Using Excel Style Pivot Table On DataSet In Form

Aug 23, 2011

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?

.net - Turning Off Excel Pivot Table Sub Totals?

May 2, 2012

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, _

Generate A Pivot Table In Excel Using .NET 2008?

Oct 28, 2009

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:

Dim wb As Excel.Workbook
Public Sub ExcelGen()
Dim ex As New Excel.Application

[code]....

The error I'm getting right now is the no object reference set error on the "pCat =" line...

How To Create Pivot Table On Excel Spreadsheet

Jan 7, 2009

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).

Datatable To Pivot Table?

May 21, 2010

I 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.

Excel Dataset - Preview In DataGrid And Save To SQL Table

Mar 25, 2009

I am creating an app to grab data from excel and preview in datagrid. From the datagrid I want to be able to save to a sql table. I have the excel data in a gridview via a dataset. What I am having trouble with is the sql statement. I know how to insert data, but I can't work out how seperate the data in the dataset to pass it into individual Values of the insert statement. Or should it be done another way? NOTE: I is not essential that the excel data be previewed in the gridview if this would make life easier for me.

Here is my code so far:

.net - Pivot Cache Type Mismatch Error Excel

May 2, 2012

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?

Update A Single Table Of A DataSet Using A TableAdapter Without Hard-coding The Table Name?

Nov 13, 2009

I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.

What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:

Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter

What I'd like to do is this, but of course it doesn't work:

strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")

Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!
