Web Forms :: Manipulating Excel Files In Vs2005

Sep 24, 2010

I am having problems in manipulating excel files in vs2005. All I want is to get the excel files(this excel has specific design for reporting and has macros in it), read it, add data for reporting purpose, and make that file send to the client. Now, the problems I encountered and will encounter is:

1. It has password protect, I dont know how to unprotect it. I already use sheet.Unprotect("password here") but no use.

2. Actually I cant read this using Microsoft.Interop method.

3. Call every sheets I want to be updated.

4. Update the cells with data from database(getting database data is easy of course)

5. Optional, protect it again.

6. Send it to client(downloading)

Web Forms :: Manipulating The Format Of A Sitemap Menu Control In A Masterpage

Oct 21, 2010

I'm trying to develop a webpage for a small college who want to keep the format similar to an existing webpage. I've created an ASP.NET master page and included a menu (web.sitemap) to navigate the various pages of the school's site. However, I'm trying to format the menu to match their existing old style html websites.

I need to place a line between the various items of the menu. I've tried border but I need the lines to appear above and below the items (or inbetween) and not on the left and right. I've read that I may have to use CSS to format it the way I want but i can't figure out the code to so.

.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?

Databases :: Read Excel Files Using Oledbreader Row By Row?

Aug 5, 2010

i'm trying to read an excel file and get data on a row by row basis. Since after converting the pdf file into an excel file, the formatting went a bit haywire but if read row by row, i'm still able to retrieve the original data.

As I am unable to generate the excel file using a single worksheet, i have multiple sheets in the excel file. I also need help on reading multiple sheets.

Currently i am onli able to get data via columns but due to the formatting going haywire, i gave up on it.

Databases :: Creating, Opening, Writing To Excel Files?

Aug 5, 2010

I am creating an site where a user uploads an excel file to check if any of the records exist in a database. Then they are returned an excel file with only the records that are NOT in the database.
I was thinking I should do it this way1. User uploads their excel file. The app opens excel file and loads records into a dataset (so far this is working with the code below)2. Using datarow and another function to check if each excel record exists in the database3 If the record does NOT exist, and it is the first record tested, create an excel file called records.xlsx and write the record into the file

4. Check the next record and if it does NOT exist in the database, then check if records.xlsx already exists then open it and write it into it.

[Code]....

Hopefully its clear, sorry if its not, I'm a bit of a novice at this. Is this a good way to do it? Does anyone know of any tutorials that might outline how to open an existing file and write to it?
