Err, I see, txtUsername is private huh?
define a property:

<br />
public string Username<br />
{<br />
get{return txtUsername.Text;}<br />
}<br />

So, in main form:

<br />
stripLblLoginAs.Text = "Login As :" + login.Username;<br />

set the txtUsername as public, or just define a public variable in child form.

See, apart from being ugly as all sin, that plain doesn't work. He wants to send a message back to the parent, so how does the parent know that the child value has changed. Delegates solve both these problems, they are not ugly and they go in any direction.

I admit that it's ugly. But it works.

Yes, but some of us write professional code, not just whatever works ( and your solution still does not work )

It also breaches one of the tenets of Object Oriented programming.

Why don't you the login form as a dialog?

i prefer a form with textbox nicer and more professional

Forms can be shown as dialog and return a DialogResult, that makes things simple.

Yes, if the form is modal, then it makes sense to do what you suggested, I just assumed from the question wording that it was modeless. In that case, I apologise, I would use properties and the DialogResult to return a value from a modal form.

You can in your child form's constructor set a field to the opener of it, then at anytime call any method on that form using its reference called. ex:

class Parent
{
public void Anymethod(){}
public Parent()
{
Child c = new Child(this);
}
}
class Child
{
private Form Owner;
public Child(Form f)
{Owner = f;}
public void CallParent()
{
Owner.AnyMEthod();
}
}

Hi,
I have problem for developing in OO style, I know the basic of OO.
which refrences are suitable for this purpose?
(with examples)

Best wishes

Hmm.... I think that OO thinking really comes more with practice, but Microsoft has a book, called Object Thinking.

When you know the mechanics of object-oriented programming but you don't really know how apply it to a well-thought out application, this is a pretty good book:

"Object Design: Roles, Responsibilities, and Collaborations"...

Hi
How to create collection class??
I have to save more than one rows in Database.I think collection class is the best way of doing this type of task.
Or Is there any other way of doing this type of task?

Thanx

Why would you ? The built in ones work just great.

OK - you mean you need to store into the actual SQL database ? Then you need to write SQL, not use a collection class.

Sounds to me like you know some terminologies but not what they mean, have you worked through a beginners book, or are you learning C# on the job ?

Hi Evry1..
I have couple of Picture Boxes ... If I mouse over on a picture box it should be highlighted...How will I do that using c#

sample code is appreciated..

regards,
Subhash.

By handling the mouse events and drawing a box around the picture box, I guess. Personally, I'd ditch the picture box, draw the images yourself, and have far more options for how to highlight them.

hi Christian...
Can u be Presice .. As i did not understand...
If Possible can u please send me the sample code...

thanks in advance..

Well, it would involve actual programming.

In your class, handle the Paint message. In there, draw your picture. Have a boolean flag to say if the mouse is over the image. When the mouse moves, set that bool and call Invalidate() if it changes, to redraw the image. In the paint event, draw the highlight around or over the image ( for example, I'd consider a semi opaque box over the top of it ), if the flag is true.

hi Christian,
I dont understand what you want to say ? I try to use google api but i ahve to pay for this.

I am not sure why you created a new thread here.

Torrents are basically tools for thieves, that's what I was trying to say.

What google API costs money ?

Although mostly not, there are surely exceptions to this rule?

Knives are tools of thugs, but used for their intendded purpose they cut food quite well!

edit: Have a read[^] - there are plenty of legit uses of the Bit Torrent protocol.

There are many, many things distributed through torrents, and not all of them are illegal.

Cheers,
Vikram.

The hands that help are holier than the lips that pray.

Perhaps - but what are the odds ? What percentage of people using torrents do so for legal reasons ?
