i send the RTF of the richtextbox,
but when i receive the message and try to append the received string to the rtf of the richtextbox by richtextbox1.Rtf += receivedMsg;
here receivedMsg is the rtf that the client has sent.
but the above line does not append the message to the richtextbox.
Thanks,
Pramod

Do not do like this.
Make sure caret are at the end of RTxtBox. & use
richtextbox1.SelectedRtf = receivedMsg;
It will insert text where the caret is.

hi frnds, i m creating a project in visual studio 2005 at home. but in my college vs2003 is installed, so please tell me the way how to open that project in college...
|
|
|
|

I don`t know if that is posible because VS 2005 has a different way of managing source files within the project. For an example in VS 2005 if you add a new form to the project, it will be represented by to files, one containig your code and one containing autogenerated code like filed init and stuff like that. However in VS 2003 all the code was in a single file.

It is not possible. You cannot open a newer version of solution using an old version fo Visual Studio.
The only way you can do is create a new solution under VS2003 and add each file *.cs, *.resx, ... to this solution.
That's why, you must write your code as clean as possible. That means you can use your code in VS2003 and VS2005. Without something specific from VS2005.

i save my application settings in a settings.xml file. The settings.xml is editable with any text editor and therefore i always have to consider the fact the settings could ha been mnaullly edited. Is there a way io could encode or something my settings.xml so that the user cant see the the actual content. Also, how can i check wether my file has been modified.

I think you can create a hash for your file and put it at the beginning.
Then the next time you want to load that file, you must first create
a hash from it and compare it with the hash in you XML file. If it is the
same, then your file is not editted. Otherwise, someone has edit your file.
Use MD5ServiceCryptoProvider.

Iam working on MDI application and I have some problem.
For the main form, IsMdiContainer is set to true as well as the MdiParent for child form, is set to 'this' (main form).
But problem starts here.
I put all the codes for each controls in each separete class so it's easy to manipulate.
In Tabs class, I have all the methods, properties I need for adding, removing, renaming etc. tabs.
I also have a method for adding new child forms.
In this method, MdiParent isn't set to 'this', but to frmMain.ActiveForm.
The thing is that everything works great unless I try to add new tab from the other Form.
App then breaks at line MdiParent = frmMain.ActiveForm with this error:
Form that was specified to be the MdiParent for this form is not an MdiContainer.<br />
Parameter name: value.
How can I workaround this problem, but still have this method for adding new child forms in Tabs class?
Iam out of ideas.
Sorry if my post is confusing.

Hi,
ActiveForm is a static property of the Form class that returns currently activated form for the application but not the acitve frmMain instance. So in some cases you try to bind child form to the non-MDI-parent form.
To have access to your frmMain form from all your classes you can add static property to it (as in the Singleton pattern):
class frmMain
{
private static frmMain current;
public static frmMain Current
{
get
{
return current;
}
}
public frmMain()
{
current = this;
}
}
Then you can use this property to construct your MDI-child forms:
childForm.MDIParent = frmMain.Current;

Thank you Andrew, very much. It works like a clock.
I've tried something similar, but mine wouldn't work  .
I've used other class for this, and it happened nothing, no error, no action, no anything .
And again, thanks.

I chceked - debugger show this line of code is called in BackgroundWorker thread - but how it work in "normal" mode?

i think the same problem was with ma project,,,
i think we cannot run two prosess in 1 thread..(ie listening and connecting)
this will cause Cross-Thread exception...
so just create the setup and run the exe file.
