I was wondering if anyone has connected to the video camera using ez_B.dll from visual basic? I'd like to see a tutorial using the same method as was used in the tutorial for connecting to the servo via ez_B and Visual Basic.
Also, was wondering if anyone has tried to build a .BAS (visual basic module) for the ez_B functions so that the functions can be called from old versions of basic such as VB6?
For example, here is what the C# looks like...
Code:
And here is the project in VB
Code:
1: I set the CPU to x86 (BUILD..configuration_manager.)
2: Added EZB.DLL
3: added 3 combo boxes,2 timers to form1
4:added ALL of the EZB controls to the form,including videoplayer
Getting a bunch of errors..and mytoolbar disapeared
ERROR in following line of code:

For more information on using Visual Basic, check for online tutorials and classes. You may also check your local schools for night courses on introduction to programming.
My suggestion is to use ARC, then you can migrate to Visual Studio development. By then, you will probably wish to use C# because it is much easier than Visual Basic actually
I already am using ARC, I recently purchased VS 2012. I used to do a lot of VB6 enterprise programming using the API.(hobby) Did a lot of winsockDLL programming and also using ip/worksV4 which are activeX controls that will let you build a TCP/ip server(daemon)((up to 1000 connections) in about 30 mins. in VB and a tcp/ip client in 10 mins
I also used wsock.bas in my vb programs...
I'm planning of learning VB.net and then go on the VC#. I'm able to add all of the ip/works DLL's to VB2012 including Telnet.ocx,daemon.tcpclient,ftpserver and client,udp etc...
So, I'm experimenting : got the VB servos going, want to get the vb camera going...then maybe GPS...but one thing at a time.
I'd also like to try and build an app using vb6 and EZB.bas.avicap32.dll.
I really like it if you could add a step by step tutorial for VB camera as you did with the VB servo control.(that was great.)
Thanks
Again - I really need you to read my replies
1: Created new project in VB2012(vs2012).Windows form application.
2:select x86 CPU from BUILD-configuarton manager
3.Add EZB to toolbox.
4:ADD all of the EZB controls to form1
5:ADD 3 combo boxes and 2 timer controls to form1
getting errors when I run the app or build.
These are the error msgs I get
Error 1 Argument not specified for parameter 'captureHeight' of 'Public Sub New(ezb As EZ_B.EZB, captureWidth As Integer, captureHeight As Integer)'.
Error 2 Argument not specified for parameter 'captureWidth' of 'Public Sub New(ezb As EZ_B.EZB, captureWidth As Integer, captureHeight As Integer)'.
when I run the following code.
_camera = New Camera(EzB_Connect1.EZB)
Using the code found at:
http://www.devx.com/dotnet/Article/30375
I am able to get video from a wired video cam (NOT BLUETOOTH yet!).
If anyone wants to try the code and is having trouble, let me know and I'll give you the steps involved.
Still not able to get video using the EZB.DLL.
A book may help also - such as VB .Net for Dummies - which i know provide great instructions.
Figure I'll start with those and then move up to the dummy one:)
(I've got a bunch of Dummy books: there are great)
I've tried to follow the instructions...still didn't work...But I'll try it again...
Thanks

1) Simply download EZ-SDK
2) Extract the contents of the file to your desktop, or somewhere common. Like My Documents
3) Follow the directions within the README file
- The README file instructions are important. They will direct you to ensure the project is configured for 32 bit (not 64). It will also explain that you will need to remove any broken references to EZ-B.DLL. A broken reference will display an icon.
- The README will also explain that you need to add a reference to the EZ-B.DLL.
My screens are a little different but I think I checked everything...Had a ref to Forge.dll which i removed..
Runs with NO errors but still no camera...
I am able to connect to the EZ board...(on COM 9)
What camera are you selecting in the drop down?
I have the ez robot bluetooth and a usb wired logitech connected...
Before running the tutorial I checked and they both worked from ARC..
I ran the totorial and nothing shows up in the dropdown. I ran ez robot again and both are there and connect.
'The ListVideoSources() subroutine calls the capGetDriverDescriptionA() function and lists all the video sources in the ListBox control. Up to 10 video sources are supported:
'---list all the various video sources---
' Private Sub ListVideoSources()
' Dim DriverName As String = Space(80)
'Dim DriverVersion As String = Space(80)
' For i As Integer = 0 To 9
' If capGetDriverDescriptionA(i, DriverName, 80, _
' DriverVersion, 80) Then
'lstVideoSources.Items.Add(DriverName.Trim)
' End If
' Next
' End Sub
It first gets the drivernames using the dll
Then it adds them to the listbox...
I don't find the code in tutorial3 that gets the driver names....
