I use this to set the form size to a % of the screen size. It does not resize the objects but if you design your form with dock, anchor etc it works fine
Public Shared Sub SetFormSize(ByVal oForm As Form, ByVal nFactor As Decimal)
Try
Dim r As Rectangle = Screen.GetWorkingArea(oForm.Location)
oForm.Top = r.Height * nFactor
oForm.Left = r.Width * nFactor
oForm.Height = r.Height - (r.Height * (nFactor * 2))
oForm.Width = r.Width - (r.Width * (nFactor * 2))
Catch Exc As Exception
Throw Exc
End Try
End Sub
called by
clsUIUtils.SetFormSize(Me, 0.01)

What i have to do to be able to sell my applications? i make an application an sell to example (Bank) is that illegal? Please answer...

Nobody is stopping you. You can certainly create an application in VB.Net and sell it.

Why would anyone stop you ? Even if you use the free versions, your code is your intellectual property and you can sell it if you like.

1) You have to develop the software yourself .
2) All Components and Design must be your creativity .
3) All third party components used must have enough permission from the owner.
that's it for you, hope you make a good selling out of it.

You're doing a bad job of describing your homework. I hope you do a better job of doing it, or you will fail. We offer advice to people stuck with specific tasks, we don't do people's projects for them.
It's not even clear what sort of app you want to write. Of course it's possible with VB.NET.

My question is based on database record locking .
Like , can i lock the record after clicking the edit button.
This requirement occured due to the reason when more then one user to trying to modify the same record.
|
|

You can store in the database that a record is locked, using your own table design. There's nothing built in AFAIK.

That means , if I am having 10 client users , then I need to keep track on all the user names , and to note down , which one has opened the record for editing purpose ??? Is there any other way out?
I think it will become very complicated.

I was part of a project that ran for four years, which involved multiple users accessing documents in a database. In that time, no-one on that team was able to suggest any way of automatically locking records on a database, we didn't bother doing it ourselves, but we discussed the problem from time to time.

It seems standard practice is to include Modified field in your tables that holds last timestamp of the last modification of that record. When you go to get data from the database, you also make sure you grab the Modified field for your records. During the UPDATE, your SQL statement must match the recordID AND Modified time that you fetched. If the modified time doesn't match, the record has been modified by someone else while you were looking. The update will, of course, fail. This will mean that there is a concurrency violation and you'll have to handle this condition as you see fit.

Optimistic locking[^] would ensure that users cannot overwrite changes made by other users.
SQL-Server supports "Pessimistic locking" by allowing you to specify a "holdlock" hint on the select statement - within a transaction that spans the user's edit session. Only one person can hold the record-level lock at a time. However this approach can hurt database performance because (unless you use the fancy new snapshot isolation levels under SQL-Server 2005) any users selecting on the table will be blocked.

How do you plan to save the data back to the database?
If you are using ADO.NET, maybe you should let the users know if the save operation failed catching the DBConcurrencyException when you try to save with the dataadapter.update. If a record cant be updated because it was modified since it was last read by that user, then, just let the user know about it and give it the chance to refresh the record, show both version, or whatever you think is more convenient

My problem is based on Registry.
Like in HKEY_LOCAL_MACHINE
there are following items........
1.HARDWARE
2.SAMS
3.SECURITY
4.SOFTWARE
5.SYSTEM
can i programatically find out - using loops or any another way - to list these items , that comes under HKEY_LOCAL_MACHINE.I mean
if i write
dim len() as string = findsubkeys(HKEY_LOCAL_MACHINE)
i am just trying to make my problem clear y using a unrealistic function findsubkeys.
Thank You.

Have you looked at the GetSubKeyNames method of the RegistryKey class?
Dim HKLM As RegistryKey = Registry.LocalMachine
Dim subKeyNames As String() = HKLM.GetSubKeyNames()

Try this code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim str1 As String
str1 = (RTrim((LTrim(TextBox1.Text))))
MsgBox(str1 & "," & Len(str1))
End Sub
With Regards...

hello Nitin,
actually the LTrim and RTrim are the mehtods used to remove the blank spaces from Left and Right side respectively,
text1.text = "****Hello****" 'Take * as Blank Space
text2.text = Ltrim(text1.text)
the Text2.text contains = "Hello****"
and same for Rtrim and if U use only Trim then bothside blank sapces are removed.

Could you help me

The trim method, on the string class, will remove whitespace from both sides.
textbox1.text = textbox1.text.trim() will do it

Any suggestions will be most appreciated
