Aiight...will do that

It is WIA compatible..cos another project i tried shows the device in a common dialog box.
And btw...when it was being converted....visual studio asked if i wanted to change the framework to 4.0
and i said yes.
Will try that though.
It will run on windows xp sp2/sp3.

Well,when i ran the source in VS2010, it notified me that the code was targeting an older framework....NET 2.0...while i have 4.0
installed on my system.

The first issue is the code that searches for attached webcams.It always reports no video found even when
i have a webcam attached.This is the method that checks for webcams:

private bool CreateCamera()
    {
        bool done = false;
        CollectionClass wiaDevs = null;
        DeviceInfoClass devInfo = null;

        try {
            wiaManager = new WiaClass();

            object foundID = null;
            int foundCount = 0;
            wiaDevs = wiaManager.Devices as CollectionClass; // call Wia.Devices to get all devices
            if( wiaDevs != null )
            {
                foreach( object wiaObj in wiaDevs )
                {
                    devInfo = (DeviceInfoClass) Marshal.CreateWrapperOfType( wiaObj, typeof(DeviceInfoClass) );
                    Marshal.ReleaseComObject( wiaObj );
                    if( devInfo.Type.IndexOf( "Video" ) > 0 )
                    {
                        foundID = devInfo.Id;
                        foundCount++;
                    }
                    Marshal.ReleaseComObject( devInfo ); devInfo = null;
                }
            }
            if( foundCount < 1 )
            {
                MessageBox.Show( this, "no WIA video devices found!", "WIA", MessageBoxButtons.OK, MessageBoxIcon.Stop );
                return false;
            }

            if( foundCount > 1 )
                foundID = System.Reflection.Missing.Value;
            wiaCamera = (ItemClass) wiaManager.Create( ref foundID );  // ask user if more then one video device
            done = wiaCamera != null;
            return done;
        }
        catch( Exception ) {
            MessageBox.Show( this, "Create WIA camera failed", "WIA", MessageBoxButtons.OK, MessageBoxIcon.Stop );
            return false;
        }
        finally {
            if( devInfo != null )
                Marshal.ReleaseComObject( devInfo );
            if( wiaDevs != null )
                Marshal.ReleaseComObject( wiaDevs );
            if( ! done )
            {
                if( wiaCamera != null )
                    Marshal.ReleaseComObject( wiaCamera ); wiaCamera = null;
                if( wiaManager != null )
                    Marshal.ReleaseComObject( wiaManager ); wiaManager = null;
            }
        }
    }

OCA comprises of two modules:
1)Introduction To SQL...dealing with basic select statements,and stuff...which i wont mention here.
2)Database Administration Fundamentals I(Dealing with stuff like creating users and database objects etc).
In my own opinion, you can learn SQL on your own by reading materials and practicing on your laptop with an oracle database.(That's what i did).
But for Admin Fundamentals...you can also read on your own...then get someone to take you on the topics you do not understand for maybe one or two weeks.
(That's what i did too). When this is done.You are ready for the exams.
My advice is to write the SQL exams b4 u start the Fundamentals I materials.

My advice is similar to one already given.Start with html.Then learn how to use CSS.
After that move on to javascript. From there PHP.
With these under your belt,you can dive into either java/c#.

Hi all,i need help on a project i am working on that will need to capture an image from a webcam on "button click"
and store it in a MySQL database(along with other data) when the save/submit button is clicked.
The examples i got from the internet were all developed using visual studio 2005 and do not seem to work
(For whatever reason even after converting to .NET framework 4.0 using VS2010).
I am willing to show my code snippets to anyone that is willing to help.
Thanks.
