- Visual C#.Net >> custom logging sink for logging application blockI have written a custom logging sink for the enterprise library logging
application block (June 2005). I have been able to configure it as expected
from the UI config tool (EntLibConfig.exe).
I have built a console application to test it with and I am getting the
following error message write to the default trace log when I attempt to use
my custom logging sink.
'An error occurred while the Distributor was processing the message. Please
check your configuration files for errors or typos. Verify that your sinks
are reachable (queues exist, permissions are set, database exists, etc...)'
This might be security related can anyone give me the answer on how to fix
this?
I can see from VS that the module for my custom logging sink is loaded at
runtime but I am unable to break into the assembly which indicates to me
that any of the 'LogSink' overridden methods are not being called.

- ADO >> Macro to Generate OleDbCommand for a Stored Procedure callAfter searching for just such a macro/tool, I decided to write one
myself. After writing one myself, I decided to post it for others who
might be searching as I was:
Here's the macro. Since clipboard access is not available in Visual
Studio Macros, it's based off the current selection. What I do is
select my stored procedure code in Visual Studio and run this macro.
The output is put into the Output window pane, and I copy and paste it
from there. It's already saved me hours and I only wrote it
yesterday.
Sky's the limit on customizing this thing. Just please let the world
know if you make some sort of massive improvement. It's just a Macro,
so make all the changes you want to suite your coding style, etc.
By default, if uses a connection object named "conn" and it calls
"ExecuteNonQuery". Also, as you can see, it converts the T-SQL types
that I had immediate need for to OleDbDataTypes. Add as needed. Go
to town!

- Visual C#.Net >> OO AnalysisAlright, I've read Jesse Liberty's book almost cover to cover. So now I
know something about using C#. I have an idea for a program I want to
write.
I have NO IDEA what objects I need, or how to set things up. Are there
any good object-oriented books or website tutorials on ANALYSIS that you
would recommend? I need something that will teach me to diagram and
organize my thoughts.
The program I want to write transfers certain files and directories from
one PC to another. It seems I need a source computer object and a
destination computer object. Beyond that, to what level should I
extrapolate objects? Should I have a log object, for instance? Surely,
I wouldn't have an object for each program I want to copy (I was
thinking of doing an enumeration for software). I need to know where to
draw the lines.

- Winforms >> A Newbie QuestionHi All,
I'm trying to develop a prototype for a small Room Booking application. This
is a 3 tier application. The presentation layer consists of Windows Forms.
There will be multiple concurrent clients. The application needs transaction
supportivity.I thought of developing in .NET C#. The data base is going to
be SQL Server 2000.
I thought of following the design guidelines mentioned in the
MSDN,Application Architecture for .NET Designing Applications and Services
from Microsoft
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html
/distapp.asp).
I have some questions. For my distributed application which technology would
be best suitable?. Enterprise Services COM+ components or .NET remoting or
Web Services? How can I take the decision? My application needs quick
response (Speed is important).
Thanks in advance.

- Visual C#.Net >> Create a string of n pixel width...Since I have no control over a treeview's scroll bars (i'm drawing icons
and text to the right of the treenodes) I've decided to just add some
special text to the end of my tree node text which I will then strip out
when it comes to drawing the treenode into the treeview...
Anyway I know there is a way to get the pixel length of a string that
already exists, but is there a good way to create a string of characters
that are a certain length? Should I just have a function that loops
adding 'x' until it's a certain length? Since this will only be run
when a node is created or when a node's special properties change I'm
just planning on doing this - unless any of you know of a better solution.
Thanks,

- Visual C#.Net >> OOD QuestionThis is a design / inheritance qus.
I have class Task.
This is a base class for some specific tasks
Say
WorkOrderTask : Task
TimeSheetTask : Task
Now Task has a function GetDetails() which gets all info about task. This
makes a database call.
I override this in the derived class. For implementing this in derived
class i see following 2 approaches.
Approach 1. WorkOrderTask .GetDetails()
{
Calls base.GetDetails(); to get base details, populates in the
object
Gets details specific to WorkOrderTask, populates in the object
returns;
}
Approach 2. WorkOrderTask .GetDetails()
{
Get details specific to WorkOrderTask as well as the base class
details, populates in the object
returns;
}
The problem with
Approach 1
I have to make 2 database calls.
Approach 2
If theres some change in base class I need to take care of these in all the
derived classes as well.
Whereas, Approach 1 is advantageous here as by modifying only the
Task.GetDetails funciton ( this is the base class ) function i have all the
values and i do not need to touch the derived classes.
Was thinking this might be a very common problem, so perhaps many of might
be able to guide me on the approach i must take here. Perhaps anything other
then the two i have talked about.
Thanks in advance

- ADO >> Batch Update ProblemHi,
I am porting an ADO.NET 1.1 project to version 2.0 and trying to take
advantage of the dataAdapter's UpdateBatchSize property. When I set this to
0 and change my updatedRowSource to either NONE or OUTPUT PARAMS, I get the
following error when trying to update more than one row.
5/10/2006 12:52:18 - Exception occurred ---> Description:
ExceptionHandling.CustomException: The ConnectionString property has not been

My update method is as follows. I initialize the data adapter's update
related sql command objects' connections at run-time. (I am not using
'USING' as I want to catch exceptions)
Private Sub DoUpdate()
Dim cn As New SqlConnection(strConn)
Me.dataAdapter1UpdateCommand.Connection = cn
Me.dataAdapter1DeleteCommand.Connection = cn
Me.dataAdapter1InsertCommand.Connection = cn
Try
Me.dataAdapter1.Update(Me.Ds.dtMyTable)
Catch ex As Exception
LogExceptions(Me.Name, "DoUpdate", ex)
MessageBox.Show(strChgError, strSrvrError, MessageBoxButtons.OK,
MessageBoxIcon.Error)
Finally
cn.Dispose()
End Try
End Sub
Can anyone tell me why this happens and how to fix it. I can correct the
problem by setting the updateBatchSize to 1, and the problem does not occur
when only one row is being updated. I am connecting to SQL Server 2000 SP4.
Thanks.

