Hi,
have a look here:

It is a little bit old (e.g. using VS 2003), but the idea behind the article is still actual.

Combine the RichTextBox with a ContextMenu control, and do the methods of Cut, Copy, etc. in ContextMenu control? 
|
|
|
|
|
Thanks for your prompt reply.
Here my question suppose If I am having two RichTextBox and Shall I want to create two ContextMenu Control or I can use One and refer two Rich textbox. Please explain.
|
|
|
|
|
As d@nish said below, that is 100% possible. You just have to set the ContextMenuStrip Property for those two of your RichTextBoxes, enjoying the coding time.

There is a ContextMenu property for a RichTextBox. You can use that to add a context menu with whatever items you like.

I used SMO to manage SQL server 2005.
I want to modify a column to be same with other column.
I used the following code but it has error while calling Column.Alter() function.
<code>
public void RepairColumns(object dcolumn)
{
try
{
Column d_Column = (Column)dcolumn;
Column l_Column = mServer.Databases[mSMOInfo.DBName].Tables[mSMOInfo.TableIndex].Columns[mSMOInfo.ColumnIndex];
l_Column.Initialize(true);
l_Column.Collation = d_Column.Collation;
l_Column.Computed = d_Column.Computed;
l_Column.ComputedText = d_Column.ComputedText;
l_Column.DataType = d_Column.DataType;
l_Column.Default = d_Column.Default;
l_Column.Identity = d_Column.Identity; string str = d_Column.Properties[1].Name;
l_Column.IdentityIncrement = d_Column.IdentityIncrement;
l_Column.IdentitySeed = d_Column.IdentitySeed;
l_Column.NotForReplication = d_Column.NotForReplication;
l_Column.Nullable = d_Column.Nullable;
l_Column.RowGuidCol = d_Column.RowGuidCol;
l_Column.Rule = d_Column.Rule;
l_Column.RuleSchema = d_Column.RuleSchema;
l_Column.IsPersisted = d_Column.IsPersisted;
l_Column.DefaultSchema = d_Column.DefaultSchema;
l_Column.Alter();
}
catch (SmoException ex)
{
throw ex;
}
}
</code>
If u knows my mistakes, pls point me.
Thanks

Hi,
could you post the error message? This would help us to understand the problem a bit better.

I use adventurework database.
Error is
FailedOperationException - "Alter failed for Column 'SystemInformationID'."
InnerExcetpion - "Modifying the Computed property of the Column object is not allowed. You must drop and recreate the object with the desired property."
|
|
|
|
|
Setting the computed property does only work if you drop and add the column. (As the error message is saying):
http://www.windows-tech.info/15/83beeb9f84f9b78a.php[^]
Do you need to change the computed value of the column? If not, just leave the line
l_Column.Computed = d_Column.Computed;
out.

Thank for ur reply.
My goal is to change the column properties to be the same with other column.
I already left "Computed" property but an error has been occur with the other property of the column.

Well... Do you change any default settings of your database server... Can you alter any table in design mode....Let me know.

This is me opinion...for this purpose you can use a storedProcedure.

Hi
I have written a project in C#.Net 2005 that is connected to SQL Server 2000. The SQL Server Engine is on a server and there are three clients connecting to this server. The application is running on clients. Each minute many requests such as select, insert and ... are sent to the server, through transactions. The default timeout of the SQL Server has not been changed. After 200 requests, for example (the number is random, sometimes more, sometimes less), an error occurs which is:
"Timeout expired, the timeout period elapsed prior to the completion of the operation or the server is not responding"
With no changes in the server name, firewall, network protocol or whatever, the next request after this error, will be sent correctly and the response will be got correctly. Can anyone help me to solve this problem?
Thanks in advance

I Dont knoq much about MSSQL, i know more MySQL
Do the uses have high response rate to each query?
How many connection can connect to MSSQL simutanosly?
Do you use Windows XP as OS? (Profesional version has a limit to 10 connections. there are some patches to increase that number)

Is your application connected to the database server on Local / remote environment?
Thanks

Have you forgotten to close the DB connection when done, so the connection pool would get exhausted pretty soon?

I want to have a class name Faculty with some memeber properties. One of the property is a (list of student classes) List<myStudent>. I have a student class (as given below).
When I compile I get the following error:
"Inconsistent accessibility: parameter type 'NestedClass.myStudent' is less accessible than method 'NestedClass.myFacultyMember.AddMyNewItem"
What am I doing wrong?
Cannot we access user defined data types (in this case a class object) within a class from outside?
Thank you in advance!
------------student class-----------------------
<using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

{
private int studentID;
private string firstName;

private int age;
public myStudent()
{
}
~myStudent()
{
}
public int StudentID
{
get
{
return studentID;
}
set
{
studentID = value;
}
}
public string FirstName

myStudent class is private and myFacultyMember is public. You can't expose myStudent class as it is private. To resolve, make it public.

Hi,
I am trying to read the date from one file into another a new file.
(I know I could just copy it, but I will eventually be processing the data inbetween so I need to do it this way).
So first I create a StreamWriter with the existing path, then I create a StreamReader with the new path, and copy one to the other.
StreamWriter writer = new StreamWriter (existingFilePath);
StreamReader reader = new StreamReader(copiedFilePath);
string strData = reader.ReadToEnd();
Writer.Write(strData);
writer .Close();
reader.Close();
And the end result.... the new file is about 25mb but the old file was only 19mb.
Is this to do with the encoding? Its a PNG file I have selected but ultimatly it could be any file type.
I need to create an EXACT copy! Please help
James

That is not a string. There is no encoding, it's just raw binary data.
You could use File.ReadAllBytes, for example
