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..
Regards,
-SIFAR.

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... 
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

Hidden field, use Request.Form instead:
string fname = "";
if (Request.Form["customer_fname"] != null)
{ fname = Request.Form["customer_fname"]; }
Response.Write("fname value: " + fname);
Regards,
Gary

can someone put a code snip here that i can use to determin if a adusers is disabled
|
|
|
|
|

i tried this method to see if i could figure out if the user was disabled but i get and error i just wanted to see if i would get a 0x1 if the user account is not disbled and a 0x2 if it was
public void Disable(string userDn)
{
try
{
DirectoryEntry user = new DirectoryEntry(userDn);
int val = (int)user.Properties["userAccountControl"].Value;
\\ get the error on the above line
user.Properties["userAccountControl"].Value = val | 0x2;
//ADS_UF_ACCOUNTDISABLE;
}
catch (System.DirectoryServices.DirectoryServicesCOMException E)
{
//DoSomethingWith --> E.Message.ToString();
}
}
|
|
|
|
|
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;
}

I've just started getting this for every breakpoint within a specific assembly.
"The breakpoint will not be hit, no symbols have been loaded for this document" I'm using a debug build, so what happened?

Delete everything in your debug folder and clean your solution and rebuild, happens to me occasionally. This usually fixes it.

Not this time.

You deleted your .pdb files as well? Close VS, delete pdb and binaries, open, clean solution and build.
Should solve it. Has to do with timestamps of builds not being updated, IIRC that info was held it the pdb files, deleting them, reopening VS with a clean solution / build solved it.
Give it another whack.

|

Yes.
I deleted the following folders with the solution closed:
<all projects="">\bin\debug\
<all projects="">\bin\release\
<all projects="">\obj\

Sorry, that's what did it for me if I remember correctly. I can't remember if I deleted the .suo and .ncb files as well, but that might damage your solution and I don't want to corrupt your data.

I would do a rebuild all and see what happens.

Assuming you meant rebuild solution that didn't work.

Assuming you deleted all the files, that must mean that you're sure the exe you're running, is being build every time ?
I'd love to know what the root cause is, it sounds quite bloggable. ( http://thingsihateaboutmicrosoft.blogspot.com/[^] )

As as I can be without having the vista task managers option to find the path to the processes executable. I managed to fix it which is half way to the root cause...
I had two copies of the project on my start page. My normal build path, and a second leading to an second copy pulled from source control in a different location on my drive (a coworker had an odd issue after I checked something in and I wanted to make sure I didn't leave the source control with a version dependent on a non controlled file). I was opening the former, and all its bin\obj files were being rebuilt after deletion, but the problem went away when I deleted the bin/obj files from the second. Dunno any more about how it apparently managed to cross link something from the two copies.
My laptop LCD's borked and won't be replaced until today or tomorrow, but after that I can play around with this a bit at home if you've got any ideas on how to determine what the RC is.
We're using clearcase on this program (with the VS plugin) so it possible it is rational at fault not MS.