- Dotnet >> Strange, intermittent "Configuration Error" involving a COM DLLI have a Dot Net project that references a COM DLL called
"Crypto.dll," which is registered on my machine. I added the reference
via the "Add Reference" dialog in Visual Studio Dot Net, and I am
successfully accessing methods in this DLL in some of my classes.
"Interop.CRYPTOLib" is the name of the interop VS.NET created for me

Frequently, when I try to run my application, I get the error that

What's very frustrating and puzzling is that sometimes this error
occurs and sometimes it doesn't; it will occur 10 times in a row, then
I'll walk away from my desk for 15 minutes, and the application will

Rebootimg my machine always seems to fix the error, but only for a
short period of time; it always recurs eventually.
Any help that anyone could give me on this would be greatly
appreciated...I'm really stumped! Thanks in advance!!

- Winforms >> Tab key in a datagrid on a modeless dialogHello
I have a datagrid on a modeless dialog and when the focus is on the datagrid
the tab key doesnt work. Now, I understand that when you have a modeless
dialog then there is some kind of message loop missing and that is why the
tab key doesnt get captured. That is why I though I could inherit my own
datagrid and override the ProcessKeyPreview to capture the Tab key. This
only works with the Enter key though. The Tab key never gets sent to the
DataGrid. Does anyone know where the tab goes? Do I have to use the textbox
column in some way to get hold of this one. I also wonder why the Enter key
is seen by the datagrid but not the Tab key.
Thanks for any input

Net Framework >> Debugging a server app
Hi,
I am having the following event logged when I try to debug a COM+ server
application:
"The server {54AD3709-9B43-42A8-B896-404FDCF4AC85} did not register with
DCOM within the required timeout"
I also get a dialog box saying "An error ocurre while processing the last
operation. Error code 8008005 - Server execution failed. The event log may
contain additional troubleshooting information".
And all I am doing is:
I go to the Component Services Explorer and I Start the COM+ application.
This opens an instance of VS.NET 2003 containing dllhost.exe.
My intention is to be able to debug the components in that COM+ server app.

Net Framework >> Debugging a server app
Hi
If you are running the ServicedComponent as a COM+ server app, it will
running in the dllhost.exe, another process different from the client
process.
To debugging the SC, you can attach to the process when the dllhost is
lauched, and then call into the SC from client, the debugger will stop if
there is any breakpoint hit in the SC or exception occur.
Also from the KB below.
While debugging, a transaction may time out before it is committed or
aborted. To avoid a timeout, use a timeout property on the transaction
attribute. In the following example, the associated method has 1,200
seconds to complete any transaction before it times out:

database was corrupted, they informed us that they had just upgraded to XP
SP2.
We upgraded the developemnt VPC to SP2 and this throws a message to say

switched the firewall off but this makes no difference.
We are using the JRO.JetEngineClass method to do the compaction.

MVP's and experience programmer's only please!...
I need to get the number of lines in a textbox so I can insert them into a

When the user changes the column size then I reload the lines accordinally.
The problem I am having is when I get the lines property which is a

Now lets say I wantet to update my data-access layer to use standard ansi

to update only a single .dll on a client server without the project crashing
miserably.
I have tested this idea, but I can't get it to work. When I overwrite my
existing data.dll with a new one my businesslogic layer crashed with the
error:
The located assembly's manifest definition with name 'Minas.Data' does not
match the assembly reference.
How do I solve this? There has to be a way.... either by using another
architecture from the get go, or my some other means ... I cant't see the
point of splitting the layers into different projects in visual studio if I
can't update them seperately...
Am I missing something? Is there a better way of solving my problem?

1. Start at the beginning of the text file
2. Read in 100K of text
3. Work with the 100K of text
4. Repostion the cursor to the start of the next text block (position now
100001)
5. Read in 100K of text
6. Work with the 100K of text
7. Repostion the cursor to the start of the next text block (position now
200001)
8. Read in 100K of text
9. etc
I'm thinking that I need to use the StreamReader.Read function. Is this the
best approach? What approach will be the fastest?
Thanks very much

- Net Framework >> Compile warning???Hi
When i compile my app i get the following warning... not sure how to get rid
of it. I have removed and added my 'Reference' back in but it didn't change
anything.
Warning: The dependency 'MyDLL, Version=1.0.1672.16368, Culture=neutral' in
project 'MyApp' cannot be copied to the run directory because it would
overwrite the reference 'MyDLL, Version=1.0.1706.30700, Culture=neutral'.

- Dotnet >> Help with the magically instantiating collection classHi everyone,
I posted a question earlier about a collection class that I'd made seemingly
getting instantiated magically after a class that contained a variable of
that type had its constructor called.
The constructor didnt touch the collection class and defineately didn't
initialise it.
Some one suggested the following reason as what is happening.
If anyone can help with what I've said down below i'd be very greatful:
Thanks

I'm not really sure what to make of that. How come, if I dont initialise, by
means of a constructor, a string for example - its null until I give it
something?
Thanks
