System.InvalidCastException

Every time I update a file in the APP_CODE folder in asp.net I get the following error.
System.InvalidCastException: [A]TexasClass.TexasTest cannot be cast to [B]TexasClass.TexasTest. Type A originates from 'App_Code.w8xmcutn, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary
ASP.NET Files\root\15ae04a3\80f6a04b\App_Code.w8xmcutn.dll'. Type B originates from 'App_Code.dqtbd99q, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET
Files\root\15ae04a3\80f6a04b\App_Code.dqtbd99q.dll'. at ASP.admin_texesview_aspx.OpenExam(Byte[] bin)
The problem is a duplicate DLL is created when I update a code file. I can resolve it by restarting the server(I did that because I am not sure which file to delete).
Why is this happening and how can I avoid it?

CrystalReports 'System.InvalidCastException' occurred

Hi Team, I'm getting the below error. Can some one please assist me on this? I'm using Windows 2012 R2 server and CrystalReport Runtime 13.0.x version installed on the server. Application built on Any CPU using VisualStudio 2010 Error Message: HandlingInstanceID: c68a0e37-5eb5-4cb5-9587-6d6030b79b48 An exception of type 'System.InvalidCastException' occurred and was caught. --------------------------------------------------------------------------- 01/13/2015 16:26:11 Type : System.InvalidCastException, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Message : Unable to cast object of type 'FileStreamDeleteOnClose' to type 'System.IO.MemoryStream'.

Hi Don,
I gave this a try and I got the same results I was getting before the change the ExportToStream is returning a object of type FileStreamDeleteOnclose instead of an object of type IO.Stream.
You have what I had before already, but here is what I changed it to in order to do what the developer asked:
Protected Friend Function GetPDF(ByVal genColsolidatedPDF As String) As IO.
Stream
Dim exportStream As System.IO.Stream = GenerateReport(genColsolidatedPDF).ExportToStream(ExportFormatType
.PortableDocFormat)
Using fileStream As New IO.FileStream(expPath, System.IO.FileMode.Create, System.IO.FileAccess
.Write)exportStream.CopyTo(fileStream)fileStream.Dispose()
exportStream.Close()
Return
exportStream
End Function
Private Function GenerateReport(ByVal genConsolPDF As String) As
ReportDocument
Dim connInfo As New
ConnectionInfo
Dim databaseLoginInfo As New
TableLogOnInfos
Dim reportDoc As New
ReportDocument
Dim tableSet As
Tables
'reportDoc = New ActiveSignatures
reportDoc.Load(rptPath)
reportDoc.SetParameterValue(DAL.ParmName.MRId, BLL.SessionData
.EssInfo.MRID)reportDoc.SetParameterValue(cCONSOLIDATEPDF, genConsolPDF)
connInfo.ServerName = [Lib].ApplicationData.db_Server
connInfo.DatabaseName = [Lib].ApplicationData.db_Name
connInfo.UserID = [Lib].ApplicationData.db_UserId
connInfo.Password = [Lib].ApplicationData.db_Password
tableSet = reportDoc.Database.Tables
For Each singleTable As Table In
tableSet
Dim singleTableLogoninfo As TableLogOnInfo
= singleTable.LogOnInfo
singleTableLogoninfo.ConnectionInfo = connInfo
singleTable.ApplyLogOnInfo(singleTableLogoninfo)
Next
Return reportDoc
End Function
It seemed like the developer maybe wanted more information about how the report is then used, so this is what happens. The report is then supposed to be returned as type IO.Stream and then it is to be converted to an IO.MemoryStream:
Dim sourceFiles(sourceSize as MemoryStream)
sourceFiles(i) = New MemoryStream(GetByteArray(CType(parameters.SignaturePage, IO.MemoryStream)))
parameters.SignaturePage is the crytal report that is being returned, that is what needs to be IO.Stream, but is coming back as FileStreamDeleteOnclose.
When the application then tries to convert from FileStreamDeleteOnClose to IO.MemoryStream, that is where the error occurrs: Exception: System.InvalidCastException: Unable to cast object of type 'FileStreamDeleteOnClose' to type 'System.IO.MemoryStream'. But this is only occurring because I am getting back the incorrect object type from the ExportToStream call.
Before I upgraded to SP 13 this worked fine, and has been working fine for years. It is after SP13 that this ExportToStream stopped giving me the IO.Stream object type and is now returning the FileStreamDeleteOnClose.
I hope that helps!
Thank you,

