Combining Worksheets ( In Pivottable Format) In Multiple Workbooks Into 1 Worksheet In A New Workbook Which Will Auto Update?

Dec 23, 2009

I have 2 workbooks( Book1 and Book2) with multiple sheets.I am only interested in one of the worksheets in the workbooks(both the worksheets names are the same).The thing is that the data is in the form of pivot tables, so each time i have to filter according to specific categories, copy and paste into another new workbook.The thing is column headings in both the worksheets are different,BUT BOTH the worksheets data must be combined into 1 single worksheet( row after row).

Meaning in Book1, my columns are in the form of Cost, revenue,margin and in book2, the columns are in the form of Cost,Revenue, Profit Margin %.... That means i must add a profit margin % column in Book1 and a Margin column in Book2 before I combine the data into a single worksheet. Each week, new data gets added into Book1 and Book2, so I wish to automate this by creating a code, so that when the source data changes, my new workbook's data also changes.

Delete All The Worksheets Contained In A Workbook?

Jan 21, 2010

I'm trying to delete all the worksheets contained in a workbook using the code below but I get this error:

"Attempting to call into managed code without transitioning out first. Do not attempt to run managed code inside low-level native extensibility points, such as the vectored exception handler, since doing so can cause corruption and data loss."

For Each obj In xlWorkBook.Worksheets
xlWorkBook.Worksheets(obj.Name).delete()
Next

I tried to do this a different way yesterday and it told me I couldn't have a workbook with no worksheets. Is this written in stone or can it be done?

Setting Loop Counter=number Of Worksheets In Any Workbook?

Jun 18, 2009

I want to write an Excel macro to set print formats in all worksheets in a workbook.  I don't think you can do this by grouping; it appears you have to do it in each individual worksheet.  I want to be able to run a macro in any workbook to loop through all worksheets in the workbook and then select the first worksheet.  

How do you have the macro determine how many worksheets there are and set the loop counter equal to that number?

Merge Multiple Excel Files Into One Excel File And It Works For 3 Source Files But Its Not Working If Workbook With Worksheet Count Is > 3?

Aug 18, 2011

I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.

Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

Error When Creating Excel Worksheets / Access Is Denied

Sep 8, 2011

I'm trying to generate Office 2010 files (xlsx) in a vb.net project (Visual Studio 2010 fw 4.0).On my developing PC it works. Once on the server it generates an error:Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).On the server I tried with dcomcnfg and navigate to DCOM Config and locate Excel. To solve the problem I would have chosen Customize in the Security tab under Launch and Activation Permissions and add the account under which the site is running (our server task user) and assign Local Launch & Local Activation permissions.[code]

.net - Copying Multiple Worksheets Simultaneously To Preserve Chart References?

Apr 22, 2009

I've created a two-worksheet template in Excel - the first sheet is for pretty charts, and the other sheet is for the data that drives those charts. I've written a vb.net 2005 app that can dump in all my data on the second worksheet, and the chart worksheet updates perfectly.I would like to do this report several times over in the same workbook. (So the tabs would read 'Person1 - Chart', 'Person1 - Data', 'Person2 - Chart', 'Person2 - Data', etc.)

My solution was to, for every person this report was going to be run for, copy the chart template, and then copy the data template. The problem is that every chart template that is created points to the original data worksheet. How can I set what worksheet each chart worksheet is pointing at?

Multithreading Errors With Excel Workbook?

I have a .Net program that responds to worksheet updates of an Excel 2003 workbook.  Sometimes when the worksheet is updated and I try to write related data to my forms, I'm getting "Cross-thread operation not valid...." errors.  This confuses me, as I have never done any multi-threading in my program.  Does the mere act of me responding to events of an external excel worksheet mean I am now multithreading?  Is there a way to handle the events without multithreading?

Using VB To Find A String In An Excel WorkBook?

Aug 28, 2010

I am working on an application where I need to locate a range of cells within a worksheet.  Since the actual location of the data will vary for each worksheet, I have come to the conclusion that I can put a string near the range that I am looking for (i.e. the text "*SUMMARY*") and since I will know the location of the data that I am looking for relative to the location of this text string, it should work.

I have made some progress but am having trouble getting the Find method of the range component to work.  My code is below.  This code finds each worksheet and shows me the name but I also need to to find the location of the cell with the string "*SUMMARY*" in it (if it exists).

I have a little problem with a small application that uses an excel workbook, and i don't know what's the best way to handle this.In the past every computers here in the company had the same culture and the same office version/language.Now the company bought some new machines, that came with english version of the office (en-US). Now the program doesn't work, throwing the exception related with the assembly of the office.

I have two solutions to solve this, install the mui in all the computers, or the one that i want, adapt the application to work independent of the culture in the client machine.So how to accomplish this? Set the application culture to the same culture in the computer (i think this will not work, because the excel assembly that i ship with the application isn't the correct one for the client language it's the assembly of my machine language)...

Excel - Open A File In An Active Workbook?

Aug 19, 2010

I have a program that filters data and then outputs it to a tabg delimited file. I then use Excel Interop to open this file in Excel because directly outputting to a worksheet takes too long. So currently I am using this code:

AD.DF.WriteToFile(vbTab)
Dim WB As Workbook = ExcelApp.Workbooks.Open(AD.DF.DatafileInfo.WriteToFileLocation)
ExcelApp.Visible = True

The first line takes the filtered data and outputs to a tab delimited file. The second opens that same file in a new workbook in Excel. And obviously the third makes Excel visible. Here is my problem though: right now when this code is run there are two open workbooks. I already have an active workbook and I would just like to open this file to that workbook.

VS 2010 Open Active Excel Workbook?

Aug 8, 2010

I am finally switching from VB6 to VB Net and am rewriting a technical application that calculates the heat transfer performance of automotive radiators, heater cores, evaporators, condensers, etc.The user can calculate a heat exchanger and save the results to an Excel spreadsheet. After a series of calculations he can then plot curves of performance.

He can also click on a previous calculation in Excel and import it into the VB routine. The user may have a number of workbooks open when he does this.My problem is I need to open the Excel workbook that is the active workbook. I have been able to select the active worksheet but have been forced to specify the index of the workbook. I have not been able to get the workbook I want.. The code I used is the following,

Dim oExcel As Object = GetObject(, "Excel.Application")
Dim oBook As Object = oExcel.Workbooks(1)
Dim oSheet As Object = oBook.activesheet

How do I get the active workbook instead of Workbooks(1) with an index of 1?

VS 2010 Read A Sheet From A Excel Workbook And Pop It Into A Datatable?

MyDataTable.Clear()

My understanding is that if I make changes in the datagridview it is reflected in the datatable.

So now I want to write the updated datatable back to the appropriate worksheet.

I have read about "insert into" or "update" etc but it is very specific columns and rows.

One other thing, when I set the datagridview datasource as the datatable I get about 9 other columns such as TABLE_SCHEMA TABLE_TYPE etc. Any pointers wher thay are coming from and maybe how to get rid ofthem?
