When I load up a XAML file in the designer I get the below exception and then I have to kill VS 2012 from the process manager. Any ideas on work arounds?

I know this one is a bit old but I had a similar problem in VS2013, found a clue from an MSDN article and checked the event viewer for exceptions, look for XDesProc.exe.
The problem was an out of date driver for my graphics card.
Once that was updated all started working again
It might help someone

I'm new to this site and I'm going to start immediately with a question.
Currently I'm working on a thesis but I'm a stuck at this moment. I've been asked to control an IP-camera via Beckhoff Twincat3. As this is based on visual studio, I thought it might be a good idea to start in visual basic to test and debug everything I code. Everything I do results in AccessViolation.
System.AccessViolationException was unhandled
HResult=-2147467261
Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I hope someone can get me back on track. If .ocx or other files needed, please do not hesitate to contact me.
I asked my teacher if he knew what was wrong and he came up with this :
In the program, I was working with an 'instance' of the activex-control. This resulted in a accessviolation. He fixed it by using the direct control.
After all it made sense. ;)

IT;S VB.NET not C# and i don't know how to exchange source from C# to VB.NET, THANKS
I want to get all paths from all running processes.
This is my source so far:
For Each p As Process In Process.GetProcesses
Try
ListBox1.Items.Add(p.MainModule.FileName.ToString)
Catch ex As Exception
RichTextBox1.Text = ex.Message
End Try
Next
But I can't get all path folders of the running processes.
If I examine the ex.Message, the response is like this
Unable to enumerate the process modules.
But if I not using ex.Message, the response is like this :
System.ComponentModel.Win32Exception was unhandled

Can anyone help me?
Take a look at the so-question How to get the full path of running process?
Instead of
ListBox1.Items.Add(p.MainModule.FileName.ToString)
try
ListBox1.Items.Add(p.Modules(0).FileName.ToString)
Edit:
Have you tried to evaluate the property of different processes directly? Maybe there is a certain process you cannot access, resulting in the error described.
You can try to iterate trough the processes one by one by creating the following loop:
For Each p As System.Diagnostics.Process In System.Diagnostics.Process.GetProcesses()
Try
Console.WriteLine(p.Modules(0).FileName)
Catch ex As Exception
Console.WriteLine(String.Format("{0}: Error - {1}", p.ProcessName, ex.Message))
End Try
Next
By doing so, you should be able to determine the processes you're not allowed to access and get a couple of processes you should be able to experiment with.
Mate the problem is obvious, you are targeting 32-bit but are testing your app on a computer that has 64-bit installed system, that's why you get the error.
Message=A 32 bit processes cannot access modules of a 64 bit process.
to fix this issue you should make the target 64-bit, there IS NO SOLUTION for this...
if you know the famous procexp (sysinternals) it has two separate application, when the system is 32-bit it lauches an instance of 32-bit, but when it is 64-bit it lauches another separate process for the system...
so if you want to deal with this issue, you have to make two instances for system compability,
Hope this is helpful

I am building a VB.NET desktop application in VS2013 that uses a .mdf file created in SQL Server 2012. I have the .mdf file imported in to the application. Along with the datagridviews I am using to view/modify the database tables I need to execute a SQL script when the user clicks on a button.
I have been trying several examples I've found, without any luck. I'm getting a FileLoadException error on the ExecuteNonQuery line:
An unhandled exception of type 'System.IO.FileLoadException' occurred
in mscorlib.dll
Additional information: Mixed mode assembly is built against version
'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime
without additional configuration information.
The "Troubleshooting tips" section has "Make sure that the file is a valid .NET Framework assembly". I clicked on that link, but the information there isn't very helpful to me, as I really am not understanding what it's saying.
I've tried these two examples so far:
Dim sqlScript As String = "C:\HL_Time_Entry_Reporting\SQL Scripts\stage_employee_hours_load.sql"
Dim connString As String = "Server=(LocalDB)\v11.0;Integrated Security=True;AttachDbFilename=C:\HL_Time_Entry_Reporting\Database\hours_analysis.mdf"
Dim connectionString As String = connString,
scriptText As String = sqlScript
Dim sqlConnection As New SqlConnection(connectionString)
Dim svrConnection As New ServerConnection(sqlConnection)
Dim server As New Server(svrConnection)
server.ConnectionContext.ExecuteNonQuery(scriptText)
from this site. And
Dim sqlConnectionString As String = "Server=(LocalDB)\v11.0;Integrated Security=True;AttachDbFilename=C:\HL_Time_Entry_Reporting\Database\hours_analysis.mdf"
Dim file As New FileInfo("C:\HL_Time_Entry_Reporting\SQL Scripts\stage_employee_hours_load.sql")
Dim script As String = file.OpenText().ReadToEnd()
Dim conn As New SqlConnection(sqlConnectionString)
Dim server As New Server(New ServerConnection(conn))
server.ConnectionContext.ExecuteNonQuery(script)
from this site.
One thing is, I'm not confident I have the correct connection string for this. That's the connection string I have for the datagridviews, which works fine, but is that also what I should use to connect for the sql script file as well?

It looks like you may be using an obsolete version of the SMO library, as explained here: https://stackoverflow.com/a/11286124/109122.
Update:
If the config setting recommended at the link does not work, try this simpler one instead:
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0"/>
</startup>
Unfortunately, it appears that the config file changes do not fix all cases.
I'm working on a directory Project where in when the program is not being use or idle for 3 minutes, a form that act as stand-by screen that plays a video will show (I use AxWindowsMediaPlayer). By clicking anywhere in the form, the stand-by screen will close and will be back to the main form.
The program works fine but SOMETIMES during the closing of stand-by screen form, the application crashes with the error:
AccessViolationException was unhandled. Attempted to read or write
protected memory. This is often an indication that other memory is
corrupt.
and this is the complete error detail:

InnerException:
The weird thing is, the line of code where the error is pointing, is enclosed in try catch block specifically catching AccessViolationException(it was exception before but still encountered the problem):
Private Sub tmrTime_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrTime.Tick
Try
lblTime.Text = TimeOfDay
If standby = 2 Then
standby += 1
standByScreen.ShowDialog() ---> this is where the error is pointing to
Else
standby += 1
End If
Catch ex As AccessViolationException
MessageBox.Show(ex.ToString)
End Try
End Sub
Please help me, thank you
This might be due to early binding of the standByScreen variable. Note that the error is caused due to the System.Windows.Forms class
Try:
Dim stndByScreen As Object
stndByScreen = standByScreen
stndByScreen.ShowDialog()
instead of directly using standByScreen
