Automatic Download Of A Web Resource From A Spreadsheet?
Jan 11, 2011
I have a datasource of an excel spreadsheet provided by a customer. The data is biographic information about clients. The last row contains a web link to view an image of the subject. I have open access to download the spreadsheet and can click each image to view the full jpg in IE.
What would be the best method to loop through the image link to deposit the image into a central file location? The datasource contains 50K subjects and is updated monthly, this is why a manual process is out of the question.

I've a gridview which I am rendering to a html text writer and allowing clients to download as an excel spreadsheet using Response.Write. I'm using AJAX in my website now and suddenly it stopped working. This is the code I'm using
public static void Convert(DataSet ds, HttpResponse response)
{
try
{
//1. declare filename to export
string filename = "export";
//2. clear response object
response.Clear();
response.Charset = "";
//3. set response mime type to excel
response.ContentType = "application/vnd.ms-excel";
//4. prompt user to download the file
response.AppendHeader("content-disposition", "attachment; filename=" + filename + ".xls");
//5. create a string writer
StringWriter stringWrite = new StringWriter();
//6. create html writer which uses the string writer
HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
//7. instantiate a gridview
GridView gv = new GridView();
//8. set gridview datasource to the dataset
gv.DataSource = ds.Tables[0];
//9. bind gridview
gv.DataBind();
//10. tell the gridview to render itself into htmltextwriter
gv.RenderControl(htmlWrite);
//11. output html
response.Write(stringWrite.ToString());
//12. end response
response.End();
}
catch (Exception ex)
{
string str = ex.Message;
}
}
I've found that Response.Write doesn't work with AJAX. Are there any alternatives to this?

Currently user downloads a (.HTML) file upon Open/Save prompt.
Trying to eliminate user manually saving every file.URL is not a webservice. Similiar to downloading EACH INBOX item (of my personal hotmail) into a induvidual File. without clicking open/save/download.
There is not possibilty of webservice here.

I will be setting the current thread's culture at the beginning of the request lifecycle.
Does it make sense if I create my own resource.xml to store things like strings/labels/messages that will be used in the web application?
or are their drawbacks and its better if I just use the Global resources .resx files that are 'built-in' ?

In our web application we need to keep various company's settings. For eg "DiamondProdRefIDCaption","Shippingpickup","ZipCodeCaption","DefaultCountry","AllowToEditInvoice", etcThese settings are different for various companies and are placed in web.config as key-value pair.Initially, we have tried do simplify this process by adding a company_settings table in the DB so as to allow us to add companies on the fly. However, this method makes it very difficult to add a new setting
<%$Resources:DiamondProdRefIDCaption%>

I have a class library and was to add a resource file to it to support both English and Spanish. Any tips as how I can do this? The language will be dictated by the user visiting the site. Would like to have to only load each resource file once and cache or set in static variable and avoid any overheads.

Possible Duplicate: Create Excel (.XLS and .XLSX) file from C#
I have some code that generates a zip file that contains multiple CSV files and streams it back to the user (no file is saved on the server). However, I want to create an excel workbook instead (can be traditional xls or Office Open XML xlsx format) with each CSV 'file' being a spreadsheet.
How can I do this, without resorting to Office Automation on the server or a commercial 3rd party component?

I have a form that allows a user to import a spreadsheet. This spreadsheet is generally static when it comes to column headers, but now the users want to be able to include an optional column (called Notes). My code crashes when I try to read the column from the spreadsheet if it doesn't exist.

I'm exporting an ASP.NET gridview to Excel using the following function. The formatting is working really well, except I need to freeze the header row in Excel on the export. I'm really trying to avoid using a 3rd party Excel plugin for this, but unless there's some archaic excel markup in my AddExcelStyling function.

I'm trying to upload an excel spreadsheet using the FileUpload control, read the excel sheet using OleDb connection, and save the strings onto a sql server database.Then, I'm trying to read each string in another method.My web app is currently hosted on the network on my local box, and using savePath= @"C:desktop" like I had it previously wasn't working, so I figured using a sql server database would work for being able to save the file and open it again... but I'm getting confused on how to do so, so i tried using my old savePath but it's not working anymore. So... I'm really at a lost on what to do and how to fix it.

