My application creates a file by writing to System.AppDomain.CurrentDomain.BaseDirectory() & "data/" & filename...Now this works fine usually, but I just added a setup utility to the app, so now it installs to the program files directory. It installs correctly and creates the data folder, however when it tries to write the file it gets an exception "unauthorized access".

I have one user that is having a problem with my application, the error report shows an event type of clr203r and an index out of range exception. From what I've read this seems to have "something" to do with arrays or lists. (What that something is, so far, is beyond me or anything I've researched). I do have one array in my program -- myarray(13) as byte and I do have the syntax right as far as noting 20 elements in it. in my other bits of code.
I'm reading those bytes in the serial port, deciphering them and performing some actions. (to be vague). But just with what I've said, can anyone point me to a possible problem? Is the index out of range exception ALWAYS concerned with just arrays or lists? Or could it be something else?

View 2 RepliesI'm handling the Application.UnhandledException event in a WinForms app and need to log exceptions caught there. My app.config is set up to log exceptions to a FileLog and an EventLog.The problem is that when running as a non-admin user, the EventLog cannot be written to because of a SecurityException - I get the message "The source was not found, but some or all event logs could not be searched."I understand why - the user does not have permission to create the EventLog source, but the question is how should this source be created? As I see it, I could either:
1) Create the EventLog source with my installer, as this is running as admin. How to do this?
2) Create from within my app, by somehow elevating permissions? But this would give the UAC prompt on Vista.
What's the best practice for creating a Windows Application EventLog source on a client machine?
I am learning visual basic. I have created a form for a calculator. I have placed buttons for plus, minus, division, multiply etc. The programme is working for clicing on buttons i.e. when I want to add two nos. I accept 1st no. from text box then I click on "PLUS" button then I accept 2nd no. When I click on "Equal" button the result is displaying on textbox. But I want to write code insted of clicking on "PLUS" button if press " + " key on keyboard and for "Equal" button, if I press " Enter " key on keyboard, The result for adding two number should display on textbox. I want code for both click event and keypress event.
View 2 RepliesI have a service application that randomly stops without any errors in my log or in the event application log. I believe that there could be an unhandled exception somewhere in the code so I set up the AppDomain.Unhandled event to catch any exceptions. While trying to induce unhandled exceptions I have found that this event is not always fired. I added the following code to my service's Shared Sub Main method (but I orginally had it in the OnStart method and was seeing mostly the same thing)
Dim currentDomain as AppDomain = AppDomain.CurrentDomain
Add Handler currentDomain.UnhandledException, Address of MyHandler
How can I catch an exception thrown by a control event?I have a control that throws an exception in one of its events and I need to catch it but I don't know how.Consider for example that the text box control throws an exception in its click event. How can I catch such exception?
View 3 RepliesA developer has created a custom control in ASP.NET using VB.NET. The custom control uses a repeater. In certain scenarios, the rpt_ItemDataBound event is encountering a data error. My goal is rather than having the user see the yellow screen of death, give the user a friendlier error explaining exactly what the data error is. I figured I would be able to use a Try/Catch block as shown below throw the exception, however, it appears that the event has nowhere to be thrown to and stops executing at the "End Try" line.
Protected Sub rpt_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rpt1.ItemDataBound, rpt2.ItemDataBound
Try
ProcessBadData...
Catch ex As Exception
Throw ex
End Try
End Sub
In VB.NET, I can find where the repeater's DataSource is being set, however, I can not find a DataBind event. How I can capture the exception in this ASCX control so I can report it to the user. The stack trace looks like this. There is another repeater within the repeater that is actually causing the error (rptOther) and I'm able to catch the error, but I can only throw it to the rpt_ItemDataBound. How rpt_ItemDataBound is getting called without a DataBind event.

I am building this tool for my 2 home computers. Its a client/server program, which is pretty easy to program. However, as with almost all program, you encounter an error now and then. However with this error I am completely clueless to what the problem is. Basically, when I connect from my client to the server, it connects and all. I can send command lines which the server then adds to the log. I have also made a command called /screenshot which basically just takes a screenshot and send it over the connection (so I wont have to run to my 2 computers constantly xD). Anyways, the thing is, that is working fine but This other code I'm making to make it list all the Drives and the first sub-folders inside the drives, disconnects me >_> I can send the screenshot line, that works fine, but when I send the 'listfolders' command, it just disconnects me. When I go back to my other computer it just says disconnected. And it doesn't even execute the given strings. I tested it to make it send a msg box when DCing, that worked fine, but listing those drives and stuff inside a TXT or List box didn't seem to work :<Also. this code works when I make it execute it on startup, but it wont execute it when its sent by my client. So my only guess is that Microsoft has made some sort of security precaution that made you unable to make programs that could have anything to do with the folders, over a TCP connection or something :s Thats my only guess, but perhaps you see whats wrong?

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:

If this project came from an untrustworthy source, it could cause damage to your computer or compromise your private information."Two options given are:1) Load Project for Browsing2) Load Project NormallyA 'More Details' button opens a message box with:"An item referring to the file "" was found in the project file "C:UsersAdministratorAppDataLocalTemporary ProjectsWindowsApplication1WindowsApplication1.vbproj".
