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 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:
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 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 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?
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:
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.
I have a Microsoft Office Pivot Table 11.0 in my form in Ms Visual Basic .NET 2005. I've already succeed displaying the report. But what I want to do is customizing it. I want to be able to change the dimension or the field of the dimension by clicking a checkbox or something like that. How to do that programmatically ?
I'm on the process of linking my AS2005 cube to VB 2005 using ms pivot table 11.0. However, instead of doing an early binding, I want to code my datasource connection.
I am a new user of Visual Studio 2005. I am looking to create a pivot table for data in my excel spreadsheet using Visual (Basic) Studio 2005. I am getting an error in the following two lines of code, which work fine when I use Visual Basic 6.0 but not with Visual basic that comes with VS 2005. Can anyone let me know why the error occurs and what the correction should be?
I have a table of data in Excel 2003 of which I have managed to automate through a VB.NET application to create a Pivot Table. (Will be doing hundreds of these and therefore cannot just run a macro each time...will put the code in a for loop for each spreadsheet in a directory) My problem is that I am trying to create a pivot chart based on the pivot table.
Some code below....I need to create a pivot chart based on the pivot table below!
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?
I am getting error "Exception from HRESULT: 0x800A03EC" near (******). can anyone please help me out. i have seen [URL] this blog also but there are also errors in that. can anyone please provide me the correct code for creating a pivot table. The code is,
This should be very simple but I'm very new to Visual Studio so I can't get it to work. I want to take data from an excel (2003) file and turn it into a bunch of charts that would be viewable on a webpage that I'm trying to build in Visual Studio .Net 2005 professional.
I can't seem to use an excel file as my data source, here are the steps that I've followed:
1) created a new asp.net project
2) dragged a report viewer from the toolbox and it asks me to choose a report or "Design New Report."
3) Clicked Design New Report, and it opened up a new blank report.
4) Clicked "Add New Data Source" and got the Table Adapter Configuration Wizard.
5) Clicked new connection and it brought up the Add connection table.
6) Clicked "change" under data source and I chose Microsoft ODBC Data Source (not sure if that's right.)
7) Under "Data source specification" I chose "Excel Files"
- The first time I did this it brought up a window for me to choose an excel file so I did. Something along the way failed out but it stilled saved "ConnectionString1" as a connection to that first excel file. Now every time after I choose "Excel Files" and click "OK" the add connection window disappears and it goes back to the Table Adapter Configuration Wizard with the "ConnectionString1" as the connection string. It won't let me specify any different excel file. So I did 1-6 again and picked up at 7B
7B) Instead of using "Use user or system data source name:" I chose "Use connection string:" and clicked Build.
8) Picked the "Machine Data Source" tab and chose "Excel Files" and clicked ok
9) The "Select Workbook" window appears so I went to the file I wanted to use as my data source and click OK
10) Back on the Add Connection window I clicked test connection and it succeeded so I clicked ok.
11) It goes back to the Table Adapter Config Wiz window, but the connection string only says "Dsn=Excel Files"
12) clicked Next, then Next again, then clicked on Query Builder. The Add Table window pops up but there is nothing in there for me to choose from.I've tried a million other things, here are a few of the errors that I seem to get a lot.

Does anyone have any thoughts? Is there a reference I need to add or something?
I'm using EPPlus to create Excel reports. Now i'm trying to create a Pivot with a DateTime PageField, so that the user can filter the period he want to see by himself. But although i can filter this for year,month or days in the according data worksheet by default, i don't get it working in the Pivot.
Here is what i have:

I'd like to bind my textbox into two (column)from different table is it possible to do this? I already know how to bind (one-to-one) controls and table.
I have a two forms with about 25 bound controls on each in the same solution. All of the data for both forms is in the same SQL table. I need to filter the data and only get the data appropriate to the called form. I consulted an University VB professor and he would only say "it won't be easy".
I tried removing all of the bindings and rebinding them to the new datasource but there were still some remnants (probably from the navigator) that proved illusive.
Is the only solution to recreate the VB forms and bind them to the new datasource?

I have two comboboxes. The data sorce of combobox1 is a list of string that is fixed.Combobox2's data sorce will be a list of string that depends on the selection of combobox1. This is very similar to a common case as follows: first enter your contry, then depending on your enter, the second combobox will show you the list of universities in the country.

I have inherited an application at work that someone else started creating, right now about 1/2 of it is functional and is in use. My problem is that it is all done in 2.5 ?? and I am trying to step through it all to figure out how it works. I have always created my own binding sources, adapters and data tables.
One of the things I need to do is add a field to the fm_fieldman_master data table. I add the field in the db (SQL Server 2005)table, I come into VS and refresh the datasource, I then add the field to the fm_fieldman_master data table and the Fill,GetDAta() query I go into the designer and create all the attributes for the combo box
