i used the following code and get error at runtime, how I can upload large files into database
code :-
error :- The value of the property 'maxRequestLength' cannot be parsed. The error is: 2097151 is not a valid value for Int32.
I'm using the AJAX ModalPopupExtender control in order to popup a "Login" panel. My problem is that the TargetControlID property happens to be an ASP.Net Menu Control Item. How do I reference that menu item where it's becomes a valid value for the TargetControlID property?
View 3 RepliesI have an application (asp.net 3.5) that uses a fileUpload control. I have the entry in web.config set to:
<httpRuntime executionTimeout="3600" maxRequestLength="2097151/>
If I try a large file upload (around 20M), I get the "Internet Explorer cannot display the webpage" error. This code worked on another server and works locally, but when put on a new web host's server, I am getting this error all of a sudden. Is there any way I can get more information as to the cause of the error? I set my browser to uncheck "Show friendly http error messages", but I don't get more information.
Let's say you set maxRequestLength to the max number (2097151) (units are KB) and use the following code for your OnClick event for your submit button:
int int fileSize = FileUpload1.PostedFile.ContentLength;
if (fileSize < 2000000)//units are bytes
Label1.Text="too big";
else
{
FileUpload1.SaveAs(saveItHerePath);
Label1.Text = "Upload success.";
}
Why when a huge file is attempted does it take a minute to get to the OnClick event on the server? Because if maxRequestLength were set to that value 2000, it would immediately choke if you tried to upload a 500MB file. What is going on here? What are the best practices for using the FileUpload control? Is there a better alternative way of uploading or checking for file size?
I am limiting file size users can upload to the site from Web.config. As explained here, it should throw a ConfigurationErrorsException if size is not accepted. I tried to catch it from the action method or controller for upload requests but no luck. Connection is resetted and I can't get it to show an error page.
I tried catching it in BeginRequest event but no matter what I do the exception is unhandled.
Here's the code:
protected void Application_BeginRequest(Object sender, EventArgs e)
{
HttpContext context = ((HttpApplication)sender).Context;
try
{
if (context.Request.ContentLength > maxRequestLength)
{
[Code].....
But I still get this:
Maximum request length exceeded.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: Maximum request length exceeded.
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Update:
What method raises the exception anyway? If I read the request it raises exception If I don't read it at all, I get "101 Connection Reset" in browser. What can be done here?
I have a file upload control on my page. The maximum request length set is 8 MB (maxRequestLength = 8192). I also have server validation that throws an error if the file is more than 4MB. The reason that its 8MB in the config is the leverage that's given to the user and also that the app can be tested.
If I upload a file that's 9MB, I get thrown an exception "Maximum request length exceeded.", which is fine and as expected.
But when I try to upload a file that's 1GB, it shows me a HTTP 404 - File not found. how can I get it throw me a maxRequestLength exception?
I'm using IIS6.
Code:
<system.web>
<httpRuntime maxRequestLength ="1"/>
Above I have set the maxRequestLength to 1, it means i can upload the file upto 1024 MB.
Suppose I want that the user cannot upload the files greater than 4 MB.
Then 4 MB = .00390 KB
How to get above decimal value in maxRequestLength???
Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.
Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.
[code]....
As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.
I need to set a style property of an element to the value returned from a code-behind property. I have done this in the past, but it now seems everything I try fails. I get an error telling me that the literal is not formed correctly.These are some of the arrangements I have tried:

my web application i use FindControl to retrieve a Control By Name (it returns an System.Web.UI object). The control can be of various type and I don't want to treat them differently: I'd like to set the Text property to a defined string. I hope there's a class that I may use to cast the control and set the Text property.
View 8 RepliesSo what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
Is there any difference between accessing a property that has a backing field
private int _id;
public int Id
{
get { return _id; }
set { _id = value; }
}
versus an auto-property?
public int Id { get; set; }
The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.
I can't see any reason why there should be any difference between the two from outside the class. Is there?
In the Web.Config we have a timeout property. Ex:
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" timeout="2880"/>
</authentication>
When loggin in, we can specify a ticket expiry date. Ex:
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1, id.ToString(), DateTime.Now, expiryDate, true,
securityToken, FormsAuthentication.FormsCookiePath);
Why there's two places where I can set expiration info about forms-authentication? What's the difference between them? What has more relevance?

I am using C# for ASP .NET 2.0. On my web form I have a TextBox that I want to let the end-user type inside of. The rules are as such: They should only be allowed to type numbers and a decimal. No negative numbers allowed. The number has to range from 0.00 to 24.00 - for hours - and can only allow for quarter hours - example: 0.00, 0.25, 0.50, 0.75, 1.00, 1.25, etc. Do I need a custom validator for this? If so, I do I check to see that the number is valid?
View 5 RepliesI have a registration page with some validation control. There is also a label that is invisible by default. When I click on a button and the page is valid the data is inserted to the database, the label becomes visible (there is text something like: The data has been inserted) and the textboxes become clear so the user can insert another row to the database. Now when I click on the button again and the page is not valid, I get some message kind of insert the name but the label with the text The data has been inserted stay visible. How can I hide the label when the page is not valid?