System.InvalidCastException error

Hi,
I have a form with a matrix and an import button. Users can import records from a text file into a user defined table. After the import into table is complete, the form is refreshed with records from the table. It all works fine when there are only a few records. But if it takes longer to import, I get the following error multiple times during form refresh.
System.InvalidCastExcpet: QueryInterface for interfaceSAPbouiCOM.itemEvent failed at SAPbouiCOM.ItemEventClass.Get_FormUID
This happens even if the focus is on my form. If I switch to another application, I get this error even if the I import only a few records.
All the records get imported, the error is only during form refresh.
Can anybody help? Thanks in advance.
Thanks,
Aparna

Hi Gianluigi,
Sorry for not posting an update in the past month. I have been trying quite a few things to resolve this issue. I did try using the .Net Profiler but it was not of much use. The only message I get in the profiler is as follows:
Type: System.Runtime.InteropServices.COMException
Call: thrown
Type: System.InvalidCastException
Call: Thrown
I think the error is somehow related to UI API and window refresh. But I am not sure what it is. Interestingly, I get the error only while dealing with large data set.
Thanks,
Aparna

Chris,
I'm not a database guy - so in many ways, I'm not really qualified to answer this, but I'll make a suggestion anyway:
At the very top of your code, put the following:
Option Strict On
Option Explicit On
Option Infer Off
With strict on and infer off, it will force you declare types - which I see missing in many places in the code.
It's entirely possible that by you then going through and fixing those issues, you'll have corrected the problem.
I don't know that, but it's possible -- and it should be done this way anyway, so there's certainly no harm to be done; in fact you'll actually speed up the program to a small degree because objects don't have to be inferred for the type that they actually
are.
***** EDIT *****
Also this: DON'T declare any of the types simply as "Object"; that's just trading off late binding for boxing, so you haven't really done much good. Declare them each as their correct actual type.
Still lost in code, just at a little higher level.

How to overcome: System.InvalidCastException: Unable to cast object of type

Hi,
For the database connectivity, we use ODP.Net. In one of the functionality we are trying to bind an array to stored procedures and have it execute for the each iteration of the array as a bulk transaction.
Not always but, 10% of the times the function has raised the following exception
System.InvalidCastException: Unable to cast object of type 'System.DateTime[]' to type 'System.IConvertible' .
Has anyone ever faced such a problem, if someone has a soltuion it would be of great help to me.
Thanks

System.InvalidCastException at DataReader.GetInt64 or DataReader.GetInt16

Hallo,
we have an application which gets data from a view in an Oracle 9.2.0.7 database:
SELECT CAST (1138923 AS NUMBER (10)) AS object_id,
CAST (MIN.universal_time AS NUMBER (10)) AS universal_time,
MIN.local_time AS local_time, 0 AS mod_time, 0 AS COUNT,
CAST ((MIN.VALUE + MAX.VALUE) / 2 AS NUMBER (38, 19)) AS VALUE,
CAST (9 AS NUMBER (2)) AS flag
FROM TimeSeries
WHERE object_id = 1138923
We access this view with a ODP.NET 9.2.0.7 provider using a DataReader.
On our development machine and at the most customers the acces works very fine !!
But only at one customer we get an InvalidCastException iif we use the GetInt64 or GetInt16 DataReader method.
While debugging we recognized that the datareader method returns a decimal, although it is casted to number 10
We don't want to use a GetDecimal or CAST command in the .NET code, the view or table should return a double !
Is this a known behaviour ?
Many thanks in advance and
Best regards
George

How did you go about recreating the Managed Metadata Service Application? Did you point the service application at the existing database when recreating it or did you create it with a 'dummy' database and use the following PowerShell to point it at
the old database?
$app = Get-SPServiceApplication -Name "<ServiceApplicationName>"
Set-SPMetadataServiceApplication -Identity $app -DatabaseName "<DbName>"
Also, I have seen scenarios where the MMD service application db is completely corrupt and the only way to retain data is through the commands specified here:

Hi,
If you were running 5.1 version, that would also mean that you were running packages under SQL 2005.
And if you are now running SQL 2008 with BPC 7.0, you should also review all your customized packages. In fact, BPC tasks in SSIS are not the same between SQL 2005 and SQL 2008.
In addition, I would recommend to upgrade your SQL server version to SQL 2008 SP1 cumulative update package 6 (prerequisite). Not sure if you're still running this CU.
Hope this will help.
Best Regards,
Patrick

