I would find the article interesting. I was looking at this kind of thing about 1.5 years ago, but with no time, I bought third party. I am especially interested in cross-browser support aspects, even though you haven't finished that part completely. What were the most difficult cross-browser compromises...stuff like that.

Your help is very appreciated.
I need to invoke browser and open the reference by (for exapmple) pressing the button in WIN32 aplication.
How I can do it?

How do you add/save a row using the INSERT sql command in a web form with textbox not a datagrid? Below is my code, what wroung and why does fall through to the "finally block?"
private void SaveRecord()
{
string strSQL;
if(btnSave.CommandArgument == "Add")
{
strSQL =
"INSERT INTO CoinCollection " +
" (ID, TypeOfCoin, YearOfCoin, StateOfCoin, DateReceive)" +
"VALUES " +
" (@ID, @TypeOfCoin, @YearOfCoin, @StateOfCoin, @DateReceive)";
}
else
{
// The user is updating an existing item
strSQL =
"UPDATE CoinCollection " +
" SET TypeOfCoin = @TypeOfCoin, " +
" YearOfCoin = @YearOfCoin, " +
" StateOfCoin = @StateOfCoin, " +
" DateReceive = @DateReceive " +
"WHERE ID = @ID";
}
SqlConnection conn = new SqlConnection(ConfigurationSettings.AppSettings["connString"]);
SqlCommand cmSQL = new SqlCommand(strSQL, conn);
// Add all the requuired SQL Parmeters.
cmSQL.Parameters.Add(new SqlParameter("@ID", SqlDbType.Int)).Value = Convert.ToInt32(tbID.Text);
cmSQL.Parameters.Add(new SqlParameter("@TypeOfCoin", SqlDbType.VarChar, 50)).Value = tbToc.Text;
cmSQL.Parameters.Add(new SqlParameter("@YearOfCoin", SqlDbType.VarChar, 50)).Value = tbYoc.Text;
cmSQL.Parameters.Add(new SqlParameter("@StateOfCoin", SqlDbType.VarChar, 50)).Value = tbSoc.Text;
cmSQL.Parameters.Add(new SqlParameter("@DateReceive", SqlDbType.VarChar, 50)).Value = tbDr.Text;
try
{
conn.Open();
cmSQL.ExecuteNonQuery();
strMsg = "Coin successfully saved to the database.";
}
catch(Exception exp)
{
strErrorMsg = "Database error! Coins not saved to database. Error Message: " + exp.Message;
}
finally
{
conn.Close();
btnAdd.Enabled = true;
}
}

Good morning and thanks for looking at this for me. The answer to your question is "no" the program drops through the exceptions to the finally block and executes the code to enable the Add button.

hi,
i need to access different servers providing same web service interface. when i want to access them i need to create two different web references.
when i access each of them i create instance of the webservice link and invoke a method.
i need to parse the 'return' object that i get it when i invoke a web service. the problem is i need to parse it separately the returns from two different webservices because of classCast problem.
most probably i am doing something wrong. how do i update my code so that i have common parsing and invocation methods for both of these services with same web service interface.
regards,
rnv

Hi there,
We have a web application written in asp.net (1.1). Without going
into too much detail, we use a DLL to communicate with the database and
also a couple of webservices. When we deployed version 1, everything
deployed OK on our webserver. We deployed the application and 1 webservice
under default web site, the other webservice (3rd party supplied) is on
another server and services many other application in our organisation
sucessfully.
Recently we have tried to deploy version 2, but this time we have assigned
another IP address to the web server and tried to install the application
under a new website. Everything looked OK the application installed OK and
most of the functionallity works just fine but 1 or 2 of the webservice calls
fails with the error:
"Index was outside the bounds of the array"
I get this error on both webservices, on specific webmethods, but it DOES
work OK on default website....
Any help on this would be appreciated

The error message is not at all specific for web services. The error is plainly as the message says; somewhere there is an array, and an attempt is made to access an item at an index that is outside the bounds of the array.
Does the error message come from the code calling the wbe service, or does the error message come from the code executed in the web service?

Hi there,
Thanks for your interest.
It looks like the web service returns no data and the calling code is falling over when populating a grid. As I have stated earlier, the code runs fine from 'default' website.

You have to specify for what class you want to call the ValueOf method.
cust_dob = Date.valueOf(year + "-" + month + "-" + day);

When a user clicks on a download button, it should popup an window asking for the type of file(it may contain dropdown list with list of values populated from a database). Based on the selection, the corresponding file format to be downloaded. How to incorporate the same in ASP.Net and how to invoke a message box like a normal application and also how to capture the command button clicked on the dialog box?
Thanks in advance
|

As the dialog should be displayed on the client side, you can't use ASP.NET to do it. The ASP.NET code is run on the server, using a dialog box would display it on the server, not on the client.
You have to use javascript to open a window with a page that let's the user do the selection.

The first page opens in about four seconds, the second in about 20 seconds.
I'm sitting in Sweden on a broadband connection (10 mbit/s).
