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.

Thanks,
I agree that that sounds like the problem from my research.
I have no clue how I would provide an instance of the oblect (I more use to borland c++ circa 1992)
I found the following in the docs regarding the method
HRESULT ProcessXMLFile ([in] BSTR filename,
[out, retval] BSTR * errors) ;
and
Method ProcessXMLFile This method is used to process an XML document stored on disc,
and uses the following parameters:
Parameter Description
BSTR filename File name and path of the XML document.
BSTR * errors Output error string.
Cheers

Once you import your COM library, are you creating an instance of the stub class it provides ? If not, you've not got a COM object to call methods on. What's your actual code look like, is it
MyCOMObjectInstance.ProcessXMLFile("whatever")
Or, was the line of code exactly as you posted it ?

Christian,
Thanks a lot for your help, the mud becomes ever clearer.
I was calling with as posted, I changed it as you suggested and it fires the method.
Of course I now get a new error, but hey no one said it would be easy.
Thanks again

I set out to write a Generic function that would find controls of a desired type and pass back an array of that type. For instance I could call the function and ask for all textbox's found on a form. However, I ran into a snag. I can test if a control is of Type T, but I have know way of converting that control to Type T. The following code shows the compromise I had to make due to this limitation.
'Returns a control array full of controls that match the desired type
Public Function ControlArray(Of T)(ByVal container As Control) As Control()
'Controls to pass back
Dim list As New List(Of Control)
For Each ctrl As Control In container.Controls
'If child control is of the desired type T then
'add to list
If ctrl.GetType Is GetType(T) Then list.Add(ctrl)
Next
'Return array
Return list.ToArray
End Function
Ideally this function would look something like the code below. The big difference is I want to return an array of type T. But how can I possibly convert a generic control to an unknown type?
Public Function ControlArray(Of T)(ByVal container As Control) As T()
'Controls to pass back
Dim list As New List(Of T)
For Each ctrl As Control In container.Controls
'If child control is of the desired type T then
'add to list
If ctrl.GetType Is GetType(T) Then
'The next statement won't compile and is the major problem I
'need to work around
list.Add(DirectCast(ctrl, T))
End If
Next
'Return array
Return list.ToArray
End Function

You need to constrain your generic statement. In C#, you'd do it like this
public List<T> ControArray<T>(Control container) where T : Control
Not sure of the VB syntax.
