It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

I'm working on a status monitoring program for my company and we need to be able to know if a process on a remote machine is hanging due to not responding (that I can do) or if it's thrown an unhandled exception. I've tried a number of things from checking the CPU usage of the process to checking if the process has gone idle. Nothing has really been reliable. Is there anyway to do this? All the programs we'll be monitoring are running on either .NET 3.5 or 4.0.

I keep getting a null reference exception w/this program, and its on the line that declares the array. I've looked it over and over and I just don't see why... Can you let me know if you see anything obvious? I'm also getting an "index out of range" exception, but it looks right to me...I declared everything with an 11 for 12 months, 0 to 11 for the intcount.

After dealing with the pain-in-the-____ error "The path is not on a legal form" witch only occured after dragging a file system watcher onto the form, by creating the file watcher in the code. When an event is raised, i have to tell the user what happened. I can do this using messageboxes, without any problem. But, when I wanted the output to be displayed in a textbox, the program terminates without any warning. Here is what my code looks like:
Public Class Form1
Public watchfolder As FileSystemWatcher
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have a form with binding sources and a method for saving the data.[code]I was testing to see what would happen if the operator tried entering duplicate data in the primary key field. They exception occurred as I expected but the program gets stuck at that point. The exception messagebox just keep redisplaying when you click OK. I'm fairly new to .Net, but this code is how the help files show updating a TableAdapter using the "Try/Catch".

I have a need to do the following can anyone give me an idea how it can be achieved? I have already done points 1 & 2, but I can't get point 3 to work:
1. VB9 app, accepts that accepts text input
2. When Submit is clicked, it copies the text to clipboard.
3. Then paste the text into a particular window that is already visible on an open wep page in Internet Explorer.
The window title of IE is for example
"Metastorm e-work client - Windows Internet Explorer"
I am trying to 'call' the already open page to make it appear over the VB application. The box I need to 'paste' into already has the focus, providing IE iteself has focus.

I'm doing a project using Microsoft Speech SDK 5.1 and I'm using Microsoft Visual Studio 2008 or VB .NET. I saw a sample program that came with Speech SDK 5.1 named "Dictation Pad" where he can make voice training come out. This app was made with C++ so I was wondering if I could do it also in VB. I would just want to create a button to press and then the training dialogue would come out. I really need it!

I made a Visual Basic program that adds an interface to some Windows network diagnostic tools like Ping and Telnet. Currently the program opens a new DOS window and displays the results. For each system you test or each time you hit the button it opens a new window.
What I want it to do is redirect the output back to the program and display it using a List box or whichever is the best choice for displaying results. I have checked out posts that talk about capturing the text and redirecting it back to the program but I can never get those to work.
Is there an easy answer for this or does it entail a lot of additional coding? I am using Visual Studio 2008.

When I insert CD, if program is already installed it should be run, instead of dialog box asking to remove/repair program. How to change bootstrapper, or maybe launch conditions, to run program instead of installing it over and over again?

I'm making a program from witch one could run an application with different credentials.I can compile the program successfully, but when I press the button to run the program I get the following error: Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.The system cannot find the specified file.The code behind the button is as follows:
Dim myProcess As System.Diagnostics.Process = New System.Diagnostics.Process()
myProcess.StartInfo.FileName = "c:
un.bat /user:kreathyr c:getlogin.exe"
myProcess.Start()
Getlogin.exe does nothing but show the logged in username and run.bat utilizes the runas command.
