private void textBox1_KeyDown(object sender, KeyEventArgs e) {
if(e.Control && e.KeyCode == Keys.C) {
e.SuppressKeyPress = true;
}
else if(e.Control && e.KeyCode == Keys.V) {
e.SuppressKeyPress = true;
}
}
this is good, but i do't want to this code paste in all control.
i want this code type only one time

Do you mean you want this code to execute only once?
If yes then just unbind it using
this.textBox1.KeyDown -= new KeyEventHandler(this.textBox1_KeyDown);

Aside from the fact he probably shouldn't have just posted up this code as an instant solution (requiring the OP to do nothing for himself), the code only needs to be written once, you can bind one event to multiple controls.

What if the user copies or pasties using context menu of the textbox?

Just reinitialize the context menu of the textbox during form load without any items in it.

I actually found a bug, where you can still get the context menu even when you do that.
If i remember right, to get the context menu to STILL appear, you right-click the text box and hold the button down - move you mouse off of the text box - and then release the button. Then the normal menu appears

hello,
I have an application that allow me to create many Forms.
When i open many forms i get this error : Error creating windows handle.
After i check for this kind of error, there is many suggestion to minimize the number of controls(handles) because each process do suppport a specified number of controls.
but my forms contain a user controls and more thing that i can't remove.
Do someone have any idea fr this kind of error.
Best regards,

Hard to make sense of this. How many windows do you have open ?

Well, that is just a nightmare for the end user, but I don't see why Windows can't handle it.

error :
Error creating windows handle win32Exception
i think because the number of handle exceed a specifiv limit .
What to do ?

Hey guys...
in my application all my forms inherit from cmdBaseClass which inherits from Form so essentially i have
myForm : cmdBaseClass : Form
now what i want is so inherit cmdBaseClass from a plain class (not a form) but i dont want to inherit Form because this class is not a form
the only way i can think of doing this is creating a 2nd cmdBaseClass and not inherit Form from that one...
is there a better way to do this?
thanx

There's no two ways around this b/c C# sucks and does not have multiple inheritance. If you want to be able to use a form and non form as if they are the same with respect to a group of functions, you can use an interface, but you still need to define it twice.

dude,
i made a 2nd cmdBaseClass now (does not inherit Form)...
now my "GlobalMethodsClass" needs to inherit the "Non Form CmdBaseClass" but GlobalMethodsClass is STATIC... it moans that static classes should inherit from objects
i don't get it? isn't cmdBaseClass an object? i thought EVERYTHING in an OOP language is considered an object 
thanx

Two classes with the same name ?

If the class is static, then all your methods need to be static. I don't know if you can derive a static class from another.
Nope - static classes cannot have a base class. That does make sense, b/c what's the point of a class having a base, when no instances of that class can ever exist ?

OK - so your only problem is that one is static. Just don't make it static, it's just syntactic sugar anyhow, to force you to make all properties/methods static. You can still do that in a non static class.

Hello!
Is there any way to get the table's definition (SQL Server 2005) in C#?
Regards,
Adeel
Do rate the reply, if it helps or even if it doesnot, because it helps the members to know, what solved the issue. Thanks.

You can execute stored procedure "sp_tables" through code to get list of tables and "sp_columns @tablename" to get the name type etc of each column of a table.

Thanks for your reply, but i doubt if they are C# classes/libraries...!

These are stored procedures provided by SQL Server to get database and table schemas. You can run these using SQLCommand and read the out come using SQLDataReader class.
|
|
|
|

The Connection object provides you the "GetSchema()" method, which returns a DataTable filled with schema informations.
You have to specifiy what information you want in parameters of the method.
Example:
<br />
DataTable _indicesSchema = null;<br />
using (OleDbConnection connection = new OleDbConnection("Provider=SQLOLEDB;Password=******;Persist Security Info=True;User ID=sa;Initial Catalog=*****;Data Source=*******"))<br />
<br />
connection.Open();<br />
<br />
_indicesSchema = connection.GetSchema("Indexes", new string[] { null, null, null, null });<br />
<br />
connection.Close();<br />
<br />
}<br />
Hope was helpfull

Take a look at the GetSchema command on your connection object. It has all sorts of useful abilities for retrieving information about the database. I mention this one rather than directing you towards particular tables/stored procedures in the database because it gives you the option to discover information from lots of different database types.
