I have built an Access 2007 database with some data stored in it. I have managed to export data using VB2008 from that database to Excel 2007 and have it automatically draw charts based on this data and a query in the Visual Basic Code. One of the results looks like this:
View 3 RepliesI have a datatable in memory (a flat file, no primary key or relation to other table) and I wish to make a pivot table in Excel out of it. I have been using the Excel COM, so I am hoping that there is a way to do it this way. I have seen code that will put data in a pivot cache via an SQL connection string, but I have yet to find anyway of using a datatable as is.

I am creating pivot tables in VB.NET and have run into a problem I did not think would be as difficult as it is turning out. When I create a pivot table it adds in subtotals for each row and I do not want that. In excel you just drag down the subtotals option and tell it to not display subtotals. I looked into the VBA for it and it is several lines long of this format:
ActiveSheet.PivotTables("Main Highway Pivot").PivotFields("Division"). _
Subtotals = Array(False, False, False, False, False, False, False, False, False, False, _

I'm trying to generate a pivot table in Excel using VB.NET 2008. I need to bring the data into one tab, and then generate a Pivot on another (i can't do this externally because the data is pulled from a bunch of different places). Currently I'm doing this pivot in the actual code, and then writing to Excel, but it takes up a lot of resource and time and this will make things much easier! I created a sample list below, and I am trying to generate a sample pivot table based on it, but I'm getting errors:

How to create a pivot table on an Excel spreadsheet via code. The reason I took so long is because I added a reference to the Excel Interop 12.0, rather than the Excel Interop 11.0. I assume that 12.0 is for Excel 2007, while 11.0 if for 2003 (or whatever I have). If that assumption is correct, this will cause me a bit of trouble, as all the people using the program are in the process of moving from 2003 to 2007, and I should have moved myself, but didn't for some reason unknown to me (I thought the upgrade was pushed out to my computer when I was at work, but I don't seem to have it anymore). However, my concern is that the objects needed to create a pivot table in the 12.0 library are significantly different from the objects needed to create a pivot table in the 11.0 library.
I don't believe I can late bind to solve this, because there will need to be different steps taken depending on the version, since the objects have different interfaces. It appears to pertain only to pivot tables (for what I'm doing), as I was able to create the workbook, the worksheets, and export all my data with some old code that I had, and all of that worked with both libraries, the difference is just with the pivot tables because the interfaces have changed, such that the methods needed for one library don't even exist in the other one (and the code crashes, but that's probably because I have the PIAs for 2003 installed, and not 2007).
I want to change the source data for my pivot table in Excel using VB.Net to a named range.
I have : table.ChangePivotCache(wb.PivotCaches.Create(SourceType:=Excel.XlPivotTableSourceType.xlDatabase, SourceData:=sheet.Names("name_of_NamedRange").RefersToRange))
Exception : The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
I have three tables, the extremely simplified versions of which are:
Practitioners:
practitioner_id :: int
name :: nvarchar
Insurances:
insurance_id :: int
name :: nvarchar
InsuranceLink:
practitioner_id :: int
insurance_id :: int
So, the practitioner table contains a list of practitioners, the insurance table contains a list of insurances, and the link table represents which practitioner supports which insurance. Now, I need to create a view which can display the information like this:
ViewTable:
practitioner_id :: int
practitioner_name :: nvarchar
insurance_1 :: bit
insurance_2 :: bit
.....
insurance_100 :: bit
In other words, the columns in the view are the ID and name of the practitioner, and every insurance that exists in Insurances (with the insurance name as the column name (there is an enforced condition that insurance names are unique)). The cells in the insurance columns will indicate if that practitioner supports that insurance. Or better yet, is it possible to use an excel-style pivot table on a DataSet in a VB.NET form?

Please see bottom edit for where I am currently at I have created a pivot table that works fine when the pivot cache is defined as:
Dim ptCache As Excel.PivotCache = mainHighway.PivotCaches.Add(SourceType:=Excel.XlPivotTableSourceType.xlDatabase, SourceData:=mainHighwayData.Range("a1:v7500"))
My problem is that the number of rows changes from day to day, so I figure out the number of rows in the worksheet and then use that in my pivot cache:
Dim highlRow As Integer
highlRow = mainHighwayData.Cells.SpecialCells(XlCellType.xlCellTypeLastCell).Row
Dim ptCache As Excel.PivotCache =
[code].....
This returns the proper number for the last row, but once again throws the same type mismatch error.
Edit: I found out another bit of information, but I am not sure what to do with it. The pivot table works fine if the values in it are <= 65536, but the second I increase the range to 65537 I get the type mismatch that has been haunting me. This is true for all numbers >= 65537. I know that 65535 or there abouts used to be the last row in excel, but that is no longer the case. Also when I create the pivot table manually in excel I have no trouble and it has all of the data. I am using int or long, so it should not be an overflow or anything. Anyone have any thoughts on why VB.NET will not let me make a pivot table based on data with more than 65537 rows?

What is the above equivalent for a windows application?
m planning to make it as such:1. BLL and DAL are on the same box.2. Only PL is installed on client machines.Simple enough. Right now am planning to go web service as I have no idea how to do this with windows forms. So in a nutshell, my question would be how to connect the PL to the BL and how to do this during the development stage. I was planning on deploying the BL as a webservice then during development, the PL sets a reference to it to get the data.Data will basically be datasets, datatables etc. Might also have a need to do some file transfer.
