I have to write an application in Visual Basic.Net that will open an excel file, run through the contents an export a test file for processing.
The application works great for me (Windows 7) but when transferred to a WinXP PC gives the following error: HResult 0X800A03EC
I can replicate this error by making the Excel Application visible so it seems like it is an issue where it can't access the file because it is open. Error occurrs when trying open the workbook.
Original Code
Dim excel As Excel.Application
Dim wb As Excel.Workbook

View 8 RepliesSo I need to create a windows form that is able to generate reports by querying a SQL Database or SQL Server. There is data in the databases that will be put into an excel file from whatever columns from a specific table I need. I need it to be a dynamic query that is probably hard coded into the application because I might need to write other queries at some point to generate different reports that need different columns.
What I need is somewhere to start or some code that I can look at because im not very familiar when it comes to vb.net/excel. I need code to get all that data from the database and put it neatly in an excel file and I would like to specify what columns in the excel file all the data goes under.
I am trying to import data from an excel file but the spreadsheet name is causing problem. If I use 'Sheet1' as the name of the spreadsheet from which I want data, then it works fine but I want to change the name of the spreadsheet to the name which has spaces like 'PROJECT SHEET'. Please guide
Dim ExcelFile As String = "C:ProjectFile.xlsx"
Dim myDatabasePath as string = "C:ProjectsDatabase.mdb"

I just came upon this article here which can turn your day to day visual basic app to run on mac os x. Here is the link: http://mac.sillydog.org/dev/visual_studio.php The thing I don't get is that the author doesn't tell us specifically what to download, and where to get all the files. He's a bit vague... Can anyone make this clearer to me?
BTW: I am using VB.NET although the author uses C#. I think it will still work though.

View 1 RepliesI have an project which was written in VB6 and made use of the Spread3.0 component to display multiple large data from database in spreadsheet. My objective is to convert this project into a VB.NET current version which would not use the third party component but can possibly use a freeware that does similar if not all the functionality.
My question is, are there any freeware that is available in .NET for such spreadsheet-like manipulation of data programatically? I have come across dsoFramer but this only allows the display of the data in an IE frame. I would like to jus embed the content into my existing form.
Also this freeware must be able to handle formula and user-editing as well as multiple cell type such as combobox/checkbox etc.
