If you check out the client applications config file, there should already be a webreference url entry. Before deploying the applicaiton to the client, cant you just change this entry to the right URL?

Unless I understood your query wrong

NameValueCollection.GetValues(string Key)

Hi,

When i use this NVC.GetValues(KeyName), at times i am getting the following

error,

Void Copy(System.Array, Int32, System.Array, Int32, Int32, Boolean) :

Source array was not long enough. Check srcIndex and length, and the array's
lower bounds.

and

i am getting NullReferenceException when i use NVC.AllKeys with the
following message,

System.String BaseGetKey(Int32) ~ NRE ~ Object reference not set to an
instance of an object.

I cant predict the reason.

Here is my code snippet,

public void ProcessData(MyNVC procNVC)
{
if (procNVC.Count > 0)
{
try
{

string[] KeyArray = procNVC.AllKeys;

foreach (string skey in KeyArray)
{
string[] sVals = procNVC.GetValues(skey);
if (sVals.Length > 0)
{
sbuild.Append(skey + procNVC.Sum(sVals) + ';');
}
}
}
catch (ArgumentException oARG)
{
log.Info(oARG.TargetSite + " ~ ARG ~ " + oARG.Message);
}
catch (NullReferenceException oNRE)
{
log.Info(oNRE.TargetSite.ToString() + " ~ NRE ~ " + oNRE.Message);
}
catch (Exception oEXcpn)
{
log.Info(oEXcpn.StackTrace + " ~ EXCPn ~ " + oEXcpn.Message);
}

if (sbuild.Length > 0)
{
SendToClient(sbuild.ToString());
sbuild.Remove(0, sbuild.Length);
}
}
else
log.Info("No Elements in Collection:" );
}

With Thanks and Regards
Sakthi.

Hi,thanks for the quick response
Am using windows forms no ASP.NET.

to load the current row selected in the datagridview

int CustomerID = int.Parse(dataGridView1[dataGridView1.CurrentCellAddress.Y, 0].ToString());
customer customer = customerManager.GetCustomer(customerID);

then i fill the respective textboxes with data from that cell

txtcustomerID.Text = customer.CustomerID.ToString();
txtname.Text = customer.CompanyName;

the GetCustomer() method's definition is

public static customer GetCustomer(System.Int32 CustomerID)
{
string ConnectionString = "Server = (local);Integrated Security = SSPI ;Initial Catalog = pos";
string query = "Select * from CompanyProfile where CustomerId " + CustomerID;

DataTable dt = DataManager.ExecuteQuery(ConnectionString, query, "customer");
if (dt.Rows.Count == 0)
{
return null;
}
return new customer(dt.Rows[0]);
}

But when i run the Program and click in one of the cells,I get an error saying Input string is not in the correct format.
and the customerID value is 0 in that case though the value in the Database is 1.

What i want to do is,Get the value of the first cell with index 0 of the column CustomerID and use it in the query
which is "select * from companyprofile where customerID " +CustomerID;

Hello,

You could work with timers. (System.Windows.Forms.Timer)

Or use Thread.Sleep(1000)

All the best,

Hi,

How can you find the process that called a particular function?

I've set a breakpoint on a function that gets called twice but should only be called once. I don't really want to step through the whole program so how do I know what executed immediately prior to the breakpoint?

That's what the Call Stack window in VS is there for. Smile | :)

Place a breakpoint in your method and then bring up the Call Stack window (you will find it in the lower right of the VS window when you're debugging) - it will show you everything from Main().

1-Jul-07 19:22

Hai Everybody,

Have a good day and great month

I have created an sample application in that, I kept a remotable object, I am having listener and client which are all windows services.

I have included the remotable object's reference in both clien and host application.

When i tried to build it has been done successfully.
but when i tried to compile the Server_Service class it is showing warnings like are you missing the assembly for all the namespaces that i have included in the service class even though for the System namespace also it is showing this error.

Can anyone give me a solution to solve this, Please....

You will give me the solution so Smile | :)

I have all the references in the project. And all the three projects( Remotable object, Server_Service and Client_Service) are all in the same solution.

Are you trying to reserve space for a string, a la C/C++? You don't need to do that in C# as the string is a first class citizen in .NET. Just say string s = null; and then you can assign any value you want, like s = "I love Bob";
