Build Failed - No Reason Or Exception Thrown
Nov 17, 2010
Last night my project worked just fine. I left my system up overnight and came in this morning - my project is still on the screen, so there was no update/reboot or any of that. I added 6 lines of code, and suddenly get Build Failed. I removed those lines of code, and still get Build Failed. I restarted Visual Studio, and still get Build Failed. No Exception is ever thrown and no cause for a failed build is ever given. Output is set to Diagnostic, and it indicates nothing wrong or out of the ordinary - every task completes successfully right up to the end when it says Build Failed.

This may be a debugger issue, but here goes:I have this piece of code:
Private Function Connect() As Boolean
Try
sessionBegun = False[code].....
My intention is to 'convert' the low level exception into something more meaningful, so I throw an exception of my own creation. I want this to bubble up to a place where I can handle it.However what is happening is my debugger breaks and tells me that an exception of type "QuickBooksConnectionException" was thrown.I know that, I just threw it, why are you catching it? From what I've read, this ought to work, and there doesn't appear to be an analogous Java throws keyword, so perhaps it is my debugger.

A particular VB.NET project is actually throwing 'Build Failed' But when I try rebuilding again it says 'Rebuild Succeeded'. It keeps alternating this behavior. Kind of random. Any vbc.exe issue of long locking the PDB or xml files?

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'm working on an application that contains a "BackgroundWorker", the "BackgroundWorker" worked fine but after I started to change some stuff it gives me an error ("Exception has been thrown by the target of an invocation.")... I used a breakpoint to see where it happens, the exception gets thrown at the "End Sub" line of the BackgroundWorker.I then deleted all the code inside of it and ran it again.I still get the error.

What is the meaning of this error message?
"Exception has been thrown by the target of an invocation"
Instead of words, here is my code's logic :
while loop
run BGworker01
run BGworker02
...
run BGworker09
application.doEvents
thread.sleep(10)
end while
All the bgWorkers do the same thing (sending some data, only to different locations). When I run this loop with only 1 Background-Worker, it's all fine, but when I add the other bgWorkers i get the mentioned error at the "application.doEvents" part of the loop. I think it also points to another place (highlighted in green) inside one of the bgworker's code :
Dim FileStreamToSend As FileStream = New FileStream(fileToSend, FileMode.Open)
I thought it might be a problem that all bgWorkers are trying to read from the same file together, but when I tried using different file for each bgWorker, the problem persisted.

I know this is a relatively common error but I am working in an application that allows custom reports to be written using vb.net or C# for scripting. Error handling is very poor and I am not knowledgable enough to add my own (if it is even possible).
My code simply retrieves a value that is stored in a textbox on the report formatted as LastName, FirstName and truncates all characters after the comma. This value LastName is placed in a new textbox on the report. Here is my code:
Sub Detail1_Format
Dim lastNameFirstName As String = ""
Dim lastName As String = ""
[Code]....
The error happens when I use lastNameCommaIndex to set the number of characters in my substring. If I replace it with a number the report is published properly.

I'm working on a project for school in which a dll is loaded.
The dll that is loaded is a bridge between my program and the Twincat System Manager which forms the bridge between the computer and a PLC via the local network.
I need to read Variables trough this whole chain from the plc to my program.
This is the way I do this:
Public Function adsReadReal(ByVal Variabelenaam As String) As Single
Dim ds = New TwinCAT.Ads.AdsStream(4 * 8) ' new data stream
Dim br = New System.IO.BinaryReader(ds) 'new binary

I am writing a windows service that needs to be running 24/7. It is a pretty simple service that monitors a directory where files are dropped into and processes those files. I need to restart the service if an unhandled exception is thrown.
Is there a way for a service to restart itself in the event of an unhandled exception?

I want to force a calling method to implement exception handling.
Java forces a calling method to implement exception handling where it calls another method that thorws an exception.
Does VB.Net have the same mechanism?

Weird problem, it only happens for one of my clients, and it happens on all 3 of their computers. Their computers are Windows XP.My form has a Windows Media Player control on it, to play a video from the internet. When the form loads, I get an exception "External component has thrown an exception". It happens in the form's designer, in the InitializeComponent procedure, at this line:CType(Me.wmpVideo, System.ComponentModel.ISupportInitialize).EndInit()
It works great on 100 other clients computers, running XP, Vista, or 7, and this is the first person to have this issue. If I take the Windows media player out of the form, it works fine.BTW, those computers have Windows Media Player installed, I already checked.

I have a winform where I have some controls like TabPane, Label, ....When I launch my application without localization, it works fine. When I put localizable parameter True, I have this error :
TargetInvocationException was unhandled
Exception has been thrown by the target of an invocation.And when I debug my application, I follow the execution, program begins executing InitiliazeComponent(). I press F11 to continue the debug, program executes the TabIndex event of my TabPane and on the first instruction it crashes.My environment is VS2008, Framework 3.5. I store my project on a network hardisk (I test on local and it doesn't work too)

I'm relatively new to VB.NET and am having a problem when Databinding a Class to a Forms Controls. Basically within the Class, when Setting certain String Properties I heck that they are not Null/Empty and if they are Throw an Exception. The problem occurs when I bind the properties to textboxes - when the textbox is empty I expect an error to occur (which I will handle). So does anyone have any insight or solutions into why the exceptions are not being thrown when a textbox changed to an empty string?
A condensed example follows:
Dim a As New SomeClass("Random", "Text")
Dim f As New SomeForm(a)

I'm prompted with this error 'Exception of type 'System.OutOfMemoryException' was thrown' it was thrown when filling a dataset with 400,000+ records. And I think obviously is about memory matter because of the number of records to be transfer.My program goes this way.. after filling a dataset from a table it will transfer all data into another table. Now my question is, Is it possible in vb.net that while filling a dataset it transfers the record immediately into another table? Please give me an idea on how to do this.

The exception message I am receiving is this... "Year, Month, and Day parameters describe an un-representable DateTime."
Now I've traced my values being passed and everything is correct. Values loops through 1 to 12 but still I continue to receive an exception. Only way I can avoid this is by throwing a Try, Catch statement around where I'm passing over the value.
Here's my code..
001 Dim Calendar(11) As AppointmentBookControl.AppointmentBookControlMonthlyOverviewCalendarControl
002
[Code]....
Line '011 .Month = i+1' is where the problem is located. The values for (i+1) maintain within the bounds of 1 through 12..
