I was using the following to provide more information on a common exception that can occour in a piece of my code, the only problem is this errors if an exception is generated that has no InnerException message.
Catch ex As Exception
'MessageBox.Show(ex.Message) 'If there is no InnerException.
MessageBox.Show(ex.InnerException.InnerException.Message)
End Try
Is there a better method of doing this?
I am adding data to a database table using Entity Framework. When adding a duplicate Primary Key I get an exception in InnerException.Message that reads "Violation of PRIMARY KEY constraint 'PK_StudentID'. Cannot insert duplicate key in object 'dbo.Students'. The statement has been terminated. "However, what I want to do is to rephrase this error message for the end user, but also save this exact message with the table name and column name to my logs for later. Essentially, I want to rephrase the error message to "You cannot have a duplicate entry for Student Identification Number. Please enter a new value."I have tried to inherit from System.Data.UpdateException and put an if check to see what the innerexception.message reads, and then change it accordingly. That did not work.

View 5 RepliesI am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.

I'm making a simple decoder. Type a message in the "message" text box and it spits out a code in the "code" text box. If you pop a code into the "code" text box it spits out the message in the "message" text box. Seems simple, right? Well here's my problem. I typed "The quick brown fox jumped over the lazy dog" to test it and it will put a lowercase "f" at the beginning, put letters that aren't supposed to be in there in there, and replace what should be upper case letters with lower case. I commented out the code for replacing symbols because it seemed to work fine before I put them in the code but still the same result. I checked over the code to see if I mixed stuff up. Like I accidentally put the replacement for a lower case "e" as the replacement for a lower case "h" but I can't find anything.

I am trying to have a box in the corner of my form that has continuous words added on it. Basically I want it to look like this: (each line would be added on as it occured in the form.
You entered the Castle.
You exited the castle.
You enter town.
Using messagebox.text = messagebox.text + You enter town I can get it to look like this in the box:
You entered the Castle. You exited the castle. You enter town
Is there a way I can make it so that each time something is added to the box, it appears on a new line?
