I have one form with name HOME......which contains a link to CONNECT form...
And am having another form let it be CONNECT it contains a link....
The link navigate to HOME FORM....
but i want to do like this..if i click link in CONNECT form it must close the
previously opened HOME form and CONNECT form and i want open HOME form newely....
plz s****t me..
thanks,
Are you sure you want this kind of behaviour?
It's quite difficult to implement. Why? Because did you think where you are going to store the CONNECT forms variable which you instantiate in HOME form?
I will just show my code ...
in main form i.e., in HOME
same in CONNECT form also instead of creatinng connect object i created home object....Code:CONNECT cnt = new CONNECT();
cnt.show();
linklabel.LinkedVisited=true;
I'm not sure to understand what you want, but if you check the default generated file program.cs in the main, there is a line like that
So, what you could do is just a kind of manager that will keep the next form to run.Code:Application.Run(new Form1());
Code:Form f = myFormManager.GetNextForm();
while (f != null)
{
Application.Run(f);
f = myFormManager.GetNextForm();
}

Give them a key so you are able to differ between them and then use the key to access your dictionary to get a pointer to your Forms, which you just in the moment need to use. so you are able to easily switch between your Forms. Maybe you should think about having an MDI Form as Parent and MDI children as your Forms. Closing a Form in this case needs to delete it in the Dictionary too !
If you have too much troubles show your project as a zip file ( dont include any bin, nor object files ) and we will do a repair for you.
I think what he wants to create is a "Wizard", like an installer or something which takes you from Step 1 to Step 2 to Step 3, etc...
The way I would do it is simply create each 'form' (it can be a user control, a form, or anything else you want) as an individual entity that handles whatever particular functionality it needs. I would also use a common base class if there were going to be some common functions, such as a previous, next or cancel buttons.
Then I would just make the main application object a big state machine (which can be done directly as methods, delegates, lists, etc...) and it would invoke the first form and subscribe to it's next / previous / cancel events. It would hold all the data that is gathered and be responsible for hiding / showing the different forms. It it would know what was next or what came before it. It could make decisions such as skipping form #5 if it is not relevant and stuff like that.
Specifically, I would make each one of these "forms" a user control and the Main form would just have a big panel that it put these user controls in as needed. The main form would the common functions like next/previous while each user control was only a UI to gather whatever information from the user that it needed.
You could use a factory that could take a result from one of these user control and make the next user control for you. For example, form "Home" had a button to "Connect" or a button for "Settings" when the user clicked either of these, it could set a property (or event) that had a "NextForm" string. That string could be fed into the factory which would then construct the instance for the next form.
If you do it that way, then the main form code stays simple and dumb (which is good). If you wish to add / remove / change a transition from one of these user controls, you just need to edit that one user control code without touching anything else. IE: You want to add an "Advance Settings" to the "Home" form, you just add the button which sets the "NextForm" string and you are done.
