I have a design task! Please advice me which are the technologies to use.
The simple block diagram:
____________ ______________________ _________________
| | | | | |
|TCP Server |----------|Web Server (asp.net) |---------------| Web browser |
| socket | | c# | | |
____________ ______________________ ________________
The web server has to connect to TCP server socket as a client.
The data sent by TCP server has to be forwarded to appropriate
browser(every browser has a unique number & this number will be
attached in data). TCP server sends data asynchronously.
It should be possible to send a data from web server to TCP server
on a request from browser(along with unique number).
Please guide me how to forward the data received from TCP server
to unique browser.
Thanks in advance,
Nissar

Why do you want to delete them? You can hide them on click of a button.

Open notepad, enter the following code and save the file "YourFileName.cs" without the quote marks. This should ensure using C#.
using System;
using System.Collections.Generic;
using System.Text;
namespace ConsoleTest
{
class Program
{
static void Main(string[] args)
{
}
}
}

Include Microsoft.Web.UI.WebControls.dll in your project.
For runtime addition of nodes for TreeView control do following steps
//On aspx page register TreeView as
<%@ Page language="c#" Codebehind="TreeControl.aspx.cs" AutoEventWireup="false" Inherits="UserControlApplication.TreeControl" %>
//Treeview Control
<tc:treeview class="link" id="tree1" runat="server" indent="15">
//Add the root node for User Control Tree1 in .cs file
TreeNode tNode = new TreeNode();
tNode.Text="Root";
tree1.Nodes.Add(tNode);
//Add Child Node to root node tNode
TreeNode tChileNode1 = new TreeNode();
tChileNode1.Text = str;//This string is the information retrieved form database
tNode.Nodes.Add(tChileNode1);

Might help if you can tell us what the problem is. What I have done in the past is to upload the file, then read it using OLE DB.

Launch Excel 2003 then open the workbook file you'd like to upload. Choose from the menu File-->Save as Web Page.
Then using IE7(or IE6 if you want) direct your browser to the ftp://your_ftp_addy . Drag the Excel file that you have saved as a web page from your machine directory to the web directory of your choice.
The rest is simple...or should be intuitive.

Hello,
I have created a function which creates a DataTable from a Database.
However, I want to be able to use an Access or aSQL database.
Do I need to create 2 complete different functions?
The method is the same, only the types change.
Here is my code:
' Define connection
Dim connection As New SqlClient.SqlConnection(connectionString.ToString)
' Define command
Dim command As New SqlClient.SqlCommand
With command
.CommandText = "GetRecords"
.Connection = connection
.CommandType = CommandType.StoredProcedure
End With
' Add command parameters
With command.Parameters
.Add(New SqlClient.SqlParameter("@Value", Value))
End With
connection.Open()
...
Create DataTable
...
connection.Close()
Thanks,
Miguel

In the data access layer create data objects of SQL and Access depending on the type and in the business layer access the object through nterfaces IDataSource, ICommand etc.

That pro'ly will not work if you're looking to use a Microsoft Access database.
Here's a bit of code for you that should help connect to your Access db.
/ Assumes connectionString is a valid connection string.<br />
using (OleDbConnection connection = <br />
new OleDbConnection(connectionString))<br />
{<br />
connection.Open();<br />
Remember to add the OleDb namespace with the following: using System.Data.OleDb; or all your coding will be for naught.
For further reading on the subject direct your browser of choice (I recommend IE7) to http://msdn2.microsoft.com/en-us/library/system.data.oledb.aspx[^]
Good Luck!

I have an ASP.Net web application with a few pages. I have centered the buttons, textboxes, and images on the pages at the resolution of 1024 X 768. I use VS2003 Designer to create the pages. The problem I have is that whenever the pages are displayed at a different resolution, like 800 X 600 or 1280 X 1024 the buttons, textboxes, and images are not displayed correctly. They are too large and off center at the lower resolution and too small and off center at the higher resolution. Is there a way for me to display my pages correctly at whatever the resolution is using C# in the codebehind, set some property for the controls, or using javascript to adjust the controls at the appropriate resolution? Any help would be appreciated, thanks.

You can try placing a gridlayout panel in a table and center the panel.

Target your web application for a particulare resolution or control the UI properties by using % (percentage) instead of px (pixels)

I'm trying to create an installer project that takes the output from building my webapp and creates an installer.
Everything works fine, the only issue is that I have to manually go into the IIS configuration tool and change the asp.NET version number from 1.1 to 2.0 in the webapp properties.
Is there any way to make it so the webapp is automatically configured to use asp.net 2.0?

I have set up a page to preview images and then upload them. Using VB in a .NET page. All is good. However, some images do not display, the only common theme I have been able to find is that all the images that do display correctly have camera information attached. I don't get it, and I am feeling veeeeery shtupid. Can anyone tell me why this is and if there is a way to get around it, without uploading the file first?
A newbie (but working on it!)

Hello,
I need to create a new XML document.
I believe I need to do this at runtime because the new XML document uses two sources for its data:
1. ASP.NET 2.0 Web.sitemap (It is a XML file)
2. Data which is stored in AppSettings Keys on Web.Config.
The ASP.NET 2.0 Web.sitemap looks as follows:
<?xml version="1.0" encoding="utf-8" ?>
<siteMap
xmlns = "http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode>
<siteMapNode
url = "~/default.aspx"
changefreq = "Daily"
description = "My Desgription"
priority = "0.5"
title = "Description"
google = "true" />
</siteMapNode>
<siteMapNode
... />
</siteMapNode>
</siteMap>
My questions are:
1. How to create the new XML document and add the following:
<?xml version="1.0" encoding="utf-8" ?>
<siteMap
xmlns = "http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
2. How to loop through all "siteMapNode" nodes of Web.sitemap and create the following transformation:
<siteMapNode
url = "~/default.aspx"
changefreq = "Daily"
description = "My Desgription"
priority = "0.5"
title = "Description"
google = "true" />
TO ( IF google EQUALS "true")
<siteMapNode
url = "~/default.aspx"
changefreq = "Daily"
description = "My Desgription"
priority = "0.5"
title = "Description"
google = "true" />
< url>
< loc> # Value created from AppSettings Key + Web Site Map "URL" Attribute # </loc>
< changefreq> # Value created from Web Site Map "ChangeFreq" Attribute # </changefreq>
< priority> # Value created from Web Site Map "Priority" Attribute # </priority>
</url>
Yes, I know I could do this with a XSLT file. In fact I did that and it is working.
My problem is that I need to introduce some data which I get from AppSettings Keys in my Web.Config.
For that reason I think I completly lost that possibility.
UNLESS I would be able to, in my XSLT file, access an Application Setting Key from my web.config file. I believe this is impossible, right?
Thanks,
Miguel
