VS 2010 Working With Excel Files?
Sep 14, 2011
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'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 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.

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 created a program that processes files on a nightly bases for the company I work for. These files are used on a daily basis and very often a file is left open by a user and it causes my program to error out and not finish running. My program needs delete access to these files.
I need 1 of 2 solutions.
1. I need somehow add a check to see if a file is in use and if it is just skip it.
2. I need to make my program automatically force close the files on the users. (note that these are shared by one computer, I can put the program on the computer that the files reside so that it has access to close them out.)
how to add a check for if a file is in use or not?

I am working on saving excel objects to a directory of my choosing. I am able to use a folder browser dialog to select the save location and the saveas method within the excel interop and i am able to create a file in the folder i select with the name i choose. The issue is that when i later go to open that file it is blank. no workbooks no worksheets etc . Just a seemingly blank file in the proper location with the proper name.
It should be noted that if i single click on the report icon to open it the microsoft browser window does show a tiny preview of what seems like the correct report.
eapp.Worksheets(1).SaveAs(FileName:=patient_frm.savefolder & "Lateral Postural Analysis")

I accidentally submitted it before realizing that I probably should have selected the "Visual Basic General" forum. I am attempting to retrieve file properties of all files in a particular folder. I have used objFolder.GetDetailsOf... to retrieve the desired information of Excel workbooks saved in Excel 2003 format, but I cannot retrieve the information from files savied in Excel 2010 format.

Initially my app worked with excel fine, now it causes my computer to reboot only after Excel has been opened (two or more times). I have opened and closed Excel files 20+ times without running thru either of my apps (they all uses identical code for excel) and it has never caused a reboot or a crash.
run either of my apps and have the app control excel has become a crap shoot, it will reboot my computer. Adding to that I then have to do a manual shutdown because the reboot process after is unstable. (System doesn't respond properly). My code in this app is small, should make for a good example. I can provide the entire project to anyone who would volunteer to test it. (First I need to know how to send the project).

I am trying to import a bunch of excel 2003 files all with A:H columns and they are under the same headings etc. into a table in access 2003 database. This is a module in access im making. Im using a file search to look for every file that begins with Format (which they all do ) to get at all the files in the folder path. is there a more efficient way to do this? somehow select all files in a folder? and import each to the same table in access? The DoCmd.TransferSpreadsheet seeems to take each file path individually so I'm not sure how to get each file name in the folder to import it.
I have this at the moment:
Sub Import()
Dim db As Database
Set db = CurrentDb

I have inherited a rather large project consisting of an application written in VB6 and several DLL's and ActiveX controls written in VB6, VB.NET 1.1 and VB.NET 2. I want to change one of the settings for one of the DLL's written in VB.NET 2 that is in its application.dll.config file, but it seems to be having no effect.My main VB6 application (I will call it Alpha) has a configuration file (Alpha.exe.cnfig) which contains settings used by my VB.NET 1.1 DLL (which I will call Bravo). After calling Bravo, Alpha calls Charlie (my VB.NET 2 DLL). However, even though I have changed the application settings in Charlie.dll.config in the subdirectory where the DLL lives, it has no effect. I have tried putting Charlie's settings in Alpha's config file but this causes Bravo to fail with an automation error (which I think is because the format of the config files changed from .NET 1.1 and .NET 2).[code]If I try putting the applicationSettings section under directly beneath the appSettings section (i.e. as another child element of the configuration element) in Alpha.exe.config then Bravo.dll fails.

I need to keep the original Ratio of the Width to Height of an image file within a picturebox, basically I will have to adjuest either the width or the Hidth of it. Does anyone have a suggestion on how I do this? I was thinking I would have to get the Width and Height attributes of the Picture file with an integer and use a little bit of math to determine the approprate size of the picturebox object.

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;" & _

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 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.

I am trying to change the file names of all the files in a directory based on content of the file. So I am opening the file, reading the content, storing the new file name in a variable and then trying to change the name of the file. This is not working because when I start this loop I am opening the file and viewing it so it won't allow me to change while the file is in use. Should I store the old and new file names in an array and do the renames after the For Next Loop is complete?
