The error happens in this line:
Dim imageMatrix = New Emgu.CV.Matrix(Of Double)(100, 120)
An unhandled exception of type 'System.TypeInitializationException' occurred in Emgu.CV.World.dll
CvInvoke.cvInitMatHeader(_ptr, _array.GetLength(0), _array.GetLength(1), CvInvoke.MakeType( CvInvoke.GetDepthType(typeof(TDepth)), 1), _dataHandle.AddrOfPinnedObject(), 0x7fffffff);
Is this a declaration or library error?
Thanks for your help
The possible reason for this 'System.TypeInitializationException' is that your project is not able to find all dlls from EMGU.Place all dlls(including opencv) from Emgu/bin/x64 or x86 into your project release/dubug folder . That will solve the problem.Setting environmental path variable for EMGU could also helps.

I have the following vb.net code:
Imports IBM.WMQ
[...]
MQEnvironment.Hostname = hostName
MQEnvironment.Port = portNumber
MQEnvironment.Channel = channelName
queueManager = New MQQueueManager(queueManagerName) ' error here
which is throwing the following error:
System.IO.FileNotFoundException occurred
FileName=C:\Users\User\Documents\Visual Studio 2012\Projects\[...]\bin\Debug\mqclient.ini
HResult=-2147024894
Message=Could not find file 'C:\Users\User\Documents\Visual Studio 2012\Projects\[...]\bin\Debug\mqclient.ini'.

I am not using any ini files in the construction of my queue manager, so does anyone have any idea what's going on - why is it even looking for one, and why in the same directory as the program? I have installed the MQ client, and afaik I have all the environmental variables, etc. set up properly.
Thanks for any help you can give
Is that an unhandled or a first chance exception? Internally, the MQ .net layer will try to read a MQClient.ini but should function quite happily without it. It reads the file for compatibility with the C client, and can handle some of the MQClient.ini stanzas. I would not have expected an absence of such a file to cause problems, but it will try to open it internally. Was that the full callstack, as I'd have expected some MQ libraries on the stack otherwise.
Using Visual Studio 2008 and generating .net 2.0 framework with VB.net for a web application.
I encountered a very strange problem currently. After I build a solution and click a link in a web page, I got an error message as following. The same thing happened when I tried to run in debug mode.
*************************************** ERROR Message ******************************************************
"An exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll but was not handled in user code"
"Additional information: Operator '=' is not defined for type 'DBNull' and string "". "
*******************************************************************************************************************
The problem part is simply as below in a vb file. The value of dataview(0)(“name”) is NULL and my_name is a variable string. The strange is thing I didn't change any code in this vb file. This vb file was built previously and used for a long time ago without any problem. It just suddenly happened today. I have this syntax all over the program without causing any problem. I have tried to restore the whole solution back to original but still have the problem.
Can anyone please advise why all the sudden and how to fix?
If dataview(0)(“name”) = my_name then …
Try to determine NULL value first ..
If NOT IsDBNull(dataview(0)(“name”)) Then
If dataview(0)(“name”) = my_name then
'codes here
End If
End If
I've been using DotNetZip for a month or so now and i like how it has worked but today my program started having a new issue that I'm clueless on.
During the zipping process it throws this error up and windows displays their "program name has stopped working" box.

Line 71 refers to where i call zip.save()
From your comments, I take that what happened is exactly what happened to me a while ago.
I was getting a list of files to zip and stored into memory. The I would go zipping them one by one until this exception was thrown. The cause was someone removed the file after I got the list, but before I got the opportunity to zip it. This occured on a shared folder, btw.
I have a VB.Net program written with .Net 2.0
I'm trying to write a code that logs entire registry entries into a log file.
I have got it to work wit the following code.
http://pastebin.com/kmA63cUe
However whenever I try to add an additional Registry key to log
LogPrint4("<-----------------HKLM/WebCheck-------------------->")
If reg.enumvalues(&H8000002, "Software\Microsoft\Windows\CurrentVersion\WebCheck", keys2, types) = 0 Then
If IsArray(keys2) Then
For p = 0 To UBound(keys2)
reg.getstringvalue(&H8000002, "Software\Microsoft\Windows\CurrentVersion\WebCheck", keys2(p), value)
LogPrint4(keys2(p) & "=" & value)
Next
End If
End If
It comes up with the following error
COMException was unhandled Check the ErrorCode Property of the
exception to determine the HRESULT returned by the COM object.
I'm not sure why it is limiting it only to 5 checks.
Anyone have any ideas?
Consider using the built-in Registry support instead of the COM libraries. At a minimum, you'll get clearer error messages. It is supported in .NET 2.0.

Good luck!
I have coded up a cleaner type of program but getting a huge error with permissions ( I think )
The error message is printed out like so.
An unhandled exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
Additional information: Access to the path 'C:\Windows\CSC\v2.0.6' is denied.
And it says that the error part of the code is this line
For Each fi In DirectroyInfos.GetFiles(filter)
But here is the fill block of code.
For Each fi In DirectroyInfos.GetFiles(filter)
Try
file_count = file_count + 1
file_size = CULng(file_size + fi.Length)
FilesToDelete.Add(fi.FullName)
Catch ex As UnauthorizedAccessException
'There's really no pretty way to handle this exception
Catch ex As FileNotFoundException
'There's really no pretty way to handle this exception
End Try
I think it's some sort of permission problem I have windows 7 and have noticed there are a lot of run has admin problems.. I think its trying to remove or gain access to a file which it does not have permission to get .
Is there anyway to fix this? Am I missing something in my coding?
As you said in your question, you don't have write access that file.
Either skip files you don't have access to, or run the application as admin.
There appears to be a limitiation with the win32 api that will skip all files in the folder if you do not have access to one of them.
