GetForegroundWIndow returns integer value. and pass it to GetWindowText.

you can use it by using hook.
Obvious you are changing application by Mouse or Keyboard.
By using hook u can check it in Keydown or mouse event.

Helo Every 1,

I want to receive files via MODEM and files are being transferred by XMODEM. I am using C# and want to receive files from different MODEMS.

What is the way to receive and send files by XMODEM using c#? I can do it by Hyper Terminal but I want to do it in my code.

Any Suggestion will be very helpful..

Thanks in advance..

I have been hunting for over a week to understand xml. I have no Idea why the concept of how to use it alludes me. Sorry in advance. This is a real noob question.

I have built an application that manages the installation and updates several of our packaged products. The problem is All the settings are stored in sql tables.

I just need to understand is:
1)How to create a XML file that stores the connection string
2)How to refer to that XML file to use the connection string in the application.
3)If the file gets deleted, how to have the application recreate a template with a default connection string.

My Application is C#

Any information directly or indirectly would greatly be appreciated. This project needs done by the end of the week. And this is the only part I can not figure out.

You can use application configuration file (app.config) for that. It is in XML format. There is a appSettings[^] element where connection strings can be stored. ConfigurationManager.AppSettings gives you access to this element.

I tried that but I can not seem to get the value to return properly... Here is what I do..

I go to the application project manager,
right click on project
Say properties
Go to the settings tab and put

Name: SQLConnectionString
Type: string
Scope: Application
Value: "Data Source=PA-DEVPLATFORM1\SQL2005;Initial Catalog=AppLoader;Persist Security Info=True;User ID=Mike;Password=zephyr"

This SQLConnection String I am wanting in a external XML file editable to the end user so I do not have to recompile the application for every sql server change.

Here is the code I am using to call it. It does not work.
SqlConnection conn = new SqlConnection(Properties.Settings.Default.SQLConnectionString);

I can not seem to get
ConfigurationSettings.AppSettings
to be identified as a valid command...

I got close by adding
public static NameValueCollection AppSettings { get; }

but the applications says it needs a set added to it.

PLEASE any help on this?

----------------------------------------------------------

So far I have figured out to get the setting I think I need to do this?
SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationSettings.AppSettings["SQLConnectionString"].ToString());
But it still comes back saying the string is null... Why?

Got it....

string testanswer = PeerAssistLoader.Properties.Settings.Default.SQLConnectionString.ToString(); //["SQLConnectionString"].ToString();
MessageBox.Show(testanswer);

I had the value in the settings with quotes around the connection string. Since I was viewing that field as a string value. Now I know better...

If you want it editable by the end user, I would create my own using XMLDocument - there is a big risk of the user damaging other application settings by mistake if he is encouraged to edit the app.config file directly.

See Here[^] for an example.

As Navaneeth says above, you probably want to use an app.config file for storing your connection string.

There are two ways of storing the connection string in said file.
The first is quick, dirty and I don't like it, but I'll show you anyway... Dead | X|

The connection string can be stored within the "appSettings" section of your app.config file, as follows:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
	<appSettings>
		<add key="MainDB" value="Data Source=127.0.0.1;Initial Catalog=MainDB;User ID=usr;Password=pwd"/>		
	</appSettings>	
</configuration>

To then read this setting from within your c# app, you'd need to use the following code:

System.Configuration.AppSettingsReader reader = new System.Configuration.AppSettingsReader();
string connString = (string)reader.GetValue("MainDB", typeof(string));

The reason I don't like the above method, is because the app.config specification includes a section specifically for connection strings.

Below is an example of an app.config that uses this section:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
	<connectionStrings>
		<add name="MainDB" providerName="System.Data.SqlClient" connectionString="Data Source=127.0.0.1;Initial Catalog=MainDB;User ID=usr;Password=pwd"/>		
	</connectionStrings>
</configuration>

To then read this section, you first need to add a reference to "System.Configuration" to your project.
Then, you can use the code below:

string s = System.Configuration.ConfigurationManager.ConnectionStrings["MainDB"].ConnectionString;

Much nicer Cool | :cool:

Hidden field, use Request.Form instead:

string fname = "";
if (Request.Form["customer_fname"] != null)
{ fname = Request.Form["customer_fname"]; }
Response.Write("fname value: " + fname);

Sorry, I don't quite understand what it is you want, but I found this article[^] here on codeproject which seems to deal a lot with the active directory, should have something about what you are trying to get information on.

If not, try any of the following hits:
1[^]
2[^]

Sorry I couldn't be of more help.

Edit:
Some more links on codeproject about querying / interacting with the AD;

First Link - deals with querying the AD[^]
Second Link - deals with authentication[^]
Third Link - More querying AD[^]

Let me know how it goes.

This is what I use passing in the DirectoryEntry object as a paramater.

public static bool CheckAccountDisabled(DirectoryEntry de)
{
        int ACCOUNTDISABLE = 0x0002;
	int flags = (int)de.Properties["userAccountControl"].Value;
	if (((flags & ACCOUNTDISABLE) == ACCOUNTDISABLE))
	{
		return true;
	}
	return false;
}
