Hi,
that is no surprise, each control that gets redrawn by default starts of with clearing
the background, then painting the foreground.
There is an easy way to make this invisible, it is known as "double buffering" (which
means the drawing is made first in an off-screen buffer, then that one is copied over
the relevant part of the screen). There is Control.DoubleBuffered starting .NET 2.0;
for .NET 1.x you can achieve the same effect using SetStyles on an inherited Control.
Lots of articles on CP use these techniques.

Are you using Visual Studio 2003 or .Net 1.1?

Why "or"?

You could be using any number of methods for writing code, from notepad - sharpdevelop VS etc. My question was if it is .Net 1.1 or not.

Hmmmm????

Actually you where asking if he uses "Visual Studio 2003 or .Net 1.1".
He could also use SharpDevelop with .Net1.1!

Correct but you could just as easily be using just the SDK and the C# compiler with a text editor
|
|

Make sure you have put showdialog for you form popup on the combo box item changed event. if so, do you see any flickring on the form or you don't see any control on your form? if flickring is there, enable double buffering.

Sirr/Madam,
Is it right to say that the internal and internal protected access modifiers are accessible in the private assembly.
Thanks and Regards

You are correct that internal means that it is accessible in the pribate assembly. The prodtected access modifier means that it is accessible within its class and by derived classes. Here is an example for Protected from Microsoft help:
using System;
class A
{
protected int x = 123;
}
class B : A
{
static void Main()
{
A a = new A();
B b = new B();
// Error CS1540, because x can only be accessed by
// classes derived from A.
// a.x = 10;
// OK, because this class derives from A.
b.x = 10;
}
}
Hope that helps.
Ben

I have been trying to change color of tab control. But all i could do is change the color of tab - pages present on the tab control. It looks very awkward that tab pages of different color and the panel on which these pages are present is default color. Please if any one knows how to change the color of the tab control...

I have declared object in C#. And I want to use a method(logon) for that object in the next statement. Is there any way in C# to do like that. If I try to use it shows "Object does not contain definition for this method". I have tried in VB.net. It is working fine.

MyClass obj = new MyClass();
obj.Method(param);
if this doesn't help then show us the code...
life is study!!!

object objsession = Glue.newInstance("ClassName")
when this method is executed, it creates an object objsession. But there is a method called logon after the session is created.
objsession.logon(username,password)
This doesnot work. But in VB.net it works. Is there any solution?
|
|
|
|
|
C# is case sensative. Make sure logon is Logon when the method had capital letters.

One more thing how can get the messaged send by sql server when running quefries like 0 rows affected or any other message

1. some code would be usefull in finding the problem.
2. the sql command object's ExecuteNonQuery returns an int that is the number of rows affected.

What exactly does that mean? What do you want to do when a link button is clicked? It would help if you show some code.
