I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data.
I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db. My question is what can anyone give me code to open an excel file, know what line the data starts on in the file, and import the data into a datable object?
well I am trying to export sql data that has 80,000 records more than 65,000 rows which excel has.i do I export that much data in one trial without error.is it posible with bcp utility?
I tried DTS but did not work what option shall i use to define range in excel file to export data ?
I've been searching for various posts on Excel and ASP.Net, and wanted to try and figure out if what I'm attempting has any chance of working. I have a special Excel workbook with a worksheet that has a bunch of calculations and such for various fields that creates an order for his crew. My client uses this Excel worksheet for everything. He's asking me to be able to see online orders (which I have), click a link and have the worksheet be passed down to the client all populated and formatted exactly as is (just adding/editing data).
Is this even possible? I'd have to load this specific .xls file, then open it on the server, save data to various cells, and then do a Save As and then binarystream it down to the client. I'm quite certain there is no version of Excel loaded on the server. So I'm perplexed as to how to accomplish this. Has anyone encountered this situation before and been able to accomplish what's being asked?

I working on this function that takes multiple excel files (each containing 1 worksheet) and basically stitching them together in a new worksheet. My method works fine but I get random empty columns in my new "master" worksheet. I did some checking and the usedRange function takes the data from the excel sheets and adds in empty cells. I was wondering if anyone had a way of either -
1) stopping usedrange from adding empty cells or
2) Taking out empty columns from my "Master" worksheet.

View 1 RepliesI am trying to export crystal report to pdf in asp.net, though the code is working well on localhost but on server I get error
HTTP Error 500.23 - Internal Server ErrorAn ASP.Net setting detected that does not apply in Integrated managed pipeline mode.
The crystal report is showing abnormal behaviors.I am using a CrystalReportViewer on which i have set the CrystalReportSource1 using the viewer Tasks.
The code on page load is :-
cn.Open();
DataSet ds = new DataSet();
string sql = "select * from Test";
OleDbDataAdapter da = new OleDbDataAdapter(sql, cn);
da.Fill(ds);
[Code].....
During the troubleshooting i encountered another unusual issue, where i tried a new crystal report with just simple report. That simple crystal report is not showing data & the toolbar images are not rendered. I googled on this but didn't found conclusive thing.
Is there a way to force the MVC automatically generated code to follow the conventions you have set in your preferences? For example, I keep all curly braces on the same lines as their declaring class, method, etc, but when generating a controller, it completely disregards my settings. Is there a setting someplace to force the same code generation as other parts of project?

I've a requirement to be able to generate PDF's within our (ASP.net) application. We need to meet the following requirements:
The text will be largely dynamic and must be added programatically. we'd like to base these generated documents off PDF templates provided by our designers. Some of the sections/pages may or may not be visible depending on certain conditions - we'd like the content to 'flow' upwards to fill the space when something is removed. Some of the pages may need to repeat, depending on certain conditions.Some of the PDF templates will be out of our control (we're populating application forms supplied by third parties), so being able to read in a blank PDF and populate it would be good.
I've looked at iTextSharp and it seems to do most of these things (i.e. I can take a PDF, edit it to include form fields where we need to fill data and then use iTextSharp to read that in as a template and populate the data), however, I'm not sure how then to go about potentially hiding whole sections and/or repeating pages.
I am trying to use the code available here to generate thumbnail images of url's that are returned as part of a search function in my website. Everything works fine when I am running through the development server in Visual Studio 2010, but when I push the code out to the server (Windows Server 2008 64bit w/ IIS 7 running in Integrated Mode) the code never returns a thumbnail. Is there something I need to do to get this working in IIS 7?
