I am experienced VBA programmer and I want to expand into Visual Studio 2010 (Express version at the moment, bacause it's free). What I need is some code samples to get me started. Possibly showing all relevant aspects. Here goes:
A form has products as icons (in ListView?) - ordering is done by drag and drop onto a basket Products will have color and size - selection is done by two TabStrips or similar feature ( if TabStrip control is still available in ViStuEx2010)Database might be Excel sheets if possible, but other free options are OK (if Excel can cooperate with ViStuEx2010). How about XML residing on the Web? SkyDrive?
Menu and starter of the application might be from Excel too - but I'll be glad to learn newer ways - code needed for both options: when Excel is a starter and compiled ViStuEx app. is a starter.
I imagine that many people write order taking applications using drag and drop interface.
When working with Excel in this context, is there a way to get the Excel Application/Workbooks/Sheets events?

The job runs but not put all sheets in tha same workbook.
CODE:
What I want to do is have data rows on the first sheet that is basically a master list, then have the sheets behind it display the data rows that meet a given critera.For example, sheet 1 column 1 has a person's name, column 2 their phone number, column 3 their address. Column 4 has 'M' or 'F' designating wether they are male or female. I would then like to open sheet 2 and all the entries marked with 'M' are automatically produced and display all the information for each person. I also need to "change the gender" of the person and these changes are also automatically changed on sheet 2. I'm guessing it may be a combination of filtering and macros but have no idea how to execute it

I have to provide an Excel file as an output. I have to color some of lines and make them bold.The input is based on a dynamic list (in memory) and it also could be based on CSV file that I'm already provide today (based on the same dynamic list).I'm wondering what would be the most efficient way (in terms of performance) in order to provide the colored Excel output?Should I export directly from dynamic list into Excel - or - Should I export from CSV into Excel ?
