Hello,
I am doing remote desktop application. In that from client to server connection is made in web but from server, it is not passing any data to client. I have make port forwarding in router.
My router is Pronet PN-54WRT. In virtual server list i have made port as 5001.
Please any one help me out.
Thank you in advance.

I dont think that its a Router problem. If you can connect to the server and server is not transfering the data, then its a different problem. but in all the cases you have to change settings on server. make sure that the port is open on server. if you have hosted your application on third party web hosting then most of them will not support any TCP/UDP Port to be open.

Thank you for reply me,
I have used http channel for transmission and 5001 port is used. How can i check whether my port is open or not, and when server is receiving data on the same port then it can send data also.
But i dont know what the exact problem is i have tested on localhost and it works fine.
Is there any other issue?
Help me.
Thank you.

OK change your port to different number other then 5001. 5001 is known port for virus so it is generally blocked by firewall/antivirus.
and try the following
netstat -ano
command in DOS Command Prompt to get a list of Already Used Ports so that you can use free ports. you can also get the information about connection status. so try to run the command on server, if you have access.
Also try to post the Error Messege which you get. Are you able to make connection to the server ? Have hosted your application on 3rd party server ?

Youre not using the LAN ip are you?
|
|
|
|
|
Thank you for reply me,
I am using router ip that is static.
And in router configuration menu i have assign ipaddress as local ip assigned by the router i.e. 192.168.1.108.
Thank you.

Well there you go, if you are access the client / server from outside your lan and however you are connecting is using that IP, then you won't get anywhere. You have to use its exposed IP, the LAN is hidden to machines only within the network.

Thank you,
Sorry but i am not getting you.
I have used router ip to connect to server.
And in server's router config. I have used server's wireless ip add.
Help me.
Thank you.

I am helping you, you are using the wrong IP, use the IPs that are given to you when either machine goes to http://www.whatismyip.com
You are using the LAN ip, which is constricted to the LAN (Local Area Network). You are using your program OUTSIDE of the LOCAL AREA NETWORK so you can't use that ip.
Can't get clearer then that.

Thank you,
Sorry but you getting me wrong, I am using the same address in my application as you have send link for getting ip address.
And i am already connected with server.
|
|
|
|

Ok. It looks like youe server response is not reaching client. Are you inside the Proxy Network ?
Proxy Server will send the IP address of itself instead of your client node. so server will reply to that address instead of your PC.
Have you tried the client application from outside your company LAN ? like from your home or computer which is directly connected to internet (not thru your company LAN).

Thank you for reply me,
I am outside the proxy network, client is installed at home and server is installed on company network.

how to clear all the rows from datagridview.
tbhattacharjee
|
|
|
|
|
It should be datagridview.Rows.Clear()
Please go through the documentation before asking such questions.

I just ran into this problem too. If you are binding your DataGridView to a data object such as a DataTable:
dvBalances.DataSource = _table
When you want to clear the rows in the DataViewGrid do this:
_table.Clear()
Something like:
dvBalances.Rows.Clear()
won't work.

hello
On client side:
<br />
oRemoteObj = (RemoteObj)Activator.GetObject(typeof(RemoteObj), strUrl);<br />
Apart from actually invoking method on "oRemoteObj", is there any convenient way to test if the proxy/channel is still alive?
Thanks

Instead of reading the data from the cells, I think you should read the data from the underlying datasource (datatable for example). Special columns like combobox column, image column etc. act each a bit differently and there is no extra cell for the data in those columns.
