Hi Dave,
Thanks for your reply.
My usercontrol doesn't actually create and load forms. It raises an event that passes and index representing the button that is clicked on the control. My problem seems to be that the usercontrol seems to stay at front and the forms that get loaded are hidden behind. After clicking the button which loads a form I hid the usercontrol and I could then see the form?
In the code I do try to bring the loaded form to front - objForm.BringToFront() but this doesn't seem to work.
Does anything obvious stand out in my logic?
Thanks again for your time.
Regards
David

You missed the point of my reply entirely. Your MDIChild IS in front...of all other MdiChildren.
The problem is that all MDIChildren are rendered by the MdiClient control, which is BEHIND your UserControl. Your MdiParent has TWO controls on it, not one. The MdiClient control (which hold all of your MdiChild forms) and your UserControl. Calling BringToFont on the MDIChild form only brings it to the front of the stack of MDIChild forms INSIDE the MdiClient control.
You have to call BringToFront on the MdiClient control, or call SendToBack on your UserControl. But, that'll make your UserControl appear to disappear, when really, it's behind the MdiClient control.

Thanks Dave, will try to come up with a better solution than creating a user control for my purposes.
Thanks again for your time.

All classes are passed by reference, structs are passed by value. Is this what you meant ?

No Sir
I was trying the compression program
like in C++ storing the address of another variable.
I am now trying to store the address of another variable in vb.net
Please help.
Thanks and regards

In the world of Managed code, the address of a variable doesn't really exist the way it does in unmanaged C++. Any object or piece of code can be moved at any time, thereby invalidating any stored address you have on it. Addresses to code (function pointers) are handled by delegates in the .NET Framework. Variables are passed by reference, but that's not an address in the C++ sense of the word.
What are you trying to do with this?

Sir
i meant that can i implement the double link list in vb.net
Please provide help.

You can find a doubly-linked list implementation right here[^] on CP. It's written in C#, but is easily convertible to VB.NET if you want.

Sir/madam,
I am facing a problem in the interfaces.
I have a class named class1 which has the following implementation
class class1
implements inter
public sub abc()implements inter.a
messagebox.show("abc method")
end Sub
End class
Now i am creatin a interface
Public interface inter
sub a
end interface
Now i want the interface to implement in the window form named form1
public class form1
implements inter
private sub a()implements inter.a
end sub
now my question is ,
can i get the implementation of the function abc which is declared in class class1
without writing it here in the function a of class form1 again
If i have to redefine the implementation of the function abd of class class1
in the function a of form1 after implementing the interface in form1 class
then what's the use of the interface.
instead of the interface , i could not use the object of the class or making the function shared.
I mean what is the nead to to redine the same implementation again.
Interfaces compensates the multiple inheritance.
But the class where i am implementing the interface , i will write the code again there..
Finally what i want is , there is a funtion defined in the class .
i want to call that function in another class
without the use of object of the class or keyword shared.
i mean i don't want to write the same code again
can i make it possible using interfaces
end class
Thanks and regards

I don't think you have the right idea on what an interface is. It's not used to somehow allow multiple inheritance. I'll quote a book I have because it's better then what I can come up with.
"An interface defines only the signature of properties and methods, while a class can implement that interface by providing actual code for those properties and methods as necessary."
-Visual Basic 2005: The Language by Francesco Balena
All an interface is-is a definition of properties and methods to be included but does not supply the actual code. Each class must do that on it's own. So no, you can't write code in class1 and have the form class use it in the manner you have defined. Form1 class would have to write it's own code.
amaneet wrote: Finally what i want is , there is a funtion defined in the class .

You want to access a function but don't want to create an intance. Sounds like you want a shared function. So why do you say you don't want the shared keyword? If that's what you want I think your only option is a shared function.

The documentation on "Interface[^]" goes a long way...

The .NET Framework insulates most of the machine from your code. This really isn't necessary for a small app like yours. You're not doing anything that's really hardware dependant.

Hello,
[VS 2005]
I am new to working with typed dataset and currently working on a project and have decided to use them.
I have about 20 tables in my database that are used my program.
I have created several designers and dragged some tables on them and created the relationship.
I have tried to do this in a modular way. i.e. one for updating, deleting, customers, another for updating, deleting stock. So i have tried to keep this clean and tidy.
And I have ran into a problem of having many designers that use the same tables. the customers table could be used in many designers that i have.
I think that this has made a whole mess, and not sure if i should have created 1 designer and put all the tables in there. Is it better to create 1 designer and put all the table in there?
My program is only small and have about 20 tables but could grow bigger in the future.
In big enterprise application where lots of table are used, what do developers do in this case?
Does anyone know of any good tutorials for the best practices for doing this sort of design.
Another quick question when you create a relationship between the tables. There are options to create constraints and foreign key constraints. What is the difference between these options?
Many thanks for any good advice on this.
Steve

The database access code is usually written by hand, probably written with the help of something like Microsoft Data Access Application Block (see here[^]).
steve_rm wrote: I think that this has made a whole mess,
This is why we don't use the designers to generate all the code for us!
steve_rm wrote: Another quick question when you create a relationship between the tables. There are options to create constraints and foreign key constraints. What is the difference between these options?
You just about never need to do this unless you need the relationship inside your code. You can see an example here[^].

I have the timer counting 5secs til a form is closed, is there any way to link a progress bar to the timer (i.e. the progress bar shows the timer running down).
