when I use the Me.Visible = False code , instances of my application are still running unseen

Ummmmm....who told you that Visble=False will clsoe an application??? Confused | :confused:

That just hides the window you set it on, nothing more. So, yeah, the app is still running...

You'll have to use the Process[^] class, and it's GetProcessesByName method, to get an array of Process objects. Then you can call Close on each of those objects to close every instance of your app.

I'm beginning a new VB.NET WinForms app for my company. They have chosen to use VS 2005 for this project. I've been programming in 1.x for a while now, but I haven't really kept up on the changes/additions to 2.0.

Does anyone have any suggestions for books/websites/etc. where I can get up-to-speed on 2.0? I would prefer a book, but I don't really need a "VS 2005/.NET 2.0 for Dummies" book (or do I?) A website (or combination of sites) would be fine as well, though I don't really want to try and wade through MSDN to find what I need if I don't have to...

Anyway, any suggestions would be greatly appreciated. Thanks!

P.S. From what research I have done, having VS.NET 2003 and VS 2005 installed side-by-side on my machine will not be a problem. I don't have drive-partitioning software, so they will literally be side-by-side. Is that really the case?

Check out this article on MSDN. It pretty much covers all of the new VB.NET 2.0 language features.

Yes, that is really the case. I have 2003 and 2005 installed side by side, and both work great. Only problem (not so much a problem, as a minor annoyance) comes from the OS. When I double click on a file, Windows doesn't know if it's 2003 or 2005. It opens VS 2005 by default. So what I do is right click on the file, and choose "Open with - Microsoft Visual Studio 2003" if I need it. (Of course, if most of your work is done in VS2003, you could set that as your default)

Asside from that, no problems. Big Grin | :-D

You need to call the Win32 function ShellExecute.
First add this line to the top of your source file.

Private Declare Function ShellExecute Lib "shell32.dll" Alias _
   "ShellExecuteA" (ByVal hWnd As Long, ByVal lpOperation As String, _
   ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, _
   ByVal nShowCmd As Long) As Long

You can now launch the calculator program by doing this...

ShellExecute vbNull, "open", "calc.exe", "", "", 1

Another neat thing here is that you can also launch URLs and open documents like TXT, DOC, PDF, etc. with this. ShellExecute is the equivalent to double clicking a file in Windows Explorer.

Passing parameters to COM+ service

13-Mar-06 10:29

You'll have to run this code in the debugger to find out on what line the exception is being thrown. But, you're trying to do something with an instance of an object that doesn't exist, or is Nothing. Without seeing the section of code that is having the problem, that's pretty much all we can tell you.

I'm having trouble passing parameters to a COM+ service. The only code I could find to do so uses XML (see below). This works, but only certain characters are allowed. Unfortunately I am passing a stream of text that includes chr(12) formfeeds and XML of course does not like this.

Any suggestions?

Exception Management in Enterprise Library

Hi,

Using the Exception Management Application Block I can create new logs in the Event Viewer by placing the following in my app.config file:

<exceptionManagement mode="on">
<publisher
assembly="MyAppBlockTest"
type="MyAppBlockTest.ExceptionPublisher"
logname="My Test Log"
applicationname="Exception Management Application Block Test"
fileName="c:\errors.txt">
</publisher>
</exceptionManagement>

I am now trying to use the Enterprise Library and I don't know how to create a new log. I can only write to the default Application log. Can anyone tell me how I can do this?

Thanks very much,

Database Connections using VB.Net 2005

13-Mar-06 10:30

How you'd do this would depend heavily on what you're using to get the video stream and what you're using to display it. Each library is going to have, if supported, it's own methods for doing this.

i am having problems connecting remotely to the existing database in visual basic .net2005 for connection string .
please tell me how to configure sql server2005 for remote database connections and which connection string should i use to make it working. Confused | :confused:

JUNEYT13-Mar-06 2:15

13-Mar-06 2:15

I got the same problem with 2005 and decided to use a connection string manually and then the problem has been solved... Use a connection string variable as shown below:

Public ConnStr As String = "Provider=Microsoft.jet.OleDB.4.0;Data source=" & Application.StartupPath & "\Database\lyrics.mdb;Jet OLEDB:Database Password=111111;"
Smile | :)

Dave Kreskowiak13-Mar-06 7:27

The string you provided is for an Access database, not SQL Server 2005.

You are abosuletly right David! It was my out of attention. anyway. He can rich the information at www.connectionstrings.org or .com

Dave Kreskowiak13-Mar-06 7:36

SQL Server 2005 has a tool called the SQL Server 2005 Surface Area Configuration tool. You'll find it under Start/Programs/SQL Server 2005/Configuration Tools. Start that, then click on Surface Area Configuration for Services and Connections. In the left side navigation pane, click on Remote Connections. I think you can figure it out from there.

As for the connection string, a basic string using standard security would look something like:

Dim connStr As String = "Data Source=serverName;Initial Catalog=databaseName;User Id=userId;Password=password"

You can find more on connection strings at http://www.connectionstrings.com[^].
