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.

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

I am trying to create an autorun executable that runs when the end user puts the cd in the drive. I would like it to have menus and buttons to open files that are on the disk, but have it check that the user has the programs to open the files.
PS I am using Visual Basic 2005 Express Edition
Any suggestions will be most appreciated

Your auto run program needs to be written in C++, unless you can guarentee that the .NET framework will be preinstalled on all PCs that have your CD put into them.
TO make it work, you just create an autorun.inf file on the root of your CD

Looks like I'll have to get glued up with C++ then.

I suggest you take a look at databindings to make all the assignation part a lot more easier and automatic
Also, in the combobox, you should set its datasource, to the same datasource you are using for the textboxes so it will change the row automatically when when the combobox selectedindexchanged event is raised

Hi,
What is the concept of NameSpaces in VB.Net
Nitin Jenwal
|
|
|
|

I'm not sure what you're asking ? It's the same as in C# or C++, a namespace is a way to partition code.

I don't know very much.
Namespace is collection of classes. for ex. system namespace in vb.net.

Hi,
What is objectbased & Objectoriented programming.
I am unable to distinguish between VB6 & VB.Net.
Please Guide

VB6 is a crap language, which is half way to being OO. object based is just a way of saying 'we tried and failed'.

Hi,
1)VB.Net is Advanced version of vb6. What is .NET in VB.Net,
2)What is framework.
3)If we create some application is it necessary to have framework to run that application(.EXE) on other machine
Please Answer my query.

1 - incorrect. VB.NET is a .NET language, which is fully OO, and which uses VB syntax. It is almost completely unrelated to the disaster that was VB6, although the visual basic namespace causes a lot of VB6 nastiness to still exist
2 - a framework is a base class library on which you can build code
3 - yes.
Did it occur to you to google any of this ?
