There's something you haven't shown in the POINT2.New constructor. This message shouldn't come up with the code that I've seen and what I posted. The code that I posted came straight out of VB.NET 2005 and it compiled nicely.

Can you correct this conflict in two methods with similar names but different parameters.
<code>Public Type MyPoint
x As Double
y As Double
End Type
Public Type MyLine
Head As MyPoint
Tail As MyPoint
End Type
Public Sub DrawLine(aLine As MyLine, Canves As Form)
Canves.Line (aLine.Head.x, aLine.Head.y)-(aLine.Tail.x, aLine.Tail.y)
End Sub
Public Sub DrawLine(aLine As MyLine, Canves As PictureBox)
Canves.Line (aLine.Head.x, aLine.Head.y)-(aLine.Tail.x, aLine.Tail.y)
End Sub
</code>

What conflict? What's the errot you're getting?
I see other things wrong that have nothing to do with Overloading, Shadowing, or Overriding.

I'm new to the VB.NET world so any help will be appreciated. I'm building a Windows app and I have a form with tabs. On the first tab, I'm building a search capability. I have a couple of text boxes and a data grid. Everything seems to work OK, however in my datagrid, one of the columns displays a social security number. My problem is I cant figure out how to format the SSN column to display with dashes. Right now it displays as '#########' and I need it to display "###-##-####'
Thank you in advance for any help.

I'm also a newbie, but have come across this in VS2005. Use the 'Masked Textbox' and specify a mask or 000-00-0000.
If this control is not a part of your version of VS, you can convert the SS number to a string (tostring) and parse it using 'substring'
Dim sParse as String<br />
Dim sSS as String = ""<br />
sParse = iSSnumber.tostring<br />
sSS = sParse.substring(0,3) + "-"<br />
sSS += sParse.substring(3,2) + "-"<br />
sSS += sParse.substring(5,4)
Hope this is right,
Karen

Take a look at this[^] article here on CP. The code is in C#, but if you look close enough, you'll see that it is easily convertible to VB.NET.

 I've edited the normal.dot file to add certain styles to documents created in Word 2003. These styles would only worked in new documents and not old ones. I created a macro and attached it to a toolbar button, which will add these styles to any documnet whether they are newly created documents or not. Yet my dilemma, is having the styles in this newly created normal.dot file activate no matter who's logged in to the system. I was worndering if there's a Currentuser or username variable that would accomplish this task for me. Any help would be greatly appreciated.
Thank you,

I want to do the following.
I have a tab control with 3 tab pages. When I click on the say tab 1, then a procedure automatically starts.
If I put the procedure in say, TabPage2_Click, then I have to physically click on the tab. What I am aiming for is that when I click the tabPage of the Tab Control, the procedure automatically runs.
I have been trying various ways using TabControl1.TabPages(1) but with no success. I know this must be a simply process and I am missing something out.

Have you tried combining all the tabpage handlers into one event handler?
See the "Handles" clause at the end of your TabPage_Click event handler. You can add a comma then the next object and event that this code will handle. When any of the classes in the Handles list fire's it's Click event, this handler will be called.
Public Sub TabPage_Click(...,...) Handles TabPage1.Click, TabPage2.Click, TabPage3.Click

You posted this very question an hour ago? Don't repost, it's very rude and it won't get your question answered any faster.

Could somebody tells me the way to create string/array math using visual basic? Thank You!

What do you mean by a "string/array math"? This doesn't make any sense at all, so we couldn't even begin to tell you anything useful.

If you want to know about array of strings
Dim ArrayOfString(0 to 3) as String
Redim Preserver ArrayOfString(5)
ArrayOfString(0)="Put "
ArrayOfString(2)="What "
ArrayOfString(3)="You "
ArrayOfString(4)="to "
ArrayOfString(5)="Save."

Without seeing your SQL update code, it's impossible to tell you what your doing wrong.

Are you sure there's no name property (I don't remember it by heart)?
Anyway, an easy way is give the tag property the same value of the name and recall that one.

Hi all,

Hello
For changing the button picture you need to drag an imagelist on the form. Add as many images as you like in the imagelist. Now to show any image on the button you need to select the imagelist in button's 'imagelist' property. Now all the images you ve added in the imagelist are visible to your button. Use 'ImageIndex' property of the button to change the images.

For playing sound...use the following
Public Const SND_ASYNC = &H1 ' play asynchronously
Public Const SND_LOOP = &H8 ' loop the sound until next sndPlaySound
Public Const SND_NOSTOP = &H10 ' don't stop any currently playing sound
Public Const SND_NOWAIT = &H2000 ' don't wait if the driver is busy
' Use the following library
Private Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long
' call
PlaySound("FilePath And Name", 0, SND_NOSTOP)
