Hi,
How do I decide whether I've to use a Windows scheduler or a Timer to run a process.
i.e, I have a windows form, which writes an XML file after querying our Database at pre-set interval. What should I use in this scenario, a Timer control (System.Timers.Timer) or a Windows service to run this process?
Regards,
Blumen

What about using the actual Windows Scheduler to fire off your application? Using a timer (System.Timers.Timer) means your application is running all the time and using computer resources. Then you have the problem of monitoring to ensure it is still running (often called heartbeating). This applies whether you have a form running with a timer to kick off the query or a Windows Service to do it. Windows Services are really meant for applications that need to constantly monitor for events (such as files arriving), again using a tmer means you need to check the application is still running, it will be using resources etc.
I hope this helps.

Hi Bob,
Thanks for the information. My application would be periodically querying employee database and creating xml files if new employee is created.

You are welcome. If you are periodically checking the database, depending on the frequency, I would probably go for a Windows Service. You need to consider the frequency of check and cost of starting the application.
Hope this helps

The desktop support guys here have asked me to put together an application that can display info while a screen is locked (mostly XP machines but a few Vistas as well).
So far I'm only aware of 2 ways of interacting with a locked machine: the background image (like bginfo) and under certain conditions using extended keys (such as the volume keys on some keyboards).
I'd like to use a combination of the 2 (i.e. press an extended key and change the background image with the required data) but I can't guarantee that every user will have an extended keyboard or that their machine configuration will even allow this.
Does anyone know any other ways of interacting with the machine while the screen is locked? Lateral thinkers welcome!!

How about setting up the machine to show a screensaver, which will show while it's locked, and the screensaver can respond to key board events to show differnt things ?

Good idea, the only caveat being not everyone uses a screensaver (I just blank my screen after 5 minutes).
It looks like I may need to implement a suite covering all possibilities.

You could make you program change the screen saver settings, and if necessary, change the power options to not turn off the monitor(not good for laptops on battery).

The DataGridView has a CellValidating event which is raised when a cell loses the focus. If you take a look at the MSDN documentation for it, there's a sample that shows how to validate the entry. The example looks at validating for an integer, but if you use double.TryParse instead it should do what you want.

Did you try this one??
Me.dataGridView1.Columns("xxx").DefaultCellStyle.Format = "c"

.NET 2.0 - I need to display a "promptString" with different characters for specific positions in a MaskedTextBox, rather than just the same character repeated (e.g. HH:MM). May need to use TextBox with RegEx validation instead.
Is there an easier way?

Isn't HH:MM different characters for specific positions? What are you talking about?

Thanks for responding.
The MaskedTextBox control has the PromptChar property that allows the default "_" or any other single character to be used in a prompt string (based on the contents of the Mask property). All that gets displayed is "__ __". I'd like to see "HH:MM". Or in the case of a LAT/LON entry, "##A ###A".

 If I ever used it I would know that!
Did you consider using a tooltip to present the "HH:MM" string. You could include additional explanatory information as well yes?

Thanks, but unfortunately the requirement is to display it as the prompt.

In order to write to an excel sheet you can use either excel object model or excel oledb provider. There are many articles available on codeproject and on google.

Hi all,
I’m a C++ developer and a very beginner in both C# (.Net) and Word Programming. What my company wants next is something like this: from different texts to build a Word 2007 document and then open this in the real Word 2007 application to give the user the possibility to change the document as usual with all possibilities (Menüs, Panels, etc.). Well my problem is that the Word 2007 must be embedded in our C# - Application (WinForms).
Knows somebody a solution to do this: embed the Word 2007 application in WinForms or if better maybe in WPF? For any idea thank you in advance.
Best Regards,
Emil
