Can we block internet to client systems where
1. both server, an internet connection and client system are connected through a single hub or switch.
2. both client and server uses windows xp OS
The software which has to be develeoped uses Winforms where both client and server have 2 different set of applications. The client application provides an login option. when the user types in the login information, the information is sent to the system considered as server, authentication is done and if the login information is valid internet has to be provided to the system considered as client.
The internet should not be provided if the client application is installed and it is not running in the client system. Only if the client application is running and login is authenticated, the internet connection has to be provided to the system.
This software is developed for college project purpose. Can anyone assist me or send me the web service code such that internet connection is provided to client only after server authentication. And also how the server and client has to be connected through hub/switch in detail.

Even i am trying something like that, but my requirements are a bit different. I have a Windows Server 2003 enterprise standard acting as web server and a well defined network architecture using Sonic Wall as firewall and 3com network switches. Sonic Wall has limited functionality, so that's y i also have such a requirement of blocking a couple of users to all websites except a few business related sites. Once i complete it, i would be happy to guide you although i also have a vague idea of such a thing.

I created a table in sqlserver database.Now, i want a code by which i can get the list of data of specific column of that table(eg. C_ID)in combobox in front end.

Assuming you're returning a DataSet[^] that contains one DataTable[^] that has two column[^]s, then this works.
Adapt to your specific situation.
comboBox1.DataSource = ds.Tables[0];
comboBox1.DisplayMember = "Display";
comboBox1.ValueMember = "ID";
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

why you making this so complicated ?
First search for a number, then convert it to byte[] then merge all array elements in sql varchar data type. Is this you are trying to do ?
If you wanna store byte[] in sql then you should use "Image" data type.

I will try to run the nlp project. I don't know how to conver the ".nbin" file to ".bin".
|

F2 lets you rename a file. If you need to convert between formats, then you need to read up on the formats and write a converter.

Hi everyone,
I know this's a lame question but what is the shortest way to modify a control in a separate thread without raising the cross-thread exception..
I basically have this datagrid control and when changing its databinding properties, it's binding fine except it doesn't show it correctly.
Please help guys!

you can turn off the cross thread exception if you want to. That's the quickest way to do it.

it also is the quickest way to a disaster. I never understood why MS introduced this property,
I see no use for it whatsoever. The use of InvokeRequired/Invoke, either explicit or hidden as in BackgroundWorker events, is mandatory.

Usually, I'm using BeginInvoke with an anonymous method:
string newValue = ...;
BeginInvoke(new Action(delegate {
theControl.Property = newValue;
}));
You have to be a bit careful with BeginInvoke as it's always an asynchronous call; when called from the GUI thread it will delay executing the delegate until your code returns to the message loop. And you have to be careful what variables you use in the delegate - e.g. if you use a loop variable, it might have changed to the value for the next iteration before BeginInvoke calls your delegate.
But BeginInvoke is faster than Invoke because it doesn't have to wait, and it doesn't have the potential for deadlocks.

I thought it would be possible to add a static event handler and attach to it from outside the form code add the event listener then instantiate the form with Application.Run(new Form()).
Inside the Form, the Event gets fired, and then calls Form.Close(), Application.Exit() on the Sender object (the Form) but I get an error that I cannot access an Disposed object.
I thought this would be possible if the EventHandler was static I thought it would not care if the object was disposed.
Thanks for any help guys sorry I am a newbie to UI programming.

Not sure I got your question. Please post relevant code so that we understand what you are saying.

Thanks Navaneeth,
Here is an example of what I am trying to do:
// Entry Point:
DummyForm.TestsFinished += new EventHandler(DummyForm_TestsFinished);
// Start Processing the query
// viewFrameworkDummyForm.ProcessQueryInstructions(queryInstructions);
// Start the Application message pump (the viewFx has to be run on a form to be contained within a thread UI)
DummyForm myForm;
// ****************************************
// I get a Cannot access disposed object ex on this below line:
// ****************************************
Application.Run(myForm = new DummyForm(queryInstructions));
// DummyForm:
public partial class ViewFrameworkDummyForm : Form
{
private List&lt;QueryInstruction&gt; queryInstructions;
public static event EventHandler TestsFinished;
/// <summary>
/// Constructor
/// <summary>
void DummyForm(List<QueryInstructions>queryInstructions)
{
…
// Does stuff with query instructions…
…
// Event gets fired somewhere in the constructor…
OnQueryInstructionsProcessed(this,new EventArgs());
…
}
// Notifies the attached events to QueryInstructionsProcessed, that the query instructions have been processed.
void OnQueryInstructionsProcessed(object sender, EventArgs e)
{
//Inform that the tests have been finished, and then close the form..
TestsFinished(this, new EventArgs());
this.Close();
Application.Exit();
}
}

i wanna pull multiple records in from a database and display them in different labels
I was thinking of returning them in an array then adding them to the specified labels, can anyone point me to the an example or aid me.
sample code
public partial class _Default : System.Web.UI.Page
{
SqlConnection con = new SqlConnection("server=BABOO;uid=sa;password=sa;database=quiz");
protected void Page_Load(object sender, EventArgs e)
{
con.Open();
string query;
query = "select QuestionText,AnswerA,AnswerB,AnswerC,AnswerD from quest where QuestionID='1'";
SqlCommand cmd = new SqlCommand(query, con);
SqlDataReader dr;
dr = cmd.ExecuteReader();
while (dr.Read())
{
nt rbCount = Convert.ToInt32(TextBox2.Text);
RadioButton[] radioButtons = new RadioButton[rbCount];
for (int i = 0; i < rbCount; ++i)
{
radioButtons[i] = new RadioButton();
radioButtons[i].Text = dr.GetValue(1).ToString();
}
Please i need your help

So, this seems a little retarded to me.
1 - you want to have a textbox showing how many answers to show ? So, what if the right answer gets hidden ?
2 - how do you make sure that textbox2 contains a number ?
3 - why don't your variables have real names ?
4 - You're reading the same value from the answer list every time
5 - you never add the radio buttons to your UI
