Hello,
Check the file length first. You may helped by the following code. (Refrence : using System.IO;)
FileInfo FI = new FileInfo(@"C:\Rate.txt");
Response.Write("File Size : " + FI.Length.ToString());
This code returns the size of the particular file. You may check the file size u want.

Best Of Luck.

Hi dear,
For making upload more than 4MB you just need to alter ur webconfig file, becoz by default webconfig settings allows for 4MB data transmit.
u can find the Code line for same thru google.

hi iam using check boxes in the grid view.now how can i make the user has to select only one check box in the grid view
|
|
|
|

Why don't you use "radiobutton" instead of "checkedbox"? Basically, the checkedbox used for selecting multiple items.

I don't want to say it's impossible.. but if you are using checkedboxes instead of radiobutton for your case, the user might feel confused. That's why I suggested you to use radiobutton.
If you want to get the example, you can check-out the link..
As this article RadioButtons inside a GridView control[^] mentioned, you can use HTML radio button instead of Server-side control if you want the user to select the only one radiobutton..
OR
Adding a GridView Column of Radio Buttons[^]
OR
http://forums.asp.net/p/1050958/1484724.aspx[^]
<br />
protected void rbSelector_CheckedChanged(object sender, System.EventArgs e)<br />
{<br />
foreach (GridViewRow oldrow in GridView1.Rows)<br />
{<br />
((RadioButton)oldrow.FindControl("rbSelector")).Checked = false;<br />
}<br />
<br />
RadioButton rb = (RadioButton)sender;<br />
GridViewRow row = (GridViewRow)rb.NamingContainer;<br />
((RadioButton)row.FindControl("rbSelector")).Checked = true;<br />
}
Hope it helps..

Is there a way for me to create a new thread with ASP.Net using C#?
|
|
|
|

Either spawn a new thread by creating a new instance of the System.Threading.Thread class, or assign work to a thread from the threadpool by calling System.Threading.ThreadPool.QueueUserWorkItem.

The real question is, why do you want to ? I mean, there are limited ways in which that can help in ASP.NET because the class is generated on a postback and is gone when the page is sent back.

I'd recommend buying a book on ASP.NET. Beyond that, I'm not sure what you're asking. You know how to code, but you don't know HTML/ASP.NET ? You've written pages before but somehow think there's more to know when writing the whole site ?

Here is the code I use to post a request to Authorize and get a response. I don't think any of it is specific to them, just plug in the right variables.
HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create((transaction.TestRequest) ? testurl : url);
objRequest.AuthenticationLevel = System.Net.Security.AuthenticationLevel.MutualAuthRequired;
objRequest.Method = "POST";
objRequest.ContentLength = strPost.Length;
objRequest.ContentType = "application/x-www-form-urlencoded";
try
{
myWriter = new StreamWriter(objRequest.GetRequestStream());
myWriter.Write(strPost);
}
catch (Exception e)
{
return null;
}
finally
{
if (myWriter != null)
myWriter.Close();
}

dear christian
i already send my variables while clicking "Buy Now" button the problem is when they send back IPN to my url(ex:55.62.65.23/paypal/anything.aspx)
the anything.aspx page should read the sent variables (ex:transaction_id...) so what classes or method read and store it in my database or XML file
thanks a lot

HI
U r sending all the required parameter to paypal via query string or
by hidden field. If u r payment got successed then user will be
redirected to success_url. Then it will send you all the values
via query string. U can read this values as follows.
dim tid as string = Request.QueryString.Get("txn_id")<br />
dim amt as string = Request.QueryString.Get("payment_gross")
Paypal will send to all information about to payer and the merchant.
you can read all the values through query string.
Regards.
Rahul

Hi All,
I created listener for POST message from client as a simple web page and process that message in Page_Load method. If I use url for posting message to my listener with explicit web page name http://myserver/formhandler/listener.aspx it works without error. But my clients will need to post message using url without mentioning page name like this http://myserver/formhandler. In IIS for formhandler virtual directory I set default document as listener.aspx. And now my issue starts: server responds every time with error 405 Method not allowed. I set properly mapping for aspx extension in configuration to allow POST method.
I would greatly appreciate if anyone can point me what else I have to set to overcome this issue.
Thank you very much in advance,
Roman

Hi,
I'am ASP.NET 2005 and I am trying to check size of an upload file and limit user if file size>1000kb? I success to limit user for upload only pictures, as following my code.
I need the code in Javascript, I already did it at server side validation.
<script language="javascript" type="text/javascript">
function onSubmitForm(source,arguments)
{
var formDOMObj = document.getElementById("ctl00_ContentPlaceHolder1_UserDataFormView_FileUpload1");
var vld=document.getElementById('ctl00_ContentPlaceHolder1_UserDataFormView_VldUpload1');
var isvalid=false; //Init
if (formDOMObj.value != "")
{
//File type
var strLocation = formDOMObj.value;
var strFile = strLocation.split(".");
var arrFileExtension = new Array(7)
arrFileExtension[0] = "JPG";
arrFileExtension[1] = "JPEG";
arrFileExtension[2] = "GIF";
arrFileExtension[3] = "BMP";
arrFileExtension[4] = "TIF";
arrFileExtension[5] = "TIFF";
arrFileExtension[6] = "PNG";
var len = arrFileExtension.length;
var x=0;
for (x=0; x<len; x++)
{
if (strFile[strFile.length - 1].toUpperCase() == arrFileExtension[x].toUpperCase())
isvalid = true;
}
if (isvalid==false)
{
vld.errormessage="jpg jpeg png gif bmp tif tiff ";
arguments.IsValid = false;
return;
}
}
//Now check file size
??????????
arguments.IsValid = isvalid;
}
Please help

I think you probably need to use Server-side script for that.. In server-side, you can use this code FileUpload.PostedFile.ContentLength to get the size of file..

Thanks but as I said I already did it at server side. This is not the bet thing because before server side validation the posatback clear the fileupload textbox
