I feel quite silly asking this, but I couldn't find a definite answer anywhere. in vb.net, how are the array elements defined (if they are defined) for, for example:
Dim myarray(5) as int
does, at this point in time, myarray(3) for example have a defined value? If so, what is it?

I epochly failed creating an array structure. How would I build it like I tried to do with values for each data type.
Structure PovertyGuidelines Dim Id As Decimal Dim NumberOfPersons As Decimal Dim AnnualIncome As Decimal End Structure Private Data(20) As PovertyGuidelines Private Id(,) As Decimal = {{1D, 2D, 3D}} Private NumberOfPersons(,) As Decimal = {{6D, 9D, 7D}} Private AnnualIncome(,) As Decimal = {{24000D, 32000D, 27000D}}
I have this code working. It sets the Visible property of controlToSecure to False. [Code] However I would like to get rid of hardcoding types of properties. In this case i'm hardcoding Boolean. Instead I would like to define the property type dynamically. I tried it like below but I get an error on line 2 "Type property Type is not defined". I just defined that type on the line before though? Does anyone know why this doesn't work and how i could get it to work? [Code]

Actually this is vb6 to .net converted code. I m getting compile error at following line
temp = Lset(DispElem(i)) bcz Lset is not supported in .Net Lset accept string data type for first parameter and interger for second.If you know any alternet solution or if you have any source code for Explicit convert UDT to string type and vice versa.
Public Pixels(0 To 95, 0 To 127) As Variant Red = Pixels(X, Y) And &HFF i get this code from VB6, and when i transfer to VB05 i got problem said " Operator 'And' is not defined for type 'Color' and type 'Integer'. " i sent to VS2005
Public Pixels(0 To 95, 0 To 127) As Object Dim red As Object Red = Pixels(X, Y) And &HFF
In my application when i click the button i'm getting this" Operator '=' is not defined for type 'Char' and type 'Boolean'." But when i test it locally there is no problem at all!
In trying to add a bit of usage variety to a generic class I'm working on, I ran into this issue with trying to cast an object into an interface instance where the interface is defined inside the generic class.
i want to know how to type cast to user defined type in vb.net.I have a mark object which contains student id , subject name,subject id and mark. I have to read the subject id from a combo box and read corresponding mark value from it to a text box.
I am writing a scripting language which used .net for execution. Now I have written a function which accepts an object and return a set of numeric values. I wanted user to pass any numeric array (e.g. integer,single,double,long) and I could return values in that format. I mean user can retrieve value in any numeric array type rather than specifying an array type. E.g.
CultureInfo As Any (this is where it said: Type 'Any' is not defined) Dim string1 As String = "strWordGuessed" Dim string2 As String = "StrWordToGuess"
when a user inputs a value into a text box, i am searching that value in my dataset.although the number that i entered is in my dataset, i am getting this excemption.
To correct this error I use the given help that microsoft provides below and i am still getting the error messages can anyone assist me with the source codes if i send some code snippets?Check that the type definition and its reference both use the same spelling.
Check that the type definition is accessible to the reference. For example, if the type is in another module and has been declared Private, move the type definition to the referencing module or declare it Public.If the type is defined, but the object library or type library in which it is defined is not registered in Visual Basic, click Add Reference on the Project menu, and then select the appropriate object library or type library.
