Dim objWorkBook As objExcel.Workbook = CType(objExcel.Workbooks.Add, objExcel.Workbook)
Dim objWorksheet As objExcel.Worksheet = CType(objExcel.Worksheets(1), objExcel.Worksheet)

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'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 am back with new problems relating to TabControl Page. On the TabControl there are 2 Pages which are : PagDisplay - Contail DataGridView (ReadOnly)PagEdit - Contain TextBox controls for editing data from PagDisplayThe System Analyst specification is after editing the data at TabPage2 when the user click on PagDisplay on TabControl it will activate the Function FCheckData to validate all the textbox data on PagEdit. If there are invalid data, Function FCheckData will return FALSE.When FCheckData = false, it should return to TabControl1.PagEdit page but I don't know how to do it. Here are the incomplete coding.
dim bolEdit as boolean = false
Private Sub TabControl1_SelectedIndexChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles TabControl1.SelectedIndexChanged

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.

I have several classes that use a bunch of strings for directories, arguments, etc.
At the moment, they're all just declared globally within the class like so:
VB.NET
Private str1 As String = "path"
Private str2 As String = "path2"
Private str3 As String = "arg"
To me, that looks awful and doesn't seem like the proper way of doing things. So, I was thinking, should I make a property for each string and then use a constructor to initialize them?
Would that make a difference at all? Is that the proper way of doing things?Also, some strings are used in a ton of different places and they're basically just being copied from one class and pasted into another. So, do you think I should do what I suggested above, but with a class whose sole purpose is to house those strings so that the code isn't duplicated a million times everywhere? Would that be the most efficient way of doing things?

Why are static variables set equal to 0 in the declaration when 0 would be the default value of the numeric variable anyway when it's first declared? Not including the "=0" in the static declaration seems to work with no problem.

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 & ";" & _

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.

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.

It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]
If it is deemed that this thread is inappropriately requesting help, I ask that it be locked/deleted quickly as I recognize that this is a large community with many discussions going without need of unwelcome posts.

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.
