There is a requirement like in a web page having FileUpload control and button. I need to upload excel records to sql database. If the excel file having less than 1000 records then it is executing fine and if the excel file having more than 1000 records then it's giving me the error message like bad request (error code: 400).

View 1 RepliesI am experiencing the following page error when trying to use the FileUpload control on my web page to upload files larger than 3MB or so. The error is as follows:"Problem loading page The connection was reset The connection to the server was reset while the page was loading.
* The site could be temporarily unavailable or too busy. Try again in a few moments.
* If you are unable to load any pages, check your computer's network connection.
* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."I suspect this may be due to a timout issue. If so, how can I increase the timeout period for this control / process? I am coding in VB.NET.
I am having a File Uploader. In that, I am trying to assign the file uploader value to the text box. I did this in java script. But when I tried to hit the update button it leaves me an java script error saying Access is denied.
View 1 RepliesI need some help to figure out how to check if a file already exist in the db. My mind is froze. I am using sqlserver 2005, vb.net and vs 2008, not that matter for this quesiton, but in case if you deem necessary. I have an fileupload control and all I am trying is to check if the uploaded file already exist in my webserver or db. I am saving the file to the file directoy but I have the file name stored in the db. So I want to check the file name in the db for duplication. If it exisist I will not save the details. How do I do this.
Dim conn As New SqlConnection(resumeDatasource.ConnectionString)
If Exists("select EmailAddress,IPAddress,fleName from Resume where fleName =" & " 'strflename'") Then
MsgBox(" file already exisist", MsgBoxStyle.OkOnly)
Exit
Else
MsgBox(" thank you for uploading your file", MsgBoxStyle.OkCancel)
End If
I'm using the FileUpload server control to upload a HTML document previously saved(as webpage; filtered) from MS Word. The charset is windows-1252.The document has smart quotation marks(curly) as well as regular quotes. It also has some blank spaces(apparently) that when looked deeply are characters other than the normal TAB or SPACE.When capturing the file content in a StreamReader, those special characters are translated to question marks. I assume its because the default encoidng is UTF-8 and the file is Unicode.
I went ahead and created the StreamReader using Unicode encoding, then replacing all the unwanted characters with the correct ones(code that I actually found in stackoverflow). This seems to work....just that I cant convert the string back to UTF-8 to display it in a asp:literal.
The code is there, its supposed to work....but the output(ConvertToASCII) is unreadable.Please look below:
protected void btnUpload_Click(object sender, EventArgs e)
{
StreamReader sreader;
[code]...
Also, as I said before, there are some more "transparent" characters that seem to correspond to where the word doc has numbering indentation that I have no idea how to capture their unicode value to replace them....so if you have any tips,
I have a strange thing going on with the .net fileupload control. If I remote desktop to the server that houses the web app and db server, I am able to upload files and store them into a varbinary(max) column.
However, when clients connect to the web server from their desktop, then can do all the things they need to such as browsing web pages, fill out forms that store/save data to the database, etc.
However, when they try to upload a pdf to the sever, the following exception occurs: The web app uses .net 3.5, the db is sql 2005, and code is c#. And insights would be welcomed. Code and Exception below.

View 1 RepliesI'm trying to use an asp:FileUpload Control to allow users to upload files (.doc, .gif, .xls, .jpg) to a server that is outside of our DMZ and not the Web Server. We want to have the ability to look at these files for viruses, structure, etc prior to saving them into another directory that would allow access to outside users. From what I have read about this control is that it will allow for files to be uploaded to the web server. Can this control be used to upload files to a server other than the web server? If it can be done where should I look for this type of functionality or how do I force it to go to https:servernamefolder name (Where server name is not the web server)? Would I have to read the file then write it to the other server?
View 2 RepliesIn continuation to my previous research at this link : Security Risks or concerns with the use of FileUpload control of asp.net - how to Scan files during upload, also how to intimate user if file is virus affected and abort the operation. In addition to above, we have McAfee Antivirus installed on our servers. I heard that there is some APIS for this work for Symantac Antivirus but I am not sure about McAfee antivirus.

View 2 RepliesI'm building a dynamic form using XML and XSLT. Anyway I'm using a custom asp.net control for CKEditor, it's an HTML editor.
When I try to add the controls from the XSLT using Page.ParseControl(<the-string-from-the-xslt-here>), I get a warning saying:
Unknown server tag 'FCKeditor.CKEditor'
And of course, if I remove the control from the XSLT everything is working fine and all the regular asp.net controls like TextBox etc get rendered to the string just fine. Does anyone know what I can do about it?
We have a MOSS 2007 custom web part based on a user control that queries a database cluster. When the connection to the database is made, we regularly experience the error below and have had to create a work-around in the code to retry the connection. We have 3 environments - development, staging and production; the error only occurs in production. The difference in the production environment is it is a farm with 3 WFEs and a SQL cluster, where development and staging are single machine instances. All are MOSS 2007 & SQL Server 2008. We cannot find what is causing this issue and I'm hoping someone else has experienced a similar problem and knows the cause.
This is the error that occurs frequently when the query is executed:
System.Data.SqlClient.SqlException: A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)

More than one method will generate this, but this is typical code, note the retry work-around:
public static DataTable OurMethod(string someParam) {
const string query = "sp_OurStoredProcedure";
var resultsTable = new DataTable();
var connection = new SqlConnection { ConnectionString = OurDatabaseConnection };
var command = new SqlCommand(query, connection) { CommandType = CommandType.StoredProcedure };
var dataAdapter = new SqlDataAdapter(command);
var retry = 5; SqlConnection.ClearPool(connection);
while (retry > 0) { try { command.Parameters.Clear();
command.Parameters.AddWithValue("@someParam", someParam);
connection.Open(); dataAdapter.Fill(resultsTable); retry = -1;
} catch (Exception ex) { retry--; if (retry <= 0) {
LogError("Exception: DataAccess:OurMethod: *RETRIES EXCEEDED* " + ex, "error");
} else { SqlConnection.ClearPool(connection);
LogError("Exception: DataAccess:OurMethod: ATTEMPTS REMAINING " + retry + ". " + ex, "warning");
} } finally { dataAdapter.Dispose(); command.Dispose(); connection.Dispose();
} } return resultsTable; }
