Forms are classes yes? These means at runtime they are objects yes? Therefore we can rewrite your question thus:
what is the easiest way to transfer values from child class to parent class.
what is the easiest way to transfer values from child object to parent object.
That said, if you do not know the answer to this then you need to obtain and study some beginner programming materials.

Well I can say if you make a class which is global then can tranfer parent form to child form . The easiest way is
example if your form1 have
textbox1.text = "....."
and if you want to show that string in another form name form2
it would be
label1.text=form1.textbox1.text
then it would show the string have in your textbox1.text
Hope it will help you

If you have gone through the code from the article, and understand it, you should have no difficulty in implementing the additional functionality that you require.
If, on the other hand, you do not understand what you have already done, there is no point in trying to modify it.
Write some code, give it a try, and then come back here when, and if, you get stuck on a particular part of the code.

Well,i understood the code little bit,as i am just a beginner..i need this job done urgently..so i thought that i'll get some help on this forum in doing this...
Is it possible to do what i am looking for?
like automatically an email along with the attachment should be send to an email address,only when the user has logged in,into that particular account?

As I said before. Write some code, then ask specific questions about specific problems.
If the problem is that urgent you will need to get your wallet/credit card out. My daily rate is quite reasonable, or there is always rent-a-coder.
Questions like "I want an app to help me rule the world. Any one got the code for that?" tend not to get answered.

I would like to copy file from local to remote machine using WMI in C++. Not quite sure how to do this.
According to MS doc, "Win32_Directory" can be a good candidate. Anybody got idea? Thanks in advance.

Why use WMI when you can just use the normal file methods??
And you should really be asking this in the C++ forums, not Windows Forms.

I have a datagridview with hundreds of records.
I need the datagridview content be frozen when I'm scrolling vertically using vertical scroll bar. Like in Outlook. The problem occurred because I don't want to repaint the grid by my rules when the visible part is changed.
How can I freeze that?
|
|
|
|
|
Do you mean keep the cells static with just the scrollbar thumb tab moving?
If so, I don't believe it is possible. DataGridView doesn't have a BeginUpdate method, which anyway would freeze the scrollbar as well. It does have SuspendLayout()/ResumeLayout() but the same problem applies to them.
Of course, now that I have said that, someone will post an answer.

Yep, I want to keep the cells static as you said. Still spending much time on this problem and no good solution...
|
|
|

Do you want to:
- Keep the first column visible when scrolling to the right? (horizontal scroll)
- Keep the first 10 records visible when scrolling down? (vertical scroll)
If you pick the latter, then the question rises what you'd expect to display?

Nothing regarding horizontal scroll now. Only vertical.
Say, I see 23 rows visible in a grid. On scroll down I want these rows been frozen and not moved until I released the mouse key. After that I'd like the grid to be repainted to show the new real amount of data that I've "virtually" scrolled down.
Does that make sense?
P.S. Look at the Outlook - the same way.

As Henry already stated, it's not something that comes out of the box. Using SuspendLayout as mentioned, perhaps Invalidate()-ing the scrollbar-region while dragging/moving the mouse. Or overriding the paint-handler, which might prove equally challenging.
I know that Outlook 'feels smoother', but that's probably not a .NET component in there. There may be some other third-party components that offer this functionality though.

Does anybody have an example how to override the OnPaint event or use the Invalidate() in my case?
|
|
|
|
|
Takhir, did you find a solution for this? If so what have you done?
|
|
|
|
|
I did nothing special there, actually.
But I re-written the OnPaint event on grid Now it works MUCH better and faster.
