Like cadi said, you have to write a proxy application that checks for the existance of the .NET Framework, preferrably the correct version of it. Then it launches your application is the requirement is met.
The catch is, you can't use C#, J#, or any of the Managed languages to do this. It either has to be written in unmanaged C++ or some other language that doesn't need the .NET Framework to run.

client recieve bitmap data in thread from server.
when this data assigne to pictureBox from thread it is halt.

Very sparse information you give us. Please post some code the next time, or else helping you is subject to a lot of guessing 
Could it be that you're assigning the data from the wrong thread? Try using Invoke().

What mav has indirectly said is that you can't modify a control from a thread other than the one that created it. Since your picturebox is on the UI thread, the one your form was created on, you can't modify it from any other thread. It MUST be modified, including setting properties, by some code running on the Form thread.

My chat application uses UdpClient class. It is working fine on LAN as well as over the internet. I can not recieve messages in one senerio, when I send message over the internet and the receiving party is indirectly connected to the internet like using a shared internet connection over LAN. How do I reach those clients?
There is no server program and both parties are connected directly through IPs.

Your probably talking about the common situation where each machine is sitting behind a router/NAT/Firewall. In this case, your application doesn't do anything different. Each user must change the configuration of their NAT/Firewall to forward the port that your chat program is using to the machine's local IP address, usually on the 192.168.x.x network.

Thanks for the reply. Ok you got it right.. my client has a local IP address 192.168.x.x. How do I change the configuration of NAT to forward the port??

That's up to each individual router. You really can't do that in your code without writing a version for each manufacturer and different models of routers.

One thing more... Udp being connectionless, the client at the other end is just sending messages to the public IP. How does it know that the message has to be forwarded to the 192.168.0.34 ?? There has be to some information at the sending end that the message is for 192.168.0.34 (local) on 205.166.6.33 (public IP)
I am so confused 
|
|
|
|
|
Your actually sending to a specific port at an IP address, not just to the IP address alone. The router has a table that tells it where to forward individual ports to local IP addresses.

It would appear that you have code executing in your control's New or Initialize methods, or somewhere else for that matter, that calls itself recursively until the Stack is exhausted. You'll have to set a breakpoint in your code's New method and step through it line-by-line to see where the problem is.

How can we run a .NET web service on Apache server on Windows.
The .NET service is in J# and so Mono XSP seems not supporting this.
Help me if anyone know something regarding this.
Thanks in advance.

I have a windows form with several richtextboxes. I have created a button which fires the fontDialogue to change the style of the selected font.
When I select the text to be changed and then click the button to change the font style the richtextbox control loses focus. However the style still gets applied to the tex that was selected.
The problem I have is when changing the font style of text within another richtextbox the previously selected text from the first richtextbox changes also.
How can test to see which control has text selected?
Here is the button event trigger:
private void btnFontStyle_Click(object sender, System.EventArgs e)
{
if(this.fontDialog1.ShowDialog() == DialogResult.OK)
{
foreach(Control ctrl in this.pnlMain.Controls)
{
if(ctrl.GetType() == typeof(System.Windows.Forms.RichTextBox))
{
if (((System.Windows.Forms.RichTextBox)ctrl).Modified)
((System.Windows.Forms.RichTextBox)ctrl).SelectionFont = this.fontDialog1.Font;
}
}
}
}

It would appear that you have a design flaw in your application. Both RichTextBox's will maintain their own Selection's whether they have the focus or not. Since your code is interating through all the controls on the form and changing the RTB's that have been modified, your code is applying the new font to all the RTB's that have been modified, not the one that last had the focus!
If you insist on having multiple RTB's on the form that the user can edit and change the font on, you'll have to implement a flag on your form that holds a reference to the last RTB to have the focus. Handle the GotFocus event of all your RTB's and set this flag pointing to the one that got the focus. Then, in your button click event, you'll know which RTB had the focus last without having to iterate through all the controls on the form.

Thanks for the input. I was going to do that but thought it would be unecessary to have code for each control. Thought there might be a generic method I could use.
I appreciate your help

It is. You can have one handler function that handles the same event for mutiple controls. If you look in the "Windows Form Designer generated code" section, you'll see that things like the button click event get wired up with a statement like:
this.button1.Click += new System.EventHandler(this.button1_Click);
Well, if you have multiple buttons, you can point them all at one click handler if you need to handle all their clicks in the same code:
this.button1.Click += new System.EventHandler(this.button1_Click);
this.button2.Click += new System.EventHandler(this.button1_Click);
this.button3.Click += new System.EventHandler(this.button1_Click);
Notice, each one of these is an addition statement.

Just add a reference to System.Windows.Forms.dll to the project and you should be fine. (Right click on Project in Solution Explorer, click Add References, select System.Windows.Forms.dll in the listbox that comes up).

Thank you for your help. It works.
I have another question. In windows application I can write System.Console.WriteLine( "something" )
The program complies with no problems but the console never showup. Is there any solution?
Thank you
|
|
|
|

Are you sure you want a console to appear? Maybe you can make do with writing to the Trace?
In any case, the reverse of what you did the first time will solve your problem. Create a console application and copy/paste the form code in Main.

Senthil
