You will need to use either a UserControl or wrap the controls in a panel and insert the panel into the grid cell.

The security restrictions prevent this for good reason.

You don't! This would be a major security flaw if allowed which is why it is not.

Hi
I'm working on a teleprompter software (that flips a given text and lets the user to scroll it pixel by pixel)
I tried GDI+ using C# .Each time the user wants to scroll the text an image of the current lines is made.Then the image is rotated and loaded into a pciture box.
Unfortunately this procedure is very slow.
I like to ask if there is anyway that I can do the same thing using DirectX or OpenGL (I've already searched the ineternet but I couldn't find any answer)
Is there any other way that I can show the text upside down and let the user to scorll it?
Thanks a lot

Use a RotateTransform before drawing the text onto your Graphics object. You will need to do a TranslateTransform as well to get things where you expect them to be.

Hi
Thank you.
Actually I have tried it but the text blinks(The picture is painted every 10 milliseconds)
Here's what I did:
1.Get the graphics object.
2.Clear
3.RotateTransform
4.TranslateTransform
5.DrawText
6.Flush
7.Dispose
It seems that every time the clear method is called casues the text to blink
Is there anyway that I can make the movement of the text smoother ?
Thanks again.

You might need to apply double buffering to the form. That way it won't flicker.

Hi
How can I apply double buffering to the form ?
Thnaks
|
|
|
|
|
If your using .Net 2.0 theres a property on the form called 'DoubleBuffered', just set it to true.
|
|
|
|
|
Hello,
If you are using .Net 1.x, you have to use the SetStyle method of the Form class.
this.SetStyle(
ControlStyles.DoubleBuffer |
ControlStyles.AllPaintingInWmPaint |
ControlStyles.UserPaint |
ControlStyles.ResizeRedraw,
true);
In .Net 2.0 there is a new member of the ControlStyles enum which optimizes the perfomance of DoubleBuffering.
this.SetStyle(
ControlStyles.OptimizedDoubleBuffer |
ControlStyles.AllPaintingInWmPaint |
ControlStyles.UserPaint |
ControlStyles.ResizeRedraw,
true);
All the best,
Martin

true);
Thank you.

I'm developing a 'socket programming solution for client server architecture'. There a client connects to a server and send messages.
But i got this error,"cross thread operation not valid" and found a solution as follows.
It has to pass the thread address but i dont know how to obtain a thread address.
Could you please tell me how to obtain a thread address.
This is the solution i found.
----------------------------------------
Thread mythread = new Thread(addressOf thread1);
mythread.start();
Sub MyThread1
' Working code
' Working code
' Working code
' Working code
' Working code
' Working code
AccessControl();
End Sub
--------------------------------
Thank you.

It not the address of the thread, it is a delegate for the method to invoke when the thread begins execution. Check the documentation on MSDN. Here is a sample.
Public Class Test
<mtathread> _
Shared Sub Main()
Dim newThread As New Thread(AddressOf Work.DoWork)
newThread.Start()
End Sub
End Class
Public Class Work
Private Sub New()
End Sub
Shared Sub DoWork()
End Sub
End Class

Hi,
Thanx alot for your reply.

Hi
Actually you don't have to obtain the address of a thread instead you provide the name of a function (Your thread function) and .net will find the address for you . AddressOf is a VB.net keyword that returns the address of a callback function.In C# you don't have to use any keywords .
For example:
<br />
Thread myThread=new Thread(new ThreadStart(MyFunction));<br />
myThread.Start();<br />
That MyFunction is a call back function that will be called when the thread is started and the ThreadStart is a delegate to MyFunction.
Regards

I need to save the entire form in bmp format. I 've used the following code:
Bitmap bi = new Bitmap(this.Width, this.Height);
this.DrawToBitmap(bi,new Rectangle(0,0,this.Width,this.Height));
bi.Save (@"c:\Test.bmp", ImageFormat.Bmp);
Problem: only the visible area of the form is saving in bmp format. the other part like area of the form occupied by scroll bar is not saving.
could you please give me any suggestions.
