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.

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.

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).

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.

Remoting - test if Proxy/channel alive?

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.

The need to optimize rises from a bad design.My articles[^]

hmm, what does this mean (0.4, 0.2, 0.4)? Is this a tupel or an array?

It's not a bug, it's a feature!

If it is an array then you should define it like this:

<br />
double[] aValues = new double[3] { 0.4, 0.2, 0.1 };<br />

It's not a bug, it's a feature!

b= { 0.4, 0.2, 0.1 };
c= {0.2,0.5,0.3};

double[] b = new double[3] { 0.4, 0.2, 0.1 };

double[,] da = {{0.4, 0.2, 0.1}, {0.5, 0.2, 0.6}};

Access like so:

da[0, 1] = 0.2
da[1, 2] = 0.6

note: each array must have the same depth, although these can be default values if you do not wish to use them.

Or use jagged arrays

double[][] da = new double [][]{ 
  new double [] {0.6, 0.4},
  new double [] {0.4, 0.2, 0.1},
  new double [] {0.5, 0.2, 0.6}};
