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?

My reference to the MS Access database file is as follows :-

Do I need to change any of this syntax or is there some other reason why VB10 won't show anything ?

I need to extract specific data from a database. With starting point in this data, I will collect information on the internet. After the information is collected I need to check if this information is already stored in the database, and if not, then add it. This action is being repeated about 500-50000 times each time the procedure is being executed. (not often)
The approach I'm taking seemes sleazy and ineffecient and I was hoping you could point out some places where I might be able to optimize it. I've two open connections at the same time. The first I use to extract data, and it stays open throughout the whole session. The second connection is being used first to check if an entry already exist and if not, to add the data.
The reason I am using two connections is due to the fact that I got a reader bound to the first one, so it is rendered unavailable.
I was thinking that maybe checking if the data existed, and adding it if not, maybe could be contracted into one command execution instead of two. I don't know if it would be possible to do this with one connection only as well, as it seemes more proper.
I am looking for the code to consolidate multiple .xls sheets from within multiple work books in a file all containing the same format of information. Each sheet needs to be coppied to a new sheet within a single work book.

I need to create an excel file from scratch in VB.NET given a DataTable from asp.net. I can do this for a specific file, but I don't know how to do it for a general database. That is, where I use the "CREATE TABLE ..." I don't know how to tell it what types to use for the data in the table.
The DataTable is derived from a FoxPro database. (I don't know if that matters.)
I invoke the table similar to as follows:
<%
return_value = make_excel( sql_table, excel_filename)
%>

What I need to be able to do is run through the values in sqlTable above, check their type and then build the sql to write them.

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
View 2 RepliesI am reading in data from an excel file that is only viewed inside the program. This excel file is being populated by data from multiple PLCs (7) through DDE links via RS Linx Gateway. I would like this data to be written to two different excel files and specific sheets within those so that it can be viewed later on.
My program has a form that will allow the user to view the data live, meaning they look at the first excel file from the program so that they are not able to edit the DDE links or change the file in any way. The other excel files (there will be two, one for good parts, one for bad parts) have specific sheets for each part and each tester station. For example, if the part is a ABC part, and it is a good part, and it was tester on tester station 1 then it needs to be saved to the good parts excel file, in the ABC sheet and in the good tester station 1 sheet.
If part XYZ comes along and is a bad part (fails testing) then it needs to be saved to the bad parts file, the XYZ sheet and the bad tester station 1 sheet.I might have added more detail than is needed to solve the problem but I thought I would add it anyways to help you all understand my problem a little better.
