RichTextBox does have a SetStyle method (it is inherited from Control), but it is protected so only accessible from a derived class.

As was suggested above, to get the functionality you require you must inherit from RichTextBox, set the relevant style flags in your constructor and do your painting in the overriden OnPaint method. Im pretty sure you are using Graphics g = Graphics.CreateGraphics(yourRTBInstance) to draw, which in this case is the wrong way.

Hi Marc,

i got it and now the drawing is done fine but still some flickering
is there.

This has also caused one more problem\, Due to this code
now if i type something in the Richtextbox it does not shows the text
instead white spaces are shown

any suggestions to avoid this

Thanks

I have no experience with RichTextBoxes, only owner-drawn controls, so i dont think i can help you that much. You can try fiddling with the SetStyle flags.

base.Setstyle(ControlStyles.DoubleBuffer | ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint, true);

base.Setstyle(ControlStyles.DoubleBuffer, true);
or
base.Setstyle(ControlStyles.DoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);
or
base.Setstyle(ControlStyles.DoubleBuffer | ControlStyles.UserPaint, true);

Sorry i can't help you any further...

Did you try this?

public class MyRichText : RichTextBox
   {
       public MyRichText()
       {
           //by setting Double Buffer, the painting will finish before its redenered
           SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
           SetStyle(ControlStyles.ResizeRedraw, true);
           SetStyle(ControlStyles.Selectable, true);

       }
   }

Hi,
I had created setup files for the project which i worked on. So the user has to install the setup and run the application. The next time i give him the new setup of the same project, then he'll have to uninstall it from 'Control Pane->Add/Remove Programs'.
Is there a way by which he need not uninstall again and again i give him new setups, but just update it??
please can anyone just help me out here??

If you're using .Net 2.0, using ClickOnce makes updating applications easier.

Hi!
There's a setting somewhere in the setup project to "check for newer version". You'll also have to increment the version of your project or windows installer will tell you that this particular version is installed already.

You could use Process.Start() to excecute this command:

Socket Programming help

10-Jan-06 17:29

Can someone here help me to make and learn Socket programming?

I'm trying too make a program that can Control Port Flooding..When a port gets flooded the socket will Close the port, Establish a New Port (without loosing current connection)...

But not have the Flooding from external applications tag along to the New port that was just opened...

trying to solve a problem with some chat rooms on the internet due to Aka "Booter" Programs that send Packets of information to a persons ID/Username knocking them offline and loading down their computer with Pop up's etc..

Most Firewalls,Chat Clients ect dont really do a good job of being able to control this problem because of the fact that some of these programs will and do target " Back Door Ports" like 1024,1025 etc...

Thxs in Advance for any and all help!! Smile | :)
