I have an editor for designing flat file layouts. The editor operates on an ExportSection, a layout specification for one text file, as its model, using a DataGridView as a presenter for the line layouts in the section. It has section header and footer groups, which appear before and after all the export lines, respectively. It also allows a single group header and footer, which appear before and after each set of records in a group, e.g. line items per invoice number. Each section has 0 to many lines.
Now I have various commands for the user to edit the file layout, and I would please like some suggestions as to making these commands as intuitively accessible to even very novice users. At the moment I only have a top menu bar, and some ugly, un-iconned buttons at the top of the editor. The command set is:
Main Section Menu.
1. Insert section header.
2. Insert group header.
3. Insert group detail.
4. Insert group footer.
5. Insert section footer.
Once a user has created the groups they require, e.g section header and group detail for a simple file, they can add more lines to a group by highlighting a cell in that group, and clicking the Add Line button. The other operations that are then available are:
1. Move cell left.
2. Move cell right.
3. Move line down.
4. Move line up.
5. Insert a column right of the current column.
6. Insert a column left of the current column.
7. Delete the current column.
8. Delete the current line.
9. Cut copy and paste cells or whole lines.
I want to use some sort of view that e.g. for commands 1 to 4 in the second list, I'd like a Move panel or something that nicely groups all the move buttons or menu options, and the same for inserts and deletes. I need something instantly visible and accessible to the users, in addition to having these commands available on right-click context menus. I'll probably end up designing my own icons for the buttons, but I'm not sure if simply buttons is the way to go. I want to find something newish, maybe a ribbon (gasp) or something that displays command sets based on context. Any suggestions at all would be welcome.

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
