I am using following sub procedure to export data to Excel in Asp.net
But i am getting error when excel exceeds its limit(65536).
How can i convert it to sheet wise when it reaches maximum limit.
Here is code:
Public
Sub ExportToExcel()'#Region "Export Grid to Excel"
dTAll = Session(
dt = dTAll.Copy()

Below is the code for "Upload" button when uploading any file:
if (contenttype != String.Empty) {
if (File.Exists(Server.MapPath("~/Folder/'" + Txt.Text + "'/") + filename)) {
LMsg.Visible = true;
LMsg.ForeColor = Color.Red;
LMsg.Text = "File name '" + filename + "' already exist. Please change the File name to save this file";
[Code] ....
File upload control allows maximum file size is 4MB. If file size increase to 4MB it shows error page like "the page can not displayed".
I want to increase the size of uploaded files to max 10 MB not more than that. If file size increase to 10MB, it should show message.
I have developed an application using Winforms that connects to the Database using WCF services. All the services are working fine except those that return huge amount of data from the database. I did increase the size of the maxReceivedMessageSize and maxBufferPoolSize to 9223372036854775807 in the Config file of the client which I believe is the largest but I still get the error message "The maximum message size quota for incoming messages (65536) has been exceeded". I am using visual studio 2010 with VB.Net programming language on the client side and C sharp on the server.
I also goggled but the nearest solution I got was to increase the maxReceivedMessageSize which I did but in vain. Below is the detail of the error: "The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.

I have set Private Memory limit of 200mb in IIS 7 for an application pool. The Private Working Set memory(Task Manager) for the application is always below 125mb but the number of page faults have increased a lot and application cache is getting cleared frequently after setting the limit.
I haven't set any limit on Virtual Memory.why the cache is getting cleared even when the Private memory used is below the allocated memory?
I'm trying to do something simple but all the solutions I have read on the net do not work. I have restricted the file size limit to my uploads to 10MB in the web.config file. Now I want to show an error once a user attempts to submit a file larger than 10MB.All I get is a page cannot be displayed if the file size is too big. I have tried the following:

View 1 Repliesthe maximum number of files in a folder, I noticed that DirectoryInfo.GetFiles().Length is returning a System.In32, but the Maximum value of a Int32 is 2.147.483.647 (Int32.MaxValue) while on NTFS (an many other filesystems) the maximum number of files can go far beyond that.
on NTFS it is 4.294.967.295 single files in one folder (probably an Uint32)
Which leads me to the interesting question:
Is it possible to get the number of files in a folder on NTFS with the .NET framework, when the number of files exceeds the Int32.MaxValue, in an elegant and performing manner?
so i am making a file upload. I have, in my web.config:
<httpRuntime executionTimeout="300" maxRequestLength="5120"/>
so the file can't exceed 5MB.
My server side code looks something like:
protected void button_Click(object sender, EventArgs e) {
try
{
if (fupCV.FileName != "") {
DirectoryInfo di = new DirectoryInfo(Server.MapPath("CVs"));
if (!di.Exists)

View 1 RepliesI have a scenario which is there's a gridview with remove button and also a textbox.
Example:
The value of textbox is 2, and rows of gridview is 5 so the rows from 3-5 will be highlighted. And if the user removed the first row, the highlight should be follow. The highlighted row now is 3-4.
The remove button is jquery also.

i am not able to show an alert message when a file is uploaded from a FileUpload control which is more than the size mentioned in web.config file like this in my situation...
"<httpRuntime maxRequestLength="2097151" executionTimeout="3600"/>"
i want to show an alert message when ever user clicks on the upload button if it excceds the size.
I'm trying to increase the execution timeout and file upload limit on my asp.net website but when i try to add
<httpRuntime
executionTimeout="110"
maxRequestLength="4096">
</httpRuntime>
i get the following errors:
Could not find schema information for the element 'httpruntime'.
Could not find schema information for the element 'executionTimeout'.
Could not find schema information for the element 'maxRequestLength'.

View 3 RepliesI'm using ASP.Net with VB (Visual Web Developer 2010) and SQL(Management Studio Express 2008) to create a website that keeps track of employee subscriptions.A date is entered into my database whenever an employee makes a subscription.I need to find a way to send an automatic email to each employee when the current date exceeds the subscription date by one year.
I am unable to use an SQL job as I only have SQL MS express.From other posts I have read it seems the best way to do this is to create a webservice to send emails but I am unsure of how to get the email address for each employee from the database to the web service?Do you guys think a web service is the best way to do this?

I have what would seem like a fairly straightforward task: Export a report (GridView) to a spreadsheet, so that the client (user) can use the data elsewhere. I thought I found a very elegant solution. Here is the code:
Code:
Protected Sub btnWrite2Exell_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnWrite2Exell.Click
Response.Clear()
Response.AddHeader("content-disposition", "attachment; filename=FileName.xls")
Response.Charset = ""

With a little putsing I got it to work, which is good, EXCEPT that it precedes opening the spreadsheet with a warning that looks like this:
