Cannot Perform '=' Operation On System.String And System.Int32

Nov 4, 2010

I get an error "Cannot perform '=' operation on System.String and System.Int32" on the following code:

VB.Net Code:

Public Sub board2_OnGameWon(ByVal sender As Object, ByVal e As EventArgs)
If Not board2.isCheated() Then
Dim time As Integer = board2.getGameTime()' I have tried changing this to String

[code]....

The exception is in the lines where I 'Dim betterScores' above. The idea is that when the player wins a game their score is placed and held in the betterScore variable. It is then written to an xml file later on.

I have a Difficulty Menu item (System.Windows.Forms ToolStripMenuItem) containing 4 choices, 3 of them work but one doesn't. The one that doesn't work is "1.0 (Normal)" and in the Sub New is "adjustDifficulty(mnuDifficulty100)"I have copied some other subs that are associated with this code below.

VB.Net Code:

Public Sub New()
' This call is required by the Windows Form Designer.
InitializeComponent()

DB/Reporting :: Error: Cannot Perform '=' Operation On System.Int32 And System.String

I wrote the code below which calculates the length of a line on the form and save record. An error occurs when the programme tries to save the record.

Extend Primitive Types Such As System.String And System.Int32?

Jul 25, 2010

Is it possible to extend primitive types such as System.String and System.Int32 (IE: integer) in .Net 4 and if so how?

To be more specific, I am aware of the concept of partial classes but this doesnt seem to be the answer. Also I find that System.String is not inheritable and Int32 is a structure.

Lastly I am interested in knowing both a VB.Net and C# answer to the above question.

C# - .net Type Mismatch Looking Up A Constructor By Reflection (Integer() Vs System.Int32[])?

Jan 29, 2010

I'm passing a type name and some parameters from C# code into a navigation framework written in VB. The navigation framework looks for a constructor on the type that matches the parameters passed in using Type.GetConstructor(Types()). The constructor that I'm looking for expects an array of integers Integer() in vb. But it gets an array of System.Int32. I've gone so far as to try this:

[Code]...

And the VB code still sees System.Int32 on the other end, which means that it doesn't find the constructor.

LINQ To SQL: Unable To Cast Object Of Type 'System.Guid' To Type 'System.String'

Nov 15, 2011

I am getting a really bizarre error and it makes no sense at all.Basically I have a user entity which has a Password property. This property is of Type Binary, the server data type being Binary(512).I am reading this value in and converting it to a byte array. However whenever I run my code I am getting a completely unrelated error of Unable to cast object of type 'System.Guid' to type 'System.String'.This strikes me as very odd since I am not using a property or variable of type string or GUID anywhere in this procedure where it falls over.

The code is below:

Public Shared Function ValidateUser(ByVal username As String, ByVal password As String) As UserValidationMessage
Using db As New EntityMapDataContext
Dim u = From user In db.Users
