I am a little confused as to what your are trying to do. If I read your replies right then you want a PC, with two serial ports, each connected to a modem. The two modems are connected together (presumably via two telephone lines, or else you will need a null phone connection with a battery.
You then want to transfer files from the PC to the PC via the modems? If so, then odd, but do-able.
I would just eliminate the modems and use a null-modem cable if there was a good reason for this.
Talking to the modems: http://www.atarimagazines.com/compute/issue131/33_talktoyourmodem.php[^]
Try it using two Hyperterminals on separate com ports and you should see what is happening (and if all the H/W is working).
Then in C#, you will need two instances of the SerialPort class to replace the hyperterminals.

Take a look at the documentation for the ToolTip control. You don't even need to look at the individual methods/properties, the summaries give enough information.

I haven't had that problem.
You did a release build?
You made an installer that:
Includes the "primary output" of the application project?
Creates the file association?
Then installed on the target system (which has .net) and it doesn't work?

Thankyou

Hi,
set ListBox.SelectionMode to one of the Multi modes, then use either ListBox.SelectedIndices or ListBox.SelectedItems

Hi
i have a dataGridView and bindingSource in my form and i fill my gridView with this two lines of code :
DataManager dm = new DataManager();
this.frmDataSet.Ground.Merge(dm.GetGrount(Guid.Empty.ToString()));
it display data in dataGridView correctly. now i want to load data with backgroundWorker. for this i modify above code as follow :
this._frmLoading = new FrmWait("Please wait", "Loading data ...");
this.backgroundWorker1.RunWorkerAsync();
here is my backgroundWorker event handlers :
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
DataManager dm = new DataManager();
this.frmDataSet.Ground.Merge(dm.GetGrount(Guid.Empty.ToString()));
}
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
if (this._frmLoading.IsShowing)
this._frmLoading.Close();
}
at runTime, all code works correctly but data does not display in dataGridView, when i trace my app my dataSet has rows but i don't know why dataGridview could not display this data with BackgroundWorker.
can anybody help me ?
thanks

Is the DataView bound to the dataset? In that case, updates on the data set will cause the dataview to update as well, and those updates will occur on the background worker thread, instead of the UI thread.
Did you try unbinding the dataview, merging it in the background, and then binding it again?

Hi, I developed an Client / Server application, the problem is the following:
- when a wrong IP address is inserted in the Textbox, Client application freeze.
TcpClient socketForServer;
try
{
socketForServer = new TcpClient(Ip, Port);
}
catch (Exception e1) {
info._error = e1.ToString();
return info;
}
What I can do?

You will want to start running your TCPClient on a different Thread so it doesn't lock up the GUI thread while waiting for a timeout or connection refused.
So do the following
ThreadPool.QueueUserWorkItem(new WaitCallback(<function that="" starts="" the="" tcpclient="" connection="">));
Keep in mind that the Drawing of items can only be done on the thread they were created on (usually the main thread) so setting text and that sort of thing should be done by invoking the functions using the Invoke function
|

|
|
Alternatively you can also use the asynchronous methods of TCP client to make your connection, BeginConnect and EndConnect
|
|
|

there are couple of things that you may do
1. Application.DoEvents()
2. You need to set socketForServer to null in case an error occurs, it will be creating a new object every time and will become a source of memory leak.