Unexpected InvalidCastException With DataTemplate

I have the following Xaml for which I set the ItemsSource property as follows:
<ItemsControl x:Name="itmRecipients" Grid.Column="0" Grid.Row="2" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollMode="Auto" ScrollViewer.BringIntoViewOnFocusChange="True">
<ItemsControl.ItemsPanel><ItemsPanelTemplate><StackPanel/></ItemsPanelTemplate></ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate><DataTemplate><RadioButton Style="{StaticResource BasicToggleButton}" GroupName="Recipients" Checked="Recipient_Checked" Content="{Binding Name}" Tag="{Binding Index}"/></DataTemplate></ItemsControl.ItemTemplate>
</ItemsControl>
Me.itmRecipients.ItemsSource = Me.Recipients.Select(Function(r, i) New With {.Name = r.Name, .Index = i})
As you can see, the DataTemplate is just a RadioButton which uses the Name and Index properties of the bound items. The bound items are an anonymous type with the properties Name and Index. But when I run the code, I get the following error:
A first chance exception of type 'System.InvalidCastException' occurred in GiftTrackerUnivAppTest_Windows.exe
After looking at App.g.i.vb, I found the following in unhandledExceptionArgs:
"System.InvalidCastException: Unable to cast object of type 'VB$AnonymousType_0`2[System.String,System.Int32]' to type 'Windows.UI.Xaml.Controls.RadioButton'.
at GiftTrackerUnivAppTest_Windows.MainPage.MainPage_Loaded(Object sender, RoutedEventArgs e)"
'VB$AnonymousType_0`2[System.String,System.Int32]' is obviously my anonymous type with the Name and Index properties. Why is it trying to convert my anonymous type to a RadioButton instead of applying it to the DataTemplate? Thanks.

Hi Nathan,
I used the following code snippet to test in store app, but I worked. I could not reproduce your problem. Can you post a repro project or post more information to explain your scenario?
Private Sub Page_Loaded(sender As Object, e As RoutedEventArgs)
list = New System.Collections.ObjectModel.ObservableCollection(Of Employee)()
Dim rnd As New Random()
For i As Integer = 0 To 99
Dim ee As New Employee()
ee.Name = "herro" & i.ToString()
ee.Index = rnd.Next(0, 101)
list.Add(ee)
Next
itmRecipients.ItemsSource = list.Where(Function(w) w.Index > 10).[Select](Function(s) New With { _
Key .Name = s.Name, _
Key .Index = s.Index _

DeltaSynchronization Error 29181 InvalidCastException

I started getting errors on the DeltaSynchronization but have not been able to determine the cause or who to fix it.
I have already increased the timeout values in ConfigService.config on all the management servers, although i didn't think this would resolve the issue.
Any help or suggestions would be appreciated.

