Creating Custom Messages For Database Connection

Mar 24, 2012

I am trying to create error messages to display on a form. I added a label that is made visible if there is error.Currently if the database name is wrong the error message displays, however if I alter the connection string; example: If I misspell Server, the error label does not display and my application crashes when I try to click a control.How do I detect and display the error label, when there is no connection or a part of the string is misspelled or missing? Is this even possible? [code]

Sending Text Messages Using 2005 With A Mail Server?

Apr 15, 2009

I've been working on this personal project of mine and this has me stumped. I told my friend what i was trying to do and hes going to let me use his mail server that he uses at work. I have already looked on google for a sample application, but the only one i could find is not the one im looking for. Ive never worked with System.Net.Mail before so this is new to me. Im sure it would be something like this:

Imports System.Net.Mail

.NET For Each Exception On Custom Controls?

Dec 9, 2011

in VB.NET i have 2 custom controls, one is a TextBox and second one is a ComboBox.These have custom values like Bool _IsHidden and are added on runtime to a form.Now, at some point in the code I want to check if the _IsHidden is set to True or False and display that information. Since the user can edit this values when creating the control these are not set on creation.

So what I tried is:(all of this is on MDI Forms)

For Each frm as CustomForm in Main.MdiChildren If frm.MyName = calledBy Then 'this part is just to know which form called the form to create the object For Each cntrl as CustomTextBox in frm.Controls'DO Something
Next End if Next

Now.. if the first control is a custom ComboBox it thorws an error since it sees that it does not match the custom TextBox control..how do i get around this? By my understanding it should just go through all of the controls on the said form and just check those who match CustomTextBox control ?

Catch An Exception And Throw A New Exception Which Wraps The First Exception As An Inner Exception

May 8, 2009

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:

VS 2005 - Index Out Of Range Exception

Dec 13, 2010

I keep getting the error message "Index out of range exception" when I run the following code.
XX
GN3 = (Loops * 5)
For a = 1 To Loops
For b = 1 To GN3
R1 = Seeds1(Counter1)
Randomize()
R2 = CInt(Int((56 * Rnd(R1)) + 1))
Counter1 += 1
MessageBox.Show(R1 & " " & Counter1 & " " & b & " " & GN3)
Next b
Next a

The message box conforms that the last entry in the array has been reached. And that Counter1 and b both start at 1 and go to 2845. And that GN3 is also 2845 all of the time.

VS 2005 Invocation Exception Using AutoResetEvent?

May 16, 2009

I am using a background worker to process some login information. However, the background worker has to stop and wait for 2 events to happen. Once these have finished the background worker can complete its job. They are callback that will call the Set() method of the AutoResetEvent.

So I am using AutoResetEvent to set when these 2 events have finished. However, I seemed to be getting this error message

"Exception has been thrown by the target of an invocation." and Inner exception

"Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index". The exception usually fires when the registration success leaves scope.

The code for the background worker.

' Waiting for 'Account in use' and 'Register success or failure'
Private loginWaitEvents() As AutoResetEvent = { New AutoResetEvent(False), New AutoResetEvent(False) }

Thrown Custom Exception Is Immediately Caught In The Same Catch Block It Is Thrown From?

May 13, 2012

This may be a debugger issue, but here goes:I have this piece of code:

Private Function Connect() As Boolean
Try
sessionBegun = False[code].....

My intention is to 'convert' the low level exception into something more meaningful, so I throw an exception of my own creation. I want this to bubble up to a place where I can handle it.However what is happening is my debugger breaks and tells me that an exception of type "QuickBooksConnectionException" was thrown.I know that, I just threw it, why are you catching it? From what I've read, this ought to work, and there doesn't appear to be an analogous Java throws keyword, so perhaps it is my debugger.