How to do something like this without actually downloading the spreadsheet to the local machine? Any tools or what not out in the world for doing something like this? Does sharepoint allow for .xlsx editing in a page?
Anything short of writing all the inputs and mapping them with backend code?

On an .aspx page in a web site I need to retrieve some data from a sql server database and, instead of displaying it in a Gridview, I need to put the data in a spreadsheet and present the user with a Save As dialog.
I'd prefer to do it without using the Office / Excel / Interop com object - so, from what I've read so far, I can do this by returning XML data from SQL Server?
Normally I get data from SQL Server and populate a dataset or datareader with it - and then use this as the Datasource of a GridView.
If I run this in SQL Server ...
Code:
SELECT UserID, UserName FROM tblUsers FOR XML Auto, Root('Users')
It produces this ...
Code:
<Users>
<tblUsers UserID="1" UserName="Steve" />
<tblUsers UserID="2" UserName="Andrea" />
<tblUsers UserID="3" UserName="Zebedee" />
</Users>
So, first question - how do I get the data from SQL Server into my .aspx page? (All data access is done with stored procedures - so, from my data access class normally I create, for example, a SQLDataReader and populate it by calling a stored procedure. What object would I populate with the results of a stored procedure that contains a select statement with 'FOR XML Auto'
Then, assuming I get the XML into the .aspx page - how do I get it into a spreadsheet so that there are two columns called UserID and UserName and 3 rows with 1, 2 and 3 in the first cell and Steve, Andrea and Zebedee in teh second cell?

My company has new customers in Brazil and we realized that our excel reports are not working when our Brazilian customers tried to open the reports in their Brazilian versions of excel.
For excel output we use spreadsheet gear in our vb.net web application. Our excel worksheets are fairly simple. Mostly outputted text/numbers/dates, a couple of formulas (sum, if) and formatting on the currency and dates.
I've tried several methods to get my excel reports to work: First I left the excel workbook in the "en-US" culture and tried simply chaging the number format for Brazil to:
_-[$R$-416] * #.##0,00_-;-[$R$-416] * #.##0,00_-;_-[$R$-416] * "-"??_-;_-@_-
And this formatted the regular cells but the formulas still failed to show a value. Instead they showed a 0 value.
Next I tried changing the workbook to the "pt-BR" culture and that also forced me to translate the formula names (Sum -> Soma, If -> Se) but they still wouldn't should a value and instead showed a #Name/#Nome error. Interestingly enough the formulas would work if I edited the cell and hit enter. The formula wouldn't change but it would some how fix that cell.
I need to be able to out excel reports that can format dates/currencies and apply simple formulas (IF, Sum) for other excel cultures.

Here is my subroutine:

On clicking the ExcelButton I get the error message:
Control 'GV2' of type 'GridView' must be placed inside a form tag with runat=server.
The control GV2 is in fact inside:

I would like to be able to copy one row and five columns from an Excel spreadsheet to a table like structure on a ASP.NET web form. The idea is keeping the data in the exact row and column from Excel to the table like control on the ASP.NET web-form. Then I want to be able to save to the contents of the ASP.NET control to a database by a buttoon command click. What ASP.NET control would allow me to do this? Gridviews and datagrids don't seem to allow me to do this.

I want to show information from an excel spreadsheet in a web page. The xls will have maybe 5 columns, and as many rows as needed. The columns will be 'Name', 'Created Date', 'Expired Date', 'Owner', and maybe down the road maybe more.
What I would like is for the C# to nightly read the xls, and display the information in a table on the website.
If there is a PDF available for download I am going to link that as well.

I am generating, using a ASP routine, Visual Basic, a HTML table in a file to be read by MS Excel.
After Excel reads the file, some of the numbers (in some cells) are shown as "text", not numbers: they cannot be operated upon, like decimal numbers. (added, subtracted...)
If I click in a "number" stored as "text" cell, I can "edit" the cell and remove an invisible "apostrofe" to the left of the number; after that, the "text" becomes "number" again.
Seems like Excel is inserting a non-visible character before the number, so that it is stored as "text"
It happens to some lines and not to others...
