Is there a "Tapi" code in C#
|
|
|
|
|
There is no TAPI support in the .NET BCL. You'll have to go through the pain of P/Invoke'ing all the calls and rewriting all the structures they need in C#. From other answers posted to the same question on CodeProject, it's royal pain in the *** to do. It's been recommended against doing it several times.

I have created a multiple client chat window program in which I want to create a new chat form and show it when the client gets the chat request from another client. When the communication socket thread for the client receives the chat request and tries to create a new form and show the form, it is not displayed since the communication socket thread is a worker thread. Can anybody has solution for this?

You'll have to invoke this, so it's executed in the context of the UI Thread. Take a look at the documentation for the Control.Invoke[^] method.

The easiest way is to let the UI thread do the display. Here is an example of how I handle an event fired from a working thread in my code. I learned this technique from a set of excellent articles by Chris Sells on MSDN. The key is using the forms InvokeRequired property and Invoke method.
private void RaiseProgram(object sender, EventArgs args)
{
if (InvokeRequired)
{
object[] objs = new object[]{sender,args};
this.Invoke(new EventHandler(RaiseProgram),objs);
return;
}
textBox1.Text = RunOnce.OtherAttemptCount.ToString();
if (this.WindowState == FormWindowState.Minimized)
{
this.WindowState = FormWindowState.Normal;
}
RunOnce.BringFormToFront(this);
}

I have created an application. Here I am giving the code for the form file in the application in which I am trying to show a new form when the timer expires after 2 seconds. But the form is not displayed properly. When the button on the form is clicked it properly shows a new form. So please let me know what is going wrong here?And how to correct that.

You are having a UI Threading problem. This will fix your current issue but I don't like the whole solution.
You are very dependent upon the line Application.Run(). That is where the UI thread enters the message loop. I would make the timer dependent upon the creation of Form1. It would still have to be static so that you do not create another each time the form loads. I am not quite sure what you are trying to accomplish so I didn't change your current pattern too much here.
static Form1 mainWindow = null;
[STAThread]
static void Main()
{
System.Timers.Timer aTimer = new System.Timers.Timer(2000);
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
aTimer.AutoReset = false;
aTimer.Enabled = true;
mainWindow = new Form1();
Application.Run(mainWindow);
}
private static void OnTimedEvent(object source, ElapsedEventArgs e)
{
if (mainWindow != null)
{
mainWindow.button1_Click(mainWindow,EventArgs.Empty);
}
}
private void button1_Click(object sender, System.EventArgs e)
{
if (InvokeRequired)
{
object[] objs = new object[]{sender,e};
this.Invoke(new EventHandler(button1_Click),objs);
return;
}
Form1 oForm1 = new Form1();
oForm1.Show();
}

Thank you for the help. That worked perfectly. I know that the application I have created was very crude one but it was the one to help me in the real problem.
Actually as I had written in the first mail that I was having problem to create form when I get the chat request in a chat application where I was unable to diplay the form properly. It worked when I made some changes getting the information from your help. Thanks again.

Glad I could help - I learned from the master Chris Sells. He has written a series of 3 articles on the subject for Microsoft. They are very clear and understandable.

Hy,
I want to create a Remoting server but all examples I've found shows
how to create a console application. I want my server in a windows service.
The problam is that the process has to be running after the command
RemotingConfiguration.Configure(); and I cannot use Console.readline().
Anyone could show me an example of how to create a .NET Remoting Server using a windows service.
Thanks.

Hi!
It doesn't matter whether the service is run as a console application or as a windows service.
The only reason for Console.ReadLine() in the samples you've found is that otherwise the application immediately quits and the server will be disposed off.
When you're doing the exact same things in a windows service, the executable is running while the service is running and the remoting server can be shut down by stopping the service.
Configure your remoting server in the Start event of your service and you should be fine.
Regards,
mav

I actually did this and it works fine, but I ran into one additional problem. I am using a singleton object with essentially an infinite life time. When the service is stopped, The system still seems to think the remote object is registered and allows a proxy to be generated. Now when the client uses the proxy, it get's an exception. I can't find an unregister function in the remoting class. Is there anyway to make the remote object go completely away?

Hi
I'm a beginner, but this should still be a simple task. I want to insert some data to my access database. I can run my project, but when I try to insert the data this error message appears: "Operation must use an updateable query"
This is my code:
OleDbConnection conInsertNews;
string strInserNewst;
OleDbCommand cmdInsert;
conInsertNews = new OleDbConnection( "PROVIDER=Microsoft.....);
strInsertNews = "INSERT INTO Test ( Name, Number, Adress ) VALUES ( 'Bob' , '8' , 'Str A' )";
cmdInsertNews = new OleDbCommand( strInsertNews, conInsertNews );
conInsertNews.Open();
cmdInsertNews.ExecuteNonQuery();
conInsertNews.Close();
Can anyone help me with this?
Thanks!!

Try replacing

with
LoginGrid.DataSource=LoginSet.Tables[0];
Also, are you certain that there is data in this table ?

Hi Sreejith
Thanks for your help. I have looked at your article, and although very interesting, does address my question entirely.
As well as iterating through my custom class collection, I would also like to have the Add, Remove and Item fucntions available to me too.
Is that something which can be easily incorporated into your Example2?

Enumerators only allow reading the data in the collection. Enumerators cannot be used to modify the underlying collection
An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying or deleting elements, the enumerator can be invalidated and the next call to MoveNext or Reset can throw an InvalidOperationException.
But don't worry give me some hours, sure i will comeout with an idea.

Hello,
How can I delete a string-value (NVarChar Type) in an easy manner from a Sql Database? I think the SQL Statements looks like - DELETE columnname FROM tablename WHERE Email=?
But how does look like the programm code?

Hello,
I'm writing a custom DataGrid and in it i want to have some default actions occur. For example, what I have now, I cannot edit any rows (I only select full rows), multi-row selection is allowed, and the delete key will delete all currently selected rows.
But then there's this weird factor. When I press the up arrow key, I want my currently selected row to move to the previous one (the general case), and vice versa when I press the down key. But when I push Up, Down, Left, and Right (along with some other different keys), the KeyDown event handler for the DataGrid isn't called. Instead, the column style Edit event handler is called.
I thought I could just create a new event that would call an event handler from inside the Edit handler; however I would have no means to send off which key was pressed.
Does anyone know how to do this? I've been thinking about this and searching for what I need to override in order to do this, but to no avail. Can anyone help?
