I am trying to search the C: drive for all files with a certain extension. I am using the following code which is working fine, however when it encounters an error the whole process stops rather than continuing with the scan. (running in backgroundworker, hence the invoke)
Private Sub ScanFiles(ByVal rootFolder As String, ByVal fileExtension As String)
'Determine if the current folder contains any sub folders
Dim subFolders() As String = System.IO.Directory.GetDirectories(rootFolder)

What i want this to do is Auto-Find a server application on the local network that has opened a TCP port (Say, 6473) Then tell the user the IP address that it's on. I have searched for hours, but to no avail. How would I accomplish this?
When the right box appears on the screen (not an image/popup/msgbox but build-in another .swf file), I want to get a MsgBox with You Won!. And if the wrong box appears, you get a MsgBox with Better luck next time!. I have a picture of the 'right box' that is located in resources (rightbox.bmp) and also in PictureBox1.

I am trying to make a program that when run changes the <title> attribute of the HTML, on any page requested then loads the page (IE). Is this possible, without making a new browser? If so, how?
I have a solution with two projects. The main project connects to the second project via a reference, and the reference path is local to my machine. It looks like it references the .exe file.So when I publish the main project (ClickOnce), i get the following error: Application validation did not succeed. Unable to continue.In the log file, under Error Details, it says
System.Deployment.Application.InvalidDeploymentException (RefDefValidation) - Reference in the manifest does not match the identity of the download assembly Project2.exe - Source: System.Deployment
How can I include this second project? Should I publish it, then reference the published files? What do i reference? The .application file?Is there a way to just include this second project, so when I do publish the main project, the second one just goes along with it?
How do I continue to print a list onto another page once the bottom of the page is reached?
Dim PrintFont As New Font("Arial", 14) Dim HeadingFont As New Font("Arial", 14, FontStyle.Bold) Dim LineHeightSingle As Single = PrintFont.GetHeight + 2
It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:
I have a FolderBrowserDialog box, and when the user selects a folder, I would like to scan that folder and its sub folders for these file types: jpg, gif, png Here is what I have so far:
I was doing my project and came across an error (The I/O operation has been aborted because of either a thread exit or an application request) regarding this

I'm writing a program that's supposed to keep the employees at my work away from doing things they're not supposed to on the computer. So I made a "launcher" window that's only closeable with password. I also disabled task manager. However when I start an application from my launcher window, the launcher window goes over it because of its topmost property.

I have a class library that is referenced by several other class libraries along with the main program. About two weeks back, I made a change to one of the classes in that base library, which is used as an argument for some events. Since that time, I have been testing code. Today, after a couple more tests, I started getting this exception. It is indicating a field is missing, which was renamed in that change about two weeks ago. The exact code that is raising the exception is code that I have run a couple dozen times in the intervening time, and it has always worked.I have tried everything I can think of, including deleting the bin and obj folders of every module that could be in any way related to this issue, such that the whole thing was rebuilt. I have removed the references and re-added them. Nothing worked. Code that has run fine for weeks has decided that it wants a version of an object that has not existed for weeks.
This problem arose immediately after a different problem, so the two might well be related. The other problem was that, while stepping through code, the IDE decided that one of the code pages was different from when it was last loaded. I get that a fair amount, and solving it is fairly routine. It generally means that I am stepping through code in a dll, and inadvertently tried to fix a bug in that code, rather than in the dll itself. Now it no longer matters. I can't get to that code page, nor can I get to anything else in that dll. It is acting like it has sponaneously decided to revert two weeks back in time, and use that source code for debugging, despite any attempt I make to bring it up to modern times.
im making a program and it needs to load 95 files on form load.im trying to make it to if the file cant be found that it will give a error instead of a JIT debug thing. i triedadding

I am getting this warning after I have changed the computer. I just installed framework and visual basic 2010, trying to edit the application that I been working on and one of the main forms is giving me this error. Warning 1 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)) 0 0
I developed an app, tested on few computers and all seemed fine. But now, some people suddenly get an error, which I can't repeat on my computers. Part of the exception:
** Exception Text ** System.TypeInitializationException: The type initializer for 'NumoABC.functionsBurtuSummas' threw an exception. ---> System.InvalidOperationException: The form referred to itself during construction from a default instance, which led to infinite recursion. Within the Form's constructor refer to the form using 'Me.' at NumoABC.My.MyProject.MyForms.Create__Instance__[T](T Instance) in 17d14f5c-a337-4978-8281-53493378c1071.vb:line 180 at NumoABC.My.MyProject.MyForms.get_MainForm() [Code] .....
The If Me.Created = False Then is because while the form is loading, some events fire the updatePersonDataHandlers() sub, but I don't want it to happen until form is fully loaded. In the module functionsBurtuSummas line 2 Module functionsBurtuSummas Private f As MainForm = MainForm I have many modules who work with the MainForms' controls, so I use a private variable f to refer to the MainForm.
Im am trying to get two separate applications to communicate with one another via a txt file. The first application writes to a txt file every even second and the second application reads the text file every odd second. The problem is Im getting an exception saying The process cannot access the file FILE_PATH.txt' because it is being used by another process. Not sure if my code is correct or not? Or if there is a better way to do this?
Weird problem, it only happens for one of my clients, and it happens on all 3 of their computers. Their computers are Windows XP.My form has a Windows Media Player control on it, to play a video from the internet. When the form loads, I get an exception "External component has thrown an exception". It happens in the form's designer, in the InitializeComponent procedure, at this line:CType(Me.wmpVideo, System.ComponentModel.ISupportInitialize).EndInit()
It works great on 100 other clients computers, running XP, Vista, or 7, and this is the first person to have this issue. If I take the Windows media player out of the form, it works fine.BTW, those computers have Windows Media Player installed, I already checked.

I have a simple form that when filled out with a case # will return the name of the person that is handling the case. I am getting an error on any machine that does not have VS 2010 installed on it. The error is when ever the user uses the close button (the red X) at the top right of the form the following error is generated:
System.InvalidOperationException: Collection was modified; enumeration operation may not execute. at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)
I have exactly same problem as guy at [URL] . Quote: I'm using multithread in my application. in each thread, launch a form which has a webbrowser. each browser is controlled by another thread to test some sites. however, sometimes, it has some access violation exception. these exceptions are not beause of cross thread issue since all processing for the browser are using delegate. And the problem is: I can not catch the access violation exception.
