An Excel Workbook's Sheet Tabs Be Sorted Within The Workbook?

Jan 6, 2011

In building an Excel workbook with VB.Net, is it possible to sort all the worksheet tabs into a particular order? I'm building a workbook with individual sheets named by drive letter, i.e., "C Drive", "D Drive", etc.

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

Oct 14, 2010

I have managed to read a sheet from a excel workbook and pop it into a datatable.

Public Function GetSheet(ByVal SheetName As String) As DataTable
Try
MyDataTable.Clear()

[Code]....

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?

Why Is The Message Box Behind The Excel Workbook?

May 16, 2010

In the following code why does the message box display behind the workbook,instead of on top of it? It does this related to the line, app.Visible = True.  if this line is commented out the message box appears in front, but there is no workbook visible. I've used the message box in other places without a problem. Is there something fundamental here that I'm missiing?

I have set the identity impersonate to true in web config. This should be mostly an access rights issue.I have even provided access rights for the "everyone " user in the excel file and as well for the interop component. Please post ur valuable comments.

Declaring Excel Workbook In VS/VB 2010?

Mar 25, 2011

My question centers upon the two approaches, (1) and (2), shown below, to declaring Excel workbooks in .Net.The two approaches interact differently with the lines "wkbk10 = app.wkbk10.open()" and later with

Range references to this workbook,like "rng1Stocks = CType(wkbk10.Sheets(1), Excel.Worksheet).Range("H5:H30")".

Multithreading Errors With Excel Workbook?

Aug 26, 2009

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).

Imports Microsoft.Office.Interop.Excel
Public Class Form1
Dim oExcelApp As New Microsoft.Office.Interop.Excel.Application

VS 2010 Program With Excel Workbook?

Feb 21, 2011

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)... One copy for each language, once again it's not possible

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?

Can't Display Created Run-time Exception Handler In Front Of Excel Workbook

Mar 24, 2011

In the following code I open several Excel workbooks from within the VS 2010 .IDE. I want to Try the open workbook code, then Catch exceptions using a dialogbox as a form created programmatically at run-time. The exception handler works, but the dialog box does not display in front of the workbook. So, the user can't respond to the modal form. If at that point the Excel workbook is shrunk manually to expose the dialogBox which is then dismissed, Excel pops up a "Save Changes?" alert and the VB code does not resume the Sub at the Me.Focus() line

When the workbook Is open Excel is the active application. I think this is why the dialog box is not in front, and I don't know how to solve the problem programmatically.[code]...
