Check If A .vbs Script Is Running Continue Code If .vbs Has Completed
Oct 7, 2011I have a spellcheck program for an external application. My vb.net app calls a .vbs file to invoke the word spellcheck engine, runs the spellcheck, copies to MS clipboard and then I want it to automatically paste back into the active window. What my issue is, is that I need a delay or check of some sort in the code so that I can know when the vbscript has been completed before pasting text to to the window. I've tried the following but the app invokes the script then immediately checks to see if the script is running (which of course it is) so it's useless... Or is this something I should change/handle in the vbs file? I'm not very good with vbscript however.

Exception Being Thrown In Designer-created Code Instead Of User Code
Sep 10, 2010In my project, I have a local dataset (XSD) that I am using as local-temporary tables. I am getting a System.InvalidCastException when trying to access the field in one the tables. I believe this is because I my code is (incorrectly) not setting a field's value in a row before trying to access it.My problem is that the exception is breaking in the designer file and not in my code. As a result, I'm having difficulting determining which line of my code reading the field value before it has been set. Is there any way to configure Visual Studio to break in my code instead of in the designer created file?
View 1 RepliesCatch An Exception And Throw A New Exception Which Wraps The First Exception As An Inner Exception
May 8, 2009It 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:

Code For Finding Factorials - Overflow Exception ?
Mar 30, 2011I have the following code for finding factorials:
Private Shared Function Factorial(ByVal Number As Long) As Long
If Number = 0 Then
Return 1
Else
Return Number * Factorial(Number - 1)
End If
End Function
It usually results in an overflow. It only works if I start with something small like 4. I have to work with starting numbers such as 30-60. I thought changing the value type to LONG would prevent this problem. This is VB.net just for reference.

Code Compiles, Throws Exception When Loading Project At Runtime?

Windows - Find Out Where In User Code An Internal .Net Exception Originated?
Feb 27, 2010I am currently working on an existing Windows Forms application (VB.net), and am busy reworking the exception handling mechanism.Currently, a lot of methods in the code are just surrounded with try/catch block that catches a generic exception and then calls a utility method that just shows the user a messagebox informing him of the error, and then logging it.So in a lot of cases no corrective action is taken and the exception is just logged. I know this probably isn't the best way but that's they way we're gonna have to do it for the near future.Anyway, I wanted to do this in a more generic way, so I hooked up Application.ThreadException and AppDomain.UnhandledException.
This seems to work well, except for one inconvenience. Whenever an error gets thrown from the .net runtime itself, or a 3rd party control, the stacktrace begins there where the exception is thrown in the framework-methods or 3rd party methods (obviously!)But it would be handier if I had an easy way of finding out exactly where these exceptions cross the boundary into my code. I would like an easy way of determining (in Application.ThreadException) where in my own code an exception originated. am aware this information is contained in the Exception.StackTrace property, but I would like an easy way to get to this specific information seeing as the stacktrace property is one huge string.
