I'm using the free express edition so your's may be a little different. Probably all you need is a registration number. Check the box, it might have a number for microsoft in which case you can probably pay by phone and get a registration number. Otherwise you could probably get it from microsoft's website.
If it is like my copy of vb.net then there should be a menu saying "register product" under "help". Just enter the number there.

Thank you very much for your suggestion. I also have visual basic express edition. But it is a limited edition. Because I need more capability on software development, so I need to use vs 20005 pro. Thank for your help.

How can I crop a circle/oval out of an image?
Any example would be helpful.
|
|
|
|
|
You can create a texturebrush using the image, use a translate transform to set the starting corner of the oval, and draw your oval using the brush.

I found this in the help section but how do I call it from the button1 click event, I get Argument not specified for parameter e
Public Class Form1<br />
<br />
Public Sub TransformExample(ByVal e As PaintEventArgs)<br />
<br />
' Create a path and add and ellipse.<br />
Dim myPath As New Drawing2D.GraphicsPath<br />
myPath.AddEllipse(0, 0, 100, 200)<br />
<br />
' Draw the starting position to screen.<br />
e.Graphics.DrawPath(Pens.Black, myPath)<br />
<br />
' Move the ellipse 100 points to the right.<br />
Dim translateMatrix As New Drawing2D.Matrix<br />
translateMatrix.Translate(100, 0)<br />
myPath.Transform(translateMatrix)<br />
<br />
' Draw the transformed ellipse to the screen.<br />
e.Graphics.DrawPath(New Pen(Color.Red, 2), myPath)<br />
End Sub<br />
<br />
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
TransformExample()<br />
End Sub<code>

Wow - that's almost entirely useless.
1 - your function needs a PaintEventArgs, you've not passed it one, that's why it won't compile
2 - that code is creating an ellipse and moving it on the graphics object, It won't crop anything, and it's just too complex for what it does (draw an ellipse )
A painteventargs comes from a paint event, this code assumes it will be drawing an ellipse within a paint event.
Try doing what I suggested.

You can see why the vb.net help files are no help.
and why people trying to learn vb.net (like me) give up.
There are just not enough good example to play around with.
|
|
|
|
|
No, the reason peole give up is that they don't ask, or don't take advice. Here[^] are plenty of examples on how to use a texturebrush ( I already told you this is what you need to do ).

Finally got it all sorted and it had nothing at all to do with
texturebrush, translate transform.
|
|
|
|
|
I have no doubt there was more than one way to do it, but using a texture brush would have been the easiest.

I'm writing a program where I need to capture sound from a microphone and get it into an array in my program.
I've looked around the internet for a tutorial on this but all I get is a bunch of tutorials about playing sounds, special effects, or other irrelevent information. The few times I do get something relavent it's always writen in c++ which is not a language I'm strong in.
If someone could tell me how to do this or direct me to a tutorial on how to do this preferably in vb that would be a big help.
thanks,
Mike

I am trying to call a function in a dll which was written in com
I am uing the following
Dim myxmlobj As New serviceprovider.ProcessXML<br />
Dim returnmesg As String<br />
<br />
returnmesg = myxml.ProcessXMLFile("c:\myxml.xml")
I have a added a reference to Interop.ServicePorvider in my project.
All seems correct but the funtion fails (Giving HRESULT E_Fails), is there anything special I need to consider as I am a calling a com dll.
Cheers

If you create an image from a file, you need to call Dispose on that object in order to free the file.

Then you're holding a reference somewhere. Do it when you load the image, write a load routine which loads, copies in memory and disposes of the original

Iam currently wirting a vb.net 2003 dll which links to a 3rd party com dll.
I have successfuly created a com class project and registerd the dll using regasm.
There is very little docs (not a surprize) and when calling the below function
ProcessXMLFile("C:\myxl.xml)
I get a bulid error saying "Reference to a non-shared member requires an object reference"
I have found lots of refrences to this error online, but none that help in this situation.
I relise the information is a little thin, not sure I have any more info but if you need more ask and I will try and provide.
Thanks in advance

Sounds to me like the ProcessXMLFile method is not static, and so requires an instance of an object to call it from. As you say, not much to go on, so I'm guessing'
The other thing is, your quotes are not closed, I asume that's just a typo in your post, not in your code.
