I am in a club at school called BPA, which stands for Business Professionals of America. I am in the visual basic .NET division. I made it past division test and now I am going to state. I have no idea what to expect from the state competition, so I have been studying the test I was given at division. The test was pretty easy. The only trouble I had was with the usercontrol and connecting to a MS Access database. I was using VB 2003 (had to do this test at school) so I didn't know how to connect to a DB in 2003. I will be using VB 2008 at state (cause I am bringing my laptop). So I guess my main reason for posting this is that I am looking for some projects that I can build that while help increase my VB proficiency. I am getting tired of just rebuilding the project from division. I am mostly looking for projects that are business like because I think any test I will take for BPA will be related to business.
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'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)
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 have a Dll project written in VB.Net 2003 which compiles a Dll used in other projects. I need to debug this Dll while it is being ran in the other project. Does anyone know how I can do this, or do I need to integrate it into my other VB project somehow before I can debug it?

i have done some research on converting an existing app to VB.NET, but have not found what I am looking for.
My existing app is currently created in Access 2003 VBA using access forms, modules, tables queries etc., and would like to convert all of it to VB.NET.
What would be the best method or tools to use to accomplish this? The VB.NET app would be developed from VisualStudio 2005..
I created a VB.NET winforms project using Visual Studio 2003, including reports done with CRystal Reports. I need to upgrade the system to the latest VB.NET using Visual Studio 2010. What kind of problems can I expect? How difficult will it be to convert the reports to Business Objects (which I believe is now th default in V Studio).
It's not a huge system about 6-8 screens and a similar number of reports using an Access 2000 Database. Most of the screens were coded directly in VB and not done with the automated processes at the time.
but nothing prints. The app exports to pdf works in test, but not when I move it to production. I have to remote into the machine that runs the app, so my printers from my local pc are "attched" to the remote session, can this have something to do with no output. The remote machine does not have the Adobe print drivers installed.
I'm working with Visual Basic.NET 2003.I want to get an image file from my .resx file which I made using Resourcer.exe, and use a button to put it in a PictureBox. I haven't been able to make the code work, which I found by surfing the net. I did succeed in loading the picture through the designer, after using WinResourceWrapper.exe., but I would rather use code in order to use the same PictureBox.

I'm doing database development in Access 2003, and the Visual Basic portion of it is acting up. It seems to be "refreshing" itself constantly. Two very frustrating problems are occurring because of this: 1) Intellisense for properties and such pops up but immediately disappears and turns red and 2) it's automatically checking the syntax of lines before I can finish typing them.
The problem seems to be intermittant. Some forms in the database operate fine while others immediately turn the line red two seconds after I start typing. I am having this problem on both of the computers that I use on a regular basis.
