hi subrat,
if you want to submit post data you can create a weburi using webrequest object
and set the parameters like
WebRequest req = WebRequest.Create("URL to be accessed");
req.Method = "POST";
req.ContentType = "text/xml";
string str = "POST DATA";
StreamWriter sw = new StreamWriter(req.GetRequestStream());
sw.WriteLine(str);
sw.Close();
WebResponse res = req.GetResponse();
and res will contain response from the accessed URL.
you can read response using stream readers.

Using the Request.Form collection.
As you are talking about the "next page", it seems that you would want to post a form in the browser, not make a request from the server. Is that correct?
Despite everything, the person most likely to be fooling you next is yourself.

What does this have to do with globalisation ( or indeed, with ASP.NET ) ???

Hi, i have done one application which tooks input as excel file which contains 2 columns. i took whole excel data to datatable and add two more columsn to datatable and export this data table to csv file by creating file programatically . The application is running sucessfully in my local machine. So i deployed in server. it working fine, when i logged into that server and run from there.
If i run the deployed application from my local machine using
http://192.168.1.110/Myapp/uploadfile.aspx. I am getting the following error.
"The Microsoft Office Access database engine cannot open or write to the file ''. It is already opened exclusively by another user, or you need permission to view and write its data" (IF i took .xlsx file)
"The Microsoft Jet database engine cannot open the file ''. It is already opened exclusively by another user, or you need permission to view its data."(IF i took .xls file)

I think you have the file open and are trying to use that.
Close the file and retry.

I have placed the following code on a web page. It works fine on the development machine. But when I publish the web site to the production server, this object is never rendered. An Internet Explorer error is displayed: Object doesn't support this property or method. I get this same error on the local machine if I change the url to an incorrect url. This is a TXTextControl project. I am at a total loss as to why this will not function on the production server. Any help would be appreciated.
<object classid="http:BrowserBin/BKDocuments.dll#BKDocuments.DocBrowserAppControl"
id="DocBrowserApp" name="DocBrowserApp" width="800" height="500">
</object>

For this to work, the control needs to be registered on the machine that views your site. There are bound to be other security issues also. Best approach is don't do it.

I get
$exception {"Index (zero based) must be greater than or equal to zero and less than the size of the argument list."} System.Exception {System.FormatException}
when trying to testing this code
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
namespace FileWatchingDemo
{
class Program
{
static void Main(string[] args)
{
FileSystemWatcher watcher = new FileSystemWatcher(Environment.SystemDirectory);
watcher.Filter = "*.ini";
watcher.IncludeSubdirectories = true;
watcher.NotifyFilter = NotifyFilters.Attributes | NotifyFilters.Size;
watcher.Changed += new FileSystemEventHandler(watcher_Changed);
watcher.EnableRaisingEvents = true;
Console.Read();
}
static void watcher_Changed(object sender, FileSystemEventArgs e)
{
Console.WriteLine("Changed: {1}", e.FullPath);
}
}
}
It seems this line
Console.WriteLine("Changed: {1}", e.FullPath);
has problem but I just don't know how to solve it.
I am new to ASP.NET and please help!!

Are you doing it in ASP.NET ? 
|
|

Arrays in programming are 0 indexed. You specify {1}, which means the second argument, but you only provide one. Replace the 1 with a 0.
And as someone else said, this doesn't look remotely like ASP.NET code. In fact, it isn't.

Dim results As DataView = CType(SqlDataSource1.Select(DataSourceSelectArguments.Empty), DataView)
Dim PictureIDJustAdded As Integer = CType(results(0)(0), Integer)
'Reference the FileUpload control
Dim imageUpload As FileUpload = CType(DetailsView1.FindControl("imageUpload"), FileUpload)

If the files are just stored in the file system, how do they stay associated with the rows of your grid as you add them ?

I'm working on my first ASP.NET application ever, so this might be an easy problem to solve for you.
I'm collection data from different xml files and want to store them in an DataSet.
The data will be shown with an repeater.
The page will show something like this: (Short version, will be lots of more information)
Miami Engineering
1. General
Doc one
Doc two
2. Feasibilty calculations
Doc three
Doc four
Doc five
When I try to add the data to my DataSet the way I was thinking, I get the error "A DataTable named 'Document' already belongs to this DataSet."
This is when I try to make a DataSet with this structure:
<projects>
<project>
<projectname> Miame Engineering <projectname>
<project>
<part>
<partname> 1. General </partname>
</part>
<document>
<documentname> Doc one </documentname>
</document>
<document>
<documentname> Doc two </documentname>
</document>
<part>
<partname> 2. Feasibilty calculations </partname>
</part>
<document>
<documentname> Doc three </documentname>
</document>
<document>
<documentname> Doc four </documentname>
</document>
<document>
<documentname> Doc five </documentname>
</document>
</projects>
How will I build my DataSet so I can get the output that I want?

I am not sure why you're using a dataset, but it doesn't look to me like the data you're using is compatible, unless you specify a maximum number of doctors.

I'm using a DataSet because I want to be able to add, delete and change data in it.
What do you mean with specifying maximum number of documents?
Haven't seen that option, so how do I do that?

This is a tree, with three levels. You would have to create three tables and define the relationship between them, to reproduce this structure. Not sure if .NET is smart enough to do that by itself.

i have a problem. please help.
user control is dynamically added when gridview is selected( invoice number is selected) so far so good. but when a second selection is made
the previous control appears again, naturally. so i want to register usercontrol a new every time grid is selected, how can i do that?
|
|
|
|

What do you mean by 'register' ? I think you want to create one control, and then move it if it already exists, b/c viewstate is causing it not to be removed ( or just explicitly remove from all rows but the selected one when you add a new one )
