduced multithreading to the application and am now
finding that it will sometimes run on one of the worker threads I have
created.
The problem comes when showing the error form as its behaviour is not
exactly the same as when the procedure runs from the main thread. I
believe this is because the MdiParent variable, which is a reference to
the app's MDI window, was created on the main thread and frmError on
the worker thread. I probably need to use the Control.Invoke method
here but can't quite see how. This theory is backed up by the fact that
MdiParent.InvokeRequired returns true when running on the worker
thread.
Any suggestions would be gratefully received.
Thanks,
Ross

- Microsoft Project >> Windows SharePoint Services and Project 2003Hello,
One of the gold certified partner got the below error
while installing Windows SharePoint Services for Microsoft
Project Server 2003 on Windows 2003.
Error: Share point configuration wizard cannot create the
ms_projectserver_publicdocuments site with the template
you have selected.You must use the project workspace
template or any other template you have created by using
the project workspace template. Ensure that the template
has been installed into the correct directory and that run
share point configuration wizard again.
After a while he wrote the below mail stating the problem
is solved :
Alex,
I made two changes and seem to have resolved the problem.
1. I ran PSCOMPlus.exe and changed the accounts to
domain\administrator - that resolved an error that I got
trying to get WSS Admin COM+ to run properly.
2. When running the sharepoint config utility I added
the domain to the user name (domain\administrator) and ran
the wizard.
One of these two things resolved the problem.
If you could just reply with your observation and view
explaining which option would have solved the problem
could be quite helpful. (Any relevant kb article)
Thank you very much for your help.
Alex Mathew
