You should only ask the solution of your problem instead of copy pasting your code.
it's too long and i think nobody have enough time to go through it..
take it positively.
anyways what i guessed from your message's "subject" not from text, is that u want to access control from different thread than from in which it is contained or created.
so the solution is that (if u r working in c# 2.0)
write this line in constructor of the class where the control is
Control.CheckForIllegalCrossThreadCalls = false;

of browser window and drags /moves it browser also moves with it too, which i want to disable.how could
i acheive it please send some clue.if possible please send some code.

Your question doesn't really make sense to me. When you say that you have "created a browser", what do you mean exactly? What is "browser" in this context, and why should it not move when you move the window?

Hi all
"The located assembly's manifest definition with name 'Interop.SQLDMO' does not match the assembly reference."
That is the error I'm getting when I try to use a C# library with my application.
The thing is I am using SQLDMO in my app that calls the library and it is just fine - when I get to calling the DLL though I always get that error.
Could you please help me out from this. It is very urgent for me to resolve this problem.
Thanks in advance

hi,
is it possible to add a member variable/function to a class at runtime..
This is possible in Python..

C# is a statically typed language, which means that the compiler needs to know about all members of a class during compilation, so that it can lay them out properly in memory.
You can add static methods to a class using LCG[^], a new feature in .NET 2.0
|
|
|
|
|
No, that is not possible in .NET.
What are you trying to accomplish? For questions like this there usually is an object oriented solution that works just as well, or simetimes even better.

Can't we achieve this using CodeDOM?
|
|
|
|
|
No. You can use CodeDom to create source code, which you can compile if you want, but that can only be used to create a new assembly, you can't change an existing class at runtime.

hi,
i am developing a windows application in that i want to extract all the email ids present in the body of a particular text file
any idea
jaz
|
|
|
|
|
1- Crate a regular expression for email.
2- Read each sentence of the text one by one.
3 -Match it with the regular expression, if matched successfully store it somewhere [Like array list].
4- When you will complete reading the text file, you will be having all the email ids with you.

