VS 2010 - Reading Excel Data Into Dataset Loses Data

Apr 22, 2014

I have a client that provides a .xls file on their site that we have no control over that we download the file and then read it to update inventory. The first column is the SKU and in cell A2 it has the value 1028. This outputs fine but when I get to A8 the value is '1051-LV' and in my output it is blank. I am thinking in my dataset it reads A2 value and that becomes the type for the remainder of the rows. But what if that is wrong? How do I fix so it doesn't set the datetype to say int when it could be a string type?

Below is my code and works but the output of certain rows sku values are blank and are not like that in the excel file.

Code:
Protected Sub btnGetExcelFile_Click(sender As Object, e As System.EventArgs) Handles btnGetExcelFile.Click
litOutput.Text = ""
Dim ws As New WebPost
ws.URL = "http://www.domain.com/dropship/feed.xls"
'downloads excel file based on url
Dim bExcel() As Byte = ws.RequestBinaryData("", True)

[Code] ....

How To Approach A Sharepoint 2010 Development Project Coming From WebForms And MVC

Jan 20, 2011

I have a good amount of knowledge in the ASP.NET Webforms and MVC worlds. Shortly I will be tasked with implementing custom web applications with Sharepoint. I have great flexibility with this project (i.e - I can use custom web apps outside of Sharepoint if that's possible) but like most projects the most limiting factor I have to deal with is time.

Here are some questions that come to mind:

Can I easily integrate a custom MVC project into Sharepoint 2010? What are the pros and cons if I can? Same as #1 only with Webforms. If #1 and #2 are not viable solutions, can I easily create custom web applications within the Sharepoint world? What will the learning curve be with my background? I understand developers can now use Windows 7 to deliver Sharepoint 2010 solutions. It looks like I can use a trial of Microsoft Sharepoint Foundations 2010. If that's correct, are there any development differences or gotchas I need to be aware of before digging into the Foundation version? I don't want to get up to speed on Foundation and then find out that the Server edition (the version that will be deployed) is vastly different.

Visual Studio 2010, WebForms Routing Not Working In IDE Debug Mode - Getting 404

Oct 26, 2010

I am using Visual Studio 2010 and ASP.NET 4.0 to build a WebForms project that uses the new routing features in System.Web.Routing. When I build my solution and run it from within VS.NET's debugging environment only routes with RouteUrl's that include a ".aspx" extension are being properly routed to the PhysicalFile. It appears requests made to other URLs are not being "detected" by the routing engine for processing. In the case below, "Scenario1" shows a 404 and "Scenario2" works properly.

Here is the relevant code in my global.asax:

VS 2010 File (Excel) Uploading And Processing

Sep 27, 2011

I come from MVC side, where these things make more sense (of course just because I know a bit about it) and my webforms are still sucky sucky.

I got a page where I want the user to upload a file (Excel).

Not too worried about the upload timing out, but after uploading this file will be processed (time & attendance data to be written to the database)

So what I'd like to happen is everything happen asynchronously with the page being updated as the file are being processed.

Also, I'm not sure.. won't I need excel on the server to have my code read the excel file?

VS 2010 Create Excel From IList For Download

Aug 31, 2011

User's need to "download" an excel sheet with data.

However this sheet need to be created on the fly (user's can check of which data they want exported).

From the user's point of view, it will just be a link "Download Now".

From coding point of view I will have an IList<MyClass> where MyClass say got members like EntryId, FirstName, LastName etc.

I do not want all fields to be dropped into the sheet (so I will need control over that in my code)

This sounds like what I'm after (since I'll always only have one sheet)

Create an HTML document and save it with a .xls extension - Excel will open it and treat it like a native Excel file. This method is very simple and, of course, free - however, it won't allow you to have more than one worksheet in the Excel workbook...

.net - Update Subtotals In Excel Files?

Jan 6, 2010

I using the OpenXML library to take a datatable and paste it into a pre formatted excel file. This works fine.

The problem I have is there is a subtotal row at the top of the pre-formatted excel file, that is set to subtotal each column of this data (so there is a subtotal at the top of each column). When I open the excel file after it has been created, these values are all set to 0, they have not updated when the datatable was inserted. If you highlight one of these subtotal cells and then press enter, it updates and shows the right value.

What is the easiest way to get these values to update and show the correct value as soon as the user opens the downloaded spreadsheet?

Code for creating the spreadsheet:

MemoryStream memoryStream = SpreadsheetReader.StreamFromFile(TemplateDirectory + @"" + "exceltTemplate.xlsx");
doc = SpreadsheetDocument.Open(memoryStream, true);
worksheetPart = SpreadsheetReader.GetWorksheetPartByName(doc, currentSheetName);
writer = new WorksheetWriter(doc, worksheetPart);
cellName = "A8";
writer.PasteDataTable(reports.Tables[0], cellName);
SpreadsheetWriter.Save(doc);

Architecture :: Consuming Excel Files For WF 4.0?

Dec 6, 2010

Here's what I want to do, however I'm not sure of the best place for Excel. Excel files are sent via e-mail from various sources, from each source, they are sent in different versions of Excel and different information layouts, though from each source they are consistent.

Overview.

I want to give the user a front end to enable them to place the excel files into a drop zone and specify which files have come from which source. I then want to pass the file names and source origin to a workflow service. Based on this info the workflow service will then take 1..n workflow routes based on the source with the ultimate aim that data will be placed into an SQLServer 2005 DB or if the Excel lines cannot be processed, then output for the user to see with a reason. Because this is quite a complex task, I'm taking each source in turn.

Initial Problem.

My first set of Excel files come in 4 seperate files. I need to first merge the data in the Excel sheets to make 1 File for Processing. Some of the rows in the spreadsheets can be merged into a single line under certain conditions which will make the business logic much easier further on. So, first off After the user has dropped the Excel files into the drop zone I need to open the spreadsheets and merge them. I then need to feed each line to a 'rules' engine to determine the data and business logic that needs to be processed before updating the DB. So I thought I'd use a Workflow service for this since there will be no reason not to work on multiple sources at the same time as I progress through the development of the program. The problem I have is that unless I download the CP1 for workflow I cannot use this directly (so it appears) for working with Excel. So I was looking at using possibly WCF as the 'feed' to the workflow service, but can I use WCF to do the possible long running process of merging the Excel spreadsheets before pasing a row at a time down to the workflow service?
