|
|
|
any way the application is depend on the distributed systems , so i want to just access to the other machine so you can say that i want to make remote desktop like that in windows ....
what can i do with c# ?
|
|
|
|
|
|
how to get number of records selected?
SqlDataReader dr1 = cmd1.ExecuteReader();
|
|
|
|

I don't think you can tell ahead of time how many records will be returned. If you need to know that, then you can use a COUNT function in your SQL or loop through the records and count them as you go.

The other way will be to use a dataset and do a count of that dataset:
SqlDataAdapter sqldataadap = new SqlDataAdapter(objCmd); //objCmd is your Sql Command Object
DataSet ds = new DataSet();
sqldataadap.Fill(ds);
//get the # of rows:
int irow=ds.Tables[0].Rows.Count;
|
|
|
|
|
After running any type of query just fire following query to know
number of rows affected.
SELECT @@rowcount AS 'RowsChanged'
Hope this will help!

Fill a data adapter with a dataset. Then count the rows.
Some thing like:
int totalRow = Dataset.Tables[0].Rows.Count;
|
|
|
|
|
The reader does not have a count.
You could however use an ExecuteScalar to get the count.
int i = (int)cmd1.ExecuteScalar();
|
|
|
|
|
How exactly do you reckon this will return the row count?
What is cmd1.CommandText in this case?

I have finished building an desktop application that is similar to Yahoo Messenger.
It has a client side and a server side and it is built using System.Runtime.Remoting
and uses a Singleton model.
I have registered a channel on the client side and on the server side like this:
ChannelServices.RegisterChannel(channel,false);
...
MarshalByRefObject obj = (MarshalByRefObject)RemotingServices.Connect(typeof(IServer),
"http://"+hostIP+":8980/Server");
Global.server=obj as IServer;
(obj as RemotingClientProxy).Timeout=5000;
where hostIP an IP address of the server location.
Until now I have used only 127.0.0.1 (localhost) for the server , but when I change the value to
my IP address, I get the following error:
{"Unable to connect to the remote server"} System.Exception {System.Net.WebException}
with the message :
"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond"
Does anyone knows how to solve this issue? Should I configure in some way the server(my computer) ?
Please help me .
Thanks in advance!

Your firewall is probably on. Open port 8980 for the interface on which you are trying to connect.
|
|
|
|
|
I have turned off my firewall and I don't get any error but now it doesn't connect at runtime with the server.
Do you have any other ideas I could try?

Not really 
Is this your pc's IP address, or the IP address of your Internet router? If it's your router, you'll have to set up port forwarding on the router.
|
|
|
|
|
I think is the IP of the router ...
Could you give me an idea about how should set up this port ?
Thanks for your reply !
|

Your should read your routers documentation for that.
The general principle is that an incoming connection on your router's ip is forwarded to a pc on your network, so in your case you should forward port 8980 on the routers external interface to port 8980 on your pc (giving the ip address of the pc)

Hello,
When i put this command in cmd console, its work, the file config.ini conatins the parameters of connection to the ftp file, how i can excute this command in c#, thank you.
|
|
|
|
|
is it ftp.exe or config.ini that isn't found? try changing one or the other and compare results.
is the folder containing ftp.exe part of your PATH environment variable? why don't you use an absolute path here?
|
|

Thank you for your answer, i use command ftp of windows, it was not an exe, in console CMD, i succed to excute the same command, but in c# it don't work, help to resolve thise great problem, thank you verry mutch.

use C:\Windows\System32\ftp.exe in your Process statement, rather than just ftp.
It is a real exe, there is no built-in ftp command!
