I believe those are registered "COM" DLL's which can be referred.
|

|
|

Navaneeth is right, The registered COM dlls. And you can register your dll usingn regsvr32, If it is a com dll.

Try this,
<asp:textbox runat="SERVER" onClick="this.value='';"/>
The main thing is the inline javascript in the onClick event.

Than you add the SqlParameter[] as addRange to the SqlConnection
Small Example?
SqlParameter[] parms = new SqlParameter[1];
parms[0] = new SqlParameter("@databaseID", dropDownList1.SelectedValue);
ddlDropDownlist2 = MyClass.FillMyDropDownList(ddlDropDownlist2, parms, "ddlText", "ddlID", "ConnectionString", "SqlCommandOrStoredProcedure");
public DropDownList FillMyDropDown(DropDownList ddlName, SqlParameter[] parms, String TextValue, String IDValue, String ConnectionName, String StoredProcedure)
{
SqlCommand cmd = null;
cmd = BaseDatabaseData(StoredProcedure, parms, ConnectionName);
ddlName.DataSource = cmd.ExecuteReader(CommandBehavior.CloseConnection);
ddlName.DataTextField = TextValue;
ddlName.DataValueField = IDValue;
ddlName.DataBind()
cmd.Connection.Close();
return ddlName;
}
private SqlCommand BaseDatabaseData(String StoredProc, SqlParameter[] arrParameters, String ConnectionName)
{
try
{
String connection = System.Configuration.ConfigurationManager.ConnectionStrings[ConnectionName].ConnectionString;
SqlConnection con = new SqlConnection(connection);
SqlCommand cmd = new SqlCommand(StoredProc, con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddRange(arrParameters);
cmd.CommandTimeout = 3600;
cmd.UpdatedRowSource = UpdateRowSource.None;
if (cmd.Connection.State.Equals(ConnectionState.Open))
cmd.Connection.Close();
cmd.Connection.Open();
return cmd;
}
catch (Exception err)
{
throw new Exception(err.Message, err.InnerException);
}
}

I am developing a web application using ASP.NET 2.0. I want to view/modify file metadata like Author, Title, Company, etc. that file may be a txt / doc / exe / xml / html / pdf/ doc any format...
File metadata can be viewed / modified using dsofile.dll, but it is applied only on Office documents.
How can I view/modify file metadata that can applied on all files( txt / doc / exe / xml / html / pdf).

Hi,
I've made a Web Crawler in C#.Net and it crawls a given url in the textbox for all the url's on the page and stores in database.
Then taking one url at a time it again crawls all the urls for email addresses on the contact page of the website.
Now what i want is that when i open my web browser and open google.com search for anything and the results which come out, i mean it gives all the links n urls so i want my tool to work there.
I want my web crawler to work with the google.com results... right now i'm manually providing one url in the textbox for the whole crawling procedures.
I hope i can get good advice and suggestion to solve my problem.
Thanks