I am just a beginner in C# and need to create a basic C# form to enter student information:
first and last name
email
graduation year
month of graduation
I have to use some type of menu for the graduation year and month (dropdown, radio button list or checkbox list).
I have used C# code generator to create the following code:
using System;
namespace SIU.Student.Graduation
{
public class EntryForm
{
// private members
string strFirstName;
string strLastName;
string strEMail;
string strGraduationYear;
string strGraduationMonth;
// empty constructor
public EntryForm ()
{
}
// full constructor
public EntryForm (string FirstName, string LastName, string EMail, string GraduationYear, string GraduationMonth)
{
this.strFirstName = FirstName;
this.strLastName = LastName;
this.strEMail = EMail;
this.strGraduationYear = GraduationYear;
this.strGraduationMonth = GraduationMonth;
}
// public accessors
public string FirstName
{
get { return strFirstName;}
set { strFirstName = value; }
}
public string LastName
{
get { return strLastName;}
set { strLastName = value; }
}
public string EMail
{
get { return strEMail;}
set { strEMail = value; }
}
public string GraduationYear
{
get { return strGraduationYear;}
set { strGraduationYear = value; }
}
public string GraduationMonth
{
get { return strGraduationMonth;}
set { strGraduationMonth = value; }
}
}
}
using System;
using System.Data;
using System.Data.Client;
namespace SIU.Student.Graduation.Data
{
public class SqlDataProvider
{
public SqlDataProvider(){}
public void AddEntryForm(EntryForm EntryForm)
{
// Initialize SPROC
SqlConnection conn = new SqlConnection(Globals.ConnectionString);
SqlCommand cmd = new SqlCommand("KSU.Student.Graduation_EntryForm_Add", conn);
cmd.CommandType = CommandType.StoredProcedure;
// Add Parameters
cmd.Parameters.Add("@firstName", EntryForm.FirstName);
cmd.Parameters.Add("@lastName", EntryForm.LastName);
cmd.Parameters.Add("@eMail", EntryForm.EMail);
cmd.Parameters.Add("@graduationYear", EntryForm.GraduationYear);
cmd.Parameters.Add("@graduationMonth", EntryForm.GraduationMonth);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
}
public void UpdateEntryForm(EntryForm EntryForm)
{
// Initialize SPROC
SqlConnection conn = new SqlConnection(Globals.ConnectionString);
SqlCommand cmd = new SqlCommand("KSU.Student.Graduation_EntryForm_Update", conn);
cmd.CommandType = CommandType.StoredProcedure;
// Update Parameters
cmd.Parameters.Add("@firstName", EntryForm.FirstName);
cmd.Parameters.Add("@lastName", EntryForm.LastName);
cmd.Parameters.Add("@eMail", EntryForm.EMail);
cmd.Parameters.Add("@graduationYear", EntryForm.GraduationYear);
cmd.Parameters.Add("@graduationMonth", EntryForm.GraduationMonth);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
}
public void DeleteEntryForm(EntryForm EntryFormID)
{
// Initialize SPROC
SqlConnection conn = new SqlConnection(Globals.ConnectionString);
SqlCommand cmd = new SqlCommand("KSU.Student.Graduation_EntryForm_Delete", conn);
cmd.CommandType = CommandType.StoredProcedure;
// Delete Parameters
cmd.Parameters.Add("@EntryFormID", EntryFormID);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
}
public EntryForm GetEntryFormByID(EntryForm EntryFormID)
{
// Initialize SPROC
SqlConnection conn = new SqlConnection(Globals.ConnectionString);
SqlCommand cmd = new SqlCommand("KSU.Student.Graduation_EntryForm_GetByID", conn);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataReader reader = null;
EntryForm entryForm = null;
// GetByID Parameters
cmd.Parameters.Add("@EntryFormID", EntryFormID);
// Execute
conn.Open();
reader = cmd.ExecuteReader(CommandBehavior.CloseConnection);
if(reader.Read())
{
entryForm = SqlDataHelpers.PopulateEntryFormFromSqlDataReader(reader);
}
conn.Close();
return entryForm;
}
public static EntryForm PopulateEntryFormFromSqlDataReader(SqlDataReader dr)
{
EntryForm entryForm = new EntryForm();
entryForm.FirstName = Convert.ToString(dr["firstName"]);
entryForm.LastName = Convert.ToString(dr["lastName"]);
entryForm.EMail = Convert.ToString(dr["eMail"]);
entryForm.GraduationYear = Convert.ToString(dr["graduationYear"]);
entryForm.GraduationMonth = Convert.ToString(dr["graduationMonth"]);
return entryForm;
}
}
}
I need to figure out way to code the drop-down menu for GraduationYear and GraduationMonth fields.
Can somebody provide a ready code snippet to insert it in the above code pls?
Do I miss any other important coding for this entry form?
Thanks so much!

Hi,
Im trying to do a simple XML Record Lookup using the following code:
string fileName = "Account_Data.xml";<br />
XPathDocument doc = new XPathDocument(fileName);<br />
XPathNavigator nav = doc.CreateNavigator();<br />
<br />
XPathExpression expr;<br />
expr = nav.Compile("/Accounts/Account[FirstName='" + nameTextBox.Text + "']");<br />
XPathNodeIterator iterator = nav.Select(expr);<br />
iterator = nav.Select(expr);<br />
<br />
if (iterator.MoveNext())<br />
{<br />
<br />
<br />
}<br />
else<br />
{<br />
<br />
<br />
}
It works just fine, but there seem to be a minor bug with it. In the XML file, i already have a record with <firstname>Latheesan, so when i searched using my search form for "latheesan", it returned 0 results, hense it created a new record.
How can i avoid case sensitiveness issues with searching through XML Records?
|

Never done this myself, but I think you can only avoid case sensitiveness by turning both the search string as well as the content of FirstName to either upper or lower case. For the search string you can use the appropriate methods provided by the String class. In case of the content of FirstName you'll have to use XPath functions[^].

Hi, can anyone please enlighten me on how to create dynamic objects with different names during run time?
Thanks =)

Unclear question but that might be the answer
Object obj = System.Activator.CreateInstance()
