Objectives: To Learn Advance On VB.NET Languages
Significance Of The Study: For being basis/example to us programmers especially to all beginners programmer.
I'm working on an application where I'm using an webcam image. I have code that works when using the built in iSight (It's an Apple running boot camp windows 7) camera. However after installing a second USB powered Microsoft Life Cam I am unable to connect to this second camera. When runnign this code I only ever get one input device:
Private Sub LoadDeviceList()
Dim strName As String = Space(100)
Dim strVer As String = Space(100)

View 1 RepliesI have a logitech webcam that I use to take pictures of customers to submit to a server/database. Utilizing AVICAP32.DLL calls, I was able to modify my VB.NET program to take these pictures via a button in my program.
My question is, it would me more convenient to my intended users to click the webcam button, instead of clicking on the button in my program.
Is this possible to do in VB.NET? and how can I do this?
If this is not possible to do with my logitech webcam than is there a Microsoft Webcam that can do this?
my system is already working. I used VB.net and mysql. i used ODBC DSN to connect .net to mysql. however i would like my system to run in a Local Area Connection.

I want some client to run this file with out share the file.If I can to creat a form by vb.net has a Username and password to run this exe without client know the userName and password.I'found map network , but is not ok for me.If I mapped network drive to client, then he can copy files and read some of security data.Is there a way to access this file from server without mapping or sharing folder for public ?
I'm developing a online document management application for my client using the following technologies
Front End - VB.Net 2010 (Windows Forms)
Back End - SQL Server 2008 R2 Express (FILESTREAM enabled to level 3)
I wanted to store the files (*.pdf, *.doc, *.exe, .) using the FILESTREAM feature in SQL Server 2008 R2.I prefer FILESTREAM because sometimes the file size exceeds 2GB.I'm able to save and retrieve file with FILESTREAM (using Windows Authentication/Integrated Security).But my client wants to save or retrieve the file from different PC.So I'm in need of accessing the FILESTREAM BLOB from remote systems.
An Error has occurred while establishing a connection to the server. When Connecting to a SQL Server2005, this failure may be caused by the fact that under the default settings SQL server doesn allow remote connection (provider: Named Pipe Provider, error: 40- Could not open a connection to SQL Server)I want to connect to the SQL Server 2005 Express Edition which is running on my system from a VB.NET application.

I have been programming vba for some time and am now starting VB.NET. I need to connect to an existing access db file (access 2003). I downloaded VS2010 and found an example on the net. Here is most of the code:

Dim cn As OleDbConnection
Dim cmd As OleDbCommand
get the argument for the desktop of the user
I am getting this error message:

I have tried with System.Management class, but no use..

We have a VB.Net application which works fine in our tests in different Windows XP SP3 machines. However there is one machine in which is displaying this error:
Unable to connect to any of the specified MySQL hosts
Using the mysql command, we can successfully connect to the database. We already checked for any other application or firewall that could be blocking the connection but it seems fine. We also reinstalled the system (no errors during the installation) but the MySQL error message doesn't change.
The system settings are exactly the same as in the other computers. We are using "localhost" as server in the connection string. The "hosts" file has its default values (nothing strange in there).
I am trying to connect to my remote MySql Database within Visual Studio using the compact framework.
I can successfully add a data source and preview the data within the IDE so assume that the connection is ok regarding Connection strings and remote access.
However, when I attempt to access the data using any run time control I get the following error when the table is loaded using the .fill method.
MySql.Data.MySqlClient.MySqlException was unhandled
ErrorCode=-2147467259
Message="Unable to connect to any of the specified MySQL hosts."

I want to capture a still picture in any format like .png,.jpg,.bmp etc. using a webcam.And want to save that in directory.
View 3 RepliesI use VS2008 with Visual Basic and VB.Net. I am writing an application to save videos from a webcam, and I've found several examples that provide the basic functionality, so that I can now start and stop the webcam, and save a video as a .avi file. However my interface is still clunky: when video capture starts following
SendMessage(hWnd, WM_CAP_SEQUENCE, 0, 0)
then the window is locked and the [Stop Capture] button doesn't function, so I need to exit the window to stop capture.The documentation at Video Capture [URL] has a lot of methods that look useful, and I think that I need to link up a callback function to allow [Stop Capture] to function, but I can't figure out from this documentation how to send a WM_CAP_SET_CALLBACK_VIDEOSTREAM message to do this. I don't know how to control the formats so that I generate video files that are concise enough for web use - changing the frame rate or dimensions seems to have absolutely no effect Is there any general tutorial that will cover all of the messages in AVICAP32.dll, and show me how to implement them in VB?

View 2 RepliesI'm trying to take a picture from my webcam when the user clicks a button on a Form on a Windows XP Machine.
I tried going through several threads, but couldn't find the solution I was looking for. Most of the threads involved matters (and code) too complex for my requirements, or had bugs when I reproduced the code in my editor window which I was unable to resolve due to my lack of knowledge in I/O related programming.
So far the simplest solution I could find was this one:[URl]...but after using his solution in my editor, it says 'type WIA is not defined', despite adding a reference to Microsoft Windows Image Acquisition 1.01 Type Library.

View 1 RepliesI wrote some software that use the AVICAP32.dll to do a spot of video capture.All was going well till they went and bought a laptop with a built in webcam.Now my software picks one a random and uses that for the video (somewhat annoying to say the least) Can anyone tell me how to pick a camera to use,I suspect it is related to DVM_DIALOG but my experiments have not been too successful.
