.NET Program Being Detected As Virus On Remote System
Jan 3, 2012I've developed a simple program and in it I 'copy-pasted' some code which makes a copy of the program executable in a particular path (docs folder) and sets registry to start the executable in windows start-up only.. Everything is working absolutely fine in my PC. But when I sent the exe to my friend's PC. Then the antivirus in her PC detected it as a trojan!

VS 2010 - Install The Program - Errors Detected During Operation
Feb 10, 2011I've written my own program to assist other engineers with their work at my company. Some people have been able to install the program with no problems, others can't seem to get it installed and I'm having trouble figuring out why. They install .Net Framework 4 as this is the Target framework that was setup in the file, although I don't think I fully utilize all the features yet and not sure when I will. I will post the portion of the log that contains the error. If anyone decode some of this so I can track down the problem. I'm not sure if downgrading the necessary version of .Net would work or not, but didn't want to be changing that unless there was a good reason too.

WMI Network, VB 2008 Gets Invalid Function/invalid Cast Type
Jul 15, 2009I'm using WMI code and VB 2008 to see NIC status. So far the queries are working, but the methods aren't. For example, I'm trying to set a network card to use DHCP, I get invalid function with this code:
Dim classInstance As New ManagementObject("rootCIMV2", "Win32_NetworkAdapterConfiguration.Index='7'", Nothing)
Dim outParams As ManagementBaseObject = classInstance.InvokeMethod("EnableDHCP", Nothing, Nothing)
Handle Errors Caused By Invalid User Input In A Program?
Mar 10, 2011how do I handle the errors that may appear from the user of my program. For example, I have an triangle area program in wich I ask the user of the program to insert the length of the base and height of the triangle in a textbox. But what if he inserts a letter or something else, like a sign....my program will crash...
I know that one method would be to use On Error GoTo but I don't know how. If maybe you can direct me to some link or you could explain how do I handle errors, I would be grateful. Maybe you can even show me other ways to avoid errors from the user input.
This is my small program so far:

Getting An Invalid "Invalid Length For A Base-64 Char Array"?
Sep 9, 2011where I was encrypting the string and passing it to another web page to decrypt and get the ids to be displayed as a pdf back to the page. I kept getting an invalid "Invalid length for a Base-64 char array". It was then I realised that the string was getting truncated and that the IE Explorer had a size limit for the number of charaters being passes as a querystring.So I think I need to go the route of posting it.But not sure how to go about it.

Invalid Data Alert - Writing A Program That Has To Print An Alert Message In A Textbox?

ContextSwitchDeadlock Was Detected?
May 18, 2011I'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.

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, 2010This 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.

View 1 RepliesLoaderLock Error Detected?
Apr 20, 2009I'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.
Midi CallbackOnCollectedDelegate Detected?
Feb 23, 2012Hi to all, i really need some help with a piece of code. Im developing an app, which receive midi TIMECODE (MTC) and shows it on a textbox. when i start the app, it runs ok, and shows the mtc on the textbox, but after a few seconds it crashes and shows an error:
"A callback was made on a garbage collected delegate of type 'MidiTesting!MidiTesting.MidiIn_Callback::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called."

VB Applications Gets Detected As Virus?
Feb 25, 2009Then 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.

Mar 18, 2010New 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,