Figured it out for my issue. A clustered server created additional windows computer objects with IsVirtualNode set to True, representing the cluster. It's an annoyance, but you need to know how to weed these out if your discovery will be run against Microsoft.Windows.Server.Computer
and where your SCOM box is monitoring clustered servers.
My discovery script tries to push the discovered object down to the agent. Which is impossible for these weird virtual computer objects.
    $global:discoveryData.AddInstance($instance)
    # force the seed down the the agent
    # To force the RMS to re-assign the local agent as the managing agent for the discovered physical server object ($instance)
    # we have to get a reference to the local health service class and then create a SPECIAL SECRET relationship :)
    $oHealthServiceInstance = $global:discoveryData.CreateClassInstance("$MPElement[Name='SC!Microsoft.SystemCenter.HealthService']$")
    $oHealthServiceInstance.AddProperty("$MPElement[Name='Windows!Microsoft.Windows.Computer']/PrincipalName$", $PrincipalName)
    $global:discoveryData.AddInstance($oHealthServiceInstance)
    $oHsCnRel = $global:discoveryData.CreateRelationshipInstance("$MPElement[Name='SC!Microsoft.SystemCenter.HealthServiceShouldManageEntity']$")
    $oHsCnRel.Source = $oHealthServiceInstance
    $oHsCnRel.Target = $instance
    $global:discoveryData.AddInstance($oHsCnRel)
It works find if all your servers are unclustered, but if they're clustered you can't push the object down to the agent, there isn't one. This seems to be the culprit of the call stack described at the beginning of this discussion.
So... to fix it (ignore the offending objects) ...
If you're doing a filtered registry discovery, add this to your filter expression...
      <Expression>
        <SimpleExpression>
          <ValueExpression>
            <Value Type="String">IsVirtualNode:$Target/Property[Type="Windows!Microsoft.Windows.Server.Computer"]/IsVirtualNode$</Value>
          </ValueExpression>
          <Operator>NotEqual</Operator>
          <ValueExpression>
            <Value Type="String">IsVirtualNode:True</Value>
          </ValueExpression>
        </SimpleExpression>
      </Expression>
The SCOM object returns NULL when the property is not True, so this is the best way to check (by prepending $Target with some token text like 'IsVirtualNode:')   The resulting generated text will be with 'IsVirtualNode:True' for the target objects
we want to ignore, and 'IsVirtualNode:' for the target objects we want to process (these are the non-virtual, real physical computers that you thought you were getting all along). If you do not prepend the $Target... with 'IsVirtualNode:' I've
seen SCOM not even process this with the expression evaluation, presumably because it's trying to compare a null instead of a generated string (which is what you get with my hack).
Ok, enough of that... If you're trying to do discovery with a script, you can do something like this, where you return early with an empty discovery payload otherwise proceed with normal discovery:
    $isvirtualnode = "IsVirtualNode:$Target/Property[Type="Windows!Microsoft.Windows.Server.Computer"]/IsVirtualNode$"
    if ($isvirtualnode -eq "IsVirtualNode:True")
        #Write-ErrorInfo "Tried to discover Active/Idle for $PrincipalName (IsVirtualNode: $isvirtualnode)"
        #return the empty payload back to SCOM
        $discoveryData
        return
    else
        #Write-Info "Tried to discover Active/Idle for $PrincipalName (IsVirtualNode: $isvirtualnode)"
    # proceed with normal discovery
Hope this helps someone out there. I spent a lot of time learning about how SCOM deals with clusters a few years back. It was quite a painful experience trying to develop a cluster-aware SCOM pack using the minimal white papers that were available.
This piece of info that I'm sharing took some digging as it wasn't documented well in the white papers.

Bitmap loading generates InvalidCastException

Hello all,
i'm on compact framework 2 (CLR Version: 2.0.7045.0), and i keep getting these first chance exceptions (disabled breaking on them) in my code when trying to load a bitmap from a file. However, the bitmap is created correctly.
I've seen it happen with both jpg and png, others i haven't tried yet.
Bitmap tmp;
tmp = new Bitmap(BackgroundImage);
or silimar ones all generate this.
A first chance exception of type 'System.InvalidCastException' occurred in System.Drawing.dll
The error is happening here:
System.Drawing.dll!Microsoft.AGL.Common.MISC.CreateMemoryStream(System.IO.Stream stream = {System.IO.FileStream}) + 0xb bytes
and detailed one is:
System.InvalidCastException occurred
Message="InvalidCastException"
StackTrace:
    at Microsoft.AGL.Common.MISC.CreateMemoryStream()
    at System.Drawing.Bitmap..ctor()
    at OctopusCF.UI.xml.SkinConfig.GetBackgroundImage()
    at Octopuscf.Program.Main()
Anyone have any idea where they come from? As the bitmap gets created correctly, could it be that something is happening internally in the system.drawing dll, from which it can recover and still load the bitmap?
Thanks,
Kristof

Yes. You should cache bitmaps you're going to reuse not just because of exception but mostly because it takes a long time to decompress bitmaps. Exception take may be 1-2% of that time. Watch out for available memory though, don’t cache too much.

InvalidCastException run an execution in WPF host

i got this error when I ran the execution in my WPF host.
An exception occurred inside of the call to .NET member 'CreateFromXmlFile': System.InvalidCastException: [A]TsDllCall.Person cannot be cast to [B]TsDllCall.Person. Type A originates from 'TsDllCall, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:xxx\Issues\TsDllHell\bin\Debug\TsDllCall.dll'.

The WPF host has loaded the TsDllCall.dll. The sequence loaded the DLL from another location. Both DLLs are identical. For a reason they have to be in different location. Somehow TestStand did not realize that the WPF host has loaded the DLL, instead it tried to load it from another location.
Any idea on how to solve this? I don't want to put them in GAC if possible.
Thanks.

