Got it to work by running visual studio NOT in Administrator mode and then rebuilding/installing. Seems the run as administrator has some sort of effect on the end build. Anyone else run into this?
EDIT: This still doesn't work on a different deployment machine running on Windows 7, only on mine.

Bump what? Post bumping does no good around here.

I have seen other problems caused by using "Run as Administrator" for example: One of my programs automates outlook and if I use run as administrator then it fails to automate outlook with a strange error
I have no idea why and as it works when run normally I haven't investigated further

Thanks for the reply!
Yea, seems websites on the local IIS need to be ran as administrator, but doing this with projects causing some issues. Yay for Windows 7 security issues.

Hi
I haven't been programming for a while, nearly 3 years. So I thought I should refresh my programming knowledge. Last time i did something with vb.net was with Visual studio 2005. But now I have VB.net/VS 2010 available.
How much changes have it been to the language since I last was active? Is all my old textbooks worthless, or can I use these to get up to speed again?
I've also considered to "jump ship" and switch over to C# since I might have to spend some time to get up to speed again.
Any feedback?

You'll be fine, yes things have evolved, but it extensions to the core, so you don't have to pick them up straight away.
As for C#, you could learn that in parallel, the classes are basically identical and you will soon pick it up.

If I install Visual basic 2010 Express edt. will I encounter any problems if I at a later time install Visual Studio 2010 Professional edition?
Any ideas?

I wouldn't think so, but VS pro does everything + more of VB express, so i would uninstall VB express.

Have a look at the VB dev center and some of the articles there. they'll give you a good idea of what's new. the most important changes are around LINQ and lambda functions. Then the new stuff in VS 2010 is mostly to do with features that were in C# 3 but not in VB 9, e.g., automatic peoperties, statement lambdas.

I am just getting into using the new TPL library with .NET 4 and I am getting an error when I invoke a sub routine.
The error is cross threaded operation however the error is happening on the line where I dim my myReader variable which is a mySQLDataReader.
I am probably being dense but it seems that would not produce a cross threaded error because I am creating it on new thread.
Any insight would be great thanks.

Hello ! I'm having a problem with catching all unhandled exceptions, without try ... catch block, so that if my program get's exception that I didn't count on, it could write it to file or send it to me over the net and close "nicely".
So far I've been using this:
' Add the event handler for handling UI thread exceptions to the event.
AddHandler Application.ThreadException, AddressOf ErrorReporting.ReportError
' Set the unhandled exception mode to force all Windows Forms errors to go through
' our handler.
Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException)
' Add the event handler for handling non-UI thread exceptions to the event.
AddHandler AppDomain.CurrentDomain.UnhandledException, AddressOf ErrorReporting.ReportError
and it was working perfectly ... Until few days ago  Now it doesn't catch anything. Even when I'm running program from Visual Studio 2010, if unhandled exception occurs, my program just shuts off, and Visual Studio doesn't show me where exception occurred or what the exception was ...
Please help me somehow, because this is very frustrating, and it's making programming impossible ...
Thanks

After trying everything, I've created new project and started to copy parts of my project in which error handling is broken ... And I've found out that my application catches all exceptions until this line:
req = CType(HttpWebRequest.Create(New Uri("http://test.com")), HttpWebRequest)
So what's the problem ? I don't think that I've did any thing wrong. Another interesting thing is that if I change my project to .NET framework 4.0 (currently it's 3.5), it works OK ... So is this kinda of bug in 3.5 or what ?
Thanks

Read this line from the docs;
Do not use the HttpWebRequest constructor. Use the WebRequest.Create method to initialize new HttpWebRequest objects. If the scheme for the Uniform Resource Identifier (URI) is http:// or https://, Create returns an HttpWebRequest object.
Based on this, you should be doing;
req = WebRequest.Create(), no need for any ctype.
|

I've tried to replace
req = CType(HttpWebRequest.Create(New Uri("http://test.com")), HttpWebRequest)
with
req = WebRequest.Create(New Uri("http://test.com"))
but the result is the same - program can't catch any error after that line ...
As for using CType, I must use it because I've turned strict on in my project

The event handlers for Application.ThreadException and AppDomain.UnhandledException have different parameters, so I doubt your code is correct as it uses a shared handler method. I suggest you check the documentation, fix the problem, and start your source files with Option Strict On.

In my last post I've told daveauld that I've turned strict on in my whole project 
As for Application.ThreadException and Appdomain.UnhandledException, I know that they have different parameters, that's why I have overloaded ReportError sub, so that they booth can use it 
Like this:
Public Sub ReportError(ByVal sender As Object, ByVal e As System.Threading.ThreadExceptionEventArgs)
Try
MsgBox("Unhandled error has occured !!" & vbCrLf & vbCrLf & e.Exception.Message & vbCrLf & _ErrorTitle & " will now close.", _
CType(MsgBoxStyle.OkOnly + MsgBoxStyle.Critical, MsgBoxStyle), _ErrorTitle)
WriteError(sender, e.Exception, "Yes")
If Not System.Diagnostics.Debugger.IsAttached Then
Application.Exit()
End If
Catch
End Try
End Sub
Public Sub ReportError(ByVal sender As Object, ByVal e As System.UnhandledExceptionEventArgs)
Try
MsgBox("Unhandled error has occured !!" & vbCrLf & vbCrLf & CType(e.ExceptionObject, Exception).Message & vbCrLf & _ErrorTitle & " will now close.", _
CType(MsgBoxStyle.OkOnly + MsgBoxStyle.Critical, MsgBoxStyle), _ErrorTitle)
WriteError(sender, CType(e.ExceptionObject, Exception), "No")
If Not System.Diagnostics.Debugger.IsAttached Then
Application.Exit()
End If
Catch
End Try
End Sub
And I've told you, this is not working only in .NET Framework 3.5 (after creating HTTPWebRequest object)
Right now I've switched my project to .NET Framework 4.0, and the same code is working perfectly

Seems you know what you are doing then.
I use HttpWebRequest a lot and never had such issues; I mostly use C# and .NET 2.0 though.
Maybe Google can tell you about some bug that got solved in 4.0?
|
|
|
|
|
I've tried to google that, but can't find anything ... Well, I'm just happy that my app now works  It could be that this doesn't happen in .NET 2.0 ether
Anyway, thanks for helping

Chr(0) is ASCII NULL you could also try Chr(8) which is a audio beep

Thanks for the reply
I tried chr(0) & Chr(8) both but it consumed paper , is there any why to move the Printer wheel/drum only but do not print anything

Chr(13) - carriage return. Used to be used to move printer head to left margin without feeding paper.
Don't know if it will work for your printer. Some printers had a DIP switch that could be set to allow them to interpret Chr(13) as Chr(13)+Chr(10) pair.
Or is it possible to just not send anything to the printer?
