When I try to add this as a service to a web app, also done in vs2010 with vb.net, I get the error in the title. Please help with this. I am not sure what is needed in order to implement a default accessor.

I am creating a simple shape editor, much like the Visual Studio form designer. You can create shapes, select them and move/resize them using drag handles just like in Visual Studio or most other applications (Visio, etc).
I have run into some problems trying to implement a MinimumSize property for the shapes.First of all, this is how I'm resizing the shapes. Each shape has a Resize method, accepting two integers (dx and dy) that represent how much the shape must resize by, and one 'HitStatus', which determines in which direction the resize must take place (for example, from the TopLeft, or Bottom, or BottomRight, etc..)
What it does basically is use a large Select Case statement for the hit status. In each case, it changes the Bounds property of the shape (which determines the location and size), so that it is resized:

I'm getting an error in this block and I'm still confused about the debugger after 6 weeks in class. I'm not asking for homework to be done simply asking where's the error in this? Full Source Code provided below
I know the error is within this code
CODE:
Scenerio:This program will implement a "List Builder", which repeatedly obtains two data elements from the user (Name and Age) and builds a list in a sequential file. The main form of the program should be similar to the following (but use your design creativity as much as desired):
#The program should have the following characteristics:
* 2 text boxes in which the user can input a name and an age. Your program should fully validate the data entered: the name should contain only letters and spaces, and the age should only contain numbers and have a reasonable range of values (let's say from 1 to 120, without decimals.)
* A Write button, which writes the data inputted into the text boxes to a sequential file. Once that data is written to the file, the textboxes should be appropriately readied for the next input.
* A File menu, with options Write and Exit. There should be a separator between the two submenu options. The submenu options should perform the same logic as the buttons with the same name.
* It is required that you use the Try..Catch statement block for every file I/O operation, so as to protect your program from unexpected run-time errors.
* A second command button that exits the application.
* As noted in the Lecture, please do not use the WriteAllText() nor ReadAllText() methods to develop your program. Instead, use the object variables and open/close methods we have been discussing in class.
# The file with the list should be saved in the default location used by VB (i.e., the "bin/Debug" folder of the solution.)
# Upon entering the program for the first time and trying to open the file, if the file already exists, the program should show a message similar to the following, and then take the appropriate action. If the file does not exist, then no message is produced. This message should be produced only once per program run (that is, not after each record is processed), and before showing the main form of the program. (Hint: consider using the form's "Load" event to accomplish this.)

Now for Part B I am being asked to extend my program so that: A - My graphic can be drawn using different colour schemes designed by me but chosen by the user B - My graphic or an appropriate part of it can be animated around the picture box if the user chooses to do so. C - Error checking is included.

How to implement such a feature in vb.net??
View 3 RepliesWe have a vb.net application where we have implemented multithreading. We determined that we need to either implement .net remoting or WCF. After researching remoting in .NET on MSDN, Microsoft considers remoting legacy for .NET framework 4.0 and recommends using WCF instead. My question is: can we implement WCF functionality into our VB.NET application or do we need to rewrite the app from the ground up in WCF?
