I am working on a class that generates a report in Excel (any version).I need to perform a bit of ad-hoc labelling on a chart, for which I have created a textbox (i.e. Excel drawing object).I've managed to get as far as creating the textbox and setting it's text using Shape.TextFrame.Characters.Text. Ideally, I'd like to set the font characteristics as well, but I can't see how to do this. I can't seem to find much info about this anywhere, so hopefully someone's dealt with this before and can give me a few pointers.

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.

The problem I have is that I have a 3rd party add-in working in excel to convert certain info into a barcode.
When I open excel normally, the add in works without a problem, but when I open it through excel it just doesnt work until I manually go into the add-in option, disable the add-in and the reenable it.

I am working with a project where i am opening up excel worksheets, sending data to them and then printing the worksheet. I have been working specifically with Office 2010 and have everything working exactly how i want it to work. Recently i have been asked to make the same type of thing work for users using older versions of office.
So as a test i took one of the worksheets opened it in 2010 and saved it as a 2003 document. I went into the code switched the .xlsx over to .xls and gave it a shot. It appears that the code opens the correct file. Sends all of the data out to the worksheet and then the program bugs out.

I have an application that opens up Excel, reads some information, then closes Excel. I developed this application using Microsoft Office XP 2007. A few weeks ago, my company upgraded to Microsoft Office 2010. The applications still works fine, but I can not compile in VS 2008 anymore. I get the error message: "Error 3 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'." I have updated my COM reference to Microsoft Office 14.0 Object Library, but the same message appears. [code]Obviously there is a bunch of stuff under this, but this shows where the errors are.I am unable to fix a bug in the program because I can not even compile it without error.

I am currently writing a program in vb.net that will read and write to an exel sheet using OleDbConnection. I can read in from the file fine. When I save to the excel sheet and open it, the changes are there, however, when I close the file it asks me if I want to save, which makes me assume that the changes are not saved even thought they show up.
Below is the code I am using:
Dim conn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & excelPath & ";" & _

The ExcelClass.vb code used to be in a module(Changed it to classes), and I found it online. Unfortunately, I can't find the link .The program is supposed to look through one file (I call it, the donor, cell, or excel throughout the program) and compare the values found in Column C to the values found in column B of another file, called "definitions". If it finds a match, it'll take the abbreviation in definitions and paste it over the value in column B of the donor sheet.The code maybe solid, I think it is, but I can't find out. It crashes with the above error as soon as it comes time to use the getCell function.[code]

I have a vb.net function which uses oledb to create a spreadsheet, then treat it like a database, creating tables and inserting values. The function takes in a filename and a dataset, and returns the filename if it worked. The function works beautifully on my dev machine, but not other PCs. Below is my function, is there anything wrong with the code? EDIT: There are no errors being thrown, the resulting file doesn't contain any data.

We are using .NET2.0 and Office 2003 to develop a desktop application. We met the following problem which may fail the project.We developed some functions in our .NET application and exposed to Excel as an external automation. Then we developed reports template in Excel with these custom functions to generate our report data defined in Excel cells. However, when we tried to refresh the report via .NET to call Excel in background mode, we met the problem that the defined automation is either not loaded or not working after loading. It is extremely volatile. Then we could not refresh the data as desired to display it in .NET forms.

I'm a VBA programmer and can do Office integration in Office applications.I'm programming in VB in VSTS 2008 and following these steps to create an Excell application at runtime: [URL] but it is not working.The issue I'm having is when I add the reference, the library is not recognized by VBE intellisense and compiler, so: the code doesn't run.When I use late binding technique and declare variables as objects, the code runs OK, but I don't want that way.I tried adding the references in two different ways:
1 - Menu Project / Add Reference / tab COM / Microsoft Excel 11.0 Object Library / OK
2 - Menu Project / VB Properties / References / Add / Microsoft Excel 11.0 Object Library
Both methods didn't work.

I should mention I am developing this in SharpDevelop, so if it's a bug with this software then I'll take this up with them.
So I am having issues with trying to get a right-mouse click to work. I have a grid of 30 buttons and I need to right-click to enable a button and left-click disable. I have surfed all over the internet trying to find the answer and the closest I have come to it is it detecting a left-click, but never right.
Sub Button1Click(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.Click
DataGridView1.CurrentCell = datagridview1.Rows(0).Cells(0)
[Code]......
As you can understand, I am having a lot of frustration with this. It just seems that I can't get it to work. I've scoured the internet looking for a solution without avail.

I'm having an issue with rasing an event. In my application I have a form and within that form I create an instance of a class (clsUsage). Within clsUsage I create an instance of clsUser which does several checks form permissions and other things. What I want is for clsUser to send status updates to clsUsage. ClsUser will be a dll but for now I've got it as a separate project in my solution. The RaiseEvent in clsUser seems to execute but the proc in clsUser that handles the event does not execute. I'm wondering if this is threading issue.

I've updated my settings via:
My.Settings.SomeString = "new text"
then I call
My.Settings.Save()
When I check the .config file, the entry under
<userSettings>
<BE.IS.My.MySettings>
<setting name="SomeString" serializeAs="String">

... the value remained the same, unchanged.1 thing though, my app is started via Sub Main() in module file, instead of "Enable application framework". Does this affect the saving of Settings file?

I have some code written by another developer(no, really). The datagridview has the AllowUserToResizeColumns property set to true, but at runtime the grid will not allow column resizing. I've checked the code to see if the property is being set in code and I can't find anything. Is there some other grid property that, if set to a certain value, will disable column resizing?
