Hello every one
I am developing a application in VB 2005
I am using On Error Goto to handle errors.
Now my issue is that I want to handle different type of errors in a function separately.
That is like
Do some thing if the database connection is not there
Do some thing else if the data is not found
And so on
I am not able to identify the errors in that way.. I am able to displaying the error number and description provided by the error object.
Is there any way to find out or a list of error numbers available?

Why are you using On Error Goto with VB.NET? This is a throwback to the bad old days of classic VB and should be avoided like the plague. Structured error handling was introduced in VB.NET with try...catch...finally blocks. Have a look at this article[^]. You can set up multiple catch blocks for a try block to catch different types of errors.

You should really go away from On Error... and instead use try/catch blocks as the other poster suggested.

thanks every one for the reply..
I got rid of ON ERROR GOTO and finally have try and catch...

At a guess I would think it's something to do with the change from Managed C++ in 2003 to C++/CLI in 2005. I've not used MC++ or C++/CLI but I do know that there is an explicit difference in syntax between pointers and references in C++/CLI but in MC++ there isn't. Is it possible for you to upgrade the MC++ to C++/CLI and then try again? Though in theory backward compatibility should be preserved. Knowing MS there's probably some compiler switch you have to set.
If you don't get any joy in this forum you might try posting on the MSDN Forums. MS developers tend to pop up on there periodically.

Is the Byte* pointing to an array?
If so, can you change the method to something like
array<Byte> ^some_method();
and have the method create and return an array<Byte>^?

I have a Windows service that has an installer class. I set the StartType to ServiceStartMode.Automatic, but after installation, it doesn't automatically start. What didn't I do?
BTW, the service starts fine if I do it in the SCM.
EDIT: I added the following code, and it works great:
class CLFCSServiceInstaller : ServiceInstaller
{
public override void Commit(System.Collections.IDictionary savedState)
{
base.Commit(savedState);
ServiceController controller = new ServiceController(this.ServiceName);
controller.Start();
controller.Close();
}
}

I'm creating a spy and packaging it in a COM library.
It is to be used by vbscripts for testing purposes.
I am able to search through the child windows of a window to find controls that already have a caption (i.e. buttons, checkboxes, radiobuttons.) using FindWindowEx(...).
How would I be able to retrieve the handleID (HWND) of a control based on it's Name?
(i.e. textbox1, ListView1, TreeView1, etc.)
I appreciate the assistance,
Cheers,

I think you can use "control.Handle" Or Textbox.Handle property to get the HWD.

Hi
I am trying to compile a website optimized for x64 processor architecture, however it does not work. I have selected x64 as primary platform on project options but whenever I try to debug my code, it gives that silly " Attempted to load a 64-bit assembly on a 32-bit platform. Use ReflectionOnlyLoad() instead if trying to load for reflection purposes. " error. What should I do?
Your help would be greatly appreciated

I think the error speaks for itself. You're trying to run 64-bit code on a 32-bit machine. That isn't going to work. In order to debug the code, you need to either set the project back to targeting a 32-bit machine, or move your development (Windows, Visual Studio, ...) to a 64-bit machine.

I have vista enterprise 64 bit installed on my pc. Morevoer .net framework 3.5 (x64) is also available. I am using .net 2008 rtm on this machine and still getting this error. What do I miss ?

I don't have any 64-bit machines, so there's really nothing I can test.
But, from the sounds of the error message, Visual Studio is running in 32-bit mode. And after about 5 seconds of Googling, I found this[^].
|
|
|
|
|
It seems that vs tries to use 32 bit framework by default. I have to change this setting by using Microsoft.NET\Framework64\v2.0.50727\installutil.exe command. Your reference link really helps out.
I really thank you for your attention,
Sincerely

Hello,
My .NET application locks up when the screensaver starts. I have no idea why or how to "debug" this.
Found no answer on google/msdn forums.
Hope someone can help me out ( any reason or way to debug this)
Regards,
Andy

It's probably more likely that your app hasn't actually "locked up" but that the screen saver has consumed 99%+ of the CPU, causing all other processes to run so slowly that they appear to lock up. The solution to that is simple - either don't run the screen saver or run a simple one, such as the Default or Logon Screensaver. Running any of the standard "3D" screen savers will eat nearly 100% of the CPU.
|
|
|
|
|
That would do it all right.
|
|
|
|
|
Thanks for the help but It's not right in my case, all other applications stay *alive* when the screensaver goes off, except my .NET application.
I've tried google, it seems like many more people have this problem and not 1 solution was ever posted!
The program does not go into unresponsive mode, it behaves more like when you try clicking a form when theres a Dialog window active.

There's nothing known in the .NET CLR that does this. I'd try the ANTS profiler on the code and see where it's hanging up.

Hi,
You can't develop/debug a 1.1 app with Visual Studio 2005.
you can have several .NET Framework versions installed side-by-side; they don't interfere
with each other.
and you can have several Visual Studio versions installed side-by-side; they don't interfere
with each other.
But a .NET 1.1 app needs the 1.1 framework (and Visual 2003 to develop/debug).
And a .NET 2.0 app needs the 2.0 framework (and Visual 2005 to develop/debug).
There is a tiny little glitch: whatever Visual version you install last is the one that
will open automatically when you double-click one of the associated file types (either
source files, project files, solution files).

I would go one further...

Yeah, that's a pain. I'm curious....after working with 2008, the solution icons
(when seen in Windows Explorer) have the VS version on them (like - "7.1" for 2003,
"8" for 2005, and "9" for 2008. Were those there in 2005 too?
Happy Holidays!
