There are classes that allow you to write to the event log. However, if you want a proper log component you'll have to look for things like log4net or the Microsoft Enterprise Library Logging Application Block.

Seconded on log4net. Very easy to get up and running.... or logging.
|

Thanks Mark,
Microsoft has no built-in Log function?

Well we went with log4net because it had some features we wanted to use in the future. Firstly we had it logging to SQL server, but then we got it to shoot out UDP packets for high priority log entries to a remote console (in another country)!
You can log to the windows event log using (it think) classes in System.Diagnostics, thats quite easy to get working.

Thanks Mark,
What means *shoot out UDP packets for high priority log entries*? Why using UDP for high priority? What packages do you use for normal priority log -- TCP?
regards,
George

Ah sorry to be confusing. We log everything to SQL server. High priority messages (non sensitive) get stuffed in a UDP packet (theres a UDP log appender for log4net) and sent to my laptop. I run a program on my laptop that pops up - so if anything serious is going on then I know about it.
As for UDP/TCP... UDP is a little more convenient than TCP, as there is no connection setup. You can just stick a packet with a destination address out on the wire and it will (probably) get to the destination

Hi Mark,
You mean UDP transmission is faster then TCP, right?

George

Thanks Colin,
You mean Microsoft .Net has no built-in log function? What is *Microsoft Enterprise Library Logging Application Block*? Is it easy to use? I only want to write to local file, no complex function needed.

Here's[^] a simple-minded logger that may meet your initial needs.

Thanks Ravi,
Seems it does not provide function to limit the size of log?

From the help file of ConnectionState enum type:
Broken The connection to the data source is broken. This can occur only after the connection has been opened. A connection in this state may be closed and then re-opened. (This value is reserved for future versions of the product.) <br />
Closed The connection is closed. <br />
Connecting The connection object is connecting to the data source. (This value is reserved for future versions of the product.) <br />
Executing The connection object is executing a command. (This value is reserved for future versions of the product.) <br />
Fetching The connection object is retrieving data. (This value is reserved for future versions of the product.) <br />
Open The connection is open.
I'm using .NET 2.0. Does this mean that the values "Broken", "Connecting", "Executing" and "Fetching" are useless?
Does .NET 3.0 or 3.5 changed this?
Thanks.

in a text box which accepts only numbers ,when the user tries to input a alphabatical character ,i want to ignore the key stroke ?
|
|
|
|
|
Why not use a MaskedTextBox?
|
|
|
|
|
You can set up an event handler for keypress event to check whether the key that was pressed is digit or not. Depending on that you can ignore the key if it isn't a digit or a backspace

Showing dynamic images in crystal reports would be a hectic problem. Passing image name and showing it over there is not possible. One option would be storing image in database as BLOB. Crystal reports having capability to render this BLOB data. But for this you need to switch your DB to SQL Server.

My application will generate a word document as report. The application created Word Application and Document objects.
When users click on Close or the "X" icon on the up right corner. The application will intercept word DocumentBeforeCloseEvent, to ask users Save, No or Cancel to the document changes. Everything works fine except when users click on "Cancel", Word still displays it's own Dialog for users to select Yes, No or Cancel for saving the document changes.
Is there anyway to prevent this Word dialog because my application already process uses decision?
Here is part of the code:
Word_DocumentBeforeClose is used to process users decision.
The last part of If in else is to process when Cancel is clicked.

Hey,
I'm having some problems starting a command-line program using Process.Start(). I pass it the filename and arguments, and it runs the program, but instantly crashes and a "Program has stopped working" error comes up. I can't figure out what is wrong. The program runs fine from the command line and when I use a shortcut, and Process.Start() runs other programs fine. Can anyone tell me what is wrong?
For reference, I am running this in Vista.

As per my experience you have problem in passing arguments.
Try without argument passing, and change the way to pass arguments.
Hope you will find solution.
I have tried to give hint to your problem.

Well classical problems like this are solved by using unmanaged code equivilant to the System.Diagnostics namespace from the win32 api.
(Hint: search MSDN)
Hope this helps!!;)

I inherited a program that takes data from a csv file and inserts it into a database.
The data is in the following format:
8/20/2007 12:14:21 PM,HDFM,"Nick Yockell","Nate Wittrock",239-850-3931,239-850-2514,"Used 2004 Harley Davidson ","bought bike
CUSTOMER WANTS TO BRING HIS YAMAHA R6 IN TO TRADE AND SEE HOW MUCH PAYMENTS WOULD BE.
",Deliver,aa32ed31-f0c8-4f43-a7d4-830d9f29edcd
For some reason the function that saves the data to the database is having a problem with the customer phone number (5th column).
The database column is a varchar(50) - the same as the customer business phone number.
If the customer home phone contains anything other that digits it cannot be saved to the database.
However, the customer business phone can contain anything and gets saved just fine.
Is there anything in the two functions that could be causing this ?

I had read your code, i think it works can you give me the error.
In above code there is no error.
