I have a simple webpage which uses the FileUpload control. I am trying to select a file from the local pc and save it to the web server which is a remote server on the company network. I have a shared folder on the web server with the appropriate permissions. The folder authentication is using a predefined user name and password.
I have tried My.Computer.Network.UploadFile and System.Net.WebRequestMethods.File.UploadFile. For both methods I am getting the following error:
System.IO.FileNotFoundException: Could not find file 'C:empfilename.xls'

i have an aspx page which has a fileuploader and a button
initially i have to browse the file and after browsing the file i have to check the extension if the extension is xsl or xslx then only i have to enable the submit button
once the submit button is enabled i have to insert this data into the table
and i have to display the number of succesfully inserted rows and no of unsuccessfull insertions .
success and failure is dependent on the mismatch of the datatype between the excel sheet and the database column
i am coding in c# but am unable to upload.

Could someone please tell me/link me to how I could create a method similar to those posted below: [URL] (I am providing the links as I'm not sure how to articulate this question without them!) I'm using C# ASP.NET. IIS 6. I have an existing web server with other public API methods. I do not want the iPhone user to have to open a web browser, and post to an aspx page. I want the iPhone developer to be able to call my method, and have one of the parameters be a handle to the file which gets POSTed.

Server Error in '/' Application. Access to the path 'c:InetpubEnewsAttFilesemploy-e-header2.jpg' is denied. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UnauthorizedAccessException: Access to the path 'c:InetpubEnewsAttFilesemploy-e-header2.jpg' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

I am trying to upload an excel file and my code reads the data of excel one by one. Unfortunately as we all know that excel doesn't restrict the data type for each cells, so there is a chance and possibility that my code can catch the exceptions.
How can I do this?
Code:
try
{
// do the statement
}
catch
{
// throw the exception, log it and then proceed to the next, don't stop.
// then prompt the users of all exceptions encountered.
}
I need to process more than 1,000 rows of data from excel. I don't want every time there is an exceptions the uploading process stops and fixed the problem then re-upload the data again. I want to consolidate first all the data with issues or exceptions then deal with it later after the uploading process done.

We are deveopingawebiste in asp.net. There are tempelates of each aspx page made in the form of excel sheet. Upon completion of the online calculation, the user is to be allowed to export the results to excel and save them. There would be obviously no formulae in such sheet
I do not want to install Excel on theserver and instead want to utilize the Excel installed on the user's computer for this purpose as every user's computer is expected to have Excel installed. Is this possible to do? How to do this?
I am not an expert in this. let me know if you would need any more information or clarification.

I've an application built on asp.net 2.0. There is an option for user to upload excel file. Once the file has been uploaded the data in the file is validated against some business rules. Rows that successfully validates are inserted into database as soon as it is validated.
I use ado.net to connect to excel file. And use data reader to iterate over all the records. Normally the number of records range from 5,000 to 20,000. This process takes good 8 to 10 minutes. I want to optimize this process because to my understanding it takes too long. Currently I am looking at OPENROWSET, OpenDataSource which so far is unsuccessful. Valiation that takes place on every row is very simple. I only checks for maximum length. So validation itself is not an issue.
