ContextSwitchDeadlock Was Detected?

May 18, 2011

I'm getting this message in my 2010 debugger suddenly for some reason:The CLR has been unable to transition from COM context 0x4c4b68 to COM context 0x4c4cd8 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.

It happens while I am looping through a datatable. In each iteration I do a SQL Select lookup and a a SQL Update if I don't find a matching record.

For Each drCurrentRow As DataRow In m_Dataset.Tables("Group").Rows
Dim boolFound As Boolean = False
CheckForRecordInTemp(boolFound, drCurrentRow.Item("ACTIVITY_GROUP"))

FileSystemWatcher Doesn't Activate - Error: ContextSwitchDeadlock

Mar 30, 2010

I'm using VB .Net 2008. I have been experiencing a wierd problem with my FileSystemWatcher that I haven't been able to resolve for the past few days. The watcher only catches the first event. The watcher is enabled via EnableRaisingEvents. I'm not sure why it quits. I was getting an ContextSwitchDeadlock error, so I placed <MTAThread> before the sub to switch to multiple threading. The errors stopped, but the FileSystemWatcher doesn't activate after the first event. Has anyone experienced this before? How do I fix this? [Code]

Edit and Possible Solution: Based on the answer at DisconnectedContext MDA when calling WMI functions in single-threaded application I think the solution here is to call GetPortName() outside of WndProc. I will test this tonight and post my result.

Error - InvalidApartmentStateChange Was Detected

May 5, 2010

This is the message that I'm getting out of a program I'm writing.

InvalidApartmentStateChange was detected

Message: The current thread used to have an apartment state of MTA, but the application has CoUnitialized this thread and it is now STA. This may cause calls on RuntimeCallableWrappers representing some COM components to fail and may also cause COM component that are not multi-threaded to be accessed from multiple threads at the same time which can cause corruption or data loss.The current program structure is UI buttons that activate a BackGroundWorker object to do the processing and display progress in a progressBar.The only thing I seem to have added (as in I disable the code and it works fine) is code to print two reports.To sum up, I'm in the backgroundWorker thread, and I kick off an event "PrinterDoc1.Print()" which I've handled (there doesn't seem to be much flexibility on using an event for that), then later on in the backgroundWorker thread this error shows up pointing to the invocation of a delegate which updates a label on my form.

LoaderLock Error Detected?

Apr 20, 2009

I'm using an AutoDesk Inventor View API (dont think it matters for this question) placed on my form. I can call files and have them open without issue, only when I open assemblies (drawing files) I get this error:

"LoaderLock was : Attempting managed execution inside OS Loader Lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang."

I dont expect anyone to know much about the API, however I assume this is a common error.

VB Applications Gets Detected As Virus?

Feb 25, 2009

Then i downloaded C4F (Code 4 Fun) an application that's allow you to make Peer2Peer Applications using the PNRP.

So then i made a simple chat (Must say you do not need to fill in any code at all for this chat system) then i compile the source code to an *.exe file and everything seems fine at this stage.

But now the problem accours, when im am sending my chat application to my friends they got an alert about it's a virus im sending them. but when the file is on my own system it dosent say anything at all, and i have AVG Pro Edition & OutPost Firewall 2009 with lifetime license. and all my Anti Virus / Spyware Engine is up to date.

I have been writing on another forum on the internet but they just told me that my system was infected with a virus and that was the problem. s� ive completely deleted my whole system, and installed the Windows XP Professionel again.

But i i stil have the same problem? any one knows whats going on here. i cant post anycode for this cause you don't need any code for making a Chat application in C4F, Basicly it loads a C4F project in to Visual Basic Studio 2008 with no source at all.

VS 2008 RaceOnRCWCleanup Was Detected?

Mar 18, 2010

New one on me. RaceOnRCWCleanup was detected happens when I close my application. The complete error was:"RaceOnRCWCleanup was detected Message: An attempt has been made to free an RCW that is in use. The RCW is in use on the active thread or another thread. Attempting to free an in-use RCW can cause corruption or data loss."

I found a link for the error here[URL]...34(VS.80).aspx . That either went screaming over my head, or it is like listening to politicians, a lot of words that don't mean much.

My best guess is that I added a WMI query that runs periodically in a background thread, thinking that because it was a background thread I had nothing to worry about. I added some code to close the background thread before the application closes and so far,

Cross Thread Operation Detected

I am trying to load data using a backgroundworker using a code snippet that I found. I think that it would all work fine, except that I am getting an error that I am doing a cross thread operation. The task that I am trying to accomplish is loading data for a large dataset when a command (Run Operation) is called so that I can prepare the user that it may take a long time, and I can display a scrolling marque to show them that the program is not frozen. I am using a separate form to display the warning, an OK button, and a scrolling marque.[code]
