Isn't there something on the standard right click menu which does that, for the method selected ?

Hi Chris,
U r right.. We can view the references of the methods on right click of them.

However I am in need of a tool that will take a class as input and give me the interdependancy of methods as the output.

Could u please suggest me on that?

Thanks in advance,
Murali

How about you write a program that does it?

I think Visual Studio has something called an Outline that will show all that. Not sure, I am almost sure there is something built into Visual Studio though.

Yes, that is one way to do it. I remember something that allowed you to see all the things you referenced, and then where all you did so.

Sir,
I am from VB6 background and new to C#.
I am making a desktop application using the C#.

I have two windows forms say Winfrm1 and Winfrm2.

on Winfrm1 i have a command button named Button1 and also a grid which holds the customer names from the database.
when i click onto the button1, Winfrm2 form shows in modal manner i.e. showDialogue.
On Winfrm2, I fill the data and save it, when i close the Winfrm2 I want to see the newely added customer on
Winfrm1's grid ...
for that i call the fillgrid method on Winfrm1's activated, enter event but unable to get desirable output
when click to the any control on Winfrm1 then enter event is called and this makes me in trouble .

In vb 6 activate event calls whenever form got focus for this what i should do in C#....?

Confused | :confused:

Use the forms OnClose event to call the updating code for the datagrid.

i would definately take a different approach.

in Winfrm2 create an event. called something like "DataSaved". you'll need to do this...

public delegate void DataSavedEventHandler(object sender, System.EventArgs e);<br />
public event DataSavedEventHandler DataSaved;

when you create an instance of Winfrm2 from within Winfrm1, you need to subscribe to the event with "+="...

Winfrm2.DataSaved += new DataSavedEventHandler(Winfrm2_DataSaved);<br />
private void Winfrm2_DataSaved(object sender, System.EventArgs e)<br />
{<br />
 //code to update screen...<br />
}

you then trigger the event whenever you add something in Winfrm2, by using something like...

if (this.DataSaved != null) this.DataSaved(this, new EventArgs());

What u need is using asynchronous invokes:
the problem u have is because of the GUI background multitasking:

the solution:

if(Button1.InvokeRequired == true)
{
Button1.Invoke(method1);
}

private void method1()
{
Thread Call to Method2
}

private void Method2()
{
// Here You need to show the form;P

}

Hi Devesh,
One of the easiest way is to use a common file between the applications.
The other way would be to use the config file and have some keys specific to each process.

To know if ur application is running, u can search for ur application name in the Processes list of the machine where u have to search at.

Murali

While developing ur application, in the app.config file, create a key (say 'instancenumber').

Then at runtime, set the key to a value (say '1','2',etc.) based on the instance of the application running.

This will enable you to associate information specific to each instance.

Hello,

Why don’t you want to use .Net Remoting. I think that this solution will be easy. Or you can use Global Shared Memory, but if you choose this solution, you’ll work with P/Invoke (DllImport).

Thanks in advance.