TsDllHell.zip ‏69 KB

The WPF host is statically linked to the TsDllCall.dll and it uses 'new' operator to create the object. For the function call in the sequence file, it uses XmlSerializer to create the object. It gives no error if I use the 'new' operator to create the object.
I have created the event handler for AssemblyResolve. It requested the following assembly:
TsDllCall.XmlSerializers
TsDllCall.XmlSerializers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null
I have genarated the TsDllcall.XmlSerializers.dll using SGen and put it together with the 2 TsDllCall.dll. I load the one used by the sequence file in the event handler but I still get the same error. I'm not sure if I'm doing it correctly.
However, I have found another solution: http://sixlettervariable.blogspot.com/2007/05/net-xmlserializer-and.html
Place this in my app.config and the problem has gone.
<system.diagnostics>
<switches>
<add name="XmlSerialization.Compilation" value="4" />
</switches>
</system.diagnostics>
I don't know what is it doing exactly. I will use this solution for now.
Thanks for the help.

I am writthing a simple illustrator CS5 VB application for testing in VS2012 on Windows7 64-bit. The application can be built succesfully, but got an error at line 2- InvalidCastException occurred. Return argument has an invalid type.
line 1 - Dim appref As Illustrator.Application = New Illustrator.Application
line 2 - Dim myDoc As Illustrator.Document = appref.ActiveDocument
The detailed errror is
System.InvalidCastException occurred
HResult=-2147467262
Message=Return argument has an invalid type.
Source=mscorlib
StackTrace:
at System.Runtime.Remoting.Proxies.RealProxy.ValidateReturnArg(Object arg, Type paramType)
at System.Runtime.Remoting.Proxies.RealProxy.PropagateOutParameters(IMessage msg, Object[] outArgs, Object returnValue)...................
But similar code works in word 2007 macro, so reference to illustrator CS5 is fine. I think it is caused by .NET Framework 4. Where should I start to solve the problem? Any help is appreciated. Thanks!

Hello,
I am getting the same error and I found some articles on Oracle Metalink (Note 360287.1) regarding the filesystemio_options parameter and the mount option cio. Basically it looks as if AIX will not allow another program e.g. cp to access the oracle datafile whilst oracle is accessing it unless you have set the cio option at the filesystem level.
I haven't tried this yet as I need to get some downtime but I think this is what is causing the problem.
Be careful if you don't have the Oracle datafiles in seperate filesystems because there is a problem with cio and running binaries. (check the man pages for the cio mount option)
Hope this helps you.
Regards
Garry Bayford.

Exchange Web Services (EWS) - InvalidCastException

I have a service that reads the new emails in an Office 365 Exchange mailbox, and saves attachments in a directory.
For most emails it runs well, however I'm getting a lot of the following exceptions lately:
System.InvalidCastException: Unable to cast object of type 'Microsoft.Exchange.WebServices.Data.ItemAttachment' to type 'Microsoft.Exchange.WebServices.Data.FileAttachment'
I will post a piece of my code, could anyone please have a look and tell me what I need to change? It's .NET 4.0, Visual Studio 2010, Visual Basic and the latest Exchange Web Services api, 2.2.
Dim sf As SearchFilter = New SearchFilter.SearchFilterCollection(LogicalOperator.And, New SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, False))
Dim findResults As FindItemsResults(Of Item) = service.FindItems(WellKnownFolderName.Inbox, sf, New ItemView(128))
If findResults.Count > 0 Then
Dim items As ServiceResponseCollection(Of GetItemResponse) =
service.BindToItems(findResults.Select(Function(item) item.Id),
New PropertySet(BasePropertySet.FirstClassProperties, EmailMessageSchema.From, EmailMessageSchema.Sender, EmailMessageSchema.ToRecipients, EmailMessageSchema.IsRead))
For Each itItem As Microsoft.Exchange.WebServices.Data.Item In findResults.Items
If TypeOf itItem Is EmailMessage Then
Dim mailItem As EmailMessage = DirectCast(itItem, EmailMessage)
If itItem.HasAttachments Then
itItem.Load()
For Each Attachment In itItem.Attachments
If TypeOf Attachment Is FileAttachment Then
Dim fa As FileAttachment = itItem.Attachments(0)
pathAttachment = "c:\temp\" & fa.name 'not actual code, but to make this code readable and to the point
Try
fa.Load(pathAttachment) 'save file

It looks like you've hardcoded to always access the first attachment, when really you want to access the current attachment in the For Each loop. (Unless my VB skills are rusty, which is definitely possible!)
Dim fa As FileAttachment = itItem.Attachments(0)
